Abstract

The invention discloses a mechanical anti-wear repairing lubricant and a preparation method thereof. Aiming at the defects existing in the existing mechanical anti-wear repairing lubricants, it consists of base oil, glycerin, inorganic non-metallic salts, high-temperature antioxidants, and water-soluble surfactants. agent, polyvalent polycarboxylic acid, friction modifier, extreme pressure antiwear agent, and metal deactivator are made according to a certain preparation method. The mechanical antiwear repair lubricant of the present invention not only has extreme pressure performance, but also has very Strong high-temperature and high-load anti-wear performance breaks through the defect that lubricating materials are difficult to meet the needs of new engine development, and plays a very good role in repairing the friction of modern high-efficiency development engines during high-speed, high-pressure, and high-temperature operation. It increases the service life of the engine and has strong practical value.

Description

technical field [0001] The invention relates to a lubricant and its preparation, in particular to a mechanical anti-wear repair lubricant and its preparation method. Background technique [0002] During the high-speed, high-pressure and high-temperature operation of the engine, various friction interactions are likely to produce severe friction. Long-term friction will cause wear on the friction pair interface, thereby reducing work efficiency and increasing maintenance costs. At present, lubricating oils for internal combustion engines on the market are all ordinary engine oils, and their shear properties are particularly easy to decrease under high temperature, high pressure, and high friction conditions, resulting in a decrease in lubricating performance. In order to maintain normal lubrication performance, the oil must be replaced after the vehicle has traveled about 5,000 kilometers. Frequent replacement of engine oil will not only increase the cost of engine use but a...
