摘要
以苯乙烯（St）、甲基丙烯酸甲酯（MMA）和丙烯酸丁酯（BA）为共聚单体,丙烯酸（AA）为功能单体,反应型乳化剂（DNS-86）、十二烷基硫酸钠（SDS）和壬基酚醚磺基琥珀酸酯钠盐（OS）为复合乳化剂,采用种子乳液聚合法制备了粒径小、耐水性好且固含量为50%的苯丙微乳液。研究结果表明：当w（引发剂）=0.7%、m（MMA＋St）∶m（BA）∶m（AA）=5.0∶4.7∶0.3、w（St）=15%~25%、m（DNS-86）∶m（SDS＋OS）=3∶2且w（复合乳化剂）=5%时,高固含量苯丙微乳液的综合性能良好。
With styrene（St）,methyl methacrylate（MMA） and butyl acrylate（BA） as comonomers,acrylic acid（AA） as function monomer,reactive emulsifier（DNS-86）,sodium dodecyl sulfate（SDS） and OS as composite emulsifier,a St/acrylate micro-emulsion with smaller particle diameter,better water resistance and higher solid content（50%） was prepared by seed-emulsion polymerization.The research results showed that the St/acrylate micro-emulsion with higher solid content had good combination property when mass fractions of initiator and St were 0.7% and 15%-25% respectively,mass ratio of m（MMA＋St）∶m（BA）∶m（AA） was 5.0∶4.7∶0.3,mass ratio of m（DNS-86）∶m（SDS＋OS） was 3∶2 and mass fraction of composite emulsifier was 5%.
