摘要（英）：

The invention discloses high-performance complex lithium-calcium base grease composition and a method for preparing the same. The high-performance complex lithium-calcium base grease comprises the following raw materials by proportion: (A) base oil which is 50-95 percent of the total weight of the high-performance complex lithium-calcium base grease, (B) C12-C22 monoprotic organic acid in which the thickening agent is 3-15 percent of the total weight of the high-performance complex lithium-calcium base grease, and (C) additive. The method for preparing the high-performance complex lithium-calcium base grease comprises the following steps: adding and stirring the base oil, the monoprotic organic acid and binary low-molecular acid, heating the mixture to 80-100 DEG C, adding calcium hydroxide suspension, adding calcium hydroxide emulsion, preserving the heat of the mixture for 10-40 min, heating the mixture, adding the residual base oil, cooling the mixture, adding the additive composition, decreasing the temperature of the mixture to blow 100 DEG C, homogenizing and degassing the mixture to obtain the finished product. The high-performance complex lithium-calcium base grease has good shearing performance, high dropping point and excellent extreme pressure anti-wear performance, is easy to prepare and can save the energy.
