PURPOSE: A paint composition is provided to enable the application to a laminate floor, plywood floor, and wood floor, to block the toxicity generated from cement, to prevent the noise and vibration generated between the up and down stairs of an apartment, and to improve the thermal ability of the building floor. CONSTITUTION: A paint composition for reducing inter-layer noise including porous alumina comprises 0.1~20 weight% of a ground mixture, 20~30 weight% of an aqueous ethylene vinyl acetate resin, 20~30 weight% of ion exchanged water, 25~40 weight% of calcium carbonate, 2~4 weight% of titanium dioxide, 0.1~1 weight% of ferric oxide, and 0.1~6 weight% of porous alumina. The ground mixture is made of a mineral ground material, wherein the mineral ground material comprises 50 ~ 96 weight% of an oyster shell ground compound processed at 1500-1600 °C and 1~20 weight% of the ground compound of aluminum oxides, potassium oxides, magnesium oxides, and calcium carbonates processed at 1100-1200 °C. |
