Abstract

An antiwear self-repairing lubricating oil additive is composed of the following components in parts by mass: 10-22 parts of molybdenum diisooctyl dithiophosphate, 18-28 parts of triphenyl phosphate,15-20 parts of an antiwear agent and 10-30 parts of an antioxidant. With use of special antiwear agent components, the antiwear agent composed of sulfurized isobutylene, dibenzyl disulfide, di-n-butylphosphite, sodium metaborate, and a potassium metaborate material is added into lubricating oil, the lubricating oil is subjected to a chemical reaction with a metal surface, and a chemical reactionfilm is produced, so a lubricating effect is played, scratching of the metal surface is prevented, even fusion welding is prevented, the self lubricating performance of the lubricating oil is greatlyimproved, and the antiwear self-repairing effect is good. With special preparation of the multi-component antioxidant, the antiwear self-repairing lubricating oil additive has excellent anti-aging andanti-oxidation performance, is added into the lubricating oil, can highly delay the service life of the lubricating oil and improves the practical performance.

Description

Technical field [0001] The invention particularly relates to an anti-wear and self-repairing lubricant additive 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, it is of great significance to reduce the economic loss caused by friction and wear. Lubrication is an effective technology to reduce friction, reduce or avoid wear. [0003] At present, most lubricants use a variety of lubricating additives to improve their performance, while traditional additives achieve good tribological performance through physical adsorption and chemical reactions. They cannot achieve zero wear and damage to materials. To repair. Lubricating additives determine the performance of lubricants to a large extent. The development and development of new self-repairing lubricating additives to blend lubricating oils, ...
