Graphene-containing vegetable lubricant and preparation method thereof

Abstract

The invention discloses a graphene-containing vegetable lubricant. The graphene-containing vegetable lubricant is prepared from the following raw materials: castor oil, modified castor oil, liquid graphene, trimethyl citrate, N,N-dimethylacetamide, modified nano cerium vanadium oxide, modified sodium carboxymethylcellulose, sucrose ester, an organic molybdenum compound, dodecyl selenium, 4-hydroxy-4-methyl-2-pentanone, benzotriazole, polymethyl methacrylate, 1-butyl-3-vinyl imidazole hexafluoroantimonate, polyurethane, cyclohexane and an organic anti-aging agent. The graphene-containing vegetable lubricant disclosed by the invention has the advantages that the castor oil and other additives are combined, an environment-friendly vegetable lubricant is prepared, the balance of properties is achieved by controlling the types and quantity of the additives, the vegetable lubricant has better oxidation resistance and self-cleaning capability and also has good lubricating property, viscosity-temperature characteristic, low temperature fluidity, low volatility, corrosion resistance, anti-foam property and anti-emulsifying property, and the overall performance is good.

Description

technical field [0001] The invention relates to a lubricating oil, in particular to a graphene-containing vegetable lubricating oil and a preparation method thereof. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, cooling, rust prevention, cleaning, sealing and buffering. Lubricating oil is composed of base oil and additives. Base oil is the main component of lubricating oil and determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil and endow some new properties. An important component of oil. Engine lubricating oil, that is, engine oil, is the lubricating medium of the moving parts in the engine system. It has the functions of lubrication, cooling, cleaning and sealing to ensure the effective and long-term operation of the engine. ...

Problems solved by technology

[0003] The vast majority of traditional lubricating oils use mineral oil as the base oil, which has played a huge role in reducing friction and wear, saving energy, prolonging machine life and meeting the lubrication needs of harsh working conditions. However, when it is used in large quantities , will inevitably enter the environment through various channels such as transportation, leakage, splashing, spillage or inappropriate discharge, seriously polluting soil and water resources, destroying the ecological environment and ecological balance, even in the high regeneration rate of lubricating oil ( >60%) countries, 4-10% of lubricating oil still flows into soil and water
