Abstract

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.

柔性固化剂的合成及性能研究

本文介绍了一种新型柔性环氧固化剂的合成，提出了在不降低树脂固化材料强度和模量的前提下，通过固化提高环氧树脂韧性的方法。结果表明，当柔性固化剂的重量百分比(wt. %)在10% ~ 15%之间时，其韧性达到最大值。当柔性固化剂的加入量为环氧树脂质量的10 wt. %时，树脂的冲击韧性和断裂韧性提高了33%。3%和96。与纯环氧树脂相比，分别降低3%。当环氧树脂中柔性固化剂的添加量为10 wt. %时，材料的冲击韧性为19。5k J·m-2at-50℃时，纯环氧树脂的冲击韧性仅为7。96kj·m-2。
