摘要：

针对长链全氟烷基化合物对环境和人体的危害性,以环境友好的全氟己基乙基丙烯酸酯为功能单体,γ-甲基丙烯酰氧基丙基三甲氧基硅烷为交联单体,采用乳液聚合法制备了4种不同交联剂含量的氟化聚丙烯酸酯乳液,以此替代长链全氟烷基化合物。借助激光粒度仪、傅里叶红外光谱仪、热重分析仪对氟化聚丙烯酸酯乳液结构和性能进行分析。并以棉织物为对象,考察了自交联氟化聚丙烯酸酯乳液的应用性能。结果表明:交联剂的加入可以提高氟化聚丙烯酸酯的热稳定性能;自交联氟化聚丙烯酸酯可在棉织物表面形成完整的拒水膜,其静态接触角可达138.2°;随着交联剂质量分数的增加,整理后棉织物的静态接触角下降至90.6°;当交联剂添加量为1.68 g时,整理棉织物表现出良好的耐洗性能。

Abstract:

In view of the risks of long-chain perfluoroalkyl compounds to the environment and human body, four types of self-crosslinking fluorinated polyacrylates with different crosslinking agent contents were prepared by emulsion polymerization in this research. The long-chain perfluoroalkyl compounds were replaced by using environmentally friendly perfluorohexyl ethyl acrylate as functional monomer and γ-methacryloxypropyltrimethoxysilane as the crosslinking agent. The structure and performance of the self-crosslinking fluorinated polyacrylate emulsions were analyzed using particle size tester, Zeta potential analyzer, Fourier transform infrared spectrum and thermo-gravimetric analysis, and the application performance of self-crosslinking fluorinated polyacrylate emulsions were investigated with on cotton fabrics as the application object. The results show that the addition of crosslinking agent works in improving the thermal stability of fluorinated polyacrylate.Self-crosslinking fluorinated polyacrylate forms a complete water-repellent film on the surface of cotton fabric, and its static contact angle reaches as high as 138.2°. As the content of the crosslinking agent is further increased, the static contact angle of the treated cotton fabric drops to 90.6°.When the amount of crosslinking agent is 1.68 g, the treated cotton fabric demonstrats good washability.

Key words: self-crosslinking, fluorinated polyacrylate, emulsion polymerization, water-repellent finishing, washing resistance, cotton fabric
