摘　　要：以甲基丙烯酸六氟丁酯(FA-02)、甲基丙烯酸甲酯(MMA)及丙烯酸丁酯(BA)为原料,采用核壳乳液聚合法,合成了核壳型含氟防水透湿整理剂乳液。当壳层单体FA-02与BA质量比为3.5∶1、核壳乳化剂FS-200与LAS的体积比为1∶1、壳层预乳化液滴加时间为90 min、乳化剂用量为1.8%、单体转化率达到90%、交联单体甲基丙烯酸羟乙酯(HEMA)用量为2%时,可以合成外观透亮、细腻、性能稳定的乳液。在最佳防水透湿整理工艺下,核壳型含氟防水透湿整理剂整理后的棉织物对水的接触角可以达到129.3°,透湿量为2 319.3 g/m2·24 h。Core-shell fluorine-containing waterproof and moisture transmission agent is synthesized by core-shell emulsion polymerization with hexafluorobutyl methacrylate（FA-02）,methyl methacrylate（MMA） and butyl acrylate as raw materials.Translucent,delicate and stable emulsion can be obtained under reaction conditions of mass ratio of FA-02 to BA of 3.5∶1,volume ratio of core-shell emulsifiers 1 ∶ 1,dropping time of shell pre-emulsion 90 min,emulsifier dosage 1.8%,conversion rate of monomer 90% and HEMA dosage 2%.Water contact angle of the finished cotton fabric is 129.3° and moisture transmission is 2 319.3 g/m^2 · 24 h with optimized finish process.
