Description

technical field [0001] The invention relates to a vegetable composite engine oil, in particular to a vegetable composite engine oil containing graphene-inorganic non-metallic fibers. Background technique [0002] Engine oil is a liquid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. Engine oil generally consists of base oil and additives. Base oil is the main component of engine oil, which determines the basic properties of engine oil. Additives can make up for and improve the performance of base oil, endow some new performance, and are an important part of engine oil. Additives are the essence of engine oil. Proper selection and reasonable addition can improve its physical and chemical properties, endow the engine oil with new special properties, or strengthen its original perfor...

Problems solved by technology

[0004] Although the application of graphene in the field of composite engine oil has excellent performance, the problems existing in the application of graphene in the field of composite engine oil are also very obvious, which urgently need to be solved

The surface of graphene is highly inert, and the interaction with the composite engine oil 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.
