Abstract

The invention relates to gasoline engine lubricating oil with good anti-attrition performance and a preparation method thereof, and belongs to the technical field of lubricating oil. The gasoline engine lubricating oil with the good anti-attrition performance is prepared from, by weight, 80-90 parts of base oil, 0.05-0.2 part of organic molybdenum, 1-2 parts of sulfide modified oleic acid, 5-10 parts of diethylene glycol, 1-3 parts of dimethyl cyclohexyl amine, 1-3 parts of epoxy polyaniline, 1-3 parts of metal detergents, 1-3 parts of antioxidants, 1-5 parts of anti-wear agents, 3-7 parts of rust and corrosion inhibitors, 1-3 parts of friction modifiers, 1-3 parts of antifoaming agents and 1-2 parts of pour point depressants. According to the gasoline engine lubricating oil with the good anti-attrition performance and the preparation method thereof, the organic molybdenum and the sulfurized oleic acid are added to the lubricating oil, a synergistic effect is achieved through the organic molybdenum and sulfides, and the anti-attrition performance of the lubricating oil is improved.

Description

technical field [0001] The invention relates to a gasoline engine lubricating oil with good antifriction performance and a preparation method thereof, belonging to the technical field of lubricating oil. Background technique [0002] In the automotive industry, tribological behavior is a major cause of mechanical failure and energy consumption in vehicles. According to the energy distribution of typical vehicles measured by the U.S. Environmental Protection Agency (EPA), 62% of the fuel energy is consumed due to unavoidable heat dissipation, and the remaining 38% of the effective mechanical energy is consumed in various components of the vehicle. The friction loss of the components accounts for 10.5%. Facts have proved that: Reducing the energy loss caused by the friction of engine components is an important factor in achieving a reduction in vehicle fuel consumption. The improvement of engine design and the improvement of lubricating oil formulation technology will direct...
