摘要
以端羟基聚丁二烯和液化二苯基甲烷二异氰酸酯为原料，加入扩链剂ＮＮ－１０１和填充剂硅微粉，在８０～１００℃，－０．０９５ＭＰａ条件下，制备了新型ＬＧ－３５聚氨酯灌封材料。该材料具有粘度低、常温可固化等优点，适用于３５ｋＶ级交联聚乙烯电力电缆连接盒的填充灌封。
A novel LG-35 polyurethane potting insulating material was prepared using hydroxyl-terminated polybutadiene and liquld isocyanate, with NN- 101 as chain extender and silica powder as filler at the temperature of 80～100℃ and pressure of - 0.095MPa. It had the advantages of low initial viscosity, curing at ambient temperature,less heat release and shrinkage during curing and fast curing. It could be used as a potting insulating material in cable splice.
