摘　　要：鉴于使用传统固化剂制备的环氧树脂材料存在力学性能及热性能不佳的问题,使用改性胺类固化剂,可以有效提升环氧树脂体系的综合性能。本文重点对改性胺类固化剂结构及树脂性能提升机理等方面进行了阐述。使用树枝状结构固化剂可以有效提高环氧树脂体系力学性能尤其是树脂韧性;使用苯环改性的固化剂可以很好地提升环氧树脂体系耐热性;而将杂原子改性固化剂引入环氧树脂体系后,树脂在阻燃性大幅提升的同时依旧可以保持较好的力学强度。最后,结合当前环氧树脂使用中的实际问题,对胺类固化剂今后的研究方向进行了展望。The epoxy resin materials prepared with traditional curing agent have problems of poor mechanical and thermal properties.The comprehensive properties of epoxy resin system can be effectively improved by using amine-modified curing agents.Based on the performance improvement of epoxy resin,the structure of amine-modified curing agent and the mechanism of resin performance improvement were explored.The use of dendritic structure curing agent can effectively improve the mechanical properties of epoxy resin systems,especially the toughness of resin.The heat resistance of epoxy resin system can be improved by using benzene�modified curing agent.After introducing heteratomic-modified curing agent into the epoxy resin system,the resin can still maintain good mechanical strength while the flame retardancy is greatly improved.Finally,the research direction of amine-containing curing agent in the future is speculated based on the practical problems in the application of epoxy resin.
