Environment-friendly high-temperature-resistant paint and preparation method thereof

Abstract

The invention provides environment-friendly high-temperature-resistant paint, which is prepared from the following ingredients in parts by weight: 10 to 15 parts of silica sol, 15 to 20 parts of aluminium dihydrogen phosphate, 5 to 10 parts of glass powder, 5 to 10 parts of talcum powder, 10 to 15 parts of kaolin powder, 10 to 15 parts of aedelforsite powder, 1 to 5 parts of bis(cyclopentadienyl) ethoxyethyl acrylate and 20 to 30 parts of water. The invention also provides a preparation method of the environment-friendly high-temperature-resistant paint. All ingredients in the environment-friendly high-temperature-resistant paint are mutually matched; the advantages are complementary, so that on the premise of maintaining good attachment force of the paint, the paint has the excellent characteristics of corrosion resistance, high-temperature resistance, crack resistance, corrosion resistance, cold and heat exchange resistance, storage stability and the like.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to an environment-friendly 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, hig...

AI Technical Summary

Problems solved by technology

[0004] At present, there are many reports on heat-resistant coatings, and the temperature resistance of existing high-temperature-resistant coatings can basically meet the requirements for use, but there are some shortcomings.

For example, the surface drying time of the paint film is long, which will affect the appearance of the paint film due to dust and other reasons during use; most of the high-temperature resistant coatings on the market use hexavalent chromium as a corrosion inhibitor, which will cause great harm to the environment; corrosion resistance at high temperatures Disadvantages such as poor sex
