Description

一种纳米蒙脱土改性聚乙烯电缆料及其制备方法
技术领域
本发明涉及高分子材料领域，特别是一种纳米蒙脱土改性聚乙烯电缆料及其制备方法。
背景技术
电缆用绝缘料一般要求必须具有优良的耐长期热老化性能、耐辐照、电气性能稳定、阻燃性能及绝缘性能优等特点。
聚乙烯（PE）是乙烯经聚合制得的一种热塑性树脂。在工业上，也包括乙烯与少量α-烯烃的共聚物。聚乙烯无臭，无毒，手感似蜡，具有优良的耐低温性能，化学稳定性好，能耐大多数酸碱的侵蚀。常温下不溶于一般溶剂，吸水性小，电绝缘性能优良。一般制做电线电缆用聚乙烯绝缘料，都是将聚乙烯原材料和各种助剂混合后由双螺杆挤塑机挤出造粒制备成。
发明内容
本发明的目的是提供一种纳米蒙脱土改性聚乙烯电缆料及其制备方法。
为了实现本发明的目的，本发明通过以下方案实施：

本发明所述纳米蒙脱土改性聚乙烯电缆料，由以下具体步骤制成：
（1）将低密度聚乙烯加热至熔融状态，加入纳米蒙脱土、抗氧剂1035、钛酸酯偶联剂TMC-TTS、2-甲基丙烯酸乙酯、炭黑N220、乙烯基三(β-甲氧基乙氧基)硅烷、助剂，搅拌捏合18-25分钟，送入双螺杆挤出机造粒，得到A料；
