Description

Antiboitic Mask And The Manufacturing Method Thereof

The present invention relates to an antibacterial mask and a method for manufacturing the same, and more specifically, metal ions to maintain antibacterial activity on the surface (primary filter) and to (secondary filter) of a face mask, in particular, a mask for yellow dust and prevention. It relates to an antibacterial mask coated on the non-woven fabric to block transmission from various microorganisms or bacterial pathogens and to provide a sanitary function, and a method for manufacturing the same.

In the past, there was no case of applying an antibacterial coating to the surface of the mask, but recently there is a tendency to manufacture antibacterial masks under the influence of the Corona 19 virus. In this case, in most cases, metal nanoparticles or general organic antibacterial agents are usually used, and the problem of safety for nanomaterials and the harmfulness of organic antibacterial agents to the human body remains to be solved.

Since the filter nonwoven fabric of the innermost face part of the mask for yellow dust and prevention is the surface that comes into direct contact with the skin, if other materials are coated, there is a possibility that the material may be inhaled by the respiratory system, so the coating treatment is not applied. In addition, if inorganic or metal particles are used, there is also a problem that a binder must be used due to weak adhesion. none.

Masks for yellow dust and quarantine are usually made of 3 to 4 layers (some 5 layers) of non-woven fabric, and except for the face filter and melt blown (MB) filter, the outside or inside can be coated.

The melt blown (MB) filter, which has a static generating function, can also affect the mask blocking function when other materials are coated, so there are many obstacles to surface treatment with metal particles, organic compounds, or inorganic materials.

In general, the size of metal particles from 1 nm to 100 nm is defined as a nano material, which is regulated to be used only when the risk and safety are proven worldwide. The reality is that it requires a lot of time and money to do it.

In the present invention, metal ions with the most compatibility and excellent antibacterial activity were selected, and an appropriate combination ratio of silver (Ag), copper (Cu), and zinc (Zn) ions was selected through a number of experiments using them alone or in combination. .

Roller coating does not limit the size or material of the roller. It may include silicone coating by attaching silicone to the roller drum.

After being coated, it is dried through a drying unit 4-3 and loaded on the loading unit 4-4.

After making the mask primary filter or secondary filter, when antibacterial/anti-fungal coating is applied as post-processing, roller coating is performed as shown in FIG. 3 or spray coating is applied as shown in FIG. It is not limited to coating.

As the metal particles or ionic material used in the present invention, silver (Ag), copper (Cu), and zinc (Zn) are used.

The silver (Ag) used is prepared by selecting one of silver nitrate (AgNO3), silver acetate (AgC2H3O2), and silver chloride (AgCl).

Silver (Ag) ions are made from silver nitrate (AgNO3), silver acetate (AgC2H3O2), and silver chloride (AgCl) as raw materials, in ultrapure water (electrical resistance value of 4㏁ or more), ethanol (Ethanol), isopropyl alcohol (IPA) in a solvent. One or two or more are selected and used as a solvent.

The zinc (Zn) used in the present invention is prepared by selecting one of zinc nitrate hexahydrate (Zn(NO3)2 .6H2O) and zinc chloride (ZnCl2), and the zinc (Zn) ion is zinc nitrate hexahydrate. Using (Zn(NO3)2·6H2O) and zinc chloride (ZnCl2) as raw materials, one or more of the solvents of ultrapure water (electrical resistance value 4㏁ or more), ethanol (Ethanol), and isopropyl alcohol (IPA) Select and use as a solvent.

Copper (Cu) used in the present invention is prepared by selecting one of copper nitrate trihydrate (Cu(NO3)2·3H2O), copper chloride (CuCl2·2H2O), and copper sulfide (Cu2S).

Copper (Cu) ions are made from copper nitrate trihydrate (Cu(NO3)2·3H2O), copper chloride (CuCl2·2H2O), copper sulfide (Cu2S) with ultrapure water (electrical resistance value of 4㏁ or more), ethanol (Ethanol), One or more of isopropyl alcohol (IPA) solvents are selected and used as the solvent.

The present invention is to form an antibacterial function by roller-coating or spray-coating a metal antibacterial agent (Ag, Cu, Zn) that exhibits excellent antibacterial activity on the nonwoven fabric of the mask for yellow dust and prevention. Instead of using , the metal is ionized and used as an ionic substance that stabilizes it, and the concentration used is the total concentration of each ionic substance at a concentration of 30 to 1,200 ppm.

The composition ratio of metal ions used in the present invention in order to have an antibacterial function on the surface of the outer (primary filter) or to (secondary filter) of the mask nonwoven fabric is as follows.

When silver (Ag) is used alone, the concentration is set to 20-50 ppm.

When copper (Cu) is used alone, the concentration is set to 60 to 100 ppm.

When zinc (Zn) is used alone, its concentration is set to 500 to 1,200 ppm.

When silver (Ag) and copper (Cu) are used together, the concentration used is 10 to 20 ppm for silver (Ag) and 40 to 80 ppm for copper (Cu).

When silver (Ag) and zinc (Zn) are used together, the concentration used is 10 to 20 ppm for silver (Ag) and 500 to 800 ppm for zinc (Zn).

When copper (Cu) and zinc (Zn) are used together, the concentration used is 40 to 80 ppm for copper (Cu) and 500 to 800 ppm for zinc (Zn).

When silver (Ag), copper (Cu) and zinc (Zn) are used together, the concentration used is 10 to 20 ppm for silver (Ag), 40 to 80 ppm for copper (Cu), and 400 to 600 ppm for zinc (Zn) (Table). see 1).

