Description
Technical field
The present invention relates to indoor or outdoors air purification field, more particularly to it is a kind of except the air purification automatically cleaning material of formaldehyde
Material and preparation method thereof.
Background technology
With the continuous enlarging of modern city, urban architecture living space gradually expands, and Environment-Ecosystem destroys increasingly
Crisis, and the growth for expanding necessarily promotion interior decoration industry of living space, and non-environmental protection plate in excessively fitting up and fitting up
The use of material causes the contaminants situation such as formaldehyde in air benzene, TVOC serious.
At present, domestic air treating product be concentrated mainly on administer indoor and outdoor finishing material bring formaldehyde, benzene,
Ammonia, TVOC（Total volatile organic compounds）Deng the room air pollution caused by pernicious gas, and these improvement products are most
Number is all to coordinate to outdoor air emitting formaldehyde to reach effective regulation effect, this be also cause in recent years urban air-quality it is straight
One of the main reason for line declines.For outside atmosphere pollution control, because space is not closed, pollution sources are more complicated, at present
The country be concentrated mainly on reduction discharge etc. the enterprising professional etiquette in source draw administer, it is single discharge source substantially disclosure satisfy that country for
The requirement of discharge, but numerous individuals are discharged into polluted gas total amount in air considerably beyond country and resident to air quality
Standard and requirement.
For having discharged into how the polluted gas in air is administered, there is presently no any comparison is effective and low
Cost and the improvement product easily promoted, only some passive-type labour protection articles for use have partial air purification function.
The content of the invention
In view of the above-mentioned state of the art, by continuous technical research, the making of this formula is completed.The present invention wants
The technical problem of solution be to provide it is a kind of can in clean room and outside atmosphere pollution except formaldehyde material for air purification and
Its preparation method.
Technical solution is used by the present invention solves above-mentioned technical problem：It is a kind of except the material for air purification of formaldehyde, by
Following percentage by weight raw material is made：
Solution diluent 5%-13%
Deionized water 45%-55%
TiO 2 sol 20%-26%
Negative ion powder 1%-3%
Surfactant 0.5%-1.5%
Dispersing aid 10%-16%
Omega-9 aliphatic acid 1.6%-2.5%
The sum of percentage of each component is 100%.
Further, the solution diluent is propane diols.
Further, the TiO 2 sol is ultra micro nano-titanium dioxide solvent.
Further, the dispersing aid is polysiloxane copolymer emulsion.
Further, the Omega-9 aliphatic acid is oleic acid.
A kind of preparation method of material for air purification except formaldehyde, includes the following steps：
A. each component is mixed to get mixed solution according to said ratio；
B. mixed solution a obtained, which is put into, can carry out material the strong crushing of high speed, disperse to make material mix rapidly, dissolve
Dispersion machine in obtain solvent；
C. being ground of obtaining of b step is obtained into the troubled liquor that is creamy white；
D. by the material for air purification of resulting solution after the solution natural filtration obtained by step c.
Further, the granular size for the material for air purification that the step grinding is obtained by filtration is 30-60 nanometers.
The present invention is according to photocatalysis principle, and under the catalysis of photon, light-catalyzed reaction occurs for negative ion powder and titanium dioxide,
Wherein, negative ion powder can be with formaldehyde, benzene, the TVOC of pollution air（Total volatile organic compounds）Addition occurs Deng pollutant
Reaction generates a kind of compound of stabilization and sinks on bottom surface, achievees the purpose that to remove formaldehyde in air；Meanwhile titanium dioxide occurs
Two opposite polarity high energy particles are produced during light-catalyzed reaction（Light induced electron and photohole）, this high energy particle and surrounding
Water, oxygen reaction generation with Strong oxdiative-reducing power hydroxyl radical free radical, the pollutants such as the formaldehyde in air, benzene is straight
It is in harmless tasteless material to connect decomposition, reaches except formaldehyde, purifies the effect of air.
Compared with prior art, the advantage of the invention is that：Material for air purification prepared by the present invention is in liquid, using mist
Change, spray in air to can reach and remove formaldehyde, benzene, TVOC in outside atmosphere（Total volatile organic compounds）It is dirty Deng air
Thing is contaminated, improves air quality；Meanwhile product of the present invention can independently adsorb air by being atomized, being sprayed on building outer wall
Middle PM2.5, free formaldehyde, particle dust thing, reach cleaning effect, present invention design is reasonable, accords with the demands of the market, is adapted to push away
Extensively.
