Designation:D816–06Standard Test Methods forRubber Cements1This standard is issued under thefixed designation D816;the number immediately following the designation indicates the year of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon(e)indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.Scope1.1These test methods cover tests to measure the properties of adhesives,commonly called rubber cements,that may be applied in plastic orfluid form and that are manufactured from natural rubber,reclaimed rubber,synthetic elastomers,or combinations of these materials.All tests are not to be considered as applicable to a particular type of adhesive nor is every test included that may be applicable to a particular type. The tests do provide standard procedures for evaluating the more important properties of the usual adhesives ordinarily classed as rubber cements.1.2The values stated in SI units are to be regarded as the standard.The values given in parentheses are for information only.1.3This standard does not purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1ASTM

procedures in which the adhesive is applied to specimens of materials to be bonded together after which the quality of the bond is evaluated,and the second including those procedures appli-cable to the adhesive itself without consideration of the bonding properties.The classes are as follows:Class I:SectionAdhesion strength8to15Bonding range16to18Softening point19to21Coldflow22to24Class II:Viscosity25Stability26to27Cold brittleness28to29Density30to31Plastic deformation32to334.Significance and Use4.1These tests are used as a means of classifying,evaluat-ing,and controlling cement compositions.Adhesion strength in tension,shear,and in a peeling mode are necessary where rubber materials are used in various engineering applications where forces are encountered both normal to the adhesion plane and parallel to the plane of the adhesive interface.5.Materials for Bonded Specimens5.1The following materials shall be used as specified for the preparation of specimens bonded with

of the adhesive bond.5.1.5Rolled Sheet or Machined Steel,SAE No.1020,sand blasted or sanded with medium/fine abrasive,and5.1.6Special materials such as leather,cork,felt,etc.6.Sampling6.1Before sampling,the cement to be tested shall be thoroughly agitated to uniform consistency throughout,after which a sample shall be taken of sufficient quantity for performance of the tests required.The sample shall be kept in a tightly closed container to prevent evaporation and shall be agitated or stirred to uniform consistency immediately before test or use in preparation of test specimens.7.Test Conditions7.1The tests of adhesives shall be conducted at a tempera-ture of2362°C(73.463.6°F)and relative humidity of506 5%.All material and equipment shall be held at these conditions prior to test for a sufficient time to assure equilib-rium.ADHESION TESTS8.Types of Adhesion Test8.1The adhesion strength of a cement used to bond two materials is measured by determining the force required to produce separation by failure of the adhesive.This force may be applied as(1)a direct tension pull in the direction normal to the adhered surfaces,(2)a shearing force in the same plane as the surfaces,or(3)a stripping or peeling force which produces progressive separation over the adhered surfaces.It is obvious that the stripping procedure can be used only when at least one of the adhered materials isflexible.Test methods,designated A,B,and C,are given for preparing and testing bonded specimens by each of these types of adhesion test.The adhesion test may also be applied,when specified,to bonded specimens that have been subjected to deteriorating influences such as accelerated aging or action of oils or solvents after their preparation and before separation,but in this case full details concerning such treatment shall accompany the statement of the result of the adhesion test.Test Method A—Adhesion Strength in Tension9.Preparation of Test Specimens9.1For testing cements for use in vulcanized applications, the test specimens shall be those specified in Section8of Test Methods D429,except that after buffing or grinding the surfaces to be adhered,and washing them free from dirt or oil using acetone,they shall be coated with a uniformfilm of the test adhesive0.025mm(0.001in.)in thickness or of an optimum thickness suitable to the products,as agreed by the parties concerned.9.2For testing cements for use in unvulcanized applica-tions,test specimens similar to those specified in9.1shall be prepared except that the rubber cylinders used in their prepa-ration shall be cut from vulcanized rubber and the assembly of the specimen shall be made without vulcanization in a mold.To accomplish this,the circular faces of the rubber cylinders shall be buffed smoothly and evenly to parallel planes and shall be coated with a uniformfilm of the test cement0.025mm (0.001in.)in thickness or of an optimum thickness suitable to the products,as agreed by the parties concerned.With thin cements,the coating may be done with a brush,applying successive coats and allowing sufficient time between coats for evaporation of the solvent.The faces of the metal plates shall be freshly sand-blasted or ground to a dullfinish withfine emery and washed free of dust and oil with trichloroethylene or perchloroethylene.The metal faces shall also be coated with the test cement as in the case of the rubber cylinders.When the cementfilms have dried to the point where there is still aggressive tackiness but no tendency for thefilm to lift when touched with afinger,each rubber cylinder shall be bonded firmly by hand between the cemented faces of two metal plates and the assembly shall be clamped in a suitable loadingfixture under a compressive load of44N(10lbf)for at least24h.10.Procedure10.1Test the prepared specimens as described in Section8 of Test Methods D429.Take care to use a tension testing machine of capacity and sensitivity suitable for loads of the magnitude anticipated with the particular adhesive being tested.Express the adhesion strength in kilopascals(or pounds per square inch)calculated by dividing the tension load causing failure by the original area of the adhered surface that separates.10.2Test two specimens and report the higher of the results as the adhesion strength in tension provided the lower value is within10%of the higher value.Otherwise,test additional specimens until results are obtained consisting of a high value and one that checks this within10%.If no check of a high value is obtained when six specimens have been tested,the average of all six results may be reported as the average adhesion strength in tension.Test Method B—Adhesion Strength in Shear11.Types of Test Specimens11.1Specimens for shear tests shall be of two types,namely, Type1lap specimens and Type2sandwich specimens,as shown in p specimens shall be used when the adhesive is to be tested for bonding materials