水性环氧树脂的研究进展

Reasearch progress of water-borne epoxy resin

为了总结和回顾以水作为分散介质或溶剂的水性环氧树脂这一国际上研究的热点,系统地介绍了环氧树脂水性化的方法:机械法,相反转法,固化剂乳化法和化学改性法;总结了国内外水性环氧树脂体系的研究进展,并对其研究前景进行了展望,指出了今后研究的方向:通过寻找新型的固化剂或采用光固化技术来改变涂膜的柔韧性或硬度,改善交联度,缩短固化时间,提高涂层的物理机械性能、光泽度,防止闪锈等.

In order to summarize and review the international research hot point of waterborne epoxy resin in which water was used as disperse medium or solvent.Methods for preparation of waterborne epoxy resin systemicly,including mechanism method,phase inversion technique,firming agent emulsification technique and chemistry modification technique were introduced in this paper.The recent development of waterborne epoxy resin at home and abroad was summarized and its future research was forecasted,and its future research direction was pointed out that the flexibility or solidity of coat and the degree of cross-linking,shorten curing time,raise the function of physical machinery and brilliance,and prevent flash corrosion and so on would be improved by looking for the new type curing agent or using the photocuring technique.
