摘要
为了全面、深入介绍水性双组分环氧/胺体系的技术方向和路线,论述了双组分水性环氧/胺体系(Ⅰ型和Ⅱ型)技术的发展历程;概述了Ⅰ型和Ⅱ型体系的固化成膜原理和机理;研究了Ⅰ型和Ⅱ型体系水性环氧树脂与固化剂技术提升思路,如,Ⅰ型环氧树脂的物理改进和化学改进的思路,3类Ⅰ型固化剂的技术发展,Ⅱ型环氧树脂及固化剂的技术发展;介绍了环氧丙烯酸杂化新技术的原理和应用。指出,具有相容性好、涂膜初期耐水性好、与锌粉配伍性好且适用期长、高性价比等性能的环氧树脂/固化剂体系将成为未来的发展方向。
In order to have an in-depth and overall understanding of the technical progress in the waterborne 2K epoxy/amine system, this article describes the development of the typeI and II waterborne 2K epoxy/amine system, summarizes their film-forming mechanism and dis- cusses the improvement of the waterborne 2K epoxy/amine system and curing agent. Specifically, the physical and chemical modification of the type I epoxy resin, the technical pro- gress in type I curing agent and type IIepoxy resin and curing agent have been investigated re- spectively. Meanwhile, the innovative epoxy-acrylic hybrid technology and its application have been introduced. It is revealed that the epoxy/amine system with good initial water resistance, compatibility with zinc flake, long pot life and high cost-effective properties will lead the way.