that areboth FIG.1Test Specimens for Adhesion Strength inShearextensible such as rubber,felt,or cork,or both relatively nonextensible like metal,cloth,and leather.Sandwich-type specimens shall be used when one of the bonded materials is extensible and the other nonextensible.In both types of specimens,two strips of the material25mm(1in.)in width and125mm(5in.)in length shall be bonded over an area 625mm2(1in.2)with the free ends extending parallel in opposite directions to permit clamping in a testing machine.In the case of the laptype specimens the two strips shall be bonded directly to each other by means of the adhesive being tested, but in the case of the sandwich-type specimen a625mm2 square block of extensible material having a thickness of not more than 3.2mm(1⁄8in.)shall be bonded between two nonextensible strips by means of the test adhesive.12.Preparation of Test Specimens12.1The faces of the materials that are to be bonded by the test adhesive shall be buffed by hand using a wire brush,fine emery cloth,or similar suitable abrasive to assure a slightly roughened surface which shall then be washed free of dirt and oil with acetone.The specimens shall be allowed to dry thoroughly and the surfaces shall not be touched after washing. The test adhesive shall then be applied by brushing,spraying, or spreading to form afilm0.025mm(0.001in.)in thickness or of an optimum thickness suitable to the products,as agreed by the parties concerned.N OTE1—With cements of sufficiently heavy consistency to allow their use,the volumetric or static-mass cement spreaders shown in Fig.2andFig.3may be found convenient for applying the adhesive in preparing the required specimens.With thin cements applied by means of brushing, several coats may be necessary,in which case adequate drying time to permit evaporation of the solvent should be allowed between coats.Three such coats will usually be found sufficient.12.2When the cementfilm has dried to the point where there is still aggressive tackiness but no tendency for thefilm to lift when touched with afinger,the surfaces to be bonded shall be aligned carefully so that625mm2(1in.2)shall be adhered and pressed togetherfirmly by hand.The specimens, resting on a smooth hard base,shall then be rolled withfive complete strokes using a metal roller25mm(1in.)in diameter applied with a hand force of approximately90N(20lbf).The specimens shall then be allowed to age for at least24h under the standard test conditions of temperature and humidity (Section7)without any applied force.13.Procedure13.1After the required aging period,clamp the prepared specimen in the grips of a tension testing machine conforming to the requirements in Section8of Test Methods D413,using shims in the grips as indicated in Fig.1so that the applied force shall be in the plane of the cemented area.Take care to be certain that the specimen is properly centered and is straight in the grips.When testing Type1specimens made of extensible materials,provide for maintaining the strip during the test approximately in the plane of the clamps.This may be doneby FIG.2Volumetric CementSpreaderFIG.3Static-Mass CementSpreaderholding the specimen against a plate attached to the stationary clamp.Separate the clamps at the rate of0.8mm/s(2in./min) and record the force causing separation of the specimen in kilopascals(or pounds per square inch)of the adhered surface that separates.N OTE2—When shims or plates are added to the clamps,the testing machine must be adjusted for zero force with these additions or the force due to their mass must be deducted from the indicated reading.13.2Test two specimens in each required combination and report the higher of the results as the adhesion strength in shear, provided the lower value is within10%of the higher value. Otherwise,test additional specimens until results are obtained consisting of a high value and one that checks this within10%. If no check of the high value is obtained when six specimens have been tested,the average of all six results may be reported as the average adhesion strength in shear.Test Method C—Adhesion Strength by Stripping Method(Peeling Test)14.Preparation of Test Specimens14.1A strip offlexible material at least150mm(6in.)in length by25mm(1in.)in width shall be bonded by means of the test cement except for50mm(2in.)at one end to a strip 300mm(12in.)in length by50mm in width of the other material that is to be adhered.The center lines of the two strips shall be superimposed.The surface to be bonded shall be properly prepared,for example,by buffing,washing with acetone,drying,and coating with afilm of the test cement 0.025mm(0.001in.)in thickness or of an optimum thickness suitable to the products,as agreed by the parties concerned (Note3).Uniting,rolling down,and aging shall be done as specified in Section12for shear test specimens.N OTE3—In the case of porous material,the thickness of the cement film shall not be specified.15.Procedure15.1Place the test specimens in a tension testing machine by clamping the free end of the50-mm(2-in.)wide strip in one grip and turning back the free end of theflexible25-mm(1-in.) wide strip and clamping it in the other grip.The testing machine and the procedure used shall conform to that specified under the machine method for strip specimens in Section8of Test Methods D413.The autographic chart obtained consti-tutes the report of the test but determine the value of the adhesion by drawing on the chart the best average line between the maximum and minimum load values.Consider the load so indicated,expressed in newtons per metre(or pounds-force per inch)of width for separation at0.4mm/s(1in./min),as the adhesion strength by the stripping method.For the evaluation of each cement specimen,prepare and test two specimens and report the higher average load obtained as the adhesion strength of the specimen.BONDING RANGE16.Type of Test16.1The test for bonding range is for determining the most suitable drying period for use with the test cement after application and before bonding the materials in order to obtain the maximum initial bond strength.A series of Type2shear adhesion test specimens(Fig.1)is prepared using the test cement and allowing it to dry for different known periods before uniting the materials.These specimens are cemented, dried,bonded,and tested for adhesion strength in shear according to a definite time schedule.The drying period that results in the highest shear adhesion value is the optimum bonding range for the cement being tested.17.Preparation of Test Specimens17.1The test specimens shall be Type2shear adhesion test specimens each made from two strips of aluminum alloy 25mm(1in.)in width by125mm(5in.)in length bonded by the test cement to a block of rubber25mm square by3.2mm (1⁄8in.)in thickness having a durometer hardness of75to85. The specimens shall be prepared in duplicate as specified in Section12except that the application of the cement shall be so scheduled