Abstract

The invention discloses a lubricating oil which comprises the following components in percentage by weight: 10-25% of detergent dispersant, 5-15% of antioxidation and anticorrosion agent, 5-15% of extreme-pressure antiwear additive, 10-15% of tackifier, 1-3% of ferrite-base magnetic fluid and the balance of base oil. The lubricating oil additives can greatly improve the antiwear and anti-friction properties of the lubricating oil, enhance the heat stability and convert the iron powder and mud oil generated in the crankshaft and connecting rod tile working process into nano balls, thereby reducing the friction of the machine, lowering the oil temperature and prolonging the service life of the lubricating oil and machine.

Description

technical field [0001] The present invention relates to a lubricating oil. Background technique [0002] Friction and wear is a ubiquitous natural phenomenon, and lubricating oil is one of the most effective ways to reduce friction and resist wear. In-situ repair of worn surfaces during motion has always been the goal pursued by lubricators. Lubricating oil is generally composed of base oil and additives. Base oil is the main component of lubricating oil and determines the basic properties of lubricating oil. Additives can make up and improve some properties of base oil. Lubricating oil is divided into three categories according to its source: moving oil, vegetable oil, petroleum lubricating oil and synthetic lubricating oil. The amount of petroleum lubricating oil accounts for more than 97% 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. At the same time, it h...
