Description

A kind of balanced type MULTILAYER COMPOSITE filter material on air filter
Technical field
The present invention relates to air filters, more specifically to a kind of balanced type multilayer on air filter Compound filtering material.
Background technology
Environment is the space of human survival, including natural environment and daily life, study, working environment.With science and technology Development and living standards of the people raising, people are to many uncertainties for occurring in living environment with environmental problem to human body The influence of health is also increasingly paid close attention to.
Indoor pollution seriously affects health, is also referred to as the special disaster of modern city.Currently, in the world Room air pollution is classified as, maximum environmental factor is endangered to public health.Chinese environmental pollution has been over warning line, Empty gas and water, carbon dust, radiation and noxious material moment after contaminated encroach on our health, and the pollution of indoor environment is more tight Weight, building itself may also become the pollution sources of room air.
Air filter refers to solid contaminant in room air (such as dust, pollen, carry disease germs particle), gaseous contamination Object (finishing pollution etc. of peculiar smell, formaldehyde etc) has the household electrical appliance of certain removal ability.As people start to air matter The attention of gaseous contamination after amount and finishing, air filter start gradual fast sale on the market.
Instantly air purification mode is mainly passive type and two kinds active, active air filter mainly profit Purification factor is reached into each corner with diffused feature of air and carries out air purification, the place that air can permeate is Clean-up effect can be generated.But active purification is controversial technology in the world, because the pollutant in air is usually The even lower concentration of ten a ten thousandths, and active purification needs air filter to spray the chemicals of higher concentration into air The personal health safety of matter, this kind of no energy absolute guarantee user of clarifier is difficult then to make conclusion.
Passive type purification mainly uses adsorption cleaning pattern, and air purification is carried out using the pattern of wind turbine plus filter material.However, In existing air filter, filter medium structure as shown in Figure 1, on the surface of filter material 1 compound one layer of PTFE microporous barrier 2 again, from And cause the filter material filter efficiency for changing structure relatively low.
Invention content
In view of the above defects of the prior art, the object of the present invention is to provide a kind of on air filter Balanced type MULTILAYER COMPOSITE filter material, the dust that can effectively filter difficult capture, easily penetrate, to improve filter efficiency.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of balanced type MULTILAYER COMPOSITE filter material on air filter, including：By it is upper under pass sequentially through heat it is compound The up-protective layer of bonding, the first filter layer, adhesive linkage, the second filter layer and lower protective layer；
The up-protective layer, lower protective layer are the spun-bonded non-woven fabrics of PET or PE materials；
The adhesive linkage is the compound nonwoven cloth that PE is mixed with PET；
First filter layer, the second filter layer are PTFE microporous barriers.
The thickness of the up-protective layer, lower protective layer is 20g/ ㎡~50g/ ㎡.
The thickness of the adhesive linkage is 8g/ ㎡~20g/ ㎡.
In the above technical solution, a kind of balanced type MULTILAYER COMPOSITE on air filter provided by the present invention Filter material is formed using successively graded composite, and the porosity of unit area is made to greatly improve, and permeability is strong, realizes in-depth filtration, The depth of penetration of particle is polluted up to the 50%~99% of filter medium thickness, wherein there is the filter layer of 50% or more thickness to be used for Pollution particle is captured, contamination capacity and service life are substantially increased, particularly with mistake of the filter diameter between PM0.05~PM0.2 Efficiency is filtered up to 99.999999%.
Description of the drawings
Fig. 1 is the structural schematic diagram of existing Compound filtering material；
Fig. 2 is the structural schematic diagram of MULTILAYER COMPOSITE filter material of the present invention.
Specific implementation mode
The technical solution further illustrated the present invention with reference to the accompanying drawings and examples.
Shown in Fig. 2, a kind of balanced type MULTILAYER COMPOSITE filter material on air filter provided by the present invention, Including：By upper up-protective layer 3, the first filter layer 4, adhesive linkage 5,6 and of the second filter layer for passing sequentially through hot compound sticking under Lower protective layer 7.
Preferably, the up-protective layer 3, lower protective layer 7 are all made of the spun-bonded non-woven fabrics of PET or PE materials, the material Fusing point is between 180 DEG C~220 DEG C, main function：To play protection PTFE microporous barriers.
Preferably, the compound nonwoven cloth that the adhesive linkage 5 is mixed using PE with PET, the fusing point of the composite is at 130 DEG C Between~180 DEG C, main function：First, playing a supporting role, second is that playing the role of bonding, due to the fusing point of the composite material It is relatively low, in hot compound tense, first passes through adhesive linkage 5 and its PTFE microporous barrier upper and lower surfaces of is subjected to compound sticking, then, When hot combined temp is stepped up, PTFE microporous barriers carry out with corresponding up-protective layer 3, lower protective layer 7 compound viscous respectively again It connects.
Preferably, first filter layer 4, the second filter layer 6 are all made of PTFE microporous barriers.
Preferably, the thickness of the up-protective layer 3, lower protective layer 7 is 20g/ ㎡~50g/ ㎡.
Preferably, the thickness of the adhesive linkage 5 is 8g/ ㎡~20g/ ㎡.
In conclusion the dust filtration efficiency that the MULTILAYER COMPOSITE filter material of the present invention can improve difficult capture, easily penetrate, especially For filter efficiency of the filter diameter between PM0.05~PM0.2 up to 99.999999%, and there is wear-resistant, high temperature resistant and acid Alkali, not facile hydrolysis, service life are long, and cheap, with good economic efficiency and social benefit.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention, And be not used as limitation of the invention, as long as in the spirit of the present invention, the change to embodiment described above Change, modification will all be fallen within the scope of claims of the present invention.
