Hereinafter, with reference to the accompanying drawings, a preferred embodiment of an antibacterial sticker manufacturing apparatus according to the present invention and an antibacterial sticker manufactured using the same will be described.

First, the antibacterial sticker manufacturing apparatus 1 according to the present invention includes a base film forming unit 10 including a first hopper in which raw materials for manufacturing a base film are stored, and a substrate molded through the base film forming unit 10 An antibacterial raw material supply unit 20 including a second hopper storing an antibacterial material for forming an antibacterial layer on one surface of the film, and one side of the base film after processing the antibacterial material supplied through the antibacterial raw material supply unit 20 An antibacterial layer forming unit 30 for forming an antibacterial layer on the base film, an adhesive layer forming unit 40 for forming an adhesive layer on the other surface of the base film through an adhesive layer forming means, and the adhesive layer forming unit 40 It includes an antiblocking layer forming unit 50 for forming an antiblocking layer on the adhesive layer formed through ) and a release paper laminating unit 60 for laminating release paper for protection on the antiblocking layer, and the antibacterial raw material supply unit 20 An antibacterial sticker that can have a uniform antibacterial power over the entire antibacterial layer by applying the antibacterial substance supplied through the process on one side of the base film and then drying it to form an antibacterial layer so that the antibacterial substance mixed in the antibacterial layer has a uniform distribution. can be manufactured.

Looking at the present invention described above in detail, the base film forming unit 10 is for manufacturing the base film layer A10 constituting the antibacterial sticker, and the first hopper stores raw materials for manufacturing the base film layer A10. (11) and includes a melting means for melting the raw material for forming the base film supplied through the first hopper 11 and a forming means for forming the base film using the melted raw material.

The base film molding unit 10 receives, for example, a polyethylene film (LD-PE, HD-PE, LLD-PE, etc.) as a raw material, melts it, and molds the melted raw material through a molding means to form the substrate. molded into a film

At this time, the thickness of the molded base film is preferably molded to have a thickness of 30 to 35㎛, which is molded to have a thickness of 30㎛ or less, there is a problem of melting or perforation due to high heat during the molding process, and furthermore, the surface is uniform. There is a problem that has not been done. In addition, when molding to a thickness exceeding 35㎛, there is a problem that the consumption of raw materials required for manufacturing increases, which increases manufacturing cost, and the volume and weight of the roll in the process of winding and storing in a roll form after manufacturing is completed. There was a problem with increasing

The melting unit and the forming unit constituting the base film forming unit 10 are used in the process of forming a film, and since the configuration of the melting unit and the forming unit is well known, detailed illustration and description thereof will be omitted.

Meanwhile, the base film forming unit 10 of the present invention may further include a corona discharge treatment unit 12 for corona discharge treatment of the molded base film. The corona discharge improves the wettability (wetting tension) of the base film and simultaneously There is an effect of remarkably improving printability, applicability, lamination, and the like.

That is, since the base film layer A10 is formed using synthetic resin as a raw material, it has low energy and has a chemically inactive surface, and these characteristics make it very difficult to form a printing layer using a printing ink.

Therefore, when forming a printing layer on the surface of the base film of the present invention, the surface of the base film is treated to have a roughness of several tens of nanos through corona discharge to improve hydrophilicity, thereby preventing coating and printing failure. A printing layer is formed using printing ink.

The antibacterial raw material supply unit 20 includes a second hopper 21 storing an antibacterial material for forming an antibacterial layer A20 on one surface of the base film formed through the base film forming unit 10. As a result, the second hopper 21 is loaded with raw materials and discharges the input raw materials in a certain amount.

At this time, the second hopper 21 is further provided with an antibacterial substance input means 22 into which an antibacterial substance for forming an antibacterial layer is injected and an agitation means 23 for agitating the antibacterial substance injected into the second hopper 21 However, the antibacterial substance input means 22 is for introducing the antibacterial substance into the storage space side of the second hopper 21 while having a uniform distribution.

As shown in FIG. 3, the antibacterial material inlet 22 is rotatably disposed in the antibacterial material inlet 221 formed on one side of the second hopper 21 and the antibacterial material inlet 221, and is rotatably disposed in the longitudinal direction. A rotating body 222 having a passage 223 through which the antibacterial material moves in the center thereof is connected through the rotating body 222 and the power transmission body 224 and operated by the applied power and signal while the rotating body A rotation drive motor 225 for rotating the 222, a cap 226 for opening and closing one end of the longitudinal direction of the rotating body 222, and a diffuser rotatably disposed at the other end of the longitudinal direction of the rotating body 222. Includes ball 227.

