Abstract

The invention relates to a graphene lubricating oil additive. The graphene lubricating oil additive comprises, by mass, 5-20 parts of a graphene oxide suspension, 1-5 parts of nanometer calcium carbonate, 2-4 parts of nanometer boron nitride, 3-6 parts of nanometer molybdenum disulfide, 2-8 parts of expanded graphite, 1-5 parts of nano-zirconia, 2-8 parts of nano-aluminua, 1-6 parts of nanometer titanium dioxide, 1-8 parts of nano-silica, 3-5 parts of N,N'-di-sec-butyl-p-phenylenediamine, 4-6 parts of di-tert-butyl-p-cresol, 2-5 parts of polyvinyl alcohol, 2-8 parts of methyl acrylate, 1-5 parts of pentaerythritol and 2-8 parts of nanometer zinc oxide. A ceramic-like layer formed by the lubricant additive has the advantage of ultrahigh hardness, super wear resistance, prolongation of the overhaul life of an engine, good lubricating performance, fuel saving, vibration reduction, engine noise reduction, power increase, reduction or eradication of the burning oil phenomenon and reductionof harmful gases in tail gas.

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. Contents of the invention [0003] The invention provides a graphene lubricating oil additive and a preparation method thereof to solve the problems of corrosion and selectivity in traditional lubricating oil additives, and is convenient for industrial popularization and applic...
