摘要:
研究自由基接枝法在环氧树脂中引入丙烯酸树脂，使环氧树脂具有自乳化性能.对溶剂种类、丙烯酸酯类单体的用量及配比、引发剂的用量、接枝反应温度及中和度对接枝共聚物水分散性和储存稳定性的影响进行了研究.结果表明：当甲基丙烯酸用量为环氧树脂质量的15%，引发剂的用量为单体总质量的4%，接枝反应温度为80 ℃，甲基丙烯酸（MAA）、丙烯酸丁酯（BA）和苯乙烯（ST）的质量配比为122，中和度为60%，溶剂选用丙二醇单甲醚和丙酮的混合溶剂时所得到的乳液为带明显蓝光的白色均匀乳液.用咪唑作固化剂时，漆膜的硬度、附着力和柔韧性优异，且漆膜无色透明.
Abstract:
Through the graft copolymerization of acrylic ester class monomers monomer with epoxy with epoxy resin, the strongly hydrophilic groups of —COOH was introduced into the epoxy resin and waterborne epoxy resin was prepared. The paper researches the influence of solvent kinds, used amount of MAA, the mass proportion among MAA, BA and ST, used amount of BPO, graft copolymerization and neutral degree on disperision in water and storage stability of obtained. The results showed that, when the use amount of MAA was 15% of the mass of epoxy resin, the use amount of BPO was 4% of the total mass of MAA, ST and BA, graft copolymerization temperature was 80 ℃, the mass proportion among MAA,ST and BA was 122, neutral degree was 60% and PGME and acetone as mix solvent, we got white and welldistributed waterborne epoxy resin with obviously blue light. After curing, colorless and crystal coating with good hardness and adhesion were obtained.
