Problems solved by technology

[0004] At present, wear-resistant coatings mostly use thermal spraying technology or sintering to form a film. Both of these methods consume a lot of energy and are harmful to operators, and they cannot be used on surfaces that cannot withstand high temperatures.

Abstract

The invention relates to a normal-temperature solidifying wear-resistance coating and a preparation method thereof. The normal-temperature solidifying wear-resistance coating consists of a component A and a component B, which are in a weight ratio of (7-12):1, wherein the component A consists of graphite fluoride, silicon carbide micropowder, fluorinated ethylene vinyl ether (FEVE) fluorocarbon resin, a first solvent, a dispersant, a coupling agent and a thixotropic agent; and the component B comprises a solidifying agent and a second solvent. The normal-temperature solidifying wear-resistance coating can be applied by the conventional brushing, dipping and spraying coating processes without consuming a large amount of energy and can be applied on surfaces susceptible to high temperature. And with the high hardness and high wear resistance of silicon carbide and the excellent lubricating performance of graphite fluoride, the normal-temperature solidifying wear-resistance coating has the characteristics of high hardness and high wear resistance. In addition, the normal-temperature solidifying wear-resistance coating has high heat resistance and can solidify at normal temperature or solidify quickly with heating.

Description

technical field [0001] The invention belongs to the technical field of material surface protection, and in particular relates to a normal-temperature curing wear-resistant coating with good wear resistance and high hardness and a preparation method thereof, which can be used in aluminum materials, copper materials, and other places requiring wear-resistant coatings. Background technique [0002] 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 water wheel engines, decks of ships, floors of buildings, road marking paint, etc., are all subject to high-speed The erosion of airflow, sand and water and the action of mechanical force will cause serious wear and tear on the material. In order to prolong the service life, the surface of the material needs to be coated with wear-resistant paint. [0003] Abrasion-resistant coating is a kind of coating wi...
