Embodiment 1

[0063] 5% by weight of titanium isopropoxide [Junsei Chemical Co., Ltd.], 78.8% by weight of absolute ethanol, and 0.2% by weight of hydrochloric acid were mixed and stirred at room temperature at 1200 rpm for 20 minutes. Then, 10% by weight of titanium dioxide powder [Degussa P25, Germany] was added to the mixture.

[0064] 6% by weight of talc [DUKSAN PURECHEMICAL Co., Ltd.] was added to the resulting mixed solution, followed by treatment in an ultrasonic device [BRANSON Ultrasonic Co., DHA-1000] for more than 30 minutes to obtain a coating sol composition.

Embodiment 2

[0066] 5% by weight of titanium isopropoxide [Junsei Chemical Co., Ltd.], 78.5% by weight of absolute ethanol, and 0.2% by weight of hydrochloric acid were mixed and stirred at room temperature at 1200 rpm for 20 minutes. Then, 10% by weight of titanium dioxide powder [Degussa P25, Germany] was added to the mixture.

[0067] 6% by weight of talc [DUKSAN PURECHEMICAL Co., Ltd.] was added to the resulting mixed solution, and then treated in an ultrasonic device [BRANSON Ultrasonic Co., DHA-1000] for more than 30 minutes, and then 0.3% by weight was added to the resulting solution % copper acetate monohydrate [Junsei Chemical Co., Ltd., Japan] to obtain a coating sol composition.

Embodiment 3

[0069]The same procedure as in Example 1 was carried out except that instead of 6% by weight of talc, 5% by weight of diatomaceous earth [DUKSAN PURE CHEMICAL Co., Ltd.] was used.

Abstract

Disclosed is a photocatalytic coating sol composition and the method for preparing the same. The photocatalityc coating sol composition comprising 0.1% to 20% by weight of a photocatalyst, 0.1% to 10% by weight of an inorganic adsorbent, 1% to 20% by weight of an inorganic binder, 55% to 95% by weight of an organic solvent and if necessary 0.1% by weight to 10% by weight of a metal compound. Specifically, the present invention can remove harmful substances by coating photocatalytic coating sol composition prepared from photocatalyst, inorganic adsorbent, inorganic binder, metal compound and organic solvent on metal filter such as aluminum etc., and plastic filter such as polyethylene and polypropylene etc.used in environmental contaminants treatment system or air conditioning plant such as air-conditioner and air-cleaner, according to any one of and ordinary coating techniques such as spray method or dipping method etc. at room temperature.

Description

technical field [0001] The present invention relates to photocatalytic coating sol composition and preparation method thereof, more specifically, the present invention relates to the application of coating environment purification system with photocatalytic coating sol composition, and described coating method is, at room temperature, adopts such as Common coating techniques such as spraying or dipping, with the help of inorganic binders, on metal meshes such as stainless steel, non-ferrous metals such as aluminum, non-woven fabrics, ceramic filters and plastic filters such as polyethylene (PE) On the surface, a photocatalytic sol coating composition with high adsorption performance and high photocatalytic activity is applied. Background technique [0002] Previously, the traditional methods of dealing with environmental pollutants can be divided into two types. One is physical and chemical methods, including adsorption, condensation, solvent washing and catalytic oxidation...
