Abstract
The present invention provides a kind of universal mask, it includes mask main body and the ear-hang or headband that are symmetrically connected to the mask main body two sides, the mask main body has the rigid profile to fit like a glove with human face's feature, the mask main body is made of the first nonwoven layer, honeycomb catalyst metal layer, porous antibacterial absorption composite layer, nanoporous filtered polymeric layer and the second nonwoven layer from outside to inside, and the nanoporous filtered polymeric layer has the microstructure for nanoaperture of average pore size in the range of 30nm-45nm of wherein gathering.The universal mask has excellent PM2.5 filter efficiency, bacteriological filter performance and oil smoke removal rate simultaneously and comfortable wearing is beautiful.
Description
Technical field
The invention belongs to hygiene article sectors, and in particular to a kind of universal mask.
Background technique
Currently, environmental problem, especially air pollution, have become serious social concern, affect more and more
The normal life and health of people.For example, factory increases with industrial development, and people's burning fossil fuel, such as petroleum,
Coal etc., the pollutant being discharged into air is growing day by day, causes haze weather more and more.It is reported that haze is to cause the heart
The major reason of vascular diseases and respiratory tract system disease, 10 μ g/m of the every rising of Inhalable Particulate concentration3, breathing
Systemic disease rises 3.4%, and cardiovascular disease rises 1.4%, and daily general mortality rate rises 1%.In addition, the culinary art side of Chinese tradition
Formula can generate a large amount of oil smoke, these oil smoke contain various aldehyde, ketone, alcohol and its derivative and multiring aromatic hydrocarbon and heterocyclic amine
Equal toxic chemical substances, to seriously endanger the housewife of the long campaigns cooking and for a long time in the highly concentrated environment of kitchen fume
The health of the cook of lower work, especially the level-ones carcinogenic substance such as BaP, volatile nitrosamine, heterocyclic amine compound.In addition,
Germ in air is also always engraved in threat people's health.In order to protect people's health, have been developed that more and more
Gauze mask.However, the haze performance of existing mask is extremely limited at present, anti-microbial property is also insufficient, or for kitchen
Room oil smoke is helpless.In spite of mask there is certain haze performance, but it is not particularly suited in kitchen and doctor
The places such as institute using or the places such as kitchen and hospital using when can not have effect；Or in spite of mask have one
Fixed sterilization resistance energy, but its be not particularly suited for the open spaces such as kitchen and haze weather using or in kitchen and
The open spaces such as haze weather using when can not have effect.Therefore needing to develop one kind being capable of pre- haze, kitchen simultaneously
The universal mask of oil smoke and germ.In addition, the main body of existing haze mask is usually relatively soft, when wearing and non-fully
It is fitted on human face, especially at certain features such as bridge of the nose and lip of human face, causes to wear uncomfortable, be difficult to keep away
Exempt from air to leak in and wear unsightly.
Summary of the invention
There is excellent PM2.5 filter efficiency, bacteriological filter performance and oil smoke simultaneously the object of the present invention is to provide a kind of
The universal mask of removal rate and comfortable wearing beauty.
In order to achieve the above object, the present invention provides a kind of universal mask comprising mask main body and symmetrically connects
The ear-hang or headband in the mask main body two sides are connect, wherein the mask main body has the rigidity to fit like a glove with human face's feature
Profile, and the mask main body is compound by the first nonwoven layer, honeycomb catalyst metal layer, the absorption of porous antibacterial from outside to inside
Layer, nanoporous filtered polymeric layer and the second nonwoven layer are constituted, and the nanoporous filtered polymeric layer has wherein close
The microstructure of nanoaperture of cloth average pore size in the range of 30nm-45nm.Above-mentioned technical proposal according to the present invention, can
To provide excellent PM2.5 filter efficiency, bacteriological filter performance and oil smoke removal rate simultaneously, therefore mask of the invention can be same
The multiple functions such as Shi Shixian haze, lampblack-preventing and Anti-bacterium.In addition, universal mask according to the present invention can also mention simultaneously
High wearing comfort is prevented air leakage caused by being misfitted due to mask and face and promotes the aesthetic feeling worn.
Further, the porous antibacterial absorption composite layer is with range of the average pore size in 65nm-100nm of wherein gathering
The microstructure of interior nanoaperture.Above-mentioned technical proposal according to the present invention can provide superior PM2.5 filter efficiency
With bacteriological filter performance.
Further, the honeycomb catalyst metal layer has the wherein carried noble metal catalytic particles on catalytic metal foam
The microstructure of son.Above-mentioned technical proposal according to the present invention can provide especially excellent oil smoke removal rate.
Further, the universal mask further includes filling for adjusting the elastic adjusting of ear-hang or headband tightness
It sets.Above-mentioned technical proposal according to the present invention, can be further improved wearing comfort, avoid due to ear-hang or headband excessively pine or
Discomfort caused by tension.
Further, the porous antibacterial absorption composite layer includes 10-20 weight % active carbon, 35-45 weight % poly- season
Ammonium salt and 35-45 weight % film forming agent.Above-mentioned technical proposal according to the present invention, will be to peculiar smell, dust, the VOC etc. in air
Active carbon with strong adsorption capacity forms in the presence of film forming agent single with the polyquaternium with good antibacterial ability
Film simplifies Respirator structure so that the single film has the dual function of antibacterial and absorption.
Beneficial effect
According to the present invention it is possible to provide a kind of while there is excellent PM2.5 filter efficiency, bacteriological filter performance and oil smoke
The universal mask of removal rate and comfortable wearing beauty.The universal mask not only can be with haze, but also can be gone back with Anti-bacterium
