Abstract

The invention relates to an antioxidant system extreme pressure anti-wear self-repairing lubricating oil additive and a preparation method thereof. The lubricating oil additive comprises, by mass, 50-70% of an antioxidant, 10-25% of an anti-wear agent, 5-10% of an extreme pressure agent and 5-20% of organic molybdenum. The lubricating oil additive contains no routine mineral or synthetic base oil, and the content of the antioxidant is increased, so the antioxidant is also used as the base oil in the lubricating oil additive. The content of the antioxidant is increased, and then is used as a carrier, so anti-oxidation requirements under strict conditions (such as high speed, high temperature and high pressure) can be met, oil product failure caused by oxidation is prevented, and the life time of lubricating oil is prolonged; high efficiency synergism of the antioxidant and other components can be used to improve the extreme pressure anti-wear property of the oil product; and the lubricating oil additive also has a good self-repairing effect.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, and in particular relates to a lubricating oil additive, in particular to an anti-oxidation system extreme-pressure anti-wear self-repairing lubricating oil additive; the invention also relates to an anti-oxidation system extreme-pressure anti-wear self-repairing lubricating oil Methods of preparation of additives. Background technique [0002] Friction and wear is a common phenomenon in the friction process. According to statistics, more than one-third of the world's primary energy loss comes from friction. Therefore, reducing the economic loss caused by friction and wear is of great significance. Lubrication is an effective technology to reduce friction, reduce or avoid wear. At present, most lubricants improve their performance by adding a variety of lubricating additives, while traditional additives achieve good tribological properties through physical adsorption and chemical reaction...
