Abstract

The invention discloses a high-efficiency wear-resistant energy-saving lubricating oil composition and a preparation method thereof. The high-efficiency wear-resistant energy-saving lubricating oil composition is prepared from the following raw materials in parts by weight: 40-60 parts of polyester base oil, 10-20 parts of pentaerythritol ester base oil, 5-10 parts of modified nano graphite, 0.5-1.5 parts of emulsifying agent, 1.5-3.5 parts of friction modifier, 2.5-4.5 parts of petroleum calcium sulfonate, 1-3 parts of octadecylamine, 0.4-0.6 part of composite antioxidant, 0.7-0.9 part of extreme-pressure antiwear agent, 0.6-0.8 part of preservative and 0.6-0.9 part of anti-foaming agent. The high-efficiency wear-resistant energy-saving lubricating oil composition has better wear-resistant and wear-reducing properties, and can repair and reduce wear; meanwhile, due to addition of the preservative, rusting of metal parts can be prevented and the service life of a car is prolonged.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a high-efficiency anti-wear and energy-saving lubricating oil composition and a preparation method thereof. Background technique [0002] As the manufacture of the engine becomes more and more sophisticated, the requirements for lubricating oil become more and more stringent. It is difficult for the existing engine oil to guarantee the normal operation of the engine, which leads to aggravated wear of the engine, serious corrosion of the piston ring and cylinder liner, and serious corrosion of the filter oil. The grid is clogged and the oil change interval is shortened. [0003] Therefore, the lubricating oil used is required to have good wear resistance and reduce wear and tear of the engine. [0004] In response to the above problems, the prior art was searched, and a lubricating oil was disclosed in the Chinese invention patent application 200810241687.2 (publication d...
