Description

  The present invention relates to a woody decorative material in which a surface pattern of wood such as a grain pattern is printed on the surface of wood.

  Conventionally, in order to improve the design of the surface of wood, a wood-based decorative material having a resin sheet printed with a wood grain pattern on its surface has been used. However, not only the same grain pattern is repeatedly printed on the surface of the resin sheet, but the original wood texture cannot be obtained on the surface of the wood-based decorative material.

  In view of such points, for example, Patent Document 1 discloses that a printed layer having a wood grain pattern having a design such as a full-tone appearance is formed on the entire surface of wood, and the printed layer is in the visible light region. A wood-based decorative material made of an ultraviolet curable ink having a transmittance of 70% or more has been proposed. Patent Document 2 proposes a wood-based decorative material in which a wood grain pattern is printed on the surface of wood using fast-growing trees so that the surface of the wood can be seen using ultraviolet curable ink.

JP 2012-111069 A JP 2006-347149 A

  However, in the wood-based decorative material shown in Patent Document 1, a print pattern having a wood grain pattern is formed on the entire surface of the wood with an ink that transmits visible light. The formed irregularities are covered with the resin of the printing layer, and the surface of the wooden decorative material becomes a substantially flat surface. As a result, when the surface of the wooden decorative material is viewed from an oblique direction, for example, it appears that uniform stickiness occurs on the surface of the wooden decorative material, and the original wood texture of wood cannot be obtained.

  On the other hand, in the wood-based decorative material shown in Patent Document 2, a wood grain pattern is printed so as to expose the surface of the wood that is the base of printing, but the ultraviolet curable ink that is the printing ink is the wood that is the base. It adheres so that the recessed part formed according to the natural grain pattern of the surface of this may be filled up substantially. For this reason, the unevenness | corrugation formed according to the natural wood grain pattern is not formed in the surface of the wooden type decorative material after printing. Cannot get wood texture.

  The present invention has been made in view of such points, and the object of the present invention is to obtain the original wood texture of wood even when a wood surface pattern such as a wood grain pattern is printed on the surface of the wood. It is to provide a wood-based decorative material that can be used.

  As a result of intensive studies, the inventors have formed a fine shadow on the surface of the wood due to the unevenness of the surface of the wood formed according to the natural grain derived from the wood. We focused on affecting the original wood texture of wood.

  The wooden decorative material according to the present invention is a wooden decorative material in which a pattern is printed on the surface of wood, and a natural grain pattern derived from the wood is formed on the surface of the wood. The surface of the wood has a surface pattern of wood different from the natural wood grain pattern so that the natural wood grain pattern can be visually recognized while leaving the irregular shape of the surface of the wood formed according to the natural wood grain pattern. , Printed.

  According to the wood-based decorative material of the present invention, the surface pattern of the printed wood can be seen on the surface of the wood-based decorative material together with the natural wood grain pattern derived from the wood, so that the surface pattern is formed on the surface of the wood. Looks like it has been. In particular, since the surface of the wood-based decorative material on which the surface pattern of wood is printed has an uneven shape on the surface of the wood formed according to the natural wood grain pattern, The original wood texture of wood can be obtained.

  Here, “the uneven shape of the surface of the wood formed according to the natural wood grain pattern” as used in the present invention means the uneven shape formed by the wood fibers constituting the wood, and the wood conduit or temporary conduit The concavo-convex shape originated from “to leave this concavo-convex shape” means that the concave portion of the concavo-convex shape is not completely filled with printing ink.

  Further, in the present invention, “the natural wood grain pattern can be visually recognized” means that the natural wood grain pattern on the surface of the wood, which is the base for printing, is entirely observed when the surface of the wood-based decorative material is viewed. It means that it can be confirmed.

  Here, the wood-based decorative material may be printed with the above-described surface pattern of wood on the surface of uncolored wood (wood substrate). The surface of the wood is colored, and the surface pattern is printed on the surface of the colored wood.

