Abstract:Although the complex lithium grease is the most widely used grease,there still some problems and weakness in lubrication and equipment wear.The influence of performance was studied through different solid additive,friction modifier and their respective complex formulation.Result shows that solid additive has a great influence on the extreme pressure antiwear properties of complex lithium grease;grease could has excellent EP and AW properties by compounding PTFE and MoS2,and it has synergistic effect by compounding Priolube 3986 complex ester and stearic acid,which can enhance reduce friction performance significantly.The compounding of solid additive and friction modifier has complementary advantage,overall raise the comprehensive properties of complex lithium grease.
