Problems solved by technology

Most of the above products have the following problems: (1) In the pure oil medium, the friction coefficient is not less than 0.003, and it is greater than 0.003 under dry friction conditions, and even loses its due effect; (2) Poor high temperature resistance, it is difficult to break through 900°C limit; (3) It cannot work in high temperature, marine environment and strong acid-base medium, especially after modification, an obvious interface layer or oil film is formed on the surface of the friction pair, making it difficult for the surface roughness of the material to exceed grade 14; (4) Although it can achieve good results in anti-wear and anti-friction effects, it is limited by the scope of application; (5) In terms of the repair function of worn wounds, the design size cannot be maintained for a long time, and only a few nanometers Worn surfaces at depths below have a restorative effect
Due to the simple addition of nano-silica, it is difficult to form an effective nano-film, and it can only repair the local friction surface

Abstract

The invention relates to a nanometer restoration agent that could take automatic repairing to the worn-out surface of mechanic device attrite set using lubricant as carrier, and the manufacture method. It contains 0.1-5wt% nanometer additive, the basal material is lubricant, which is made up from 18-33% SiO2, 21-40% Al2O3, and 31-55% MgO. The manufacture method adopts ultrasound smashing method. It has good stability, little frictional coefficient, strong drive ability, low oil consumption, and low oil fume discharging.

Description

(1) Technical field [0001] The invention relates to a nanometer repairing agent which uses lubricating oil as a carrier and can automatically repair the worn surface of friction pairs of mechanical equipment, and a preparation method of the repairing agent. (2) Background technology [0002] At present, nanometer has been widely used, such as in the field of machinery, the use of nanomaterials to optimize the performance of metal surfaces, increase the wear resistance of metal surfaces, reduce friction coefficients, and automatically repair the worn surfaces of friction pairs. The foreign patented production uses positive and negative electrons to form a protective layer that attracts each other between the friction pairs, which reduces friction loss and has poor welding performance with the substrate. The protective layer can only be formed when the mechanical equipment is running; the product is mainly composed of hydrocarbons. It is the heat energy generated during the op...
