摘　　要：本文通过异氰酸酯键将多羟基丙烯酸酯共聚物与含羧基化合物以及丙烯酸酯基键接,合成了一种可聚合型的乳化剂M。并将该反应型乳化剂高速乳化丙烯酸酯树脂和单体的组成物,制备了一种水性UV乳液。考察了乳化剂M含量、搅拌速度对乳液性能的影响,并测试了该乳液制备的不锈钢保护油墨,结果表明此油墨具有良好的耐水性,优异的附着力,良好的耐切削液性能以及较快碱液退膜性。A polymerizable emulsifier M was synthesized by bonding polyhydroxy acrylate copolymers with carboxyl compounds and acrylate groups through isocyanate bonds.A waterborne UV-curable emulsion was prepared by high speed stirring acrylic resin and monomer mixture with reactive emulsifier.The effects of emulsifier content and stirring speed on the performance of the emulsion were investigated,and the stainless steel protective ink prepared with the emulsion was tested.The results showed that the ink possessed good water resistance,excellent adhesion and anti-cutting fluid and could quickly remove ink speed in alkali solution.
