【摘要】 讨论了苯乙烯用量对顺丁烯二酸酐固化环氧树脂复合材料性能的影响。结果表明 ,苯乙烯能有效改善环氧树脂复合材料的性能。当苯乙烯添加量在 10～ 12份之间时 ,弯曲强度为未加苯乙烯的 1 45倍 ,冲击强度为 1 66倍 ,马丁耐热为 1 0 5倍 ,绝缘性能变化不大。差热分析和红外光谱分析表明 ,顺酐与环氧发生固化反应的同时 ,苯乙烯与顺酐中的不饱和双键进行了自由基交联共聚反应更多还原

【Abstract】 The property of maleic anhydride curied epoxy resin composite with different compounding ratio of styrene was dis cussed The results showed that the property of the expoxy resin composite could be improved by styrene obviously When the content of styrene was 10 PHR～12 PHR,the bend strength of the composite was 1 45 times of that of the epoxy resin,the impact strength and Martin heat resistant were 1 66 times and 1 05 times as much as those of the resin respectively,with little change of the dielectric properties DTA and IR analyses of the composite indicated that crosslinking reaction between styrene and maleic anhydride might occur during the curing process更多还原
