摘要

研究了有机硅氧烷单体的种类、用量和添加方式以及水解抑制剂用量、体系的pH值、复合乳化剂的配比对自交联型有机硅氧烷改性丙烯酸乳液稳定性的影响并揭示其规律.发现采用含异丙氧基结构的阻碍性有机硅氧烷单体、调节反应体系的pH值在4.5～7的范围内、在反应体系中加入适量的水解抑制剂或采用有机硅氧烷的后添加方式都能减少和抑制有机硅氧烷在水中的水解反应和缩聚反应，提高聚合反应稳定性，增加产物中有机硅氧烷的含量，从而提高硅丙乳液性能.

Abstract

The effect of species

level and procedure of adding organic siloxane

content of hydrolyzation inhibiter

pH value and partition of composite emulsifier between nucleus and shell on the stability of acrylate emulsion was studied. The result showed that using hindering organic siloxane monomer with isopropoxy

adjusting the pH value in the range of 4.5—7

adding the right amount of hydrolyzation inhibitor

and taking post addition of organic siloxane can decrease the degree of hydrolyzation and fasculation

improve polymerization stability and increase the graft ratio and content of organic siloxane

and hence obtain an emulsion with good performance.
