Photocatalytic coating material, photocatalytic composite material and process for producing the same, self-cleaning water-based coating comopsitions, and self-cleaning member

摘要

The photocatalytic coating agent of the present invention contains at least (a) a photocatalytic oxide particle, (b) a hydrophobic resin emulsion, and (c) water, and the average particle diameter of the photocatalytic oxide particle is an average particle diameter of particles dispersed in the hydrophobic resin emulsion. It is smaller than. In addition, the self-cleaning water-based coating composition contains (b) photocatalyst particles or photocatalyst sol, (c) water, such as (a) silicone aqueous emulsion, and solid content of (b) component is less than 5 weight of the total solid of paint. Furthermore, a self-purifying aqueous coating composition comprising (a) a silicone aqueous emulsion, (b) a whisker and the like, (c) a photocatalyst particle, (d) an inorganic colored pigment, and (e) water is also provided.
