一种高耐水硅烷交联聚乙烯绝缘复合材料及其制备方法
技术领域
本发明涉及复合材料领域，具体涉及一种高耐水硅烷交联聚乙烯绝缘复合材料及其制备方法。
背景技术
聚乙烯产量大、来源丰富、价格低廉，是一种用途广泛的树脂。然而聚乙烯的相容性低，耐候性和机械性能存在不足，综合性能较差，需要改善性能。其中，对聚乙烯进行交联改性是改善聚乙烯性能的重要手段之一，能提高聚乙烯制品的机械性能、耐化学性能和耐开裂性能等，扩宽了聚乙烯的应用范围。
聚乙烯交联技术包括辐射交联、过氧化物交联、硅烷交联等，其中硅烷交联聚乙烯具有工艺设备简单、操作灵活方便、经济性好的特点，受到广泛的关注和重视。硅烷交联聚乙烯具有良好的绝缘性能，主要应用于中、低压电线、电缆的生产，具有良好的市场前景和极高的经济效益。随着市场需求的进一步发展，硅烷交联聚乙烯材料也需要进一步完善力学性能、耐候性等方面的缺陷，提高技术指标，从而满足各个领域的特殊要求。
发明内容
本发明的目的是提供一种高耐水硅烷交联聚乙烯绝缘复合材料，力学性能、耐候性良好，应用范围广。
本发明是通过以下技术方案实现的：

一种高耐水硅烷交联聚乙烯绝缘复合材料的制备方法，包括以下步骤：
(1)将滑石粉、叶蜡石粉和轻质碳酸钙与三聚磷酸钠混合后先共同研磨1-2h，洗涤过滤并将滤饼于200-300℃条件下处理1-2h，冷却后研磨均匀，过600-800目筛，得混合填料；
(2)将聚丙二醇加入反应釜中真空干燥0.5-1h，然后将温度调至70-80℃，并加入二苯基甲烷二异氰酸酯于真空条件下200-400r/min搅拌反应2-4h，得聚氨酯预聚体；
(3)将(1)中的混合填料与(2)中的聚氨酯预聚体混合后加入线性酚醛树脂，先于800-1000r/min搅拌1-2h，再加入单甘油硬脂酸酯、柏油和白矿油共同球磨2-4h，得改性填料；
