环氧树脂的固化剂 (Curing Agents for Epoxy Resin)
双酚A缩水甘油醚（DGEBA），是由双酚A和环氧氯丙烷缩聚反应而成，主要在常温下和脂肪胺进行反应，而和芳香胺则反应很慢，需要加热才能固化。 当环氧树脂和过量的多胺（如DETA）反应，消耗了全部环氧基，就形成了含有活泼氢胺基的加成物。 该加成物分子量大，挥发性更低，放热峰更小，而且，其作为固化剂的配比量大，避免了称量造成的误差。 脂肪胺固化剂可以和环氧树脂在常温下实现固化，固化后树脂的性能优异，耐温性可以达到100°C。 和脂肪胺相比，芳香胺固化后的耐温性和耐化性则更高。 环氧-胺固化反应的过程可以下图所示，伯胺中的活泼氢首先和环氧基反应形成仲胺，仲胺进一步和环氧基发生反应。 而形成的叔胺则和环氧基完成聚合反应。
Synthesis and properties of a nonionic water
Water-based epoxy curing agents can be divided into two categories: type I and type II. Type I epoxy systems require their curing agents to have the functions of curing and emulsifying. The epoxy resin is a liquid or emulsion, and the curing agent is a water-soluble amine curing agent.
