Abstract
A disclosed nanometer-level photocatalyst roll coating agent is characterized by comprising 0.1-2% of a photocatalyst containing nanometer TiO2, 25-29% of an alkyl sulfonate, 35-39% of organosilicon and the balance distilled water. The nanometer TiO2 catalyzer is subjected to concentrated solution alcoholization processing and ultrafine filtering, so that the particle size scope is 2-9 nm.
Description
Technical field
The present invention relates to a kind of nanometer light catalyst rolling coating agent, belong to photocatalyst technology field.
Background technology
?photocatalyst is a kind of nano level metal oxide materials (titanium dioxide is more conventional), and it coats substrate surface, under the effect of light, produces strong catalyzed degradation function: toxic and harmful in the air of effectively degrading; Can effectively kill various bacteria, and the toxin that bacterium or fungi can be discharged decomposes and harmless treatment; Also possesses the function such as deodorizing, anti-soil simultaneously.Photocatalyst is under the irradiation of light, can produce similar photosynthetic light-catalyzed reaction, produce oxidation capacity extremely strong free hydroxy and active oxygen, there is very strong photoredox function, the various organic compound of oxidable decomposition and part inorganics, can destroy the cytolemma of bacterium and solidify viral protein, can kill bacteria and decomposing organic pollutant, organic pollutant is resolved into free of contamination water (H
2o), carbonic acid gas (CO
2) and other innoxious substance, thereby there is extremely strong sterilization, deodorizing, mildew-resistant, anti-fouling and self-cleaning, air purification function.
People commonly use air freshener, activated carbon, deodovization agent etc. and solve indoor pollution, short and property for once of effective time of these products, and have problem of secondary pollution, and the appearance of photocatalyst is once epoch-making air cleaner revolution.Photocatalyst is a kind of nano level metal oxide materials (titanium dioxide is more conventional), and it coats substrate surface, and the dry rear film that forms, under the effect of light, produces strong catalyzed degradation function: toxic and harmful in the air of effectively degrading; Can effectively kill various bacteria, antibiotic rate is up to 99.99%, and the toxin that bacterium or fungi can be discharged decomposes and harmless treatment; Also possesses the function such as deodorizing, anti-soil simultaneously.Photocatalyst be beche-de-mer without spike with under the catalyzer that reacts.Under illumination, the surface of titanium dioxide forms electric cave and free electron, in conjunction with airborne water and oxygen, there is redox reaction, surface forms hydroxyl free radical (OH) and the ultra-oxygen anion free radical (02-) of strong oxidizing property, can decompose aerial obnoxious flavour and part mineral compound, and bacteria growing inhibiting and viral activity, reach sterilization, purifying air, deodorizing, mildew-resistant.Due to scientific and technological develop rapidly, nanotechnology is maked rapid progress, and scientist makes many materials after nano particle, finds that great variety has occurred for its original physics, chemical property, has produced many beyond thought effects.Nano titanium oxide is to start to use in the nineties, and it can produce light-catalyzed reaction endlessly in the situation that having light, produce a kind of can decomposing organic matter, suppress the material (hydroxyl free radical) of the functions such as virus activity but itself do not consume.Scientist by it be applied to antibacterial, purify air, deodorizing, sterilization, mildew-resistant, self-cleaning etc. and play good effect.How photocatalyst being applied to rolling coating agent is a problem demanding prompt solution.
Summary of the invention
The present invention is directed to the proposition of above problem, and develop a kind of nanometer light catalyst rolling coating agent.
The technical scheme that the present invention takes:
A kind of nanometer light catalyst rolling coating agent, is characterized in that: contain nanometer Ti0
