Description

  The present invention relates to a door material made of a composite decorative board partially using a transparent resin plate, and more particularly to a method for forming a picture layer configured in close contact with a transparent resin plate.

  In recent years, a system kitchen using a high-gloss composite decorative board with a deep pattern layer that can be seen through the transparent resin plate as a door material has been highlighted as a door to improve the design of the door material. Have been bathed. When the system kitchen uses a plurality of door materials or drawer face materials, the design has many monocolor finishes, a pattern layer is provided by printing or painting, and partially wood-grained door materials are used There is also.

  In the present invention, a transparent acrylic resin plate is used as the transparent resin plate, but the back surface of the transparent acrylic resin plate has a slight difference for each sheet, but the wood grain pattern without any sense of incongruity as a whole is handmade. This is a composite decorative board. When applying a grain pattern to a transparent acrylic resin plate, normal printing or printing film lamination, transfer printing, etc. are adopted, but if a plate for printing is required and the same pattern is produced in large quantities Although it is good, it is not suitable for door materials or face materials of system kitchens. Since a one-point or a small amount of wood-tone door is required, production by the conventional printing method requires an expensive printing plate, and mass production is indispensable to amortize it. For such applications, small-scale production is possible without using an expensive printing plate, and even if each pattern is different, it will be an aggregate of similar designs when it becomes an aggregate, and there is no sense of incongruity A decorative board was required.

Conventionally, the surface of the unusual ceramics extrusion material 40 shown in FIG. Apply a urethane or epoxy sealer and apply acrylic urethane enamel paint as a base coat with a ground color that matches the grain of the wood you want to draw, then dry and blur the light color of the wood with a soft brush. If necessary, after partially wiping with a raw cloth and drying, the dark part of the grain is drawn with a hard brush, a grooved rubber plate or the like while visually observing. After the painted part is dried, acrylic urethane clear is applied by spraying to obtain an extruded material with a grain-like shape. The obtained wood grain pattern is different from the wood grain of natural trees by the printing method, but gives the same impression as the wood grain. In the present invention, this is described as wood grain. Individually, the pattern is different, but there is a woodgrain pattern that does not feel strange when viewed as an aggregate. This method is a pattern that is not reproducible when viewed individually without using an expensive printing plate, but a design that does not feel uncomfortable when viewed in an aggregate is obtained. Therefore, it gives a big hint when creating a woodgrain composite decorative board used for the door or face material of a system kitchen.
Japanese Patent Laid-Open No. 2007-152087

  Provided is a composite decorative board having a quality that can be used as a door material or a face material of a high-gloss and deep wood grain system kitchen. Provide woodgrain design without using expensive printing plates. An object is to provide a painting method and a painting tool for applying a design that has different patterns, but each pattern is a little different when assembled, and does not give a sense of incongruity. It has the same performance as a mono-colored door and can be produced in small quantities at a low cost. Even if it does not have the same finish as printed on each sheet, even if multiple sheets are used as a door on the same surface It is to provide a door material or a face material without a sense of incongruity.

  First, a transparent acrylic resin plate is used as an example of a transparent resin plate, and a transparent clear layer is formed on one surface of the resin plate by a spray coating machine. At this time, a color may be cleared by adding a pigment or the like to the clear paint. Color beads, mica powder and pearl pigments can be added to match the wood grain design. These clear layers have the effect of making the wood grain design to be painted more effective, the effect of improving the adhesion to the wood grain paint and the heat resistance when it is made into a door or face material. In order to stabilize, a clear layer with good adhesion is provided between the acrylic resin plate and the craft design coating layer simulating a wood grain. The craft design coating layer imitating the wood grain is a transparent clear coating layer, a dark wood coating layer, a light coating layer for coloring between the grain, and a base color coating reflecting the design background Formed in layers. Since the craft design coating layer is a design that is visually recognized through a transparent acrylic resin plate, a transparent clear layer is provided on the transparent acrylic resin plate, and then dark portions such as annual rings, conduits, and nodes are painted, and A light color portion having a wide range is painted, and then a color tone that dominates the entire surface of the wood grain tone is painted, so that a preferable grain is expressed when viewed through the transparent acrylic resin plate. As a transparent resin board, it is not limited to an acrylic resin board, If it has transparency, such as a polycarbonate, a polystyrene, and ADC, it can utilize. In order to improve the scratch resistance, a hard coat layer may be provided and used. A urethane primer or the like can be used to improve adhesion.

