Description

Image transfer coating method of plate material

The present invention relates to an image transfer coating method of a plate such as plywood, and more particularly, a high resolution transfer for forming a predetermined pattern or image on the surface of the plate material can be carried out continuously without smearing or bleeding of ink, The present invention relates to an image transfer coating method of a plate material that enables mass production as well as multi-product production.

In general, the plate material refers to a plate-like raw subsidiary material having a property of a material that cannot be produced in a roll form. There are various kinds of raw subsidiary materials, such as wood plywood, gypsum panel, cement block, and plate. Examples include marble, acrylic plates and floor deco panels.

Among them, the wood plywood cuts out the wood thinly and superimposes them so that the fiber directions are perpendicular to each other. The overlap is 3, 5, or 7 sheets of thin plates, and the odd number is used so that the top plate and the back plate have the same fiber direction. A sheet of thin sheet is called veneer, and plywood is a collection of veneers.

There are general plywood, core plywood, untransmitted plywood, waterproof plywood, and TEGO plywood depending on the manufacturing method and usage. In addition, MDF, PB, gypsum board, lumber / plate, synthetic wood, natural deck material, laminated wood / stair material, There are various types such as special wood, flooring (flooring / flooring), doors / door frames and moldings. These plywoods are widely used as interior and exterior materials for architecture and interior, and are the most common architectural interior materials.

Due to the nature of plywood, it is made of wood with overlapping veneers or pressed sawdust, so the surface layer is either in the form of wood, pressed form, or in the form of a wooden pattern on the surface, or using a separate adhesive film on the surface. Butch products have been proposed.

In construction and interior, plywood is used more than any other materials, and after installation, the surface of the paint is used as a waterproof paint or wallpaper. Surface paints include varnish, which protects the plywood's own pattern, and paint, which paints a separate color. Although it has mass production form due to the characteristics of plywood, it does not escape the solid wood pattern of the plywood itself. Image representation is impossible.

Although gypsum panels are not common, they are dried and processed by diluting and mixing powdered gypsum powder with water or a mixture. It is used as part of architectural finishes and is now used for the direct application of diluted gypsum mixture to the finish. Gypsum panel-type construction and finishing construction is to give a pattern or a separate attachment to the finishing material or white surface used for interior.

Cement blocks are used for building finishing materials and interiors with marble as the construction finishing technology is widely used in the exposed cement process. Cement block is constructed after the process of fixing cement in the mold due to its characteristics, and is used by applying waterproof paint or coloring paint on it.

Marble plate is a building material that can process raw stones in various forms, or because of the limited resources and characteristics of stone, it is a building material that has a lot of difference in price even if it is manufactured as a building plate. There is a limit that cannot be expressed other than the characteristics of the stone itself.

Acrylic panel is a product that mixes the solvent-based acrylic raw material with pigment or pours a transparent solvent into a mold and compresses it with a press. Currently produced products give a pattern or color during press work and silk screen after production. It is used in various materials through printing, film adhesion, and direct printing machines, and is a preferred material for interior cleaning. Such acrylic panels have been widely used due to the processability of acrylic cleaners, but have limitations in the color representation of silk screens and expensive manufacturing processes of some direct prints.

There are two types of floor deco presses that produce a mixture of PVC series, and during the production, the film-type design is bonded with a heat press to produce a press or a square or rectangular form. At this time, the design of the surface used in the form of a film is mainly attached to the surface printed on the film through the gravure printing through the heat, there is a problem that it is very difficult to process a high-resolution design print in the production process. In addition, after a mixture of wood sawdust or PVC-based mixture into a certain frame and then the production process of dipping with heat and pressure, the surface design used in this case is mainly the color of the wood surface pattern.

Modern society needs various types of building materials and interior materials, but most of the plate materials used are used in post-processing forms such as painting or film bonding. This is because it is very difficult to express and process various designs and colors at the production stage.

As such, in order to express an image on the surface of a plate, an image or color is expressed through painting, paper or film adhesion, or silk printing on the surface of the plate. Silk or digital printing technology is used to express an image or color on the product itself. Silk printing has limitations in workability, color representation, and continuity due to color representation and sheet size, and digital printing is too expensive to predict demand. As such, the method of directly printing or transferring an image on a plate has a very difficult problem.

Therefore, the present invention has been proposed to solve the above-mentioned conventional problems, and the present invention can continuously execute a high resolution transfer for forming a predetermined pattern or image on the surface of the plate-like material without smearing or bleeding of ink, An object of the present invention is to provide an image transfer coating method of a plate material that enables mass production as well as small quantity multi-product production.

