Description

{Apparatus and method for realizing patterns with improved productivity}

The present invention relates to a device and method for implementing a pattern on a substrate, and more particularly, to an ink composition using a UV-curable paint, and in the second step, a magnetic plate of the plate type is used as the magnetic body, and the ink composition is cured by a UV lamp, and a pattern is formed by the magnetic body, and then the pattern is immediately fixed to the substrate, thereby improving productivity.

In general, printing inks are in wide demand and come in a variety of types, making it difficult to categorize and name them in a single category. However, they can generally be categorized as follows based on the printing method:

Typical printing plate types include relief, flat, stencil, and intaglio printing. Accordingly, specific examples of printing inks include relief printing inks, newspaper inks, lithographic inks, flexographic inks, etc.; planar printing inks include single-sheet stencil inks, offset rotary inks, and stencil newspaper inks; intaglio printing inks include gravure inks and intaglio inks; stencil printing inks include screen inks and mimeograph inks; and other types of electronic printing inks or register inks used in printed wiring.

In the case of interior products to which such ink is applied, as the demand from consumers for forming sophisticated and aesthetic patterns is increasing, a method for implementing a pattern using a magnetic body has been proposed to meet this demand. This method for implementing a pattern includes a first step (S10) of applying an ink composition including a magnetically responsive material to a substrate (3), as illustrated in FIG. 1, and a second step (S20) of implementing a pattern using a magnetic body (230) on the substrate (3) to which the ink composition has been applied. Through the first step (S10) and the second step (S20), various patterns can be formed in a desired shape through the application of a magnetic field by containing a magnetically responsive material, and the printing process is simple, and printing and three-dimensional effects can be exhibited through a continuous process without being restricted by the substrate.

However, in the case of these prior technologies, although theoretical implementation methods were presented, there was a problem that they could not be actually commercialized. In other words, although a pattern was formed by the magnetic body, the pattern was immediately released, and there was a phenomenon in which the pattern was not fixed to the substrate, so there was a problem in that productivity was low for actual mass production.

Meanwhile, the above-described pattern formation method itself is widely known and is described in detail in the prior art literature below, so its description and illustration are omitted.

Korean Registered Patent No. 10-1342200 Korean Publication Patent No. 10-2008-0110584 Korean Publication Patent No. 10-2005-0021376

The present invention is to solve the above-described problems, and the ink composition uses a UV-curable paint, and in the second step, a magnetic body uses a plate-type magnetic plate, while curing the ink composition by a UV lamp, thereby forming a pattern by the magnetic body, and then allowing the pattern to be immediately fixed to a substrate, thereby providing a pattern implementation device and method with improved productivity.

However, the purpose of the present invention is not limited to the purpose mentioned above, and other purposes not mentioned will be clearly understood by those skilled in the art from the description below.

In order to achieve the above object, the present invention provides a method for implementing a pattern with improved productivity, including a first step (S100) of applying an ink composition containing a magneto-responsive material to a substrate (3), and a second step (S200) of implementing a pattern on the substrate (3) to which the ink composition has been applied using a magnetic body, wherein the ink composition uses a UV-curable paint, and in the second step (S200), a plate-type magnetic plate (1200) is used as the magnetic body, and the ink composition is cured by a UV lamp (1100) to form a specific pattern by the magnetic plate (1200) and the pattern is cured so that it does not come off by the UV lamp (1100).

In the above, the first step (S100) can be performed by micro gravure or comma coating.

In the above, the curing time by the UV lamp (1100) can be within 0.1 to 10 seconds, and the curing temperature can be within 210°C to 250°C.

In the above, the ink composition may additionally include one or more additives selected from the group consisting of inorganic pigments, organic solvents, plasticizers, stabilizers, dispersants, photoinitiators, and viscosity reducing agents.

In the above, the viscosity of the ink composition can be within 10 cP to 300 cP.

