背景技术
电线(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。电线有电力电线、控制电线、补偿电线、屏蔽电线、高温电线、计算机电线、信号电线、同轴电线、耐火电线、船用电线、矿用电线、铝合金电线等等。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。
电线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线料,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的绝缘和护层材料。但是目前市场上的电线料仍然存在缺陷,有的防潮效果差,容易发生漏电,有的防霉抗菌效果不好,不能长时间应用到湿热环境中,而且人们在使用电线时,非常容易感染霉菌,影响人们的健康。
