In the present embodiment, a wood board material 10 constituting the wood decorative board 1 is formed by laminating a single board 12 as a natural wood constituting a surface layer portion 12 on the surface of a base material 11 as shown in FIG. It has been configured.
Examples of the base material 11 include wood-based materials such as plywood and wood laminates such as LVL (single-plate laminate), wood boards such as particle boards, and wood fiber boards such as insulation boards and MDF (medium density fiber boards). It may be formed. Further, the base material 11 is formed from a wood powder / plastic composite material (WPC) in which a synthetic resin material contains wood powder, an inorganic filler, a compatibilizing agent, a colorant and the like in a predetermined content ratio. Also good. Further, the base material 11 may have a multilayer structure in which plate materials made of these various materials are laminated.

The veneer 12 may be formed by thinly slicing natural wood (named wood). The single plate 12 may be a so-called protruding plate having a thickness dimension of about 100 μm to 0.25 mm, or may be a thick single plate thicker than this. The thickness dimension of the single plate 12 may be set to, for example, about 0.2 mm to 2.0 mm from the viewpoints of workability of float processing, cost, and the like. Examples of natural wood constituting the veneer 12 include beech, oak, cedar, mekaba, beach, oak, teak, hard maple, cherry, walnut, white ash, mahogany, and other various tree species. Further, the natural wood constituting the veneer 12 is made of a tree species in which the hardness difference (density difference) between the spring wood part (early wood part) 13 and the autumn wood part (late wood part) 15 is relatively large. Also good.
In addition, the veneer 12 may be obtained by abutting and bonding a plurality of treated woods to form a laminated material and slicing the laminated material.

Further, in the method for manufacturing a wooden decorative board according to the present embodiment, at least the surface layer portion (single plate) 12 is made of natural wood, and is provided with a concave portion 14 and a convex portion 16 on the surface by being floated. A step of applying the dark paint 17 to the surface including the bottom side of the concave portion 14 of the wood board 10 is provided. The manufacturing method further includes a step of removing the dark color paint 17 applied to the surface side of the convex portion 16 so that the dark color paint 17 applied to the bottom surface side of the concave portion 14 remains. The manufacturing method further includes a step of applying low gloss paints 18 and 19 to at least the bottom surface side of the concave portion 14. That is, the manufacturing method includes a step of forming a dark and low gloss coating layer 20 on the bottom surface side of the concave portion 14.
Further, in the manufacturing method, a light-color paint that is lighter than the dark-color paint 17 and a high-gloss paint (light-color / high-gloss paint 21) that is higher in gloss than the low-gloss paint are not applied to the bottom surface side of the concave portion 14. A step of applying to the surface side of the convex portion 16 is provided. That is, the manufacturing method includes a step of forming a light-colored and high-gloss coating layer 22 on the surface side of the convex portion 16. Here, the bottom surface side of the concave portion 14 constituting the surface of the wood board 10 may include at least the bottom surface of the concave portion 14 and a surface including the inner surface of the concave portion 14 in the vicinity of the bottom surface. Moreover, the surface side of the convex part 16 which comprises the surface of the wooden board | plate material 10 contains at least the convex front end surface (top surface) of the convex part 16, and the surface containing the outer side surface of the convex part 16 of the convex front end surface vicinity part. It is good.

Hereinafter, an example of a specific process of the manufacturing method will be described.
The manufacturing method may include a stacking step of stacking the single plate 12 on the base material 11 to produce the wood board 10. Moreover, it is good also as a thing provided with the process of forming a real part, a makeup | decoration groove | channel, and a chamfering by cutting etc. in the wooden board | plate material 10. FIG. In addition, you may make it perform these after the float fabrication process mentioned later.
In addition, the manufacturing method may include a float processing step of performing a float processing on the surface of the wooden board 10 so that the concave portions 14 and the convex portions 16 are formed.
As shown in FIG. 1B, this float processing step may be executed by a float processing machine so that an uneven shape is formed on the surface of the wooden board material 10. In the illustrated example, an example is shown in which the float processing is performed by brushing that scrapes (scraps) the surface of the wood board 10 with the float processing machine provided with the brush (wire brush) 2.

