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 anti-oxidation automobile lubricating oil. The anti-oxidation automobile lubricating oil is composed of, by weight, 30-50 parts of modified nano-diamonds, 50-70 parts of base oil, 20-30 parts of an organic molybdenum mixture, 10-20 parts of an antioxidant and 15-30 parts of a friction improver. The invention further discloses a preparation method for the anti-oxidation automobile lubricating oil. The antioxidant is applied to the automobile lubricating oil so that oxygenolysis of effective constituents in the lubricating oil can be restrained and oil viscosity indexes can also be improved. Meanwhile, the friction improver is also added, so that friction performance is improved, and 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 an anti-oxidation 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 on...