In addition, the present invention provides a pattern implementation device with improved productivity, which performs the pattern implementation method, wherein a substrate (3) to which an ink composition has been applied by the first step (S100) is moved in a vertical downward direction, and a UV lamp (1100) and a magnetic plate (1200) are respectively placed on both sides of the horizontal direction of the substrate (3), so as to form a specific pattern on the substrate (3) moving in the vertical downward direction by the UV lamp (1100) and the magnetic plate (1200), and the pattern is cured so as not to be loosened by the UV lamp (1100).

The features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings.

According to the present invention described above, there is an effect of improving productivity by forming a pattern using a magnetic body and then allowing the pattern to be immediately fixed to a substrate.

Hereinafter, preferred embodiments of the present invention will be described with reference to the attached drawings. In this process, the thickness of lines and the sizes of components depicted in the drawings may be exaggerated for the sake of clarity and convenience of explanation.

In addition, the terms described below are terms defined in consideration of their functions in the present invention, and may vary depending on the intention or custom of the user or operator. Therefore, the definitions of these terms should be made based on the contents throughout this specification.

In addition, the examples below do not limit the scope of the present invention, but are merely exemplary of the components presented in the claims of the present invention. Examples that include components that are included in the technical idea throughout the specification of the present invention and can be substituted as equivalents in the components of the claims may be included in the scope of the present invention.

A pattern implementation method with improved productivity according to one embodiment of the present invention includes a first step (S100) of applying an ink composition including a magneto-responsive material to a substrate (3), as illustrated in FIGS. 2 and 3, and a second step (S200) of implementing a pattern on the substrate (3) to which the ink composition has been applied using a magnetic body. At this time, the ink composition may use a UV-curable paint. The first step (S100) may be performed by a pressure roll (210) and a printing roll (220). Since the first step may use the conventional technology described above, redundant description and illustration thereof will be omitted. However, unlike the conventional technology, the present invention uses a UV-curable paint. The UV-curable paint can be divided into a radical polymerization system and a cationic polymerization system. Radical polymerization systems include acrylic types such as polyester acrylic, urethane acrylic, epoxy acrylic, and polyether acrylic, and thiol types such as polythiol acrylic derivatives and polythiol spiro acetal systems. In addition, the UV-curable paint includes an epoxy type such as an epoxy resin. The UV-curable paints described above have different characteristics such as curing speed, and an appropriate one is selected and used.

The present invention uses such a UV-curable paint, so that it is quickly cured by the UV lamp described above to form a pattern on the substrate (3), and then the pattern is immediately fixed on the substrate (3), thereby improving productivity.

In the case of conventional technology, although a pattern was formed by a magnetic body, the pattern was immediately released, so there was a problem that the pattern was not fixed to the substrate, and thus productivity was low for actual mass production. The present invention solves this problem, and as described above, the pattern is immediately fixed to the substrate by a UV lamp, thereby improving productivity.

Meanwhile, in the second step (S200), the magnetic body may use a plate-type magnetic plate (1200). Conventionally, a roller-type magnetic body was used, but in the case of the present invention, a plate type is used. According to the present invention, the magnetic force is applied more uniformly to the substrate, so that the pattern can be formed more uniformly on the substrate. After the pattern is formed on the substrate, the ink composition is cured by the UV lamp (1100) described above, so that the pattern is immediately fixed to the substrate. In other words, a specific pattern is formed by the magnetic plate (1200) and cured by the UV lamp (1100) so that the pattern does not come off.

By the above first step (S100), an ink composition including a magneto-responsive material is applied to a substrate (3), and this first step (S100) can be performed by micro gravure or gravure, or comma coating. The micro gravure refers to a precision coating method in which a radius of a coating roll is made small in order to minimize the contact angle between a film and a coating roll, thereby minimizing the contact range between the roll surface and the film, thereby uniformly applying a thin film of paint. The comma coating is a coating method in which a coating liquid is applied using a comma-shaped bar, and is used when the viscosity of the coating liquid is high or the coating thickness is increased. The ink composition can be applied to a substrate more uniformly and precisely by the micro gravure or gravure, or comma coating.

After performing the above first step (S100), curing is performed using the UV lamp (1100). More preferably, in order to improve drying efficiency, prevent cracking, and prevent deterioration of adhesion, the curing time is set to 1 to 60 seconds, and the curing temperature is set to 210 to 250 degrees Celsius.

