Abstract
The invention discloses interior wall paint capable of absorbing and decomposing formaldehyde. The interior wall paint is characterized by comprising the following active ingredients in percentage by weight: 30-45% of film forming base stock, 10-30% of filler, 1-4% of activated carbon powder, 3-5% of Na2SO3 doped modified bentonite, 3-8% of nanometer titanium dioxide, 2-5% of nanometer titanium phosphate, 11-20% of pigment and auxiliaries and the balance of water, wherein Na2SO3 accounts for 16-30% of the Na2SO3 doped modified bentonite.
Description
Technical field
The present invention relates to chemistry painting industry field, particularly relate to a kind of also interior wall coating of decomposing formaldehyde that absorbs.
Background technology
In the coating such as the woodenware in family room, plank, furniture, wall, all can contain formaldehyde, yet more frighteningly, the release period of formaldehyde is generally three to 15 years.No. 153 communique identification that the World Health Organization issued in 2004: formaldehyde is carcinogenic and causes deformed material.Formaldehyde is generally acknowledged allergen, is also one of potential strong mutagen, is also to 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, the function with 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 a plurality of patents of invention and technology report.As disclosed a kind of environment-friendly type photochemical catalysis interior wall coating in the Chinese Patent Application No. patent application that is 200310108889.7, it adopts inorganic, organic composite emulsion as filmogen, and photocatalyst is scattered in wherein with functional stuffing form, be aided with again auxiliary agent and other functional type additive, make a kind of Environmental Protective Water-paint of ambient cure; This coating is characterised in that to have following feed composition and weight percent proportioning: the mixed liquid 10-35% of one or both 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, be photocatalyst 2-15%, pigment and filler and other additive 10-20%, water solvent, surplus.
But this class coating of prior art only adds titanium dioxide optical catalyst, need to lean on photochemical catalysis, but unglazed or that light is faint is indoor, the effect of decomposing formaldehyde is undesirable.
Summary of the invention
For the deficiencies in the prior art, one of object of the present invention is to provide a kind of can absorb formaldehyde, and is having light and without interior wall coating that can effectively decomposing formaldehyde under optical condition.
For achieving the above object, the technical solution used in the present invention is: a kind of also interior wall coating of decomposing formaldehyde that absorbs, by weight percentage, described interior wall coating is by film forming base-material 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 that water forms, wherein Na
2sO
3in doping vario-property wilkinite, Na
2sO
3account for 16～20%.
Described film forming base-material 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 is to be selected from one or more in dispersion agent, flow agent, wetting agent, defoamer, sterilant, pH adjusting agent, matting agent and thickening material.
The formaldehyde interior wall coating beneficial effect of absorption of the present invention decomposing formaldehyde is:
1. Na of the present invention
2sO
3the Main Function of doping vario-property wilkinite and activity charcoal powder is in absorbed air, to obtain formaldehyde, by controlling Na
2sO
3accounting in wilkinite (16～20%), making it reach satisfied adsorption effect does not affect again the traditional performance of coating, meanwhile, has determined the content proportioning of itself and activity charcoal powder on the basis of great many of experiments, makes adsorption effect best.
2. can there is katalysis in nanometer titanium phosphate under unglazed and dark room conditions, and decomposing formaldehyde and other organic pollutant have deodorizing, degerming, mildew-resistant texts simultaneously, and effect is lasting.
3. nano titanium oxide is brought into play leading role PARA FORMALDEHYDE PRILLS(91,95) under the condition of light and is decomposed having.
4. based on 1. above-mentioned～3. point, the present invention has formed 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 defect saturated and that lost efficacy and put even again, and also overcome independent use nano titanium oxide and can not catch the defect that airborne formaldehyde and catalytic decomposition are subject to illumination condition restriction.
5. activity charcoal powder and Na
2sO
3the content of two kinds of sorbent materials of doping vario-property wilkinite has synergistic action effect, the total content of two kinds of components will affect the performances such as the brushing of coating and surface smoothness higher than 9%, and total content will not reach the effect of absorbing formaldehyde lower than 4%, and two kinds of sorbent materials content is not separately in the scope of above-mentioned restriction time, its adsorption effect will reduce greatly, lower than being used in conjunction with of 90%, two kind of above-mentioned content of sorbent material, the adsorption rate of formaldehyde in air is reached 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 effectively decomposing adsorbent formaldehyde lower than the two minimum; And if the content proportioning of the two is in above-mentioned scope separately time, will cause having light or without rate of decomposition under optical condition not etc., cause that to decompose effect bad; Therefore the cooperation of the two above-mentioned content reaches more than 99% the rate of decomposition of the formaldehyde after absorption.Applicant is on the basis of Theoretical Calculation and great many of experiments, determined the Optimum Contents of above-mentioned four kinds of effective constituents, the content cooperative effect of four kinds of components, the content of any component is not in above-mentioned scope, to cause adsorption effect variation, effective cooperation of above-mentioned four kinds of component concentrations adsorbs indoor formaldehyde and decomposes clearance to reach more than 97%, can long-acting and effectively reduce formaldehyde pollution, improves IAQ (indoor air quality).
