High-temperature-resistant universal extreme-pressure grease lubricant and preparation method thereof

The invention discloses a high-temperature-resistant universal extreme-pressure grease lubricant and a preparation method thereof. The grease lubricant is prepared by taking petroleum calcium sulfonate, base oil, glacial acetic acid, dodecahydroxyl stearic acid, boric acid, calcium hydroxide and arylamine antioxidant as raw materials and utilizing a simpler production process; the production process has fewer procedures and lower production cost, and the production efficiency is improved; meanwhile, the grease lubricant has a stronger commonality while being applied and the grease lubricant can be applied to the fields with higher requirements on temperature, precision and bearing capability; the grease lubricant is stable in lubrication performance and longer in use period. The commonality of the grease lubricant provided by the invention is improved and the type of product is specially researched.