that successive pairs of specimens may be dried1,3, 5,10,and20min before bonding and each tested exactly3min after making the bond.After thefirst20min of drying time, additional intervals of20min to a maximum of2h shall be used.18.Procedure18.1Test the specimens prepared according to the prear-ranged schedule as specified in Section17.1,3min after making the bond and rolling them.Record for each specimen the force in newtons(or pounds-force)required to separate the rubber from the metal and select the maximum value.Report the drying time used for cementing that specimen as the optimum bonding range.If the maximum value is obtained with a specimen dried for2h,report the optimum bonding range as2h or more.SOFTENING POINT19.Type of Test19.1The test for softening point is for the determination of the temperature at which the cement softens sufficiently to provide an ineffective bond.It consists of subjecting Type2 shear adhesion test specimens(Fig.1)under a definite shearing load for a specified interval to successive increments of temperature until the bond fails.The temperature at which failure occurs is taken as the softening point.Obviously,the test is useful primarily for comparisons between different cements,as the adhesion strength may be seriously reduced at temperatures below the softening point.20.Preparation of Test Specimens20.1Type2shear adhesion test specimens(Fig.1)using the test cement shall be prepared in duplicate as specified in17.1, except that the drying time shall be that determined as the optimum bonding range and the specimens shall be aged before test at least24h under the standard conditions of temperature and humidity(Section7)without applied pressure.21.Procedure21.1Hang the test specimens with one metal end of each attached to a suitable support in an electric ovencomplyingwith the requirements in Section5of Test Method D573. Apply a force of4.5N(1lbf)by means of a static mass(Note 4)carefully without shock to the lower end of each specimen. In applying the force and suspending the specimens,use suitable clamps and shims to maintain the specimens in a vertical position and to distribute the load uniformly over the test specimens.Maintain the oven temperature at40°C(104°F) for15min and then increase0.5°C(0.9°F)/min until the rubber separates from the metal.Report the temperature at which the bond fails as the softening point of the test cement used in the specimen.N OTE4—With certain special adhesives,it may be desirable to employ very much larger forces than the4.5N(1lbf)specified.In these cases,the method may be modified accordingly,but any such change must be clearly indicated with the reported results.COLD FLOW22.Type of Test22.1The coldflow test is for evaluating the tendency for surfaces bonded by means of the test cement to slip or be displaced when subjected to various stresses for a sustained period.This yielding is considered to be due to coldflow of the adhesive.The test consists of subjecting a bonded specimen to a specified load for a prolonged period and measuring the elapsed time for failure of the bond.23.Preparation of Specimens23.1Type2shear adhesion test specimens(Fig.1)using the test cement shall be prepared in duplicate as specified in Section20.24.Procedure24.1Hang the test specimens with one metal end of each attached to a suitable support and attach a mass of0.45kg (1lb)(Note4)carefully without shock to the lower end of each specimen.In attaching the mass and suspending the specimens, use suitable clamps and shims to maintain the specimens in a vertical position and to distribute the load uniformly over the test specimens.Maintain the loaded specimens at the standard test conditions of temperature and humidity(Section7)and observe for24h or until the time of failure.Record this time as the bond failure time in the coldflow test.If no failure occurs in24h,increase the force to6.7N(1.5lbf)and observe the specimens for an additional24h as before.If the bond failure time is over24h with the4.5-N(1-lbf)force and a second period with the larger force is required,the report shall indicate a bond failure time of over24h under4.5N(1lbf)and also shall state the added time under the higher force required for failure.VISCOSITY25.Procedure25.1Determine the viscosity of the cement in accordance with Test Methods D1084,using a duplicate specimen for checking.STABILITY26.Type of Test26.1The stability test provides a means for estimating the relative life of cements in usable form prior to application. During storage many cements jell because of slow vulcaniza-tion at ordinary temperatures or other physical or chemical changes and become unusable as adhesives.These changes are evidenced by change in viscosity of the cement.The test consists of subjecting portions of the sample of the cement under specified conditions to an elevated temperature and determining the viscosity at intervals until a marked change occurs,which time is taken as a measure of the stability of the cement.27.Procedure27.1Measure twelve250-cm3portions of the sample of test cement into glass test tubes approximately38mm in diameter and300mm in length so that each tube is approximately two-thirds full.Fit the tubes with small reflux condensers and place in a constant-temperature water bath at60°C(140°F). Determine and record the viscosity of the test cement at the start of the test as specified in Section25.After1week in the water bath,remove two of the tubes,cool to room temperature, and measure for viscosity as at the start of the test.If these samples have jelled or show a marked increase in viscosity, discard all of the samples and start new ones,checking them in pairs daily.If the original samples show no appreciable change in viscosity,continue the heating forfive additional days, taking out two samples each day for viscosity determinations until marked change in viscosity occurs or the cement jells. Record and report all viscosity results.Report the number of days of heating to produce the change as the stability number of the cement.N OTE5—With some special cements made from synthetic rubbers,the viscosity may increase progressively and the cement may become unusable before showing any sudden marked change indicating jelling.In such cases,it may be desirable to test a series of samples daily in the specified manner and plot the viscosity versus time.The resulting curve may be used as the report and no stability number stated.The evaluation of the usability of the cement will depend upon the purpose for which it is intended and the materials to be bonded.COLD BRITTLENESS28.Type of Test28.1The test for cold brittleness is for evaluating and comparing the resistance of cements to cracking or chipping when bent at low temperatures.A coat of the test cement on an aluminum strip is cooled at specified temperatures for a definite time after which the strip is bent in a prescribed manner and examined visually for cracking or chipping of the cement