常温硬化性高活性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 JP5874267
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a photocatalyst coating solution which can form a hydrophilic thin film having a good pot life, good coating performance, ability of being dried and cured at ordinary temperatures, high transparency and long duration of catalyst activity.SOLUTION: The photocatalyst coating solution contains (A) a photocatalyst particle, (B) a binder component, and (C) a water-soluble Lewis acid compound, wherein the binder component (B) includes a hydrolysis condensate obtained by hydrolyzing (b-1) a hydrolyzable silicon compound in a mixed solvent of water and a polar organic solvent, in the presence of a basic compound; the component (A), i.e. the photocatalyst particle, is dispersed in the coating solution; the ratio of the component (A) to the total of component (A) and component (B) is 0.05-99.5 mass%; the ratio of the component (C), i.e. a water-soluble Lewis acid compound, to the component (B), i.e. the binder component, is 0.01-50 mass%; and pH of the coating solution is in a range of 5-8.
