Description

一种高抗撕通信光缆护套管专用料及其制备方法
技术领域
本发明涉及一种高抗撕通信光缆护套管专用料及其制备方法，属于光缆护套材料领域。
背景技术
通信光缆是由若干根（芯）光纤（一般从几芯到几千芯）构成的缆心和外护层所组成，其传输容量大得多；衰耗少；传输距离长；体积小；重量轻；无电磁干扰；成本低，是当前最有前景的通信传输媒体，广泛地用于电信、电力、广播等各部门的信号传输上，将逐步成为未来通信网络的主体。通信光缆由于敷设或使用环境的限制，需要有外防护层进行保护，即通常所谓的“护套”。目前市场上用于通信光缆护套管的材料存在抗撕裂性差的缺点，在敷设或者安装过程中受到拉拽作用容易断裂，严重影响光纤的传输。因此，急需开发一种高抗撕通信光缆护套管专用料。
发明内容
本发明的目的在于针对现有技术的不足，提供一种高抗撕通信光缆护套管专用料及其制备方法，提高护套管的撕裂强度。
    为实现上述目的，本发明采用的技术方案如下：     一种高抗撕通信光缆护套管专用料，由以下重量份的原料制成：高密度聚乙烯35-55、库马龙树脂22-44、羊毛酸异丙酯3-6、纳米金刚石8-16、肉豆蔻酸钡2-4、聚环氧乙烷4-8、聚烯烃热塑性弹性体15-20、三苯甲烷共聚酯 12-16、玄武岩纤维14-18、双(巯基乙酸异辛酯) 二正辛基锡2-3、氢化霍霍巴油4-7、硼化硅16-22、四硼酸钙10-15、特丁基对苯二酚2-3、2,4,6-丙烯酸三溴苯酯7-11、1,2-环己二醇二缩水甘油醚2-4、2-巯基甲基苯并咪唑1-2、助剂 4-5；
