摘　　要：采用甲基丙烯酸十二氟庚酯(Actyflon-G04)、甲基丙烯酸甲酯(MMA)、丙烯酸丁酯(BA)为主要单体,脂肪醇聚氧乙烯醚(AEO-9)和十二烷基硫酸钠(SDS)为复配乳化剂,过硫酸铵(APS)为引发剂,通过半连续种子乳液聚合法,制备出新型含氟丙烯酸酯共聚物乳液.分析了该含氟丙烯酸酯拒水剂的最佳合成工艺,并应用到棉织物上.最佳合成工艺为:m(BA)∶m(MMA)=5∶3,Actyflon-G0430%(对单体总质量),乳化剂2.5%(对单体总质量),引发剂0.9%(对单体总质量),聚合反应温度80℃,保温时间3 h.将拒水剂处理到棉织物上,整理后织物对水的接触角可达125.0°,耐静水压为145.8 mm,具有良好的拒水效果,并且织物手感、透气性能变化不大.New fluorinated acrylate copolymer emulsion was prepared using dodecafluoroheptyl methacry-late （Actyflon- G04）, methyl methacrylate （MMA）, butyl acrylate （BA） as the monomers, fatty alcohol polyoxy-ethylene ether （AEO- 9） and sodium dodecyl sulfate （SDS） as emulsifier, ammonium persulfate as initiator through semi- continuous seed emulsion polymerization method. The optimal synthesis process of new fluori-nated acrylate water repel ent was analyzed. The prepared copolymer was applied in cotton fabric. The results showed that the optimum synthesis conditions were 5∶3 of BA and MMA mass ratio, 30% of Actyflon- G04 （on the total mass of monomers）, 2.5% of emulsifier （on the total mass of monomers）, 0.9% of initiator （on the total mass of monomers）, 80 ℃ of polymerization temperature, 3 h of holding time. And the synthetic co-polymers was applied in cotton fabric, the water contact angle of finished cotton fabric was up to 125.0° , the hydrostatic pressure was up to 145.8 mm. The prepared fluorinated acrylate emulsion had good water repel en-cy and little effect on the handle and air permeability of cotton fabric.
