Description

Masking tape for mosaic art play {MASKING TAPE FOR MOSAIC ART PLAY}

The present invention relates to a masking tape for art play in a mosaic method, and in more detail, a user, such as a child, can conveniently open and paste a completed mosaic picture or image without the help of a parent. It's about masking tape that can help you do what you can.

Masking tape is widely used for attaching exposed wires or sharp edges to construction walls, ceilings, and furniture, and is also used for reforming or interior decoration.

In the early 1900s, cellophane was used to package products, but even if they were packaged with cellophane, there were many problems that the product, especially food, became wet or spoiled. To solve this problem, 3M has developed a tape using cellulose as its main material, which can be said to be the original masking tape.

As mentioned earlier, masking tape was originally used for cleaner painting by attaching it to areas that should not be applied when painting on furniture or walls, but nowadays, masking tapes with various colors, patterns, and designs have been produced. It is also widely used to add design elements such as color bands.

Various technologies for such masking tapes have been disclosed, and the masking tape for interior board installation, which is Korean Patent No. 2021788, forms an upper adhesive layer on the upper surface of the long tape that is maintained at a constant width and release paper on the upper surface of the adhesive layer. It adheres, and a lower adhesive layer is formed on the side of the tape, and the section division center line is formed long on the center line in the longitudinal direction from the upper surface of the tape, and the division section auxiliary lines maintained at regular intervals are aligned on both sides of the section division center line. And forming an interval dividing line at regular intervals between the parallel divisional subsidiary lines and the divisional subsidiary lines, and forming a color band between the section divisional subsidiary lines and the section subsidiary lines; Repeating formation of the tape by maintaining a horizontal spacing center line at a constant distance d1 so as to intersect the section segment center line on the upper surface of the tape; By forming an interval division auxiliary line at regular intervals between the interval division center line and the interval division center line, the installation surface of a fixed size divided into a multi-row crossbar or a multi-row column is uniform. Sized interior boards can be easily and aligned and adhesively installed.

As with the above technique, masking tape can be used for interior purposes, but when the general public, especially infants and children, for art education such as painting oil paintings or watercolors, they do not have the power of their hands yet or have not been able to exert precise hand movements. If it is not possible to draw a picture such as, it is necessary to provide an environment in which a picture with a feeling like watercolor or oil painting can be expressed using a specially made masking tape.

However, the above-described prior art is limited in use for the purpose of such art education, so there is a need to develop a novel and advanced masking tape that has been improved so that children and toddlers can express various pictures in a simpler and more convenient way. It is the actual situation.

The present invention has been conceived to overcome the problems of the above technology, and its main object is to provide a masking tape capable of expressing various pictures by attaching it to an original plate such as drawing paper by easily tearing it open in a mosaic method.

Another object of the present invention is to be able to easily implement a picture or image to be expressed through various painting materials such as crayons as well as various painting areas such as oil painting and watercolor beyond applying the mosaic method.

Another object of the present invention is to allow a picture with a three-dimensional effect such as a hologram to be expressed.

A further object of the present invention is to improve adhesion as well as spreadability by further including an adhesion aid having improved adhesion.

In order to achieve the above object, the masking tape for art play of a mosaic method according to the present invention is made of a material that is torn in a state of a strip shape, and includes a front portion in which a color layer having a specific color is stacked, and the front portion A tape body consisting of a rear portion on which an adhesive layer is formed as an opposite surface; It characterized in that it comprises a; a roll (roll) of the tape body rolled.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale, and the same reference numerals in each drawing refer to the same elements.

1 is a perspective view showing a basic embodiment of the masking tape of the present invention.

As can be seen from FIG. 1, the masking tape of the present invention is based on a structure in which the tape body 100 having a strip shape is rolled on a roll 200, which can be said to be the same as a known tape.

In particular, the masking tape of the present invention is characterized in that it can be used to complete a picture or image in a manner and format such as a mosaic by a user tearing a part of the tape body 100.

