Method for coating photochemical catalyst composition on surface of article and article surface coating agent

Abstract

Provided is an article surface coating method for a photocatalyst composition capable of removing mal-odor in a room, a harmful substance or stain on the surface of an article by photocatalyst effect by coating the photocatalyst composition on the article surface of a plastic plate or a glass plate, and to obtain an article surface coating agent. The hotocatalyst composition 1, a binder 2 and a binder auxiliary agent 3 having an oily component are mixed to obtain the liquid article surface coating agent A. A coating film layer 4a obtained by thinly spreading the agent A on the surface of an article (b) is formed on the surface of the article (b). The binder and binder auxiliary agent in the outermost layer of the coating film layer are removed by wiping to expose the photocatalyst composition on the outermost layer surface of the coating film layer.

Description

technical field [0001] The present invention relates to an article surface coating method and an article of a photocatalyst composition capable of removing indoor odor, harmful substances, or surface pollutants of the above-mentioned article by applying the photocatalyst composition to the article surface such as a plastic plate and a glass plate. surface coating agent. Background technique [0002] It is known in the prior art that pollutants floating in the air such as indoors are removed by coating a photocatalyst on the glass surface of a building. [0003] Patent Document 1 [0004] Japanese Patent Laid-Open Publication No. 9-173783 [0005] Among them, since the binder contains a photocatalyst composed of titanium dioxide or a mixture of titanium dioxide and activated carbon, or spreads the photocatalyst on the binder, so that the photocatalyst is exposed to the outside of the binder, the post-treatment is carried out by heating A heat source such as a heat source h...

Problems solved by technology

[0006] However, this prior art photocatalyst is contained in adhesives such as adhesives and is fixed by heat treatment. Therefore, for example, in order to coat the photocatalyst on the window glass of existing or newly built houses, offices, etc., it is necessary to No one can easily implement large-scale equipment such as heaters and other heat treatment devices, and it is also impossible to obtain sufficient photocatalytic effects
