Description

无卤阻燃光缆护套料
技术领域
本发明涉及光纤护套领域,特别是涉及一种无卤阻燃光缆护套料。
背景技术
光缆由于敷设或使用环境的限制,需要有外防护层,即通常所谓的“护套”。用于生产护套料的聚乙烯(PE)主要有线型低密度聚乙烯、高密度聚乙烯(HDPE)和中密度聚乙烯(MDPE),其中,MDPE的综合性能较好,已成为目前电缆和光缆护套树脂的主流产品。
虽然MDPE材料具有阻燃性好、价廉、挤出工艺好等特点,但由于其含有卤素,燃烧时会放出大量卤化氢气体和浓烟,造成火灾的“二次危害”,从而加大了火灾的损失。尤其是很多科学研究已证实,卤化物对人体健康与环境所造成的损害已愈来愈严重。
发明内容
本发明主要解决的技术问题是提供一种无卤阻燃光缆护套料,具有优异的力学性能、阻燃性能和耐高温老化性能,符合无卤阻燃光缆护套料的技术标准。
为解决上述技术问题,本发明采用的一个技术方案是:提供一种无卤阻燃光缆护套料,其包括如下重量份数的配方组分:聚氨酯弹性体50~60份,硅烷交联聚烯烃弹性体 20~30份,丁腈橡胶20~30份,增塑剂15~25份,阻燃剂25~35份,硫化剂1~3份,促进剂2~5份,补强剂20~30份,填充剂2~5份,稳定剂1~3份,抗氧剂0.5~2份。
在本发明一个较佳实施例中,所述的增塑剂为环氧大豆油。
在本发明一个较佳实施例中,所述的阻燃剂为硼酸锌或Sb2O3
在本发明一个较佳实施例中,所述的促进剂为二硫代氨基甲酸盐类。
在本发明一个较佳实施例中,所述的补强剂为高耐磨炭黑。
在本发明一个较佳实施例中,所述的填充剂为碳酸钙和滑石粉。
在本发明一个较佳实施例中,所述的稳定剂为硬酯酸钙。
在本发明一个较佳实施例中,所述的抗氧剂为对苯二胺。
在本发明一个较佳实施例中,所述的碳酸钙和滑石粉的粒径均为纳米级。
在本发明一个较佳实施例中,所述的碳酸钙和滑石粉的重量配比为1:2~1。
本发明的有益效果是:本发明具有优异的力学性能、阻燃性能和耐高温老化性能,符合无卤阻燃光缆护套料的技术标准;且具有良好的经济和社会效益。
