Lubricating oil and application thereof

Abstract

The invention discloses a lubricating oil, and belongs to the technical field of chemical engineering. The lubricating oil is used to solve the problems of short service life of present lubricating oils having poor lubrication and anti-wear effects, and high device maintenance cost caused by unable meeting of healthy and stable running of relevant running devices. The lubricating oil comprises a lubricating carrier oil and a copper-based composite powder material uniformly dispersed in the common lubricating carrier oil, a mass ratio of the copper-based composite powder material to the common lubricating carrier oil is 0.01-10:100, and the particle size of the copper-based composite powder material is 0.01-10[mu]m. The invention also provides an application of the lubricating oil in automatic repairing of the worn surfaces of machines. The lubricating oil also has the advantages of strong adhesion, improved anti-wear protection property, improved anticorrosive property, improved self-cleaning property, improved adhesive sealing property, improved vibration damping property and good cooling effect, so the service life of the machines is prolonged, and the maintenance cost is reduced.

Description

[0001] This application claims the priority of Chinese patent application numbers 2014106917067, 2014106881065, 2014106899459, 2014106905962, 2014106881084 and 2014106905159 filed on November 25, 2014. technical field [0002] The invention belongs to the technical field of chemical industry, and relates to a lubricating oil.

Problems solved by technology

[0005] However, the current lubricating oil used on the mechanical working surface has the following problems: the adhesion stability between the general lubricating oil and the mechanical working surface is poor, resulting in poor stability of the formed oil film, and the surface of the friction pair is lubricated, anti-wear, anti-corrosion, and self-cleaning. , Adhesive seal, poor cushioning and vibration reduction effect, causing the surface of the mechanical friction pair to wear easily, especially the poor thermal conductivity of the current lubricating oil, which affects the cooling effect of high-temperature working equipment

Many of the above problems can significantly affect the working efficiency of mechanical equipment, increase maintenance frequency and equipment maintenance costs, so the current application performance of lubricating oil still needs further improvement, such as the ability of lubricating oil to automatically repair mechanical wear and scars
