High-temperature anti-corrosion coating material, and usage method and application thereof
The invention discloses a high-temperature anti-corrosion coating material, and a usage method and application thereof. The high-temperature anti-corrosion coating material is prepared by mixing an anti-corrosion powder and a colloid according to a weight ratio of 1:1-1:2, wherein the anti-corrosion powder is prepared by mixing magnesium aluminate spinel powder and white corundum powder, the magnesium aluminate spinel powder accounts for 70%-97% by weight of the anti-corrosion powder and white corundum powder accounts for 2%-30% by weight of the anti-corrosion powder; and the colloid is modified alumina sol or modified zirconia sol. The provided coating material possesses the advantages of compact structure, high surface strength, resistance to high temperature, good corrosion resistance and the like, is strong in combination capability with a matrix, good in thermal shock resistance, and not easy to fall off, and is applicable to coat the furnace lining surface of an industrial kiln as a refractory material of a hearth heated surface.