  According to this aspect, the wood-based decorative material has the above-described wood surface pattern printed on the surface of the colored wood. Therefore, when printing the wood surface pattern, the color desired to color the entire surface of the wood. There is no need to print on. Thereby, it is possible to print the wood-based decorative material quickly and inexpensively. In particular, since the surface pattern of the wood is printed on the surface of the wood colored with the base, the boundary between the colored surface that is the base and the surface pattern of the printed wood on the surface of the wood-based decorative material. Suppresses bleeding and makes the wood surface pattern stand out.

  More preferably, the surface pattern is knots, cracks, wrinkles, perforated skin, gold bars, sugar bars, false cores, vertices, uneven colors, patterns of edges, patterns of nail holes, or saw-tooth patterns. Among the patterns according to the scar, at least one pattern is included.

  Here, among the surface patterns described above, knots, cracks (of natural wood), wrinkles, perforated skin, gold bars, sugar bars, false cores, ate, uneven color, and edge patterns are made of wood. It is a unique pattern, and a crack pattern (at the time of processing), a pattern of a nail hole mark, or a pattern according to a saw mark is a processed pattern formed when processing wood. In addition, the pattern according to the saw scar is the pattern of the saw scar (Raw Thorn) and when the paint is applied to the surface of the wood where the saw scar is formed, the surface other than the saw scar is colored. A pattern.

  Here, when these patterns are formed on actual wood instead of printing, it is generally determined that the pattern is not good. This is because if one piece of wood having these patterns is mixed with a plurality of pieces of good wood, the wood becomes conspicuous.

  However, according to this aspect, since a plurality of wood-based decorative materials on which these surface patterns are printed can be used on the floor surface or the wall surface, unique design with a natural feeling can be obtained indoors. Furthermore, when a pattern corresponding to these patterns is formed on actual wood instead of printing, the woody decorative material according to this aspect can be used in combination with this wood (non-defective wood). As a result, it is possible to use wood as a decorative material without discarding wood that is originally considered to be non-defective.

  In particular, wood with these patterns that are considered to be non-defective products cannot be produced intentionally, so the amount is small and it is difficult to collect them. However, it is possible to stably supply the wood on which these patterns are formed by supplementing the lack of the woody decorative material printed with such patterns.

  Here, as a preferable aspect in the case where a seam in which a plurality of pieces of wood are joined together is formed on the surface of the wood, the wood-based decorative material is placed on the surface of the adjacent pieces of wood through the joint. The surface pattern is printed continuously. According to this aspect, since the surface pattern of the wood is continuously printed on the surfaces of the adjacent wood pieces via the joints between the wood pieces, the plurality of wood pieces can be seen as one piece of wood.

  Further, a chamfered portion is formed at the periphery of the surface of the wood, and the surface pattern is continuously printed on the surface of the chamfered portion from the surface of the wood. According to this aspect, since the surface pattern is continuously printed on the surface of the chamfered portion from the surface of the wood, it looks like a thick woody decorative material.

  Furthermore, as a preferable aspect in the case where a concave groove or a concave portion is formed on the surface of the wood, the surface pattern is also printed on the wall surface forming the concave groove or the concave portion. According to this aspect, since the surface pattern of the wood is printed on the wall surface forming the concave groove or the concave portion, it looks as if the concave groove or the concave portion is formed on one piece of wood.

  According to the present invention, even when a wood surface pattern such as a wood grain pattern is printed on the surface of the wood, the original wood texture of the wood can be obtained.

It is the typical perspective view which showed the wooden floor material (wood) which concerns on this embodiment, and the surface pattern of the timber printed.

  The present embodiment will be described below with reference to the drawings.

1. About the wooden flooring 2 on which the surface pattern 3 is printed The wooden decorative material 1 according to the present embodiment has a wood surface pattern 3 to be described later on the surface 2a of the wooden flooring 2 as shown in FIG. The wooden flooring 2 corresponds to the “wood” in the present invention. In the present embodiment, the wood-based flooring 2 is illustrated as the wood to be printed. However, if a natural wood grain pattern is formed on the surface, a wall material, a step board, a ceiling material, etc. There is no particular limitation.

