Abstract
The invention discloses a graphene lubricant additive. The graphene lubricant additive comprises the following raw materials by weight: 20-30 parts of polyving akohol, 5-10 parts of alkyl glycoside, 5-10 parts of alkylphenol polyoxyethylene ether, 1-3 parts of dimethyl silicone, 1-3 parts of rare earth element of which the particle size is 20-50 nm, 4-6 parts of Cu of which the particle size is 20-50 nm, 4-6 parts of SiO of which the particle size is 20-50 nm, 0.1-1 part of graphene, 1-3 parts of 2,6-ditertiary butyl-4-methylphenol, 1-3 parts of benzotriazole, 3-5 parts of sodium alkyl benzene sulfonate, 3-5 parts of 2-mercaptobenzothiazole, and 3-5 parts of sodium benzoate. The graphene lubricant additive is added to the lubricant for passivating the catalytic action of the metal to the oxidation reaction, and inhibiting the oxidation process of the oils, so that the anti-oxygenation effect of the lubricant is enhanced, the service life of the lubricant is prolonged, and the machine can be protected.
Description
technical field [0001] The invention relates to a lubricating oil, in particular to a graphene lubricating oil additive and a preparation method thereof. Background technique [0002] Friction and wear is one of the most common problems encountered in many fields. Friction and wear consume a lot of energy, and a lot of material and equipment are wasted as a result. With the rapid development of science and technology and the improvement of machinery manufacturing technology, a large number of high-speed and heavy-duty working conditions have appeared, which put forward higher requirements for the high-temperature bearing capacity and anti-friction and anti-wear performance of lubricating oil. Lubricant additives are critical to improving lubricant performance. [0003] Lubricating oil is a liquid lubricant used on various types of machinery to reduce friction and protect machinery and processed parts. It mainly plays the role of reducing friction, cooling, sealing, bufferi...
