摘　　要：为制备耐水洗性能优良的三防整理剂,以丙烯酸十三氟辛酯(Tridecooctyl acrylate,C6F)和丙烯酸十八酯(Octaglycidyl acrylate,SA)为主要单体,甲基丙烯酸缩水甘油酯(Glycidyl methacrylate,GMA)为交联单体,通过细乳液聚合法制备了一种短链含氟丙烯酸酯共聚物细乳液,并将其作为整理剂应用在棉织物上;通过红外光谱分析、粒径分析和热重分析对乳液进行表征,采用场扫描电镜和X射线光电子能谱仪对棉织物表面结构进行分析,探究C6F和SA的用量对该共聚物薄膜表面能的影响。结果表明:当C6F质量分数为50%,SA质量分数为25%时,共聚物薄膜的表面能低至9.16mN/m;整理后棉织物的水接触角为150.8°,橄榄油接触角为141.2°,拒水等级4级,拒油等级4级,耐沾污等级5级;整理后棉织物经过20次水洗后水接触角仍有135.7°,橄榄油接触角为124.8°,表现出良好的耐水洗性能。该文可为制备短链C6型含氟丙烯酸酯共聚物提供数据参考。To prepare a three-proof finishing agent with good water-resistant properties,a short chain fluorinated polyacrylate miniemulsion was prepared by miniemulsion polymerization with tridecooctyl acrylate(C6F)and octaglycidyl acrylate(SA)as main monomers and glycidyl methacrylate(GMA)as crosslinked monomer,and was applied as a finishing agent on cotton fabrics.The emulsion was characterized by infrared spectrum analysis,particle size analysis and thermogravimetric analysis,and the surface structure of cotton fabrics was characterized by scanning electron microscopy(SEM)and X-ray photoelectron spectroscopy(XPS).The influence of the amount of C6Fand SA on the surface energy of this copolymer film was investigated.The results showed that the surface energy of the copolymer film was 9.16mN/m when the mass fraction of C6Fwas 50%and the mass fraction of SA was 25%.The finishing cotton fabric had a water contact angle of 150.8°,an olive oil contact angle of 141.2°,a water repellency class 4,an oil repellency class 4and a stain resistance class 5.After 20washes,the water contact angle of the finished cotton fabric was still 135.7°,and the olive oil contact angle was 124.8°,demonstrating good water washing resistance.The results can provide data reference for the preparation of short chain C6fluorinated acrylate copolymer.