  In this embodiment, as shown in FIG. 1 and FIG. 2, the wooden flooring 2 has a plurality of (specifically four) protruding plates (wood pieces) on the surface 21 a of the wooden base material 21 made of 7-ply plywood. ) 23 is affixed, and a seam 24 is formed between the adjacent projecting plates 23, 23.

  A chamfered portion 25 is formed at the periphery of the surface 2 a of the wooden floor material 2, and the chamfered portion 25 is formed from the surface 23 a of the protruding plate 23 to a part (side surface) of the wooden base material 21. . A male real part 22a and a female real part 22b are formed on the periphery of the side surface of the woody base material 21. By engaging the male solid part 22a of the wooden flooring 2 and the female solid part 22b of the wooden flooring 2 adjacent thereto, the wooden flooring 2 and 2 (wooden decorative materials 1 and 1) are connected to each other. Real joining is possible.

  Here, in this embodiment, the plywood is taken as an example of the wood-based base material 21, but for example, particle board (PB), wood fiber board (MDF, insulation board, hard board, etc.), oriented strand board ( OSB), LVL, laminated wood, solid wood, and the like, and the above-described protruding plate 23 can be attached to the surface 21a, and the rigidity and strength of the wooden flooring 2 (woody decorative material 1) The material and thickness are not particularly limited as long as it can be secured.

  The veneer 23 is a veneer in which a natural wood grain pattern derived from the veneer 23 (wood) is formed on the surface 23a, and is a veneer used as a surface decorative material for making up the surface of the woody base material 21. . As the material of the veneer, for example, beach, oak, maple, zelkova, walnut, china, oak, yachidamo, drill, cypress, cedar, mahogany, teak, rosewood, tochi, blackwood, shioji, elm, hippopotamus, rosewood, or You can list octane. The thickness of the protruding plate 23 is preferably in the range of 0.1 to 1.0 mm.

  Here, in this embodiment, the veneer 23 was used as a surface decorative material having a natural wood grain pattern derived from wood formed on the surface thereof. However, for example, instead of the veneer plate 23, a ground plate made of the above-described material (with a natural wood grain pattern formed on the surface) may be used as a surface decorative material for making up the surface of the woody base material 21. In that case, the thickness of the grinding board is preferably in the range of 1 mm to 3 mm.

  In sticking the projecting plate 23 to the wooden base material 21, a wooden base material is obtained by applying an adhesive to at least one of the front surface 21a of the wooden base material 21 or the rear surface of the projecting board 23 and curing the adhesive. A protruding plate 23 is bonded to the surface of 21. The above-described male real part 22a, female real part 22b, and chamfered part 25 are processed after they are bonded.

  Furthermore, the surface of the veneer 23 may be colored with a colorant using a roll coater or the like before or after the veneer 23 is adhered to the woody substrate 21. By performing such coloring, the wood texture of the veneer 23 can be emphasized, and the surface pattern 3 of wood described later can also be emphasized. Examples of the colorant include a dye colorant, a pigment colorant, and a chemical colorant.

  Here, on the premise that the natural grain pattern of the veneer 23 and the unevenness of the surface of the wood formed accordingly remain, the colorant is impregnated from the surface 23a of the veneer 23 to the surface layer, and the surface 23a is colored. The colorant type and the coloring method are not particularly limited as long as they can be made (at least different from the color of the material).

  Note that a plurality of soundproofing grooves may be formed on the back surface of the wooden flooring 2, and an impact cushioning material such as a foamed rubber sheet or a foamed resin sheet may be adhered to the paper, non-woven fabric. Further, a lining material of cloth (felt etc.) may be attached.

2. About the wooden decorative material 1 As shown in FIG. 1 and FIG. 3, the surface pattern (printing pattern) 3 of wood is printed on the surface 2a etc. of the wooden floor material 2 mentioned above, and the wooden decorative material 1 is obtained. Can do. Specifically, on the surface 23a of the protruding plate 23, a natural grain pattern of the surface 23a of the protruding plate 23 is formed, and the uneven shape of the surface 23a of the protruding plate 23 formed according to the natural grain pattern is left. On the other hand, a wood surface pattern 3 different from the natural wood grain pattern on the surface 23a of the protruding plate 23 is printed so that the natural wood grain pattern can be visually recognized.

