Description

一种铁路信号电缆护套料
技术领域
    本发明主要涉及一种电缆料，尤其涉及一种铁路信号电缆护套料。
背景技术
    乙丙橡胶有优异的耐天候、耐臭氧、耐热、耐酸碱、耐水蒸汽、颜色性、电性能、充油性及常温流动性。乙丙橡胶制品在120℃下可长期使用，在150-200℃下可短暂或间歇使用。加入适宜防老剂可提高其使用温度。以过氧化物交联的三元乙丙橡胶可在更苛刻的条件下使用。三元乙丙橡胶在臭氧浓度50pphm、拉伸30%的条件下，可达150h以上不龟裂。由于乙丙橡胶缺乏极性，不饱和度低，因而对各种极性化学品如醇、酸、碱、氧化剂、制冷剂、洗涤剂、动植物油、酮和脂等均有较好的抗耐性；但在脂属和芳属溶剂（如汽油、苯等）及矿物油中性较差。因此通过加入新型助剂来改善传统乙丙橡胶的综合性能，来进一步提高电缆料的品质很有意义。
发明内容
本发明目的就是提供一种铁路信号电缆护套料。
本发明是通过以下技术方案实现的：

一种铁路信号电缆护套料制备方法，包括以下步骤：
将上N660炭黑与明矾粉混合，搅拌均匀，将1,2-双(三乙氧基硅基)乙烷加热到50-60℃后加入，充分搅拌，再加入十二烷基硫酸钠，400-500转/分搅拌分散3-5分钟，常温下加入硬脂酸，搅拌充分；将上述三元乙丙橡胶K5508放入开炼机内，75-80℃下混炼4-6分钟；将上述处理后的原料混合，加入除了硫化剂DCBP、六硫化双五甲撑秋兰姆以外的各原料混合，混炼4-6分钟，再加入剩余各原料，薄通6-7 次后，挤塑机塑化造粒，挤塑机的挤出温度为160-170℃，即得所述铁路信号电缆护套料。
本发明的优点是：
    本发明生产的电缆料具有很好的物理性能，抗拉伸、抗撕裂性能强，可以承受高压、磨损等不良环境，通过加入改性助剂增强了各物料间的相容性，进一步提高了成品的抗撕裂强度、回弹力性能等，本发明的电缆料具有环保、耐热、机械物料性能佳等优点。
