Abstract

The invention relates to the field of materials, in particular to a magnesium silicate nanotube anti-wear material doped with organic silicon. The material is prepared by doping an organic silicon material into a hydroxyl magnesium silicate nanotube according to the mass concentration of 1: 30-50 to form the hydroxyl magnesium silicate anti-wear nano material doped with the organic silicon, wherein the hydroxyl magnesium silicate nanotube is obtained by heating a magnesium compound containing magnesium element and a silicon compound containing silicon element in an alkali solution for reaction, and then centrifuging, washing and drying in sequence. The hydroxyl magnesium silicate nanotube anti-wear material doped with the organic silicon is in a nanotube shape, has a tube diameter of 15-55nanometers and a length of 100 nanometers to 5 micrometers, and has relatively regular products, uniform fineness and even dispersion. As an additive of lubricating oil, the anti-wear and anti-friction performance of lubricating oil can be greatly improved, the lubricating function is excellent, and the service life of mechanical equipment is prolonged.

Description

technical field [0001] The invention relates to the field of materials, in particular to an organosilicon-doped magnesium hydroxysilicate nanotube anti-wear material and a preparation method thereof. Background technique [0002] During the operation of mechanical equipment, friction phenomena widely exist, and the wear caused by friction is the main reason for the failure of mechanical equipment. About 80% of the parts are damaged due to various forms of wear. Lubricating oil can reduce friction and reduce wear. However, in actual working conditions, the base lubricating oil and some synthetic products often cannot meet the high performance requirements required by the application. People still need to continuously develop and select various compounds with special properties to add to the lubricating oil in order to give full play to their excellent performance. lubricating properties. People usually use graphite, molybdenum disulfide and nano-copper as additives to add t...
