一种半导电电缆用填充膏及其制备方法
技术领域
本发明涉及电缆填充膏领域,具体涉及一种半导电电缆用填充膏及其制备方法。
背景技术
目前我国线缆行业经济总体实现了持续平稳的增长,中西部地区行业发展进一步加快,为后续行业发展奠定了较好的经济基础。随着电信业发展步伐加快,我国线缆行业五大类产品中的架空导线的需求量与日俱增,其中特种架空导线的需求量也在不断增加,技术要求越来越高。
架空导线防腐脂大多是皂基稠化剂稠化矿物基础油的配方和方法进行生产的,该方法所制备的产品,压力油分离基本都在5%以内,压力油分离没有达到很低的水平,特别是高温稳定性很差,导电系数低,绝缘电阻大。这类产品应用时是将产品填充于导线间隙和表面上的,主要起到长期稳定保护架空导线免于大气腐蚀的防腐和防盐雾性能,同时增加导线的导电率。但是这种架空导线很容易因为电流过大或短路而使导线温度迅速攀升至很高,在这种情况下,按照目前技术制备的填充膏析油量大和高温性能很差,其结果会导致填充膏对导线的保护作用急剧下降,进而影响了导线的整体使用寿命,甚至引起火灾。
目前市场上销售的产品很难满足架空导线高温和导电使用要求,国家标准GB/T36292-2018对架空导线用防腐脂的高温要求以及客户要求分别规定为:1、短期高温稳定性,试验要求规定温度分为三个等级120℃、180℃、280℃;试验时间为1h,在这三个温度环境和时间状态下其油分离应不超过样品重量的0.2%;2、长期高温稳定性,试验要求规定温度分为三个等级120℃、180℃、280℃;试验时间为90d,在这三个温度环境和时间状态下其油分离应不超过样品重量的1.5%;3、填充膏的体积电阻率在23℃环境中要≦1.0×106Ω.cm。
