Abstract: The development status of US standard MIL-G-21164D(grease,molybdenum disulfide,for high and low temperature)and foreign-related grease products and technology,domestic standards and product were introduced. The comprehensive physical and chemical performance of lubricating grease B developed by SINOPEC Research Institute of Petroleum Processing Co., Ltd. can meet the requirements of MIL-G-21164D specification.With high structural strength and viscosity,grease B has more suitable thixotropic behavior unde high temperature conditions. Pressure differential scanning calorimetry(PDSC) shows that its oxidation induction period is longer,and the high temperature oxdation thermal stability is better.
