添加剂助PVC提高耐寒性的配方

添加剂助PVC提高耐寒性的配方PVC管塑料是五大通用合成塑料之一，是目前世界上仅次于聚乙烯的第二大塑料品种。

PVC塑料具有良好的物理及机械性能，可用于生产建筑材料、包装材料、电子材料、日用消费品等，广泛应用于工业、农业、建筑、交通运输、电力电讯和包装等各领域。

由于其耐寒性和低温抗冲击性能较差，硬PVC的使用温度下限一般为-15ºC，限制了PVC材料在某些方面的应用。

通过对PVC树脂和助剂的调整，可以有效地提高PVC塑料的耐寒性，满足低温需要。

本文着重从配方角度论述了提高PVC耐寒性的一些方法，供大家参考。

1、PVC树脂PVC树脂是一种非结晶、极性的高分子聚合物，其玻璃化温度依分子量大小为75~105ºC，相对分子质量越大，粘数越高，PVC大分子链间范德华引力或缠绕程度相应增加，PVC链段增长，材料的耐低温性愈好。

在常规PVC配方中，如只需应付北方冬季寒冷气候，可采用选取粘数稍高，即平均分子量稍大的PVC 树脂，可以是同一牌号中粘数值偏高的PVC或更低牌号树脂。

另外，在一些特殊要求的制品中，如可耐-30ºC的血袋等制品中，可选用高聚合度聚氯乙烯树脂（平均聚合度大于2000）[1]，这是因为高聚合度PVC有着比常规PVC树脂大的结晶度和类交联结构，使大分子间滑动困难，弹性增加，同时分子量增大，分子间范德华力和分子内化学键合力增加而获得优良的耐寒性。

2、增塑剂增塑剂作为PVC软制品的重要配方组分，对软制品的性能影响很大，如要求制品在低温下使用，必须选择好增塑剂的类型。

目前作为耐寒性增塑剂使用的主要有脂肪酸二元酸酯、直链醇的邻苯二甲酸酯、二元醇的脂肪酸酯以及环氧脂肪酸单酯等。

据报道，N,N-二取代脂肪酸酰胺、环烷二羧酸酯，以及氯甲氧基脂肪酸酯等，也是低温性能优良的耐寒增塑剂。

提高PVC软制品的耐寒性，一般可通过增加耐寒增塑剂的用量来获得。

DOA（己二酸二辛酯）、DIDA （己二酸二异癸酯）、DOZ（壬二酸二辛酯）、DOS（癸二酸二辛酯）是作为耐寒增塑剂使用的代表性品种，由于一般耐寒增塑剂与PVC的相容性都不十分好，实际上只能作为改善耐寒性的辅助增塑剂使用，其用量通常为主增塑剂的5~20%。

pvc同质透心生产工艺流程

pvc同质透心生产工艺流程英文回答：PVC (Polyvinyl chloride) is a widely used thermoplastic polymer that can be produced using various manufacturing processes. One of the commonly used processes for producing PVC is the homogeneous through-the-core process.The homogeneous through-the-core process involves the following steps:1. Polymerization: The process begins with the polymerization of vinyl chloride monomer. This is typically carried out in a batch reactor or a continuous reactor. In the reactor, vinyl chloride monomer is subjected to heat and pressure, along with a catalyst, to initiate the polymerization reaction. The reaction results in the formation of PVC resin.2. Mixing and compounding: After polymerization, thePVC resin is mixed with various additives and modifiers to improve its properties. Additives such as plasticizers, stabilizers, lubricants, and fillers are added to enhance flexibility, heat resistance, and processability of the PVC resin. The mixture is then compounded using mixing equipment to ensure uniform distribution of additives throughout the resin.3. Extrusion: The compounded PVC resin is then fed into an extruder, which is a machine that melts the resin and forms it into a continuous profile. The extruder consistsof a barrel, a screw, and a die. The resin is fed into the barrel, where it is heated and melted by the rotating screw. The molten PVC is then forced through the die, which shapes it into the desired profile, such as pipes, sheets, or profiles.4. Cooling and sizing: After extrusion, the PVC profile is cooled using a water bath or air cooling system. The cooling process solidifies the molten PVC and helps in maintaining its shape. The cooled profile is then passed through a sizing device, which ensures that the finalproduct has the desired dimensions and tolerances.5. Finishing and packaging: Once the PVC profile has been sized, it undergoes various finishing processes, such as cutting, drilling, or embossing, to meet specific customer requirements. The finished profiles are then packaged and prepared for shipment.中文回答：PVC（聚氯乙烯）是一种广泛使用的热塑性聚合物，可以通过多种生产工艺进行生产。

