Abstract: The title nonionic waterborne low temperature epoxy curing agent was prepared with polyglycol diglycidyl ether, bisphenol A epoxy resin, aliphatic or aromatic amine. The effect of valieties of amine and the content of polyglycol diglycidyl ether low on the appearance, stability and curing properties of the curing agent was investigated. The film formation process waterborne epoxy system and its pot life, the effect of ratio( hydroxyl group/epoxy group) on film properties was discussed.

Key words: nonionic, low temperature epoxy curing agent, PGDGE, curing dagree

摘要： 采用聚乙二醇二缩水甘油醚、双酚A型环氧树脂、脂肪族多胺或芳香族多胺合成了非离子型低温干固化水性环氧固化剂。研究了采用不同种类的多胺制备的固化剂、聚乙二醇二缩水甘油醚含量对固化剂外观、稳定性及固化性能的影响,研究了水性环氧体系的成膜过程及其活化期,讨论了不同的环氧/胺氢固化比例对最终固化性能的影响。
