Abstract

The invention relates to an anti-wear self-repairing material, especially to a graphene-based high-molecular nanometer alloy anti-wear self-repairing material and a preparation method and application thereof, belonging to the field of high-molecular materials. A graphene-based high-molecular nanometer alloy anti-wear self-repairing agent prepared in the invention realizes the breakthrough that heavy-load anti-wear anti-attrition effect almost reaches the level of zero wearing and overcomes the two world-famous problems of proneness to agglomeration and precipitation and incapability of better performing extreme-pressure anti-wear effect of a metal nanometer anti-wear material in fluid lubrication products; the agent provides core technological guarantee for development fluid lubrication technology and mechanical equipment towards impact resistance, heavy load, high carrying capacity, miniaturization, low viscosity, low energy consumption and high reliability; and the agent provides superhigh engine performance and protection effect, guarantees economic performance of vehicle combustion and has superstrong anti-wear and lubrication performance, metal deactivation performance and the performance of self-repairing of metal wearing.

Description

technical field [0001] The invention relates to an anti-wear self-repairing material, in particular to a graphene-based polymer nano-alloy anti-wear self-repairing material and its preparation method and application, belonging to the field of polymer materials. Background technique [0002] With the increasing power, speed, precision and other parameters of modern mechanical equipment, the workload is getting higher and higher, and the use environment is becoming more and more harsh, resulting in the wear and life of mechanical parts being greatly affected. In order to improve the lubricating oil For lubricating performance, anti-wear performance and prolonging equipment life, we need to add a certain amount of extreme pressure anti-wear agent to it to reduce the friction resistance between friction surfaces and prevent material wear and abrasion. Therefore, it is of great significance to study environmentally friendly lubricating oil additives with outstanding extreme press...
