Description

  The present invention relates to a woodgrain makeup in which woodgrain patterns used as interior materials such as floor materials, staircase materials, wall materials, and ceiling materials in buildings such as houses, and door furniture materials are expressed by inkjet painting. The present invention relates to a material and a manufacturing method thereof.

Conventionally, wood-grained decorative materials with a woodgrain pattern have been widely used as interior materials or joinery materials as described above, and various techniques have been proposed to make the expression closer to real woody materials. Yes.
For example, in Patent Document 1 below, a process of applying current to the surface of the base material to impart electrical conductivity, an ultraviolet curable powder coating material is applied on the base material, and the powder coating material is heated and melted after coating. There is disclosed a design manufacturing method including a process of forming a coating film, a process of irradiating the coating film with ultraviolet rays and curing, and a process of printing a design on the cured coating film.
According to this, it is said that by applying a clear paint after the printing step, a product having excellent durability, gloss and depth can be obtained.
However, the real woody material is glossy when the light received on the surface of the bark is reflected or scattered inside the cells, but the one described in Patent Document 1 below cannot express such glossiness. Met. That is, since the clear coating is applied to the entire surface of the base material, the entire surface is glossy, so that the gloss and shine peculiar to the real wood grain cannot be fully expressed.

Further, in Patent Document 2 below, an embossed conduit is attached to a print pattern having a wood grain pattern formed on a base material, a print protective layer for protecting the print layer, and a thermosetting resin film or a thermoplastic resin film. A woodgrain decorative board comprising a patterned resin layer in which only the conduit portion is filled with a wiping colorant and a transparent resin layer covering the patterned resin layer is disclosed.
According to this, since the embossed conduit is formed and only the conduit portion is filled with the wiping colorant, the pattern resin layer is provided with irregularities, and a realistic wood pattern expression closer to real wood is obtained. Yes.
However, since it is necessary to match the grain pattern of the printed layer with the embossed conduit formed later, it is difficult to mold, and a step of filling the formed conduit with a wiping colorant is also necessary. Therefore, it cannot be said that the manufacturing process is simple, and it is not suitable for the current manufacturing situation which tends to produce a variety of products in small quantities.

Further, the following cited document 3 is not an example of a decorative material with a woodgrain pattern, but when a designable building material is manufactured by inkjet coating, a printing surface forming paint is applied, and a reactive compound is added. A method for producing a designable building material is disclosed in which a clear ink containing a reactive compound that reacts with a reactive compound contained in a colored ink is ejected after the contained colored ink (color ink) is ejected.
According to this, when the clear ink is ejected after the colored ink is ejected, the two inks react and the colored ink adheres firmly on the surface to be printed, and bleeding of the colored ink can be prevented.
However, as in the case of Patent Document 1 described above, since clear ink is applied to the entire surface, it is difficult to express the luster and shimmer peculiar to wood grain.

  As described above, in a general manufacturing method, it is very time-consuming to change the gloss of the surface according to the pattern of the wood grain. It is desirable to be able to express real wood grain patterns. In recent years, there has been a tendency for high-mix low-volume production to be demanded in the market, and it is necessary to respond to this.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a wood-tone decorative material capable of easily expressing a genuine wood grain pattern and a method for producing the same.

In order to achieve the above object, the woodgrain decorative material according to the present invention has a woodgrain pattern inkjet-coated on the surface of a substrate, and the surface is inkjet-coated with color ink on the surface. In addition, clear ink is inkjet-coated on the wood grain pattern conduit portion, and the plurality of ink ejection openings from which the clear ink is ejected are set so that the diameters of the ejected ink droplets are different from each other. It is characterized in that clear inks of different sizes are ink-jet painted .
Further, the woodgrain decorative material according to the present invention is a material in which a wood grain pattern is inkjet-coated on the surface of a base material, and the surface is coated with a wood grain pattern by color ink, Clear ink is painted on the portion by inkjet, and clear ink that is different in gloss from the clear ink painted on the portion of the conduit is inkjet coated on the portion other than the conduit, and the clear ink is discharged. The plurality of ink ejection openings are set so that the diameters of the ejected ink droplets are different, and clear inks having different droplet sizes are inkjet-coated .

