step two: uniformly spraying the water-based paint of the bottom coating on the heating surface of the waste incineration boiler through a spray gun, uniformly laying short carbon fibers when the water-based paint of the bottom coating is not completely dried, and preparing a buffer layer when the short carbon fibers are laid until the bottom coating is fully paved and the short carbon fibers cannot be bonded;
step three: adding deionized water and an auxiliary agent in a proportion in the surface coating into a stirring barrel for stirring and mixing, then adding an oxide, water glass and graphene, stirring and defoaming or vacuum defoaming, and then adding a curing agent to obtain a surface coating water-based paint for later use;
step four: and (3) uniformly spraying the prepared water-based paint for the top coating on the surface of the buffer layer in the third step by a spray gun until the buffer layer is completely covered.
