PURPOSE: A sheet of wallpaper containing multi-wall carbon nanotube is provided to block toxicity generate from cement and to block noise and vibration between floors in an apartment. CONSTITUTION: A sheet of wallpaper for reducing noise between floors in a building is coated with paint containing 0.1-20 wt% of pulverized mixture, 20-30 wt% of aqueous ethylene vinyl acetate(EVA) resin, 20-30 wt% of ion-exchanged water, 25-40 wt% of calcium carbonate, 2-4 wt% of titanium dioxide, 0.1-1 wt% of iron oxide, and 0.1-4 wt% of multi-wall carbon nanotube. The pulverized mixture contains 50-96 wt% of oyster shell pulverized matter, and 1-20 wt% each of aluminum oxide, potassium oxide, magnesium oxide, and calcium carbonate. The average radius of the paint is 0.2-1 um. |
