Abstract
The present invention discloses an anti-virus mask. Three layers of mesh screens are respectively arranged in a gauze sandwich layer, wherein a covering layer with nanometer active carbon and rare earth is arranged on a grid framework of an active carbon mesh screen (1); a covering layer with nanometer kaolin clay and the rare earth is arranged on a grid framework of a kaolin clay mesh screen (2); a covering layer with nanometer zeolite and the rare earth is arranged on a grid framework of a zeolite mesh screen (3); the mesh screens are folded and arranged, and the grid frameworks are made of a metal material, or a macromolecular material, or the hybrid material of the metal material and the macromolecular material; the shapes of the grids of each mesh screen are different, or the arranging method of the grids are different. The present invention can reduce the thickness of the mask, and improve an antiviral protection effect of the mask.
Description
Technical field
The present invention relates to a kind of antiviral protective mask.
Background technology
The protective mask that tradition is used is to be formed by stacking by ten multilayers even 20 multilayer gauzes, but it can only stop 60%-70% virus, and its protection effect is had a greatly reduced quality.If the raising protection effect must increase the gauze number of plies, its thickness is increased, cause and use inconvenience.If adopt non-woven fabrics gauze mask also can only stop 80% virus.
Summary of the invention
The invention provides a kind of highly efficient anti-virus protective mask that can block myxovirus.
Technical scheme of the present invention is: be respectively equipped with three layer filtration stamen sheet in the gauze interlayer, wherein the grid frame of active carbon filtration stamen sheet is provided with the clad of nano level active carbon and rare earth, the grid frame of kaolin filtration stamen sheet is provided with the clad of nano-kaoline and rare earth, the grid frame of zeolite filtration stamen sheet is provided with the clad of nanoscale zeolite and rare earth, each filters the superimposed arrangement of stamen sheet, and grid frame is metal material, macromolecular material or metal and macromolecule composite material.
Mouth mask of the present invention limit is provided with opening, and opening part is provided with slide fastener or sealing strip, respectively is provided with two-layer gauze before and after the filtration stamen sheet after the superimposed arrangement.Each lattice shape of filtering the stamen slice graticule is inequality, and perhaps the arrangement mode of grid is inequality, and the mesh spacing that ground floor filters the stamen sheet is 0.2mm, and the mesh spacing that the second layer filters the stamen sheet is 0.2mm, and the mesh spacing of three layer filtration stamen sheet is 0.2mm.
The preferred version of grid frame can adopt nonwoven in the present invention.Kaolin filters the stamen sheet and then is clipped between active carbon filtration stamen sheet and the zeolite filtration stamen sheet.
Because nano level active carbon, kaolin, zeolite and rare earth have extremely strong adhesiveness, therefore in a single day it is sprayed on the grid frame that filters the stamen sheet, form firm clad immediately.Nano material has high gas permeability in addition, the gas permeability not influence of the formation of clad to filtering the stamen slice graticule.Activated carbon is a kind ofly commonly used to draw attached dose, can not only adsorb solid, the pernicious gas in can also adsorbed gas.Kaolin is a kind of liquid to be had the material of strong adsorption capacity, because virus, bacterium is normal is bonded together with airborne hydrone, have water-based and then be easy to be adsorbed by it, but to solid dust, especially the dried dust suction-operated is not strong.Zeolite is a kind of material that all has strong adsorption capacity for solid, liquid, gas and plasma.In the present invention active carbon filtration stamen sheet be placed on front side, kaolin filter the stamen sheet be placed with in the middle of, zeolite filtration stamen sheet is placed on rear side, active carbon filtration stamen sheet can effectively block sticking part bacterium, virus, granule, kaolin filters the stamen sheet can effectively block myxovirus, and zeolite filtration stamen sheet then further blocks myxovirus and thinner particle.Each filters the superimposed arrangement of stamen sheet, each lattice shape of filtering the stamen slice graticule is inequality, perhaps the arrangement mode of grid is inequality, make difference filter the skeletons of the grid of stamen sheets corresponding to compartment, the adhesiveness of nano material can be blocked the virus that contains in the passing gas effectively in addition, every layer is effectively blocked sticking 80%--90%, three layers of virus of effectively blocking sticking 99.2%--99.9%.Nano-scale rare earth has the effect of kill virus, thereby the present invention can also effectively eliminate the virus in the passing gas.The mouth mask limit is provided with opening, installs simple and easy slide fastener or sealing strip, after being convenient to regular taking-up and respectively filtering the disinfection of stamen sheet, changes the gauze cover and comes into operation.Owing to use three layers to block sticking stamen sheet and four layers of gauze of filtering, thickness reduced, the convenient use.If the virus carrier then oppositely is with mouth mask, promptly active carbon filtration stamen lamella guarantees that near mouth and nose virus is free from environmental pollution.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the structure chart of mouth mask of the present invention
The specific embodiment
According to shown in Figure 1, the antiviral protective mask of the present invention, make the gauze cover, gauze cover front and rear part respectively is two-layer, middle for filtering stamen sheet chamber, top is provided with opening 4, and opening 4 places are equiped with simple and easy slide fastener, and it is parallel superimposed and be placed on and filter in the stamen sheet chamber that active carbon filtration stamen sheet 1, kaolin filter stamen sheet 2 and zeolite filtration stamen sheet 3.The skeleton that filters the stamen sheet is formed by the braiding of stainless steel silk thread, also can adopt nonwoven, and the grid lattice shape of the filtration stamen sheet in the middle of being placed on is square, and the lattice shape that is placed on the filtration stamen slice graticule of front side and rear side is the opposite parallelogram of direction.Spraying active carbon and rare earth is activated carbon filtration stamen sheet 1 on the grid that filters the stamen sheet, and spraying kaolin and rare earth is that kaolin filters stamen sheet 2 on the grid of filtration stamen sheet, and spraying zeolite and rare earth is zeolite filtration stamen sheet 1 on the grid that filters the stamen sheet.The mesh spacing of activated carbon filtration stamen sheet 1 is 0.2mm, and the mesh spacing that kaolin filters stamen sheet 2 is 0.2mm, and the mesh spacing of zeolite filtration stamen sheet 3 is 0.2mm.Activated carbon filtration stamen sheet 1 is placed on the front side, and in the middle of kaolin filtration stamen sheet was placed on, zeolite filtration stamen sheet 3 was placed on rear side.The weight ratio of nano-scale rare earth and another kind of nano material is 20%: 80%.Nano material adopts the preparation of calcining vapor method, and its granularity is the 50--500 nanometer, and during less than 1000 nanometers, nano material promptly has various nano-meter characteristics according to the report granularity.Two kinds of nano materials are mixed in advance, are painted on the grid then; Also can be earlier on grid coating adhesive spray mixed nano material then.Grid also can be macromolecular material die casting, also can be formed by the braiding of tinsel outer wrapping macromolecule.
