Description
技术领域
本发明属于电缆材料领域,具体涉及一种电线电缆用阻燃护套料及其制备方法。
背景技术
PVC护套具有柔软、随意弯曲折叠、相对厚度薄、体积小、连接简单、拆卸方便等优点,可以任意选择导线数目及间距,使联线更方便,大大减少产品的体积,减少生产成本,提高生产效率,适合电器设备中作数据传输线缆或动力传输之用。而传统的PVC电缆护套由于自身配料不合理,致使制造成的护套抗拉强度较低,韧性差,在实际的使用过程中难免会将电缆弯曲或者扯拉,这样极易造成护套的破裂,无法继续对包裹在护套内部的电缆导体起到保护作用,使用寿命较短;电力电缆使用时一般都会在外层增加阻燃护套料,以防止电缆在积聚大量热量而发生火灾,而正是物料燃烧时产生的烟,这些烟不但产生大量的有毒物质,而且可以导致人窒息,这才是因火灾而死亡的主要因素,因此研究具有良好阻燃性能的电缆保护套是防止电力电缆火灾的重要课题。
