Abstract

The invention relates to a surface modified nano metal oxide anti-wear self-repairing material and a preparation method thereof. The prepared product is good in oil solubility, the generation of sediment of the product in lubricating oil, which affects the extreme pressure and anti-wear performance of the product, is avoided, and the product can be dissolved in lubricating oil of all models. The product has excellent load resistance and extreme pressure and anti-wear performance and is suitable for heavy-duty mechanical lubrication and extreme pressure anti-wear; and the product has a smart self-repairing function for scratches and wear of the surface of a friction part. When the surface modified nano metal oxide anti-wear self-repairing material is used for an engine, oil can be saved by15% or more, the engine noise is reduced by 15%, the material has functions of anti-wear and noise reduction and particularly can greatly reduce wear during cold start of an automobile and better protect the engine from cold wear; the oil change period is prolonged by one time or more (engine oil is replaced each time the automobile travels over 10000 to 15000 km), the catalytic oxidation of the lubricating oil through metal ions under high temperature is prevented, and the service life of the lubricating oil is prolonged.

Description

technical field [0001] The invention relates to an anti-wear self-repair material, in particular to a surface-modified nanometer metal oxide anti-wear self-repair material and a preparation method thereof, belonging to the field of polymer materials. Background technique [0002] Lubricating oil is called the blood of industry. Lubricating technology is the most effective anti-wear and anti-friction measure for mechanical systems. Improving the performance of lubricating oil and developing environmentally friendly new lubricating additives are inevitable to solve the increasing consumption of lubricating oil industry and protect the environment. need. In the 21st century, along with the development of modern industrial technology, industrial machinery and equipment continue to develop in the direction of high power, miniaturization, automation, high precision, increased power, improved efficiency, and increased reliability. Larger loads, higher temperatures and harsher envi...
