Example Embodiment
[0028] There are no special requirements for the preparation method of the high-temperature protective coating of the present invention, and various methods commonly used in the field can be used, as long as the components are uniformly mixed. However, the inventors of the present invention have discovered in research that the following methods are used to prepare high-temperature protective coatings, which can make the components mix more uniformly. The specific method is: under stirring, slowly add the oxidation protection agent to the water-soluble film-forming agent, when the amount of oxidation protection agent is added to half, start to slowly add 3-5% water, and make the oxidation protection agent and 3-5 Add the% water together, then add the curing agent, stir evenly, then add the dispersant, stir until the liquid is in a uniform and stable phase, then add the thickener, and add the remaining water after stirring evenly.
