一种具备防霉防潮抗菌功能电缆料的制备工艺
技术领域
本发明属于电力电缆材料加工领域,具体涉及一种具备防霉防潮抗菌功能电缆料的制备工艺。
背景技术
电缆(electric cable;power cable)通常是由几根或几组导线(每组至少两根)围绕一根中心绞合而成,其形状类似绳索,同时外层覆盖高度绝缘层。电缆有电力电缆、控制电缆、补偿电缆、屏蔽电缆、高温电缆、计算机电缆、信号电缆、同轴电缆、耐火电缆、船用电缆、矿用电缆、铝合金电缆等等。它们都是由单股或多股导线和绝缘层组成,用来连接电路、电器等。
电缆绝缘外层主要用于保护内层导线,目前大多采用聚氯乙烯电缆料,它是以PVC树脂为基础,加入各种配合剂的多组份混合材料。由于它机械性能优越、耐气候性好、有优良的电气绝缘性能、加工容易和成本低廉等优点,因此被广泛用于电线电缆的绝缘和护层材料。但是目前市场上的电缆料仍然存在缺陷,有的防潮效果差,容易发生漏电,有的防霉抗菌效果不好,不能应用到湿热环境中,而且人们在使用电缆时,非常容易感染霉菌,影响人们的健康。
发明内容
