The invention provides a boiler water cooling wall high-temperature anti-corrosion anti-staining anti-slagging ceramic coating material, a preparation method and applications thereof, and belongs to the technical field of special coating materials, wherein the ceramic coating material comprises, by mass, 45-51.2% of a filler, 35% of a binder, 5.22% of an additive, 1.22% of an auxiliary agent, andthe balance of water, and the filler comprises 27.5% of synthetic mullite, 9.9% of corundum powder, 1.5-2.7% of pure calcium aluminate micro-powder, 1.9-4.5% of active alumina micro-powder, 1.8-3.6 ofsilicon micro-powder, and 3% of a rare earth oxide. The preparation method comprises: adding water to a binder, mixing to obtain a binder liquid, carrying out grinding refining treatment on a fillerto achieve a particle size of less than or equal to 5 [mu]m, adding the treated filler into the binder liquid, adding an auxiliary agent, uniformly stirring, filtering, and encapsulating. According tothe present invention, the outer surfaces of boiler water cooling wall furnace pipes and heating furnace pipes can be coated with the obtained coating material to form ceramic coatings.
