manufacture example 1

[0038] Manufacturing example 1 (manufacturing of photocatalyst paint)

[0039] 10 wt. of ethyl acetoacetate was mixed into 50 wt. wt. of aqueous anatase sol to obtain a photocatalyst solution. In addition, 60 weights of ethyl acetate, 10 weights of toluene, 20 weights of ethanol and 10 weights of 2-butanol are mixed, and 5 weights of photocatalyst solution is added to this mixed solution, and the photocatalyst coating is obtained after mixing. A-1.

manufacture example 2

[0040] Manufacturing example 2 (manufacturing of photocatalyst paint)

[0041] 60 wt. of ethyl acetate, 10 wt. of toluene, 10 wt. of isopropanol, and 20 wt. of tert-butanol were mixed. To this mixture, 1 weight of acetylacetone and 5 weights of organic anatase sol were added and mixed to obtain photocatalyst coating A-2.

manufacture example 3

[0042] Manufacturing example 3 (manufacturing of photocatalyst paint)

[0043] 60 wt. of n-propyl acetate, 10 wt. of isopropanol, 10 wt. of acetone and 20 wt. of 2-ethoxyethanol were mixed. Add 1 weight of acetylacetone and 10 weights of organic anatase sol to this mixed solution, and mix to obtain photocatalyst coating A-3.

Abstract

The present invention provides a method for stably fixing photocatalyst with emerged state on the organic polysiloxane membrane surface and its used coating composition. Said coating composition is a photocatalyst dispersion solution containing organic solvent, and said organic solvent can soften it by expanding and moistening organic polysiloxane, essentially, it contains no adhesive component. Said coating composition is applied on the organic polysiloxane membrane surface layer to make the organic polysiloxane membrane soften, at the same time the photocatalyst is attached on it, after the membrane is dried, the photocatalyst can be stably fixed on the membrane surface in emerged state mode.

Description

technical field [0001] The present invention is a method for immobilizing a photocatalyst on the surface of an object for the purpose of deodorization, air purification, surface hydrophilization, antifouling, etc. A method for immobilizing photocatalysts on organopolysiloxane coatings. The present invention also includes coating compositions for immobilizing photocatalysts. Background technique [0002] Due to the presence of oxygen and water, photocatalysts represented by titanium oxide generate active oxygen under the irradiation of near-ultraviolet light to oxidize substances. Using this phenomenon, photocatalysts can remove odorous substances and pollutants in the air, and make the surface of the substance antifouling, self-cleaning, antibacterial, etc. [0003] Because the photocatalyst is generally a powder, in order to achieve the purpose of use, it must be fixed with a solid substrate or a binder. Because photocatalysts, especially t...
