Background technology
Germany scientist Elst in 1889 and Ge Teer have found the existence of negative aeroion, have affirmed the biological meaning that negative aeroion exists to A Sha Maas in 1902 etc.The effect of negative aeroion is admitted by vast medical circle, except useful HUMAN HEALTH, also has sterilization, dedusting, deodorization.Generally speaking, the concentration of the space negative aeroion in the confined chamber of city is at 100/cm
3Below, 100~300/cm in street of greening
3, suburb, wilderness or 500~1000/cm in park
3, 10000/cm of health resort zone such as beach, forest and waterfall
3About.The reason that room air negative ion concentration level is low comprises factors such as number, natural ventilation, pollution.According to the theory that geodesy and atmosphere joint committee of geographical physics League of Nations adopt, negative aeroion is O
2 -(H
2O) or OH
-(H
2O)
nOr CO
4 -(H
2O)
nObviously, indoor air-anion concentration is low, is unfavorable for HUMAN HEALTH; That the concentration that improves the room air negative ion makes it to reach is outdoor, the level in suburb, wilderness or park is one of main purpose of the present invention.
Japanese environmentalist Kubo in 1986 finds that tourmalinite has anti-water pollution effect, and 1998 annual interests are declared the United States Patent (USP) of " method and apparatus that produces the air alkalion " with the brine electrolysis effect of tourmalinite.At present, mainly improve the concentration of room air negative ion, its main drawback with air negative ion generator: the one, consumes energy, the 2nd, when adopting corona discharge to produce negative aeroion, be easy to produce obnoxious flavour, as: oxynitride NO
xWith ozone O
3Deng.
Summary of the invention
The present invention is intended to contain the building coating that can in use constantly produce negative aeroion by providing, and solves the low problem of indoor negative ion concentration thereby utilize no energy consumption not have the technique means that obnoxious flavour supervenes.
The present invention is for overcoming the various shortcoming of above-mentioned air negative ion generator for this reason, and the transmitting anion function of developing the decorative material for internal wall that utilizes buildings increases the room air negative ion concentration and reaches outdoor wilderness level, and the utilization that does not have the consumption of the energy and other pollution is added rare-earth activated efficient generation negative aeroion tourmalinite composite superfine powder and dope for inner wall of architecture with efficient generation negative aeroion and the inner wall putty produced.
The shortcoming that the present invention overcomes the anion generator power consumption and pollutes utilizes employed putty of buildings interior decoration interior wall and coating to produce negative aeroion to increase negative ion concentration in the air.Main raw is the composition tourmaline powder body of rare-earth activated efficient generation negative aeroion in the generation negative aeroion coating, after it is mixed with various emulsions such as pure acrylic acid emulsion, various acrylic resin, vinylformic acid Synolac, organosilicon crylic acid latex, acrylate and vinyl acetate emulsion, benzene-acrylic emulsions, just formed and to have produced the negative aeroion dope for inner wall of architecture, and it is mixed in the putty paste commonly used, just can make and can produce the negative aeroion inner wall putty.
The interior wall coating prescription that can efficiently produce negative aeroion comprises:
Produce air negative ion material: rare-earth activated efficient generation negative aeroion tourmalinite composite superfine powder, account for 1%~30% of coating total amount, said rare-earth activated efficient generation negative aeroion tourmalinite composite superfine powder is to be mixed by tourmalinite rare earth composite salt or oxide compound and photocatalytic semiconductor material.
Base-material, i.e. filmogen: mainly comprise following several emulsion commonly used:
Wherein a kind of of various emulsions such as pure acrylic acid emulsion, various acrylic resin, vinylformic acid Synolac, organosilicon crylic acid latex, acrylate and vinyl acetate emulsion, benzene-acrylic emulsion, weight accounts for 10%~25% of coating total amount.
Filler: zinc sulfide white, superfine talcum powder, ultrafine heavy calcium, attapulgite, titanium dioxide, wollastonite powder, kaolin, wilkinite, nano zine oxide, nano titanium oxide etc. are wherein at least a, and weight accounts for 23%~50% of coating total amount.
Other auxiliary agent: totals such as dispersion agent, film coalescence aid, thickening material, defoamer, flow agent, sanitas, pH value conditioning agent, sanitas account for 1%~5% of coating total amount.
Water: account for 20%~30% of coating total amount.
Said superfine powder is meant that particle diameter below 10 microns, is preferably person below 5 microns among the present invention.
The nagative ion inner wall coating producing process describes in detail
1. prepare: with dispersion agent, thickening material and the suitable solution of other assistant concentration, base-material, filler and rare-earth activated efficient generation negative aeroion tourmalinite composite superfine powder take by weighing standby according to the ratio of prescription;
2. white slurry preparation: water, dispersion agent, auxiliary agent, part defoamer are modulated into solution in reactor, add the filler that is added successively, disperse fully to grind, cross vibratory screening apparatus, squeeze into stirred pot through sand mill at whipping process;
3. finished product preparation: the base-material of in stirred pot, packing into, pour at following white slurry of whipped state, stir, add flow agent, sanitas, defoamer, thickening material and an amount of pH value conditioning agent then;
4. discharging is packed.
Can produce negative aeroion inner wall putty prescription
Coating emulsion: a kind of 15~20% in the various emulsions such as pure acrylic acid emulsion, various acrylic resin, vinylformic acid Synolac, organosilicon crylic acid latex, acrylate and vinyl acetate emulsion, benzene-acrylic emulsion
Mierocrystalline cellulose 5~15%
In fine particle calcium carbonate and the coarse whiting at least a 30~40%
Talcum powder 10~20%
Water 10~20%
Anion material 5~10%
The explanation of negative ion putty production technique
1. white slurry preparation: take by weighing water 10~20%, put into stirred pot, add in fine particle calcium carbonate and the coarse whiting at least aly 30~40% in whipping process successively, talcum powder 10~20% stirs;
2. in white slurry whipping process, add anion material 5~10%, stir;
3. on basis 2., Mierocrystalline cellulose is added and be uniformly dispersed;