  Thereby, as shown in FIG.1 (c), the surface site | part of a comparatively soft site | part (for example, spring material part 13) is scraped off and becomes the recessed part 14, and a comparatively hard site | part (for example, autumn material part 15) The other portions such as) are convex portions 16. In addition, it is good also as an aspect given by sand blasting etc. without being restricted to the aspect which performs a floating process by brushing. Further, the surface polishing treatment may be performed by a sander or the like before the float processing, and a step of appropriately removing wood chips or the like generated by the float processing may be executed.

Next, as shown in FIG. 1 (d) and FIG. 2 (a), dark paint 17 is applied to the surface including the bottom side of the concave portion 14 of the wood board 10 provided with the concave portion 14 and the convex portion 16 on the surface. A dark paint application process is performed. As a result, the dark paint 17 is applied to the entire concave portion 14 and the convex portion 16 constituting the surface of the wooden board 10.
In the present embodiment, the dark paint 17 is applied by a roll coater method. For example, the dark paint 17 may be applied using the sponge roll 3 so that the dark paint 17 is also applied to the bottom side of the concave portion 14. The sponge roll 3 may have an appropriate diameter and hardness so that the dark paint 17 can be applied to the bottom surface side of the concave portion 14. Moreover, this sponge roll 3 is set as the structure rotated in the rotation direction (forward direction) which conveys the wooden board | plate material 10 downstream (forward rotation). In this dark paint coating step, instead of the mode using the sponge roll 3, it may be applied by a roll coater method using a rubber roll or the like, or may be applied by another coater method. Further, the dark paint 17 is a paint containing a colorant such as a pigment or a dye, and may be a paint that is darker than the autumn material portion 15 that is a dark portion of the veneer 12, for example. The dark paint 17 may be adjusted to an appropriate viscosity so as to be applied to the surface including the bottom surface side of the concave portion 14 of the wood board 10.

Then, as shown in FIGS. 1 (d) and 2 (b), the dark paint 17 applied to the surface side of the convex portion 16 is applied so that the dark paint 17 remains on the bottom surface side of the concave portion 14. The removal process to remove is performed. As a result, the dark paint 17 applied to the surface side of the convex portion 16 is removed, and the dark paint 17 remains on the bottom surface side of the concave portion 14. This removal process may be performed immediately after the dark color paint application process so that the penetration of the dark color paint 17 applied in the dark color paint application process into the surface of the convex portion 16 is reduced.
In this embodiment, in this removal process, it is set as the structure which removes the dark color coating material 17 apply | coated to the surface side of the convex part 16 using the removal roll unit 4. FIG. In addition, the removal process includes a removal process using the sponge roll 4c. Further, this removal step includes a removal step using reverse rolls 4a, 4b, 4d and rubber rolls 4e, 4f. That is, the removal process is performed using the removal roll unit 4 including the plurality of rolls 4a, 4b, 4c, 4d, 4e, and 4f. Further, the removing roll unit 4 that executes the removing step is arranged on the downstream side of the sponge roll 3 that executes the dark paint applying step, two reverse rolls 4a and 4b, a sponge roll 4c, and two rubber (natural) rolls 4e, 4f is arranged in this order.

The reverse rolls 4a, 4b, 4d may be metal reverse rolls. As such reverse rolls 4a, 4b, 4d, the surface may be plated with chrome plating or the like. These reverse rolls 4a, 4b, 4d have a rotational direction opposite to the normal direction, and are configured to scrape off and remove the dark paint 17 applied to the surface side of the convex portion 16. . Removal pieces such as a removal blade for removing the dark color paint 17 adhering to the reverse rolls 4a, 4b, and 4d by scraping are brought into contact with the peripheral surfaces of the reverse rolls 4a, 4b, and 4d.
The sponge roll 4c may have an appropriate configuration so as not to remove the dark paint 17 applied to the bottom surface side of the concave portion 14 in the dark paint application step. As the sponge roll 4c, for example, a sponge having a thin radial thickness or a high hardness sponge is used so that it is less likely to be deformed than the sponge roll 3 used in the above-described dark color coating application process. It is good also as what was made the structure which was. The sponge roll 4c has a positive rotation direction.

