Description
Technical field
The present invention relates to a kind of light catalyzed coating, and in particular to the method for preparing degraded catalysis material.
Background technology
Modern industry continues to develop a large amount of discharges for being usually associated with sewage, and wherein organic pollution influence is the tightest
Weight, conventional organic pollution processing mode is physical absorption and microorganism decomposition, however, these methods input is high, slowly effect
And decomposing organic matter is not thorough.
Photocatalysis method can remove the thorough mineralising of Some Organic Pollutants, be the nothing of various organic pollutions and reproducibility
There is provided be considered as a kind of ring of great future for the removal of the poisonous and harmful substance of organic pollutants, particularly bio-refractory
Border pollution depth purification techniques.Therefore, photocatalysis is used as healthy and environmentally hazardous substance the reason of the harm human body that can degrade
Think technology and get most of the attention.At present, photocatalysis Decomposition organic pollution technology is ripe day by day, i.e., under illumination condition, pass through light
The catalytic action decomposing organic pollutant of catalyst particularly titanium dioxide, this method cost is low, instant effect and decompose it is organic
Pollutant thoroughly, can degradable organic pollutant be low toxicity or nontoxic small molecule, reach the purpose of harmless treatment, so into
For a kind of new pollution processing mode, method the more commonly used at present is that titanium dioxide is prepared into light catalyzed coating to be coated in gold
Belong to matrix surface, the metallic matrix for being then coated with light catalyzed coating is put into sewage, however, titanium dioxide compares surface in itself
Product is big, surface can be big, easily reunite, can also be along with there is phenomenon that photochemical catalyst comes off so as to lose photocatalysis effect, together
When in the prior art titanium dioxide usually require that under ultraviolet light just there is higher photocatalytic activity, solar energy master
400-700 nanometers of visible-range is concentrated on, and the ratio that ultraviolet light is accounted in sunshine is only about 4%, therefore, existing skill
Utilization rate of the titanium dioxide in use to sunshine is relatively low in art, particularly in visible-range and without catalysis
Activity.
The content of the invention
Optically catalytic TiO 2 coating is easy to fall off in the prior art for the technical problems to be solved by the invention, while generally needing
Just there is higher photocatalytic activity under ultraviolet light, solar energy is concentrated mainly on 400-700 nanometers visible
Optical range, and the ratio that ultraviolet light is accounted in sunshine is only about 4%, therefore, titanium dioxide is in use in the prior art
Utilization rate to sunshine is relatively low, particularly in visible-range and without catalytic activity, it is therefore intended that provide for making
Make preparation for dropping the method for solution catalysis material, with the addition of Ludox and adhesive for building, not only increase the attachment of catalysis material with it is viscous
Attached ability, while the photocatalysis efficiency of titanium dioxide can be significantly improved, solves titanium dioxide and lacks present in photocatalysis
Point, and also there is the function of sterilization, make coating that there is organic pollution in the antibiotic and sterilizing and degraded air of efficient pollution-free
Function.
The present invention is achieved through the following technical solutions：
Method for preparing degraded catalysis material, comprises the following steps：1) titanium foil is taken, is made using anodizing
Titanic oxide nano tube thin-film, is dried；2) titanic oxide nano tube thin-film is added to progress hydro-thermal reaction system in zinc acetate solution
Zn titania nanotubes must be carried；3) Ludox, adhesive for building, water are mixed in proportion；4) by epoxy resin, bi-component
Polyurethane, acrylic resin, silicate, attapulgite modified, calcined kaolin, talcum powder, silane coupler KH-5, hydrogenation castor
Sesame oil, organic solvent are mixed evenly；5) by step 3) and 4) in solution mix, and add step 2) in load Zn titanium dioxides

The preparation method of the catalysis material of the present invention, with the addition of Ludox and adhesive for building, not only increases photocatalysis
The attachment of material and adhesive capacity, while the photocatalysis efficiency of titanium dioxide can be significantly improved, solve titanium dioxide in light
Shortcoming present in catalysis, and also there is the function of sterilization, make coating have the antibiotic and sterilizing of efficient pollution-free and degraded empty
The function of organic pollution in gas.Adhesive for building can be removed in high temperature so that photochemical catalyst is exposed outside, directly with air
Pollutant contact, the catalytic activity of photochemical catalyst is given full play to, while avoiding because photocatalyst for degrading drops organic adhesive
Agent and the catalyst obscission occurred；Ludox dehydration forms micro-pore in heat treatment process, can promote photochemical catalyst
Absorption to pollutant, and then strengthen photocatalysis performance.
The silicate is derived from any one in sodium metasilicate, potassium silicate, lithium metasilicate, calcium silicates, magnesium silicate or alumina silicate
