PRODUCTION METHOD OF PHOTOCATALYST MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a production method of photocatalyst material which allows a photocatalyst layer to firmly adhere to base material and has excellent scratch resistance and weather resistance by using aqueous photocatalyst layer. SOLUTION: Hydroxy groups and/or alkoxy groups existing on the surface of silicone-based resin which is applied on the base material and peroxo groups and/or hydroxy groups existing on the surface of photocatalyst particles in an aqueous photocatalyst coating solution are reacted at a temperature of the heat-resistant temperature or lower of the base material or the silicone resin and, further, UV-ray of wavelength≤380 nm is applied thereto.
