Title Study on the preparation of waterborne epoxy resin coating
Abstract
Epoxy resin has good chemical stability and high performance of adhesion, electricity insulating. It is a keystone of every nation how to manufacture the waterborne epoxy resin in waterborne coating’s industry. The preparation of waterborne epoxy resin coating was studied in the paper. Waterborne dispersions of epoxy resin were prepared by the so-called phase-inversion emulsification technique. The influence factors on stable waterborne epoxy resin such as emulsification temperature, HLB, emulsifiers and water content were investigated. High stable epoxy emulsion can be prepared from the choice of optimum emusifiers and technological reactive conditions. The stable epoxy emulsion was used to prepare waterborne epoxy resin coatings afterwards. The influence of curing agent content on coating performance was discussed by testing of the coating, then the optimum content was obtained.

1 绪论
涂料有着悠久的历史，从利用动物的油脂和树上分泌的树脂等为成膜物，发展成为主要以石化产品合成的高分子聚合物为成膜物，人们进行了长期的探索。涂料的生产和使用也是从一种世代相传的技艺发展成为涉及多学科的现代化的涂料工业。随着社会的发展，人们对涂料性能的要求也越来越高，各国也相继出台法规限制VOC（挥发性有机化合物）的排放量。而传统的涂料中含有大量的VOC，因此发展环境友好型的涂料成为涂料领域的研究热点，于是水性环氧树脂涂料就在这种背景下应运而生。