The above ink composition may further comprise one or more additives selected from the group consisting of inorganic pigments, organic solvents, plasticizers, stabilizers, dispersants, photoinitiators and viscosity reducing agents, as described above for fixing onto a substrate.

At this time, it is also possible to improve workability by setting the viscosity of the ink composition to within 10 cP to 300 cP.

Referring again to FIGS. 2 and 3 below, a device (1000) for performing the pattern implementation method of the present invention will be described.

First, the substrate (3) to which the ink composition is applied by the first step (S100) is moved in a vertical downward direction. At this time, a UV lamp (1100) and a magnetic plate (1200) are respectively placed on both sides of the horizontal direction of the substrate (3). A specific pattern is formed on the substrate (3) moving in the vertical downward direction by the UV lamp (1100) and the magnetic plate (1200), and the pattern is hardened so that it does not come off by the UV lamp (1100).

Compared to the conventional method of using a roller-type magnetic body, the present invention uses a plate-shaped magnetic plate (1200). By using the magnetic body of the present invention, more uniform magnetic lines can be obtained, and thus a more uniform pattern can be obtained.

This will be explained in more detail with reference to Figures 4 to 6 below.

As described above, the first step (S100) can utilize a process such as microgravure or comma coating. Of course, in addition, all printing methods commonly known in the art can be included, and, although not particularly limited, for example, screen printing, offset printing, gravure printing, or rotary screen printing methods can be included.

The method for printing the ink composition using the above-described gravure printing method is not particularly limited, and printing can be performed using a general method in this field. However, as a specific example, it can include (1) a step of printing the ink composition on transfer paper using the gravure printing method to produce a transfer paper having a printed layer formed thereon; and (2) a step of transferring the printed layer formed on the transfer paper to the surface of a substrate.

Of course, in the first step (S100), the ink composition can be printed using a rotary screen printing method. The method of printing the ink composition using the rotary screen printing method is not particularly limited, and printing can be performed using a general method in this field. However, as a specific example, the ink composition can be injected as a raw material into a cylindrical screen net, and the printing surface can be coated by centrifugal force due to rotation.

This type of rotary screen printing method is advantageous for thick film printing, and has the advantage of being suitable for forming thick protruding patterns when the screen mesh is manufactured with a thick thickness.

The method of applying a magnetic field in the second step (S200) may also utilize a magnetic plate (1200). This magnetic plate (1200) may include a non-magnetic magnetic plate (1210) and a plurality of magnets (1220) provided on the magnetic plate (1210). At this time, the magnets (1220) may be formed according to a predetermined pattern, and as described above, by positioning a substrate on which an ink composition is printed to form a printed layer on one side of the magnetic plate (1210) on which a predetermined magnet (1220) pattern is formed, a pattern exhibiting a three-dimensional effect may be formed according to the pattern formed on the magnetic plate (1210).

At this time, in the case of the magnetic plate (1210) formed according to a certain pattern as described above, one or two or more may be used, and although not particularly limited, 2 to 10 may be used to form various types of patterns.

Of course, various configurations can be used in addition to these configurations. For example, in the case of applying a magnetic field using a magnetic chuck, a substrate on which the ink composition is printed and a printed layer is formed is moved via a conveyor belt or the like, and a magnetic chuck provided on the conveyor belt applies a magnetic field while reciprocating left-right or forward-backward in a certain pattern on the printed layer, and accordingly, a magnetically reactive material reacts to form a pattern that exhibits a three-dimensional effect.

In addition, the strength of the magnetic field applied to the ink composition in the second step (S200) is not particularly limited, but may be, for example, 50 Gauss (G) to 2000 Gauss (G), and preferably 80 G to 1500 G.

If the strength of the above magnetic field is less than 50 G, it may be difficult to form various patterns as described above, and if it exceeds 2000 G, there is a risk that the strength of the magnetic field is too strong and shape deformation may occur.

Additionally, the second step may further include a step of drying the ink composition in which the pattern is formed.

That is, as described above, if the ink composition printed on the substrate forms a certain three-dimensional pattern due to the bias of the magnetic reactive material, an interior product such as an interior film having an attractive appearance can be manufactured by drying it.

