摘　　要：以甲基丙烯酸甲酯、丙烯酸正丁酯、苯乙烯为共聚单体,甲基丙烯酸异冰片酯(IBOMA)、N–丁氧基甲基丙烯酰胺(NBMA)、烯丙基聚硅氧烷(UAX806)为功能单体;联用过硫酸盐和氧化–还原为引发体系,通过种子乳液聚合制得乳胶,再与色浆配制成塑料基材用漆。考察了阴/非乳化剂配比、玻璃化转变温度(T_(g))、甲基丙烯酸异冰片酯、N–丁氧基甲基丙烯酰胺以及烯丙基聚硅氧烷等因素对塑料涂料综合性能的影响。当乳化剂m(PCA078)︰m(LPS30307)为2︰1、IBOMA用量为12%(质量分数,后同)、NBMA用量为2%、UAX806为1%时得到的乳胶综合性能最优。Methyl methacrylate,n-butyl acrylate and styrene were used as comonomers;isobornyl methacrylate,N-butoxymethylacrylamide and allyl polysiloxane were used as functional monomers.In combination with persulfate and oxidation-reduction as the initiation system,the emulsion was prepared by seed emulsion polymerization,and then formulated with the color paste to form a plastic substrate paint.The effects of anion/non-emulsifier ratio,T_(g) value,isobornyl methacrylate(IBOMA),N-butoxymethylacrylamide(NBMA) and allyl polysiloxane(UAX806) on the comprehensive properties of plastic coatings were investigated.When the ratio of emulsifier m(PCA078) and m(LPS30307) was 2∶1,the amount of IBOMA was 12%(wt.%,the same below),the amount of NBMA was 2%,and UAX806 was 1%,the comprehensive performance of the emulsion was the best.
