Photocatalytic concrete material sprayed with titanium dioxide/activated zeolite composite material and preparation method thereof

摘要

The present invention provides a photocatalytic concrete material sprayed with titanium dioxide/activated zeolite composite material and preparation method thereof, and the photocatalytic concrete material sprayed with titanium dioxide/activated zeolite composite material comprises following raw materials in parts by weight titanium dioxide 0.1-20 parts, activated zeolite molecular sieve 0.1-20 parts, dispersant 0.1-5 parts, emulsifier 0.05-2 parts, coupling agent 0.05-2 parts, cement 40-90 parts, fine sand 40-90 parts and water. In the present invention, the activated zeolite molecular sieve can load titanium dioxide photocatalytic material as a carrier, and can easily adsorb gaseous pollutant of automobile exhaust with huge specific surface area (280.1 m²/g), thereby increasing photocatalytic degradation efficiency and the efficiency can reach 92%, besides, the present invention has advantages of simple preparation technology, cheap raw materials and low preparation cost, so the present invention is suitable for industrial production.
