Description
Technical field
The present invention relates to a kind of high-efficiency deodorant.
Background technology
Ammonia, nicotine, suspended particulates, PM2.5, polonium -210 in domestic environment etc. be endanger most extensively, it is most tight
The room air pollution of weight, is the great cause of death in the whole world；The formaldehyde peculiar smell that house fitting-up is brought into, has stimulation, sensitization, causes to dash forward
The negative effects such as change, greatly endanger people's health；Musty, kitchen peculiar smell in environment（Oil smoke, acid smell etc.）, lavatory it is different
Taste etc. then greatly influences household quality, wherein the bacterial spore carried, become sour oil, methyl mercaptan, methyl amine, NH3 etc. are to people
The harm such as cause to cause a disease, be carcinogenic.
Pass through in the prior art frequently with plant absorption method, for example with the tropical water such as the plant such as sansevieria trifasciata prain, bracketplant, pineapple
Fruit, tealeaves or pomelo peel etc. realize the removal of peculiar smell, have absorption and fragrant the features such as covering concurrently, cheap effective, but remove speed
More slowly, emerging photocatalysis method is more is issued to the effect to eliminate the unusual smell with excitation of the photocatalyst material in light, general right
Partial organic substances and bacterium have certain removal and an insect killing effect, but the bad limited by practical of effect.
The content of the invention
In order to solve the above technical problem, the present invention provides a kind of high-efficiency deodorant, the macromolecule eliminating smell agent is by 100
The aqueous polyurethane of parts by weight, the polyacrylamide of 10-25 parts by weight, the nano zine oxide of 15-80 parts by weight, 0.03-0.3 weights
Measure the hydrogen peroxide of part and the modified Nano tantalum oxide of 3-10 parts by weight is prepared, the solid content of the aqueous polyurethane is
5-15%。
The macromolecule eliminating smell agent is prepared by following steps：
The aqueous polyurethane of 100 parts by weight, the nano zine oxide of 15-80 parts by weight and zirconia ball are added into container,
Filtering removes zirconia ball after when the stirring of 2000-5000 rotating speeds keeps 1-3 small, adds the hydrogen peroxide of 0.03-0.3 parts by weight,
When stirring 1-3 is small under 500-1200 rotating speeds；
Add 3-10 parts by weight nano oxidized tantalum, under 500-1200 rotating speeds stir 1-3 it is small when after, add 10-25 parts by weight
Polyacrylamide stir evenly, obtain macromolecule eliminating smell agent.
The average grain diameter of the nano zine oxide is 5-500 nanometers.
The particle diameter of the zirconia ball is 400-800 microns.
The modified Nano tantalum oxide is prepared by following steps：
At room temperature, the tantalic chloride of 3-10 parts by weight is dissolved in 100 parts by weight absolute ethyl alcohols, it is molten obtains tantalic chloride ethanol
Liquid, stands 5-30 minutes；
By the pucherite of 5-15 parts by weight, the blocked isocyanate of 0.01-0.1 parts by weight is added to tantalic chloride ethanol solution,
Close uniformly, obtain the first mixed liquor；
The first mixed liquor is kept stirring, 100 parts by weight of ethanol aqueous solutions are instilled into the first mixed liquor with the speed of 3-10ml/min
In；
N,N-Dimethylformamide is added, the first mixed liquor is kept stirring 30 minutes, is stored at room temperature to obtain the second mixed liquor；
After when the second mixed liquor and the 6-24 that is soaked in water under 30-45 degrees Celsius small, 40-45 degrees Celsius of dry 12-48 is warming up to
After hour, blocked isocyanate envelope temperature is warming up to and when keeping 3-10 small, be warming up to 100-160 degrees Celsius of drying to constant weight,
Dried object is obtained, the deblocking temperature of the blocked isocyanate is more than 50 degrees Celsius, less than 100 degrees Celsius；
By dried object in Muffle furnace, in 400-500 temperature lower calcinations, nano modification tantalum oxide is obtained.
The blocked isocyanate closes HDI for sodium hydrogensulfite.
The aqueous polyurethane of the present invention can effectively in sorbing material surface and air organic matter peculiar smell, nano oxygen
Change zinc to be uniformly distributed in aqueous polyurethane, the peculiar smell of absorption can be decomposed by nano oxidized tantalum soon, so as to realize
The a variety of odorous organic compounds of efficient degradation.By the mechanico-chemical reaction of shattering process, the decomposition for substantially increasing composition is organic
The ability of thing.The present invention uses sodium hydrogensulfite blocked isocyanate and pucherite to be prepared into as doping vario-property compound
The long-acting enzyme of spectrum arrived has the efficient ability of the decomposing organic matter under dim light.
Embodiment
