Abstract

PROBLEM TO BE SOLVED: To obtain a material having antibacterial activity, preventing the removal of Cu and Ag and making germ direct contact with the exposed part by supporting Cu or Ag so as to be partly exposed to the surface of the material via a binder. SOLUTION: The material having antibacterial activity is obtained by applying a glaze 2 which is a material scarcely decomposed by the photocatalytic action of a photocatalyst particle, on the surface of a tile material 1 for example, sheet material composing wall surface, floor face or ceiling plane, spraying an anatase type TiO2 particle in sol form including Cu and Ag or the like as the photocatalyst with a spray or the like on the surface of the glaze layer 2, and cooling and solidifying the glaze layer 2 after heating and melting. The antibacterial material having antibacterial action with fixed Cu and Ag or the like, is obtained by heating the TiO2 sol at 300 to 900 deg.C after spraying to the surface of the glaze layer 2 following the preceding description.

2. Description of the Related Art Anatase-type TiO2 is known as a photocatalyst for promoting a deodorizing reaction upon irradiation with ultraviolet rays. The applicant has proposed a proposal in which the raw material obtained by kneading the photocatalyst particles into a binder is applied to the surface of the member constituting the wall surface of the living space and then fired, so that the wall surface of the living space has a deodorizing wall function. I have done it first.

In the prior art, since the photocatalyst particles 102 are completely buried in the binder layer 101, the entire deodorizing wall does not directly irradiate all the photocatalyst particles 102 with ultraviolet rays. The particle size is relatively large, and a sufficient catalytic action cannot be exhibited. This is also true when Cu or Ag having a sterilizing function is blended in the binder layer instead of the photocatalytic particles having the deodorizing function.
