Abstract

The invention discloses an inorganic high-temperature-resistant ceramic wear-resistant anticorrosive coating and a preparation method thereof. The coating is prepared from the following raw materials in parts by weight: 50-70 parts of inorganic silicon resin, 3-10 parts of titanium dioxide, 3-10 parts of mica iron red powder, 1-5 parts of tungsten powder, 5-15 parts of modified silicon carbide, 5-15 parts of phosphate and 2 parts of a wetting dispersant. According to the inorganic high-temperature-resistant ceramic wear-resistant anticorrosive coating disclosed by the invention, phosphate is added, and the content of each component is changed, so that the salt water resistance of the obtained coating is remarkably improved. In the preparation method of the inorganic high-temperature-resistant ceramic wear-resistant anticorrosive coating, a certain amount of phosphate is added into the modified silicon carbide, so that the salt water resistance of the coating is unexpected.

Description

technical field [0001] The invention belongs to the technical field of painting, and in particular relates to an inorganic high-temperature-resistant ceramic wear-resistant and anti-corrosion paint and a preparation method thereof. Background technique [0002] High-temperature anti-rust paints for iron and steel building materials such as automobiles, aircraft engines and exhaust pipes, aircraft, ship motors, and high-temperature material transmission pipes are mainly divided into two categories: physical coverage and electrochemical anti-corrosion according to the anti-rust mechanism. The former relies on the film-forming base material and inorganic fillers, anti-rust pigments, etc., such as mica, graphite, silicon carbide, iron red, zinc oxide, phosphate, etc., to form a dense paint film to prevent corrosive substances in the environment. The intrusion of the latter; the chemical anti-rust effect of the latter, adding phosphate and ferrous components in iron red, aluminum...
