Abrasion-resistant coatingfor door and preparation method thereof

Abstract

The invention discloses anabrasion-resistant coating for a door. The abrasion-resistant coating for door is prepared from, by weight, 45-50parts ofpolyester resin, 16-20 parts ofmolybdenum disulfide, 24-30parts ofgraphite powder, 9-15parts ofcopper oxide powder, 23-28 parts ofquartz powder, 7-10 parts ofmica powder, 5-10 parts ofreduced iron powder, 22-25parts ofsodium tetraborate, 1-5 parts ofcalcium dihydrogen phosphate, 4-7 parts of paraffin wax, 6-10 parts ofphosphate, 13-18parts offluorine oil, 7-20parts of sodium carboxymethylcellulose, 6-8 parts of polyacrylamide, 9-12parts ofcitric acid, 23-28parts ofsilane coupling agent, 35-40parts oftitanium dioxide, 2-10 parts ofcarbon black, 6-8parts oflithopone, 12-17 parts ofpolyvinyl alcohol and 16-20 parts ofcellulose sodium. The abrasion-resistant coating has a dehumidification function and good adhesion and meanwhile has a good abrasion resistance effect and long service life.

Description

technical field [0001] The invention relates to a door wear-resistant coating and a preparation method thereof. Background technique [0002] Wear-resistant coatings are a new type of functional coatings with special functions, which have good wear resistance. For example, anti-wear coatings are coated on glass and lenses, and the glass and lenses will no longer have scratches. The mechanical industry adopts wear-resistant functional coating technology to coat the metal surface of key mechanical parts, which can improve the wear resistance, hardness and service life of mechanical equipment. With the development of modern science and technology, artificial satellites, spacecraft, high-speed trains, impellers of steam turbines and engines, propellers of ships, blades of hydroelectric generators, decks of ships, floors of buildings, road marking paint, etc. The high-speed airflow, the erosion of sand and water, and the action of mechanical force, the wear of the material is q...

AI Technical Summary

Problems solved by technology

Comparison of high-temperature wear-resistant coatings and wear-resistant ceramic sheets: Compared with high-temperature wear-resistant coatings in terms of wear resistance, ceramic sheets are easy to fall off due to defects in the pasting process

The disadvantages of the pasting process are: first, in the production process, it is necessary to derust the surface, roughen it, clean it with acetone, prepare epoxy resin glue, and then paste it; secondly, the ceramic sheet is easy to fall off when it collides during transportation and installation. Add effort to installation

[0004] At present, the existing wear-resistant coatings do not have dehumidification function, poor adhesion, and do not have good wear-resistant effect, and the service life is not long
