| 摘 要： | 采用苯乙烯作为RTM用BMI/DABPA树脂体系的活性稀释剂,对树脂粘度、反应性以及耐热性等方面进行了研究。结果表明,这种活性稀释剂可以极大程度地降低BMI/DABPA树脂的粘度,改善树脂体系的流动性能;由于苯乙烯与BMI/DABPA树脂能发生交联反应,故树脂体系没有低分子挥发物产生,这样在降低树脂体系粘度的同时,兼顾了BMI树脂良好的耐热性能及力学性能。此外,本文还探讨了双马来酰亚胺、二烯丙烯双酚A以及苯乙烯之间的反应机理。实验数据表明,在BMI/DABPA树脂体系中加入25%(W%)的苯乙烯,既可满足RTM用BMI树脂粘度的要求,又可兼顾固化树脂良好的热性能。

| Abstract: | Using styrene as reactive diluent for BMI/DABPA resin was studied in viscosity of the resin,copolymerization of bismaleimide,diallylbisphenol A and styrene,as well as thermal stability of the cured resin,the results show that this reactive diluent not only can reduce the viscosity of resin to meet the need of RTM process,but also has excellent reactivity with BMI/DABPA resin,thus the heat-resistance of the resin is good.This experiment suggests that the 25%(W%) styrene as diluent is prime proportion in BMI ... |
