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 lubricating oil for automobiles. The lubricating oil for automobiles comprises, by weight, 30 parts to 50 parts of modified nano-diamond, 50 parts to 70 parts of base oil, 20 parts to 30 parts of organic molybdenum compounds, 10 parts to 20 parts of preservative, 15 parts to 30 parts of cleaning agents, 10 parts to 20 parts of dispersing agents, 5 parts to 10 parts of abrasion-resistant agents, 5 parts to 10 parts of friction modifying agents and 2 parts to 3 parts of antioxidant. According to the lubricating oil for automobiles, the cleaning agents are used in the lubricating oil for automobiles so that surface deposition can be prevented, and the viscosity index of the oil can also be increased. According to the lubricating oil for automobiles, the preservative is added, metal parts are prevented from rusting, and the service life of automobiles is prolonged; abrasion is reduced by adding the abrasion-resistant agents, suspension of insoluble substances is kept by adding the dispersing agents, and oxygenolysis is performed by adding the antioxidant; the friction performance can be improved by the friction modifying agents.

Description

Technical field [0001] The invention relates to the technical field of vehicle lubricating oil, in particular to a vehicle lubricating oil and a preparation method thereof. Background technique [0002] At present, many solid lubricants have good performance, but due to their high density, they cannot be suspended in the oil, the particle size is coarse and the friction pair is not removed, and the agglomeration deposition is serious. After a long time, they block the oil circuit and cannot be used in lubricating oil. The extreme pressure anti-wear agents in traditional lubricating oils are often sulfur, phosphorus, and chlorides. Metal compounds are generated through boundary lubrication and instantaneous high temperature and high pressure and friction pairs to improve hardness and anti-wear properties. Although this compound is hard but very brittle, it is constantly shed and formed during the friction process, which corrodes the parts and consumes additives, and the service li...