In such a composition ratio, the mask nonwoven fabric for yellow dust and prevention is mainly made of polypropylene, and this polypropylene has a hydrophobic group that is not friendly with water, so metal ions of silver (Ag), zinc (Zn), and copper (Cu) above. By selecting a combination from among them, there is no adhesion and color contamination, and it is possible to maintain excellent antibacterial power without entering the respiratory tract.

Metal ions can be prevented from entering the respiratory tract while maintaining excellent antibacterial activity without being separated from the mask nonwoven fabric due to excellent adhesion.

Regarding silver, copper, and zinc, silver (Ag) is mainly used when instantaneous sterilization power is required, and when anti-fungal power is required as the main effect, the color of the raw material (copper is blue or green, silver is yellow) In cases where dark brown) is not a problem, use copper alone or use copper and silver or copper and zinc in combination. Alternatively, zinc and silver or zinc and copper are used in parallel, and the amount of copper and silver used is selected from the range of use so as not to cause a problem to the product, although the color is expressed.

Each metal acts as a cation (plus ion) to destroy the cell membrane of microorganisms or to inhibit proliferation by interfering with metabolism. The range of use was set in consideration of the minimum growth inhibitory concentration (MICs) for bacteria in each composition ratio, and the inhibitory power of mold, which is not desperately needed, is not considered. In particular, it is a concentration that takes into account about 30% of the loss that is consumed by scattering during spray coating.

(Example 1) KF 94 antibacterial mask non-woven fabric test (see Table 2)

The surface of the primary filter nonwoven fabric of the mask was spray-coated, and the raw material used was silver (Ag) ions, and the concentration used was 50 ppm silver (Ag) (spray twice at 25 PPM concentration). For silver (Ag), silver ions (Ag+) prepared from silver chloride were used. Test results Super bacteria (methicillin-resistant Staphylococcus aureus: MRSA. Staphylococcus aureus ATCC 33591), Staphylococcus aureus ATCC 6538P, Escherichia coli ATCC 8739, Pseudomonas aeruginosa, ATCC 27853 pneumoniae ATCC 435) were all proven to have an antibacterial activity of 99.9%.

(Example 2) Block rate test after antibacterial treatment of mask for KF94 quarantine (Table 3)

(See FIG. 5) In (Example 2) of Table 3, the antibacterially treated sample in (Example 1) was used as the same sample as it is, and it was confirmed how much the KF94 mask with antibacterial activity affects the blocking rate. As a test, the test was conducted in the same way as the KF94 quarantine mask blocking rate test prescribed by the Ministry of Food and Drug Safety (S2). In the face intake resistance value test, when air was passed at a continuous flow rate of 30 L/min, both the average value before pretreatment (28.13pa) and the average value after pretreatment (30.57pa) passed the reference value of 70 Pa or less of the facial intake resistance value. In the brine and paraffin oil test, in the sample before and after pretreatment, the average value before pretreatment was 99.8% for the brine aerosol, and there was no difference in the blocking rate with 99.8% blocking rate after pretreatment. In the case of the paraffin oil test, the average value before pretreatment was 99.5% After pretreatment, the blocking rate was maintained at a value of 94% or more, which is the standard value of 99.47% (S4). Therefore, it is the experimental result confirming that it does not affect the mask blocking rate while maintaining the antibacterial power.

(Example 3) After antibacterial spray on the KF 94 mask, transfer to the facial filter (Table 4)

In Example 3 of Table 4, the same sample used in Examples 1 and 2 was accumulated and sprayed on the outermost filter from 2 to 7 times, and then the mask blocking rate in the above (Example 2) After passing the test, it is the result of testing how much silver (Ag/Silver) with the corresponding antibacterial activity has transferred to the face (inner) filter with the sample. This is an embodiment experiment to confirm that it should not enter the respiratory tract even if it is not given (S6).

As shown in Table 4 above, how much has been transferred to the facial (inner) filter by spraying 2 times (total spray cumulative concentration 50PPM), spraying 5 times (total spray cumulative concentration 75PPM), and spraying 7 times (total spray cumulative concentration 175PPM) As a result of checking (S8), a result in which silver was not detected was obtained. The sample sprayed 2 times / 5 times was transferred to the final facial filter to measure how much residue remains, and the sample sprayed 7 times measured all 4 types of filters as shown in the chart below. The test was measured to the PPB unit by IPA-MS measurement, and it is the result of high precision measurement.

In addition, the manufacturing method according to the present invention described above can be applied to a surface coating process among other printing processes, such as an offset printing process or a silkscreen printing process, in addition to the roller coating method.

According to the antibacterial mask and its manufacturing method according to the present invention, metal ions are coated on the surface of the non-woven fabric surface or the back surface so as to maintain antibacterial power in the mask for yellow dust and prevention, thereby blocking transmission from various microorganisms or bacterial pathogens and sanitation. function can be given.

In addition, methylisocyanolizone (MIT) / methylchloroisothianolizone (CMIT) or benzalkonium chloride ( BKC) and high stability silver (Ag), copper (Cu), and zinc (Zn) are used as micro-grade particles or are ionized. let it be

In addition, the reason for not touching the mask at this point in time when wearing a mask according to the spread of the coronavirus is becoming common is because there is a high possibility that microorganisms or viruses attached to the mask surface can be transferred to the hand and become infected. When a mask having an antibacterial function is used, it is possible to prevent this by minimizing contamination by microorganisms in the face-to-face contact process, and it is possible to maximize the efficiency of wearing the mask.
