Abstract

The invention discloses pollution-free lubricating oil, which is prepared from the following raw materials in parts by weight: 600-1000 parts of base oil, 1-5 parts of docosanoic acid ester, 4-6 partsof hydrofluoric acid, 6-12 parts of cyclohexane, 20-30 parts of petroleum ether, 1-3 parts of benzyl alcohol, 4-10 parts of engine oil, 5-10 parts of an oxidation and corrosion inhibitor, 1-5 parts of nitric acid, 1-5 parts of sorbitol, 8-15 parts of methyl acrylate, 5-8 parts of a viscosity index improver, 2-4 parts of phosphite and 20-30 parts of water. The pollution-free lubricating oil provided by the invention is good in effect, uniform in lubricating oil concentration, small in friction coefficient and low in price; and by adding a certain amount of an additive, the property is stable,the use effect of the lubricating oil is not influenced, and the lubricating quality of the lubricating oil can be effectively improved.

Description

technical field [0001] The invention relates to a pollution-free lubricating oil, which belongs to the technical field of fine chemicals. Background technique [0002] Lubricating oil is divided into four categories according to its source: animal oil, vegetable oil, petroleum lubricating oil and synthetic lubricating oil. The amount of petroleum lubricating oil accounts for more than 90% of the total amount, so lubricating oil often refers to petroleum lubricating oil. It is mainly used to reduce the friction between the surfaces of moving parts, and at the same time, it has the functions of cooling, sealing, anti-corrosion, anti-rust, insulation, power transmission, and cleaning impurities for machinery and equipment. It mainly uses lubricating oil fraction and residual oil fraction from crude oil distillation unit as raw material. The most important properties of lubricating oil are viscosity, oxidation stability and lubricity, which are closely related to the compositi...
