PHOTOCATALYTIC COATING MATERIAL AND METHOD FOR PRODUCING THE SAME AND PHOTOCATALYTIC COATED FILM WITH PHOTOCATALYTIC FUNCTION OBTAINED BY COATING THE MATERIAL AND MULTILAYERED PHOTOCATALYTIC COATED FILM

摘要

PROBLEM TO BE SOLVED: To provide a photocatalytic coating material excellent in transparency, hardness and decomposing performance and a method for producing the same and to provide a photocatalytic coated film having photocatalytic function obtained by coating the coating material.;SOLUTION: The photocatalytic coating material relates to improvement of the photocatalytic coating material containing titanium oxide powder and is characterized by the fact that the titanium oxide powder includes an anatase-type crystal structure wherein the interplanar spacing d value of the (101) plane of the anatase-type crystal obtained from the half-width of the diffraction peak of the (101) plane is 3.478 to 3.562Å. And the photocatalytic coating material comprises titanium oxide powder, aluminum oxide powder, a binder, a dispersing agent and a dispersant.;COPYRIGHT: (C)2004,JPO
