Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a 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-temperature pipes, h...
