Description

Droplet-blocking mask

Technical Field

The present invention relates to a droplet blocking mask, and more particularly, to a droplet blocking mask having excellent droplet blocking properties and high antiviral and antibacterial properties.

Background

Recently, the risk of diseases has increased with the emergence of highly contagious viruses, and thus, the demand for personal hygiene and antibacterial is sharply increasing in public places in which there is much contact with others. In addition, in order to prevent diseases transmitted by droplets, the demand for droplet blocking masks is continuously increasing.

Although various masks have been developed to prevent respiratory infectious diseases, conventional masks are generally made of cotton fabrics, non-woven fabrics, or the like, and have no antibacterial properties, and thus have a problem that they are easily contaminated with bacteria or viruses.

In addition, in order to effectively prevent respiratory infectious diseases, droplets secreted through human-to-human interaction, coughing, or the like need to be blocked, but conventional masks have a problem in that droplets are absorbed by the mask or permeate into the mask because it is difficult to completely block droplets from the outside.

Disclosure of Invention

In order to solve the above problems, an object of the present invention is to provide a droplet barrier mask which has excellent antibacterial properties, antiviral properties, and droplet barrier properties and can be used for a long time by replacing a droplet barrier portion.

In order to achieve the above technical object, the present invention provides a droplet blocking mask, comprising: a mask body for providing a face receiving space; a mask band part extending from both side surfaces of the mask body part; and a splash barrier detachably coupled to an outer surface of the mask body, the splash barrier including a polymer resin and an antimicrobial agent dispersed in the polymer resin, the antimicrobial agent including copper, zinc oxide, and zeolite (zeolite).

The droplet barrier mask of the present invention has excellent antibacterial properties, antiviral properties, and droplet barrier properties, and can be used for a long period of time by replacing the droplet barrier section.

In one embodiment of the present invention, the mask body 10 and the mask band 11 form the entire appearance of the mist barrier mask 100. In this case, unlike the conventional mask including the mask body and the mask band, the droplet isolation mask 100 of the present invention further includes the droplet isolation portion 20 including the antibacterial agent, so that not only the penetration of droplets from the outside of the mask to the inside of the mask body 10 can be isolated, but also bacteria and viruses can be effectively isolated.

The present invention relates to a splash-proof mask 100 including a mask body 10 and a mask band 11. According to an example, as shown in fig. 1, the mask band 11 is extended from both sides of the mask body and is integrally formed with the mask body, or as shown in fig. 4, the wearing part 41 is coupled to the coupling holes 42 provided in the mask body and the mist barrier 20 via the coupling member 43.

Further, the zinc oxide can impart not only excellent antibacterial properties but also deodorizing properties and Ultraviolet (UV) blocking properties to the mist barrier section 20 and impart ultra-water repellency thereto. In particular, in the present invention, zinc oxide can further provide antibacterial power against gram-negative bacteria.

When the zinc oxide is in a nano size, the antibacterial activity can be maximized by increasing the affinity with bacteria and the like. For example, the average diameter of the zinc oxide may be about 8nm to 100nm, preferably about 40nm to 80nm, and more preferably about 60nm to 75 nm.

The content of the above zinc oxide is not particularly limited, and according to one example, may be about 0.2 to 1 weight percent, preferably 0.2 to 0.3 weight percent, based on the total weight of the corresponding antibacterial composition. According to another example, the ratio (mixing ratio) of zinc oxide to zeolite may be 10:90 to 30:70 by weight, preferably 10:90 to 20:80 by weight, based on the total weight of zinc oxide to zeolite.

And, specifically, the above zeolite is an alkali metal and/or alkali metal-plated aluminum silicate (aluminum silicate) hydrate having (Si, Al) O as one basic unit₄Tetrahedra share oxygen with other tetrahedra to form a three-dimensional network. The zeolite can impart antibacterial properties to the splash barrier 20.

The droplet-blocking section 20 formed of the antibacterial composition has an antibacterial activity value of 2 or more against gram-positive bacteria and gram-negative bacteria, respectively, and an antiviral activity value of 3 or more against a new coronavirus.

The above-mentioned antibacterial composition can be prepared by a method generally used in the art to which the present invention pertains. For example, the antibacterial composition can be prepared by mixing and stirring an antibacterial agent comprising a polymer resin, copper, zinc oxide and zeolite and selective additives at normal temperature or at an appropriate temperature using a mixing device such as a ball mill, a bead mill, a three-roll (3roll mill) basket (basketmill) mill, a nano mill (dyno mill), a planetary mill (planetary mill) or the like.

The splash barrier 20 of the present invention can be manufactured by a method generally used in the art to which the present invention pertains, and is not limited to the following manufacturing method. May be performed by modifying or selectively blending the steps of the respective processes according to the requirements.

According to one example, the splash barrier 20 can be produced by a single-layer blow coextrusion method after mixing (compounding) by a twin-screw mixer (twin screw mixer).

According to an embodiment of the present invention, at least one surface of the droplet barrier 20 may be a matt (matt) surface. The matt surface may be formed by a matt (matt) process, thereby imparting a unique feel or appearance to the splash barrier 20. According to one example, the droplet blocking section 20 may include a surface concave-convex pattern section.

