摘　　要：通过八甲基环四硅氧烷、十八烷基甲基二甲氧基硅烷、γ-巯丙基甲基二甲氧基硅烷和氨基丙基甲基二甲氧基硅烷的反应合成了可反应性梳型聚硅氧烷(Si-SH),再用Si-SH与全氟己基乙基甲基丙烯酸酯(C6SFMA)、丙烯酸十八酯(SA)、N-羟丙基丙烯酰胺(NMA)乳液聚合,得到的梳型有机硅改性含氟丙烯酸酯乳液。当乳化剂用量为2.0%、C6SFMA用量为18.0%、SA与Si-SH的质量比为3:7、NMA用量为0.6%时综合性能最好,乳液整理过的棉织物具有优良的拒水拒油效果。A reactive comb-like polysiloxane(Si-SH)was synthesized by using octamethylcyclotetrasiloxane,dimethoxymethyloctadecylsilane methyl sulfhydrylpropyl dimethoxy silane,γ-aminopropyl methyl diethoxysilane.A comb-like silicone modified fluorinated polyacrylate emulsion was prepared by emulsion polymerization with Si-SH,2-(Perfluorohexyl)ethyl methacrylate(C6SFMA),octadecyl acrylate(SA),n-Hydroxy propyl acrylamide(NMA).The results showed that the comprehensive performance was excellent when emulsifier was 2.0%,C6SFMA was 18.0%,the weight ratio of Si-SH/SA was 3:7,NMA was 0.8%.The water and oil repellency of cotton fabric treated with this emulsion was excellent.