  In the present embodiment, the surface pattern 3 is a pattern in which a knot pattern 31 is formed on a wood grain pattern 32. The wood surface pattern 3 is, for example, an actual wood surface pattern in which nodes that are not normally used are formed. Such a pattern can be obtained by taking an image of the actual wood surface on which the nodes are formed as an image and printing a pattern (a wood surface pattern) according to the taken image.

  The printing of the wood surface pattern 3 is performed using an ink jet printer (not shown). In the present embodiment, the ink of the ink jet printer is composed of, for example, four colors of yellow, magenta, cyan, and black. Using these inks, as shown in FIG. To print.

  The ink jet printer contains ink used for general printing, a head that individually ejects each ink in accordance with the surface pattern 3 to be printed based on the above-described image, and a feeder that feeds the wooden flooring 2 , At least.

  Using such an ink jet printer, each ink is ejected by the head from a direction substantially orthogonal to the surface 2a of the wooden flooring 2 according to the surface pattern 3, and the wooden flooring 2 is fed by the feeder. The surface pattern 3 is printed on the surface 2a of the wooden flooring 2 (specifically, the surface 23a of the protruding plate 23), the upper surface 22c of the male part 22a, and the surface 25a of the chamfered part 25 (FIGS. 3 and 6). (See (a)).

  Specifically, by printing the surface pattern 3 on the wooden flooring 2, the surface 23 a of the projecting plate 23, the surface 25 a of the chamfered portion 25, and the surface 1 a of the wooden decorative material 1 are viewed in plan view. The surface pattern 3 printed on the upper surface 22c of the male part 22a is printed so that it looks like one continuous grain pattern.

  Here, when an ultraviolet curable ink is used as the printing ink for the surface pattern 3, the ultraviolet curable ink is applied to the surface of the wooden floor material 2 so as to become the surface pattern 3 by the ink jet printer described above. After application, the surface is irradiated with ultraviolet rays to cure the ink. Examples of the ultraviolet curable ink include an ink composed of a generally known reactive oligomer, reactive monomer and photopolymerization initiator, an ultraviolet curable resin, and a colorant.

  As shown in FIG. 4 (a), the surface 2a (23a) of the wooden flooring 2 (projection plate 23) has an uneven shape corresponding to the natural wood grain pattern of the projection plate 23, and the surface pattern 3 is printed. In this case, the dot-like or island-like ink 34 adheres to the surface 2a (23a) as shown in FIG. 4 (b).

  Here, in the present embodiment, unlike the techniques of Patent Documents 1 and 2 described above, ink having a fine particle size is sprayed onto the surface 2 a of the wooden flooring 2. Specifically, the ink droplets sprayed on the surface of the wooden flooring 2 are preferably in the range of 1 to 20 pl, and more preferably in the range of 3 to 14 pl.

  Thereby, after irradiating with ultraviolet rays, the average diameter of the ink adhered to the surface 2a (ink diameter as viewed from the direction orthogonal to the plane of the wooden flooring) is in the range of 15 to 150 μm (as the distribution, The average diameter is 40 to 60 μm, and the ink 34 is adhered to the surface 2a so that the surface 2a of the wooden flooring 2 is partially exposed while leaving the uneven shape of the surface 2a.

  In this manner, the surface 2a of the wooden flooring 2 2 (surface 23a of the protruding plate 23) is left with the uneven shape of the surface 23a of the protruding plate 23 formed according to the natural wood grain pattern (that is, the concave portion of the surface 23a). The surface pattern 3 can be printed without completely filling the space 23b with the ink 34).

  Further, as shown in FIG. 5A, a knot pattern 31 is formed on the surface 23a of the veneer on which a natural wood grain pattern (the figure shows an oak wood grain pattern) is formed, on the wood grain pattern 32 shown in FIG. The surface pattern 3 to be included may be printed. As a result, on the surface of the obtained wood-based decorative material, as shown in FIG. 5 (c), the natural grain formed on the surface 23a of the veneer that is the base, together with the surface pattern 3 including the knot pattern 31 The pattern can be visually recognized.

