Title:
PAINT COMPOSITE FILM COMPRISING ANATASE-TYPE TITANIUM OXIDE, AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2016/148108
Kind Code:
A3
Abstract:
Provided is a paint composite film which comprises anatase-type titanium oxide, exhibits photocatalytic activity and generates active oxygen even in visible light and weak light rays, has a self-cleaning effect, and effectively blocks the invasive action of activated oxygen on interior surfaces. Also provided is a method for manufacturing the paint composite film comprising anatase-type titanium oxide. The present invention, in which a peroxotitanic acid solution serves as an A solution and an anatase-type titanium oxide dispersion solution obtained by heating the A solution to 70-200°C serves as a B solution, is characterized by providing: an exterior-use composite film having a photocatalyst layer and obtained by applying and drying the B solution, which has photocatalytic activity, on an undercoat layer formed by applying and drying the A solution, to which reinforcing particles have been added; and an interior-use composite film having antimicrobial activity even in dark places and obtained by applying and drying the B solution, to which a precious metal has been added, on an undercoat layer formed by applying and drying the A solution.
