Description

一种双层共挤绝缘LED紫外光交联彩色低烟无卤阻燃电缆料及其制备方法 技术领域
本发明涉及辐照交联双层共挤电缆料领域，更具体是涉及一种双层共挤绝缘LED紫外光交联彩色低烟无卤阻燃电缆料及其制备方法。
背景技术
随着时代的进步与发展，家用电器的功率和品种不断增加，电线超负荷运行常态化，传统的PVC布电线由于受限于当时的技术、工艺、材料等因素，其耐温等级低、使用寿命短仅25年，而新型的单层低烟无卤绝缘材料使用的无卤阻燃剂极易吸潮，导致其绝缘电阻下降。
房屋建筑电线的安全性关系到每个人的生命安全，随着城市房屋建筑高层化发展速度较快，建筑用布电线和建筑物使用寿命同步是发展大趋势，相对于70年的房屋产权，电线只有25年寿命显然远远不达标。由于电线绝缘层在正常运行中会发生热作用，导致绝缘材料发生热氧化裂解，最终老化并引发漏电、火灾等安全事故，由于电缆价格较高，中途换线对建筑结构会造成损坏，房屋和道路下的供电线缆被过度使用的情况不在少数，实现电线的 长寿命已经迫在眉睫。
因此，如何提供一种使用寿命长并且性能优异的双层共挤绝缘LED紫外光交联彩色低烟无卤阻燃电缆料是本领域技术人员亟需解决的问题。
