Nano silver ion sterilizing mask

[ technical field ] A method for producing a semiconductor device

The utility model relates to a gauze mask especially relates to nanometer silver ion virus killing gauze mask.

[ background of the invention ]

The serial researches on the aerodynamic of the mouth mask prove that: 1, PM2.5 can not directly penetrate through pores of the outer isolation layer along with air, but can be electrostatically adsorbed by fibers interwoven by the outer isolation layer; 2, moisture generated by breathing can quickly wet the isolating fibers of the outer isolating layer, and the wet fibers can firmly adsorb particulate matters and form agglomerated jelly; 3, about 5% -8% of the fine particles will enter the filter layer at 1/3, and these fine particles are not carried to the inside of the filter layer by the fine particles of the breathing gas without the breathing gas undergoing repeated mechanical movements, which takes a certain amount of time. According to the research results, the nano silver ion sterilizing mask can be produced in a targeted manner.

[ summary of the invention ]

The utility model discloses a aim at solving the problem of gauze mask virus killing and provide a nanometer silver ion virus killing gauze mask, this gauze mask is close to outside isolation layer department at the filter layer and is provided with polypropylene and spouts the silk layer, and polypropylene is spouted and is rich in the silk layer and have nanometer silver particle, and nanometer silver particle produces silver ion because temperature and humidity transform activate very easily in the respiratory process, utilizes silver ion to realize the virus killing function to the effect of killing of virus.

In order to achieve the above object, the utility model discloses a nano silver ion virus killing mask, including outside isolation layer 1, filter layer and the veneer layer 4 that sets gradually, the filter layer include that polypropylene spouts a layer 2 and an isolation cotton layer 3, polypropylene spout and contain nanometer silver particle in the layer 2, polypropylene spouts a layer 2 and is close to outside isolation layer 1, isolation cotton layer 3 is close to veneer layer 4.

Furthermore, the thickness of the filter layer is 0.5-0.8 mm. The thickness of the polypropylene spinning layer 2 accounts for 1/4-1/2 of the thickness of the filter layer.

The utility model discloses a contribution lies in providing a nanometer silver ion virus killing gauze mask, according to the aerodynamic research achievement of gauze mask, the pioneering sets up polypropylene at filter layer fine grain enrichment face and spouts the silk layer, polypropylene spouts the silk layer and is rich in nanometer silver particle, nanometer silver particle is the activation phenomenon under the higher temperature and humidity environment of respiration in-process is obvious, produce a large amount of silver ions, the virus that utilizes silver ion's virus killing effect to enrichment face kills, reach the disinfection purpose, when the virus is taken to polypropylene by air current mechanical motion and spouts the silk layer, it has lost activity no longer has the toxicity nature.

Fig. 1 is a schematic structural diagram of the present invention.

[ detailed description ] embodiments

The following examples are further to explain and supplement the present invention, and do not constitute any limitation to the present invention.

Example 1

As shown in fig. 1, the nano silver ion disinfecting mask of the present embodiment includes an outer isolation layer 1, a filter layer and a laminated layer 4, which are sequentially disposed, the filter layer includes a polypropylene spinning layer 2 and an isolation cotton layer 3, the polypropylene spinning layer 2 contains nano silver particles, the polypropylene spinning layer 2 is close to the outer isolation layer 1, and the isolation cotton layer 3 is close to the laminated layer 4.

Outside isolation layer 1 is activated carbon cloth or water-resistant anti-oil fabric, and veneer layer 4 is the non-woven fabrics layer, and the isolation cotton layer 3 of filter layer is through the mode preparation that spouts the silk, and the polypropylene of filter layer spouts the silk layer 2 and is to place the silver particle of nanometer level in the polypropylene solution, then spouts the silk preparation, makes nanometer silver particle firmly fix in polypropylene spouts the silk layer 2, and nanometer silver particle is difficult to spout the production with polypropylene and drops on the silk layer 2. In the using process, due to the respiration effect, the nano-silver particles rich in the polypropylene spinning layer 2 are activated in the environment with slightly high temperature and high humidity to generate a large amount of silver ions, so that the virus is inactivated by utilizing the virus killing characteristic of the silver ions, and the virus killing purpose is achieved.

Example 2

As shown in FIG. 1, the thickness of the filter layer in this embodiment is 0.5 to 0.8 mm. The thickness of the polypropylene spinning layer 2 accounts for 1/4-1/2 of the thickness of the filter layer. According to the research result of the aerodynamics of the mask, viruses passing through the outer isolation layer 1 are generally concentrated at 1/3 of the filter layer, so that the thickness of the polypropylene spinning layer 2 is set to be 1/4 to 1/2 of the thickness of the filter layer, the fine particle enrichment surfaces are all the polypropylene spinning layer 2, and the purpose of disinfection is achieved by utilizing the nano-silver particles rich in the polypropylene spinning layer 2 to generate a large amount of silver ions.

Although the present invention has been described in connection with the above embodiments, the scope of the present invention is not limited thereto, and modifications, replacements, and the like to the above members are all within the scope of the claims of the present invention without departing from the concept of the present invention.
