Description

一种轻质高压气体阻燃电缆用填充
技术领域
本发明涉及电缆技术领域,尤其涉及一种轻质高压气体阻燃电缆用填充。
背景技术
电缆填充用于填充电缆中的缝隙,目前电缆用填充大多采用PP绳、无机绳、(橡皮、塑料)垫芯条。由于现在多数填充密度大,其制作成本较高,且会导致电缆质量较重,会对电缆的使用造成不良影响,特别是在般天、船舶、武器装备等用电缆有严格的重量要求的场合,不仅如此,现在大多填充没有阻燃效果,且填充(特别是阻燃填充)大多可变形性差,无法填满缝隙,导致电缆外形不圆整,影响美观和使用。
发明内容
本发明的目的是为了解决现有技术中电缆填充质量重、阻燃性差的问题,而提出的一种轻质高压气体阻燃电缆用填充。
为了实现上述目的,本发明采用了如下技术方案:
一种轻质高压气体阻燃电缆用填充,包括基材、孔隙和玻纤带,所述基材的表面覆盖玻纤带,所述基材上具有多个孔隙,所述孔隙中充满CO2气体,CO2气体具有阻燃的效果。
进一步的,所述基材为30-40倍高发泡的EPE珍珠棉。
进一步的,所述孔隙中的CO2气体的压强为2-3个大气压强,高压CO2气体可使基材1不易变形。
进一步的,所述玻纤带的厚度为0.05mm。
所述基材的制备过程包括以下步骤:
步骤S1:按照重量比将基材的原料备好,并将其投入搅拌机中混合均匀,得到混合基料。本发明中的基材中EPE珍珠棉包括以下重量百分比的原料:低密度聚乙烯82%、四[β-(3,5-二叔丁基-4-羟基苯基)丙酸]季戊四醇酯0.8%、POE塑料(乙烯辛烯共聚物)8%、滑石粉5%、硬酸酯0.5-1%、MgO 1-2%、三聚氰胺1-1.5%、磷酸三苯酚1.5-2%。
步骤S2:将混合基料经由自动上料机均匀的送入挤出机;
步骤S3:挤出机通过螺标剪切及加热将混合基料进行融熔,挤出温区控制在90-180℃之间,挤出腔内部整体的温度分布保持中部温度高于两端温度的状态;
步骤S4:采用1.5MPa的高压N2将液化CO2和单甘脂送进机筒,其中液化CO2通过CO2泵进行输送,单甘脂泵通过单甘脂泵进行输送,CO2泵和单甘脂泵的进料部位设有单向阀,使原料不致反向倒流,以确保生产安全。
本步骤包括CO2发泡过程,发泡原理为高压液化CO2气化发泡,系物理发泡,与化学发泡比无污染。传统物理发泡中发泡剂常用丁烷,本发明中的CO2气化发泡相比于传统物理发泡中丁烷比更安全。另外,CO2可行性的重点在于相比于其他气体,其沸点相对高、易液化。
步骤S5:挤出后,混合基料在0.2-0.3MPaD的N2保压管中冷却成型,使其气孔中CO2保证有2-3个大气压,得到EPE珍珠棉管。本所述步骤S5中,成型后的EPE棉管的冷却包括以下步骤:
步骤A1:成型后的EPE棉管通过超声波加湿器迅速进行冷却,用于稳定棉管的相关参数,并且进行二次物理降温,使得棉管的物理性能更稳定;
步骤A2:从超声波加湿器出来的EPE棉管通过牵引辊,此时牵引速度应保持均衡,以保证棉管质量,牵引辊装有变频调速的电动机,可以随时调整牵引速度;
步骤A3:通过牵引辊出来的EPE棉管,进入风冷装置,进一步对棉管进行再次冷却成型。
本发明中的EPE棉管使用超声波加湿器迅速冷却步骤和风冷装置冷却步骤后,进入自动载切计数工序,采用变频控制,其速度可以在触模屏人机界面上设置裁切长度和计数,得到目标长度和数量的EPE棉管。
本发明的有益效果是:
1、本轻质高压气体阻燃电缆用填充密度仅为0.03g/cm3,比原较比PP填充绳(密度为0.9g/cm3)对比下降了300倍,填充质量轻,减少了电缆重量;同时阻燃性能明显提高,当火灾时,高温使EPE的聚乙烯熔化,2-3个大气压高压CO2释放,就如同在电缆中增加了CO2灭火器,具有灭火功效;其最外层的玻纤带在高温时形成膜进一步阻隔氧气,阻燃效果好。
2、本轻质高压气体阻燃电缆用填充因基材中的孔隙相互独立,且其材料为聚乙烯基材,完全满足电缆标准中的非吸湿性材料要求。
3、本发明中的高压液化CO2气化发泡,系物理发泡,与化学发泡比无污染,且相比于传统物理发泡中丁烷比更安全。
