Description
Technical field
The present invention relates to a kind of coating and preparation method thereof, be specifically related to a kind of clean taste anti-formaldehyde environment protection interior wall latex coating and preparation method thereof.
Background technology
Along with the raising of expanding economy and living standards of the people, multiple building and ornament materials have entered family and office space, VOC(volatile organic compounds) become the important substance polluting indoor air environment.And in VOC, formaldehyde is modal pollutent, it discharges mainly through the wood adhesive that uses in interior decoration, finishing material, furniture and plastic degradation, causes grave danger, become the number one killer of human health to HUMAN HEALTH.How to remove the formaldehyde in room air and other volatile organic matter, become the focus that people pay close attention to.
Internal wall emulsion coating because of its multicolour, low stain, toxicological harmless and be convenient to the distinguishing features such as renewal body of wall finishing in be used widely, if internal wall emulsion coating has the function of the obnoxious flavour such as decomposing formaldehyde, toluene, then can purify indoor air, improve living environment.
Current wall paint removes the method that formaldehyde mainly adopts physical adsorption or decomposition.Physical adsorption in coating, adds sorptive filler as gac, bamboo charcoal, diatomite, medical stone etc., reached the object removing formaldehyde by the adsorption of such filler.But the greatest problem of physical adsorption, exists saturation ratio exactly, saturated rear formaldehyde just can not be absorbed again, and changes when condition, and as when the temperature increases, the formaldehyde of absorption can be discharged in air again, causes secondary pollution; Decomposition carrys out decomposing formaldehyde by adding dioxide photocatalyst titanium, photocatalyst can form hydroxyl free radical and the ultra-oxygen anion free radical of strong oxidizing property after absorbing luminous energy on surface, objectionable impurities free in air and microbial decomposition are become harmless carbonic acid gas and water, thus reach purify air, sterilization, the object such as deodorizing, there is the features such as efficient, non-secondary pollution.Because titanium dioxide only absorbs UV-light, to visible light-responded low, and due to the compound of photo-generate electron-hole, cause photo-quantum efficiency very low, seriously constrain it and promote the use of on a large scale.
Summary of the invention
The object of the present invention is to provide a kind of clean taste anti-formaldehyde environment protection interior wall latex coating and preparation method thereof, its use can reduce the infringement of the objectionable impuritiess such as formaldehyde to human body and environment, anti-formaldehyde function and wash-resistant property good, photo-quantum efficiency is high, and can avoid producing mould etc., saving resource.
For achieving the above object, the present invention adopts following technical scheme:
A kind of clean taste anti-formaldehyde environment protection interior wall latex coating, its component and content (by weight percentage meter) as follows: visible light induced nano photocatalyst of titanium dioxide slurry 1% ~ 15%, only taste emulsion 15% ~ 35%, formaldehyde absorbent 1% ~ 15%, dispersion agent 0.5% ~ 2%, thickening material 0.2% ~ 3%, wetting agent 0.2% ~ 1%, defoamer 0.1% ~ 1%, film coalescence aid 0.5% ~ 5%, antifreezing agent 0.2% ~ 3%, color stuffing 20% ~ 40%, pH value regulator 0.1% ~ 1%, anticorrosion and bactericidal agent 0.01% ~ 0.1%, deionized water 15% ~ 40%.
Component and the content (by weight percentage meter) of described visible light induced nano photocatalyst of titanium dioxide slurry are as follows: 10%-60% visible light induced nano photocatalyst of titanium dioxide, 0.2% ~ 3% thickening material, 0.1% ~ 2% dispersion agent, 0.2% ~ 2% wetting agent, 5% ~ 25% clean taste emulsion, 0.1% ~ 0.5% defoamer, 30% ~ 80% deionized water.
Described visible light induced nano photocatalyst of titanium dioxide particle diameter is 10 ~ 100nm.
The mixture that described visible light induced nano photocatalyst of titanium dioxide is N doping nanometer anatase titania, sulfur doping nanometer anatase titania, phosphorus doping nanometer anatase titania, fluorine modify any one or any two or more in nanometer anatase titania, during any two above mixture, its proportioning is any proportioning.
Described clean taste emulsion is the mixture of any one or any two or more in clean taste pure-acrylic emulsion, benzene emulsion, organosilicon crylic acid latex, EVA emulsion, and during any two above mixture, its proportioning is any proportioning.
Described formaldehyde absorbent is the mixture of any one or any two or more in white bamboo charcoal, gac, natural mineral zeolite, diatomite, attapulgite, medical stone, and during any two above mixture, its proportioning is any proportioning.
Described color stuffing is the mixture of any one or any two or more in Rutile type Titanium Dioxide, zinc sulfide white, water-ground limestone, light calcium carbonate, talcum powder, calcined kaolin, mica powder, wollastonite powder, superfine alumina silicate, ground barium sulfate, silica powder, asbestos powder, White Carbon black, and during any two above mixture, its proportioning is any proportioning.
Dispersion agent, thickening material, wetting agent, flow agent, film coalescence aid, frostproofer, defoamer, pH adjusting agent, dispersion agent, thickening material, wetting agent, defoamer, film coalescence aid, antifreezing agent, pH value regulator, anticorrosion and bactericidal agent are auxiliary agent conventional in emulsion paint.
A preparation method for clean taste anti-formaldehyde environment protection interior wall latex coating, comprises the steps:
The preparation of A, visible light induced nano photocatalyst of titanium dioxide slurry
Take each component of visible light induced nano photocatalyst of titanium dioxide slurry in proportion, under the rotating speed of 300 ~ 600 revs/min, add deionized water, dispersion agent, thickening material, wetting agent, defoamer successively, after mixing, add visible light induced nano photocatalyst of titanium dioxide, under the rotating speed of 1000 ~ 1300 revs/min, disperse 20 ~ 30 minutes; Under the rotating speed of 300 ~ 600 revs/min, add clean taste emulsion, obtain visible light induced nano photocatalyst of titanium dioxide slurry;
The preparation of B, clean taste anti-formaldehyde environment protection interior wall latex coating