PVC常用的添加剂类型与功能

PVC塑料的合成PVC塑料是由乙炔气体和氯化氢合成氯乙烯，再聚合而成。

在20世纪50年代前期是以乙炔电石法生产，50年代后期则转向了原料充足、成本低廉的乙烯氧化法；目前世界上80%以上的PVC树脂都是由此方法生产的。

但到2003年后，因石油价格暴涨，乙炔电石法成本反而比乙烯氧化法还要低10%左右，所以PVC的合成工艺又转向了乙炔电石法。

PVC塑料是由液态的氯乙烯单体（VCM）经悬浮、乳液、本体或溶液法工艺聚合而成，其中悬浮聚合工艺生产工艺成熟、操作简单、生产成本低、产品品种多、应用范围广，一直是生产PVC树脂的主要方法，在世界PVC生产装置中大约占90%的比例（在世界PVC总产量中均聚物也占大约90%的比例）。

其次是乳液法，用于生产PVC糊树脂。

其聚合反应由自由基引发，反应温度一般为40～70OC，反应温度和引发剂的浓度对聚合反应速率和PVC 树脂的分子量分布影响很大。

悬浮聚合悬浮聚合通过不断进行搅拌使单体液滴在水中保持悬浮状态，聚合反应在单体小液滴中进行。

通常悬浮聚合反应为间歇聚合。

近年来各公司对PVC树脂间歇悬浮聚合工艺的配方、聚合釜、产品品种和质量不断研究和改进，开发出各具特点的工艺技术，目前应用较多的是Geon公司（原B.F Goodrichg公司）技术、日本信越公司技术、欧洲EVC 公司技术, 这三大公司的技术在1990年以来世界新增的PVC树脂生产能力中各占大约21%的比例。