The antibacterial material inlet 221 is formed to communicate the inside and outside of the second hopper 21 at either the top or outside of the second hopper 21, and rotates the rotating body 222 on the inner surface. A rotation bearing (B) for supporting is disposed.

The rotating body 222 extends in the longitudinal direction and is formed in the form of an empty tubular body to form a passage 223 through which the antibacterial substance moves therein, and is rotatably disposed in the antibacterial substance inlet 221 .

Here, the rotating body 222 is formed so that one end disposed inside the second hopper 21 has a relatively smaller diameter than the outer diameter of the passage 223, so that a diffusion ball 227 described later is formed. It prevents the diffusion balls 227 from falling into the second hopper 21, that is, toward the storage space.

Next, on the other side of the rotating body 222 disposed outside the second hopper 21, an assembly 222a coupled to a power transmission body 224 for receiving power from the rotary driving motor 225 is disposed.

At this time, the combination body 222a is changed to correspond to the configuration of the power transmission body 224, for example, when the power transmission body 224 is formed of an annular belt, it is disposed surrounding the outer circumferential surface of the rotating body 222 It may be made of an annular ring provided with a plurality of protrusions protruding at regular intervals to prevent slipping of the belt in contact, and when the power transmission body 224 is made of a chain, the coupling body 222a is made of a gear with which the chain meshes. can

The rotary driving motor 225 is connected to the rotating body 222 and the power transmission body 224 while operating by applied power and signals to rotate the rotating body 222 .

Since the operation relationship and power transfer process of the rotary driving motor 225 are well known, detailed descriptions and illustrations will be omitted.

The cap 226 opens and closes one end of the longitudinal direction of the rotating body 222, and opens or closes the passage 223 of the rotating body 222.

The diffusion ball 227 is rotatably disposed in the passage of the rotating body 222, and when the rotating body 222 rotates through the power transmitted from the rotation driving motor 225, the rotating body 222 The antibacterial substance drawn into the passage 223 is discharged to the storage space side of the second hopper 21 while freely rotating inside.

The antibacterial substance discharged from the passage 223 through the diffusion ball 227 increases the discharge distance and widens the discharge range, and through this, the antibacterial substance injected into the second hopper 21 Avoid focusing on only a few.

To explain this in more detail, when raw materials are injected into a general hopper, the degree of distribution of the injected raw materials varies depending on the form of the raw materials. By scattering in the storage space as a whole, it can have a wide emission range. On the other hand, when a plurality of raw materials are mixed in a gel form, the specific gravity is high, so the discharge location and range are inevitably limited, and raw materials with a small specific gravity in the raw materials mixed in a gel form move to the edge side and have a relatively heavy specific gravity. There was a problem in that the overall distribution was different because the raw materials moved downward and the raw materials were scattered according to their respective specific gravity.

In the present invention, the antibacterial substance for forming the antibacterial layer is a combination of titanium dioxide (TiO2) and hollow silica (SiO2) in an adhesive, and since titanium dioxide and hollow silica are blended in an adhesive, it is in a gel form. It is put into the second hopper (21).

Therefore, the above-described problem may occur, and thus, there is a problem in that the antibacterial effect of the antibacterial layer formed on one surface of the base film is different from each other.

In order to solve this problem, in the present invention, the diffusion ball 227 is placed in the passage 223 formed in the rotation body 222 to increase the distance at which the antibacterial substance transferred through the passage 223 of the rotation body 222 is discharged. and by widening the discharge range, each component constituting the antibacterial material can be uniformly distributed.

The diffusion ball 227 for this purpose is formed in a spherical shape and is disposed in the passage 223. When the rotating body 222 is rotated by the rotation drive motor 225, the diffusion ball 227 is rotated by the rotating body 222. ) is rotated by friction with the inner surface of the

At this time, the outer circumferential surface of the diffusion ball 227 is formed in an intaglio shape, and a discharge path 228 formed in a form in which a pair cross each other is provided so that the diffusion ball 227 closes the end of the rotating body 222. Even in one state, the antibacterial substance is injected into the second hopper 21 through the discharge passage 228 .

Here, as the diffusion ball 227 rotates by friction with the rotating body, the discharge distance of the antibacterial substance discharged through the discharge path 228 increases and the discharge range widens, so that By spreading widely, a relatively evenly distributed ratio is achieved compared to continuous input to one side.

In addition, the discharge path 228 formed in the diffusion ball 227 can discharge the antibacterial material transferred through the passage 223 to the second hopper 21 even when the rotating body 222 does not rotate. Through this, when the antibacterial substance is in a powder form rather than a gel form, the antibacterial substance can be injected into the second hopper without rotating the rotating body.