Mosaic has a dictionary meaning that a material such as mortar, lime, cement, etc. is bonded to an original plate to express a pattern or picture. In the present invention, this mosaic method is applied to the tape body 100 After forming the color layer 111 having a color, the tape body 100 is easily ripped to the size desired by the user and pasted on a disc such as paper, drawing paper, A4 paper, or sketchbook to express the finished picture, image, and pattern. will be.

That is, as can be seen from FIG. 1, repeating the operation of tearing a part of the tape body 100 of the present invention and then attaching it to the original plate can give a feeling as if a mosaic-type picture is completed, and in this process, the user can perform it alone. Or, when the user is an infant/child, they can complete the picture with a leader or parent, providing a unique advantage to educate users of beneficial art play from a leader or parent perspective.

.

Hereinafter, a specific configuration and operation of the tape of the present invention will be described.

The tape body 100 refers to a strip-shaped structure that exhibits a specific color while having adhesive properties, and is defined as consisting of a large front part 110 and a rear part while ignoring the side surface because it is made of a thin film. can do.

The tape body 100 is made of a material that can be torn. Among these materials, the most common material may be called paper, and various materials used in a known masking tape having a property capable of tearing may be applied.

The front part 110 refers to a portion of the tape body 100 that is exposed to the naked eye of a user, and a color layer 111 having a specific color is stacked thereon.

The color layer 111, which will be described later, refers to a layer to which at least one color is added through various expression techniques, and the color layer 111 is the front part 110 of the tape body 100 through a known printing method. Alternatively, it is possible to perform lamination treatment on the front part 110 by adding a color to the front part 110 during the manufacturing process of the tape body 100 or adding a color to the tape body 100.

That is, since the method of laminating the color layer 111 on the front part 110 follows various known color formation methods, a detailed description will be omitted.

As can be seen from FIG. 1, the color layer 111 may be formed in a state including one unique color for each tape of the present invention, such as red, yellow, and blue.

In addition to this, the color layer 111 can of course be formed by mixing white with a unique color, and furthermore, even when red is a unique color, for example, even when red is a unique color, the saturation and brightness of red are differentially processed according to the detailed area to provide various colors. Can provide. In addition, it is also possible to express a specific pattern, image, and figure by combining multiple colors beyond just having a color without a specific pattern.

Furthermore, it is possible to form a UV coating layer on the surface of the color layer 111 on the front surface 110 on which the color layer 111 is stacked.

The UV coating layer blocks ultraviolet rays irradiated to the front part 110 as well as prevents discoloration/discoloration of the color layer 111 while ensuring durability to prevent scratches from easily occurring on the tape body 100, When rolling the tape body 100 on the roll 200, which will be described later, the adhesive layer formed on the rear portion of the tape body 100 adjacent to the front portion 110 is pressed to prevent the problem of being easily removed from the roll 200 and not being used. It provides a surface treatment function.

Such a UV coating layer may be formed on the surface of the color layer 111 by coating a known UV blocking agent, and it is also possible to apply a known UV coating treatment method and a UV blocking agent.

Although not shown in the drawing, the rear portion is formed with an adhesive layer as the opposite surface of the front portion (110).

The adhesive layer is formed by including either an adhesive or an adhesive, and can be understood as a concept including both an adhesive layer and an adhesive layer in a narrow sense.

As an example of an adhesive layer having narrow adhesive properties, it is possible to include a glue, as well as an acrylic adhesive with enhanced physical contact stability.

In addition, examples of the adhesive layer having a narrow adhesive property may include thermoplastic resin-based adhesives such as epoxy-based and polyester-based as well as hot-melt adhesives.

In particular, in the present invention, since the tape body 100 is made of a material that is torn, the adhesive layer has too strong adhesive properties or too weak adhesive properties. It is preferable to include a material having an adhesive property, for example, a hot melt adhesive (HMA), which cannot be removed or is attached to the original plate too easily, and this will be described in more detail below.

