摘　　要：采用无皂乳液聚合法将甲基丙烯酸十二氟庚酯(RfAA)与丙烯酸十八醇酯(SMA)、丙烯酸羟丙酯(HPAA)按质量比m(RfAA)∶m(SMA)∶m(HPAA)=80∶16.5∶3.5进行乳液共聚,制得了FSH长碳链氟代聚丙烯酸酯三元无规共聚乳液,用红外光谱(IR)对其主组分结构进行了分析,用透射电镜(TEM)、纳米粒度仪对乳液粒子形态、粒径分布进行了表征。结果表明,FSH乳液的乳胶粒呈规则圆球状,平均粒径为109.9 nm。应用研究表明,当FSH乳液的用量为蓝湿革(质量)的6%,pH约为6.0时,处理后的蓝湿革的静态接触角达到了137.6°、拒水等级达到100分、拒油等级达到5级,表现出了良好的拒水拒油效果。In the presence of self-made macromolecule fluorinated surfactant（F-SAa） as emulsifying agent,a fluorinated long alkyl polyacrylate RfAA /SMA/HPAA（FSH） emulsion was prepared in mass ratio of RfAA∶ SMA∶ HPAA =80∶ 16.5∶ 3.5 in aqueous medium.Chemical structure of FSH was characterized by infrared spectrum（IR）,then the particle sizes,particle sizes distribution were investigated by transmission electron microscope（TEM） and other instruments.As a result,FSH emulsion had an average particle size of 109.9 nm.When the dosage of FSH emulsion was 6% and the pH of the solution was about 6.0,the water-and oil-repellency of the treated leather could respectively reach 100 and 5 degree,and the water static contact angle reached 137.6°.
