Problems solved by technology

[0003] Although graphene has excellent performance in the application of lubricating oil, the problems existing in the application of graphene in the field of lubricating oil are also very obvious, which urgently need to be solved
The surface of graphene is highly inert, and the interaction with lubricating base oil molecules is weak, resulting in poor dispersion stability. In addition, there is a strong van der Waals force between graphene sheets, which makes graphene easy to agglomerate on the one hand. On the other hand, under the action of friction interface extrusion, it is easy to form a dense film, which cannot maintain the porous structure of the interface protective film.

Description

technical field [0001] The invention relates to a vegetable lubricating oil, in particular to a vegetable lubricating oil containing graphene-polymer fibers. Background technique [0002] With the development of machinery, lubricating oils that reduce friction, reduce wear, cool down, prevent corrosion, insulate, clean, and seal are becoming more and more important. 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. Lubricating oil additives are a key part of lubricating oil, which can make up for the lack of base oil and greatly improve the lubricating oil. The performance of the oil, the additive can make up ...