coat.29.Procedure29.1Clean six strips of aluminum alloy25mm(1in.)in width by75mm(3in.)in length by1mm(0.040in.)in thickness and cement on one side,forming afilm of adhesive 0.025mm(0.001in.)in thickness or of an optimum thickness suitable to the products,as agreed by the parties concernedandas specified in Section12.Thefilm shall completely cover the one side of the metal.After aging for at least3h under the standard atmospheric conditions(Section7),place two of the strips in cold atmospheres at each of the following tempera-tures:−25°C(−13°F)and−40°C(−40°F).Maintain the strips at these temperatures for30min and then immediately bend double over a mandrel10mm(3⁄8in.)in diameter with the cemented side out and without removing them from the cold atmosphere.Examine the coatings for visual signs of cracking or chipping.Report a qualitative statement of the results with the cement at each temperature.DENSITY,OR MASS PER UNIT VOLUME30.Apparatus30.1The density of a cement shall be determined by use ofa calibrated pycnometer having a volume between50and 110cm3.N OTE6—If the volume is100cm3at23°C(73.4°F),the density in kg/m3is ten times the mass in grams required tofill the pycnometer.If the volume is83.3cm3at23°C,the density in lb/U.S.gal is ten times the mass required tofill the pycnometer.31.Procedure31.1Weigh the pycnometer in grams accurately to three significantfigures.Fill it with the calibration volume of the test cement which has been stirred until homogeneous and is free from air bubbles.Record thefilled mass in grams.Calculate the density or the mass per unit volume as follows:Designate the difference in the mass of thefilled pycnometer and empty pycnometer as X.Divide X by0.0833to obtain density in kg/m3.Divide X by10to obtain density in lbm/U.S.gal.PLASTIC DEFORMATION32.Type of Test32.1The test for plastic deformation is applicable only to heavy adhesives such as doughs,sealers,putties,etc.It is not suitable nor of use in the case of liquid adhesives.33.Procedure33.1Prepare two small spheres of the heavy adhesive approximately25mm(1in.)in diameter by rolling in the hands.Place these spheres on small watch glasses and heat in an air oven at125°C(257°F)for1h.Remove the spheres and examine forflow or distortion.If the spheres have suffered any marked change in shape,report the adhesive as subject to plasticflow in the deformation test.34.Report34.1The report shall include the following:34.1.1Complete identification of the test sample of cement.34.1.2Date of test and date of manufacture if known. 34.1.3Description of special materials used.34.1.4Film thicknesses used,whenever they may influence the test results,as the average thickness of adhesive layer after formation of the joint,within0.025mm(0.001in.).(The method of obtaining the thickness of the adhesive layer shall be described including procedure,location of measurements,and range of measurements.)34.1.5All observed and recorded data.34.1.6Statement of the results obtained in each of the tests required.35.Precision and Bias35.1Tests for bonding range,softening point,coldflow, stability,cold brittleness,and plastic deformation are either of a process control character or of a qualitative nature and no precision statement on these is given.36.Keywords36.1coldflow;fabric;rubber cementsASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this ers of this

4.2RC indicates the failure is at the rubber-cover cementinterface.4.3CP indicates the failure is at the cover cement-primecement interface.4.4M indicates the failure is at the metal-prime cementinterface.N OTE 1—Example —The percentages of the various types of failuremay be estimated as in the following examples:R -50,RC -50means that roughly one half or 50%of the area showedfailure in the rubber and the other 50%showed failure at the rubber covercement interface.R -25,RC -25,M -50means three types of failure were present with theM indicating 50%failure at the metal-primer interface.5.Significance and Use 5.1Method A is used to determine adhesion values in instances where users feel this design is more reflective of an actual product and where control tests have been set up as a result.The sample also lends itself to testing the effectiveness of different processing techniques and various adhesive sys-tems.6.Apparatus6.1Testing Machine —A tension testing machine conform-ing to the requirements of Practices E 4shall be used formeasuring the strength of adhesion.The moving head of themachine shall travel at the rate of 0.4060.04mm/s (1.060.1in./min).The machine shall be provided with a recordingdevice to give the total force at the conclusion of the test.Amachine of not more than 40kN (10000lbf)capacity will befound suitable in most cases.6.2Grips —The fixtures for holding the specimen in thetesting machine will depend on the type of specimen but in allcases shall be provided with ball seats to permit propercentering of the load during the test.A typical adhesion testassembly is shown in Fig.1.Specially molded laboratory specimens shall be attached by means of threaded studs on the metal parts as shown in Fig.2,but with specimens cut from production parts the clamp illustrated in Fig.3may be used.7.Standard Test Specimens 7.1The standard test specimen shall consist of a cylinder of rubber 3.260.1mm thick (0.12560.005in.)and an end area of 125065mm 2or 2.0060.01in.2(diameter of 39.960.1mm (1.59760.005in.))attached to the faces of two metal plates each at least 9.5mm (0.37in.)in thickness and of the same diameter as the rubber cylinder.The metal plates shall have smooth flat faces that shall be parallel in the finished specimen.The cylindrical shape is used to eliminate sharpcorners and to give uniform distribution of the pulling force.N OTE 2—While a 1250mm 2(2in.2)area test specimen shall beconsidered the standard for reference purposes,it shall be permissible touse a specimen of only 625mm 2(1in.2)in area,where it is desirable toprepare and cure a large number of test specimens at one time.Thediameter of this test specimen shall be 28.2160.02mm (1.12960.001in.)and the unvulcanized piece shall be cut to dimensions of approxi-mately 24mm (15⁄16in.)in diameter and approximately 5mm (3⁄16in.)inthickness (approximately 10%volume excess)boratory Preparation of Standard Test Specimens 8.1Prepare the standard test specimen to be used for development and control purposes in the laboratory as de-scribed in 8.2through 8.6.8.2Machine circular metal parts of standard dimensions from rolled bar steel SAE No.10207for standard reference pieces.However,other metals may be used if in conformity with the essential dimensions.Prepare smoothly machined test faces of the metals in accordance with any test method for securing adhesion that may be under investigation.7Supporting data are available from ASTM Headquarters.Request RR:D11-1040.FIG.1An Example of an Adhesion Test Specimen Attached in a TestingMachine8.3Cut unvulcanized rubber pieces to dimensions of ap-proximately 