Description

  The present invention relates to a decorative board used as a floor board or the like, and more particularly to a decorative board in which a plurality of pseudo grooves extending vertically and horizontally are cut on the surface in order to make it appear as if a plurality of pieces are joined.

  For example, as a decorative board such as a floor board, as shown in FIGS. 6A, 6B and 7, a surface decorative material 52 such as a veneer is attached to the surface of a base material 51 made of a 5-ply plywood or the like. In general, such a decorative plate 50 has a V-shaped cross section or a substantially V-shaped cross section extending in parallel from one end to the other end in the longitudinal direction so that a plurality of pieces appear to be joined together. Between the adjacent pseudo long grooves 50a and the adjacent pseudo long grooves 50a, a plurality of pseudo short grooves 50b having a V-shaped or substantially V-shaped cross section extending from one pseudo long groove 50a to the other pseudo long groove 50a are surfaces. Have been cut.

Japanese Patent Laid-Open No. 5-116105

  By the way, the pseudo long groove 50a and the pseudo short groove 50b cut on the surface of the decorative plate 50 as described above have a depth that reaches the base material 51 through the surface decorative material 52 such as a protruding plate. Therefore, the base material 51 is directly exposed on the inner surfaces of the cut pseudo long grooves 50a and pseudo short grooves 50b. However, the base material 51 has a lower quality than the surface decorative material 52 such as a veneer. Since the wood material is used, there is a problem in that the formation of the pseudo long groove 50a and the pseudo short groove 50b is likely to be crushed.

  Further, the plywood forming the base 51 may have a partially different color tone of each single plate constituting the base 51, and the pseudo long groove 50a extending from one end to the other end of the decorative plate 50 in the longitudinal direction. There is a problem that the color change of a single plate is more conspicuous than the pseudo short groove 50b having only the length between adjacent pseudo long grooves 50a. In particular, when a plurality of decorative plates 50 are used in combination, the pseudo long grooves 50a of the adjacent decorative plates 50 are connected to each other. Therefore, there is a partial color difference in one decorative plate 50. Even if it does not occur, the color tone of the pseudo long groove 50a portion may greatly differ between the decorative plates 50, and the pseudo long groove 50a portion compared to the pseudo short groove 50b that does not connect between the adjacent decorative plates 50. There is also a problem that the color tone is likely to change.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a decorative board in which the pseudo long groove portion formed on the surface is less likely to be rolled up or different in color.

  In order to solve the above-described problems, the invention according to claim 1 is directed from the one end to the other end in the longitudinal direction so that a surface decorative material is adhered to the surface of the base material and a plurality of pieces are joined. A decorative plate in which a plurality of pseudo long grooves extending and a plurality of pseudo short grooves extending in a short direction from one pseudo long groove to the other pseudo long groove are cut between the adjacent pseudo long grooves on the surface was cut. The surface of the base material to which the surface decorative material is attached is colored in a predetermined color so as to correspond to the formation position of the pseudo long groove so that the base material is not exposed on the inner surface of the pseudo long groove. The present invention provides a decorative board characterized in that a long groove for coloring filled with the resin composition is formed.

  The invention according to claim 2 is the decorative board of the invention according to claim 1, wherein the surface decorative material is adhered so that the base material is not exposed on the inner surface of the cut pseudo short groove. On the surface of the base material, colored short grooves filled with the resin compound colored in a predetermined color were formed so as to correspond to the formation positions of the pseudo short grooves.

  Further, the invention according to claim 3 is the decorative board of the invention according to claim 1 or 2, wherein the surface of the base material to which the surface decorative material is stuck is filled with a resin compound. A groove was formed.

  As described above, in the decorative board according to the first aspect of the present invention, the resin mixture colored in a predetermined color is filled in the long groove for coloring on the inner surface of the cut pseudo long groove instead of the base material. Since the objects will be exposed, even if a low-quality plywood is used as the base material, it is difficult for the pseudo long groove part to be rolled up, and the color difference in the pseudo long groove part where the color tone of the base material is conspicuous is effective. Can be prevented.