Here, the temperature and time conditions during the drying (curing) are not particularly limited, and the drying temperature and time commonly used in this field can be applied, but preferably, drying can be performed at a temperature of 210 to 250°C in order to improve drying efficiency, prevent cracking, and prevent deterioration of adhesion, and it is preferable that the drying time is also performed within 0.1 to 10 seconds in consideration of productivity and efficiency, as already explained.

In addition, the ink composition including the magnetically responsive material used in the present invention includes a binder and a magnetically responsive material. The binder is not particularly limited and may include any conventional binder that can be used in an ink composition in the printing field, and it is preferable to use a material that has excellent affinity with the magnetically responsive material and can disperse the magnetically responsive material well.

Examples of binders that can be used include acrylic resins, polyvinyl chloride resins, silicone resins, cellulose resins, polyester resins, polyamide resins, polyether resins, vinyl-based resins, epoxy resins, and urethane resins, and preferably, acrylic resins or vinyl-based resins that are mainly used in gravure printing methods suitable for mass production among printing methods can be used, but are not limited thereto.

For a more specific example, the acrylic resin that can be used in the present invention may be an alkyl (meth)acrylate such as methyl (meth)acrylate, and the vinyl resin that can be used may be polyvinyl butyral, polyvinylacetate, and polyvinylpyrrolidone.

In addition, the binder may be included in the composition in various contents considering the viscosity of the ink composition, ink adhesion, surface tension, etc., and is not particularly limited.

Meanwhile, in the present invention, the term ‘magnetically responsive material’ refers to a material that can implement various patterns in response to an applied magnetic field.

That is, since the ink composition contains such a magnetically reactive material, when a magnetic field is applied to the ink composition, the magnetically reactive material contained in the ink composition can form a certain pattern by reacting to the applied magnetic field. Accordingly, when the ink composition as described above is applied to various interior products, a luxurious and sophisticated appearance that can express a three-dimensional effect can be realized.

Here, the magnetically responsive material may include, without limitation, any material that can implement various patterns in response to an applied magnetic field according to the purpose of the present invention, but for example, it may include one or more of the lanthanide elements such as iron (Fe), nickel (Ni), cobalt (Co), lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), promethium (Pm), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb), and lutetium (Lu), and an alloy including one or more of the above-mentioned materials or an oxide thereof may also be used.

In addition, iron oxide may preferably be used, and specific examples of the iron oxide include, but are not limited to, ferrous oxide, red iron trioxide, yellow iron trioxide, or iron tetraoxide.

Furthermore, the magnetically responsive material may have an average particle size of 2 ㎛ to 1 mm, preferably 2 ㎛ to 100 ㎛, more preferably 2 ㎛ to 50 ㎛, and most preferably 2 ㎛ to 35 ㎛.

If the particle size of the above magnetic reactive material is less than 2 ㎛, it may be difficult to implement a three-dimensional pattern, and if it exceeds 1 mm, there is a concern that the amount of ink transferred may be reduced.

In addition, the magnetically reactive material may be contained in various contents within the composition, but may be contained preferably in an amount of 1 to 70 parts by weight, and more preferably in an amount of 5 to 50 parts by weight, based on 100 parts by weight of the total composition.

Meanwhile, in the ink composition, the magnetic reactive material may be included in an amount of 1 to 100 parts by weight per 100 parts by weight of the binder.

If the above magnetic reactive material is contained in an amount of less than 1 part by weight, it may be difficult to form a pattern that implements a three-dimensional effect on the appearance of the ink composition, and if it is contained in an amount exceeding 100 parts by weight, it is not efficient in terms of cost, and there is a concern that it may become difficult to perform the printing process as the content of other components is relatively reduced and the viscosity of the ink composition increases.

The magnetically reactive material as described above can exhibit polarization in response to an applied magnetic field, and can be uniformly mixed and dispersed with other components, such as a binder, included in the ink composition.

