| 摘 要： | 以聚丙二醇和环氧氯丙烷为原料合成出了低黏度的脂肪族环氧树脂。使用上述环氧树脂与双酚A型环氧树脂按不同的比例混合后,再加入大分子胺类固化剂,由此构筑出环氧树脂固化体系并对其黏度、凝胶时间和固化物的力学性能进行了表征。结果显示,该环氧树脂固化体系在常温下具有很低的黏度与较长的凝胶时间,其固化物的拉伸与弯曲性能较好,且冲击韧性有了明显的改善。

| Abstract: | A aliphatic epoxy(AEP) resin with low viscosity was synthesized by the reaction of polypropylene glycol 1000 and epichlorohydrin.The AEP was mixed with the bisphenol A epoxy resin,and then the resulting epoxy resin system was cured with the polymeric amine curing agent.The effect of AEP content on gel time of the epoxy resin system was studied and the mechanical properties of the cured resin containing AEP were also discussed.It showed that the epoxy resin system had very low viscosity and longer gel time a... |
