摘　　要：以丙烯酸全氟烷基酯(Zonyl TM)为功能单体,阴离子、非离子乳化剂为复合乳化剂,采用预乳化半连续乳液聚合法合成了氟改性羟基丙烯酸乳液,并将合成的乳液与氨基树脂制得性能优异的丙烯酸氨基清漆。系统地研究了氟单体、交联单体、丙烯酸含量及苯乙烯和甲基丙烯酸甲酯的配比等因素对涂膜性能的影响,对影响清漆的混容性及贮存稳定性的各因素进行了讨论。此外,含氟乳胶膜对水的接触角及红外光谱表征结果表明,Zonyl TM有效参与了共聚反应,提高了涂膜的耐水性及耐化学品性。Fluoroacrylate modified hydroxyl acrylic emulsion was synthesized by pre -emulsion and semi - continuous emulsion polymerization, with perfluoroalky acrylate （Zonyl TM） as functional monomer, and a mixture of anionic and nonionic emulsifier as emulsifier, which was then used together with melamine resin to give high performance acrylic -melamine varnish. The effects of fluorine -containing monomer, crosslinking monomer, acrylic acid amount and the ratio of styrene and methyl methacrylate on the film per- formance were systematically investigated. And the factors influencing the compatibility and storage stability of varnish were discussed. Additionally, water contact and the FF - IR of the fluorine - containing emulsion film were analyzed. The results showed that Zonyl TM was effectively involved in the copolymerization and improved the water resistance and chemical resistance of the film.