  The sponge roll 4c may be periodically cleaned or replaced so as to prevent the dark paint 17 adhered (adsorbed) to the sponge roll 4c from being reapplied. For example, the cleaning water is periodically supplied to the sponge roll 4c, and the moisture sucked by the sponge roll 4c is removed by pressing a removal piece such as a removal blade against the peripheral surface of the sponge roll 4c. You may make it wash | clean 4c. Further, in this case, the removed cleaning water may be collected in a tank that supplies the sponge roll 4c and circulated and supplied to the sponge roll 4c, and the cleaning water may be periodically replaced. May be.

The rubber rolls 4e and 4f may be formed by coating rubbers such as ethylene / propylene rubber (EPDM), chloroprene rubber, hyperon rubber, nitrile rubber, silicone rubber, urethane rubber, and butyl rubber on an appropriate roll core. In the illustrated example, the rotation direction of the rubber rolls 4e and 4f is the forward direction, but both or one of them may be the reverse direction.
Moreover, these rubber rolls 4e and 4f may be appropriately configured so as not to remove the dark color paint 17 applied to the bottom surface side of the concave portion 14 like the sponge roll 4c. For example, the rubber constituting these rubber rolls 4e and 4f may be made relatively hard. The rubber hardness (hardness measured using a type A durometer according to JIS K 6253) may be, for example, about 60 to 80 degrees. Further, a removal blade or the like that scrapes and removes the dark color paint 17 adhering to these peripheral surfaces so as to prevent the dark color paint 17 adhering to the rubber rolls 4e and 4f from being reapplied. The removal piece may be provided.
In addition, it is good also as an aspect performed using at least the sponge roll 4c instead of the aspect which performs a removal process using several roll 4a, 4b, 4c, 4d, 4e, 4f in this way.
Moreover, you may make it perform the process of hardening the dark color coating material 17 which remain | survives on the bottom face side of the recessed part 14 suitably after this removal process.

Next, a low-gloss paint application step of applying the low-gloss paints 18 and 19 to at least the bottom surface side of the concave portion 14 is executed. Thus, when the dark paint 17 and the low gloss paints 18 and 19 are cured, a concave bottom surface side coating layer 20 as a dark and low gloss coating layer is formed on the bottom surface side of the concave portion 14. (See FIG. 3B).
In this embodiment, as shown in FIG. 2C, the low gloss paints 18 and 19 are applied by a roll coater method. In addition, after the removing step, clear low-gloss paints 18 and 19 are applied to the surface including the bottom surface side of the concave portion 14 of the wood board 10 as finish coating. Further, an undercoat coating process for applying the undercoat paint 18 as the low gloss paint 18 and an intermediate coat process for applying the intermediate paint 19 as the low gloss paint 19 are executed. These undercoating process and intermediate coating process may be performed using rubber rolls 5 and 6 (undercoating rubber roll 5 and intermediate coating rubber roll 6) that rotate in the forward direction.

The rubber rolls 5 and 6 have a structure in which rubber such as EPDM is coated on an appropriate roll core, as described above, so that the undercoat paint 18 and the intermediate coat paint 19 are applied to the bottom surface side of the concave portion 14. Further, it may be configured appropriately. For example, the rubber constituting the rubber rolls 5 and 6 may be softer than the rubber constituting the rubber rolls 4e and 4f used in the above-described removal step. The rubber hardness (hardness measured using a type A durometer according to JIS K 6253) may be, for example, about 50 to 60 degrees.
The undercoating paint 18 and the intermediate coating 19 need only have a lower gloss than the light-colored and high-gloss paint 21 described later, and may be matte (matte) or so-called 3 minute gloss or 5 minute gloss. Good.
The undercoat paint 18 and the intermediate paint 19 may be the same paint. For example, the undercoat paint 18 has good adhesion to the application surface, and the intermediate paint 19 has good wear resistance. May be. The undercoat paint 18 and the intermediate coat paint 19 may have different gloss levels.
Further, after applying the undercoat paint 18 and the intermediate coat paint 19 to each of them, a step of curing them may be executed.