In addition, the present invention can easily implement a high-quality printed material by transferring a variety of high-quality printing to the surface of the plate with mass production, for example, in the case of wood plywood can express a product containing a variety of designs on the surface of the plywood in a variety of high definition In the case of cement blocks, the cement block surface can be transferred to marble pattern to create high added value.In the case of gypsum panel, it can be processed into interior and installation as a mural through the transfer process, and high color resolution on various plates.

Provision step (S100); Providing an image print having a transfer image including an image to be transferred to the transfer target plate material, wherein the image print is a transfer image print preparing step of preparing a printed image or printed image print on a printing paper coated with a predetermined coating on a sheet of paper; (S200); Providing an ink movement solvent for moving the transfer image of the printed matter on the plate-shaped material (S300); An ink transfer solvent coating step of applying an ink transfer solvent on the plate-shaped material (S400); An image transfer step (S500) to the plate-like material which transfers the print-out of the transfer image to the plate-like material through the ink transfer solvent while moving the plate-like material and the transfer image printout; And a transfer completed plate material post-treatment step (S600) of recovering the base paper of the printed matter on which the transfer image is transferred to the plate material, and post-processing the plate material on which the transfer image is transferred.

Each step of the image transfer coating method of the plate material will be described in detail with reference to FIGS. 2 to 7. Figure 2 is a process diagram schematically showing the overall process flow of the image transfer coating method of the plate material according to the present invention, Figure 3 is a process of coating the surface of the plate material and the composition of the plate material prepared through the transfer material plate material preparing step Figure 4 is a cross-sectional view, Figure 4 is a process chart for applying the ink transfer solvent on the coating surface on the plate, Figure 5 is a view showing a cross-sectional view with the printing layer is printed ink is printed on the image printing dedicated paper and Figure 6 is a transfer image It is sectional drawing which shows the process of crimping | printing a printed matter with the ink movement solvent on the surface of the coating layer of a board | plate material. FIG. 7 is a process diagram schematically illustrating a process of separating an image of an ink transfer solvent integrated on a transfer material and a print coating layer on a transfer paper from a sheet of paper by pressing and fusion from a plate material.

First, the transfer target plate material preparing step (S100) is a step (S110) of cleaning (washing) the surface of the various plate-like materials produced first, and plate coating material 120 that can receive the color of the printing surface (transfer surface) ) The coating step (S120) for coating the original plate-like material 110, the drying / curing step (S130) for drying and curing the surface of the plate material in order to increase the processing efficiency after the coating step, and the surface of the plate material And smoothing the surface planarizing operation step (S140), and removing the foreign matter present on the surface of the plate-like material (S150).

In addition, due to the characteristics of the plate material, since the plate material, which is a raw material, has a high possibility of containing foreign matter on the surface during the manufacturing process, the pre-treatment foreign material removing step (S101) may be performed to perform a smooth and stable coating operation in the post-processing coating step. It is preferable to include.

The coating step (S120) is preferably coated with a transparent or white that can easily accept the color of the printing surface, it is preferable to vary the degree of coating according to the type of the product to be applied to the plate material.

The coating step (S120) may be made in a roller manner as shown in Figure 2, it may be made of a screen coating method or the like. Here, the plate coating material 120 to be coated in the coating step (S210) is provided with a coating material of the same series of components and the ink moving solvent to be described later in contact with the coating layer and the ink moving solvent of the plate-like material coated with the coating material in a later process This allows for smooth fusion with each other.

The foreign material removal step (S101, S150) is made of a cleaning method using a cleaning liquid or a blower method through compressed air injection.

Such a plate-like material is prepared and provided in a stacked form, for example, as shown in FIG.

Next, the transfer image printout preparing step (S200) will be described with reference to FIG.

Transfer image print preparation step (S200) is a process of preparing a print on which a predetermined image required for transfer is printed for the first time, at this time, the printed material is basically determined through various printing methods on the surface of the original paper 210 on which the transfer image is printed. It is made of a structure in which the image is printed, and includes a printing / printing step and the drying and removing the foreign matter (S210, S220).

Specifically, the printed matter includes a base paper 210 on which the transfer image is printed, and a transfer image printing layer 220 printed on the base paper 210 as shown in FIG. 5.

The base 210 is a material capable of printing and other coating process on the surface, such as a film of paper or other synthetic resin material.

The print layer 220 contains the ink 250 of the transfer image to be printed on the paper, and at the same time reacts with the ink transfer solvent 300 described later in the process of transferring to the surface of the plate-like material to be transferred. It serves to move the, the ink containing component 221 and the adhesive component 222, the coating component 223 and the peeling component 224 is made of a mixed structure.

At this time, the ink receiving component 221 used serves to hold the printed image ink 250, and a mixture of silica, clay, talc, calcium carbonate, and the like is mixed. Or optionally applied.

