摘　　要：通过含亲水性氧化乙烯链段的聚乙二醇与环氧基团反应,将聚氧化乙烯链段引入到环氧树脂分子链上,得到含非离子亲水基的水性环氧树脂乳液;采用该乳液与各助剂、颜填料、去离子水等制备了水性环氧防腐涂料,研究了各助剂、防锈颜料及抗闪锈剂对涂料性能的影响,最后制得与基材附着力强,在高湿度环境下施工不出现闪锈,耐水、耐介质和耐盐雾性优异的抗锈蚀水性环氧防腐涂料,改进了水性环氧涂料易起泡、闪锈、防腐期短的问题。The polyethylene oxide segment is introduced into the epoxy resin molecular chain by reacting the polyethylene glycol containing the hydrophilic oxide segment to the epoxy group,and a nonionic hydrophilic epoxy resin emulsion is obtained.Using this emulsion with auxiliary epoxy anti-corrosion coating,waterborne anti-corrosion epoxy coating is prepared,and the effects of each auxiliary,anti-rust pigment and anti-laminar on coating properties are studied.Finally,awaterborne anti-corrosion epoxy coating with strong adhesion to the substrate,no flash rust during construction in a high humidity environment,and with excellent water resistance,medium resistance and salt spray resistance properties was prepared,which solvel the problems of easy foaming,flash rust and short anti-corrosion period of the water-based epoxy coating.
