Title:
光触媒塗工液及びそれから得られる光触媒薄膜
Document Type and Number:
Japanese Patent JP5874266
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a photocatalyst coating liquid good in pot life and coatability, dryable and curable at a relatively low temperature, and capable of forming a hydrophilic thin film high in transparency and long in the duration of the catalytic activity.SOLUTION: The photocatalyst coating liquid contains (A) a photocatalyst particle, and (B) a binder component, wherein the binder component as the (B) component contains a hydrolytically condensed substance obtained by hydrolyzing a hydrolyzable silicon compound in the presence of a basic compound in a mixed solvent of water and a polar organic solvent; the photocatalyst particle as the (A) component is dispersed in the coating liquid; the proportion of the (A) component to the total of the (A) component and the (B) component is 0.05 to 99.5 mass%; and the pH of the coating liquid is in the range of 5 to 8.
