no. 1 approach

[0027] The photocatalyst coating agent of the present embodiment includes: a dispersion medium containing water; photocatalyst fine particles dispersed in the dispersion medium; and silver ions. The concentration of the silver ion in the photocatalyst coating agent is 0.6 ppm or more.

[0028] A photocatalyst coating agent (photocatalyst coating liquid) is a suspension in which photocatalyst fine particles are dispersed in an aqueous dispersion medium, and is a coating agent for forming a photocatalyst layer on the surface of a substrate. The photocatalyst coating agent can also be packed in a storage container, a storage container, a spray bottle, or a spray product.

[0029] The method for coating the photocatalyst coating agent on the substrate surface is not particularly limited, but the method is, for example, spray coating, dip coating, screen printing, spin coating, brushing, roll coating, and roll coating (roll coating). coating) etc.

no. 2 approach

[0049] The second embodiment relates to spray preparations. figure 1 It is a schematic sectional view of the spray product of this embodiment.

[0050] The spray product 20 includes the photocatalyst coating agent 2 of the first embodiment and the sprayer 3 configured to spray the photocatalyst coating agent 2 .

[0051] The sprayer 3 may include a trigger spray structure, the trigger spray structure is a pull trigger 11, the photocatalyst coating agent 2 in the chamber 8 is pressed by the plunger 10, and the photocatalyst coating agent is sprayed from the spray nozzle 9 2.

[0052] Preparation experiment of photocatalyst coating agent

Embodiment 1

[0055] Mix the slurry 2.3g, water 97.6g and composite agent 4mg (silver ion 0.06mg) of the photocatalyst microparticle dispersion of volume average particle diameter D50=200nm by the ratio of 21wt%, prepared photocatalyst coating agent 100ml, so 4 mg of the above-mentioned composite agent is a composite agent in which 1.5 wt % of silver ions are supported on zeolite fine particles. In photocatalyst microparticles, Pt-supported WO is used 3 powder.

Abstract

The present invention provides a photocatalytic coating material which contains: a dispersion medium containing water; photocatalytic fine particles dispersed in the dispersion medium; and silver ions, a concentration of the silver ions of the photocatalytic coating material is 0.6 ppm or more.

Description

technical field [0001] The present invention relates to a photocatalyst coating agent and a spray product. Background technique [0002] Generally used photocatalyst coating agents are mixed with bacteria and mold in the air during the production process, use, etc., and multiply. In order to prevent mildew and spoilage in the liquid caused by long-term storage, preservatives are usually added. As a material having an anti-corrosion effect, a photocatalyst coating agent in which ethanol is added is commercialized. [0003] However, there are people who react with ethanol to cause allergies and dry skin, so consumers demand products with no ethanol or low ethanol concentration. [0004] On the other hand, a photocatalyst-coated body including photocatalyst particles carrying antimicrobial metal particles is known (for example, refer to Patent Document 1).
