Abstract

The invention discloses a lubricant with good stability. The lubricant is prepared from the following raw materials in parts by weight: 700-1000 parts of neutral base oil, 1-5 parts of phosphoric acid, 4-6 parts of a viscosity index improver, 5-12 parts of a silane coupling agent, 20-35 parts of petroleum ether, 1-4 parts of benzyl alcohol, 4-10 parts of engine oil, 5-10 parts of zinc dialkyl thiophosphate, 1-5 parts of sulfurized isobutylene, 1-5 parts of a stabilizer, 10-15 parts of an extreme pressure anti-wear agent, 5-8 parts of nitric acid, 2-4 parts of glyceryl acrylate and 20-35 partsof water. The lubricant provided by the invention is good in stability, 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 lubricant with good stability and 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 composition o...