  In addition, in this embodiment, as a process of forming the dark color and low gloss concave bottom surface side coating layer 20 on the bottom surface side of the concave portion 14, as a configuration including a dark color paint application process and a low gloss paint application process. However, these may be executed in the same process. That is, the removal step may be executed after applying a dark and low gloss paint on the surface including the bottom surface side of the concave portion 14. In other words, as shown in the figure, instead of a mode in which a coating layer in which the low gloss paints 18 and 19 are cured is formed on the surface side of the convex portion 16, a dark color applied to the surface side of the convex portion 16. In addition, the low gloss paint may be removed.

Next, as shown in FIGS. 3A and 3B, a light-colored light paint that is lighter than the dark-colored paint 17 and a high-gloss paint that is higher in gloss than the low-gloss paint (light-colored / high-gloss paint 21) A light color / high gloss paint application process is performed to apply to the front surface side of the convex portion 16 so as not to be applied to the bottom surface side. Thus, when the light-colored and high-gloss paint 21 is cured, a convex surface side coating layer 22 as a light-colored and high-gloss coating layer is formed on the surface side of the convex portion 16.
In this embodiment, as shown to Fig.3 (a), it is set as the structure which apply | coats the light color and the high gloss paint 21 by the roll coater method. In the present embodiment, a light-colored and high-gloss light-colored / high-gloss paint 21 is applied as the top coat 21 for finish coating. That is, the light color paint application process and the high gloss paint application process are executed as the top coat process in the same process. This overcoating process may be performed using a rubber roll 7 that rotates in the forward direction.

Similarly to the above, the rubber roll 7 has a configuration in which rubber such as EPDM is coated on an appropriate roll core, and has an appropriate configuration so that the light-colored and high-gloss paint 21 is not applied to the bottom side of the concave portion 14. It is good also as what was done. For example, the rubber constituting the rubber roll 7 may be harder than the rubber constituting the rubber rolls 5 and 6 to which the undercoat paint 18 and the intermediate coat paint 19 are applied. The rubber hardness (hardness measured using a type A durometer according to JIS K 6253) may be, for example, about 60 to 80 degrees.
The light-colored / high-gloss paint 21 may be a paint containing a colorant such as a pigment or a dye, and may be lighter than the dark-colored paint 17. For example, the light color / high gloss paint 21 It may be a lighter color paint than the material part 13 or a white paint. Further, the light-colored and high-gloss paint 21 may have a glossiness higher than that of the undercoat paint 18 and the intermediate coat paint 19 and may be glossy, and may have a so-called 7-minute gloss or a 5-minute gloss.
Further, the light-colored and high-gloss paint 21 may be adjusted to an appropriate viscosity so that it does not easily drip on the bottom surface side of the concave portion 14.
Further, after applying the light color / high gloss paint 21, a curing step may be executed.

In the present embodiment, an example in which the light color paint application process and the high gloss paint application process are executed in the same process is shown, but these may be executed in different processes. For example, any of the above-described undercoat paint 18 and intermediate coat paint 19 may be a paint containing a light color paint and applied to the surface side of the convex portion 16 so as not to be applied to the bottom surface side of the concave portion 14. Further, in place of such a mode of applying a light color paint during the finish coating, the light color paint is applied to the surface side of the convex portion 16 so as not to be applied to the bottom surface side of the concave portion 14 before the finish coating. It is good also as an aspect.
Further, in the illustrated example, the paint layers 17, 18, 19, and 21 are illustrated as if the coating layers 20 and 22 were formed in layers without penetrating into the wood board 10, but some of the coating layers seem to penetrate. It may be good.

