Water-soluble high-temperature-resistant coating and preparation method thereof

Abstract

The invention provides a water-soluble high-temperature-resistant coating. The water-soluble high-temperature-resistant coating comprises, by weight, 8-12 parts of aluminum sol, 15-20 parts of aluminum dihydrogen phosphate, 8-14 parts of ground glass, 5-10 parts of talcum powder, 10-15 parts of kaolin powder, 10-15 parts of wollastonite powder, 1-5 parts of dicyclopenteneoxyethyl acrylate and 20-30 parts of water. The invention also discloses a preparation method of the water-soluble high-temperature-resistant coating. With all components in the water-soluble high-temperature-resistant coating matched mutually and complementing mutual advantages, the water-soluble high-temperature-resistant coating has the advantages of excellent corrosion prevention performance, resistance to high temperature and cracking, thermal shock resistance, good storage stability and the like on the premise of keeping good adhesive force.

Description

technical field

[0001] The invention belongs to the technical field of coatings, in particular to a water-soluble high-temperature resistant coating and a preparation method thereof. Background technique

[0002] With the rapid development of modern industry and national defense construction (such as aerospace, aviation, weapons, etc.), the requirements for high-temperature resistant coatings for equipment are getting higher and higher. Physical and mechanical properties and anti-corrosion properties.

[0003] High temperature resistant coatings, also known as heat resistant coatings, generally refer to coatings that can maintain proper physical and mechanical properties without discoloration or falling off of the paint film above 200°C, so that the protected objects can function normally in high temperature environments Special functional coatings. Therefore, high-temperature resistant coatings are widely used in high-temperature places such as steel chimneys, high-temper...