乳液聚合乳液聚合与悬浮聚合基本类似，只是要采用更为大量的乳化剂，并且不是溶于水中而是溶于单体中。

这种聚合体系可以有效防止聚合物粒子的凝聚，从而得到粒径很小的聚合物树脂，一般乳液法生产的PVC树脂的粒径为0.1—0.2mm，悬浮法为20―200mm。

引发剂体系与悬浮聚合也有所不同，通常是含有过硫酸盐的氧化还原体系。

干燥方法也设计成可以保持较小的粒径的方式, 常常采用一些喷雾干燥剂。

由于不可能将乳化剂完全除去，因此用乳液法生产的树脂不能用于生产需要高透明性的制品如包装薄膜或要求吸水性很低的制品如电线绝缘层。

PVC稳定剂简介

PVC稳定剂简介之答禄夫天创作英文化工术语:Stabilizer, Inhibiter.什么是稳定剂？1、广义地讲,能增加溶液、胶体、固体、混合物的稳定性能化学物都叫稳定剂.它可以减慢反应,坚持化学平衡,降低概况张力,防止光、热分解或氧化分解等作用.广义的化学稳定剂来源非常广泛,主要根据配方设计者的设计目的,可以灵活的使用任何化学物以到达产物品质稳定的目的.2、狭义地讲,主要是指坚持高聚物塑料、橡胶、合成纤维等稳定,防止其分解、老化的试剂.纯的PVC树脂对热极为敏感,当加热温度到达90Y：以上时,就会发生轻微的热分解反应,当温度升到120C后分解反应加剧,在150C,10分钟,PVC树脂就由原来的白色逐步酿成黄色—红色—棕色—黑色.PVC树脂分解过程是由于脱HCL反应引起的一系列连锁反应,最后招致年夜分子链断裂.防止PVC热分解的热稳定机理是通过如下几方面来实现的.通过捕捉PVC热分解发生的HCl,防止HCl的催化降解作用.铅盐类主要按此机理作用 ,另外还有金属皂类、有机锡类、亚磷酸脂类及环氧类等.•置换活泼的烯丙基氯原子.金属皂类、亚磷酸脂类和有机锡类可按此机理作用.•与自由基反应,终止自由基的反应.有机锡类和亚磷酸脂按此机理作用.•与共扼双键加成作用,抑制共扼链的增长.有机锡类与环氧类按此机理作用.•分解过氧化物,减少自由基的数目.有机锡和亚磷酸脂按此机理作用.•钝化有催化脱HCl作用的金属离子.同一种稳定剂可按几种分歧的机理实现热稳定目的.铅盐类铅盐类是PVC最经常使用的热稳定剂,也是十分有效的热稳定剂,其用量可占PVC热稳定剂的70％以上.铅盐类稳定剂的优点：热稳定性优良,具有长期热稳定性,电气绝缘性能优良,耐候性好,价格低.铅盐类稳定剂的缺点：分散性差、毒性年夜、有早期着色性,难以获得透明制品,也难以获得鲜明色彩的制品,缺乏润滑性,易发生硫污染.经常使用的铅盐类稳定剂有：(1)三盐基硫酸铅分子式为3PbO．PbSO．H20,代号为TLS,简称三盐,白色粉末,密度6．4g／cm’.三盐基硫酸铅是最经常使用的稳定剂品种,一般与二盐亚磷酸铅一起并用,因无润滑性而需配人润滑剂.主要用于PVC硬质不透明制品中,用量一般2~7份.(2)二盐基亚磷酸铅分子式为2PbO．PbHPO3.H2O,代号为DL,简称二盐,白色粉末,密度为6．1g／cm3.二盐基亚磷酸铅的热稳定性稍低于三盐基硫酸铅,但耐候性能好于三盐基硫酸铅.二盐基亚磷酸铅常与三盐基硫酸铅并用,用量一般为三盐基硫酸铅的1／2.(3)二盐基硬脂酸铅代号为DLS,不如三盐基硫酸铅、二盐基亚磷酸铅经常使用,具有润滑性.常与三盐基硫酸铅、二盐基亚磷酸铅并用,用量为0．5—1．5份.复合铅盐稳定剂铅盐稳定剂价格昂贵,热稳定性好,一直被广泛使用,但铅盐的粉末细小,配料和混合中,其粉尘被人吸入会造成铅中毒,为此,科技人员又研究出一种新型的复合铅盐热稳定剂.这种复合助剂采纳了共生反应技术将三盐、二盐和金属皂在反应体系内以初生态的晶粒尺寸和各种润滑剂进行混合,以保证热稳定剂在PVC体系中的充沛分散,同时由于与润滑剂共熔融形成颗粒状,也防止了因铅粉尘造成的中毒.