Furthermore, the ink composition including the magnetically responsive material may additionally include a non-magnetic material. When such a non-magnetic material is additionally included, a luxurious and sophisticated appearance that can more effectively express a visual three-dimensional effect can be realized, and such pattern implementation will be described in detail with reference to FIGS. 4 and 5 described below.

Fig. 4 is a schematic diagram showing a printing material (10) printed with an ink composition including a magnetically responsive material and a non-magnetic material, and Fig. 5 (Figs. 5a to 5c) is a schematic diagram showing a method of implementing a pattern using a magnetic plate of a specific pattern on the printing material (10) of Fig. 4.

As shown in the above drawings 4 and 5, a vertical pattern (20-a) can be implemented by applying a magnetic force through a vertical magnetic body (20) having a vertical pattern formed on a printing substrate (10) on which an ink composition including a magnetically responsive material (1) and a non-magnetic material (2) is printed on a substrate (3). (Figure 5a)

In addition, a horizontal pattern (30-a) can be implemented by applying a magnetic force to the printing material (10) through a horizontal magnetic body (30) having a horizontal pattern formed thereon (Fig. 5b).

Furthermore, as shown in Fig. 5c, a diamond-shaped pattern (40-a) can be implemented on the substrate by applying a magnetic force to the printing material (10) through a square magnetic body (40) in which a vertical magnetic body (20) and a horizontal magnetic body (30) are laminated. (Fig. 5c)

This is because the magnetically reactive material contained in the ink composition exhibits bias in response to an applied magnetic field, and the non-magnetic material fills the empty space created through the bias, thereby forming a pattern of a certain pattern, thereby efficiently expressing a visual three-dimensional effect and implementing a luxurious and sophisticated appearance. Therefore, the pattern implementation of the present invention can form various patterns in a desired shape, and since only the magnetic plate (magnetic body) needs to be replaced or added to change the pattern without replacing the device (printer), it can exhibit an economical effect, and it can enable the formation of various patterns by using various types of magnetic plates (magnetic bodies).

Furthermore, Fig. 6 shows a cross-sectional view of Fig. 5a, and referring to Fig. 6, the magnetic reactant (1) contained in the ink composition forms a pattern in the form of magnetic force lines due to the application of magnetic force, thereby further adding visual three-dimensionality.

However, the above-described matters are merely examples, and the three-dimensional pattern forming method of the present invention is not limited to the above-described matters, so a desired pattern can be formed on a substrate by utilizing the bias of a magnetically responsive material with respect to a magnetic field according to various other methods.

The above non-magnetic material is not particularly limited, and any material that does not react to an applied magnetic field may be used without limitation. For example, one or more selected from the group consisting of zinc (Zn), copper (Cu), aluminum (Al), titanium (Ti), ruthenium (Ru), and tantalum (Ta) may be used.

The above non-magnetic material may have an average particle diameter of 2 ㎛ to 1 mm, preferably 2 ㎛ to 100 ㎛, more preferably 2 ㎛ to 50 ㎛, and most preferably 2 ㎛ to 35 ㎛.

If the particle size of the above non-magnetic material is less than 2 ㎛, it may be difficult to implement a three-dimensional pattern, and if it exceeds 1 mm, there is a concern that the amount of ink transferred may be reduced.

In addition, the viscosity of the ink composition used in the present invention can be freely adjusted by the user within the viscosity range of the ink composition typically used for pattern printing, and is not particularly limited, but for example, an ink composition having a viscosity of 10 cP to 300 cP can be used to facilitate work during printing.

Meanwhile, the ink composition may additionally include one or more additives selected from the group consisting of inorganic pigments, organic solvents, plasticizers, stabilizers, dispersants, photoinitiators, and viscosity reducing agents.

The above additives are substances that can be added to impart various functions to the ink composition, and each substance commonly used in this technical field can be included in the ink composition of the present invention through various combinations.

For example, the above-mentioned inorganic pigment is a pigment that has low solubility in solvents and is applied to the target object as a particle, and especially when applied to a substrate, it is desirable to use a substance that allows clear and diverse patterns to be transferred to the substrate without loss of pigment due to heat generated during a firing process, etc.

