Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of manufacturing an adhesive mask,

The present invention relates to a method of manufacturing an adhesive mask and a mask therefor. More specifically, the present invention relates to a method of manufacturing a pressure-sensitive mask which comprises a filter body having a space portion having a face-following property and having a good filtering function of fine particles such as dust, And the filter body is sandwiched between an outer skin fabric having heat-resistant formation and an inner skin fabric having a thermoplastic hot-melt resin coating layer formed thereon. The mask molded body is molded and cut into a mask molded body molding die and flapped symmetrically on both sides of the filter body, a mask body provided with a flap, and a pressure-sensitive adhesive molded article obtained by adhering an olefin resin sheet, EVA, or an adhesive gel sheet of a silicone resin on the inside of the inner surface of the mask body, Method and a mask thereof.

Unlike the conventional mask, the mask produced by the above method is a thermoformed mask formed by a thermoforming mold. The mask has a specificity and is free from a string for binding to the ear, and is adhered and fixed to the face by a sticky- It is an adhesive mask.

Further, since the adhesive molded article adhered to the inner surface of the mask has an excellent adhesive force, it can be used at least thirty times, and its adhesion is stronger than other conventional masks. Therefore, It is possible to greatly increase the dustproof rate and to easily attach and detach, which is convenient to use.

In recent years, along with rapid industrial development, air quality has been seriously deteriorated due to various harmful gases such as soot generated by the use of fossil fuels, and combustion dust generated by the use of dust and coal, especially in China A mask having a function is desperately required in a situation where it is in a work environment.

With this in mind, in addition to research on masks in Korea, literature and products related to various types of mask are being released.

The technical contents of the conventional masks are disclosed in detail in Korean Patent Publication No. 10-2013-1343880, and the description of the mask is written on the face of the user to shield the face portion. A horizontal folding part 120 provided on both sides of the face closure part 110 and allowing the both sides of the face closure part 110 to be fixed in a state of being folded with a predetermined degree about the horizontal axis C, Wherein the horizontal folded portion 120 includes a first Velcro 121a disposed at an upper portion of the face closure 110 and a second Velcro 122a engageable and disengageable with the first Velcro 121a, The first Velcro 121a and the second Velcro 122a may each be a mask formed by extending a predetermined length in the longitudinal direction.

Such a mask can form a space inside the mask by forming a folded portion in the face closure through the horizontal folded portion, which makes it easy to breathe and communicate, is comfortable to wear and can prevent the saliva from being stuck, The first velcro and the second velcro are folded to form a large air passage at the folded portion, so that the contaminated air from the outside is directly sucked without passing through the filtration layer, so that an excellent dustproof rate can not be expected.

As another conventional technique, the technical content of the mask is disclosed in the Korean Patent Laid-Open Publication No. 10-2012-54176. The technical content of the mask is a mask face which is made of a double- (40, 40a) are formed on the front and rear surfaces of the mask surface (20), which is composed of the mask part (20) and the hook part (30) on both sides of the mask surface (20) And a directional material such as a hub or a pine needle is inserted into the rear housing part 40a. Such a mask may have mental fatigue and stability due to the filtering function and directional material of the male. However, since the feeling of wearing is not good and the adhesion feeling is poor, the amount of air sucked directly into the mask is increased, .

As another prior art, a patent document (registration number: 2013-1232333) discloses a technical content of a multifunction mask.

The present invention relates to an image forming apparatus having an air inlet hole formed at an upper portion thereof, an upper mask including a lens portion having a protective lens formed therein and a nose receiving portion for receiving a nose sucking air introduced through the air inlet groove, A lower check valve is formed and a discharge check valve for discharging air is formed and an auxiliary connection part for supplying air to breathe through the mouth is formed. An air supply pipe installed above the upper mask and passing through the air inflow hole is constituted An air supply member for supplying air to the air inlet hole, the air supply member being composed of an air main body having threads formed on both outer circumferential surfaces and a supply check valve formed at both side ends of the air main body, So that the outside air can be purified and supplied to the inside of the upper mask A filter member for purifying the outside air is fixedly installed at one end of the purifier pipe and a purifier filter member having a connection gerber is provided at the other end of the purifier filter unit to be connected to the air supply member, Gt; mask < / RTI > Such a functional mask can be said to be a mask which can greatly increase the vibration proof rate by blocking the outside air and the internal space significantly, but it is said that the mask is too complicated to constitute, and the wearer feels uncomfortable, .

