Problems solved by technology

This reaction may lead to surface aging
In addition, UV-sensitive photocatalysts can be activated even when irradiated by UV rays or sunlight, which limits their use and hinders their diversification and expanded applications.

Embodiment 1

[0045] 142 g of titanium tetraisopropoxide, 72 g of isopropanol, and 10 g of acetylacetone were reacted in the first reactor at room temperature for 30 minutes. 1.4 g of iron nitrate, 2.6 g of zinc nitrate and 1.8 g of copper nitrate were completely dissolved in 760 g of distilled water in the second reactor at 400 rpm. After slowly adding the reaction mixture in the first reactor to the aqueous solution in the second reactor, 1.6 g of nitric acid was added dropwise thereto. The resulting mixture was heated to 80°C and allowed to react for 3 hours. The reaction mixture was reacted with 7.6 g of triethylorthosilicate for 1 hour. The reaction yielded a transparent visible-light-active titanium dioxide photocatalyst.

[0046] The photocatalyst is sprayed at 1-20g / m 2 The amount coated on the wallpaper surface.

Abstract

The invention provides a wallpaper with the deodorizing function. The wallpaper comprises a base layer, a printing layer and an air cleaning coating formed in order from the bottom. The air cleaning coating is formed by coating a photocatalyst activated by the visible light. The photocatalyst contains a solvent, a titanium compound, a chelating agent, a metallic compound and an acidic catalyst. The invention also provides a method for manufacturing the wallpaper with the deodorizing function. Even in the presence of a low-energy light source such as an indoor filament lamp, a fluorescent lampand a light-emitting diode (LED) lamp, the wallpaper with the deodorizing function still continuously exhibits enough photocatalysis activity. Therefore, the wallpaper with the deodorizing function can be used in various occasions, including the place where no enough effect is achieved by the conventional wallpaper coated with the photocatalyst. In addition, the wallpaper with the deodorizing function can be used for a long term with no damage on the appearance of the base wallpaper.

Description

technical field [0001] The invention relates to an air-purifying wallpaper and a method for preparing the air-purifying wallpaper. More specifically, the present invention relates to an air-purifying wallpaper that can be used in low-energy light sources (such as indoor incandescent lamps and fluorescent lamps) and in high-energy light (such as ultraviolet rays) and a method for preparing the air-purifying wallpaper. and sunlight) showed sufficient photocatalytic activity. Background technique [0002] Many methods are known for imparting a deodorizing function to wallpaper. For example, applying porous adsorbents to wallpaper. The porous adsorbent is exposed on the surface of the wallpaper to exert its intended effect. In order to adhere the adsorbent to the wallpaper, a coating solution containing the adsorbent is applied to the wallpaper to form a surface coating. However, in this case, the binder clogs the pores of the adsorbent to hinder the deodorizing performance ...