The wood decorative board 1 according to the present embodiment can effectively enhance the three-dimensional effect of the surface on which the float-finishing process has been performed by adopting the above-described configuration.
That is, the concave bottom surface side coating layer 20 having a dark color and low gloss is formed on the bottom surface side of the concave portion 14 of the wood board 10, and the concave bottom surface side formed on the bottom surface side of the concave portion 14 on the surface side of the convex portion 16. The convex surface side coating layer 22 that is lighter and more glossy than the coating layer 20 is formed. Accordingly, it is possible to make the bottom surface side of the concave portion 14 where the concave bottom surface side coating layer 20 having a dark color and low gloss is formed deeply due to the difference in lightness and gloss from the surface side of the convex portion 16. It is possible to emphasize the uneven shape of the surface that has been subjected to the floating process. Thus, for example, as in the present embodiment, even when the wooden decorative board 1 is configured by laminating the single board 12 on the base material 11, the stereoscopic effect on the surface side is emphasized while the single board 12 is thin. can do. That is, it is possible to reduce the necessity of thickening the single plate so that the base material is not exposed when the floating process is performed so that the unevenness difference is increased. In addition, it replaces with such an aspect, and the whole wooden board | plate material 10 is good also as what consists of natural wood (solid material).

Moreover, the manufacturing method of the wooden decorative board 1 which concerns on this embodiment can manufacture the wooden decorative board 1 which concerns on this embodiment effectively by having set it as the above structures.
That is, the dark color paint 17 applied to the surface side of the convex portion 16 so that the dark color paint 17 applied to the surface including the bottom surface side of the concave portion 14 of the wood board 10 remains on the bottom surface side of the concave portion 14. And a step of applying the low-gloss paints 18 and 19 to at least the bottom surface side of the concave portion 14. Further, the light-colored paint that is lighter than the dark-colored paint 17 and the high-gloss paint that is higher in gloss than the low-gloss paints 18 and 19 (light-colored and high-gloss paint 21) The process of apply | coating to the surface side of 16 is provided. Therefore, a dark and low gloss concave bottom surface coating layer 20 is formed on the bottom surface side of the concave portion 14 on the surface of the wood board 10, and a light and high gloss convex surface surface coating film is formed on the surface side of the convex portion 16. The wooden decorative board 1 in which the layer 22 is formed and the three-dimensional effect is emphasized can be effectively manufactured. That is, for example, the wooden decorative board 1 with enhanced surface three-dimensional effect can be effectively manufactured as compared with a case where the unevenness difference is increased by increasing the number of times of floating processing. Further, the dark paint 17 applied to the surface side of the convex portion 16 including the bottom surface side of the concave portion 14 is removed so as to remain on the bottom surface side of the concave portion 14. Therefore, for example, compared with a configuration in which the dark color paint 17 is applied only to the bottom surface side of the concave portion 14 by inkjet coating or the like based on image data obtained by imaging the surface irregularity, the concave portion A dark coating layer 20 can be formed on the bottom surface side of 14.

Moreover, in this embodiment, it is set as the structure including the process using the sponge roll 4c in the removal process. Therefore, the dark color paint 17 can be absorbed and removed by the sponge roll 4c. In addition, for example, the sponge roll 4c has a convex portion 16 even when the wood board 10 is warped, as compared with a case where the dark paint 17 is scraped and removed using only a general metal reverse roll. It is possible to remove the dark color paint 17 on the surface side of the convex portion 16 effectively. In addition, it is good also as an aspect which does not include the process using sponge roll 4c in a removal process instead of such an aspect. For example, the removal step may be performed using a plurality of or single reverse rolls 4a, 4b, 4d as described above, or a plurality of or single rubber rolls 4e, 4f in addition to or instead of the reverse rolls 4a, 4b, 4d. Good.
Further, the application mode of the paints 17, 18, 19, and 21 and the removal mode of the dark paint 17 are not limited to the above examples, and various modifications are possible.