The stirring means 23 is rotatably disposed inside the second hopper 21 to agitate the injected antibacterial material so that a plurality of raw materials constituting the antibacterial material are mutually mixed, and at the same time the antibacterial material is cured inside the second hopper prevent becoming

The agitation means 23 includes an agitation shaft and a plurality of impellers arranged radially on the agitation shaft, and the agitation shaft rotates by receiving power from an agitation drive motor operated by applied power and signals.

The configuration and operational relationship of the agitating means 23 is a well-known configuration used to prevent mixing and curing of multiple raw materials, and detailed illustration and description thereof will be omitted.

On the other hand, the antibacterial material is a combination of titanium dioxide (TiO2) and hollow silica (SiO2) in the adhesive, but the titanium dioxide is mixed in the range of 5 to 15 parts by weight with respect to 100 parts by weight of the anatase type titanium dioxide adhesive, the hollow Type silica having a particle size of 1 to 3 μm is mixed in the range of 5 to 15 parts by weight based on 100 parts by weight of the adhesive, and the titanium dioxide and hollow silica are mixed in a weight ratio of 1: 1 to 2: 1.

The titanium dioxide exhibits antibacterial performance, and in particular, exhibits photocatalytic activity by ultraviolet irradiation to decompose various organic substances formed on the surface. It is preferable to use anatase-type titanium dioxide as the titanium dioxide.

In addition, the antibacterial effect is improved by mixing hollow silica together with the titanium dioxide as the antibacterial material. The hollow silica can cause diffuse reflection when a micrometer-sized hollow is formed, and when combined with the titanium dioxide, the contact amount of ultraviolet rays can be increased, thereby improving the antibacterial performance of the antibacterial substance applied to the base film. do.

The hollow silica has a particle size of 1 to 3 μm, and can be prepared by applying the manufacturing method according to the following examples.

Polystyrene beads are used to prepare hollow silica. That is, polystyrene beads (Spherotech) with a size of 1.8 μm are dispersed in distilled water to prepare a colloidal solution of polystyrene beads, and then tetraorthosilicate (OCI) and hydrochloric acid (HC1, 37%, Sigma) as a catalyst are added thereto. Add. Ammonia (ammonium hydroxide, 25%, OCI) was added dropwise to adjust the pH, heated to 80° C., and reacted for 2 hours to apply silica to the surface of the polystyrene beads. Thereafter, the solid content is recovered, dispersed in ethanol-water solvent, put into a hydrothermal reactor, hydrothermal reaction is performed for 10 hours, the polystyrene inside is decomposed, washed and dried, and the hollow silica having a D50 dl of 2.5 μm and a hollow size of 1.5 μm is decomposed. Particles were prepared.

The titanium dioxide and the hollow silica may be mixed in the range of 5 to 15 parts by weight, respectively, based on 100 parts by weight of the adhesive. That is, the combined weight of titanium dioxide and hollow silica may be mixed in the range of 10 to 30 parts by weight based on 100 parts by weight of the adhesive. When the content of titanium dioxide and hollow silica is mixed to less than 10 parts by weight, antibacterial performance cannot be sufficiently obtained, and when it exceeds 30 parts by weight, there is a problem in that the adhesive strength is lowered, so it should be contained within the above range.

In addition, the titanium dioxide and the hollow silica are preferably blended in a weight ratio of 1:1 to 2:1. That is, the photocatalytic effect can be further improved by mixing the hollow silica in proportion to the content of the titanium dioxide.

In particular, if the content of the hollow silica is too small, sufficient antibacterial effect cannot be obtained when applied to the antibacterial sticker of the present invention, and even if it is too large, the content of titanium dioxide as a photocatalyst is reduced and the antibacterial effect may be reduced.

The antibacterial layer forming unit 30 melts the antibacterial material supplied through the antimicrobial raw material supply unit 20 to form an antibacterial material in a gel state into a liquid, and then through a spray nozzle to form a base film layer ( A10), and drying the base film layer (A10) coated with an antibacterial material through a drying means to form an antibacterial layer (A20).

The antibacterial layer forming unit 30 includes a melting means for melting the antibacterial material, a coating means for applying the molten antibacterial material on one surface of the base film layer A10, and a drying means for drying the base film coated with the antibacterial material. Including, but these melting means, coating means and drying means structures are known to be used in the process of forming a sticker or film, and detailed illustration and description thereof will be omitted.

The adhesive layer forming unit 40 is formed on the other surface of the base film layer A10 through an adhesive layer forming means, wherein the adhesive layer forming means is any one of a rolling device using a roller and a spraying device using a spray nozzle. It can be made of one, and the adhesive layer is an acrylic adhesive. This acrylic adhesive is capable of temporary adhesive rather than permanent adhesive, and since this acrylic adhesive is known, the detailed types of additives and the composition ratio of additives are omitted.

