摘要: 为了研究醇类小分子对环氧/胺体系流变和固化行为的影响,对环氧/胺体系、环氧/胺/小分子醇体系及环氧/胺/咪唑/小分子醇体系进行了DSC、流变及力学性能测试,比较了三个体系的综合性能。实验发现以小分子醇C4H10O2作为功能性组分加入环氧树脂体系中有明显的促进效果,且在咪唑类促进剂2-乙基-4-甲基咪唑存在的情况下,C4H10O2的促进效果更明显,两种体系均具有良好的力学性能。

Abstract: In order to study the effect of micromolecule alcohol on the epoxy/amine system, DSC, rheological and mechanics testing of the epoxy/amine system, epoxy/amine/micromolecule alcohol system, and epoxy/amine/imidazole/small molecule alcohol system were studied in this experiment. The overall performance of the three systems was compared. It is found that the addition of the micromolecular alcohol C4H10O2 as an functional additive into the epoxy resin system has a significant promoting effect. In the presence of the imidazole accelerator 2-ethyl-4-methyl imidazole, the promotion effect of C4H10O2 is better, and both two systems have good mechanical properties.

Key words: epoxy resin, alcohol, rapid curing, curing kinetics, rheological