The roll 200 (shown in Fig. 5) has a ring shape having a hollow in the center portion, and thus a structure that provides a basis for rolling the tape body 100 by a predetermined length. As, this roll 200 also takes the same structure as a known tape, as well as a method of rolling the tape body 100 on the roll 200 can be implemented through a known rolling process, so a detailed description will be omitted. .

In summary, according to the masking tape of the present invention, by adding various colors based on a material that can be easily torn by the user's manipulation, such as paper, it is fun and easy to complete a picture that can give a mosaic-like feel. , In addition to ensuring the user's fun, from the perspective of a leader or parent, it provides a characteristic capable of performing beneficial art play for users such as children.

2 is a conceptual diagram illustrating a state in which the front portion of the tape body exhibits a watercolor texture, FIG. 3 is a conceptual diagram illustrating a state in which the front portion of the tape body exhibits an oil texture, and FIG. 4 is a front portion of the tape body showing a crayon texture. It is a conceptual diagram illustrating the state.

First, referring to FIG. 2, the front portion of the tape body may have various colors, respectively, and it can be seen that the color layer exhibits a texture similar to that of watercolor.

Here, the texture like or similar to watercolor refers to a state in which a specific color is expressed in a low density (like a pastel tone) as if it was released or released in water, and when red is illustratively described in FIG. 2, a single dark brightness/ It means expressing the same texture as having a relatively thin and blurry brightness and saturation, as well as having a smooth and smooth surface state in a state including medium white, not saturated red.

The color layer 111 having a watercolor texture may be implemented by attaching or printing a color film layer previously expressed as a watercolor texture in the printing step of the color layer 111.

In addition, as can be seen from FIG. 3, the color layer 111 may be expressed in a texture such as oil painting.

Oil painting is a painting area that emphasizes three-dimensional effect and texture. In other words, the oil painting texture-based color layer 111 is expressed so that the feeling of oil painting can be obtained by adding the same color or different colors to the same location several times. Means that it has become.

In this case, it is possible to actually form the surface of the color layer 111 by applying a specific color several times, or to fabricate it by grafting a printing process based on a master film expressed so as to feel a pre-made oil painting.

4 shows that the color layer 111 is expressed to have a crayon texture.

Crayon is a painting material obtained by dissolving paraffin or wax in a pigment to solidify it, and the color layer 111 according to FIG. 4 can be said to have a texture made of coarse particles like this crayon.

Again, it is possible to form the color layer 111 by printing on the front surface of the master film expressed to have a crayon texture.

In summary, according to the color layer 111 according to FIGS. 2 to 4, not only expressing a painting technique such as an actual oil painting or watercolor, but also giving a sense of reality such as using a painting material such as crayons, and a more diverse and colorful mosaic method. You can create a picture or image or provide a characteristic that can be expressed.

5 is a conceptual diagram illustrating a state in which the front portion of the tape body exhibits a holographic feel, and FIG. 6 is a conceptual diagram illustrating a state in which a perforation line is formed in the tape body.

A hologram is a three-dimensional photograph made of a three-dimensional image, which is made using the principle of holography. In more detail, the hologram can be said to be a medium in which interference fringes reproducing a three-dimensional image are recorded, and the color layer 111 according to FIG. 5 can be said to be produced by printing the color expressed by the hologram described above.

Referring to FIG. 5, it can be seen that the tape body 100 having the color layer 111 expressed as a hologram is ripped and pasted in a mosaic method to express a'horse' image. You can express a sense of life like playing.

In addition, referring to FIG. 6, it can be seen that the tape main body 100 is not formed as a single unit but can be separated into fine pieces.

That is, as shown in FIG. 6, a grid-like arrangement or a perforation line 130 having a straight array in the length direction at a predetermined interval is formed so that each piece can be opened and used based on the perforated line 130.

According to the tape body 100 according to FIG. 6, since each piece has a neat and formal shape without being ripped randomly, it can be appropriately used when producing a picture or image to be completed based on a specific format rather than a random state. have.