复合铅盐稳定剂包容了加工所需要的热稳定剂组份和润滑剂组份,被称作为全包装热稳定剂.它具有以下的优点：(1)复合热稳定剂的各种组份在其生产过程中可获得充沛混合,年夜幅度改善了与树脂混合分散的均匀性.(2)配方混合时,简化了计量次数,减少了计量毛病的概率及由此所带来的损失.(3)简便了辅料的供应和贮备,有利于生产、质量管理.(4)提供了无尘生产产物的可能性,改善了生产条件.总之,复合热稳定剂有利于规模生产,为铅盐热稳定剂的发展提供了新的方向.复合铅盐稳定剂一个重要指标是铅的含量,目前所生产的复合铅盐稳定剂含铅量一般为20％-60％；在PVC 塑料门窗型材生产上的用量为3．5—6份金属皂类简介为用量仅次于铅盐的第二年夜类主稳定剂,其热稳定性虽不如铅盐类,但兼具润滑性.金属皂类可以是脂肪酸(月桂酸、硬脂酸、环烷酸等)的金属(铅、钡、镉、锌、钙等)盐,其中以硬脂酸盐最为经常使用,其活泼性年夜小顺序为：Zn盐?Cd盐?Pb 盐?Ca盐7．Ba盐.金属皂类一般不独自使用,经常为金属皂类之间或与铅盐及有机锡等并用.除Gd、Pb外都无毒,除Pb、Ca外都透明,无硫化污染,因而广泛用于软质PVC中,如无毒类、透明类制品等.经常使用的金属盐类稳定剂有(1)硬脂酸锌(ZnSt),无毒且透明,用量年夜后,易引起“锌烧”制品变黑,常与Ba、Ca皂并用.(2)硬脂酸镉(CdSt),为一重要的透明稳定剂品种,毒性较年夜,不耐硫化污染,抑制早期变色能力年夜,常与Ba皂并用.(3)硬脂酸铅(PbSt),热稳定性好,可兼做润滑剂.缺点为易析出,透明差,有毒且硫化污染严重,常与Ba、Cd皂并用.(4)硬脂酸钙(CaSt),加工性能好、热稳定能力较低,无硫化污染,无毒,常与Zn皂并用.(5)硬脂酸钡(BaSt),无毒,长期热稳定性好,抗硫化污染,透明,常与Pb、Ca皂并用.复合品种经常使用的有：Ca／Zn(无毒、透明)、Ba／Zn(无毒、透明)、Ba／Cd(有毒、透明)及Ba ／Cd／Zn.有机锡类有机锡类为热稳定剂中最有效的,在透明和无毒制品中应用最广泛的一类,其突出优点为：热稳定性好,透明性好,年夜大都无毒.缺点为价格高,无润滑性.有机锡类年夜部份为液体,只有少数为固体.可以独自使用,也常与金属皂类并用.有机锡类热稳定剂主要包括含硫有机锡和有机锡羧酸盐两类.(1)含硫有机锡类：主要为硫醇有机锡和有机锡硫化物类稳定剂,与Pb、Cd皂并用会发生硫污.含硫有机锡类透明性好.主要品种有：a、二巯基乙酸异辛酯二正辛基锡(DOTTG),外观为淡黄色液体,热稳定性及透明性极好,无毒,加入量低于2份.b、二甲基二巯基乙酸异辛酯锡(DMTFG),外观为淡黄廓清液体,为无毒、高效、透明稳定剂,经常使用于扭结膜及透明膜中.(2)有机锡羧酸盐：稳定性不如含硫有机锡,但无硫污染,主要包括脂肪酸锡盐和马来酸锡盐.主要品种有：a、二月桂酸二正丁基锡(DBTL)淡黄色液体或半固体,润滑性优良,透明性好,但有毒,常与Cd皂并用,用量1-2份；与马来酸锡及硫醇锡并用,用量0.5—1份.b、二月桂酸二正辛基锡(DOTL),有毒且价高,润滑性优良,经常使用于硬PVC中,用量小于1．5份.c、马来酸二正丁基锡(DBTM),白色粉末,有毒,无润滑性,常与月桂酸锡并用,不成与金属皂类并用于透明制品中.有机锑类具有优秀的早期色相和色相坚持性,尤其是在低用量时,热稳定性优于有机锡类,特别适于用双螺杆挤出机的PVC配方使用.有机锑类主要包括硫醇锑盐类、巯基乙酸酯硫醇锑类、巯基羧酸酯锑类及羧酸酯锑类等.国内的锑稳定剂主要以三巯基乙酸异辛酯锑(ST)和以ST为主要成份的复合稳定剂STH—I和STH-Ⅱ两种为主.五硫醇锑为透明液体,可用作透明片、薄膜、透明粒料的热稳定剂.STH-I可以取代京锡C-102,可抑制PVC的早期着色,热稳定性好,制品透明,颜色鲜艳,STH—Ⅱ无毒,主要用于PVC水管等.