一种耐低温汽车同轴电缆护套用PVC电缆料及其制备方法、以及耐低温汽车同轴电缆

本发明提供一种耐低温汽车同轴电缆护套用PVC电缆料，包括以下重量份组分：PVC树脂60～110份、偏苯三酸三辛酯5～30份、F‑510复配酯类增塑剂5～30份、对苯二甲酸二辛酯0～30份、碳酸钙20～40份、钙锌稳定剂5～20份、润滑剂1～5份、增韧剂1～5份。本发明还公开了一种耐低温汽车同轴电缆护套用PVC电缆料的制备方法以及一种耐低温汽车同轴电缆。与现有技术相比，本发明将低温脆化温度由‑20℃降低至‑25℃以下，制成的同轴电缆可通过ISO 19642低温卷绕、低温冲击测试；对比密炼机生产，能耗降低约一半；挤出生产速度提升30%，下游护套挤出速度提升40%，线缆表面优化；且无需添加阻燃剂即可满足阻燃要求，更加环保。
