ANTIBACTERIAL PHOTOCATALYTIC COATING MATERIAL AND ANTIBACTERIAL PHOTOCATALYTIC MEMBER |
| 摘要 |
PROBLEM TO BE SOLVED: To obtain a cold curable antibacterial photocatalytic coating material having an antibacterial effect and excellent in hot water resistance and alkali resistance by mixing a coating material with a photocatalyst which comprises a low-cost oxide and exhibits a photocatalytic activity in a visible light region, and to provide an antibacterial photocatalytic member. SOLUTION: The antibacterial photocatalytic coating material contains an acrylic silicone coating material, an organic solvent and a photocatalyst, wherein the photocatalyst is represented by the constitutional formula (I): A2- XB2+ XO8-2δ(provided that -0.4<X<+0.6 and -0.5<2δ<+0.5), and comprises an oxide with a pyrochlore-related structure in which an oxygen ion is inserted into at least one oxygen deficit position and an interstitial position in view of the fluorite structure of a pyrochlore-type oxide of the constitutional formula (II): A2- X<3+> B2+ X<4+> O7+( X/2)+ Y (provided that -0.4<X<+0.6 and -0.2<Y<+0.2) wherein the ions A and the ions B possibly having plural ionic valences are orderly arranged. An antibacterial photocatalytic base material is obtained by using this coating material.