In the present invention, a plurality of clear inks having different glossiness may be inkjet-coated on the conduit portion. The clear ink may contain particles that reflect light, and examples of the particles to be included include mica particles and metallic particles.
As a method for producing a woodgrain decorative material in which a wood grain pattern is inkjet-coated on the surface of the base material, a color ink is used to inkjet paint the wood grain pattern on the surface, and then a clear ink is inkjet-painted on the portion of the conduit portion . The plurality of ink ejection openings from which the clear ink is ejected are set so that the diameters of the ejected ink droplets are different, and can be manufactured by applying the clear ink by inkjet coating with different droplet sizes .

According to the woodgrain decorative material of the present invention , the clear ink is applied to the portion of the conduit portion of the woodgrain pattern, so that there is a difference in gloss and shine between the portion of the conduit portion and the portion excluding the conduit portion. As a result, the luster and shine that make real woody feel are expressed, so that the wood grain expression closer to the real thing can be achieved. In other words, according to the woodgrain decorative material, the glossiness, hardness, and glossiness that a genuine solid board material gives are expressed, so when used as an interior material or exterior material It is possible to have a high-class feeling as if a genuine solid plate material is used.

  In addition, clear ink is painted on the conduit part of the wood grain pattern by ink-jet painting, and clear ink different in gloss from the clear ink painted on the part of the conduit part is ink-jet painted on the part other than the conduit part. However, the same effect as described above can be realized. That is, according to this, the surface of the conduit portion has a luster different from that of other portions, and a realistic wood texture closer to the real wood can be expressed. Therefore, since the gloss of the portion of the conduit portion and the portion excluding the conduit portion is different, it is possible to obtain a wood-tone decorative material that expresses real luster and shine when the entire wood-tone decorative material is viewed.

Furthermore, if a plurality of clear inks having different glossiness are applied to the conduit portion by inkjet coating, the expressiveness of gloss and shine in the conduit portion is improved.
In addition, if particles that reflect light such as mica particles and metallic particles are included in the clear ink, the light is reflected or scattered when it strikes the wood-tone decorative material. , The shimmering expression can be made more realistic.

And according to the method for producing a woodgrain decorative material of the present invention, if clear ink is applied to the part of the conduit portion of the woodgrain pattern, it is possible to express the gloss that makes real woody feel. It is possible to simulate the near real shine. In addition, since there is no step of embossing the base material, it can be easily applied at low cost, and a manufacturing method suitable for high-mix low-volume production can be configured.

Schematic explanatory diagram for explaining the third embodiment of the woodgrain decorative material, FIG. 8 is used for manufacturing the woodgrain cosmetic material according to the third embodiment Is a block diagram showing an example of a coating apparatus.
In addition, all these drawings have shown typically for description.

First, a first embodiment will be described with reference to FIGS.
The wood-tone decorative material 1 has a substantially rectangular parallelepiped shape, and the surface 12a of the base material 12 is ink-jet painted with a color ink on the surface 12a. In order to express the wood-grain pattern more realistically, an annual ring and a conduit are represented. A clear ink is applied by ink-jet coating to the conduit portion 1a. As the base material 12, a wood-based substrate such as a laminated material, plywood, particle board, or wood fiber board is used.
As shown in FIGS. 1 and 3, the painting apparatus A includes a CPU 20a for controlling each means, an operation means 20b for performing various operations, a storage means 20c for storing a control program or pattern data of a wood grain pattern to be painted, and the like. The control unit 20 is provided. The coating apparatus A also includes an inkjet coating unit including a transport unit 60 that transports the substrate 12 placed thereon, a first ink head 70 on which color ink is mounted, and a second ink head 80 on which clear ink is mounted. 40.

