Description

废弃电解液在外护套制备领域的应用
技术领域
本发明属于电缆领域，具体涉及一种废弃电解液在外护套制备领域的应用。
背景技术
当今社会电力的应用遍布全球各行各业，世界对电力的需求也在逐年增加，正因如此每年因电而引起的火灾也是不断增加，尤其是在一些公共场所，例如：大型商场、医院、车站等人口密集区域。2005年12月15日，吉林省辽源市中心医院刚装修后不久发生重大火灾事故，造成37人死亡，95人受伤。事故直接原因是配电室使用电缆不阻燃，发生短路故障后，引燃可燃物。
由于采用普通的电线电缆一但发生火灾，会引起电缆燃烧，或者其他电缆运行故障，将导致各正常运作的设备停止运作，同时浓烟滚滚，透光率瞬间下降，一方面会造成设备的损坏，另一方面因浓烟和指示灯没有电力供应而失去指示作用，导致被困人员无法找到逃生出口，会造成人员因吸入大量烟尘诱发疾病，严重的会因窒息而亡，同时在没有灯光照射的条件下救援人员无法确定财物及被困人员的具体位置，导致救援滞后，从而造成大量的财产损失和人员伤亡。
发明内容
本发明的目的在于提供一种废弃电解液在外护套制备领域的应用。
本发明为实现上述目的，采用以下技术方案：
一种废弃电解液在外护套制备领域的应用：
(1)熔融共混：将聚烯烃、草木灰、硅烷偶联剂、硬脂酸、电解锌酸浸渣按照上述比例混合，以600r/min的速度搅拌10min，然后在170℃下熔融共混10min，得到胶料；
(2)交联：将步骤(1)所得的胶料在170℃下交联30min后，再按照所述比例加入树胶和白炭黑，反应10min，得到混合料；
(3)造粒：将步骤(2)所得的混合料加入到双螺杆挤出机中进行共混挤出，然后进行造粒，得到颗粒料；
(4)制备护套管：将步骤(3)中所得的颗粒料加入到基础成型机中进行成型、定径、牵引、切割后，得到外套管；
5)制备电缆：将步骤(4)所得的外套管用于电缆的最外层，得到废弃电解液在外护套制备领域的应用。
所述的电缆线包括导体，所述的导体从内到外依次套接有绝缘层、屏蔽层、中被层、防水层、防火耐高温层和外护套；
与现有技术相比，本发明的有益效果是：
本申请所得的电缆线的外护层拉伸强度在26MPa以上，断裂伸长率在750％以上，氧指数在36以上，阻燃性能达到A级，兼具显著的显著的强度高阻燃性能强的特点；同时，回收利用了草木灰和电解锌酸浸渣，减少了环境污染同事降低了生产成本，具有显著的经济效益和环保效益。