35mm (13⁄8in.)in diameter and approximately 5mm (3⁄16in.)in thickness so as to give maximum pressure of therubber against the metal surface during vulcanization (see Fig.2).Clean or treat surfaces to be adhered in accordance with themethod being investigated.8.4Assemble the metal parts and rubber pieces for vulca-nization in the mold.A typical mold and test piece are shownin Fig.4.The test method of assembly is illustrated in Fig.2.The mold is so constructed that there is obtained aftervulcanization approximately 0.039mm (0.0015in.)of rubberover the edge of the metal to eliminate tearing of the rubberduring test from the sharp edge of the metal.Prior to vulcani-zation,take great care to keep the surfaces to be adhered cleanand free of dust,moisture,or other foreign material.Do nottouch surfaces with the hands.8.5Vulcanize by heating the mold for a definite time at acontrolled temperature in a hydraulic vulcanization press.Choose the time and temperature of cure according to therubber compound used.At the conclusion of the cure,take carein removing the specimens from the mold to avoid subjectingthe adhered surfaces to stress before the specimens havecooled.8.6After vulcanization,store the specimens at a tempera-ture of 2362°C (73.463.6°F)at least 16h prior to testing.9.Test Specimens from Production Parts9.1For comparative test of adhesion in production parts,itis necessary to select a portion of the part so that a specimenconsisting of a rubber piece sandwiched between two parallelplates of metal may be cut.Hollow-mill specimen out of theproduction part and finish the piece either by turning orgrinding down to size in such a manner that the surfaces of therubber and metal shall be free of imperfections that would haveany tendency to start a tear in the rubber part during theapplication of tension while testing.9.2In routine production testing,it is sometimes necessaryto test specimens of different size and shape than thosespecified as standard.In such cases,the test method ofpreparation shall be similar to that given in 9.1,but the testresults secured shall not be compared with those obtained usingthe standard test specimen.10.Procedure10.1Mount the vulcanized standard test specimen or the specimen cut from a production part in the testing machine,as shown in Fig.1,using care in centering and adjustment so that the tension shall be uniformly distributed.Apply a steady tension load at the specified machine speed until the rubber either separates from the metal surface or ruptures.Record the total force at the time of failure.10.2In case of rupture in the rubber,the strength of the adhesion bond is obviously not measured,but is shown to be greater than the strength of the rubber itself.Record the type or types of failure,and express in accordance with the adhesion failure terminology described in Section 5.Estimate and record the percentages of the various types of failures.11.Calculation 11.1Express the adhesion value in pascals or pounds-force per square inch and calculate by dividing the tension force causing failure by the original area of the adhered surface that separates.In case of rupture of the rubber,the adhesion value is recognized as being higher than that reported.12.Report 12.1The report shall include the following,preferably reported on an Adhesion Test Data Sheet as illustrated in Table 1:12.1.1The result calculated in accordance with Section 11,12.1.2All observed and recorded data including the number of test pieces involved,12.1.3Notation of type or types of failure and the estimated percentages of the various types of failures (Section 10),12.1.4A description of the specimen including a statement of the test method used for securing adhesion,if known,and a notation indicating whether the specimen was molded in the laboratory or prepared from a production part,12.1.5Dimensions of the test specimen (comparisons may be made only among specimens of the same size and shape),12.1.6Date of manufacture or vulcanization,if known,12.1.7Time and temperature of vulcanization,if known,12.1.8Temperature of test room,and 12.1.9Date of test.13.Precision and Bias 713.1Precision and bias do not exist for this test method because resources necessary for round-robin testing have not beenforthcoming.FIG.2Views of a Typical Test Specimen Showing Individual Metal Parts and RubberCylindersMETHOD B—90°STRIPPING TEST—RUBBERPART ASSEMBLED TO ONE METAL PLATE14.Significance and Use14.1This test is intended for determining the adhesivestrength of rubber-to-metal bonding agents.The results areobtained by measuring the force necessary to separate a rubberfrom a metal surface.The data obtained indicate the strength ofadhesion along a line across the width of the rubber strip beingseparated from a metal plate at a 90°angle.The test providesvaluable data for development and control of rubber com-pounds and test methods of bonding,and it also serves as ascreening test for the evaluation of various bonding agents ortechniques,or both.N OTE 3—It is permissible to use a 45°angle to bring about separation,but if this is done,the same should be indicated on the form on which the data are recorded.If this notation does not appear,it must be assumed that the 90°angle has been used.The angle of pull,in this case 45°,merely means that the equipment has been so designed that the angle made by that face of the rubber being stripped from the metal and the metal to which it has been adhered is 45°.Experience indicates a lower force is obtained for the 45°angle than for the 90°angle,and also a break significantly closer to the bond interface.15.Adhesion Failure Terminology 15.1R indicates the failure is in the rubber.15.2RC indicates the failure is at the rubber-cover cement interface.15.3CP indicates the failure is at the cover cement-prime cement interface.15.4M indicates the failure is at the metal-prime cement interface.N OTE 4—Example—The percentages of the various types of failure may be estimated as in the following examples:R -50,RC -50means that roughly one half or 50%of the area showed failure in the rubber and the other 50%showed failure at the rubber-cover cement interface.R -25,RC -25,M -50means that three types of failure are present with the M indicating 50%failure at the metal-primer interface.16.Apparatus 16.1Testing Machine —A power driven test machine equipped to produce a uniform rate of grip separation shall be used for measuring the strength of adhesion.The head of the machine shall travel at the uniform rate of 0.8360.08mm/s (260.2in./min).16.2Fixture —Any suitable fixture for holding the test specimen to the upper head of the machine may be used provided the direction of pull to cause separation shall be,at all times during the test,as nearly perpendicular as possible,that is,making a 90°angle with the top holding fixture.The test fixture shown in operation in Fig.5complies with the above and provides the ease and simplicity of testing.816.3Grips —Any suitable