The invention discloses a preparation method of a photocatalytic antibacterial porous adsorption air purification coating. The invention first mixes an adsorption material, a light guide material and a photocatalyst, and then sprays it on the surface of a substrate to form an adsorption function and a rough, porous and conductive coating. Light-adsorbing light-guiding coating, which is characterized by adsorption function, light-guiding and porous properties, which is conducive to the reflection or transmission of light in the coating and disperses in the inner space of the coating. The light-guiding materials nano-silica and liquid silica gel Introduced into adsorbents such as activated carbon and shell powder. In addition, aluminum particles have a scattering effect on light. Combined with photocatalyst, the light entering the layer can reach the surface of the photocatalyst inside the carrier through light transmission or reflection in the adsorbed porous carrier for photocatalytic reaction. . |
