| 摘 要： | 用自制的一种既含聚醚柔性链段又含苯脂肪氨基刚性链段的端脂肪氨基聚醚(APPEG)作为固化剂对环氧树脂进行增韧改性。扫描电子显微镜和力学性能测试结果表明,固化剂对环氧树脂具有明显的增强、增韧效果,且改性的环氧树脂胶粘剂具有很好的填充性能,填充比高达50%。与羰基铁粉组成的涂层材料具有优异的力学性能和热稳定性能。

| Abstract: | The self-made aralkyl amino-terminated poly(ethylene glycol)(APPEG)containing flexible polyether segment and rigid amino benzene segment was used as curing agent to improve the toughness of epoxy resin.The results of SEM and mechanical measurements showed that the curing agent is effective to improve the epoxy resin and the epoxy adhesive has both high toughness and high strength.Moreover,the carbonyl iron particles have high packed ratio in the modified epoxy resin and there is good compatibility between them.The modified epoxy resin has high filling property and the filling ratio can reach 50%.The coating based on the modified epoxy resin and carbonyl iron powers shows excellent mechanical properties and thermostability. |