In the prior art, a mask for a sunshade having a function of intercepting yellow dust is provided in a domestic patent publication (registration number: 2005-474500). The mask has a ventilation hole formed in front of the mask and a ventilation hole formed in the cover. The folded inner side is stitched to the upper part of the front bezel on both sides of the ventilation hole so that the lid itself is spaced a certain distance from the surface of the mask so as to be stably placed on the nose of the consumer, the filter member is sewed on the inner side of the lid, It can be said to have a sunshade in place. A mask having such a structure can be a mask which can not directly receive the air, and can not be expected to have a dust-proofing purification rate because a considerable amount of outside air can directly enter the respirator without passing through the filter body.

According to the present invention, it is possible to improve the filtration function by providing a uniform space between the mask and the face, thereby increasing the uniform suction pressure and discharge pressure of the air to the filter body, The present invention aims to provide a method of manufacturing a self-adhesive mask without blocking the outside air and without an earring strap by using a sticky gel sheet of a thermoplastic resin by maximizing the dustproof rate by preventing the inflow of air which has not been passed through the filter body. .

The film is thermoformed with a female mold and a male mold having a suction function, A mask body having flaps formed on both sides thereof, and a pressure-sensitive adhesive cut sheet obtained by cutting an adhesive sheet of polyolefin, EVA or silicone water on the inner surface of the mask body is bonded along the inner side of the inner surface of the mask inner surface, The object of the present invention can be achieved.

The pressure-sensitive mask according to the present invention is formed in such a manner that the fabric of the mask comes in close contact with the nose and the nose as it is breathing like a conventional mask, and the wearer feels a frustration. On the other hand, Because it is easy to get in and out of the body, it does not feel tight. Also, the adhesive cut molding adhered along the inner side of the inner surface of the mask and the elastic filter material forming the boundary line tightly adhere to the face, Because it can not enter the polluted air, it can maximize polluted air purification filtration rate, and it can be said that it is a clean, easy-to-use adhesive mask without earrings.

The present invention relates to a manufacturing method of a face-to-face type mask which prevents entry of outside air and has no earring strap, and a mask thereof. First,

A step for forming a filter body by thermoforming into a mold for molding a filter body forming a space portion having a face followability with a thermoforming member having excellent fine particle filtering function such as dust, dust, dust, dust, etc., A two-step process of molding a mask molded body with a mask molded body mold by inserting a filter body between the endothelial woven fabric formed with a thin film coating layer of a thermoplastic hot-melt resin, a three-step process of cutting the mask molded body by punching the mask molded body with a cutting edge, A four-step process of cutting a sticky gel sheet to obtain a pressure-sensitive adhesive molded article, and a five-step process of adhering an adhesive molding along the inner side of the edge to the inner side of the mask body.

The molding method of the filter body 1 in the one-step process will be described. The molding method of the filtration body 1 is the same as that of the first embodiment except that the filament sachet 2A, the polyester nonwoven fabric 1 by using the female mold 3A and the male mold 3B of the filtration molding die 3 by using a thermoforming member selected from a nonwoven fabric 2B and a mixed yarn nonwoven fabric 2C, (1) can be obtained.

In the above description, the double sick cloth 2A has the polyester nitrile fabric 2A1 of the upper layer and the polyester nitrile fabric 2A2 of the lower layer formed parallel to each other at a predetermined interval (3 to 4 mm) The polyester nonwoven fabric 2B is a nonwoven fabric composed of a polyester fiber 2B1 and the mixed nonwoven fabric 2C is a polyester fiber yarn 2C1. The nonwoven fabric may be a homogeneous plain nonwoven fabric obtained by forming a mixed yarn of 90 to 95% by weight and acrylic fiber yarn (2C2) or 5 to 10% by weight of polypropylene fiber yarn (2C3).

The filtration body molding method using the thermoformed member 2 and the filter mold forming mold 3 is selected from the double sickle sheet 2A, the polyester nonwoven fabric 2B and the mixed nonwoven fabric 2C as shown in Fig. 2 One thermoformed member 2 is placed on the female mold flat plate 3A1 so as to cover the mouth of the female mold 3A and then the mold fixing plate 3B1 of the male mold 3B is lowered to be in close contact with the female mold 3A, The thermoplastic resin composition of the present invention is thermoformed for 5 to 10 seconds while maintaining the temperature of the softening point and the melting point of the thermoformed article of the present invention.