grip may be used,provided it does not slip or rupture the rubber strip.The grip shown in Fig.5complies and provides ease and simplicity of operation.17.Standard Test Specimen 17.1The standard test specimen shall consist of a strip of rubber 6.360.1mm (0.25060.005in.)in thickness,2560.05mm (1.00060.002in.)in width,and 125mm (5in.)in length adhered to the face of a metal strip 1.660.1mm (0.06260.004in.)in thickness,2560.05mm (1.00060.002in.)in width,and 6061mm (2.3660.04in.)in length.The test specimen shall be so prepared that the bonded area of 25by 25mm (1by 1in.)is fixed approximately in the middle of the metal member as shown in Fig.6.N OTE 5—In cases where the 1.6-mm (0.062-in.)thick metal is perma-nently deformed during testing,a thicker metal may be used when agreed upon between the purchaser and the supplier.8Complete detail drawings of the fixture are available at a nominal cost fromASTM,1916Race St.,Philadelphia,PA 19103.Request Adjunct No.12-404290-00.FIG.3Method of Testing Adhesion When Sample Section isTaken from ProductionParts18.Preparation of Standard Test Specimen18.1Prepare the standard test specimen as described in18.1.1to 18.1.6:18.1.1Rectangular metal parts of the standard dimensionsdescribed in Section 17shall have the area to be bondedprepared in accordance with the test method for securingadhesion that may be under investigation.Mask both ends withpressure-sensitive tape so that only the area described inSection 17will be available for adhesion.18.1.2Cut unvulcanized rubber slabs approximately 8mm(0.3in.)in thickness to dimensions of the required size for themold,so as to provide maximum pressure of the rubber against the metal surfaces during vulcanization.(See Fig.6for suitable mold design.)The inside mold dimensions parallel to the longitudinal axis of the metal part shall be 125mm for nominal 5in.The dimension along the transverse axis of the metal part can be altered according to the number of pieces required for any one cure.This will leave sufficient length of rubber strip for fastening in the grip shown in Fig.5.Solvent-wash rubber surface to be adhered or treat in accordance with the method being investigated.Freshly milled rubber need not be solvent wiped.18.1.3Assemble the metal parts and rubber pieces for vulcanization as shown in Fig.6,properly spacing themetalin.mm

being investigated.Prior to assembly and vulcanization,take great care to keep thesurfaces to be adhered clean and free of dust,moisture,or otherforeign material.18.1.4Vulcanize by heating the mold under pressure for adefinite time at a controlled temperature in a hydraulic vulca-nizing press.The time and temperature of cure shall be inaccordance with the system being investigated.At the conclu-sion of the cure,take care in removing the specimens from themold to avoid subjecting the adhered surfaces to stress beforethe specimens have cooled.18.1.5After vulcanization,store the specimens at a tem-perature of 2362°C (73.463.6°F)for at least 16h.18.1.6Separate the specimens from each other in prepara-tion for testing.This is done by cutting with a scissors,handknife,or other suitable equipment.The edges of thespecimen may then be buffed on a belt sander to bring the edgeof the rubber flush with the edge of the metal strips (Note 6).Take care not to overheat the metal parts or the rubber and notto reduce the width of the sample being tested beyond thetolerances described.N OTE 6—Present experience indicates negligible differences in resultsbetween samples buffed clean and samples tested without buffing,possiblydue to the facts that edges of metal parts are not specifically prepared foradhesion and the edge contact area,given a metal part thickness of 1.6mm(0.062in.,)is not significant.19.Procedure19.1Place the test specimen (Note 7)symmetrically in thejaws attached to the fixed grip with the separating edge towardthe operator,as shown in Fig.5.Before the load is applied,strip the rubber from the metal plate for a distance ofapproximately 2mm (0.08in.)by using a sharp knife (Note 8).Place the tab in the grip and apply a steady load at the rate of 50mm (2.0in.)/min until separation is e the autographic recorder in order to show graphically the adhesion values over the full length of the test specimen.N OTE 7—This specimen lends itself to the determination of the relative effect of environmental conditions on possible bond deterioration.Speci-mens may be exposed unstressed or under a constant,relatively low bond stress.It is recommended that one of the standard ASTM environmental exposure conditions be used.Among those applicable are the following:Test Methods D 471,D 572,D 573,D 1149,Practice G 23,and Method B 117.If environments other than the above are used,they shall be described completely.This should include the conditions of the exposure such as time,temperature,etc.N OTE 8—Stripping the rubber from the plate initially,and as necessary during the test,is done to observe more clearly adhesion to the substrate rather than the tear strength of the stock.20.Calculations 20.1Express the adhesion value in newtons per millimetre or pounds-force per inch of width.21.Report 21.1The report shall include the following,preferably reported on an Adhesion Test Data Sheet illustrated in Table 1:21.1.1The results calculated in accordance with Section 20.21.1.2All observed and recorded data,21.1.3Notation of the type or types of failures and the estimated percentages of the various types of failures

known,21.1.7Temperature of test room,and 21.1.8Date of test.22.Precision and Bias 722.1Precision and bias do not exist for this test method because resources necessary for round-robin testing have not been forthcoming.METHOD C—MEASURING ADHESION OF RUBBER-TO-METAL WITH A CONICAL SPECIMEN 23.Significance and Use 23.1The test method is designed primarily for application to test pieces prepared in the laboratory under standard conditions in order to provide data for development and control of bonding systems and their components such as cements,or special rubber compounds,and of test methods of manufacture.While intended to be applied where rubber is bonded to supporting rigid pieces,it may not cover such cases where the support,while being of high modulus material,has a low rigidity due to small transverse dimensions,as in the case of rubber bonded to metal wires,cords or thin sheets.The particular geometry of the test piece produces,in most cases,an interfacial failure between the rubber and conical part,because of a stress concentration at the tip of the cone.24.Adhesion Failure Terminology 24.1Express the type of adhesion failure as determinedbyFIG.5Adhesion Tensile Testing Fixture inOperationexamination of broken test pieces by one or more of thefollowing symbols:24.2R indicates failure in the rubber.24.3RC indicates failure in the rubber-cover cement.24.4CP indicates failure in the cover cement-prime ce-ment.24.5M indicates failure in the prime cement-metal inter-face.N OTE 