步骤四:在步骤三制备的玻璃纤维层上粘附一层胶液,在玻璃纤维层外侧挤包一层硅橡胶护套层;
步骤五:在步骤四制备的硅橡胶护套层外侧均匀涂覆一层胶液,在橡胶护套层外侧粘附一层腈纶防火布层,自然风干胶液使腈纶防火布层和硅橡胶护套层稳定粘合;
步骤六:在步骤五制备的腈纶防火布层外侧挤包一层外护套层,挤包过程中通过夹设有耐磨金属条的凹槽模具在外护套层上同步挤出夹设有耐磨金属条的耐磨凸棱;
步骤七:将步骤六制得的线缆进行产品性能测试,并将性能测试不合格的线缆产品剔除,保留合格的线缆产品;
步骤八:将步骤七中合格的线缆产品进行卷绕封装后打包入库。
作为优选,所述步骤六中的外护套层为低烟无卤聚烯烃护套层。
作为优选,所述步骤四挤包硅橡胶护套层后通过冰水浸没逐冷进行表层降温收束。
作为优选,所述步骤六挤包外护套层后在高压环境下通过低温氮气吹拂进行表层降温收束。
作为优选,所述步骤六中耐磨金属条的表面均匀环绕设置有防滑凸纹,所述耐磨金属条隐藏设置在耐磨凸棱内,耐磨金属条的顶部高度大于外护套层的外侧面高度。
