聚醚酰亚胺‑环氧树脂电缆绝缘材料及其制备方法
摘要：
本发明公开了一种聚醚酰亚胺‑环氧树脂电缆绝缘材料及其制备方法，该制备方法包括：1)将沥青、桃胶、羊毛脂镁皂、木糖醇和米糠进行共混以制得改性沥青；2)将聚醚酰亚胺、环氧树脂、椰子纤维、马来酸酐、二氧化钛、硫代二丙酸双十八醇酯、膨润土、苯甲醇和改性沥青混炼、成型以制得聚醚酰亚胺‑环氧树脂电缆绝缘材料。通过该方法制得的聚醚酰亚胺‑环氧树脂电缆绝缘材料具有优异的绝缘性能和耐腐蚀性能，同时该制备方法具有工序简单、便于操作的优点。
摘要（英）：

The invention discloses a polyetherimide-epoxy resin cable insulation material and a preparation method thereof. The preparation method comprises the following steps: 1) blending asphalt, peach gum, lanolin magnesium soap, xylitol and rice bran to obtain modified asphalt; and 2) mixing polyetherimide, epoxy resin, coconut fiber, maleic anhydride, titanium dioxide, distearyl thiodipropionate, bentonite, benzyl alcohol and modified asphalt, and moulding to obtain the polyetherimide-epoxy resin cable insulation material. The polyetherimide-epoxy resin cable insulation material prepared by the preparation method provided by the invention has excellent insulating performance and corrosion resistance; and besides, the preparation method has the advantages of simple process and convenience in operation.
