Abstract

The invention discloses a graphene oxide lubricating additive and its application in anti-wear automatic transmission oil. The graphene oxide lubricating additive is condensed at high temperature by graphene oxide, titanium borate, 1-(2-hydroxyethyl)-3-decylimidazole bistrifluoromethanesulfonylimide lithium salt ionic liquid, ethanol, and concentrated sulfuric acid Reflux, remove ethanol by evaporation under reduced pressure. Compared with the prior art, applying the graphene oxide lubricating additive of the present invention to the anti-wear automatic transmission oil can improve the quality of the transmission oil very well, so that the anti-wear automatic transmission oil has good rust resistance Resistance, oxidation resistance; at the same time, it also has excellent extreme pressure and anti-wear properties and good friction characteristics.

Description

technical field [0001] The invention specifically relates to a graphene oxide lubricating additive and its application in anti-wear automatic transmission oil. Background technique [0002] Lubricating 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, cooling, rust prevention, cleaning, sealing and buffering. 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. The American Petroleum Institute (API) divides base oils into five categories: I, II, III, IV, and V. Types I, II, and III belong to mineral base oils. Type IV refers to polyalphaolefins (PAO). I, II, and III Tho...