The ink receiving component 221 is applied in the form of particles (micro units, for example, 2 μm to 10 μm) so that the voids are formed between the particles so that the ink 250 is positioned in each gap.

In addition, the ink-receiving component 221 is mixed with a water-resistant solvent so that the ink 250 is easily fixed in each pore and has water resistance, thereby preventing bleeding of the ink.

The adhesive component 222 serves to maintain the printed image (image to be transferred) stably by maintaining the ink receiving component 221 attached to the surface of the base paper 210, carboxymethylcellulose, Components such as polyvinyl alcohol, latex and acryl are used.

In addition, the coating component 223 serves to prevent bleeding of the ink and to protect the base paper 210 from moisture, and a material of the same series as the ink moving solvent is used.

In addition, the peeling component 224 allows the print layer 220 to be separated from the base paper 210 smoothly during the transfer process in a later process. Wax, fluorine, or other silicon-based components are used. The print layer 220 is coated on the surface of the base paper 210 through a coating method such as air-knife or gravure, which is generally used.

Here, the print layer 220 is formed as a micro-pore as a whole as the ink receiving component 221 mentioned above to allow the ink movement solvent 300 to be described later penetrates into the print layer 220 through the void.

When the image is printed on the substrate by such a structure, the ink 250 of the image is not directly printed on the surface of the paper 210, but is printed while the ink is absorbed by the printing layer 220, and thus on the surface of the paper 210. Will be exposed to.

For reference, the image printing of the printed matter can be selected and applied from various methods such as a printing method capable of mass production, that is, rotation printing, gravure printing, and digital printing.

As described above, the prepared printed matter is wound in a roll form on the printed matter unwinding roller as illustrated in FIG. 2, and may have a structure in which one end portion may be released while moving along a predetermined path, or may be formed in a stacked state.

Next, the ink transfer solvent preparing step (S300) is to prepare a solvent that serves to move the ink 250 in the ink receiving component 221 to the surface of the plate-like material in the transfer process image.

The ink movement solvent 300 is largely made by mixing the main solvent 311, the diluent 312 and the viscous agent 313 (see FIG. 6).

The main solvent 311 of the ink-using solvent 300 serves to substantially move the printing layer 220 and the ink of the printed matter 200 to the surface of the plate-like material during the transfer process, the coating layer 120 of the plate-like material And the same material as the coating component 223 in the printed layer of the printed matter.

In other words, when the material of the coating layer 120 is polyvinyl chloride (PVC), the main solvent 311 and the coating component 223 are also made of polyvinyl chloride.

In addition, when the coating layer 120 of the plate-like material is polyurethane (POLYURETHANE), the main solvent is also polyurethane.

The reason for forming the material of the coating layer 120, the main solvent 311, and the coating component 223 in the same manner is that the materials of the same component have high compatibility and adhesion to each other. The print layer 220 of the printed matter is easily fused and adhered to the coating layer 120 of the plate material through the moving solvent 300, resulting in the print layer being moved to the plate material. This will be described in detail in the following description of the transfer process.

Subsequently, the diluent 312, which is another element constituting the ink transfer solvent 300 together with the main solvent 311, induces dilution of the main solvent 311 to form a main material 311 and a plate-like material which is a transfer object. It serves to help the fusion between the coating layer 120 and the coating component 223 of the printed matter. As the diluent, ethylbenzene, methyl ethyl ketone (MEK), eco solvent, etc. are used, and in order to increase the dissolution efficiency between the diluent and the main solvent, a solvent such as formamide, tetrahydrofuran (THF) and ethyl acetate (EA) is added. Can be used as

Viscosity agent 313, which is another element constituting the ink transfer solvent 300, imparts proper viscosity of each component constituting the ink transfer solvent to allow the ink transfer solvent to be used in a liquid state and at the same time. It serves to ensure proper adhesion between the solvent and the coating layer 120 and the print layer 220. Bisphthalide, ethyl cellulose, etc. are used as a viscous agent.

For reference, the diluent (or dissolving agent) 312 and the viscous agent 313 except for the main solvent 311 is not limited to the above-mentioned components can be selected and applied among other components having the same function, and to the environment or human body It is used to the extent that it does not adversely affect it.

Next, the image transfer step to the plate-like material (S400) is a process in which the substantial transfer is performed, the ink transfer solvent 300 is applied to the plate-like material or the printed matter (see Fig. 4), the applied ink transfer solvent is printed layer (Or the coating layer) is primarily fused, and the fused ink transfer solvent is tightly bonded to the printing layer (or coating layer), and the coating layer of the plate-like material and the coating component of the printed material are mutually fused together through the ink transfer solvent 300. Secondary fusion, then the image of the print is completely transferred to the plate material (see FIGS. 6 and 7).

