Abstract
A nano-class coated membrane for cleaning air and generating negative ions carries the TiO2 nanoparticles for generating electrons and holes in photocatalytic condition to trigger redox reaction which can decompose the harmful gas (formaldehyde) into CO2 and H2O and the polar ore nanoparticles for generating electric current under thermal excitation of pressure and temp to electrolyze the H2O and release negative ions.
Description
Technical field: the fabricating technology prescription that the present invention relates to a kind of " nano-anion coated film for air purification ".Belong to Nano/micron composite environmental-friendly function new material.
Technical background:
1, nano-TiO
2Photocatalysis research has formed a focus, but aspect air cleaning improvement, all follows the single purification function of Japan's " photocatalyst "; Though and anion generator has gone on the market but the consumed power source, effect has limitation.Estimate room air: pure air and lack anion and lack nutrition just as human body; The anion height is also nonsensical in the contaminated air.Have only clean air+high-concentration anion the most useful to human body.This research is started with from difunctional, high efficiency, performance air cleaning and the also cooperation usefulness of bringing out two kinds of materials of anion.Integrate, complement each other, mutually promote.In the air cleaning process, Xi Fu pernicious gas molecular oxidation-be reduced into carbon dioxide and water the most at last.This water further with polar mineral anion material generation exoelectrical reaction, promote anion to produce.Two-way " oxidation " and " electrolysis " circular response.Not only purify air but also induce anion.Build indoor high-quality air ambient, reach the park level.This is to solve science of small environment pollution and complete scheme.
2, anion has obtained the medical circle approval to the body-care effect.It is current because the urban development process is fast, the community resident concentrates high buildings and large mansions, house fitting.Air-conditioning is popularized+sealing, and indoor negative ion concentration is relatively low.Show according to relevant mensuration: anion has only 40-50/cm in the air-conditioning closed chamber
3(negative ion concentration is 400-1000/cm in the park
3).Improving negative ion concentration is a problem that can not be ignored.
Summary of the invention:
1, with nano-photocatalyst material (nano-TiO
2, ZnO
2, AgO etc.) wherein two kinds activate with rare earth oxide and to carry out complex group and dress up material for air purification.This material produces electronics (e under sunlight or light (ultraviolet ray) irradiation
-) hole (h
+) right, have strong OR function.In preparation process, do activation, compound, assembling, effectively solve nano particle and reunite, strengthen function.Thereby adsorption and oxidation decomposes in the air various pernicious gases and destroys bacterial cell membrane and solidify virus protein, further is oxidized to carbon dioxide and water, reach purify air, antibiotic, deodorizing purpose.Safe and reliable, non-secondary pollution.
2, thermal voltage Mineral with Polar Electricity tourmaline is prepared particulate and do to activate processing, enhancing function, formation anion material, this material surface electric field emission wavelength at normal temperatures are the infrared ray of 4-16 micron, in the motion process of contact atmospheric water molecule, electrolytic effect takes place, and induces a large amount of negative aeroions naturally lastingly.
3, air cleaning and anion material are assembled into iceberg solid solution, overcome precipitation and reunion.Filming, to present difunctional be innovative point of this product.
4, rationally selecting auxiliary material for use is important feature of this preparation of product.Be bonded to membrane material, select pure-acrylic emulsion or water soluble resin for use, immobilized nano particle; The reunion that dispersant selects for use Ludox effectively to solve nano particle makes it to be uniformly dispersed; Surfactant selects for use OP-O1 third=alcohol to gather the modification of methyl first diluted acid sodium, makes it to form hydrophilic emulsion.The spraying application air drying solidifies.Form transparent microfilm, this films and combines firmly with body surface, do not influence original color.
5, functional verification: can determine negative ion concentration content in the air with the negative ion concentration analyzer, measure the pernicious gas index with the formaldehyde determination instrument.This functional coating film: pernicious gas degradation rates 97% such as 48h formaldehyde; Negative ion concentration can reach 400-1000/cm
