Abstract
A carrier containing nano-class TiO2 film as photocatalyst is prepared through preparing nano-class TiO2 sole, immersing refractory carrier in it several times or high-pressure injecting method, and heat treating at 500-600 deg.C to form nano-class TiO2 films in the arteries of carrier. Said carrier can be used in air conditioner for killing bacteria and sterilizing and refreshing air.
Description
Technical field
The present invention relates to nano-TiO
2The application of photocatalyst (photocatalyst) specifically is to contain nano-TiO
2The high-temperature resistant carrier of film and the application of this carrier on air-conditioning.
Background technology
Along with industrial expansion, environmental problem has become the major issue that countries in the world must face.Nano-TiO
2Run into germ, virus and formaldehyde, toluene, benzene, NO
2, toxic gas such as CO, can be their oxidation Decomposition CO just
2, H
2Therefore O can eliminate the pollution in newly-decorated house, fresh air, and do not contain organic antiseptic, eliminate environmental pollution.
Summary of the invention
The purpose of this invention is to provide nano-TiO
2The high-temperature resistant carrier that colloidal sol soaked, and this carrier is installed on the purpose that realizes sterilization, fresh air on the air-conditioning.
Technical scheme of the present invention is: titanate esters is dissolved in the absolute ethyl alcohol, adds chelating agent, stirring makes and mixes under the room temperature, adds ethanol water (volume ratio of water and ethanol 1: 9), drying retarder again, obtains nano-TiO
2Colloidal sol.
The consumption of above-mentioned chelating agent accounts for the 0.1-1% of colloidal sol gross weight, and the consumption of drying retarder accounts for the 1-2% of colloidal sol gross weight;
In order to improve photocatalytic activity, make in above-mentioned reaction, also can add ferric nitrate by the spectral red shift that absorbs, make the optical wavelength that absorbs move to 400nm by 388nm.
The preferred butyl titanate of above-mentioned titanate esters.
The nano-TiO that uses said method to make
2Colloidal sol adopts high pressure injection method or multiple maceration to soak high-temperature resistant carrier, through 500～600 ℃ of heat treatments, forms nano-TiO in the duct of carrier
2Film;
Above-mentioned high-temperature resistant carrier is porous ceramics or glass fibre or glass wool cloth;
Above-mentioned impregnation technology adopts high pressure injection method or multiple maceration, soaks into, soaks evenly;
The high pressure injection method: use lance ejection, nano TiO 2 colloidal sol enters the duct of porous ceramics under the effect of pressure; Multiple maceration: high-temperature resistant carrier is repeatedly immersed in the nano TiO 2 colloidal sol, make film reach certain thickness, sintering then.
The invention has the advantages that in the preparation process of colloidal sol not add any active material, do not have heavy metal ion and sodium, sulphion etc., do not have sewage discharge.Nano-TiO of the present invention
2Membrane carrier adopts porous ceramics or glass fabric, can stand 500～600 ℃ high temperature, and durable in use, specific area is big, the efficient height.
