Abstract

The invention discloses efficient composite lubricating oil, which is prepared from the following raw materials in parts by weight: 600 to 1000 parts of base oil, 1 to 6 parts of ferrite magnetic fluid, 4-6 parts of hydrofluoric acid, 8-12 parts of an extreme-pressure anti-wear agent, 20-30 parts of petroleum ether, 1-3 parts of a detergent dispersant, 4-15 parts of magnesium powder, 5-10 parts ofzinc alkyl thiophosphate, 1-6 parts of sulfurized isobutylene, 1-6 parts of sulfurized calcium alkyl phenolate, 10-15 parts of an oxidation and corrosion inhibitor, 5-8 parts of pentaerythritol, 2-4parts of an amine antioxidant and 20 parts of water. According to the invention, the efficient composite lubricating oil is good in effect, uniform in lubricating oil concentration, small in frictioncoefficient and low in price; and by adding a certain amount of 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 high-efficiency composite lubricating oil, belonging to the technical field of fine chemicals. Background technique [0002] Lubricants are divided into four categories: animal oil, vegetable oil, petroleum lubricating oil and synthetic lubricating oil according to their source. The consumption of petroleum lubricants accounts for more than 90% of the total consumption, so lubricants often refer to petroleum lubricants. It is mainly used to reduce the friction between the surfaces of moving parts, and at the same time has the functions of cooling, sealing, anticorrosion, rust prevention, insulation, power transmission, and cleaning impurities for machinery and equipment. The main raw materials are lubricating oil fraction and residual oil fraction from crude oil distillation unit. The main properties of lubricating oil are viscosity, oxidation stability and lubricity, which are closely related to the composition of lubricating o...
