Description

一种阻燃电缆保护层
技术领域
本发明涉及同轴电缆技术领域，具体涉及一种阻燃电缆保护层。
背景技术
随着社会工业化的不断进步，电力业已成为国民经济快速发展的重要支柱。电线电缆的使用在逐年增加，而随之由于电线电缆造成的火灾也在日益增多。公安部消防局组织编写的《中国消防年鉴》显示，2008年，全国共发生火灾 13.7 万起，其中电气原因引发的火灾4万多起，占29.7% ；2009年，全国共发生火灾12.9万起，其中电气火灾3.9万多起，占30.2% ；2010 年，全国共发生火灾 13.2 万起，其中电气火灾 4.1 万多起，占 31.1%。据统计，造成电气火灾的一大部分原因就是由于电缆阻燃性能不足 ；而电气火灾中造成的人员伤亡多是由于电线电缆燃烧时放出大量烟雾使人窒息而死亡，因此对电线电缆进行阻燃、防火处理就十分重要。
发明内容
本发明要解决的技术问题是提供一种有效阻燃的电缆保护层，以增加电线电缆的耐火性能，减少电缆发生火灾的可能性。
    为解决上述技术问题，本发明涉及一种阻燃电缆保护层，该保护层应用于极细同轴电缆中，包覆在极细同轴电缆的最外层，所述保护层的主要成分及其百分含量配比为：聚乙烯树脂 65%-70%、阻燃母粒10%-15%、氢氧化镁8%-15%，其余为助剂。
优选的，所述保护层的成分中还包括5%-8%无机阻燃填料，所述无机阻燃填料为用阻燃剂处理后的沸石颗粒。
优选的，所述阻燃母粒的制备方法为：按所述阻燃母粒的原料配方，将硅烷改性氢氧化镁、有机改性蒙脱土、钛白粉、相容剂、润滑剂及抗氧剂加入密炼机中，混炼至170℃~180℃，再依次经双螺杆混炼和单螺杆挤出机挤出造粒，制得阻燃母粒，其中，单螺杆加料段温度为145℃ ~155℃，压缩段温度为 170℃ ~180℃，模头温度为 180℃ ~190℃。
优选的，所述助剂包括热稳定剂、增塑剂、抗氧剂和润滑剂。
本发明的有益效果为：提供一种有效阻燃的电缆保护层，通过阻燃母粒和氢氧化镁的配比以增加电线电缆的耐火性能，减少电缆发生火灾的可能性。
