摘　　要：以甲基丙烯酸十八烷基酯(SMA)、丙烯酸乙酯(EA)、丙烯酸正丁酯(BA)、甲基丙烯酸甲酯(MMA)和丙烯酰胺(AAM)为单体,十六烷基三甲基溴化铵(CTAB)和吐温-20(Tween-20)为复合乳化剂,偶氮二异丁脒盐酸盐(AIBA)为引发剂,采用乳液聚合法制备无氟拒水剂乳液。通过试验得到最佳合成工艺为:复合乳化剂CTAB与Tween-20的质量比为2∶1,乳化剂质量分数为6%(对单体总质量),引发剂质量分数为0.6%(对单体总质量),单体质量分数为30%,反应温度为70℃,反应时间为3 h。该工艺制得的无氟拒水剂乳液性能优异,稳定性好。经该拒水剂整理的涤纶织物对水的接触角约可达135°。A fluonne-free waterproof agent emulsion is synthesized by emulsion polymerization using octadecyl methacrylate (SMA),ethyl acrylate (EA),n-butyl acrylate (BA),methyl methacrylate (MMA)and acrylamide (AAM)as monomers,cetyltrimethylammonium bromide (CTAB)and Tween-20as compound emulsifiers and azobisisobutylamidine hydrechloride (AIBA)as initiator.The best synthesis process is: m(Tween-20):m(CTAB)=2:1,6% emulsifier(compared to total mass monomers),0.6%initiator(compared to total mass monomers),monomers 30%,reacting at 70℃ for 3h.The prepared emulsion is fine and stable.The water contact angle of the polyester fabrics treated by the fluorine-free waterproof agent emulsion can reach 135°.