  Thus, according to the wooden decorative material 1, the surface 1a of the wooden decorative material 1 includes a natural wood grain pattern derived from the veneer 23 and a surface including a wood node pattern 31 different from this wood grain pattern. Since the pattern (wood grain pattern) 3 can be seen, it appears as if the wood grain pattern is formed on the surface 1 a of the wooden decorative material 1.

  In particular, on the surface 1a of the woody decorative material 1 on which the surface pattern 3 is printed, the uneven shape of the surface 23a of the protruding plate 23 formed according to the natural wood grain pattern is formed (remains). The wood texture of the veneer 23 can be obtained on the surface 1 a of the wooden decorative material 1.

  Here, as shown in FIG. 4C, when the surface 23 a of the protruding plate 23 is colored as described above to form the colored layer 23 c, the ink 34 is applied to the colored surface 23 a of the protruding plate 23. And the surface pattern 3 may be printed. Since the surface pattern 3 described above is printed on the surface 23a of the colored protruding plate 23, when the surface pattern 3 is printed, it is not necessary to print the entire surface of the protruding plate 23 in a color to be colored. Thereby, the wooden type decorative material 1 can be printed quickly and inexpensively.

  In particular, since the surface pattern 3 is printed on the surface 23 a of the veneer 23 colored with the base, the surface 23 a of the color veneer 23 that is the base and the surface pattern 3 on the surface 1 a of the wooden decorative material 1. The surface pattern 3 can be made to stand out.

  In FIGS. 4B and 4C, since the ultraviolet curable ink is used as the printing ink, the ink 34 is hardly impregnated into the surface 23a of the protruding plate 23, and a clear surface pattern is obtained. Can do. However, water-based ink or oil-based ink may be used for printing ink.

  When such ink is used, the surface 34a of the protruding plate 23 is impregnated with the ink 34A as shown in FIG. As a result, the wooden decorative material 1 can clearly leave the uneven shape of the surface 23a of the veneer 23 formed according to the natural wood grain pattern of the surface 23a of the veneer 23, and the surface of the veneer 23 together with the surface pattern 3 The natural wood grain pattern formed on 23a can be visually recognized.

  Moreover, in this embodiment, as shown in FIG. 3 and FIG. 6A, a surface pattern is formed on the surfaces 23a, 23a of the adjacent projecting plates 23, 23 via the joint 24 where the projecting plates 23, 23 are joined together. Since 3 is printed continuously, the plurality of protruding plates 23 and 23 look like one protruding plate.

  Further, as shown in FIG. 6A, the chamfered portion 25 is formed from the surface 23a of the protruding plate 23 to a part of the wooden base material 21, and the surface pattern (wood grain) is also formed on the surface 25a of the chamfered portion 25. 3) is continuously printed from the surface 23a of the protruding plate 23. As a result, the boundary line 27 between the protruding plate 23 and the wooden base material 21 becomes inconspicuous, and the wooden decorative material 1 looks like a solid material.

  Furthermore, in this embodiment, as shown in FIG. 6A, the surface pattern 3 is also formed on the upper surface 22c of the male part 22a. As a result, as shown in FIG. 6 (b), in the state where the wooden decorative materials 1 and 1 are actually joined to the floor base surface F, the adjacent wooden decorative materials 1 and 1 contract with each other. Even if the gap S is formed, the surface pattern 3 on the upper surface 22c of the male part 22a can be seen from the gap S. Thereby, the clearance gap S formed between the wooden type decorative materials 1 and 1 can be made inconspicuous.

  As described above, in the wooden flooring 2 shown in FIG. 2, the four protruding plates 23 are attached to the surface 21 a of the wooden base 21. In the wooden decorative material 1 according to the modification shown in FIG. 7, after sticking one protruding plate 23 ′ on the surface of the wooden base material 21 on the wooden flooring 2 </ b> A before printing, by groove processing, A concave groove (V groove) 26 is formed on the surface 2 a of the wooden floor material 2. In this modification, the concave groove 26 penetrates the protruding plate 23 ′ and reaches the wooden base material 21, and the wooden flooring 2 has four divided protruding plates 23 </ b> A to 23 </ b> D divided by the concave groove 26. Is formed.

