Description

technical field [0001] The present invention relates to a coating. Background technique [0002] High temperature resistant coatings refer to coating materials that can maintain proper physical and mechanical properties without discoloration or falling off of the paint film at a temperature above 200°C. High temperature resistant coatings are widely used in chimneys, high temperature steam pipes, heat exchangers, high temperature furnaces, petroleum cracking equipment, engine parts and exhaust pipes, etc. With the rapid development of aviation, aerospace, weapons and other industries, the demand for high-temperature resistance of special components is getting higher and higher. High-temperature-resistant coating materials have gradually attracted the attention of the world due to their good performance in large-scale construction processes and no large-scale shedding. attention of scholars from all over the world. There are many types of heat-resistant coatings, but silico...
