摘　　要：考察了原料比例和制备工艺对苯二甲酸复合锂基润滑脂性能的影响,结果表明,当12-羟基硬脂酸与对苯二甲酸及癸二酸的比例为1∶0.2∶0.3时,所制备的复合锂基润滑脂比癸二酸复合锂基润滑脂具有更小的压力分油、钢网分油及更好的耐高温性。The effects of the proportion of raw materials and preparation process on the performance of lithium complex grease with terephthalic acid were investigated.The results show that when the ratio of 12-hydroxy stearic acid to terephthalic acid and sebacic acid is 1∶ 0.2∶ 0.3,the obtained lithium complex grease has smaller pressure oil,steel net oil and better high temperature resistance than the lithium complex grease with sebacic acid.