Specifically, the application of the ink transfer solvent 300 to the plate-like material or printed matter is to apply the ink transfer solvent 300 on the surface of the print, that is, the print layer 220 so that the ink transfer solvent 300 is the printed layer of the print Or to be applied directly to the surface of the plate-like material, ie, the coating layer 120.

For example, as illustrated in FIG. 2, the ink moving solvent 300 is applied to the interval printing layer 220 during the movement of the printed matter wound in a roll form by using an application roller (first roller). It may proceed in a manner to apply on the printing layer, or in a manner of applying to the coating layer 110 of the plate-like material at the same time as the unwinding of the plate-coupling roller in the section during the movement that the plate-like material is unwinded by the plate unwinding roller. .

Here, the coating method of the ink movement solvent 300 may use a roller method, a blade method or an air knife method or a curtain method in addition to the injection method as shown in FIG.

The ink movement solvent 300 applied as described above is the same material as the coating component 223 of the printing layer 220 and the coating layer 120 of the plate-like material, and thus the printing layer 220 or the coating layer 120 at the same time of application. Penetrating into the coating component 223 or the coating layer 120 is fused with the first fusion process is made.

Then, the close bonding process is a process of laminating and pressurizing the printed matter and the plate material, and as shown in FIG. 2, the printed material and the surface-treated (coated) plate material which have undergone the primary fusion process along a predetermined path. It moves and progresses in such a way as to pass between a pair of rollers (second and third rollers). In this case, as described above, at least one of the printed matter or the plate-like material is in a state in which an ink transfer solvent is fused through a first fusion process.

In this process, the plate-like material and the printed matter laminated are pressed by a pair of rollers (second and third rollers), and at this time, the ink-moving solvent is applied to the printed layer 220 and the coating layer 120 of the plate material. The secondary fusion (120 + 300, 220 + 300) is made of the mutual fusion 300 is in contact with each other is made. As described above, since the components of the coating layer 110 and the ink migration solvent 300 of the plate material are in the same series, mutual compatibility is possible.

Therefore, the ink transfer solvent 300 is in the state of primary fusion with the print layer 220 of the printed matter, and also penetrates into the coating layer 120 of the plate-like material in the close bonding process of the printed matter and the plate-like material, and is thus secondaryly fused. The printing layer 220 is in a state of being integrated with the coating layer 120 of the plate-like material through the ink moving solvent 300.

Then, in the state of undergoing the secondary fusion process, the printed matter and the plate-like material pass through a pair of rollers (fourth and fifth rollers) as shown in FIGS. 2 and 7, and the printed matter is the sixth roller (the winding roller). The printing paper 210 is wound up by) so that the plate material and the printed matter are separated from each other.

At this time, the print layer 220 of the printed matter is peeled off from the base paper 210 by the fusion force with the solvent for moving ink 300 is moved onto the coating layer 120 of the plate-like material, wherein the print layer 220 is an image ink ( Since 250 is contained, the print layer 220 eventually moves to the surface of the plate material (coating layer 120), so that the image of the printed matter is also moved to the coating layer of the plate material. In this case, the transfer image ink 250 may be inverted and printed on the transfer paper surface 220 so as to display a normal image on the surface of the plate material after the transfer is completed.

The printed matter separated from the plate-like material remains only the base paper 210 and the image (image ink) printed on the base paper 210 is transferred to the coating layer surface of the plate-like material.

Next, the transfer-completed plate material post-processing step (S500), as described above, the plate-like material (image transfer-completed plate-like material) separated as the original print image is separated, but the remaining print is wound by a sixth roller (winding roller) ) Is finally completed through a coating step of coating with a predetermined coating material (eg, UV coating or UV coating film) to protect the transferred image and a drying step of drying the coating material.

As described above, the image transfer coating method of the plate-like material according to the present invention is performed after the bonding between the printed material and the plate-like material is made through the ink transfer solvent (that is, in the intervening state), and then the ink transfer solvent separates the printed layer on the print. It is a concept of separating from printed matter and moving to the surface of the plate material.

According to the image transfer coating method of the plate-like material of the present invention described above, the transfer process is carried out as compared to other methods by transferring the ink of the substrate to the plate surface by simply bonding the plate and the printed material through the ink transfer solvent. There is an advantage that can be made quickly.

In addition, since the present invention is a form in which the ink transfer solvent is fused to the print layer of the printed matter, the print layer is removed from the printed material and taken to the surface of the plate workpiece, so that the ink contained in the print layer moves together with the print layer without loss. Compared with other printing methods, there is an advantage of obtaining a high resolution.

In addition, the present invention can simplify the equipment required for the transfer process, diversify various color expressions and image expressions to facilitate the diversification of the final product, and convert the production of plate materials in the state of image transfer completed into mass production as well as small quantity production of many kinds. There is an advantage to this.
