PURPOSE : A method for manufacturing an inorganic wall material for building interiors and exteriors is provided to emit large amounts of far infrared rays and anions, and adsorb and remove volatile organic compounds or an odor. CONSTITUTION : A method for manufacturing an inorganic wall material for building interiors and exteriors includes the steps of : charging 20-40%% of cement, 20-40%% of gypsum, 10-30%% of quartz sand, 5-10%% of vermiculite, 10-35%% of clay, and 10-35%% of white earth into a mixer, and stirring the materials while adding water to increase the total weight of the materials by 3-8%%, wherein each of the materials has an average particle size of 1.2 mm or smaller; placing the obtained mixture in an aging room having an internal temperature of 10-35 °C, and aging the mixture for 2-3 hours to have viscosity suitable for forming the mixture; supplying the aged mixture to a press molding machine to produce a molded product, wherein the press molding machine is operated at a discharge pressure of 200-400 kg/cm^2; supplying water to the upside and underside of the molded product to increase the weight of the molded product by 15-30%%; and curing the molded product in a curing room. © KIPO 2008
