Problems solved by technology

Although this compound is hard but very brittle, it will continue to fall off and form continuously during the friction process, which not only corrodes the machine parts, but also consumes additives. The service life of both machinery and lubricating oil is very short.
The anti-wear components in traditional lubricating oils, such as zinc dialkyldithiophosphate (T202 anti-oxidant and anti-corrosion agent), contain sulfur, phosphorus, and zinc, which not only corrode silver bearings, poison the catalyst of the exhaust gas conversion device, but also pollute the atmospheric environment

Abstract

The invention discloses abrasion-resistant automobile lubricant oil which is prepared from the following components in parts by weight: 25 to 40 parts of modified nano diamond, 40 to 80 parts of base oil, 20 to 30 parts of organic molybdenum mixture, 10 to 20 parts of abrasion-resisting agent and 20 to 30 parts of preservative. The invention further discloses a preparation method of the abrasion-resistant automobile lubricant oil. The abrasion-resisting agent is applied to the automobile lubricant oil, so that the friction and the abrasion can be reduced, and the viscosity index of the automobile lubricant oil can also be improved. Meanwhile, the preservative is added into the automobile lubricant oil, so that a metal component is prevented from being rusted. Thus, the service life of an automobile is prolonged.

Description

technical field [0001] The invention relates to the technical field of lubricating oil for vehicles, in particular to a wear-resistant lubricating oil for vehicles and a preparation method thereof. Background technique [0002] At present, there are many solid lubricants with good performance, but due to their high density, they cannot be suspended in the oil, and the particle size is too coarse to get into the friction pair. The agglomeration is serious, and the oil passage is blocked after a long time, so they cannot be used in lubricating oil. The extreme pressure and antiwear agents in traditional lubricating oils are often some sulfur, phosphorus, and chloride compounds. Through boundary lubrication, instantaneous high temperature and high pressure and frictional pairs form metal compounds to improve hardness and wear resistance. Although this compound is hard but very brittle, it will continue to fall off and form continuously during the friction process, which not onl...