The base material 12 to be coated is conveyed in the direction indicated by the white arrow by a conveying means 60 such as a roller conveyor 2 configured on the base 3, and the conveying means 60 ejects ink droplets by the inkjet coating unit 40. It is linked with the operation. Then, the surface coating of the base material 12 is performed by ejecting ink droplets of color ink from the ink discharge ports of the first ink head 70 disposed above the coating surface of the base material 12. The driving method of the first ink head 70 and the second ink head 80 is not particularly limited, and a known method can be applied as appropriate. Examples thereof include a piezo method and a valve method.
In FIG. 1, 30 is an apparatus main body provided adjacent to the base 3, and 50 is a nozzle arm that is connected to the apparatus main body 30 and supports the inkjet coating unit 40 (first ink head 70, second ink head 80). It is.
The first ink head 70 includes four ink heads that eject color inks, and is configured to eject ink droplets of black, yellow, magenta, and cyan.
The second ink head 80 includes three ink nozzles 80a so that the clear ink can be applied quickly according to the shape such as the thickness of the portion 1a of the conduit portion printed by inkjet coating.
Therefore, for example, when painting a wide conduit portion 1a as shown in the Y portion of FIG. 2, clear ink is ejected from the three ink nozzles 80a and printed on both sides of the Y portion of FIG. When painting the narrow conduit portion 1a, the clear ink is ejected from only one ink nozzle 80a.
The configuration of the second ink head 80 that ejects the clear ink is not limited to the configuration that moves in the width direction (see the arrow direction in FIG. 1) as shown in FIG. It is good also as what was comprised in the whole width direction. Further, the number of ink nozzles 80a constituting the second ink head 80 is not limited to three.

FIG. 2 is a cross-sectional view taken along the line X-X in FIG. 1, in order to explain the conduit portion expressed by inkjet coating of the surface 12 a of the substrate 12 and the portion to be coated with clear ink. Moreover, the top view of the woodgrain decorative board 1 is also shown.
Below, the manufacturing method of the woodgrain decorative board 1 in 1st Embodiment is demonstrated, referring FIG.
First, the base material 12 that has been subjected to the pretreatment process is transported to a predetermined position by the transport means 60. The pretreatment method before ink-jet coating is not particularly limited, but a white ink receiving layer (not shown) may be applied to improve ink fixing and color development.
When a detection sensor (not shown) or the like detects that the base material 12 has arrived at a predetermined position, the ink discharge of the first ink head 70 is based on the grain pattern data stored in the storage unit 20c of the control unit 20. Color ink is ejected from the outlet.
Then, a high-quality wood grain pattern is printed on the surface 12a of the substrate 12 by inkjet coating, and a conduit portion peculiar to the wood grain pattern such as an annual ring and a conduit is expressed.
In the figure, reference numeral 11 denotes a color print layer, and 10 denotes a clear print layer.

Next, after a wood grain pattern is inkjet-coated with color ink on the surface 12 a of the base material 12, a second ink head 80 is disposed toward the portion 1 a of the conduit section of the grain pattern, and the ink discharge port of the second ink head 80 To discharge clear ink. That is, after the color printing layer 11 is formed by inkjet painting with the first ink head 70, the clear printing layer 10 is subsequently formed by inkjet painting with the second ink head 80 so as to follow this. At this time, the clear ink is not applied to the entire surface 12a of the base material 12, but is applied by ink jet targeting the conduit portion 1a as shown in the enlarged view of the Y portion in FIG. Only the portion corresponding to is slightly convex from the color printing layer 11.
If the color ink and the clear ink to be painted are different in gloss, it is possible to express gloss and shine that make a real woody feel even more.

Then, if necessary, the upper surface of the clear printing layer 10 is covered with a surface layer (not shown) made of a transparent urethane resin or the like as a post-processing step and dried to obtain the woodgrain decorative material 1. At this time, as the resin for forming the surface layer, a resin that does not erase the difference in gloss between the portion 1a of the conduit portion and the portion 1b excluding the conduit portion is used. Thereby, it can be set as the grain-like decorative material 1 excellent in water resistance or weather resistance while expressing luster and shine that make real woody feel.
Note that the configurations of the first ink head 70 and the second ink head 80 are not limited to those shown in the figure, and may be integrated as a unit. This is desirable because it can be applied to the ink with a time difference, and the process of applying the clear ink is surely performed after the color ink. Moreover, it does not specifically limit about a pre-processing process and a post-processing process, A well-known process is employ | adopted.

Thus, the clear ink (clear printing layer 10) that is inkjet-coated on the portion 1a of the conduit portion of the wood grain pattern creates a hard feeling peculiar to the conduit portion, and expresses luster and shine that make real wood feel, It can be assumed that the wood grain expression closer to the real thing was made.
Further, since the wood grain pattern is expressed by ink-jet coating based on the pattern data stored in the control unit 20, a plate surface is not required unlike gravure printing, and a variety of wood grain is provided on the surface 12a of the substrate 12 at low cost. A pattern can be printed. Therefore, it is possible to deal with a variety of small-quantity production.

