乳液聚合用非离子表面活性剂与APEO替代研究

Alternative Research on Emulsion Polymerization with Non Ion Surface Activeagent and APEO

就几种不同的环保或不环保的(含APEO)非离子表面活性剂对乳液聚合的影响进行一些探讨与研究,寻找APEO的替代品及乳液聚合过程中对乳液稳定性的影响。表面活性剂(特别是非离子型)是乳液聚合中的重要助剂,其性能很大程度上决定了乳液的最终性能:乳液稳定性、乳液粒子粒径大小、成品性能(耐水性、成膜性能、力学性能、粘结性能等)等等[1],由于传统性能优异的APEO越来越大范围禁用,选择绿色环保的非离子表面活性剂是从事合成乳液的化学专家重要任务。研究结果表明市场上绿色环保的非离子表面活性剂基本可替代APEO,效果与APEO比或稍有不如,也有综合性能较为特出的如SRNIE非离子表面活性剂,明显比APEO优胜。

Several different environmental or not environmental protections, including APEO, some to explore and research the effect of nonionic surfactants on emulsion polymerization, influence on the stability of the emulsion to find alternatives and APEO emulsion polymerization process. Surface active agent, especially nonionic emulsion important task of emulsion. The results showed that the market of nonionic surfactant green basic alternative to APEO, and APEO than or slightly less, but also a comprehensive performance was outstanding as SRNIE non - ionic surface active agent, obviously superior to APEO.