  The dark wood grain coating layer corresponds to the dark part of the wood using a semi-rigid brush or bamboo brush, or a jig provided with a plate with an arc-shaped groove on the surface of rubber or plastic. Paint the pattern. The dark part of the wood is the annual ring part, which corresponds to the grain or the mesh.

  Next, a soft brush or pad is used to paint the light-grained portion of the wood grain and color the space between the wood. In some cases, a portion of the paint may be wiped off with a soft cloth immediately after painting. Painting with these brushes is done only in one direction.

  Next, paint the base color with a paint that reflects the background of the entire design because it appears to overlap with the light-colored part that colors between the dark-grained part and the grain of the grain that was previously painted. Spray and dry the entire surface with a spray coater.

  The craft design coating layer that imitates the grain that can be seen through the transparent acrylic resin plate by applying the clear layer, coating of the dark wood grain portion, painting of the thin wood tone portion and base coat spray coating on the transparent acrylic resin plate as described above A high gloss and deep pattern can be realized without using an expensive printing plate.

  When painting the above wood grain part, use the guide bar on the practice board in advance to determine the preferred height of the brush, determine the color of each paint, determine the brush application speed, etc. After that, multiple sheets are created by painting. Individual lines vary in thickness, wetness, etc., but when a plurality of painted plates are combined and viewed as an aggregate, a transparent resin plate with a wood grain tone that has no discomfort is obtained as a pattern. It is done.

  As described above, the acrylic resin plate-like body provided with the craft design coating layer is bonded to the wooden board material through the adhesive layer using the adhesive with the base color coating layer side as the bonding surface. The other surface of the plate material is formed by applying an adhesion adjusting layer on a resin plate having a linear expansion coefficient equivalent to that of the acrylic resin plate, and is similarly bonded through the adhesive layer to obtain a composite decorative plate. As the resin plate, a white ABS resin plate is preferably used. The adhesion adjusting layer is a coating layer having the same physical properties as the above-mentioned craft design coating layer, and improves the adhesion and makes the physical properties of each layer in close contact with both surfaces of the core material uniform to prevent warpage.

  When the composite decorative board obtained in the present invention was used partially on a plurality of door materials or a surface material such as a drawer of the system kitchen, a system kitchen having a grain-like design with no sense of incongruity was obtained. Since a printing plate is not used, it can be applied to a small amount of production, is highly economical, and can be used in various fields as a decorative member for building materials and furniture. The feature of the present invention resides in a transparent resin plate having a craft design coating layer, and the use of the transparent resin plate alone as a decorative plate is also included in the present invention.

  An acrylic resin plate having the same thickness, gloss and transparency is selected as the base sheet in order to make the gloss and smoothness the same as other door materials used in the system kitchen. Next, the wood grain to be formed is determined to be a hard brush shown in FIG. 4 or a rubber plate shown in FIG. Further, select whether the wood grain color is clear or transparent. For patterning, the thickness of the line is determined by the degree of pressing of the brush or the like. By moving the brush along the guide bar and further moving the brush with the guide rod on the guide bar as shown in FIG. In this example, the pattern is not directly visible and can be adjusted by hand like the patterning seen from the surface, but the final base color is painted and the pattern is completed, and the whole image can only be seen through the acrylic resin plate. For this reason, painting cannot be performed while adjusting in the middle, and preliminary painting is performed so that patterning can be performed under the same conditions in advance.

  First, an outline of the system kitchen is shown in FIG. Reference numeral 30 is a front view of the system kitchen, and a composite decorative board is used as a plurality of door materials or drawer face materials. 31 is a composite decorative board using a mirror-finished acrylic resin plate having a single-color decorative layer, and 1 is a woodgrain composite decorative board of the present invention. As other facilities, 32 is an oven, 33 is a gas stove, 34 is a tile wall, and 35 is a range hood.

