技术领域
本发明涉及一种电缆料，具体涉及一种耐温变改性TPE树脂电缆料及其制备方法。
背景技术
电缆料是电线电缆绝缘及护套用塑料的统称，以橡胶、塑料、尼龙等材质作为基料，结合增塑剂、填料、色母料、抗氧剂等辅助成分制成，不同电缆种类和使用环境对电缆料的性能有不同的要求，市售电缆料大都存在不耐划伤折叠、易腐蚀氧化内部金属导线、阻燃性能较差、硬度与韧性不能兼顾、燃烧时毒性较大、不耐潮湿寒热等缺点，制约着电缆的安全性和使用寿命，因此，急需研发新型的性能均衡、环保安全、实用性强的电缆料。
发明内容
本发明的目的在于，提供一种耐温变改性TPE树脂电缆料及其制备方法，改进了TPE树脂为主要基材的电缆料的使用性能，为了实现上述目的，本发明采用的技术方案如下：
一种耐温变改性TPE树脂电缆料及其制备方法，其特征在于，该电缆料由以下重量份的原料制成：聚己内酰胺8-12、衣康酸二甲酯4-6、硅酸镁20-30、氧化锰3-6、TPE树脂50-70、间规聚苯乙烯20-35、亚磷酸酯6-8、鲸蜡醇4-6、酯化碳酸钙10-14、色母料5-8、助剂2-3。
所述的助剂由以下重量份的原料制成：无水乙醇6-8、氮化铝粉12-15、锡酸锌2-3、乙烯基硅烷偶联剂1-2、三乙醇胺硼酸酯2-3，制备方法为：先将锡酸锌、乙烯基硅烷偶联剂、三乙醇胺硼酸酯与无水乙醇混合分散均匀，随后将氮化铝粉投入混合溶液中，研磨分散20-30min后，将粉体室温干燥，除去无水乙醇，得助剂。
所述的一种耐温变改性TPE树脂电缆料及其制备方法，其制备方法如下：
(1)将衣康酸二甲酯加热至35-40℃，待其熔融后，加入氧化锰，搅拌分散均匀，冷却至分散后备用；
(2)将聚己内酰胺、TPE树脂、间规聚苯乙烯混合均匀后，加热至40-50℃，接着加入亚磷酸酯、鲸蜡醇，继续搅拌分散30-50min，随后物料冷却至室温，再加入其它剩余物料及步骤(1)所得物料，一起投入高速混料机中混合均匀后，送入双螺杆造粒机中挤出造粒，即得所述电缆料。
所述的双螺杆挤出机各段的温度为：加料段：90-100℃、压缩段：180-220℃、均化段180-190℃、机头温度：120-130℃。
有益效果：以TPE树脂作为基料，佐以聚己内酰胺、间规聚苯乙烯等高分子材料，改进了TPE树脂的力学性能，再结合预先经衣康酸二甲酯处理的氧化锰及硅酸镁、鲸蜡醇等成分和具有促混合、抑烟等功效的助剂，使得本发明电缆料改进了传统TPE树脂不耐温变的特性，耐热性能得到提高，且隔氧防火、抗压耐磨，性能稳定安全，实用性强。
