| 摘 要： | 采用双邻苯二甲腈树脂(BAPh)对环氧树脂E-44(EP)进行改性,同时制备了BAPh/EP/玻纤复合材料。采用示差扫描量热仪,热重分析,力学性能测试及氧指数仪研究了改性树脂的热性能、力学性能及阻燃性能,并对BAPh/EP/玻纤复合材料的力学性能进行了表征。结果表明,当BAPh质量分数达到50%时,改性树脂固化物在空气中的起始分解温度达到377.6℃,比纯环氧提高74.3℃,氧指数达到34.5%,复合材料的弯曲性能指标达到最大,添加双邻苯二甲腈后环氧树脂的耐热性、力学性能和阻燃性能得到了明显改善。

| Abstract: | Epoxy resin was modified by 2,2-bis4-(3,4-dicyanophenoxy) phenyl] propane(BAPh).The heat resistance,mechanical properties and flame retardance of the modified resins were investigated by DSC,TGA,mechanical property test and oxygen index tester.The the initial decomposition temperature in the air of the modified resin cured products with 50% mass fraction of BAPh was 377.6 ℃ and higer 74.3 ℃ than that of pure epoxy and the oxygen index was 34.5%.The bending performance of the composite materials reached the maximum.The heat resistance,mechanical properties and flame retardance of the epoxy resins adding phthalonitrile were significantly improved. |