9—Example —The percentages of the various types of failuremay be estimated as in the following examples:R -50,RC -50means that roughly one half or 50%of the area showedfailure in the rubber and the other 50%showed failure at the rubber-covercement interface.R -25,RC -25,M -50means three types of failure present with the Mindicating 50%failure at the metal primer interface.25.Apparatus25.1Testing Machine —A tension testing machine conform-ing to the requirements of Practices E 4shall be used formeasuring the strength of adhesion.The moving head of themachine shall travel at the rate of 0.8360.08mm/s (2.060.2in./min).The machine shall be provided with a recordingdevice to give the force in newtons or pounds-force at theconclusion of the test.A machine of not more than 40kN or10000lbf capacity will be found suitable in most cases.25.2Grips —The fixtures for holding the specimen in thetest machine will depend on the type of specimen but in allcases shall be provided with ball seats to permit propercentering of the applied load during the test.These grips can beof two types:(1)a simple slip-in type which engages in thegrooved section of the conical specimen or (2)a threaded studwith a locknut.This could be a combination fixture.26.Standard Test Specimen26.1A standard test specimen shall consist of a rubber compound bonded to two conical metal end pieces.The diameter of the test specimen shall be 2560.5mm (1.0060.2in.).The distance between the opposed conical end pieces shall be 11.561.2mm (0.4560.05in.).For the test specimen in Fig.7,the height of each conical end piece shall be 23.460.5mm (0.9260.02in.)(Note 10).The half-angle of the cone vertex shall be 4561°and the tip shall not be rounded to radius greater than 0.8mm (0.03in.).N OTE 10—Theoretically,the height of end pieces could be any length.The end pieces in Fig.7have been the most practical size for molding and testing.boratory Preparation of Standard Test Specimens 27.1The standard test specimen is formed by two cylindri-cal rigid parts terminated by opposite conical ends,and a cylinder of rubber bonded to the conical ends.Prepare in the laboratory in accordance with 27.1.1through27.1.7.Section A-A in.0.060.120.311 1.5 2.385678mm 1.537.9253860.5127152178203FIG.6Adhesion

conical metal parts from rolled bar steel SAE No.10207or SAE No.1010for standard reference pieces.However,other rigid materials may be used if in conformity with the essential dimensions to determine the effect of adhesion on other rigid materials.Prepare the test face of the cone in accordance with any test method for securing adhesion that may be under investigation.27.1.2Vulcanize the specimens in a transfer mold.For the six-cavity transfer mold shown in Fig.8,the unvulcanized rubber piece shall be approximately 20mm (0.8in.)in thickness and 110mm (4.3in.)in diameter.Sufficient rubber stock should be used to fill the pot and provide some excess after filling the mold cavities.27.1.3Clean or treat the surface of the conical ends in accordance with the adhesion system under investigation.Coat the treated metal surface with the adhesive over the conical area only.27.1.4Place the rigid parts and the rubber compound in the preheated mold for vulcanization.27.1.5Vulcanize with conditions of time,temperature,and pressure being regulated by their interrelationship effect on adhesion to be determined.It may be necessary to surround the mold with an insulating shield to maintain proper temperature during cure.27.1.5.1At the conclusion of the cure,take great care when removing the test specimens from the mold to avoid subjecting the bonded surfaces to undue stress before the test specimens have cooled.27.1.6After vulcanization,store the specimens at a tem-perature of 2362°C (73.463.6°F)at least 16h prior to testing.27.1.7Fig.8shows a mold,unvulcanized rubber com-pound,molded test specimens,and adhesive coated conical pieces.28.Procedure 28.1Mount the test specimens in the grips of the test machine using the appropriate fixtures.Take care in centering and adjusting the test specimen so the tension is symmetrically distributed in the cross section during the test.Apply the tension load until the rubber either separates from the adhesive surface or ruptures.Record the total load at the time of failure.Record type or types of failure and express in accordance with the standard adhesion failure terminology (See Section 24).29.Calculations 29.1Express the adhesion value in newtons or pounds-force required to produce failure.In cases where the failure is in the rubber,the adhesion value is recognized as being higher than that recorded.30.Report 30.1The report shall include the following,preferably reported on an Adhesion Test Data Sheet illustrated in Table 1:30.1.1Type and code number of the rubber compound,30.1.2Cure

failure,30.1.7Date of vulcanization and date of test,and 30.1.8Temperature of testroom.FIG.8Mold and Conical TestSpecimens31.Precision and Bias31.1Precision and bias do not exist for this test method because resources necessary for round-robin testing have not been forthcoming.32.Salvaging of Bonded Metal Parts32.1Bonded metal parts may be salvaged by the usual burning or chemical stripping techniques.Mechanical or chemical surface treatments are used to re-establish a clean bonding surface.The sharpness of the conical tip may be reduced during salvaging.This affects reproducibility of the test results and care must be taken to re-establish the sharpness of this cone to 0.8-mm (0.03-in.)radius (maximum).METHOD D—ADHESION TEST:POST-VULCANIZATION(PV)BONDING OF RUBBER TO METAL33.Significance and Use33.1Methods A,B,and C of this standard cover procedures for testing the strength of adhesion of rubber to metal when the bond is formed during vulcanization.Method D may be used to determine the strength of adhesion of rubber to metal when the bond is formed after the rubber has been vulcanized.In the rubber industry,this is commonly referred to as post-vulcanization (PV)bonding.33.2In the test,a vulcanized circular disk that has been adhesive coated on both ends,is assembled between two parallel metal parts.The rubber-metal assembly is then placed in a jig under compression and heated in an oven for a specified time at a specified temperature.33.3When tested to rupture in an axial direction,a mea-surement of rubber-to-metal adhesion is obtained.The rupture force and type of failure are recorded.34.Apparatus 34.1Testing Machine ,A tension testing machine conform-ing to the requirements of Practices E 4shall be used for measuring the strength of adhesion.The crosshead of the machine shall travel at the rate of 0.8360.08mm/s (2.060.2in.)/min.The machine shall be provided with a device to record the maximum force at the conclusion of the test.A machine of at least 40kN (10000-lbf)capacity is suitable.34.2Grips —The fixtures for holding the specimen in the testing machine will depend on the type of specimen but in all cases shall be provided with ball seats to permit proper centering of the load during the test.These grips can be of the type described in 6.2of Method A and illustrated in Fig.1and Fig.3.34.3Details of the apparatus used to hold and compress the rubber metal bonded assembly during oven cure are shown in Fig.9(outside plates)and Fig.10(center aligning plate).The center aligning plate which controls compression of the bonded assembly to 10.060.1%is held to the outside plates by means of two bolts,washers,and nuts.The bolts are tightened until the metal pieces compress the rubberproperly.in.mm

