Abstract

Imidazole cured epoxy resin systems were evaluated for one-component, fast-curing resins for liquid molding of automotive composite parts according to industry requirements. It was demonstrated that an epoxy resin-1-(cyanoethyl)-2-ethyl-4-methylimidazol(EP-1C2E4MIM) system would cure in a few minutes at 120 °C, while exhibiting acceptable pot life, viscosity profiles, and low water absorption. Moreover, this system yielded high parts with mechanical properties similar to the amine-epoxy systems, which are the mainstream two-component epoxy resin systems for automobiles.

摘要

根据行业要求，对用于汽车复合材料部件液体成型的单组分快速固化咪唑固化环氧树脂体系进行了评估。结果表明，环氧树脂-1-(氰乙基)-2-乙基-4-甲基咪唑(EP-1C2E4MIM)体系在120℃下几分钟内即可固化，同时具有可接受的适用期、粘度曲线和低吸水性。此外，该体系所制得的部件具有较高的机械性能，与汽车主流双组分环氧树脂体系胺-环氧树脂体系相似。
