Description

  The present invention relates to a mask that is worn on the face and covers the nose and mouth in order to combat air pollution in living spaces and the contamination of viruses and pathogens such as severe acute respiratory syndrome (SARS). Acts on oxides, suspended solids and various pathogens suspended in the air, especially viruses and pathogens such as SARS, and decomposes and adsorbs inside the mask, allowing only sterile and clean air to breathe. The present invention relates to a facial mask.

  Conventional masks that are worn on the face and cover the nose and mouth are usually made up of multiple thin layers of fine fabric such as cotton gauze or non-woven fabric that are folded into the mask body, and replacement gauze is inserted inside. Then, a thin locking string for locking this to the ear or the head is attached to the left and right sides of the mask body. Wear these masks so that people with colds and other infectious diseases do not spread their source of infection around them, such as exhaling or coughing, or do not breathe cold air directly. Or wear it when a healthy person is polluted of the air or when an infectious disease is epidemic to prevent inhalation of air pollutants or to prevent infection. That is, the mask worn on the face is used to maintain and maintain one's own health or to prevent transmission of the infection to others.

  A mask worn on such a face is usually formed into a rectangular mask body by folding a sterilized cloth such as a gauze or a nonwoven fabric made of cotton or the like into a size covering the nose and mouth as described above. On both sides of the mask main body, thin locking cords for locking to the ears and the back of the head are inserted respectively. To ensure that the nose and mouth are covered, such masks are provided with multiple overlapping folds in the lateral direction of the mask body, and disinfected gauze is placed inside the mask that directly contacts the nose and mouth. There is one that is arranged as a separate body for replacement.

  On the other hand, the inventors have developed a woven fabric made of glass fibers having a titanium dioxide layer formed on the surface by calcination and having a photocatalytic effect on organic matter decomposition (see Patent Document 1 or Patent Document 2).

  The problem to be solved by the present invention is to wear on the face to prevent respiratory disorders due to air pollution, infectious diseases such as colds, and especially infections due to viruses and pathogens such as severe acute respiratory syndrome (SARS). By improving the mask that covers the nose and mouth, it absorbs airborne substances so that they are not included in breath, and receives natural light or ultraviolet rays from ultraviolet lamps to kill and decompose viruses and pathogens It is an object of the present invention to provide a household mask or a medical mask that can be worn on the face.

  Means of the present invention for solving the above-mentioned problems are, in the invention of claim 1, a ceramic fired product containing an outer layer 4 made of a glass fiber gauze 2 and a activated carbon 5 on which a photocatalytic substance 3 having an organic substance decomposing action is fired and adhered. A mask body 11 covering the nose and mouth made of a three-layer polymer 10 formed from an intermediate layer 7 made of a nonwoven fabric 6 impregnated and coated with an inner layer 9 made of cotton gauze 8, and two side portions 12 of the mask body 11. A face-fitting mask 1 having a photocatalytic function and an adsorbing function, characterized by having a locking string 13 that can be locked to an ear or a head.

  According to the invention of claim 2, the activated carbon 5 is bamboo charcoal, the face-fitting mask 1 having a photocatalytic function and an adsorbing function according to claim 1 characterized by the above-mentioned.

  The face-wearing mask of the present invention has an outermost layer of an inorganic glass fiber gauze in which a photocatalytic substance such as titanium dioxide is baked and adhered to the surface, and activated carbon such as charcoal baked in the form of white charcoal on the inner side of the outermost layer, preferably. The mask body used was a three-layer polymerized layer composed of an intermediate layer of a nonwoven fabric in which ceramic powder containing activated charcoal powder of bamboo charcoal was dispersed and held with an inorganic binder, and an inner layer of cotton gauze.

  Therefore, the mask of the present invention is worn on the face in addition to simply not allowing airborne substances to pass as much as possible as in the conventional mask, or directly preventing viruses and pathogens from entering the body orally. By contacting airborne substances and viruses and other bacteria, especially organic substances such as viruses such as SARS, with a photocatalytic substance such as titanium dioxide fired on the outer layer of the glass fiber gauze of the mask, it is exposed to sunlight and ultraviolet rays from an ultraviolet lamp. Decompose and kill to prevent entry into the body. Bacteria, viruses or airborne substances that have passed through the outer layer without contacting the photocatalyst substance and airborne substances are adsorbed and removed by powder of activated carbon such as white charcoal made of charcoal, preferably bamboo charcoal. In addition, the carrier of the present invention can prevent the bacteria and viruses from dispersing into the atmosphere by wearing the mask of the present invention by wearing the mask of the present invention. Play.

  The mask of the present invention, especially, the glass fiber to which the photocatalyst is attached decomposes organic substances and bacteria, but as described above, even if the fine bacteria pass through the photocatalyst without contact, bamboo charcoal with excellent adsorption properties Such a pass-through substance can be adsorbed and removed by a nonwoven fabric filter to which activated carbon made of white charcoal is adhered. The bacteria adsorbed on the bamboo charcoal filter are exhaled, sent again to the glass fiber side to which the photocatalyst has been attached, and are killed by catalytic decomposition. In the mask of the present invention, the binder of the activated carbon bamboo charcoal filter uses an inorganic binder, so the filter itself is not decomposed by the photocatalyst, and the decomposition power of the photocatalyst and the adsorption power of the activated carbon such as bamboo charcoal are used. A synergistic effect can be expected.

  The best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a view showing a mask 1 of the present invention. FIG. 2 is a diagram schematically showing a three-layer structure of the mask main body 11.

  The mask 1 of the present invention is made of a glass fiber gauze 2 having an outer layer 4 to which a photocatalytic substance 3 such as titanium dioxide having an organic substance decomposing action is baked and adhered. This photocatalytic substance is formed on the outer peripheral surface of the glass fiber by dipping the glass fiber in a titania sol, pulling it up, and naturally drying it to obtain a titania gel, which is heated and fired in a high-temperature furnace at a processing temperature of 450 to 650 ° C. A titanium layer is formed by adhesion.

  On the other hand, the intermediate layer 7 of the mask body 1 is made of a nonwoven fabric 6 impregnated with a fired ceramic material containing activated carbon 5. A description will be given of the intermediate layer 7 containing charcoal powder, which is activated carbon, particularly bamboo charcoal, and a bamboo charcoal filter made of bamboo charcoal. The bamboo charcoal filter of the intermediate layer 7 is prepared by first mixing bamboo charcoal powder and ceramic powder such as porcelain clay in a certain ratio, adding water, kneading, shaping and drying. The powder is crushed into particles to obtain a fired bamboo charcoal powder. Next, 5 kg of this fired bamboo charcoal ceramic powder is mixed per 20 kg of the total amount, and the mixture is liquefied with an inorganic binder. The layer 7 is a bamboo charcoal filter. As a result, since the bamboo charcoal filter is covered with the polyester fiber by the inorganic binder as described above, the nonwoven fabric of the polyester itself is not decomposed by the photocatalyst. The method of manufacturing the intermediate layer 7 is the same for charcoal such as white charcoal.

  Further, the innermost layer of the three-layer polymerized layer 10 of the mask 1 is formed from an inner layer 9 formed of cotton gauze 8.

  As shown in FIG. 1, a mask body 11 covering a nose and a mouth made of a three-layered polymer layer 10 of the mask 1 is placed on both left and right side portions 12 of the mask body 11 so that the mask body 11 can be actually worn. A conventional locking cord 13 for locking to the ear or head is inserted. Then, at the time of wearing, a gauze for replacement is applied to the inside of the three-layered polymerized layer 10 of the mask body 11 and worn.