  In the decorative board according to the second aspect, not only the pseudo long groove but also the inner surface of the pseudo short groove exposes the resin compound colored in a predetermined color, not the base material. , It is possible to obtain an effect that it is difficult to generate a whisper or a color difference.

  In the decorative board of the invention according to claim 3, since a number of reinforcing grooves filled with the resin compound are formed on the surface of the base material to which the surface decorative material is stuck, the reinforcing grooves When the filled resin compound is cured, the surface hardness of the substrate increases, and even if an inexpensive ordinary plywood that does not have sufficient surface hardness is used as the substrate, sufficient surface hardness can be ensured. it can.

  Hereinafter, embodiments will be described with reference to the drawings. As shown in FIG.1 and FIG.2, this floor board 1 is the base material 10 which consists of a 5-ply plywood formed by laminating | stacking the five single plates 11-15, and the thickness stuck on the surface of this base material 10 It is composed of a surface decorative material 20 made of a 0.3 mm thick veneer, and the surface of the surface decorative material 20 adhered to the base material 10 in order to make it appear that a plurality of pieces are joined, Three pseudo long grooves 1A extending in the longitudinal direction are cut at regular intervals, and a plurality of pseudo short grooves 1B extending in the short direction between adjacent pseudo long grooves 1A are cut at random positions. . Since the pseudo long groove 1A and the pseudo short groove 1B are formed in a V-shaped cross section having a width of 2.0 mm and a depth of 0.7 mm, the pseudo long groove 1A and the pseudo short groove 1B penetrate the surface decorative material 20. As a result, the base material 10 is reached.

  Of the five single plates 11 to 15 constituting the base material 10, the single plate 11 constituting the uppermost layer is formed by a melee having a thickness of 1.0 mm and a specific gravity of 0.40, As shown in FIGS. 1, 2 and 4A, a resin compound (acrylic resin emulsion) colored in a standard material color so as to correspond to the formation positions of the pseudo long groove 1A and the pseudo short groove 1B. Colored long grooves 11A and colored short grooves 11B filled with 30 and having a width of 3.5 mm and a depth of 0.9 mm are formed.

  Therefore, on the inner surfaces of the cut pseudo long groove 1A and pseudo short groove 1B, as shown in FIGS. 2 and 3, the coloring long grooves 11A and the coloring short grooves are not the substrate 10 (single plate 11). The resin composition (acrylic resin emulsion) 30 filled in the average material color and filled in 11B is exposed.

  In addition, a large number of reinforcing grooves 11C having a width of 1.0 mm and a depth of 0.9 mm extending in the longitudinal direction are formed on the surface of the single plate 11 at a pitch of 3.0 mm. Similarly to the coloring long groove 11A and the coloring short groove 11B, a resin compound (acrylic resin emulsion) 30 colored in an average material color is filled.

The floor board 1 configured as described above is manufactured as follows. First, as shown in FIGS. 4 (a) and 5 (a), the surface (upper surface) of a base material 10 on which a single plate 11 made of melapie having a thickness of 1.0 mm and a specific gravity of 0.40 is laminated as an uppermost layer. ) Are formed on the surface of the veneer 11 to form the coloring long grooves 11A, the coloring short grooves 11B, and the reinforcing grooves 11C, as shown in FIGS. 4B and 5B. The acrylic long emulsion for coloring 11A, the short groove for coloring 11B, and the reinforcing groove 11C are filled with the acrylic resin emulsion by flowing an acrylic resin emulsion colored in a standard material color and having a solid content of 65%. The acrylic resin emulsion filled in the coloring long grooves 11A, the coloring short grooves 11B, and the reinforcing grooves 11C is immediately scraped uniformly with a reverse roll and left in a 50 ° C. atmosphere for 5 hours. It was 燥. The total amount of the acrylic resin emulsion applied to the surface of the substrate 10 on which the coloring long grooves 11A, the coloring short grooves 11B, and the reinforcing grooves 11C were formed was 350 g / m ² .

