Description

一种高阻燃低烟无卤电缆料
技术领域
本发明涉及电缆料领域，确切地说是一种高阻燃低烟无卤电缆料。
背景技术
电线电缆专用树脂包括电缆绝缘料和电缆护套料，所用原料主要有聚乙烯和聚氯乙烯。现在，国内6 kV级以上电力电缆已全部采用聚乙烯交联绝缘料;1 kV以下的低压电缆则以聚氯乙烯绝缘和聚氯乙烯护套为主，但由于聚氯乙烯稳定性及电绝缘性较差，因此，正在愈来愈多地被聚乙烯取代;通讯电缆一般以高密度聚乙烯做绝缘层，以线性低密度聚乙烯做护套层;光缆则主要是用高密度聚乙烯和中密度聚乙烯做为护套料。
发明内容
本发明的目的在于提供一种高阻燃低烟无卤电缆料。
上述目的通过以下方案实现：
一种高阻燃低烟无卤电缆料，其特征在于：其是由下述重量份的原料制得：高密度聚乙烯HDPE 100-110、高岭土20-30、明矾1.5-2.8、聚磷酸铵0.8-0.9、纳米碳酸钙粉1-2、改性凹凸棒土35-50、硅烷偶联剂KH550  1-2.5、钛白粉1-2、硬酯酸钙 0.5-0.8、十溴二苯乙烷1-2、三氧化二锑1.5-3、硼酸锌2.5-4、对苯二甲酸酯1-2、甲基氢醌0.8-1；
改性凹凸棒土的制备方法是将凹凸棒土在500-550℃下煅烧4-5小时，然后，取出，与相当于凹凸棒土重量2-4%的氢氧化铝一并加入适量水中研磨，加10-15%盐酸溶液调PH为4-5，研磨浆料至400-500目后，再加氢氧化钠调为中性，喷雾干燥，得粉末；将所得粉末与相当于凹凸棒土重量2-4%的柠檬酸三丁酯混合均匀即得。
所述的一种高阻燃低烟无卤电缆料，其特征在于：
  制备方法为：
　　（1）取高密度聚乙烯HDPE 、聚磷酸铵、偶联剂KH550、钛白粉、十溴二苯乙烷按重量份混匀，于捏合机中120-128℃下捏合7-9分钟后，取出冷却；
　　（2）将步骤（1）所得冷却后的物料与剩余各原料混匀，于双螺杆挤出机中混炼、造粒，控制温度在128-130℃，得到成品。
本发明的有益效果为：本发明制备方法简单，操作方便，组成原料配方合理，制得的电缆料具有机械性能高、耐高温、阻燃性能高，燃烧时低烟无毒。
