摘　　要：以丙烯酸和烷基醇为原料,合成含不同碳链长度的烷基丙烯酸酯软单体,再以含氟丙烯酸酯功能单体和丙烯酸酯软单体为原料进行乳液聚合,得到了稳定性良好的含氟聚丙烯酸酯乳液.研究了含氟聚丙烯酸酯乳液在织物上的应用.采用二浸二轧、110℃预烘1 min、170℃焙烘3 min的整理工艺,整理后棉织物拒水达3~4级,拒油达2级,接触角可达130.4°.Using acrylic and alkanol as raw materials,alkyl acrylate soft monomers with different length of carbon chain were synthesized.With fluorine containing acrylate functional monomers and acrylate soft monomers as materials for emulsion polymerization,the fluorine polyacrylate emulsion with excellent stability was obtained.The application of fluorine polyacrylate emulsion in fabric finishing was investigated.Two dipping and two padding finishing technology was adopted,and the treated fabrics were dryed at 110 ℃ for 1 min,cured at 170 ℃ for 3 min.The water-repellency of the treated fabrics could reach grade 3~4 and oil-repellency could reach grade 2,the contact angle was 130.4°.
