摘　　要：采用有机硅和丙烯酸共聚,制备出性能优良的有机硅丙烯酸乳液。研究有机硅单体用量、油水比、软硬单体比、乳化剂等因素对乳液及膜性能的影响。结果表明:当有机硅占单体13%,油水比0.9,软硬比为1/0.8,乳化剂烷基酚聚氧乙烯醚(OP-10):十二烷基磺酸钠(SLS)为2/1,乳化剂占单体的3%,引发剂占单体0.5%,电解质占单体0.75%时,单体转化率高,得到乳液及膜性能符合国家标准GB/T20623-2006《建筑涂料用乳液》。对固化膜做IR分析结果显示有机硅单体成功接枝到丙烯酸聚合物上。Silicone-Acrylate emulsion was prepared by organic silicone and acrylic ester. The Grease-water proportion,initiator content, emulsifier content and rate, electrolytical dos- age and Silicone content effect on the properties of emulsion and film were studied. It is found that the performance of Silicone-Acrylate Emulsion and Membrane performance are excellent when the Grease-water proportion is 0.9 ,electrolytical dosage is 0.75% ,0. 5% ini- tiator,the appropriate rate of OP-10 and SLS is 2：1 ,the right amount of emulsifier is 3% silicone content of oily total monomers of 13 %. Emulsion and film properties meeting the national standard GB/T20623-2006＂ Emulsions for Architectural Coatings＂. And IR analysis of the cured film showed that the silicone and acrylic finish effective crosslinking.
