Description
Technical field
The present invention relates to Photocatalystic self-cleaning TiO 2 ceramic and preparation method thereof.
Background technology
Ceramic is widely used building and ornament materials, but owing to reason atmospheric pollutions such as industrial expansion, emission of automobile wastes cause the traditional ceramics goods in use, performance deposits all contaminations and deepening gradually, dirty and influence decorative effect gradually.Need the cost great amount of manpower and material resources to clean.
Summary of the invention
Problem to be solved by this invention provide a kind of not only can keep the fine and smooth bright and clean apparent characteristic of traditional ceramics but also can automated decontamination, the beautiful Photocatalystic self-cleaning TiO 2 ceramic and preparation method thereof that keeps clean lastingly.
Technical scheme provided by the invention is: Photocatalystic self-cleaning TiO 2 ceramic, comprise ceramic body or ceramic finished product, its key is: closely being compounded with on the ceramic body or on the glaze of ceramic finished product by nano titanium oxide is the photocatalysis thin film and the low temperature glaze of main component, the glaze formula of low temperature glaze is quartzy 25-30 part, Wingdale 4-5 part, borax 28-30 part, zinc oxide 8-10 part, zircon 5-8 part, more than be mass fraction, it with above-mentioned component mixing firing temperature 950-1000 ℃ low temperature frit glaze, with above-mentioned frit 92-96 part, kaolin 4-8 part, add 50-100 part water, the water-soluble organic polymer binder of 0-2 part (being mass fraction) mixes makes glaze slip, adopts existing glazing, firing process and equipment fire on the ceramic body or the glaze of ceramic finished product on.The gained glaze is smooth, fine and smooth, gentle, attractive in appearance, is beige, and is sub-translucent, acid and alkali-resistance, tension mill.
Above-mentioned photocatalysis thin film can be with low-carbon (LC) (C
1-4) alcohol is raw material as ethanol, butanols etc., metatitanic acid fat or strong acid oxygen titanium salt, water, by 100: 5-20: the mixed of 1.5 volume percent is made TiO 2 sol, and employing dip-coating or spraying method load to TiO 2 sol on the Ceramic glaze and obtain.
The present invention also provides the preparation method of above-mentioned Photocatalystic self-cleaning TiO 2 ceramic, with 25-30 part quartz, 4-5 part Wingdale, 28-30 part borax, 8-10 part zinc oxide, it is 950-1000 ℃ low temperature frit glaze that 5-8 part zircon (more than be mass fraction) mixes firing temperature, with above-mentioned frit 92-96 part, kaolin 4-8 part, add 50-100 part water, the agent of 0-2 part aforementioned adhesion mixes makes glaze slip, adopt existing glazing, firing process and equipment fire on the ceramic body or the glaze of Tao Cuihua porcelain finished product on, titanium dichloride load is compound to Ceramic glaze and adopts sol-gel technique, with metatitanic acid lipid as raw material under the acidity condition of pH=3-4, be added drop-wise to slowly hydrolysis in the ethanol, vigorous stirring prepares the titanium dioxide melten gel simultaneously, adopt dip-coating or spraying method that TiO 2 sol is loaded to Ceramic glaze, under 500-700 ℃ temperature calcination 1-3 hour, can obtain required Photocatalystic self-cleaning TiO 2 ceramic.
Above-mentioned low temperature glaze fire on the ceramic body or the glaze of ceramic finished product on, after ash is blown in cooling, carry out dip-coating or spraying TiO 2 sol immediately.To avoid Ceramic glaze to pollute TiO 2 sol is come off or pollute.This technology need not use distilled water, acetone equal solvent that Ceramic glaze is cleaned, and can simplify technology and reduce industrial cost.
The ceramic any surface finish exquisiteness attractive in appearance, gentle that the present invention is prepared is silvery white in color or the silver yellow look acid and alkali-resistance, anti-scratch mill.Under the irradiation of light, the various organism of the deposition surface of degrading have super hydrophilic simultaneously, and this specific character can make water soak into the surface better, is beneficial to the wash-out surface mass.Under normal conditions, the pollutent of ceramic surface is organism and inorganic dust granules mixture.The prepared ceramic of the present invention can be under illumination (as the sunlight incandescent light etc.), effective degraded organism wherein, and remaining inorganic dust thing is wind-force outside, and self gravitation comes off under the effects such as rain drop erosion power and the surface is kept clean lastingly.A large amount of uses are also capable of purifying air.Thereby by gained titanium dioxide self cleaning enamel of the present invention not only have the fine and smooth bright and clean apparent characteristic of traditional ceramics have again automated decontamination, lastingly keep clean attractive in appearance.
The present invention can be used for making wall, ornamental brick, sanitary china, ceramics such as household china are used for decorative constructure, communal facility, family room, lavatory, kitchen etc.
