Problems solved by technology

However, although the use of the above various additives has certain effects, due to the influence of temperature, pressure and friction, after a period of use, the currently used additives will consume or deteriorate by themselves, so the friction pair continues to wear, making the bearing bush or The mechanical size of the piston changes, and the fit is not precise, resulting in looseness

Abstract

An anti-wear repair additive for lubricating oil and a preparation method thereof. It relates to a lubricating oil additive and a preparation method thereof. Adding the lubricating oil additive into the lubricating oil can increase the hardness of the surface of the friction pair, improve its wear resistance, and repair the wear defects that have occurred, so as to prolong the working life of the friction pair. The invention consists of the following components according to the weight ratio: 1-10% of silicon powder, 0.5-5% of magnesium oxide, 20-70% of aluminum powder, 0.5-5% of titanium powder, 0.1-1% of nickel powder, and 0.1% of chromium oxide -1%, lithium nitride 1-5%, gold powder 0.1-1%, boron powder 5-20%; all the above components are crushed into particles with a diameter of 50μm-3nm and mixed evenly. When used in lubricating oil, under low temperature conditions, a high-hardness cermet layer can be formed, which not only has extremely high hardness, but also has an extremely low coefficient of friction and a temperature expansion coefficient similar to that of the friction pair. It can be used as lubricating oil anti-wear repair additive for cylinders, air compressors and other components.

Description

Technical field: [0001] The invention relates to a lubricating oil additive and a preparation method thereof. In particular, the invention relates to an anti-wear repair additive for lubricating oil and a preparation method thereof. Background technique: [0002] Lubricating oil works in the harsh environment of friction and extrusion for a long time. Due to the influence of factors such as high relative speed on the surface of the friction pair, large load, and temperature difference changes, the lubricating oil often deteriorates and loses its lubricating effect, resulting in wear on the working surface. Affect the normal work of the parts, or even accidents. [0003] In order to prolong the life of the surface of the friction pair, additives composed of various components are currently added to the lubricating oil. For example, in order to solve the problem of lubricating oil deposits, calcium petroleum sulfonate can be added to the lubricating oil; in order to increase...
