Description

一种具有抗霉菌功能的电缆护套料
技术领域
    本发明主要涉及一种电缆料，尤其涉及一种具有抗霉菌功能的电缆护套料。
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具有抗霉菌功能的电缆护套料。
本发明是通过以下技术方案实现的：

一种具有抗霉菌功能的电缆护套料制备方法，包括以下步骤：
将上述硅灰石粉与碳酸锂混合，加入2-(3，4- 环氧环己基) 乙基三甲氧基硅烷，在50-60℃下搅拌加热10-14分钟，加入聚乙烯蜡，充分搅拌后冷却至常温；将上述三元乙丙橡胶K520放入开炼机内，70-80℃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、促进剂TMTD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℃，即得所述具有抗霉菌功能的电缆护套料。
本发明的优点是：
本发明生产的电缆料可以有效的抑制霉菌的生长、成型和繁殖，使电缆免受霉菌的侵害；能够避免因霉菌生长而被迫更换电缆，造成电缆的使用寿命减少和供电局的损失，延长了电线电缆的使用寿命，本发明的电缆料具有很好的物理性能，耐热、抗拉伸、抗撕裂性能强，综合性能好。
