摘要

固化剂结构对环氧树脂的固化行为和固化物性能具有重要影响，本文研究了聚醚胺（D230）、异佛尔酮二胺(IPDA)和3

3′-二甲基-4

4′-二氨基二环己基甲烷（DMDC）3种胺类固化剂与实验室自制的低黏度环氧树脂A进行固化反应。通过黏度分析、红外（FTIR）光谱分析、DSC分析等手段研究了环氧树脂与固化剂反应程度随固化时间和固化温度的变化规律，采用万能材料试验机研究了固化温度对固化物拉伸强度、断裂伸长率的影响。结果表明，3种树脂/固化剂体系的固化反应活化能分别为59.6、50.9、54.9 kJ·mol-1；与脂肪族固化剂D230相比，脂环族固化剂IPDA和DMDC具有反应活性高，同样固化条件下固化产物的固化程度高、强度高和断裂伸长率高的特点，并且双环结构的DMDC具有更高的韧性。

Abstract

The structure of curing agents has an significant impact on curing behavior of epoxy resin and properties of cured compounds.Three amine curing agents

polyether amine(D230)

alicyclic amine isophorone diamine(IPDA)

3′-dimethyl4

4′-diaminodicyclohexyl methane(DMDC)were used for curing a selfmade low viscosity epoxy resin A.The curing process of the epoxy resin system cured with the curing agent under different curing times and curing temperatures were monitored by viscosity analysis

infrared(FTIR)spectroscopy

and differential scanning calorimetry analysis(DSC).The influence of curing temperature on tensile strength and elongation was investigated by universal testing machine.The results showed that curing reaction activation energy(Ea)of the three epoxy resin/hardener systems were 59.6 kJ·mol-1，50.9 kJ·mol-1 and 54.9 kJ·mol-1

respectively.Compared with aliphatic amine curing agent D230

the products cured with alicyclic curing agents IPDA and DMDC showed higher reaction activity and could result in higher degree of curing

higher tensile strength and greater elongation. Furthermore

curing agent DMDC with bicyclic structure could provide even more excellent toughness.
