PHOTOCATALYST TITANIUM OXIDE SOL, AND COATING COMPOSITION AND MEMBER UTILIZING THE SAME |
摘要 |
<p>The object of the present invention is to provide a photocatalytic titanium oxide sol which presents antibacterial properties in a dark place, and, in particular, relates to a photocatalytic titanium oxide sol which is stable and causes no discoloration by light even though containing silver, and relates to a coating composition and a member using the same. The photocatalytic titanium oxide sol according to the present invention is characterized by including silver, copper and a quaternary ammonium hydroxide. The photocatalytic coating composition has the photocatalytic titanium oxide sol dispersed in a binder. Furthermore, the member includes coating the surface of a substrate with the photocatalytic coating composition. The photocatalyst titanium oxide sol according to the present invention can contain highly antibacterial silver by skillfully utilizing copper and a quaternary ammonium hydroxide, and accordingly can show an antibacterial effect not only in a dark place simply due to silver, but also a higher antibacterial effect in a conventional application of employing ultraviolet sterilization by concomitantly using the photocatalyst titanium oxide sol according to the present invention and an ultraviolet sterilizer.</p> |
