摘　　要：采用熔融插层复合法制备了一种新型的电(光)缆护套料———聚乙烯/蒙脱土纳米复合材料。傅里叶变换红外光谱(FTIR)测试表明,有机阳离子已和蒙脱土中的钠离子发生了交换作用,x射线衍射(XRD)测试表明聚乙烯已经进入到蒙脱土片层间,形成了插层型纳米复合材料。测试了复合材料的热学性能和力学性能,试验表明聚乙烯/蒙脱土纳米复合材料比传统的聚乙烯护套料在耐热性能和力学性能等方面均有显著提高。A new cable sheath compound made of polyethylene （PE） and montmorillonite （MMT） nanocomposite by melt intercalation is developed. FTIR test shows that the organo-cations have had exchange reaction with Na^＊ in the MMT. And XRD test shows that PE has entered into layers of montmorillonite to form intercalated nanocomposite. The thermal and mechanical properties of PE/MMT nanocomposite are tested. The results show that it exhibits significant improvement in both heat resistance and mechanical performance over traditional PE sheath compound.
