【摘要】Surface activity of cardanol polyoxyethylene ether BGF-10 and the effects of different additives on the surface activity were studied. Results show that the critical micelle concentration (cmc)of BGF-10 is 6. 09 × 10 -6 mol/L,and the lowest surface tension (γcmc )is 38. 08 mN/m at 25 ℃. Moreover,BGF -10 displays a better resistance to hard water and a strong salt tolerance to monovalent inorganic salts. With the increase of concentration of divalent inorganic salt,the surface activity of BGF-10 is enhanced. Monohydric alcohol can reduce the surface tension of BGF-10 . The ability of BGF-10 to form micelles increases in the beginning and then decreases with the increase of monohydric alcohol concentration. BGF -10 displays a synergistic effect with other surfactants,especially with hexadecyltrimethylammonium bromide (CTAB),and its cmc synergizes upto 2. 52%,while the γcmc synergizes upto 11. 49%. BGF -10 displays a good emulsifying power for paraffin oil,as well as both thickening and defoaming performance.%研究了腰果酚聚氧乙烯醚BGF-10的表面活性及不同添加剂对其表面活性的影响.结果表明,在25℃时BGF-10的临界胶束浓度

腰果酚聚氧乙烯醚(BGF)属于直链烷基酚聚氧乙烯醚，是以天然的腰果酚为原料生产的，具有耐酸、耐碱的性能[1]，经生物降解后的产物不含烷基酚聚氧乙烯醚，

避免了对环境造成的不利影响[2]，是一种高生物降解性和环境友好型的非离子表

面活性剂。BGF适用于工业及民用清洗剂，可用作纺织精炼剂、涂料添加剂、农

药化学品中的润湿剂和乳化剂、乳液聚合中的助乳化剂和植绒胶，另外在合成纤维工业油剂中还具有除静电的效果，在合纤短纤维混纺纱浆料中可作柔软剂使用，能提高浆膜的平滑性和弹性。本文选用99%的活性成分为BGF的BGF-10为原料，其易溶于水，具有快速生物降解性，是用于洗涤剂中理想的绿色环保型表面活性剂。首次研究BGF-10的表面活性及其在洗涤应用过程中常见的影响因素，如水的硬度、常用电解质类添加剂(NaCl和Na2SO4)、增溶物(醇类)对其表面活性的影响，并进一步研究BGF-10的复配增效性能，最后对BGF-10的乳化性能、泡沫性能

和增稠性能进行研究，以期为BGF-10的应用提供理论依据。
