Description

A kind of antibacterial and dustproof mask

technical field

The utility model belongs to the technical field of masks, in particular to a bacteria-removing and dust-proof mask.

Background technique

As a daily protective hygiene product, a mask covers the outside of the mouth and nose of a person, and can adhere and absorb dust particles in the air around the mouth and nasal cavity. In today's society, masks are widely used in industrial production fields such as precision processing, food and pharmaceuticals, and closed mining.

However, the masks currently widely used are usually made of single or multi-layer gauze or cotton cloth, which not only has problems such as poor dust absorption performance and lack of deodorization, but also has the disadvantages of infectious bacteria and Viruses are also difficult to achieve a good isolation effect. Therefore, developing a kind of broad-spectrum novel antibacterial and dust-removing mask with excellent adsorption properties and deodorizing and sterilizing functions has become a problem to be solved urgently in this field.

Utility model content

The purpose of the utility model is to provide a sterilizing and dustproof mask, which not only has good adsorption performance, but also has good deodorizing and sterilizing functions, and at the same time has a simple structure and is easy to produce and manufacture.

In order to achieve the above object, the utility model adopts the following technical scheme: a kind of antibacterial and dust-proof mask, which is composed of multi-layer cloth, the cloth is non-woven fabric or gauze, and at least one layer of the multi-layer cloth is Coated with nano-graphene coating or nano-titanium dioxide coating or nano-titanium dioxide and nano-graphene composite coating.

Simultaneously, the utility model can also be further realized through the following technical measures:

Preferably, the mask is made of three layers of cloth.

Preferably, at least one layer of the multi-layer cloth is provided with a nose bridge clip.

Preferably, the nano-titanium dioxide coating is an anatase-type nano-titanium dioxide coating.

Preferably, the composite coating of nano-titanium dioxide and nano-graphene is a composite coating of anatase nano-titanium dioxide and nano-graphene.

Further, the cloth coated with nano-titanium dioxide and nano-graphene composite coating is arranged between the outermost cloth and the innermost cloth of the mask.

Further, the nose clip is an aluminum-plastic nose clip.

The beneficial effects of the utility model are:

1), one of the technical solutions in the utility model is to coat the cloth of the mask with a nano-graphene coating. Compared with the activated carbon filter layer in the prior art, the graphene nano-material in the nano-graphene coating has a larger specific surface area, and can undergo a strong complexation reaction with organic pollutants to produce extremely strong adsorption , so that the nano-graphene coating in the utility model can not only absorb some dust and other inorganic small molecule particles in the surrounding air, but also show excellent adsorption properties for various bacteria, viruses and organic pollutants, thereby effectively Filter dust and prevent the invasion of germs.

2), Another technical solution in the utility model is to coat the cloth of the mask with a nano-titanium dioxide coating. The titanium dioxide nanomaterials in the nano-titanium dioxide coating have strong photocatalytic efficiency under the irradiation of ultraviolet light, sunlight or other light sources, so that surface water mist can be quickly removed, bacteria can be decomposed, and good antibacterial and deodorizing properties can be exerted. , anti-fog, sun protection and other functions.

3), the third technical solution in the utility model is to coat the cloth of the mask with a composite coating of nano-titanium dioxide and nano-graphene. The nano-titanium dioxide and nano-graphene composite coating is provided with graphene nanomaterials and titanium dioxide nanomaterials, so the utility model has excellent adsorption and filtration properties of graphene, and because the graphene nanomaterials have excellent electrical conductivity performance, which can promote the effective separation of electron-hole pairs, so that nano-titanium dioxide under the irradiation of ultraviolet light, sunlight or other light sources shows enhanced photocatalytic efficiency, further quickly removes surface water mist, decomposes bacteria, and exerts Good antibacterial, deodorant, anti-fog, sunscreen and other functions.

4) Compared with the current dust-proof masks, the anti-bacterial and dust-proof masks in this utility model have stronger adsorption performance and higher sterilization, deodorization and dust-proof effects, and the nano-coating is non-toxic and pollution-free. Simple and has a good market prospect.

Detailed ways

Below, the composite coating of nano-titanium dioxide and nano-graphene is taken as an example, and the utility model is further described in conjunction with the accompanying drawings.

The nano-titanium dioxide and the nano-graphene are uniformly dispersed in the absolute ethanol solution according to the mass ratio of 100:1-100:5, and the solutions are uniformly mixed by ultrasonic stirring. Then the above mixed solution is coated on the surface of the non-woven fabric or gauze carrier material by means of dipping, filling or coating. Subsequently, the carrier material is dried, dried and cured, washed and re-dried and cured. Finally, according to the usual mask processing method, the non-woven fabric or gauze loaded with the nano-titanium dioxide and nano-graphene composite coating is used as the middle layer, and the masks of various shapes are processed with ordinary non-woven fabric or gauze, and welded. Aluminum-plastic bridge of the nose clip and ear straps promptly obtain the nano-mask in the utility model.

As shown in Figure 1, the intermediate layer 2 that is arranged between the outer layer 1 and the inner layer 3 is the cloth that is coated with nano-titanium dioxide and nano-graphene composite coating, and the outer layer 1, the intermediate layer 2 and the inner layer 3 Together constitute the main body of the mask.

In addition, in the preparation process of nano-titanium dioxide, the graphene material can be evenly dispersed, and then the base materials such as non-woven fabric or gauze can be coated and modified by the above-mentioned method, and the anti-bacterial and dust-proof material in the utility model can also be obtained. Face mask.
