Abstract

The invention discloses a lubricating oil composition and a preparation method thereof. The lubricating oil composition is prepared from higher fatty acid amide, glycerol monostearate, ammonium molybdate, alkyl benzene sulfonate, a viscosity index improver, a pour point depressant, a defoaming agent, a metal cleaning agent, an antioxidant and the balance basic oil. The preparation method of the lubricating oil composition comprises the steps that the basic oil is heated to reach 75-85 DEG C, and the viscosity index improver and the pour point depressant are added to the basic oil and are evenly stirred; the mixture is cooled to reach 60-65 DEG C, the higher fatty acid amide, glycerol monostearate, the ammonium molybdate, the alkyl benzene sulfonate, the metal cleaning agent, the antioxidant and an anti-wear reagent at extreme pressure are added, and stirring is firstly performed for 30-50 minutes; the defoaming agent is added, and stirring is performed again for 10-20 minutes to obtain the product. Compared with existing advanced long-lasting lubricating oil, the cost is saved, the service life of the lubricating oil is prolonged, and the driving safety is improved.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a lubricating oil composition 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. Lu...
