Abstract

The invention discloses lubricating oil. The lubricating oil is prepared from 70 to 80 portions by weight of base oil, 5 to 10 portions by weight of magnetic powder, 2 to 8 portions by weight of a viscosity improver, 1 to 5 portions by weight of a surface modifier, 2 to 5 portions by weight of a dispersant aid, 5 to 15 portions by weight of an anti-wear agent and 0.4 to 1 portion by weight of a wetting reinforcing agent. The preparation method comprises weighing the base oil, the viscosity improver, the surface modifier, the dispersant aid, the anti-wear agent and the wetting reinforcing agent in a mixer according to the weight part ratio, uniformly mixing the materials to obtain a mixture, heating the mixture to 200-250 DEG C, adding magnetic powder into the mixture, stirring the mixture until all the materials are completely dissolved, stopping stirring, cooling the mixture to the normal temperature, and standing the mixture for 3-5h to obtain lubricating oil. The novel lubricating oil greatly improves anti-wear and antifriction performances and improves thermal stability.

Description

technical field [0001] The invention relates to the technical field of fine chemicals, in particular to a 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. [0003] At present, most of the research and application at home and abroad are organic additives, while the research on inorganic additives is very little, and its application is even rarer. With the in-depth development of research in the field of l...
