Problems solved by technology

However, under harsh working conditions such as high speed, high temperature, and high pressure, a large amount of peroxides, alcohols, and hydroxy acids are produced in the oil, which makes the viscosity of the oil increase faster. When the amount of antioxidant in the additive is small However, it cannot meet the anti-oxidation requirements under severe working conditions, so it is necessary to use a large amount of composite antioxidants to improve the anti-oxidation performance of oil products at different temperatures, especially to enhance the anti-oxidation effect at high temperatures

Abstract

The invention provides a lubricating oil additive for electromechanical devices, and a preparation method thereof. The lubricating oil comprises, by weight, 20-30 parts of an antioxidant, 20-33 parts of an anti-wear agent, 12-25 parts of an extreme pressure agent and 8-18 parts of organic molybdenum. The preparation method comprises the following steps: mixing the antioxidant, the anti-wear agent, the extreme pressure agent and the organic molybdenum, heating and stirring the obtained mixture at 80-100 DEG C for 30-50 min to obtain the lubricating oil additive. The content of the antioxidant is increased, and then is used as a carrier, so anti-oxidation requirements under a high speed at a high temperature under a high pressure are 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 lubricating oil, and in particular relates to a lubricating oil additive for electromechanical equipment and a preparation method thereof. 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 reactions, which cannot achieve zero wear and damage to materials. to repair. Lubricating additives determine the performance of lubricants to a large extent. It is of great significance to the nationa...
