Abstract

The invention relates to an anti-wear self-healing material which is synthesized in situ by surface-modified nano hydroxysilicate and boride and a preparation method of the anti-wear self-healing material. Composite particles which combine a hard phase and a soft phase are formed in situ by compounding nano silicate and boride, therefore, the performance advantages of the two are brought into play, and complementation of the advantages is achieved, so that the material has the dual functions of abrasion resistance and wear reduction and wear self healing, and a synergistic effect and a disadvantage complementing mechanism of different types of the nano materials are brought into play. Through the anti-wear self-healing material, a breakthrough of multiplied increase of extreme-pressure anti-wear performance is achieved, zero wear of metal friction is broke through under the condition of extreme pressure, and real super lubrication is achieved under the condition of extreme pressure; since no corrosive organothiophosphorous compounds are included in the material, not only can the anti-wear performance be improved, but also the wear-reducing and energy-saving performance can also beimproved.

Description

technical field [0001] The invention relates to an anti-wear self-repairing material, in particular to an anti-wear self-repairing material synthesized in situ by surface-modified nano-hydroxysilicate and boride 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.
