Description
技术领域
本发明属于电缆线材料领域,涉及一种绝缘材料,具体涉及一种抗水树化学交联聚乙烯绝缘料。
背景技术
交联聚乙烯具有绝缘电阻高、介电损耗小、耐溶剂腐蚀、耐老化、价廉易得、寿命长等特点,是目前电线电缆最主要的绝缘材料。目前在我国所制造的交联聚乙烯绝缘料,其配方体系主要为低密度聚乙烯、抗氧剂和过氧化物交联剂组成,一般仅用于35kV以下的电力电缆的绝缘层。
交联聚乙烯电力电缆因为机械和电绝缘性能优异,经济效益高逐渐成为电力电缆的主流,其设计寿命可达30~40年。但是由于制造工艺缺陷,电缆运行环境恶劣以及电缆敷设伤害等,许多电缆内部产生了杂质,气孔等缺陷,这些缺陷在电场、热场、机械应力以及潮湿环境中都会引发局部放电和水树枝现象,从而导致电缆被击穿;水树是影响电缆绝缘性能的主要缺陷之一,普通交联中压及高压电缆在实际运行中受水树作用影响很大。
发明内容
本发明目的是为了克服现有技术的不足而提供一种抗水树化学交联聚乙烯绝缘料。
为达到上述目的,本发明所采用的技术方案为:一种抗水树化学交联聚乙烯绝缘料,它的原料配方包括以下重量份数的组分:
所述聚乙二醇的数均分子量为1×104~5×104,所述弹性体为选自EVA弹性体、POE弹性体和mPE弹性体中的一种或多种。
优化地,所述低密度聚乙烯密度为0.850~0.950g/cm3,熔体流动指数为1.0~3.0g/10min。
优化地,所述抗氧剂为选自4,4’-硫代双(6-叔丁基-3-甲基苯酚)、四[甲基-β-(3,5-二叔丁基-4-羟基苯基)丙酸酯]季戊四醇酯、3,5-双(1,1-二甲基乙基)-4-羟基苯丙酸硫代二-2,1-乙二醇酯和β-(3,5-二叔丁基-4-羟基苯基)丙酸正十八碳醇酯中的一种或几种。
优化地,所述交联剂为选自过氧化二异丙苯和双叔丁基过氧异丙基苯中的一种或几种。
由于上述技术方案运用,本发明与现有技术相比具有下列优点:本发明抗水树化学交联聚乙烯绝缘料,通过向原料配方中加入弹性体和特定分子量的聚乙二醇,这样能够有效改善聚乙二醇与低密度聚乙烯的相容性,使加工性能稳定,制品表面光洁;并且可以吸收并锁住水分,抑制水分在材料中的扩散,增强聚乙烯绝缘材料本身对水树化的抑制性能。
