丁腈橡胶/聚氯乙烯/受阻酚AO-60共混物的结构与性能

向平  赵秀英  张立群 

摘 要:用差示扫描量热法、X射线衍射法、扫描电子显微镜及元素分析法分析了丁腈橡胶(NBR)/聚氯乙烯(PVC)/四[β-(3,5-二叔丁基-4-羟基苯基)丙酸]季戊四醇酯(AO-60)共混物的结构,并研究了共混物的阻尼性能及力学性能.结果表明,当AO-60用量小于50份时,其分子在基体中以非晶态形式存在;当AO-60用量超过50份时,过量的AO-60形成聚集体并在基体中形成少量的晶体;NBR/PVC/AO-60共混物内部呈现"海相-岛相"结构,连续相主要是NBR,而分散相主要是PVC与AO-60分子.NBR/PVC/AO-60共混物的损耗因子-温度曲线呈双峰特征,且随着AO-60用量的增加,峰值明显增大.当AO-60用量为50份时,NBR/PVC/AO-60共混物的综合力学性能较佳.
