Abstract

The invention discloses a graphene lubricating oil additive and a preparation method thereof. The graphene lubricating oil additive is prepared from proper amounts of graphene, a hydrogenated styrene-diolefin copolymer, a borate and an oil-based solvent. The graphene lubricating oil additive disclosed by the invention solves the problem of corrosivity and selectivity in the traditional lubricating oil additive. The nano material additive technique is complex to operate, can discharge waste gas and pollutants, and can pollute the environment. The graphene lubricating oil additive can implement self-repair on the worn part, performs the functions of oil saving, wear resistance, noise reduction, power enhancement and the like, can be well dispersed in many types of lubricating oil base oil, has favorable oxidation stability, can exist stably for a long time, and is suitable for solving the problems of friction, wear and maintenance of different kinds of mechanical equipment under multiple working conditions.

Description

technical field [0001] The invention relates to a lubricating oil additive, in particular to a graphene lubricating oil additive and a preparation method thereof. Background technique [0002] In order to increase the anti-friction and anti-wear effect of lubricating oil, a small amount of lubricating oil additives are usually added to the lubricating oil. The traditional lubricating oil additives are sulfur, phosphorus or chlorine type anti-wear agents, which are corrosive to friction pair materials. Selectivity, especially lubricating oil additives containing elements such as sulfur, phosphorus or chlorine, will emit exhaust gas and pollutants during use, thus causing pollution to the environment. [0003] Nano-additives help to improve the performance of lubricating oil, and graphene, a new carbon material formed by the close arrangement of single-layer carbon atoms, has a single-layer two-dimensional honeycomb (Honeycomb) lattice structure, which is currently recognized ...
