Technical field
The present invention relates to air purification field, more particularly to a kind of air-conditioning air inlet filter screen with air filtration non-woven fabrics and
Its preparation method.
Background technology
Air-conditioning air inlet is typically provided with air inlet filter cloth, and on the one hand the effect of air inlet filter cloth is in preventing air
Granule foreign enter air-conditioning in, extend air-conditioning service life；On the other hand particulate in air can be adsorbed, plays purification empty
Gas is acted on.Requirement one generally to air-conditioning air inlet filter cloth is good filtration effect, can stop or adsorb most particle
Thing；Two is small windage, does not influence the air intake efficiency of air-conditioning as far as possible.
Air-conditioning air inlet filter cloth of the prior art, is generally only common non-woven fabrics, in order to ensure its air permeability, is subtracted
Small windage, generally has very big porosity, but so just have impact on its filter efficiency.If in order to improve filter efficiency again
Porosity certainly will be reduced, air intake efficiency can be influenceed again, so that cannot be satisfactory to both parties.
The Chinese patent of Application No. CN201610233859.6 discloses a kind of air filtration non-woven electret mistake

Electrostatic absorption principle is all make use of in above-mentioned two parts of patents, the tiny particles content in air can be effectively adsorbed, carried
Filter efficiency high.But some shortcomings are there is also, because above two filtering material is not for air-conditioning air inlet, in wind
It is less demanding in resistance, therefore their windage is higher, is not suitable for air-conditioning air inlet filter cloth.On the other hand, electret without
Spin in the preparation process of cloth, the adsorption efficiency after non-woven fabrics impregnates to PTFE emulsion is relatively low, the PTFE emulsion for being cannot for a long time, it is firm
Admittedly adsorbed by non-woven fabrics, so as to have impact on Electrostatic Absorption effect, particularly for a long time after electrostatic adsorption force decay it is serious.This
Outward, above-mentioned non-woven fabrics also lacks antibacterial functions.

Or four layers；The Electrostatic Absorption layer is air intake surface；Wherein, Electrostatic Absorption layer is the polyethylene nonwoven containing nanometer electret；
The antibiotic layer is the polyethylene nonwoven for being compounded with antibacterial material.
Air filtration non-woven fabrics of the invention is two-layer or four-layer structure, and wherein Electrostatic Absorption layer is air intake surface, wherein containing
There is a nanometer electret, electrostatic absorption principle can be utilized, it is higher in the porosity of non-woven fabrics, also can under the conditions of windage is less
The particulate matters such as the PM2.5 in air, pollen, dust, flue dust, dust mite are carried out effectively to filter, is adsorbed.Antibiotic layer is anti-to be compounded with
The polyethylene nonwoven of fungus matter, can play bactericidal action.
Non-woven fabrics of the invention can select two-layer or four layers of structure to be filtered according to the actual requirements.Wherein, 2 layers are
Replacement cycle is 15 days or so, and 4 layers of replacement cycle is 30 days or so.
Preferably, the windage of the windage more than the antibiotic layer of the Electrostatic Absorption layer.Due to air mistake of the invention
Filter non-woven fabrics requirement has relatively low windage, therefore under conditions of the Electrostatic Absorption low windage of layer is kept, in addition it is also necessary to reduce as far as possible
The windage of antibiotic layer.Due to the windage of the windage more than antibiotic layer of Electrostatic Absorption layer, even if therefore compound upper antibiotic layer has two
The windage of non-woven fabrics is not influenceed substantially after layer or four-layer structure, even if the non-woven fabrics of two-layer or four-layer structure, it is remained to
Enough keep low windage.