The clear ink to be applied to the conduit portion 1a may be the same glossy clear ink, but may be a plurality of clear inks having different glossiness, and may be a liquid ejected from the ink nozzle 80a. Clear ink may be painted with different droplet sizes.
4A and 4B are explanatory diagrams for explaining another example of the first embodiment.
In FIG. 4A, clear inks having different glossiness are put into each of the three ink nozzles 80a.
The diameters of the ink droplets 10a ejected from the ink ejection port 80b formed in the ink nozzle 80a are provided to be the same.
There is no limitation on how the ink nozzles 80a into which clear inks having different glossiness are put are placed, but for example, a clear ink having a high gloss value is put into the ink nozzles 80a placed in the center. The clear inks having different glossiness may be put into the ink nozzles 80a arranged on both sides.
Here, gloss refers to the gloss (shininess, degree of light reflection) that occurs when ink-jet coating is applied and dried, and this gloss can be measured numerically as a gloss value by a gloss meter. The feeling can be adjusted as appropriate by known preparations of resin materials, pigments, solvents and the like contained in the clear ink.

The clear ink is controlled to be ejected in accordance with the shape of the conduit portion expressed on the base 12 as described above. When coating the wide conduit portion 1a as shown by the Y portion in FIG. When clear ink is ejected from the three ink nozzles 80a and the narrow conduit portion 1a printed on both sides of the Y portion in FIG. 2 is painted, clearing is performed only from the central ink nozzle 80a. Ink is ejected.
At this time, since the glosses of the clear inks discharged from the three ink nozzles 80a are different from each other, the expression of the wood grain pattern becomes a realistic expression closer to the real wood. In particular, since a plurality of clear print layers 10 having different glosses are formed on the color print layer 11 on which the conduit portion 1a representing the annual ring and the wide conduit portion 1a are printed, the expressive power is improved. .
In addition, according to various trial manufactures by the inventor, it is known that a realistic wood texture can be obtained by applying a plurality of clear inks having different glosses.

The example shown in FIG. 4B differs from the example shown in FIG. 4A in that the diameter of the ink droplet 10a ejected from the ink ejection port 80b formed in the ink nozzle 80a is set to be different. . The clear inks that are put into the ink nozzles 80a may have the same gloss, or clear inks that have different glosses.
As shown in FIG. 4 (b), clear ink is applied by ink-jet coating onto the printed conduit portion 1a of the color print layer 11 formed on the surface 12a of the substrate 12, and the clear print layer 10 (FIG. 2). Reference).
Thus, even if the droplet sizes are varied, the expression of the wood grain pattern can be improved.
The arrangement of the ink nozzles 80a having different droplet sizes to be ejected is not limited. For example, when the portion 1a of the conduit portion shown in the Y portion of FIG. ), The droplet size ejected from the central ink nozzle 80a may be set large, and the droplet sizes ejected from the ink nozzles 80a on both sides may be made different.
According to this, since the ink droplet 10a having a large droplet is inkjet-painted at the center of the conduit portion 1a, the gloss is different from that of the other conduit portion 1a, and a more genuine woody material. It is possible to express a realistic wood texture close to.
Depending on the components of the clear ink used, the smaller the droplet size, the better the gloss can be expressed. In such a case, in order to express a realistic wood texture, an ink nozzle 80a having a small droplet size may be disposed immediately above the portion 1a of the conduit portion to perform ink jet painting.

The clear ink that is painted on the portion 1a of the conduit portion may contain particles that reflect light in order to further enhance the expressive power.
FIG. 5 is an explanatory diagram for explaining still another example of the first embodiment, and is the same diagram as FIG. 2. Portions common to the above-described embodiment are denoted by the same reference numerals, and description of the common portions is omitted.
In the example shown here, particles that reflect light are contained in the clear ink that is inkjet-coated in the portion 1a of the conduit portion. The particles to be included in the clear ink are not particularly limited as long as they reflect light. For example, mica particles 10b and metallic particles 10c can be included. When the mica particles 10b are included, a pearly luster can be produced, and when the metallic particles 10c (for example, fine aluminum particles called aluminum flakes) are included, the appearance varies depending on the viewing angle. The direction changes, and you can create a sparkling luster.
Therefore, it is possible to express the gloss and shine of the conduit that cannot be expressed only with colorless and transparent clear ink, and the light is reflected or scattered when it hits the above particles. It will be real.
The particle size of the particles is not particularly limited, but may be any size as long as it does not clog the nozzle outlet 80b of the ink nozzle 80a. For example, particles having a size of 0.1 μm to 10.0 μm can be included in the clear ink. .

