Description

Mask having an antibacterial wire part {Mask within anti-virus wiremodule}

The present invention relates to a mask in which a wire part inside the mask is made of an antibacterial material.

Air is one of the basic elements that sustain human life, and only with air can life exist. However, with the development of industry and science and technology, air pollution in the present society is becoming increasingly serious, and although it cannot be confirmed with the naked eye, the concentration of PM2.5 and bacteria in the air is gradually increasing.

According to the survey results, lung cancer in 2016 has already surpassed the figures of gastric and liver cancer, which are publicly known as one of the cancers with the highest incidence and mortality. In addition, it has been shown that more and more people get lung cancer even without habits such as smoking or drinking.

Wearing a mask to combat serious air pollution is the most direct method, and masks with various functions are on the market. Although most masks have some degree of PM2.5 isolation efficacy, they only have an isolation function and do not have a sterilization function. In addition, if most of the masks are knitted fabrics and are used for a long time, there is a risk that bacteria will grow on the mask and harm the health of the wearer. In addition, if such a mask is worn for a long time, the mask becomes contaminated with bacteria in one's mouth, and odors in the mouth are not deodorized.

The conventional mask functions to filter external dust, but has no function to block the intrusion of external viral bacteria. In addition, due to moisture when the user breathes, bacteria multiply on the mask, and these bacteria can cause infection, which can lead to infections such as respiratory syndrome such as yellow sand or SARS, or to be transmitted to other people. there is.

In the recent global outbreak of Corona 19, wearing such a mask is becoming a daily routine, and interest in antibacterial and sterilizing functions is rapidly increasing.

1 is a conceptual diagram illustrating the structure of a mask (hereinafter, referred to as 'the present invention') according to an embodiment of the present invention.

Referring to FIG. 1, the present invention includes a mask body part 110 that is formed to be in close contact with a user's face, and a wire member disposed inside the mask body part 100 and made of a material that can be bent. It may be configured to include an antibacterial wire part 120 and a fixing band part 200 installed in a structure that is fixed to both sides of the mask body part 110 and extends.

The structure of the mask shown in FIG. 1 exemplifies the structure of some of the structures of various types of masks, and the overall shape or appearance is not necessarily limited thereto.

The mask presented as an example of the present invention includes a mask body part 110, and this mask body part 110 has some different structures depending on various types of masks, but in general, the mask front part 112 and the upper part ( 113) and the lower end 111 may be implemented as a structure.

In the case of the fixing band 200, a length adjustment groove 135 for length adjustment may be provided, or a fixing portion 115 and a welding portion 130 for fixing the fixing band portion to the mask body 110 may be provided. there is.

A characteristic structure in the present invention is to provide the antibacterial wire unit 120 inside the upper end 113 of the mask of various shapes.

The antibacterial wire unit 120 according to the present invention can be applied to all types of mask structures commercially available in the market, including a mask structure having a wire of a material that bends to fit the shape of the nose when the user wears the mask. , the wire provided in the mask currently on the market is simply bendable, and is merely a structure in which the outer shape of a plastic resin is coated on the metal core of the structure.

The antibacterial wire part 120 applied in the present invention includes a wire receiving part 121 having an accommodating area on the inner surface of the mask body 110 and a wire member accommodating in the wire accommodating part 121 ( 122), and the wire member 122 may have a structure in which an antibacterial coating member (B) is coated on the outer surface of the wire (A) having a bendable structure.

In particular, in the present invention, it is characterized in that the structure of the antibacterial wire part 120 is implemented to include an antibacterial material, chlorine dioxide (CLO2), in the synthetic resin part coated on the outer shaft of the wire member.

Chlorine dioxide (CLO2), one of the oxides of chlorine, is a class of chemicals that release reactive oxygen species and is very effective when used against infectious microorganisms and viruses. It has a mechanism of action to eradicate infectious microorganisms and primitive bacteria by binding specific white blood cells with ozone, hypochlorite, and periodonate.

That is, the principle of this action mechanism can be explained as follows.

Chlorine dioxide (CLO2) is an inorganic (carbon-free) sodium salt with only an electronegative element that is electrostatically bound (covalent and coordination-covalent, Fig. 2). The chemical structure of CLO2 is pH dependent. That is, the stability or instability of this material is largely determined by the concentration of hydrogen ions (H+ or protons) in the surrounding medium.

