The invention provides a calcite type flaky calcium carbonate grease and a preparation method thereof, and the method is as follows: 20-40 parts of high-alkaline calcium sulfonate, 10-30 parts of an organic solvent and 2-10 parts of distilled water are stirred uniformly at 20-50 DEG C. Then 2-8 parts of a morphology control agent is added, CO2 gas is introduced, and the reaction is carried out for 1-3 hours. Then solid-liquid separation, washing and drying are carried out to obtain a calcium carbonate thickening agent; 20-60 parts of calcium carbonate thickening agent powder, 40-80 parts of base oil are uniformly mixed, and stirring thickening reaction is carried out at 160+ / -10 DEG C for 30-90 minutes, then the temperature is continuously kept at 200+ / -20 DEG C for 10-20 minutes, and after cooling, grinding is carried out, and the calcium carbonate grease is obtained. The method has low cost, simple raw materials and preparation process, stable production batch, and can effectively solve the problems of unstable grease batch, complex preparation process and the like. The calcium carbonate grease prepared by the method has outstanding high-temperature tribological properties, the drop point is higher than 385 DEG C, the shear stability and extreme pressure performance are excellent, and the lubrication requirements under harsh working conditions such as high temperature and high load can be met.
