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 coating for high-temperature equipment and a preparation method thereof. Background technique [0002] With the rapid development of social economy and the improvement of people's living standards, industrial equipment and civilian electrical appliances have also put forward higher requirements for the coatings used. Many occasions in industry require equipment capable of heat conduction and heat resistance, such as heat exchangers; many electrical appliances and equipment also require equipment to be able to insulate, heat transfer, and withstand high temperatures. [0003] High temperature resistant coating refers to the coating material that the temperature is above 200 ℃, the paint film does not change color, does not fall off, and can still maintain appropriate physical and mechanical properties. High tem...
