Description
Technical field
The present invention relates to chemistry painting industry field, particularly relate to a kind of absorption and the interior wall coating of decomposing formaldehyde.
Background technology
All can contain formaldehyde in the coating such as the woodenware in family room, plank, furniture, wall, but more frighteningly, the release period of formaldehyde is generally three to ten five years.No. 153 publication identification that the World Health Organization issued in 2004: formaldehyde is carcinogenic and causes deformed material.Formaldehyde is generally acknowledged allergen, and being also one of potential strong mutagen, is also cause one of leukemic Hazard Factor of child.According to domestic medical journal and pertinent literature report, indoor formaldehyde can be summarized as hormesis, toxic action and carcinogenesis to the harm of HUMAN HEALTH.
Nano material can produce negative ion, have the function of decomposing formaldehyde, wherein nano titanium oxide effect is best, has been widely used in different field (comprising coating) for decomposing formaldehyde, improve Air quality, domestic existing multiple patent of invention and technology report.If Chinese Patent Application No. is disclose a kind of environment-friendly type photochemical catalysis interior wall coating in the patent application of 200310108889.7, it adopts inorganic, organic composite emulsion as filmogen, and photocatalyst is scattered in wherein with functional stuffing form, be aided with auxiliary agent and other functional type additive again, make a kind of Environmental Protective Water-paint of ambient cure; The feature of this coating is to have following feed composition and weight percent proportioning: one or both the mixed liquid 10-35% in organosilicon crylic acid latex and polyacrylate dispersion, silicon sol 5-15%, the mixed phase titanium dioxide granule of nano level Anatase or Anatase and Rutile Type, or surface treated titanium dioxide composite particle, i.e. photocatalyst 2-15%, pigment and filler and other additive 10-20%, water solvent, surplus.
But this kind of coating of prior art only adds titanium dioxide optical catalyst, need by photochemical catalysis, but in unglazed or that light is faint indoor, the effect of decomposing formaldehyde is undesirable.
Summary of the invention
For the deficiencies in the prior art, an object of the present invention is to provide one to absorb formaldehyde, and have under light and no light condition can the interior wall coating of effectively decomposing formaldehyde.
For achieving the above object, the technical solution used in the present invention is: a kind of interior wall coating absorbing also decomposing formaldehyde, by weight percentage, described interior wall coating is by film forming binder 30 ~ 45%, filler 10 ~ 30%, activity charcoal powder 1 ~ 4%, Na
2sO
3doping vario-property wilkinite 3 ~ 5%, nano titanium oxide 3 ~ 8%, nanometer titanium phosphate 2 ~ 5%, pigment and auxiliary agent 11 ~ 20%, surplus is water composition, wherein Na
2sO
3in doping vario-property wilkinite, Na
2sO
3account for 16 ~ 20%.
Described film forming binder is one or more in acrylic resin, organosilicon crylic acid latex and benzene emulsion.
Described filler is talcum powder, dicalcium powder or their mixture.
The particle diameter of described activity charcoal powder is not more than 100 microns.
The particle diameter of described nano titanium oxide is not more than 100 nanometers.
Described pigment is titanium dioxide, mica powder or their mixture.
Described auxiliary agent be selected from dispersion agent, flow agent, wetting agent, defoamer, sterilant, pH adjusting agent, matting agent and thickening material one or more.
Absorption of the present invention the formaldehyde interior wall coating beneficial effect of decomposing formaldehyde are:
1. Na of the present invention
2sO
3the Main Function of doping vario-property wilkinite and activity charcoal powder is obtain formaldehyde in absorbed air, by control Na
2sO
3accounting (16 ~ 20%) in wilkinite, makes the traditional performance that it not only reaches satisfied adsorption effect but also do not affect coating, meanwhile, the basis of great many of experiments determines the content proportioning of itself and activity charcoal powder, makes adsorption effect best.
2. can there is katalysis, decomposing formaldehyde and other organic pollutant in nanometer titanium phosphate under unglazed and dark room conditions, and have the effects such as deodorizing, degerming, mildew-resistant, effect is lasting simultaneously.
3. nano titanium oxide plays leading role PARA FORMALDEHYDE PRILLS(91,95) and decomposes under the condition having light.
4. based on 1. above-mentioned ~ 3. point, the present invention defines Na
2sO
3doping vario-property wilkinite and activity charcoal powder absorption, the circulation of being decomposed by nanometer titanium phosphate and nano titanium oxide is again combined, both overcome single adsorption mechanism in prior art and easily caused the saturated and defect of putting even again of losing efficacy, also overcome be used alone nano titanium oxide can not catch formaldehyde in air and catalytic decomposition by the defect of illumination condition restriction.
5. activity charcoal powder and Na
2sO
3the content of doping vario-property wilkinite two kinds of sorbent materials has synergistic action effect, the total content of two kinds of components will affect the performance such as brushing and surface smoothness of coating higher than 9%, and total content will not reach the effect of formaldehyde adsorption lower than 4%, and two kinds of sorbent materials content separately not in the scope of above-mentioned restriction time, its adsorption effect will reduce greatly, lower than 90%, two kinds of above-mentioned content of sorbent material with the use of making the adsorption rate of formaldehyde in air reach more than 98%; Equally, the content of nanometer titanium phosphate and nano titanium oxide is also that applicant determines on the basis of great many of experiments, and exceeding the two the highest limit will affect coating property, and total amount will cause can not effectively decomposing adsorbent formaldehyde lower than the two minimum; And if the content proportioning of the two not in above-mentioned respective scope time, will to cause having under light or no light condition rate of decomposition not etc., and cause discomposing effect bad; Therefore the cooperation of the two above-mentioned content makes the rate of decomposition of the formaldehyde after adsorbing reach more than 99%.Applicant is on the basis of Theoretical Calculation and great many of experiments, determine the Optimum Contents of above-mentioned four kinds of effective constituents, the content cooperative effect of four kinds of components, the content of any one component is not in above-mentioned scope, adsorption effect will be caused to be deteriorated, effective cooperation of above-mentioned four kinds of component concentrations makes indoor formaldehyde adsorb and decomposes clearance to reach more than 97%, long-acting and effectively can reduce formaldehyde pollution, improve IAQ (indoor air quality).