稀土稳定剂选材多为稀土氧化物和稀土氯化物为主,其氧化物和氯化物多为镧、铈、镨、钕等轻稀土元素的单一体或混合体.稀土元素有着相似且异常活泼的化学性质,有着众多的轨道可作为中心离子接受配位体的孤对电子,同时稀土金属离子有较年夜的离子半径,与无机或有机配位体主要通过静电引力形成离子配键,作为络合物的中心原子,常以d2SP3、d4dP3、f3d5Ssp3等多种杂化形式形成配位数为6—12的络合物.稀土元素优良的力学性能及其分组原理都与稀土元素的几何性质有关.因为原子和离子的半径是决定晶体的构型、硬度、密度和熔点等物理性质的重要因素,在常温、常压条件下,稀土金属镧、镨、钕呈双六方晶体结构,而铈呈立方晶体密集(面心)结构,当温度、压力变动时,大都稀土金属发生晶型转变.由于镧系收缩,镧系元素的原子半径、原子体积随原子序数增加而减小,密度随原子序数增加而增加,但铈与镧、镨、钕相比,有异常现象.在镧、铈、镨、钕中,镧的化学性质是最活泼,但三价镧与C1只能生成RECl正络合物,而且此络合物不稳定,而铈、镨这些高价的稀土离子与Cl生成络合物的能力比三价的镧要强,它们与Cl配体能生成稳定的负络离子,因此,在稀土热稳定剂的选材上要综合镧、铈、镨、钕的各自优点,在分歧的应用范围,用其高纯单一体、混合体或合理搭配.稀土离子为典范的硬阳离子,即不容易极化变形的离子,它们与金属硬碱的配位原子,如氧的络合能力很强.稀土化合物对CaC03的偶联作用,由于稀土离子和PVC链的氯离子之间存在强配位相互作用,有利于剪切力的传递从而使稀土化合物能有效地加速PVC的凝胶化,即可增进PVC塑化,又可起到加工助剂ACR 的作用.同时,稀土金属离子与CPE中的C1配位,可使CPE更加发挥其增韧改性的作用.这些效能发挥的充沛与否、平衡与否,与稀土复合物中的复配助剂有着相当年夜的关系,复合物中的润滑体系、加工改性体系都至关重要,因此复配工艺的好坏直接影响着稀土多功能复合稳定剂的效能.稀土稳定剂功能性能优良的稀土稳定剂应具有以下功能：(1)优异的热稳定性能静态静态热稳定性,均与京锡8831相当,好于铅盐及金属皂类,是铅盐的三倍及Ba／Zn复合稳定剂的4倍.可复配成为无毒、透明的,还可部份取代有机锡类稳定剂而广泛应用.稀土稳定剂的作用机理为捕捉HCl和置换烯丙基氯原子,与环氧类的辅助稳定剂具有较好的协同作用.(2)偶联作用具有优良的偶联作用,与铅盐相比,与PVC有很好的相容作用,对PVC-CaCO,体系偶联作用较好,有利于PVC塑料门窗异型材强度的提高.用稀土稳定剂加工的PVC型材的焊角强度比铅盐稳定剂的PVC型材焊角强度要高,原料价格也高一些.(3)增韧作用与PVC树脂和增韧剂CPE的良好的相容性以及与CaCO3,的偶联作用,使PVC树脂在加工中塑化均匀,塑化温度低,型材的耐冲击性能较好.稀土稳定剂无润滑作用,应与润滑剂一起加入, 目前我国生产的稀土复合稳定剂是将稀土、热稳定剂和润滑剂复配而成的,加入量一般为4-6份.主要的辅助热稳定剂品种辅助垫稳定剂自己不具有热稳定作用,只有与主稳定剂一起并用,才会发生热稳定效果,并增进主稳定剂的稳定效果.辅助热稳定剂一般不含金属,因此也称为非金属热稳定剂.辅助热稳定剂的主要品种有：(1)亚磷酸酯类.是一重要的辅助热稳定剂,与Ba／Cd、Ba ／Zn复合稳定剂及Ca／Zn复合稳定剂等有协同作用,主要用于软质PVC透明配方中,用量为0．1—1份.(2)环氧化合物类,与金属皂类有协同作用,与有机锡类稀土稳定剂并用效果好,用量为2-5份,经常使用的品种为环氧年夜豆油、环氧脂.(3)多元醇类,主要有季戊四醇、木糖醇、甘露醇等,可与Ca ／Zn复合稳定剂并用.。