Under acidic conditions, sodium chlorite becomes unstable and decomposes into various products such as hypochlorite ions and nascent (atomic) oxygen, not limited to chloride ions. This is why CLO2 is buffered when stored in a bottle for a long time. In acidic conditions, CLO2 produces a neutral molecule with three electronegative atoms bound by covalent and coordinate covalent bonds. In this aggregate, a single atom of highly reactive generating oxygen is released to the target microorganism. Oxygen generated is an active substance of CLO2, and unless it is isolated, antiviral, antibacterial and anti-wind activity is not achieved.

Viruses generally consist of an outer shell or coating of a protein that encapsulates a nucleic acid, which can be either DNA or RNA (eg retroviruses). The backbone of a nucleic acid contains a derivative of phosphoric acid (H3PO4; a very strong acid) in which two of the original three hydroxyl groups (-OH) are replaced, leaving only one active hydroxyl group per phosphoric acid.

Once bound to the appropriate cell type, the nucleic acid component of the virus is injected into the cell and in several ways takes over the cell's protein synthesis process. A specific portion of the viral nucleic acid consists of genes responsible for the replication of the coat. Nucleic acid components are replicated by a process known as "base pairing" in which each base of the original strand attracts and binds to its corresponding base via hydrogen bonding. That is, they form pairs (A-T and C-G; ) through hydrogen bonding. The result of this is to replicate the complete virus until the cell explodes (releasing many additional virus particles into the surrounding medium). In the presence of these acidic nucleic acids, ClO2 molecules become unstable and release oxygen to the medium.

Nucleic acids have many properties in common with both RNA and DNA; In fact, the two are almost chemically identical. Each consists of alternating sugar chains and phosphate groups, known as "phosphate backbones". Attached to a specific carbon of each deoxyribose group is an organic ring compound known as a "base." Taken together, the bases found in DNA are of four types: guanine (G); Only cytosine (C), adenine (A) and thymine (T). What makes one section of DNA different from others is the arrangement of these four units along the chain. RNA is chemically different from DNA in that the base thymine is replaced by the base uracil (U), which represents a very subtle biochemical difference. There are also subtle differences in the sugar deoxyribose.

Basic guanine, found in both RNA and DNA, is very sensitive to oxidation and forms 8-oxoguanine as a product of oxidation. The release of CLO2 results in oxidation of the guanine residue with the formation of 8-oxoguanine, thereby disallowing replication of the viral nucleic acid by base pairing. Replication of the protein coat can continue, but the formation of a fully functional virus is blocked by CLO2 oxidation. According to this principle, chlorine dioxide has an effect of blocking the formation of viruses, and it is also possible to act as an antibacterial agent.

The principle of action as an antibacterial agent is to implement the action of inhibiting the formation of mold bacteria, which is considered a chlorophyll-free plant lacking the ability to produce carbohydrates from sunlight and carbon dioxide. The fungus probably originated in an oxygen-free atmosphere, and some tolerate low levels of oxygen. Most bacteria prefer an oxygen-poor environment and live best under these conditions. Fungi get their energy from the breakdown of existing organic matter (via enzymatic activity) and can be considered parasites in this respect.

Mycelial fungi are sensitive to the destructive action of CLO2 because of their low resistance to oxygen generating and acidic media (which can survive the separation of organic acids). An example of a human pathogen is Candida albican, which injures fingers and toenails.

Another example is athlete's foot fungus, which thrives between the toes in a humid environment, and ringworms (which cause homeostasis and produce large amounts of mycotoxins) that thrive in dead cells of the skin. It is clear that CLO2 is intrinsically activated only by viruses such as acidic bacteria and fungi. Another clinical cytotoxin oxidizer, CL02, is not the only clinical antibacterial agent. Another component that provides free radicals is hydrogen peroxide, which has been used in the treatment of arthritis, cancer and other metabolic diseases. Hydrogen peroxide is commercially available in low concentrations for the treatment of local microbial infections.

In the present invention, by using the characteristics of chlorine dioxide (CLO2), the synthetic resin material (hereinafter, referred to as the main material) coated on the outer skin of the wire structure can contain chlorine dioxide (CLO2). However, chlorine dioxide is toxic when the concentration in the material contained is 1% (10,000ppm) or more, and in the present invention, the concentration of chlorine dioxide (CLO2) contained in the synthetic resin is 1000ppm or less. it is preferable

More preferably, the concentration of chlorine dioxide (CLO2) contained in the synthetic resin is 100ppm or less.

