摘　　要：通过不饱和脂肪酸和N-(甲氧基甲基)丙烯酰胺(NMMA)与环氧树脂(EP-20)反应得到环氧酯,再将环氧酯与乙烯基类单体采用溶液聚合的方式共聚,制备出多重自交联水性丙烯酸树脂分散体。系统研究了环氧酯和甲基丙烯酸的含量,交联单体NMMA、乙酰乙酸基甲基丙烯酸乙酯(AAEM)、β-明胶蛋白质、不饱和脂肪酸及制备工艺对树脂涂膜综合性能的影响。结果表明:多重自交联水性丙烯酸涂料具备优异的综合性能,表干时间为28 min,耐水性达14 d,硬度和附着力分别为3H和0级,还表现出良好的耐溶剂性。The multiple self-crosslinking waterborne acrylic resin dispersion was prepared by solution polymerization through epoxy ester and vinyl monomer.The used epoxy ester was obtained by the reaction of epoxy resin(EP-20)with unsaturated fatty acid and N-methoxy methacrylamide(NMMA).It was systematically studied for the comprehensive properties of the resin film that was influenced by the proportion of epoxy ester and methacrylic acid,crosslinking monomer NMMA,acetoacetoxyethyl methacrylate(AAEM),β-gelatin protein,unsaturated fatty acid or preparation process.The results showed that multiple self crosslinking waterborne acrylic coatings indicated excellent comprehensive properties,the surface drying time was 28 min,the water resistance was 14 d,the hardness and adhesion were 3H and 0 grade,respectively,and it also exhibited good solvent resistance.