  Next, the construction and manufacturing procedure of the woodgrain composite decorative board 1 of the present invention will be described. The structure of the woodgrain composite decorative board 1 is shown as a schematic cross-sectional view in FIG. Reference numeral 2 denotes a wood-based plate material using a particle board having a thickness of 12 to 15 mm. Reference numeral 3 denotes a transparent acrylic resin plate having gloss. Reference numeral 4 denotes a back surface resin plate, which is an opaque resin plate containing a pigment and uses an ABS resin plate having a linear expansion coefficient substantially equal to that of an acrylic resin plate. 5 is a clear paint layer, 6 is a dark color wood grain paint layer that embodies the grain, 7 is a light color paint layer that colors between the wood grain, and 8 is a base color paint layer that represents the color of the entire design. The four layers are combined to form the craft design coating layer 9. The craft design coating layer is in close contact with the transparent acrylic resin plate 3 to form a transparent acrylic resin plate 10. Reference numeral 11 denotes an adhesive layer to which an adhesive is applied, 12 denotes an adhesion adjustment layer that has physical properties equivalent to those of the craft design coating layer, and adjusts adhesion and expansion coefficient, and 13 denotes an adhesive layer to which an adhesive is applied. FIG. 1B is a schematic perspective view of the woodgrain composite decorative board 1, and the coating layers are omitted because they are combined and do not show a remarkable thickness. The craft design coating layer 9 shows a unique color tone by overlapping the hues of the coating layers constituting the craft design coating layer 9 and is visually recognized through a transparent acrylic resin plate. The transparent acrylic resin plate has a total light transmission rate of 92% and a refractive index of 1.49. It is in the category of the highest transmittance among resin plates, and its refractive index is much higher than that of air, so the craft design appears to be lifted up, giving depth to the color tone.

The transparent acrylic resin plate 3 has a thickness of 2 mm and a size of 910 mm × 910 mm (trade name: Acrylite S manufactured by Mitsubishi Rayon). The clear coating layer 5 paint is an acrylic urethane-based clear paint (trade name: Refine 2K, manufactured by Tope Co., Ltd.) with a mixing ratio of 9: 1: 5 as the main agent: curing agent: thinner, and an air spray is used. And apply to one side of the acrylic resin plate. It apply | coated in the ratio of 80 g / m < ² >, put into the shelf, and performed natural drying. The drying time is 12 hours at 20 ° C. As the painting means, a curtain coater, a roll coater, etc. can be used in addition to the spray.

  Next, a grain pattern is formed. The acrylic resin plate 3a having the clear coating layer formed in close contact with the wood grain coating table 15 shown in FIG. Dummy plates 16 having the same thickness are closely fixed to both side ends of the acrylic resin plate to prevent the acrylic resin plate from moving. As shown in FIG. 4, the brush 17 is provided with a guide rod 17a, and the tip of the hair tip 17b containing the paint is pruned so as to make the length of the hair longer or shorter. The guide bar 17a is slid while abutting on a guide bar 18 placed on the dummy plate to make the pressing force of the brush constant. Using a brush 17 having a hard tip with a guide bar containing dark paint, and setting the conditions for painting with another practice board, it is moved in parallel along the guide bar 18 and linearly grained. Paint the pattern. The dummy plate 16 has a length of about 100 mm with respect to the coating direction, and the acrylic resin plate is coated by continuously adjusting the pressing force of the brush while passing through the dummy plate 16. When the first coating is completed, the guide bar is moved in parallel by the length corresponding to the coating width, and the wood coating is performed again in the same manner. After the entire acrylic plate was painted, it was naturally dried by placing it on a shelf at 20 ° C. for 4 hours. In the case of heating, a drying condition of 60 ° C. to 5 minutes may be used. The dark paint is acrylic urethane enamel and is adjusted at a ratio of main agent: curing agent: thinner = 9: 1: 3.

  Next, a light-colored coating layer for coloring between the grain patterns is formed. A light-colored paint that matches the hue of the grain is included in the soft brush, and the brush 17 with a guide bar is placed on the guide bar, and the paint is applied straight while keeping the pressure constant. Make the shades of colors by increasing or decreasing the size of the painted layer. You may make a part to wipe off with a raw cloth. Record the coating level, wiping level, and guide bar height. Dry at 20 ° C for 4 hours or 60 ° C for 5 minutes. The paint of the light-colored coating layer is acrylic urethane enamel, and is adjusted at a ratio of main agent: curing agent: thinner = 9: 1: 9.

After drying the light-colored coating layer, a base color coating layer for adjusting the color tone of the design surface is formed. The paint was acrylic urethane enamel (trade name: Refine 2K, manufactured by Toupe), which was adjusted at a ratio of main agent: curing agent: thinner = 9: 1: 5 and spray-coated at a rate of 120 g / m ² . Drying was carried out on a shelf and naturally dried at 20 ° C. for 12 hours. As a result, the clear coating layer 5, the dark color grain coating layer 6, the single color coating layer 7 and the base color coating layer 8 become an integral laminate, and the craft design coating layer 9 is formed. Together, the transparent acrylic resin plate 10 is completed.