  A surface pattern 3A shown in FIG. 7 is printed on the surface of such a wooden flooring 2A. In this modification, the surface pattern 3A is composed of four different wood grain patterns (surface patterns) 32A to 32D, and adjacent wood grain patterns (for example, wood grain patterns 32A and 32B) have a gap (blank) across the boundary line 33. There is no pattern. In this modification, a knot pattern 31 is formed on the wood grain pattern 32B.

  Here, as shown in FIGS. 8A and 8B, the surface pattern 3 </ b> A is made of wood so that the boundary line 33 between the grain patterns is located on the wall surface 26 a of the groove 26 along the groove 26. It is printed on the surface 2a of the system flooring 2A, the wall surface 26a of the concave groove 26, and the like. More specifically, the surface pattern 3 </ b> A is printed such that the boundary line 33 between the wood grain patterns is located at the bottom 26 b of the groove 26 along the groove 26.

  By printing the surface pattern 3A in this way, the four wood grain patterns 32A to 32D are printed on the respective surfaces of the four divided protruding plates 23A to 23D corresponding thereto. Furthermore, the wood grain patterns 32A to 32D (surface pattern 3A) corresponding to this are continuously printed on the wall surface 26a of the concave groove 26 that is continuous with each of the divided protruding plates 23A to 23D. Furthermore, the wood grain patterns 32A to 32D are printed on the surface of the chamfered portion 25 and the upper surface of the male portion 22a as in the embodiment shown in FIG.

  In this way, as shown in FIG. 8B, the boundary lines 27 between the divided projecting plates 23A to 23D formed on the wall surface 26a of the concave groove 26 and the woody base material 21 become inconspicuous, and each grain pattern 32A to 32A The four parts printed with 32D appear to consist of four solid woods, each with a different wood grain pattern. Thereby, the wooden texture of the wooden decorative material 1 can be further enhanced.

  In this modification, a V-groove is used for the concave groove 26, but other groove shapes such as a U-groove and an R-groove may be used.

  When a plurality of wood-based decorative materials 1 as shown in FIGS. 3 and 8 are laid on the floor base surface, a unique design with a natural feeling can be obtained in the room. Furthermore, if these wooden decorative materials 1 are used together with wood having actual knots, the wood having actual knots can be suitably used without a sense of incongruity.

  In the present embodiment, the surface pattern of wood including nodes is printed as the surface patterns 3 and 3A. However, for example, cracks, wrinkles, perforated skin, metal bars, which are not considered to be good as the surface pattern of conventional wood, for example, In addition, patterns unique to wood, such as sugar stripes, false cores, ate, uneven color, and patterns of edges, may be included.

  Further, as shown in FIG. 9 (a), as shown in FIG. 9 (b), a pattern of a saw mark (rafthorn) formed when cutting wood is cut as a surface pattern 3B as shown in FIG. 9 (b). Good.

  Further, as shown in FIG. 10 (a), a saw-shaped scar pattern is formed on the surface 23a of the veneer on which a natural wood grain pattern (the figure is an oak wood grain pattern) is formed, as shown in FIG. 10 (b). The surface pattern 3C to be included may be printed. Thereby, on the surface 1a of the obtained woody decorative material 1, as shown in FIG. 10 (c), it looks as if a scar of a saw is formed on the veneer on which a natural wood grain pattern is formed. Note that FIG. 10B shows a saw mark pattern in an image in a range of 160 × 220 mm.

  Further, as shown in FIG. 11 (a), a surface pattern including a saw mark pattern and a crack pattern shown in FIG. 11 (b) on a veneer on which a natural wood grain pattern (the figure is an oak wood grain pattern) is formed. 3D may be printed. Thereby, on the surface 1a of the obtained woody decorative material 1, as shown in FIG. 11 (c), a saw mark and a crack are formed on the veneer on which a natural wood grain pattern is formed. appear. As described above, the surface patterns 3C and 3D may be printed on the top surfaces of the chamfered part and the male part as well.

  Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various designs can be made without departing from the spirit of the present invention described in the claims. It can be changed.
