AI Technical Summary

Problems solved by technology

Due to the high surface energy of the existing inorganic metal anti-wear agents, serious agglomeration is easy to occur in lubricating oil, which is not conducive to reducing friction, but will increase mass transfer resistance and aggravate friction loss

Abstract

The invention discloses lubricating oil with high wear resistance. The lubricating oil is prepared from the following raw materials in parts by weight: 50-65 parts of plant-based synthetic oil, 4-8 parts of polyethylene glycol fatty acid ester, 3-7 parts of polymethacrylate fatty alcohol ester, 8-13 parts of an anti-wear agent, 1-3 parts of graphene, 2-3 parts of a stabilizer, 1-3 parts of an antirust agent and 0.5-2 parts of an antioxidant. Equipment damage and energy loss caused by mechanical friction are remarkably reduced, and equipment abrasion and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to a lubricating oil with high anti-wear properties, which belongs to the technical field of new chemical materials. Background technique [0002] Lubricating oil is mainly used for lubrication, cooling, rust prevention, cleaning, sealing and buffering, etc. It is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. Lubricating oil generally consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil, endow some new properties, and are an important part of lubricating oil. Due to the high surface energy of the existing inorganic metal anti-wear agents, serious agglomeration easily occurs in lubricating oil, which is not conducive to reducing friction, but increases mas...
