摘要

采用γ射线辐照引发丙烯酸六氟丁酯和甲基丙烯酸十二氟庚酯进行乳液聚合，成功制备了具有防水防油功能的含氟织物整理剂。分别用傅立叶红外、动态光散射纳米粒度分析仪、透射电镜对产物化学组分、乳胶粒子尺寸和微观形貌进行了表征。研究了辐照剂量、乳化剂和单体种类对产品制备及性能的影响。结果表明，当辐照剂量为5kGy时，甲基丙烯酸十二氟庚酯的转化率达到98%，而丙烯酸六氟丁酯的转化率为76%；当剂量为10kGy时，丙烯酸六氟丁酯单体可聚合完全。经甲基丙烯酸十二氟庚酯聚合物乳液处理的织物表面拒水性能达到六级、拒油性能达到三级。

Abstract

Fluorocarbon finishing agents were prepared by γ-ray initiated emulsion polymerization of fluorine-containing acrylates at different doses. Copolymerization of the fluorocarbon monomer and butyl acrylate was also studied. Morphology and size distribution of the emulsion particles were investigated by transmission electron microscopy and dynamic light scattering, respectively. Influence of fluorine-containing monomer on water and oil repellency property of final products was discussed. It was found that conversion of the dodecafluoroheptyl methacrylate was 98% at 5kGy and hexafluorobutyl acrylate was fully polymerized at 10kGy. Water repellency of the emulsion product derived from dodecafluoroheptyl methacrylate was Grade six and the oil repellency was Grade three.