In conclusion, according to the embodiment according to FIGS. 5 and 6, rather than forming various three-dimensional effects or emphasizing a mosaic feel, a feature that emphasizes expandability in use that can be used by further emphasizing a formal feeling is provided.

As mentioned briefly above, the adhesive layer of the present invention may include a hot melt adhesive so that it can be suitably used for a tape body having basic properties made of a material such as paper torn.

Hot Melt Adhesive (HMA) refers to an adhesive that is made into a solid without adhesive strength and then melted by applying heat when used.In the present invention, a solid having an adhesive property is melted and laminated on the surface of the rear part of the tape body. It can be said that it was one thing.

The hot melt adhesive may be made of a variety of materials. For example, a mixture of a base polymer, tackifying resins, and wax may be described.

The basic polymer provides the role of forming the basic framework by imparting rigidity to the adhesive, and since the adhesive resin has a low molecular weight, the basic polymer with a relatively high molecular weight plays a role in controlling the overall physical properties and viscosity of the hot melt adhesive. do. Wax provides a function that assists in exerting the optimum adhesion for each use condition by adjusting the physical properties of the adhesive resin.

In addition, hot melt adhesives can be classified according to their constituent components, and representative examples include ethylene-vinyl acetate-based, polyolefin-based, styrene block copolymer-based, polyamide-based, polyester-based, and urethane-based (reactive hot melt).

Among them, ethylene vinyl acetate (EVA: Ethylene Vinyl Acetate), a representative material of ethylene-vinyl acetate, not only has low crystallinity under low price conditions, but is colorless and transparent, and has a fine polarity conducive to adhesion. When mixed with a resin, it provides a role of preventing the problem of poor adhesion.

In addition, ethylene vinyl acetate is a material whose transparency and melting temperature can vary depending on the content of vinyl acetate (VA). It is a material with good processability, flexibility, electrical insulation, water resistance, moisture-proof and cold resistance, and has high surface friction. There is an advantage to have.

In particular, when such a hot melt adhesive includes EVA, it is more preferable that the adhesive layer further includes an adhesion aid including ethylene glycol.

In this way, when the adhesive layer includes an adhesive auxiliary, the adhesive layer may include 80 to 90 parts by weight of the hot melt adhesive and 10 to 20 parts by weight of the adhesive auxiliary. In other words, it means that the hot-melt adhesive can have a relatively high weight ratio while the hot-melt adhesive is set as the main adhesive, and an adhesion aid can be added as an auxiliary adhesive at a relatively low weight ratio.

Ethylene glycol (Ethylene glycol) further improves the strength of the adhesive strength of the included adhesive layer, and at the same time provides characteristics that complement flow and spreadability, and provides a water-dispersible resin having sticky properties in an adhesion aid including various components to be described later. It can play a role as a basic raw material for manufacturing.

Additionally, the above-described adhesion aid may be prepared through a first material manufacturing step (S100), a second material manufacturing step (S110), and an adhesion aid completion step (S120) in a state including various components, and a specific manufacturing method for this Is as follows.

Figure 7 is a flow chart showing the process of manufacturing the adhesion aid of the present invention.

First, the first material preparation step (S100) is toluene (Toluene) 10 to 20 parts by weight, acetone (Acetone) 15 to 30 parts by weight, methyl ethyl ketone (Methyl Ethyl Ketone) 20 to 40 parts by weight, ethyl acetate (Ethyl Acetate). ) As a process of preparing the first material by mixing 20 to 40 parts by weight, this process can be said to be a process of preparing a solvent required for the manufacture of an adhesion aid.

Here, toluene is a transparent, colorless liquid having a characteristic fragrant odor, and is used in the manufacture of aviation fuels, automobile fuels, solvents, and other chemical substances, and in the present invention, it is used as a solvent for manufacturing an adhesion aid.

