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。
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 C 4 H 10 O 2 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 C 4 H 10 O 2 is better,and both two systems have good mechanical properties.
