环氧树脂具有耐腐蚀、附着力强、电绝缘性能良好等优异的特性,因此广泛应用于国防和国民经济的各个领域。国内最早的环氧树脂固化剂为胺类固化剂,常用的乙二胺虽具有常温固化、混合方便,但毒性较大,固化受温度和湿度影响,环氧固化后的综合性能也不够理想。七十年代我国环氧固化剂出现 Epoxy resin with excellent corrosion resistance, strong adhesion, good electrical insulation and other characteristics, it is widely used in national defense and national economy in all fields. The earliest epoxy curing agent for the amine curing agent, although commonly used ethylenediamine curing at room temperature, mixing convenience, but toxicity, curing temperature and humidity, the overall performance of epoxy curing is not ideal. Seventies China epoxy curing agent appears
