Problems solved by technology

Commonly used protective masks mainly include ordinary masks, disposable medical masks, medical surgical masks, particle protective masks, medical protective masks, etc. Now there are also anti-smog electric masks, but the cost is high and the weight is heavy
Ordinary cotton, gauze or non-woven masks have been gradually phased out due to their inability to effectively block smog and bacteria and viruses
And there are following problems in the mouth mask of prior art: 1, mostly are disposable use products, can not clean and disinfect with methods such as conventional steaming, alcohol, use time is short, cause the great waste of resources; 2, mostly one-piece structure , can not be reused, and the average comprehensive use cost is high; 3. Ordinary medical masks and medical surgical masks cannot effectively block smog particles and pathogenic microorganisms smaller than 2.5 microns due to their low degr

Embodiment 1

[0049] The outer layer and inner layer of the barrier filter are made of polypropylene spunbonded non-woven fabric, which is pre-paved, baked, loaded with composite catalytic catalyst material and made of water-repellent finishing;

[0050] The middle layer uses a layer of melt-blown polypropylene non-woven fabric treated with electrostatic electret, a layer of activated carbon felt and a layer of hygroscopic spunlace non-woven fabric. Catalytic catalyst material.

[0051] The outer layer of polypropylene spunbond non-woven fabric, melt-blown polypropylene non-woven fabric, carbon felt, spunlace non-woven fabric and inner layer of polypropylene spunbond non-woven fabric are stacked together in sequence, and the ultrasonic non-woven fabric is used for spot welding Machine spot welded into one piece, or glued or sewn into one piece. According to the inner size and shape of the inner surface 16 of the groove ring in the middle of the cover, the matching barrier filter is cut.

Embodiment 2

[0054] The outer layer and inner layer of the barrier filter are made of polypropylene spunbonded non-woven fabric, which is pre-padded, baked, loaded with commercially available antibacterial agents, and water-repellent finishing; the middle layer is made of 3 layers of melt blown with electrostatic electret treatment Polypropylene nonwoven.

[0055] The outer layer of polypropylene spunbond non-woven fabric, three layers of melt-blown polypropylene non-woven fabric and the inner layer of polypropylene spunbonded non-woven fabric are stacked together in sequence, and are welded together by ultrasonic non-woven fabric spot welding machine, or use Glued or sewn into one piece. According to the inner size and shape of the inner surface 16 of the groove ring in the middle of the cover, the matching barrier filter is cut.

[0056] Put the barrier filter flat in the groove ring in the middle of the face cover, the outer layer 20 of the barrier filter is in close contact with the i...

Embodiment 3

[0058] The outer layer and inner layer of the barrier filter are made of polypropylene spunbonded non-woven fabrics, which are pre-padded, baked, loaded with composite catalytic catalyst materials and treated for water repellency; the middle layer is made of 1 layer of polytetrafluoroethylene PTFE nano-film.

Abstract

The invention relates to a reusable bacteria-haze-virus prevention mask and a preparation method thereof. The reusable bacteria-haze-virus prevention mask comprises a silica gel housing, a surface cover separated from the silica gel housing, and a replaceable antibacterial blocking filter disc which is arranged between the housing and the surface cover in a sealing mode through physical dimensioncooperation of the silica gel housing and the surface cover. The silica gel housing and the surface cover which are arranged in a separated mode can be cleaned and disinfected by using common methodssuch as water cleaning, stewing and alcohol disinfection and can be repeatedly used, and the service life is prolonged; the silica gel housing designed through 3D face engineering is reasonable in structure and high in sealing degree with the face, the surface cover is porous, the air feeding and exhausting quantity is large, and the protective efficiency and air permeability of the mask are coordinated very well; and the blocking filter disc can be independently and regularly replaced and replaced with a cut common medical mask or cut medical surgical mask for emergency, and the average comprehensive use cost is greatly reduced. The bacteria-haze-virus prevention mask is reusable and has the good bacteria-haze-virus prevention function.

Description

technical field [0001] The invention relates to the field of masks and a preparation method, in particular to a reusable (recyclable) antibacterial and haze-proof mask with a replaceable antibacterial barrier filter and washable, sterilizable, anti-spray, separable silica gel cover and face cover Antivirus mask and preparation method thereof. Background technique [0002] Mask is a commonly used sanitary protection product, especially during the outbreak and epidemic of infectious diseases, wearing a mask is one of the essential and effective means of personal protection. In addition, with the development of industrialization and urbanization, atmospheric air quality is deteriorating, and smog weather occurs frequently. The smog contains a large number of inhalable particles, sulfuric acid, nitric acid, organic hydrocarbons and other particles that are extremely harmful to human health. People often need to wear masks when going out. Commonly used protective masks mainly i...