  In addition, the substrate 10 in which the long groove for coloring 11A, the short groove for coloring 11B, and the groove for reinforcing 11C cut in the surface in this way are filled with an acrylic resin emulsion colored in a standard material color, When the DuPont-type impact deformation test defined in JIS K 5600-5-3: 1999 was performed, the average dent amount after the impact test was 0.4 mm. In addition, the average depression amount of the base material made of ordinary plywood not subjected to such surface treatment is 0.7 mm, and the impact resistance is improved as compared with the base material made of ordinary plywood. I understand.

  Subsequently, as shown in FIGS. 4 (c) and 5 (c), a surface decorative material 20 made of a 0.3 mm thick flange plate is adhered to the surface of the substrate 10, and then the surface decorative material 20 is bonded. The pseudo long groove 1A and the pseudo short groove 1B having a V-shaped cross section having a width of 2.0 mm and a depth of 0.7 mm are formed on the surface, and finally, coloring and painting are performed, as shown in FIGS. A simple floor board 1 is completed.

  As described above, in the floor board 1, the cut pseudo long grooves 1A and the pseudo short grooves 1B are not filled with the coloring long grooves 11A or the coloring short grooves 11B on the inner surfaces of the acrylic long acrylic 11B. Since the resin emulsion is exposed, even if a low-quality plywood is used as the base material 10, an effect is obtained that it is difficult for the cut pseudo long groove 1A portion and the pseudo short groove 1B portion to be raised. .

  Further, since the acrylic resin emulsion filled in the coloring long groove 11A and the coloring short groove 11B is colored in a standard material color, the color of the bottom inner surface in the pseudo long groove 1A and the pseudo short groove 1B is standard. It is unified to a different material color. Therefore, even when the color tone of the base material 10 (single plate 11) is partially different or when the color of the base material is different between the adjacent floor plates 1 and 1 when laid, the color change is simulated. It does not appear in the long groove 1A portion and the pseudo short groove 1B portion, and it is possible to effectively prevent the color difference in the pseudo long groove 1A portion and the pseudo short groove 1B portion.

  Moreover, in this floor board 1, since many reinforcing grooves 11C filled with the acrylic resin emulsion are formed on the surface of the base material 10 to which the surface decorative material 20 is stuck, the reinforcing grooves 11C are filled. When the acrylic resin emulsion is cured, the surface hardness of the base material 10 is increased, and even if an inexpensive ordinary plywood that does not have sufficient surface hardness is used as the base material, sufficient surface hardness is ensured. Can do.

  In the above-described embodiment, the coloring long groove 11A, the coloring short groove 11B, and the reinforcing groove 11C are formed by cutting the surface of the substrate 10, but the present invention is not limited to this. For example, the coloring long groove 11A, the coloring short groove 11B, and the reinforcing groove 11C can also be formed by hot-pressing an embossed plate in which protrusions are formed at the groove forming position on the surface of the substrate 10.

  In the above-described embodiment, the coloring long groove 11A and the coloring short groove 11B are formed so as to correspond to both the pseudo long groove 1A and the pseudo short groove 1B. However, the present invention is not limited to this. The coloring long groove 11A may be formed so as to correspond to at least the pseudo long groove 1A in which the color tone of the substrate is easily noticeable, and the coloring short groove 11B and the reinforcing groove 11C are not necessarily formed.

  In the above-described embodiment, the base material 10 is formed by a 5-ply plywood, and the surface decorative material 20 is formed by a saddle bump. However, the present invention is not limited to this, and the base material and the surface decorative material may be various. Woody material can be used.

  Further, in the above-described embodiment, the acrylic resin emulsion is used as the resin compound to be filled in the coloring long groove 11A, the coloring short groove 11B, and the reinforcing groove 11C, but is not limited thereto. Various resin blends having toughness such as solvent-free two-component urethane resin, urea melamine, and epoxy-modified acrylic emulsion blend can be used. However, when it is not necessary to increase the surface hardness of the substrate 10 as in the case where the reinforcing groove 11C is not formed, the resin compound filled in the coloring long grooves 11A and the coloring short grooves 11B has toughness. You don't have to.

  Further, as described above, the resin composition can be sprayed as well as distributed on the surface of the substrate.

  Moreover, in each embodiment mentioned above, although the floor board was demonstrated, it is not limited to this, It cannot be overemphasized that it can apply to a various decorative board.
