Description

technical field [0001] The invention belongs to the technical field of high-temperature-resistant materials, and in particular relates to a high-temperature-resistant fireproof coating and a preparation method thereof. Background technique [0002] 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. High temperature resistant coatings generally consist of high temperature resistant polymers, fillers, solvents and additives. Compared with other high-temperature oxidation and corrosion resistance methods, high-temperature-resistant coatings are easy to use and do not affect the normal performance of the protected object. With the rapid development of industries such as aviation, aerospa...
