摘　　要：以水性聚氨酯作为种子乳液,与含全氟己基乙基丙烯酸酯(C6F)、丙烯酸羟丙酯(HPAA)、甲基丙烯酸十八酯(SMA)、苯乙烯(ST)等进行乳液聚合,制得了含氟聚丙烯酸酯-聚氨酯复合乳液(WPUAF)。通过红外光谱、纳米粒度仪、场发射扫描电镜(FE-SEM)等对WPUAF的结构、粒径、成膜形貌以及应用性能进行研究。结果表明,WPUAF能在纤维表面形成一层致密的疏水膜;在WPUAF的用量为3 g/100 g H2O,并在100℃烘焙5 min、180℃定型2 min的工艺条件下,整理后的织物与水的接触角达到136.9°,疏油等级为6级。The fluorinated polyacrylate-polyurethane emulsion （WPUAF）was prepared by emulsion polymeriza- tion with 2-（ perfluorohexy ） ethyl acrylate （ CrF ）, octadecyl methacrylate （ SMA ）, 2-hydroxypropyl acrylate （HPAA）, styrene（ST） and the seeding emulsion of waterborne polyurethane. The structure, film morphology and application performance of WPUAF were studied by infrared spectroscopy, nanoparticle size analyzerand field spec- trum scanning electron microscopy （FE-SEM） , etc. The result showed that WPUAF formed dense membrane which was hydrophobic on the surface of fiber. The dried fabric samples was submerged into 3 % solution of WPUAF in H20 ,then dried at 100 ℃ during 5 min and finalized the design at 180 ℃ for 2 rain. The water contact angle of fabric was 136.9° with the oil-repellent grade 6.
