Abstract

The invention provides a lubricating grease composition for an automobile glass lifter and a preparation method of the lubricating grease composition. The lubricating grease for the automobile glass lifter comprises the following ingredients in percentage by weight: 87 to 91.5 percent of basic oil, 7.5 to 12 percent of thickening agents, 0.5 percent of antioxidants, 0.03 percent of anti-rust agents and 0.5 percent of structure improving agents. The unique mixed thickening agent type is adopted, so the water-resistance and shearing performance of the lubricating grease are excellent, good low-temperature and viscosity-temperature performance is given to the lubricating agent through the proper basic oil type and mixture ratio, and the wide temperature use requirement being minus 40 DEG C to 70 DEG C of the automobile glass lifter accessories can be perfectly met. The prepared lubricating grease has the characteristics that the water resistance and the oxidation resistance are excellent, the oil rate is low, the evaporation loss is small, the shearing stability is high, the high-low temperature performance and the anti-corrosion protection effect are good, and the like, the use requirements of the automobile glass lifter can be perfectly met, and the use temperature range of the lubricating grease is minus 40 DEG C to 130 DEG C.
