Description

A kind of mouth mask filter core for purifying PM2.5
Technical field
The utility model belongs to filtering material technical field, is specifically related to a kind of mouth mask filter core for purifying PM2.5.
Background technology
PM2.5 refers to that in air, diameter is less than or equal to the particle of 2.5 microns, also referred to as entering lung particle, its diameter is less than 1/20 of the hairline thickness of people, not easily stopped, directly bronchus can be entered after being inhaled into human body, the gas exchanges of interference lung, causes the disease comprising the aspects such as asthma, bronchitis and cardiovascular disease.PM2.5 also can become the carrier of virus and bacterium in addition, for the propagation of respiratory infectious disease is added fuel to the flames.Secondly, the micronic dust entering alveolar can be absorbed rapidly, directly enter blood circulation without liver detoxification is distributed to whole body, and pernicious gas wherein, heavy metal etc. dissolve in blood, larger to the injury of health.And wear mouth mask be prevent suck PM2.5 the most effectively, the simplest method.But market today especially carries out for this superfine particle the mouth mask that protects and few, the overwhelming majority uses non-woven fabrics, gauze, plastic net cloth etc. to be prepared from, they to knit hole or mesh all comparatively large, some tiny particles or flue dust can enter nasal cavity through mouth mask; In order to prevent air pollution, prevent Inhalable Particulate, organic matter, all kinds of dusty gas to the infringement of human body, need badly one effectively can filter PM2.5 simultaneously can sterilizing and low price, the simple mouth mask of use;
A kind of adsorbent be most widely used at adsorbing domain active carbon, but the general and regeneration difficulty of its absorption property.And Graphene has larger specific area, excellent mechanical strength, and very strong complex reaction between organic pollution, can be produced, thus have very strong adsorption capacity to organic pollution.Simultaneously the pollutant such as heavy metal ion, solid particle also has extremely strong suction-operated.As the preparation method that application number is the graphene composite material disclosing a kind of adsorbing polycyclic aromatic hydrocarbon pollutants in the Chinese patent of 201010579924.3, this graphene composite material of the results show has significant adsorption effect to polycyclic aromatic hydrocarbon pollutant.Application number is the preparation method disclosing a kind of graphene oxide antibacterial composite material in the Chinese patent of 201410306950.7, this composite has excellent surface Raman enhancement scattering effect, anti-microbial property, all has good inhibitory action to staphylococcus aureus and Escherichia coli.
Based on above shortcoming and defect, propose Graphene/activated carbon composite to be used for mouth mask filter core, can PM2.5, organic pollution, heavy metal contaminants etc. effectively in absorbed air, effectively can kill the bacterial virus of air simultaneously.
Summary of the invention
The object of the invention is to provide a kind of mouth mask filter core for purifying PM2.5, the technical scheme taked is: for purifying the mouth mask filter core of PM2.5, it is outer by polypropylene spunbond non-woven fabrics, polypropylene spunbond non-woven fabrics internal layer, polypropylene spunbond non-woven fabrics intermediate layer, Graphene/activation carbon composite layer forms layered laminate, described Graphene/activation carbon composite layer bag is placed on described polypropylene spunbond non-woven fabrics intermediate layer, in described Graphene/activation carbon composite layer, the thickness of Graphene is 0.7 ~ 100nm, diameter is 60 ~ 600000nm, specific area is 50 ~ 3000m 2/ g, described polypropylene spunbond non-woven fabrics is outer, form by PUR is bonding between Graphene/activation carbon composite layer and each layer of polypropylene spunbond non-woven fabrics internal layer.
Uniform by some air-vents respectively on described polypropylene spunbond non-woven fabrics skin, polypropylene spunbond non-woven fabrics internal layer and polypropylene spunbond non-woven fabrics intermediate layer, the aperture of described air-vent is 5 ~ 10um.
The beneficial effects of the utility model are: the mouth mask filter core for purifying PM2.5 of the present utility model, by multiple filtration and suction-operated, have effectively achieved and intercept the object that PM2.5 particle enters human body, and Graphene/activation carbon composite layer has potent absorption affinity, also have the effect of sterilizing concurrently simultaneously, can prevent the pollution of the environment and can to prevent the spread of disease again to the infringement of human body, be worth producing and promoting.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation, in figure:
1. polypropylene spunbond non-woven fabrics is outer, 2. Graphene/activation carbon composite layer, 3. polypropylene spunbond non-woven fabrics intermediate layer, 4. polypropylene spunbond non-woven fabrics internal layer.
Detailed description of the invention
With reference to Figure of description, the utility model is described in further detail:
As shown in Figure 1: a kind of mouth mask filter core for purifying PM2.5, it forms layered laminate by polypropylene spunbond non-woven fabrics skin 1, polypropylene spunbond non-woven fabrics internal layer 4, polypropylene spunbond non-woven fabrics intermediate layer 3, Graphene/activation carbon composite layer 2, and described Graphene/activation carbon composite layer 2 is placed on described polypropylene spunbond non-woven fabrics intermediate layer 3 as independent adsorption material bag; Described polypropylene spunbond non-woven fabrics is outer, form by PUR is bonding between Graphene/activation carbon composite layer and each layer of polypropylene spunbond non-woven fabrics internal layer.
Preferably, Graphene/activation carbon composite layer 2 also can be set between polypropylene spunbond non-woven fabrics intermediate layer 3 and polypropylene spunbond non-woven fabrics internal layer 4 or polypropylene spunbond non-woven fabrics skin 1;
Described Graphene/activation carbon composite layer 2 is Graphene and the composite layer activating charcoal; In use, both Graphene/activation carbon composite layer can be processed into slurry, be sprayed on described polypropylene spunbond non-woven fabrics intermediate layer 3, be placed on described polypropylene spunbond non-woven fabrics intermediate layer 3 as the independent adsorption material bag that can remove after also first Graphene/activation carbon composite can being processed into Graphene/activation carbon composite non-woven fabrics.
In addition, described activated carbon refers to the composition of one or more in all kinds of active carbon, NACF, Activated Carbon Nanotubes.
Further, uniform by some air-vents respectively on described polypropylene spunbond non-woven fabrics skin 1, polypropylene spunbond non-woven fabrics internal layer 4 and polypropylene spunbond non-woven fabrics intermediate layer 3, the aperture of described air-vent is 10um.
