Description
Technical field
The present invention relates to technical field of air purification, more particularly to a kind of purification of air weaving filter cloth and preparation method.
Background technology
With the requirement more and more higher of the industry factory building cleanliness factor such as medicine, health care, electronics, air cleaning unit is carried
Higher requirement is gone out.Dust, bacterium, virus and the microorganism floated in air must be removed by the way of appropriate.
Vapour interior space is relatively narrow and small, and plastic structural part, decorative articles meeting release formaldehyde, organic solvent, fuel system can discharge hydrocarbon
Type organic and carbon monoxide, the higher pollution of formation concentration in motor space, and human body and in-car bacterium, then it can release
Release the pollution that the smell pollution things, in-car smoke, peculiar smell etc. such as Ammonia, thio-alcohol, organic acid, indoles also increase in-car
Degree.Currently there are various in-car air clearing products, such as all kinds of air purifiers, purification of air charcoal bag.Air purifier is
The clean-up effect reached, it is necessary to increase air quantity, this causes its volume to increase, and limited in-car lay is brought in space
Inconvenience, and noise can also increase, and also often price is higher for in-car air purifier, and filter core also needs frequently to change.And air
Charcoal bag is purified, because it is passive adsorption effect, only when in-car air flow to its surface, pollutant is possible to be inhaled
It is attached, but because its surface area is too small, too small with in-car air contact area, often effect is also very limited.In many purification of air skills
In art, most widely used, most ripe is exactly air cleaner.American researcher was carrying out IAQ research in recent years
During find, air cleaner (is not arrived in use for some time and scraps the time limit) if deposition microorganism on the filter
It is acted upon not in time, serious secondary pollution will be produced.
Prevent air cleaner to be contaminated at present, be essentially all using ancillary method.Such as the sterilizing measure of air-conditioning system
Add smell photocatalysis purifier, but some problems brought simultaneously：Such as 1. cost increase of air-conditioner filtering system；2. needed during installation
There are enough spaces；3. necessary specification of the Aided design of whole system etc..So the selection of degerming method is quite important.With regard to mesh
Before for, using antimicrobial filtering material can yet be regarded as wisdom selection.In recent years, people start to carry out antibacterial air filting material
Concern and research.Chinese patent CN1475613A discloses nano-antibacterial nonwoven cloth filter and preparation method thereof, and the invention relates to
A kind of and nano-antibacterial nonwoven cloth filter and preparation method thereof.It is to resist 91-99 parts polypropylene fibre and 1-9 part silver system nanometer
Bacterium powder body, which is placed in agitator, is sufficiently stirred mixing, and the base-material of antibacterial filter material is made；The base-material of filter material is carried out by extruding machine
Consolute, molten state mixture is made；Molten state mixture is meltblown by melt-blown injection machine again, antibacterial nonwoven cloth filter is made
Material.Silver system antiseptic nano powder may be covered by macromolecule in the fabrication process in the product, so that antibacterial, fungistatic effect
Have a greatly reduced quality, in addition the product filter efficiency only 95%, it is impossible to the filtering material as high efficiency particle air filter.Chinese patent CN
2633397Y discloses a kind of Sterilizing and purifying air filter chip, and the inner core of chip is active carbon fiber felt-ACF felt multilayer knots
Structure, every layer of active carbon fiber felt surface are sprayed with non-chlorine type and chemically sterilize oxidant layer, be enclosed with active carbon fiber felt two sides
Nonwoven surface layer, there is nylon wire between active carbon fiber felt and nonwoven surface layer.It with the addition of in the product and chemically disappear
Toxic agent can bring the corrosion of air-conditioning system, and complicated, and production cost is higher.
Textile fabric as routine filtering material, mouth mask, air conditioner filter screen application in mainly filtering bulky grain thing.
If assigning the function of textile fabric catalytic decomposition organic toxic gas, textile fabric will be greatly lifted in environmental protection
Using.Textile fabric has good characterization of adsorption, the porous and capillary energy of fibrous material, makes fiber surface absorption rich
Collect pollutant, providing high concentration for nano-photocatalyst reacts substance environment.Therefore prior art is using photochemical catalyst as adding
Add and be applied to textile fabric, this largely accelerates photocatalytic degradation reaction rate.Such as poisonous formaldehyde is catalyzed
It is decomposed into such as carbon dioxide and water.With good air purification effect.It is to contaminate fiber to enter yet with photochemical catalyst
Row load, therefore, still has substantial amounts of toxic gas by textile fabric, therefore, purification efficiency is unsatisfactory.
