技术领域
本发明涉及复合材料领域,具体涉及一种抗开裂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。