vulcanized rubber test specimen in accor-dance with the procedure given in Test Method D 395.35.2The metal test specimen is identical to the standard metal test specimen described in Section 6,Method A,of this standard.36.Preparation of Standard Test Specimens36.1Place vulcanized rubber test specimens in a suitable open basket and vapor degreased (with perchloroethylene)for a period approaching,but not exceeding,5min.Remove the rubber specimens and allow to air dry at Standard Laboratory Temperature (2362°C)for a period of at least 30min.This should be in a dust-free area,preferably at low relative humidity.36.2Soak lint-free paper towel in mineral spirits (varnish and paint makers naphtha)and lay flat on a clean surface.Wipe the rubber surfaces to be bonded several times across the paper to remove any residual surface contaminants.Following air-drying for at least 15min,post-dry the cleaned rubber specimens for 10min at 70°C in a circulating air oven.Remove the rubber specimens from the oven and allow to condition at Standard Laboratory Temperature (2362°C)for at least 30min prior to adhesive coating,preferably by brush application.36.3Dip each surface of the adhesive-coated specimen alternately into a suitable assembly oil 9to a depth slightly greater than the surface to be covered.Place the specimen on its side and allow excess oil to drain off for about 5min prior to assembly.36.4Assemble the test unit in accordance with Fig.11.Required compression is automatically obtained by the spacer as the unit is tightened.36.5Place the test

胶粘剂测试
胶粘剂和胶粘试验1 引言有许多理由都需要进行胶粘剂和粘接试验,其中一些是:(1)性能比较(拉伸、剪切、剥离、弯曲、冲击和劈裂强度;耐久性、疲劳、耐环境性和传导性等)。
(2)对每批胶粘剂进行质量检查,确定是否达到标准要求。
(3)检验表面及其处理的有效性。
(4)确定对预测性能有用的参数(固化条件、干燥条件、胶层厚度等)。
试验对于材料科学和工程的各个方面都十分重要,尢其是对胶粘剂显得更为重要。
试验不仅能测定胶粘剂的本身强度,而且还能评价粘接技术、表面清洁、表面处理的有效性、表面腐蚀、胶粘剂涂布、胶层厚度和固化条件等人们非常关心的问题。
本章首先一般性地讨论粘接接头试验的各种类型,只是包括一些比较重要的试验,继而列出某些学科领域中有关的ASTM 方法和实践,以及SAE 航天局推荐的方法(ARP/s)。
2 拉伸单纯拉伸试验是负荷作用垂直于胶层平面并通过粘接面中心的试验。
ASTM D897 粘接接头拉伸强度测试方法是保留在 ASTM 中有关胶粘剂最古老的方法之一。
对于试验所用试件和夹具的制作必须给予重视,由于设计不妥,试验时会产生边缘应力,有很大的应力集中,所得到的应力数据进行类推求算不同粘接面积或不同构形接头的强度很可能是不真实的。
因此,D897 已被 D2095 (条型和圆棒试件拉伸强度测试方法)所代替。
这种试件按照 ASTM D2094 (粘接试验中条型和圆棒试件的制备)标准制作,很容易调整同心度。
如果正确地制作试件和进行试验,便能较精确地测定拉伸粘接强度。
拉伸试验是评价胶粘剂最普通的试验,尽管是有经验人员设计的接头,也不能保证加荷时完全是拉伸形式。
大多数结构材料都比胶粘剂的拉伸强度高。
拉伸试验的优点之一是能得到最基本的数据,如拉伸应变、弹性模量和拉伸强度。
加利福尼亚理工学院的维谦斯及其同事对拉伸试验的应力分布进行了分析,发现除非是当胶粘剂与被粘物的模量相匹配时,应力在整个试件里的分布是不均匀的。
这种模量的差异造成了剪切应力沿界面传递。

ASTM名称号:D429-81(再次批准1993)e1橡胶性能测试方法标准——刚性基体粘着力测试1本标准以固定号D-429发行,其后面的数字指的是最先采用的年份,括号内的数据是最新一次的批准。
e指的是最新一次批准后有所改变。
e1注—第56段的keywords,在1993年6月增加该部分1.范围1.1这些测试方法包括刚性材料与橡胶的静态粘接强度的测试步骤(在大多数情况下)方法A——橡胶件装配在两平行金属板内方法B——90°剥离测试—橡胶件装配在一金属板上方法C——圆锥体样品橡胶与金属粘着力的测量方法D——粘着力测试—硫化后(PV)金属橡胶粘着力测试方法E——90°剥离测试—橡胶油罐衬里—装配到一金属板上1.2因该测试标准可能还运用于其它刚性材料,这样的材料是常规而不是例外。
基于这个原因,在该标准中我们用“metal”(金属)而不用“rigid material”(刚性材料)。
1.3SI中的数值为标准值,而括号内的数值为参考值。
1.4该标准在使用时安全性能方面并未要求面面俱到。
该标准的使用者在使用前有责任确定一个合适的安全和健康条例和运用守则。

经过一些小的更正,方法A,B ,C,D和E也用于在合适测试样品的设计许可时获得比较粘接力测试值。
方法A,B,C,D(在橡胶用于减震目的时)许多产品上。
方法A——橡胶件装配在两平行金属板内4.意义及使用4.1 方法A用于在使用者觉得该设计更能反映实际产品和控制测试结果已经确定时来确定粘接值。
样品也可能用于不同技术处理和各种粘接系统的有效性的测试。
5.粘接破坏专业术语5.1R指橡胶内粘接破坏5.2RC指粘接破坏在橡胶界面粘合剂上5.3CP指在初粘合剂外界面的粘接破坏5.4M指在金属初粘合剂界面的粘接破坏注1 例:可以从下面的例子中预计出不同类型粘接破坏所占的百分比:R-50,RC-50指大约有50%的橡胶粘接破坏,另50%的粘接破坏在橡胶表面粘合剂上。
R-25,RC-25,M-50指3种类型的粘接破坏,M指的是有50%的粘接破坏在金属界面上。
6.设备6.1 测试机—张力测试机符合E4要求,用于粘接力强度的测试。
测试机的移动头以0.40±0.04mm/s(1.0±0.1in./min)。
测试机有记录仪器记录整个测试过程中的力。
不大于40KN的测试机在大多数情况下都适合。
6.2夹具—固定器的使用取决与样品的类型,但在测试过程中所有情况下都会用到球形座来允许载荷的中央合适位置。
图1例举了装配的粘接力的典型测试。
特殊实验室样品通过图2所示的金属件的螺纹柱固定,但从产品中取出的样品夹具如图3所示。
7.标准测试样品7.1标准测试样品包括一橡胶圆柱 3.2±0.1mm(0.125±0.005in.)端面积为1250±5mm2或2.00 ±0.01in2(直径为39.9 ±0.1mm)( 1.579 ±0.005in)附在表面最小厚度为9.5mm(0.37in)的金属片板上,和橡胶圆柱直径相同。
金属板表面光滑平整便于在样品中平行。
圆柱体避免了锋利的边缘,也利于推力平均分布。
注2—我们认为面积为1250mm2(2in2)的测试样品为参考目的标准,允许使用625 mm2(2in2)的面积,因此可以一次准备和硫化样品。
测试样品的直径为28.21±0.02 mm(1.129±0.001 in),未硫化件截成大约直径是24 mm(15/16 in)厚度大约为5 mm(3/16 in)(大约大于总体积的10%)8.标准样件的实验室里的准备8.1按8.2到8.6所述,在实验室进行开发和控制标准测试样件。
8.2用SAE NO.10207轧制钢加工圆形标准件。
然而,若是重要尺寸也可用其它金属。
在任何粘接力测试方法下,测试件的表面都应是干净平整的。
8.3将非硫化橡胶件切成直径大约是35mm(11/8in.)厚度大约为5 mm(3/16in.),以便在硫化时橡胶和金属间有最大的压力(见图2)。
按照测试方法对粘接表面进行处理。
8.4将骨架和橡胶放入橡胶模内。
典型的模具和测试样件如图4所示。
图2说明了装配的测试方法。
硫化后金属边橡胶大约为0.039mm(0.015in.)来减少在测试期间骨架的利边将橡胶撕裂。
在硫化之前,确保粘接表面无灰,无杂质,干燥。
勿用手触摸骨架及橡胶表面。
8.5在控制的温度,规定的时间内进行液压硫化。
根据橡胶成分确定硫化时间和温度。
硫化过后,在样品冷却之前取出样品避免粘接表面产生应力。
8.6硫化过后,在测试前样品至少在温度为23±2℃(73.4±3.6°F)的条件下储存16小时。
9.从产品中取出测试样品9.1对于比较粘接力测试的样品,有必要选择结构为两平行骨架内有橡胶的样品。
从产品中取出的筒形外圆铣刀样品和为适应大小要求而磨制的表面须无缺陷,以便在张力测试时无橡胶破损。
9.2对于常规产品测试,有时有必要测试不同大小和形状的样品而非标准样品。
在这样的情况下,测试方法和9.1所述的类似,但可靠的测试结果不应标准测试样品的测试结果相比较。
10.步骤10.1从产品中取出测试样品如图1安装在测试机上,小心安装和调节使得张力平均分布。
在橡胶撕裂之前在规定的速度的情况下对样品施加固定的张力载荷。
在失败时记录下总施加压力。
10.2在橡胶撕裂的情况下不测量粘接强度,但比橡胶本身强度要大。
按照第5段的专业术语记录下失败类型。
评估并记录下不同类型失败所占的百分比。
11.计算11.1用帕斯卡或重击力/平方英寸记录下粘接值,然后划分张力引起失败或计算出原粘接面积分离来计算。
若橡胶出现斯裂现象,我们认为粘接力比记录的要大。
12.报告12.1报告须包括以下内容,最好是以表1形式记录粘接力测试数据单:12.1.1按照11段计算测试结果,12.1.2所有观察和记录的数据都包括所涉及的测试样件号码,12.1.3种类的符号或失败的种类和评估出不同失败类型所占的百分比,(第10段)12.1.4样品的描述包括粘接测试方法,若知道的话,应注明产品是从实验室中做的还是从产品中取出的。
12.1.5测试样品的尺寸(仅和同等大小形状的样品相比较)。
12.1.6若知道还须注明生产或硫化的日期,12.1.7若知道还须注明硫化的时间和温度,12.1.8测试室内的温度,12.1.9测试日期13.精确度和偏差13.1在实验室内的测试和在实验室里得出的精确数据。
方法B—90°剥离测试—橡胶件和一金属板装配的情况14意义和使用14.1该测试的目的是确定橡胶—金属的粘接强度。
通过对从金属面分离橡胶所需的力来得出测试结果。
所得出的数据表明在90°情况下分离橡胶所需的粘接强度。
测试为开发和控制橡胶成分和粘接测试方法,它还为不同类型粘接技术和测试提供筛选。
注3—允许使用45°进行分离,但如果用此方法也应记录,如果没出现这样的记录,我们认为使用的是90°的分离。
推出的角度若为45°,这只说明仪器设计成该类型—橡胶和金属的面角度为45°。
实验表明由45°而非90°所获得的更低的力,而且更接近粘接表面。
15.粘接破坏专业术语15.1 R指橡胶内粘接破坏15.2 RC指粘接破坏在橡胶界面粘合剂上15.3 CP指在初粘合剂外界面的粘接破坏15.4 M指在金属初粘合剂界面的粘接破坏注4—例:可以从下面的例子中预计出不同类型粘接破坏所占的百分比:R-50,RC-50指大约有50%的橡胶粘接破坏,另50%的粘接破坏在橡胶表面粘合剂上。
R-25,RC-25,M-50指3种类型的粘接破坏,M指的是有50%的粘接破坏在金属界面上。
16.设备16.1测试机—按照6.1所述方法D412测试粘接强度。
测试机头的恒速度为0.83±0.08mm/s(2±0.2in./min)16.2装置—将样品固定到机器上部的任何合适装置,也可能用于在测试期间引起分离的推力方向(尽可能垂直到90°),也就是说,和顶部固定装置成90°角。
测试装置如图5所示(包括上部便于测试的装置)。
16.3夹具—任何合适的夹具只要不溜或弄损橡胶都可使用。
图5的夹具便于测试。
17.标准测试样品17.1标准测试样品包括厚度为 6.3±0.1mm(0.250±0.005in.)宽度为25±0.05 mm(1.000±0.002 in.),长度为125 mm的橡胶条粘接到厚度为1.6±0.1mm(0.062±0.004in.)宽度为25±0.05 mm(1.000±0.002 in.),长度为60±1 mm(2.36±0.04in.)的金属条。
测试样品剥离为25/25mm(1/1in.)大约在金属的中央地位如图6所示。
注5—在厚度为1.6mm(0.062in.)的金属片在测试时永久变形,可以在供方和买放协商同意的情况下用更厚点的金属片。
18.测试样品的准备18.1 按照18.1.1和18.1.6所述准备样品。
18.1.1如17部分所述的矩形样品标准尺寸的金属件按照测试粘接方法的还需研究决定。
用压力敏感粘接带包两端,便于17部分所述的面积可供粘接。
18.1.2将橡胶厚片切成适合模具大小,厚度大约为8mm(0.3in.),这样在硫化时金属和橡胶就有最大的压力粘接在一起(见图6)。
和金属件的纵轴平行的内模尺寸为125 mm(5in.)。
金属件横轴边的尺寸可根据硫化件数量改变。
这将为固定夹具的橡胶条留有足够的位置。
按照测试方法清洗橡胶待粘接表面在研究过程中。
18.1.3如图6所示放骨架和橡胶供硫化,将骨架放在橡胶旁,放入装置内,将金属件放入模腔内。
按照测试方法进行硫化,确保待硫化件的表面干净,干燥,无灰尘,无杂质。
