摘　　要：为探究二甲苯基二丁基苯丙呋喃酮(HP-136)与4,4′-硫代双(6-叔丁基-3-甲基苯酚)(300#)复配对高压交联聚乙烯(XLPE)电缆绝缘料性能的影响,通过熔融共混的方式制备出含有苯丙呋喃酮复合抗氧剂的高压绝缘料,并对其挤出性能、流变性能、氧化诱导期、抗焦烧性能等综合性能进行测试分析。结果表明:HP-136的加入,提高了绝缘料的介电性能,降低了副产物含量,并改善了高压绝缘料交联后的颜色;当HP-136与300#添加质量比为1∶3时,高压绝缘料的氧化诱导时间最长。In order to study the effect of the compound of dimethyl phenyldibutyl phenylfuranone(HP-136)and 4,4′-thiobis(6-tert-butyl-3-methylphenol)(300#)on the insulation performance of high voltage cross linked polyethylene(XLPE)cable,a high-voltage insulating material containing phenylfuranone compound antioxidant was prepared by melt blending,the extrusion properties,rheological properties,oxidation induction period and scorch resistance were tested and analyzed.The results show that the addition of HP-136 improves the dielectric properties,decreases the by-product content and improves the color of the cross-linked high voltage insulator.When the mass ratio of HP-136 to 300#is 1∶3,the oxidation induction time of high voltage insulator is the longest.
