BUILDING MATERIAL FOR EXTERIOR WALL

Document Type and Number:

Japanese Patent JP3465664

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a building material for an exterior wall having self- cleaning properties and easily cleanable properties.
SOLUTION: The building material for the exterior wall has a surface layer containing photocatalytic oxide particles on the surface of a building-material base body for the exterior wall, the surface layer can be manufactured by forming an amorphous titanium oxide layer on the surface of the base body, baking the amorphous titanium oxide layer at a temperature higher than the crystallization of anatase and phase-changing amorphous titanium oxide into anatase type titanium oxide, the building material displays a hydrophilic nature of 10° or less by conversion into a contact angle with water in response to the photo-excitation of the photocatalytic oxide particles, and an adhesive deposit or a contaminant is washed away by rain drops or washed easily with water when the surface of the building material for the exterior wall is exposed to a rainfall.