The antiblocking layer forming unit 50 forms an antiblocking layer on the adhesive layer formed through the adhesive layer forming unit 40, and the antiblocking layer is attached to the adhesive layer by minimizing the slip phenomenon of the adhesive layer. The release paper is prevented from being arbitrarily separated.

This anti-blocking layer is formed by spraying mineral powder on the adhesive layer composed of acrylic pressure-sensitive adhesive, and it is preferable to use zeolite, which is a porous mineral, as the mineral powder. Experiments were conducted according to the type of zeolite, assuming that the mineral powder could improve the adhesive force by absorbing some of the acrylic adhesive component.

Experimentally, it has been shown that an antiblocking layer can be stably formed when a zeolite having a MOR (mordenite) crystal structure is used. The pore volume of the zeolite of the MOR crystal structure is 0.27 to 0.28 mL/g, when the zeolite (zeolite Y) of the FAU crystal structure having a larger pore volume and pore size is used, or the MFI crystal having a smaller pore volume and pore size It was confirmed that the stability of the antiblocking layer was formed more stably than when the structured zeolite (ZSM-5) was used.

This is because when measuring the weight loss by spraying 40 g of zeolite powder per unit area (1m2) and applying vibration to the same acrylic adhesive layer, the loss amount is less than 5% when using the zeolite of the MOR crystal structure, whereas the zeolite of the FAU crystal structure It was found that the loss amount increased up to 12% in the case used, and the loss amount was up to 10% even when the zeolite with the MFI crystal structure was used.

All of the zeolite powders are pulverized to an average of 80 mesh, and the size of the powder also affects, but it is thought that the effect of the type of zeolite is greater than this.

The antiblocking layer made as described above maintains the adhesive strength of the adhesive layer, so that the protective film can maintain a stable adhesive state.

The release paper laminating unit 60 adheres the release paper A50 to the adhesive layer A30 in order to protect the adhesive layer A30 on which the antiblocking layer A40 is formed, through a laminating roller means including a laminating roller. It is done.

The lamination roller means including these lamination rollers is a wet lamination method (lamination treatment (a method of applying an adhesive dissolved in water or a solvent and then immediately overlapping) or a dry lamination treatment (drying after applying an adhesive) The wet lamination method or the dry lamination method and the structure of the lamination roller means for this method are used, so detailed description and illustration are omitted. let it do

Meanwhile, a cutting unit 70 including a cutter for cutting the antibacterial sticker to which the release paper is laminated into various shapes may be further provided through the release paper laminating unit 60, and the cutting unit 70 is used to cut the antibacterial sticker. For example, when the antibacterial sticker is cut to a certain length, it is configured to cut the antibacterial sticker through a lifting operation after being placed on the top or bottom, or as another example, the antibacterial sticker is cut to have a specific shape. In the case of arranging a plate-shaped cutter having a specific shape, it may be configured to cut the antibacterial sticker in a perforated form.

As shown in FIG. 5, the antibacterial sticker (A1) manufactured through the antibacterial sticker manufacturing apparatus 1 made as described above has a base film layer (A10) and an adhesive on one side of the base film layer (A10). Titanium dioxide (TiO2) and hollow silica (SiO2) are mixed, but the titanium dioxide is mixed with anatase-type titanium dioxide in the range of 5 to 15 parts by weight based on 100 parts by weight of the adhesive, and the hollow silica has a particle size 1 to 3 μm is mixed in the range of 5 to 15 parts by weight based on 100 parts by weight of the adhesive, and the titanium dioxide and hollow silica are mixed in a weight ratio of 1: 1 to 2: 1. The layer (A20), the adhesive layer (A30) formed on the other surface of the base film layer (A10), the antiblocking layer (A40) applied to the adhesive layer (A30), and the adhesive layer (A30) are separated. It includes a release paper (A50) that is possibly adhered.

At this time, since the antibacterial substance constituting the antimicrobial layer (A20) is uniformly applied throughout, the antibacterial effect can be expected to be uniform throughout the antimicrobial layer (A20), and the adhesive layer (A30) is protected through the antiblocking layer (A40). At the same time, the release paper (A50) is prevented from being arbitrarily separated from the adhesive layer (A30) to prevent the release paper (A50) from being separated during storage or movement, thereby improving use safety.

In addition, a high antibacterial effect can be expected by diffusely reflecting ultraviolet light or visible light incident through the hollow silica constituting the antimicrobial material to activate a photocatalyst of titanium dioxide.