Specific examples of the above inorganic pigments include carbon black, lead chromate (PbCrO ₄ ), cadmium yellow (ex CdS, CdS+ZnS), titanium yellow (TiO ₂ ·NiO ·Sb ₂ O ₃ ), chrome orange (PbCrO ₄ ·PbO), molybdenum orange (PbCrO ₄ ·PbMoO ₄ ·PbSO ₄ ), luminous tan (Pb ₃ O ₄ ), cadmium red (CdS+CdSe), manganese violet (NH ₄ MnP ₂ O ₇ ), prussian blue (Fe[NH ₄ ]Fe[CN] ₆ ·xH ₂ O), ultramarine (Na _6~8 Al ₆ Si ₆ O ₂₄ S _2~4 ), cobalt blue (CoO · Al ₂ O ₃ ), and chrome green (PbCrO ₄ +Fe[NH ₄ ]Fe[CN] ₆ ·xH ₂ O), emerald green (Cu(CH ₃ CO ₂ ) ₂ ·3Cu(AsO ₂ ) ₂ ), metallic luster pigments (e.g., aluminum powder (silver powder), bronze powder), fluorescent pigments (e.g., zinc sulfide), pearlescent pigments (e.g., basic lead carbonate, bismuth oxychloride, titanium mica), antifouling pigments (e.g., zinc, cuprous oxide), anticorrosion pigments (e.g., zinc chromate), etc., are not limited thereto.

In addition, for the purpose of improving adhesion, sintering properties, gloss, etc., one or more selected from the group consisting of glass frit, silica, alumina, and limestone may be additionally included in the pigment component.

The above-mentioned inorganic pigment may be contained in various contents in the composition, and is not particularly limited, but may be contained in an amount of, for example, 0.1 to 15 parts by weight.

In addition, the organic solvent is a substance added to control the viscosity of the ink composition according to the present invention, and serves to lower the viscosity, which may increase by containing a magnetically reactive material or an inorganic pigment, to a viscosity suitable for application to a printing process.

The organic solvent mentioned above may include any substance capable of controlling viscosity in this manner without limitation, and specific examples thereof include alcohol, acetone, methyl isobutyl ketone, or methyl ethyl ketone, and the content thereof is not particularly limited, and may be contained in an amount of, for example, 0.1 to 30 parts by weight.

When the content of the organic solvent is close to 0.1 parts by weight, there is a concern that the ink composition may become difficult to apply to the printing process as the viscosity increases, and when it is 0.1, it becomes a solvent-free type composition, so the viscosity is lowered by using a reactive monomer, etc. as a diluent. When it exceeds 30 parts by weight, the drying property is significantly reduced, and it may cause a whitening phenomenon and surface roughness due to solvent volatilization, so the drying should be carried out slowly to volatilize the solvent, and then the hardening bone agent should be added. At this time, the drying process may take a lot of time, so there is a concern that the efficiency may be reduced.

In addition, examples of the plasticizer include at least one selected from the group consisting of phthalic acid ester, trimellitic acid ester, phosphoric acid ester, polyester, and chlorinated paraffin plasticizers.

Additionally, examples of the stabilizer include at least one selected from the group consisting of metal composite stabilizers (e.g. Ba-Cd, Ca-Zn or Ba-Zn), tin-based stabilizers, phosphorus-based stabilizers and epoxy-based stabilizers.

The additives as described above can be appropriately added in various ways commonly applied in this field, taking into consideration the printing method to which the ink composition of the present invention is applied, the intended use, other components, etc.

After forming a pattern on a substrate by the present invention as described above, the pattern can be immediately fixed to the substrate, and the actual pattern formed by the present invention is shown in FIGS. 7 and 8, and these FIGS. 7 and 8 are photographs of a pattern implemented by the present invention, and it can be confirmed that a pattern can be implemented more efficiently and accurately by the present invention.

Although the present invention has been described in detail through specific examples, this is intended to specifically explain the present invention, and the present invention is not limited thereto, and it is clear that modifications and improvements can be made by those skilled in the art within the technical spirit of the present invention.

All simple modifications or changes of the present invention fall within the scope of the present invention, and the specific protection scope of the present invention will be made clear by the appended claims.
