Abstract

The invention discloses lubricating oil for an engine and a preparation process thereof. The lubricating oil is prepared from the following raw materials in parts by weight: 49 to 69 parts of polyalkylene glycol base oil, 15 to 35 parts of PAO base oil, 0.5 to 1.5 parts of a tackifier, 1.5 to 3.5 parts of a friction modifier, 2.5 to 4.5 parts of organic molybdenum, 1 to 3 parts of borate additive,0.4 to 0.6 part of a complex antioxidant, 0.7 to 0.9 part of an anti-wear reagent at extreme pressure, 0.6 to 0.8 part of a preservative and 0.6 to 0.9 part of an anti-foaming agent. The lubricatingoil for the engine provided by the invention has better wear resistance, and can repair abrasion and reduce abrasion.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to an engine lubricating oil and a preparation method thereof. Background technique [0002] The engine is the heart of automobiles and many industrial equipment, and its lubricating oil consumption accounts for about 50% of the total lubricating oil. As the blood of the engine, engine oil plays the roles of lubrication, cooling, sealing, cleaning, anti-rust and anti-corrosion, etc. It is a functional liquid to keep the engine running long and efficiently. [0003] 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 i...
