POROUS CERAMIC INSULATION MATERIAL USING WASTE ALUMINUM DROSS POWDER AND METHOD FOR MANUFACTURING SAME

摘要

The present invention relates to a porous ceramic insulating material using waste aluminum dross powder and a method for manufacturing the same, and more particularly, to a soluble silicate; silicon powder; Waste aluminum dross powder surface-activated with an alkali solution and waste aluminum dross powder surface-activated with an acid solution; aluminum hydroxide; thickeners, dispersants and surfactants; quicklime; cement mixture; And it relates to a porous ceramic heat insulating material prepared by using the porous ceramic heat insulating material composition comprising a curing agent, and a method for manufacturing the same. According to the present invention, the present invention recycles fly ash and bottom ash, which are by-products generated in coal-fired power plants, recycles aluminum hydroxide used for artificial marble, and waste aluminum dross, which is a waste generated after recycling of automobile aluminum wheels. By using the powder, environmental pollution can be minimized, and a building material having excellent heat resistance, heat insulation and mechanical strength, that is, a porous ceramic insulation material can be provided at a low cost.