When the double sickle sachet 2A or the polyester nonwoven fabric 2B is used as a member for forming a filter body, the temperature of the mold should be maintained at 200 to 240 DEG C. When the mixed nonwoven fabric is used, the temperature range of the mold is 160 DEG C- The molding temperature can be largely divided by maintaining 200 ° C.

When the male mold 3B of the present invention filter mold 3 is completely adhered to the female mold 3A, a certain gap is maintained between the two molds. At the entrance of the female mold 3A, The narrower the gap is, the wider the gap becomes. In the case of a molded filter, the center of the filter becomes thickest, and the filter becomes thinner at the top and becomes thinner at the edge of the filter.

In other words, the density is low in the thick part and high in the thin part.

The structure of the mold and the state of the molded article are to ensure excellent breathability at the mouth and nostril positions of the mask.

The method for producing the mask molded body 4 in the two-step process as the filter body 1 obtained in the above-described first step process is a method in which the double sickle sheet 2A, the polyester nonwoven fabric 2B and the mixed nonwoven fabric 2C (1), a sheath fabric sheet (5), and an endocardial fabric sheet (6) on which a thin film coating layer (6A) of an acrylic hot melt or polyurethane hot melt resin is formed as a member (2) The mask molded body 4 can be obtained by thermoforming the molded body 4 with the mask mold 4.

As shown in Fig. 3, in the state where the temperature is maintained at 120 캜 to 150 캜, The outer cloth fabric 5 is placed on the flat plate surface 7A1 formed on the upper end of the mold 7A so as to cover the entrance of the female mold and then the filter body 1 is fixed on the outer surface of the outer cloth fabric 5, And the thin plate coating layer of the thermoplastic hot-melt resin is placed on the lower plate 7B1. Then, the plate 7B1 of the male die 7B is lowered to fix the plate, the male die 7B is moved upward, The suction chamber 7A3 is depressurized in a tightly closed state and thermoformed for 5 to 10 seconds while being sucked through the suction holes 7A2 and then extracted upward in the order of the male mold 7B and the molded material fixing plate 7B1, 4).

In the above description, the thermoplastic hot-melt resin may be a single thermoplastic hot-melt resin selected from an acrylic hot-melt resin and a polyurethane hot-melt resin.

The molded part configuration of the female die 7A and the male die 7B of the molding die 7 of the mask molded body 4 is the same as that of the molded part of the filter die forming die 3, The mold 7 is different from the structure in which the suction hole 7A2 and the suction chamber 7A3 connected to the motor are provided under the female mold 7A.

That is, the configuration of the molding part formed when the female mold 7A and the male mold 7B of the mask molded body forming mold 7 are in close contact with each other maintains a constant gap between the two molds. At the entrance of the female mold 7A As the gap formed between the female mold and the male mold becomes narrower and the lower the mold is, the larger the gap width gradually becomes. The constitution of such a molded part has an object to ensure excellent air permeability in a mask molded article in which the mouth and nose portions of the mask molded article are located.

In addition, the molding temperature (120 DEG C to 150 DEG C) range of the mold and the suction operation by the suction hole 7A2 play an important role in securing the air holes.

The thin film coating layer 6A1 of the acrylic hot melt resin and the thin film coating layer 6A2 of the urethane hot melt resin are easily melted in the temperature range of 120 to 150 ° C to be a melt. At this time, when the suction chamber 7A3 is depressurized, 7A2), a strong suction force acts on the molded body, so that the molten membrane of the hot-melt resin coating layer 6A formed on the endodnestic fabric 6 ruptures and penetrates into the filtration body 1 in the form of fine fibers, The hotmelt thin film is ruptured and broken and penetrates into the filter body in the form of a thin fiber to bind the endodnextural fabric 6 and the filter body 1, thereby securing the vent hole.

When the thermoformed mask molded body 4 is cut in the three-step process, the mask body 8 can be obtained. The mask body cut-out blade is a cut-forming blade that coincides with the edge line of the formed mask body. ), The cut mask body 8 can be obtained.
