| 摘 要： | 采用细乳液聚合法制备了环氧丙烯酸酯复合乳液，考察了固化温度、固化时间及磷酸酯乳化剂含量对环氧丙烯酸酯复合涂膜性能的影响，结果表明环氧丙烯酸酯复合乳胶粒子呈均匀的球形结构，且平均粒径分布在150 nm左右。当固化温度为120℃、固化时间为2 h、磷酸酯乳化剂含量为3%时，涂层的耐腐蚀性较好。研究了复合乳液的成膜过程和防腐蚀机理，通过复合乳液与金属底材形成致密的钝化膜，阻隔水分子和无机离子的浸入，提高了涂层的防腐性能。

| Abstract: | Epoxy acrylate composite latex was prepared via miniemulsion polymerization. The effects of curing temperature, curing time and content of phosphate ester emulsifier on the properties of epoxy acrylate composite coating were investigated. The results showed that the epoxy acrylate composite latex particles were uniform spherical structure, and the average particle size distribution was about 150 nm. When the curing temperature is 120℃, the curing time 2 h, the content of phosphate ester emulsifier 3%, the coating has the best corrosion resistance. The film formation and mechanism of corrosion resistance were researched. The passivation film was formed between the composite latex and metal substrate and the corrosion resistance of obtained coatings was improved. |