  After drying, it is reversed and the pattern of the craft design is confirmed through the acrylic resin, and the pressure and viscosity of the brush are adjusted again for the coating part outside the assumed range to grasp the desired condition. Create an overall picture with the practice board, grasp the painting conditions of each part, and start painting work when all the conditions are met. This condition is not for making exactly the same grain, but for making it easy to reproduce the image of the grain.

  The base color coating layer 8 of the acrylic resin plate 10 and the wood board 2 are bonded via an adhesive layer 11 using an adhesive. The adhesion adjusting layer 12 is applied and formed on one side of the back surface resin plate 4 on the other surface of the wood-based board material 2 and is bonded to the wood-based board material 2 via the adhesive layer 13 after drying, thereby completing the woodgrain composite decorative board 1. . The adhesion adjusting layer is a coating layer having physical properties equivalent to those of the craft design coating layer. In this embodiment, an acrylic urethane enamel paint is used. A white ABS resin containing a pigment having a thickness of 2 mm was used as the back resin plate. It has a linear expansion coefficient almost equal to that of an acrylic resin plate and prevents warping of the composite plate due to temperature changes.

  Although the wood grain pattern that can be seen through the acrylic resin plate is different from the one that faithfully reproduces the grain of natural wood, a grain-like design that resembles a wood grain was obtained. When the composite decorative board 1 using the acrylic resin plate body integrally formed with the craft design coating layer obtained above is seen next to the other monocolor finish face material 31, the gloss and smoothness are as follows. A system kitchen with the same and uncomfortable feeling was obtained.

  Leave the acrylic resin plate clear painted on the wood grain coating table 15 shown in FIG. 5, and apply a paint corresponding to the dark wood part of the color specified by the practice board with a soft brush or spray coating machine, Immediately, the jig 19 attached with the rubber plate shown in FIG. 3 was slid in the direction of the arrow to scrape off the paint. FIG. 3A is a perspective view of the rubber plate jig 19 for operating the plate mounting table 19a formed with a curved surface C in part, the plate 20 attached to the curved surface C, and the jig. It consists of a handle 19b. The printing plate 20 is shown in a perspective view in FIG. The material of the plate 21 is a rubber or resin plate. Grooves 22 are formed in a substantially concentric shape on one side to form an uneven plate, which is bonded to the curved surface C to form the jig 19. In this example, a rubber plate was used. When the printing plate 20 is brought into contact with the coating surface and is slid in the direction of the arrow in principle, the paint moves along the groove 22 to the center of the printing plate. The scraped paint stays in the groove and the paint that has not been scraped is returned to the painted surface. If the angle of the handle 19b with respect to the painted surface is changed while moving in the direction of the arrow, the convex portion that forms a groove that strongly contacts the painted surface will scrape the paint, but the portion from the outside outside the center will be returned to the painted surface. The returned part will draw an elliptical stripe, and the paint will form a plate pattern. An example is shown in the photograph of FIG. It is possible to freely change the grain pattern by tilting or raising the handle of the rubber plate jig in the sliding direction to change the way of application. Adjust how the grain appears with your eyes. When the wood grain pattern is completed, it is dried, and then a light color paint is applied to the entire surface to color between the wood grain, and after drying, the base color is applied to complete the craft design coating layer.

  In order to obtain a dark wood grain tone, instead of the acrylic urethane-based clear paint in Example 1, an acrylic urethane-based clear in which a coloring material containing black pigment, yellow pigment, and red pigment is appropriately blended with acrylic urethane-based clear is used. By spray coating, an acrylic resin plate-like body imitating a dark-colored wood grain was obtained.

  In order to impart luster to the woodgrain pattern seen through the transparent acrylic resin plate, 0.1% to mica powder is added to the acrylic urethane clear paint forming the clear coating layer 5 shown in FIG. An acrylic resin plate having a glittering clear coating layer was obtained by spray-coating clear mixed with 5%. Thereafter, a composite decorative board was completed through the same steps as in Example 1. This glittering wood-tone acrylic resin plate is a design not found in natural wood, but may be necessary to match the design of the surrounding kitchen door. Similarly, it is possible to mix a powder that expresses a pearl design into acrylic urethane clear.

  It is effective as a panel for a part to be used in a small amount as a door material of a system kitchen, a drawer face material, or a panel for interior decoration.