Acetone is a highly volatile, flammable, transparent, colorless liquid that has an irritating and slightly sweet smell. Methylethylketone is an alcohol oxide and is used as a solvent in an industrial process or a material in the synthetic rubber industry.In the present invention, toluene and Likewise, it is used as a solvent in the process of completing the adhesion aid.

Ethyl acetate is a volatile and flammable, colorless liquid as an ester component of ethyl alcohol and acetic acid, which is also mixed with a second material to be described later to serve as a solvent for preparing an adhesion aid.

Next, the second material manufacturing step (S110) includes 20 to 35 parts by weight of NDI (1.5-Naphthalene diisocyanate), 20 to 35 parts by weight of blocked isocyante, 10 to 20 parts by weight of ethylene glycol, MPD ( 3-Methyl-1,5-Pentane diol) is a process of preparing a second material by mixing 10 to 20 parts by weight and 15 to 30 parts by weight of an aqueous dispersion resin, and the bonding aid completion step (S120) is the first material 50 to 70 This is a process of completing the adhesion aid including parts by weight, 20 to 45 parts by weight of the second material, and 0.5 to 5 parts by weight of di-n-butyl tin dilaurate (DBTDL).

Here, NDI and block isocyanate are one kind of isocyanate, and ethylene glycol, MPD, and water dispersion resin are one kind of polyol. In addition, as mentioned above, ethylene glycol is a material that simultaneously increases the strength of the adhesive strength of the hot melt adhesive.

When these isocyanates and polyols react, polyurethane having a viscosity of about 1,500 cps and tackiness based on 25°C is produced, and at this time, DBTDL plays a role as a reaction catalyst for the reaction between these isocyanates and polyols.

In addition, the water-dispersion resin is a material having a stickness property and provides a function that can be well attached to the object, and the blocked isocyante is mixed with the water-dispersion resin to proceed with the urea reaction. However, by crosslinking through such a reaction, it accelerates the speed of curing and plays a role as a curing agent that can improve mechanical strength during curing. At this time, a specific method of manufacturing the water dispersion resin will be described later.

The adhesive aid manufactured through this process not only improves the adhesive function of the adhesive layer, but also has a high viscosity, so it can help to improve the spreadability and flowability of the adhesive layer.Through this, the adhesive layer has an appropriate thickness on the back side of the tape body. It can be applied well.

Furthermore, the water-dispersion resin described above may be prepared through an intermediate material manufacturing step and a water-dispersion resin completion step.

First, the intermediate material preparation step is a process of preparing an intermediate solution by mixing 85 to 99 parts by weight of water and 1 to 15 parts by weight of an emulsifier and then stirring at a speed of 800 to 1200 rpm for 20 to 50 minutes. Here, it is preferable to use tertiary distilled water (water purified by passing through an ultra filter).

In addition, emulsifiers surround molecules in a solution to prevent coagulation by colliding between molecules and impart stability.For example, PEG-PPG-PEG (Poly(ethylene glycol)- block-poly(propyleneglycol)-block-poly(ethylene glycol)) can be used.

Next, the water-dispersion resin completion step is a process of mixing 45 to 60 parts by weight of an intermediate solution and 40 to 55 parts by weight of a polyaspartic resin, followed by stirring at a speed of 1800 to 2200 rpm for 2 to 5 hours to complete the water dispersion resin.

Here, the polyaspartic resin is a material that is commercially available as a coating agent, has excellent resistance to ultraviolet rays and durability, and is a coating material capable of quick drying.

The water-dispersible resin thus prepared can improve the overall durability of the adhesive layer and provides an advantage of shortening the drying speed when the adhesive layer is applied to the rear surface of the tape body 100 and then dried.

As described so far, the configuration and operation of the masking tape for the mosaic-type art play according to the present invention are expressed in the above description and drawings, but these are only examples and the idea of the present invention is limited to the above description and drawings. Of course, various changes and changes are possible without departing from the technical spirit of the present invention.
