MATERIAL AND EXECUTION METHOD FOR PHOTOCATALYTIC ROAD MARKING OBJECT, AND PHOTOCATALYTIC ROAD MAKING OBJECT

摘要

PROBLEM TO BE SOLVED: To provide a photocatalytic road marking object having no interference colors, and a method in which the photocatalytic road marking object, conventionally formed by being heated at a high temperature, is formed on a road surface at an approximately ordinary temperature.

SOLUTION: A material for the photocatalytic road marking object includes: a titanium oxide sol solution containing amorphous titanium oxide which is obtained by making hydrogen peroxide act on titanium hydroxide gel prepared from a basic solution containing a titanium compound; an organic substance; and a solvent or a disperse medium. Preferably, the organic substance is polyethylene oxide polymer-modified polydimethylsiloxane or polyethylene oxide polypropylene oxide block copolymer-modified polydimethylsiloxane.