When the structure of this antibacterial wire member is disposed on the upper part of the mask, as shown in FIG. 2 , the user wears a mask (mask body part: 110) and bends the wire according to the shape of his or her nose If worn as (antibacterial wire part: 120), then, if breathing is performed, chlorine dioxide (CLO2) is gradually decomposed (contacted with air) in the wire epidermis part, and thus has a strong antibacterial or sterilizing action. will perform This acts as an antibacterial gas that stays in the space between the inside of the mask and the user's face, and serves as a sterilizing action on the inner surface of the mask. These antibacterial and sterilizing effects show a sterilization effect of 90% or more, and a maximum sterilization effect of 99.9% can be realized.

The antibacterial wire part 120 shown in FIG. 1 has a structure in which a space for inserting the above-described antibacterial wire member is provided (hereinafter, referred to as an 'insertion guide part') therein, and in the embodiment of the present invention Although the structure in which one wire member is inserted has been exemplified, the present invention is not limited thereto, and it is of course possible to implement a structure in which two or more antibacterial wire members are interpolated.

In the structure of FIG. 1, various plastic resins or rubber resins may be applied as the coating resin (main material) for coating the outer surface of the wire of the antibacterial wire part. As an example, the rubber resin may be EPR (ethylene propylene rubber), EPDM (ethylene-propylene-non conjugated diene-terpolymer) copolymerized with 15 to 20 wt% of ENB (ethylene norbornene), and polyolefin-based rubber.

EPR (ethylene propylene rubber) is an amorphous polymer material obtained by copolymerizing ethylene and propylene, and EPDM is a copolymer of ethylene, propylene and diene, It has electrical properties, so it is advantageous to apply to products used in harsh environments.

ENB may serve as a crosslinking point for vulcanization of the rubber resin, and if the content of ENB is less than 15% by weight, the crosslinking rate and crosslinking density may decrease, thereby reducing the mechanical properties of the covering material composition, and if it exceeds 20% by weight of rubber resin

The crosslink density may be excessive, reducing the flexibility of the cable. In addition, it is preferable to copolymerize 15 to 20% by weight of ENB among dienes so that EPDM can be prepared without a separate crosslinking agent.

Or, as another example, as the main material of synthetic resin, ethylene propylene rubber (EPR) is used because it is flexible and has excellent long-term insulation ability. can More preferably, EPDM can be used. It is preferable to use 20 ~ 80 phr of ethylene propylene rubber, but if it is less than 20 phr, there is a limit in flexibility due to high hardness, and if it exceeds 80 phr, there is a limit due to deterioration of extrusion characteristics and mechanical properties, so it is recommended to use within the above range. good night.

Alternatively, the polyolefin resin (PO)) is for improving the wire extrudability and tensile strength of ethylene propylene rubber, and one or more selected from the group consisting of LLDPE, LDPE, VLDPE, MDPE, and POE can be selected and used. , it is preferable to use 10 to 80 phr. If it is less than 10 phr, there is a limit to the extrusion properties, and if it is more than 80 phr, the hardness is high and flexibility is limited, so it is recommended to use it within the above range. In particular, ethylene propylene rubber has a property of sticking to each other because it is rubber, but it does not stick to each other after it is molded into pellets by blending polyolefin resin (PO). In addition, peroxide is usually added to ethylene propylene rubber, and crosslinking can be performed at high temperature and high pressure.

It is possible to use one or a combination of two or more of the main material as such a synthetic resin, and in some cases, as a filler to keep the external shape constant, it is composed of SiO2, CaCO3, Mg(OH)2, and hydrotalcite. It is preferable to use a silane-coated surface of one or more selected from the group having an average particle size of 0.5 to 1 μ. At this time, if the average particle size is less than 0.5 μ, there is a limit to the dispersion characteristics, and if it is more than 1 μ, there is a limit to the surface properties of the wire, so it is recommended to use it within the above range.

As described above, the technical idea of the present invention has been specifically described in the preferred embodiment, but the preferred embodiment is for the purpose of explanation and not for limitation. As such, those skilled in the art will be able to understand that various embodiments are possible through the combination of the embodiments of the present invention within the scope of the technical spirit of the present invention.
