Description

一种铁路车辆电缆用绝缘材料
技术领域
本发明属于电缆领域,具体是一种铁路车辆电缆用绝缘材料。
背景技术
随着中国铁路的高速发展,现代化车厢以安全度和人性化设计为前提,这些条件和设施,必不可少地与电力、控制和信号电缆有关,各类电线电缆除应保证运行安全可靠外,还应考虑到事故情况下尽量避免对人身伤害和减少对设施的影响。
绝缘材料在使用一年的年限以后,绝缘性能都会呈现一定程度的劣化,也就是绝缘老化,绝缘材料的老化原因是多样的、复杂的,最具代表性的主要有热老化、机械老化、电压老化等。绝缘材料老化的表现主要有绝缘电阻下降,介质损耗增大等。
现有的电缆绝缘和护套品种比较少,客观上限制了铁路车辆电缆的应用和推广。用传统高分子材料制成的电线电缆的绝缘层或护套,在使用过程中很容易因线路发热量过大或短路等原因而燃烧,引起火灾。

所述抗氧剂为四(β-(3,5-二叔丁基-4-羟基苯基)丙酸)季戊四醇酯、三(2,4-二叔丁基苯基)亚磷酸酯中的一种。
所述聚丙烯是熔融指数大于3g/10min的均聚或共聚聚丙烯。
所述相容剂为马来酸酐与聚丙烯的接枝物,接枝率在0.7-1.0%之间。
本发明的有益效果:本发明以丁腈橡胶、三元乙丙橡胶、聚丙烯为主料,加入相容剂和钙锌复合稳定剂,制得绝缘材料具有很好的化学稳定性;抗氧剂和防老剂使得绝缘材料具有很好的耐热老化性能、耐臭氧;本发明铁路车辆电缆用绝缘材料具有耐高低温阻燃性,绝缘性能好,机械强度高的优点。
