Description

一种低烟无卤阻燃聚烯烃电缆料及其制备方法
技术领域
本发明涉及一种环保低烟无卤阻燃聚烯烃电缆料及其制备方法,尤其涉及一种能够通过GA132-1996烟气毒性标准ZA2级的专用阻燃聚烯烃电缆料及其制备方法,属于电线电缆领域。
背景技术
近年来随着世界经济与科技的发展,目前我国电缆厂对低烟无卤阻燃电缆料的需求在数量上有较大增长,对其性能的要求在逐步提高。在新的经济形势与技术条件下,全球电线电缆行业发展呈现新的趋势,环保电缆逐步成为全球电缆的发展重点。同时由于线缆使用的环境多种多样,故有线缆提出了毒性的要求。在Mil-c-24643美国军用船用电缆标准中对电缆的绝缘、填充、护套有燃烧气体毒性指数的要求。为了减少线缆在使用过程中各种情况对环境人体的损害,线缆的毒性研究也是一个必然的发展方向。
针对这些实际使用需求,需要开发一种能够达到ZA2级,且性能稳定性,又不易燃烧,同时能够兼顾满足ROHS和REACH要求的新型电缆料。而现在市场上大多数材料只能满足其中一两项性能要求,无法同时兼顾多项。
发明内容
本发明的目的在于克服现有技术的缺陷,提供一种低烟无卤阻燃聚烯烃电缆料及其制备方法,降低电缆的烟气毒性,且保证该料的各项机械性能。
本发明是通过以下技术方案实现的:
