Abstract

The invention discloses a nano-carbon molecular high-performance lubricating oil. The lubricating oil is prepared by taking mineral oil, engine oil, trimethylolpropane trioleate and glycerol ester of hydrogenated rosin as main ingredients and adding nano polytetrafluoroethylene, acrylic resin, propyl p-hydroxybenzoate, cetyl alcohol, nano-carbon, alkoxyl phosphate, acetyl tributyl citrate, hydroxybenzotriazole, overbased sulfurized calcium alkyl phenolate, methyl 4-bromo-5-azaindole-2-carboxylate, diisobutylene and surface modifier through heating stirring, ultrasonic dispersion, heating insulating, defoaming, mechanical shearing and other processes. Therefore, the lubricating oil has excellent dispersion stability and heat resistance, does not easily cause adhesion, can meet the requirement of industry, and has a relatively good application prospect.

Description

technical field [0001] The invention relates to the technical field of lubricating oil processing, in particular to a high-performance lubricating oil with nanometer carbon molecules. Background technique [0002] Lubricating oil 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. It mainly plays the roles of lubrication, auxiliary 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. [0003] In recent years, due to the unique physical, chemical and mechanical properties of nano solid lubricating materials, the industry has developed them into va...