  As shown in the Z-part enlarged view of FIG. 5, the clear ink may contain mica particles 10b and metallic particles 10c, or may contain any one of mica particles 10b and metallic particles 10c. When three ink nozzles 80a are configured, a clear ink containing mica particles 10b, a clear ink containing metallic particles 10c, a clear ink containing mica particles 10b and metallic particles 10c, and The clear ink to be introduced into the ink nozzle 80a may be different. Further, the gloss of the clear ink may be varied by adjusting the amount of particles added. Further, as shown in the example of FIG. 4A, if the clear ink itself has a different gloss, the particles are contained as described above, or the droplet size for discharging the clear ink containing the particles is changed. A rich variety of glossy and shiny expressions expressed with clear ink.

Next, a second embodiment will be described with reference to FIG.
Parts common to the first embodiment are denoted by the same reference numerals, and description of common parts is omitted.
The woodgrain decorative material 1 shown in the second embodiment is obtained by inkjet printing a wood grain pattern on the surface 12a of the base material 12, and the surface 12a is inkjet painted with a wood grain pattern by color ink. The clear ink is ink-jet painted on the portion 1b except for the conduit portion of the handle.
As shown in FIG. 6, by applying clear ink to the portion 1b excluding the conduit portion, even if the gloss is different between the portion 1a of the conduit portion and the portion 1b excluding the conduit portion, the glossy feeling that makes real woody feel. A hard feeling can be expressed.

Here, the configuration of the second ink head 80 into which clear ink has been introduced is not shown, but the same configuration as in the first embodiment can be used.
The example of the first embodiment can also be applied to the clear ink to be applied. Therefore, the clear ink to be supplied to the ink nozzles 80a may be the same glossy clear ink, or a plurality of clear inks having different glosses may be used as in the example shown in FIG. Further, the clear ink may be applied with different droplet sizes ejected from the ink nozzles 80a as in the example shown in FIG. 4B, or mica particles may be applied to the clear ink as in the example shown in FIG. Particles that reflect light, such as metallic particles, may be included.

Next, a third embodiment will be described with reference to FIGS.
Parts common to the first embodiment are denoted by the same reference numerals, and description of common parts is omitted.
The woodgrain decorative material 1 shown in the third embodiment is obtained by inkjetting a wood grain pattern on the surface 12a of the base material 12, and the surface 12a is inkjet painted with a wood grain pattern by color ink. The conduit portion 1a is coated with clear ink by inkjet, and the portion 1b excluding the conduit portion is coated with clear ink having a gloss different from that of the clear ink coated on the conduit portion 1a.
Therefore, the coating apparatus A according to the third embodiment is further provided with a third ink head 90 into which clear ink is introduced, as shown in FIG.
As shown in Fig. 7, the glossy and hard feeling that makes you feel real woody is expressed by making the gloss of the clear ink painted on the portion 1a of the conduit portion different from the gloss of the clear ink painted on the portion 1b excluding the conduit portion. can do.
Also, according to this, the clear print layer 10 is formed on the entire upper surface of the color print layer 11, so that it can also serve as a protective layer for the color print layer 11.

Here, how many ink nozzles are configured with respect to the second ink head 80 and the third ink head 90 into which clear ink has been introduced is not shown, but the second ink head 80 according to the first embodiment A similar configuration can be used.
The clear ink coating process is not particularly limited, but after the portion 1a of the conduit portion is coated with the second ink head 80, the portion 1b excluding the conduit portion is coated with the third ink head 90. Good. Of course, after the portion 1b excluding the conduit portion is first coated with the second ink head 80, the portion 1a of the conduit portion may be painted with the third ink head 90.
The second ink head 80 and the third ink head 90 may be integrated into a unit, but by separating them as shown in the example, clear inks with different gloss can be reliably applied over time. become.
Different clear inks are supplied to the second ink nozzle 80 and the third ink nozzle 90, respectively. Different clear inks may have different gloss values, or they may have different gloss values, and the same glossy clear ink is prepared, and one clear ink contains particles that reflect light such as mica particles and metallic particles.
