Synthesis and Properties of a Flexible Curing Agent
This paper presents the synthesis of a new type of flexible epoxy curing agent and an approach to improve the toughness of epoxy resin by curing without reducing the strength and modulus of the resin-cured material.The results show that the degree of toughness reaches maximum values when the flexible curing agent is applied at weight percentages( wt. %) between 10% and 15%. When the amount of flexible curing agent added to epoxy resin weight is 10 wt. %,the impact toughness and fracture toughness increases by 33. 3% and 96. 3%,respectively,compared with the pure epoxy resin. When the amount of flexible curing agent added to epoxy is 10 wt. %,the resulting impact toughness of the material is 19. 5k J·m-2at-50℃,the impact toughness of pure epoxy resin is only7. 96 k J·m-2.