According to an embodiment of the present invention, the droplet-blocking portion 20 may include an opening formed below the droplet-blocking portion 20 And the end is used for ventilation. The opening part is arranged at the lower end of the mask, so that the breathing can be smooth even if the mask is worn for a long time. In this case, the opening is located in the lower jaw of the user to block the spray. According to an example, the size of the opening is 3cm²To 15cm²Preferably 8cm²To 12cm²。

According to an example of the present invention, the splash guard 20 is detachably coupled to the outer peripheral surface of the mask body 10. In this case, the entrainment barrier 20 can be separated from the outer face of the mask body 10 by a fastening member, and therefore, when the entrainment barrier 20 is contaminated, the mask body 10 can be reused by merely replacing the entrainment barrier 20 while keeping the same.

In the present invention, the material used as the fastening member in the mask for preventing splash is not particularly limited, and a fastening member that is generally used in the art to which the present invention pertains and that can be coupled and separated may be used. For example, the fastening member may be one selected from the group consisting of a button insertion hole, a snap, a fastener tape, and a magnet. As shown in fig. 3, according to an embodiment of the present invention, the droplet blocking part 20 and the mask body part 10 may be coupled or separated by the first snap fastener member 30 provided at the droplet blocking part 20 and the second snap fastener member 30' provided at the mask body part 10.

According to an example of the present invention, the mask body 10 and the splash-proof part 20 may have a protruding shape corresponding to the protruding shape of the face of the user. In order to manufacture the mask body 10 and the droplet shielding part 20 having the above-described shapes, a high-frequency sealing (sealing) process may be performed. When manufacturing the plastic mask having the above shape, although the sticker is used conventionally, the sticker may be detached when the mask is washed or used for a long time.

In contrast, the present invention utilizes a high frequency sealing (sealing) process when manufacturing the mask body 10 and the droplet blocking member 20. In one embodiment of the present invention, the left and right side portions of the mask body 10 and the mist barrier 20 are formed in a left-right symmetrical shape, and both side end portions of the left and right side portions are attached by a high frequency sealing process, thereby manufacturing a mask having a protruding shape. The mask manufactured through the high frequency sealing process can maintain the three-dimensional structure of the mask even when washed or used for a long time, and thus can be used semi-permanently.

In the present description, the mask body 10 and the mist barrier 20 are exemplified to have a single-layer structure, but the present invention is not limited thereto. In addition to the structures exemplified in the present specification, other structures may be included, for example, the mask body 10 and the entrainment separator 20 may have two or more layers, respectively.

The present invention will be described in further detail below with reference to examples. However, the following examples are merely illustrative of the present invention and do not limit the scope of the present invention.

Evaluation example 1 evaluation of flying foam Barrier Property

In order to measure the spray barrier properties of the masks manufactured in examples and comparative examples, the moisture reflectance (%), moisture absorption (%) and moisture permeability (%) were measured by the following methods.

The mask manufactured by the examples or comparative examples was worn on a human body model. As shown in FIG. 5, after a spray gun was set at a position 30cm from the phantom, 50g of water at 30 ℃ was sprayed for 60 seconds. In this case, the spray gun had a nozzle diameter of 1.8mm and a spray pressure of 3kgf/cm²The spray angle was 45 degrees. After 60 seconds passed after the completion of the spraying, the moisture reflectance (%), the moisture absorption (%) and the moisture permeability (%) were measured, and the results are shown in table 1 below. In this case, the sum of the above values should be 100%, but it is estimated from the moisture dispersion (%) that the evaporation in the air is causedDosage, etc., within 1% -5%.

1. Water content reflectance (%)

The moisture reflectance means a degree to which moisture sprayed from the spray gun is reflected again to the outside of the mask. The moisture reflectance may be calculated according to the following equation 1.

Equation 1

In this case, since the masks of comparative examples 1 to 5 have no outer skin, only the weight of water falling under the manikin was measured.

2. Water absorption rate (%)

The moisture absorption rate means a degree of absorption of moisture sprayed from the spray gun by the inner skin of the mask. The moisture absorption rate can be calculated according to the following equation 2.

Equation 2

3. Moisture permeability (%)

The moisture permeability refers to the degree of penetration of moisture sprayed from a spray gun into the interior of the mannequin. The moisture permeability can be calculated according to the following formula 3.

Equation 3

TABLE 1

	Water content reflectance (%)	Water absorption rate (%)	Water permeability (%)
				Examples	93	4	0
Comparative example 1	6	89	4

				Comparative example 4	17	82	0
Comparative example 5	30	68	0
				Comparative example 6	30	70	0
Comparative example 7	17	88	0

As shown in table 1 above, it was confirmed that the mask of the present invention has a moisture reflectance as high as 93%, a moisture absorptance as low as 4%, and a moisture permeability of 0% (example 1). In contrast, it was confirmed that the normal mask had a moisture reflectance of 30% or less and a moisture absorptance of 68% or more (comparative examples 1 to 5). Further, it was confirmed that the double mask made by combining the two masks had a moisture reflectance of 30% or less and a moisture absorptance of 70% or more (comparative examples 6 and 7).

As described above, it was confirmed that the mask of the present invention has excellent droplet barrier properties compared to the normal mask and the double mask of the comparative examples, since the mask further includes the droplet barrier portion including the polymer resin.
