Abstract

A graphene / Fe2O3 nanometer particle composite lubricating oil additive is disclosed. The additive includes graphene the surface of which is loaded with Fe2O3 nanometer particles. The mass percentage of the graphene the surface of which is loaded with the Fe2O3 nanometer particles in lubricating oil is 0.002-1%. A method of preparing the additive is also disclosed. The additive is prepared by subjecting graphene oxide and a FeCl3 hydrate to a hydrolysis reaction, then centrifuging to obtain a solid product, washing the solid product with distilled water and ethanol for a plurality of times, and annealing. The additive has advantages of extremely good dispersibility and stability, good friction resistance and abrasion resistance and a high extreme pressure property, can be directly added into lubricating oil, and is capable of reducing the friction coefficient of a mechanical friction surface, restoring a worn surface, prolonging the service lifetime of machinery and reducing energy consumption. The method is simple, feasible, high in repetition rate and suitable for large-scale industrial production.

Description

technical field

[0001] The invention relates to the technical field of lubricating oil, in particular to a graphene / Fe 2 o 3 Nano particle composite lubricating oil, lubricating oil additive and preparation method thereof. Background technique

[0002] As an important part of the mechanical movement, lubricating oil plays the role of reducing friction, reducing wear, cooling, preventing corrosion, insulating, cleaning, and sealing; the performance of lubricating oil affects the service life of the machine, and Lubricating oil additives are the key substances to improve the performance of lubricating oils, and can make up for the shortage of base oils; from the perspective of market development trends, the growth trend of my country's lubricating oil additives market demand is consistent with the growth trend of domestic lubricating oil market demand, and the growth of the former The speed is obviously higher than the latter, mainly because the proportion of domestic high-gra...
