Abstract

The invention discloses a lubricant additive and a preparation method thereof. The lubricant additive comprises high-grade fatty acid amide, glycerol monostearate, ammonium molybdate, alkylbenzene sulfonate, viscosity index improver, pour point reducer, anti-foaming agent, metal detergent, antioxidant and the balance being oil solvent. The preparation method includes heating oil solvent to the temperature of 75-85 DEG C, and adding viscosity index improver and pour point reducer into oil solvent with uniform stirring; lowering the temperature of the mixture to 60-65 DEG C, adding high-grade fatty acid amide, glycerol monostearate, ammonium molybdate, alkylbenzene sulfonate, metal detergent, antioxidant and extreme pressure antiwear additive, and stirring for 30-50 min for the first time; adding anti-foaming agent and stirring for 10-20min for the second time to obtain the product. Compared with existing high-class long-acting lubricant, the lubricant additive has the advantages that cost is saved, service life of lubricant is prolonged, and safety in travelling is improved.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a lubricating oil additive and a preparation method thereof. Background technique [0002] With the rapid development of the automobile industry, the number of automobiles in my country has increased significantly. Automobile energy consumption and environmental protection issues have aroused great concern from the whole society. The fuel combustion efficiency and lubrication and wear conditions of the automobile engine under the service conditions have the most significant impact on the energy consumption and environmental protection of the automobile, and put forward higher requirements for the lubricating performance and long-term stability of the lubricating oil. Friction and wear is a ubiquitous natural phenomenon. Friction loses about one-third of the world's primary energy. Wear is one of the three most important forms of damage and failure of materials and equipment. Lubri...
