Description
技术领域
本发明涉及一种电缆料的组分,尤其是一种柔软型高伸长率的环保聚烯烃电缆料,属于电缆技术领域。
背景技术
电线电缆绝缘及护套用塑料俗称电缆料,其中包括了橡胶、塑料、尼龙等多种品种。电缆料生产企业是以电缆生产企业为用户,只要有电线电缆需求就有电缆料的市场。电线电缆产品中除钢芯铝绞线、电磁线等裸线产品外几乎都需要绝缘层口。目前我国有电线电缆生产企业近5000家,又有城乡电网改造、西部大开发及通信设施大面积升级改造对电线电缆产品的巨大需求,因而从一段时间来看,电缆料在我国具有广泛的市场发展前景。
中国专利申请“一种pvc电缆料”(申请号为:201610852047.X,申请人为:青岛九洲千和机械有限公司,申请日:2016年09月26日,公布日为:2018年04月03日),,其创新点在于:按质量份数该高分子材料有以下组分构成:pvc树脂为100重量份;增塑剂:50-55重量份;热稳定剂:6-8重量份;阻燃抑烟剂:20-30重量份;填料:10-20重量份。本发明中增塑剂要求具有更高耐热性、
低挥发性、分子量较大,此类增塑剂有偏苯三酸三辛酯(TOTM)、均苯四酸四辛酯(TOPM)、双季戊四醇酯、聚酯等。本发明选择的增塑剂为偏苯三酸三辛酯和双十三酯;热稳定剂为铅盐热稳定剂;阻燃抑烟剂为Sb 2O3、硼酸锌、氢氧化铝、氢氧化镁,Sb 2O3为3重量份,硼酸锌为4重量份,氢氧化铝和氢氧化镁为30重量份。
上述专利申请虽然也达到了一定的阻燃抑烟的效果,但随着电线电缆工业的发展,人们对线缆产品提出了更高更严格的性能要求。电缆用绝缘料一般要求必须具有优良的耐长期热老化性能、耐辐照、电气性能稳定、阻燃性能及绝缘性能优等特点。
