Title:
【発明の名称】光触媒活性及び耐光性に優れた光触媒被覆複合部材及びその製造方法
Document Type and Number:
Japanese Patent JP3371104
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a photocatalyst-coated composite member which is improved in photocatalytic activity and excellent in light resistance and in which the decomposition of a coating film used as a binder is controlled. SOLUTION: A photocatalyst coating film 3 in which photocatalyst particles coated with zeolite are dispersed is formed on a base material directly or through a primer layer 2. The photocatalyst particles 4 are coated with zeolite films 5, for example, 5 nm-5 μm in thickness and dispersed in the coating film 3 in a ratio of 5-80 mass%. Metal, glass, tile, a synthetic resin, a particle board, gypsum, cocrete, or the like, are used for the base material 1. The photocatalyst coating film 3 is formed by applying an organic resin coating material containing the photocatalyst particles 4 coated with the zeolite films 5 on a primer coating film and heat-treating the coating.
