  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
FIG. 1 shows a decorative material A according to Embodiment 1 of the present invention. The decorative material A is configured by laminating a printed layer 3, a transparent adhesive layer 5, a decorative veneer 7 and a surface coat layer 9 in this order on the base plate 1.

  As the base plate 1, a wood board such as plywood, MDF, LVL, particle board, a wood composite board in which thin MDF is laminated and bonded to the surface of these wood boards, or a resin on the surface of these wood boards or wood composite boards A wooden substrate having a surface or a resin-impregnated paper layer and having a reinforced surface can be suitably used. Other than such a wooden substrate, an inorganic board such as an inorganic fiber board or a volcanic glassy multilayer board, a synthetic resin board, or the like can also be used as the base plate 1.

  As shown in FIG. 1A, the decorative veneer 7 is made of a thin wood veneer having a predetermined wood grain pattern 11 and is subjected to a WPC (Wood Plastic Combination) treatment in which the wood veneer is impregnated with a resin. Therefore, transparency is imparted. On the decorative projecting plate 7, a wood grain pattern 11 is formed by a soft spring eye portion 11a and a hard autumn eye portion 11b, and the autumn eye portion 11b is darker than the spring eye portion 11a.

  The woody thin veneer forming the decorative veneer 7 is a thin single plate of natural wood, and the tree species is not limited. For example, hard tree species such as oak, birch, beach and cherry, and soft tree species such as cedar, tsuga, hinoki and sawawagurumi are used. The pattern 11 of the decorative veneer 7 is shown in a grid pattern for convenience of explanation (see FIG. 1A).

  Here, the resin impregnated in the wood thin veneer will be described in detail. As this resin, for example, two resins of an impregnation resin and a colored filling resin are used. Both the impregnating resin and the colored filling resin have both active energy ray curing characteristics and moisture curing characteristics. For this reason, compared with resin which has only an active energy ray hardening characteristic, resin can be hardened instantaneously by irradiation of an active energy ray.

  Both resins are mainly composed of oligomers or polymers such as polyester acrylates, epoxy acrylates, urethane acrylates, polyether acrylates, or the like obtained by adding a reactive monomer to a mixture of them. Furthermore, both resins are made by adding 1% by mass or more and 15% by mass or less of polyisocyanate with respect to the main component.

  The oligomer, polymer, and reactive monomer used for both resins may be those generally used as resins having active energy ray curing characteristics. The following are mentioned as an example of the reactive monomer used for both resin.

  Examples of monofunctional monomers include lauryl acrylate, 2-ethylhexyl acrylate, 2-hydroxyethyl acrylate, 1,6-hexanediol monoacrylate, dicyclopentadiene acrylate, 2-hydroxylpropyl acrylate, phenoxydiethylene glycol acrylate, isobornyl acrylate , Β-carboxyethyl acrylate, acryloyl morpholine, 2-hydroxyethyl acryloyl phosphate, tetrahydrofurfuryl acrylate, N, N-diethylaminoethyl acrylate, N, N-dimethylaminoethyl acrylate, glycidyl acrylate, benzyl acrylate and the like.

  Examples of bifunctional monomers include ethylene glycol dimethacrylate, diethylene glycol diacrylate, diethylene glycol dimethacrylate, triethylene glycol diacrylate, triethylene glycol dimethacrylate, polyethylene glycol diacrylate, polyethylene glycol dimethacrylate, dipropylene glycol diacrylate. Acrylate, dipropylene glycol dimethacrylate, tripropylene glycol diacrylate, tripropylene glycol dimethacrylate, polypropylene diacrylate, polypropylene dimethacrylate, 1,6-hexanediol diacrylate, 1,4-butanediol diacrylate, 1 , 4-Butanediol dimethacrylate, neopentylglyco Diacrylate, neopentyl glycol dimethacrylate, 1,9-nonanediol diacrylate, 1,9-nonanediol dimethacrylate and the like.

  Examples of trifunctional monomers include trimethylolpropane triacrylate, trimethylolpropane trimethacrylate, ethoxylated trimethylolpropane triacrylate, ethoxylated trimethylolpropane trimethacrylate, pentaerythritol triacrylate, pentaerythritol trimethacrylate, glycerin propoxy A triacrylate etc. are mentioned.

  Examples of the tetrafunctional or higher functional monomer include pentaerythritol tetraacrylate, ethoxylated pentaerythritol tetraacrylate, propoxylated pentaerythritol tetraacrylate, ditrimethylolpropane tetraacrylate, dipentaerythritol hexaacrylate, and the like.

  Moreover, it is preferable that an isocyanate type compound is added to both resin. This isocyanate compound absorbs moisture in the air and contributes to moisture curing of both resins. For this reason, the adhesiveness to the woody thin single board of both resin can be improved more.

  Specific examples of isocyanate compounds include isocyanate monomers such as hexamethylene diisocyanate, isophorone diisocyanate, tolylene diisocyanate, diphenylmethane diisocyanate, xylylene diisocyanate, norbornene diisocyanate, and biuret, isocyanurate, and trimethylolpropane adducts. And the like, and block bodies of these isocyanate monomers or polyisocyanate derivatives. Furthermore, it is preferable to use a non-yellowing type or a hardly yellowing type isocyanate compound. These isocyanate compounds are used alone or in combination.

  Further, a commonly used catalyst such as a tin compound, a zinc compound, or an amine compound may be added to both resins.

  Specifically, the above impregnating resin is applied to the entire surface of the thin wood veneer. The impregnating resin is applied using a sponge roll coater, a natural reverse coater, a flow coater or the like. Alternatively, the resin is impregnated with a pressure cooker under high pressure conditions.

  The impregnating resin is preferably a resin having a low viscosity and a high impregnation property. Specifically, the impregnating resin preferably has a viscosity of 100 Pa · s or less when applied to the surface of a thin wood veneer. Thus, the impregnation property can be further improved by making the impregnating resin have a low viscosity. The impregnating resin is adjusted so as to have the above-mentioned viscosity by being diluted with the above-described monomer or heated. Also, for example, the wood thin veneer is heated in advance so that the surface temperature of the wood thin veneer is 40 ° to 50 °, and the impregnating resin is applied at a temperature 10 ° to 20 ° lower than the surface temperature. By doing so, the impregnation property of the impregnating resin can be further improved. Furthermore, the above-mentioned resin may be impregnated into the thin wood veneer by a pressure-injection method under reduced pressure.

  In order to harden or semi-harden the impregnating resin, active energy rays are irradiated from the surface side of the thin wood veneer. Ultraviolet rays or electron beams are used for the active energy rays.

  When the active energy ray is ultraviolet light, a photopolymerization initiator is added to the impregnating resin. As the photopolymerization initiator, commonly used radical reaction type acetophenone-based, benzophenone-based, benzyl-based, benzoin-based carbonyl compounds, tetraalkylthiuram monosulfide, thioxanthone and other sulfur compounds are used alone or in combination. You may mix and use. However, in order to accelerate the curing of the impregnated resin, those having higher reactivity with respect to ultraviolet rays than the above general photopolymerization initiator are preferable.

  Specifically, as the photopolymerization initiator, the impregnating resin contains bisacylphosphine oxide in an amount of 0.1% by mass to 1.5% by mass, or monoacylphosphine oxide in an amount of 0.5% by mass to 5%. It is preferable to contain 0.0 mass% or less. Bisacylphosphine oxide or monoacylphosphine oxide has an absorption maximum at a long wavelength in which the wavelength region of ultraviolet rays is around 350 nm to 400 nm. Therefore, the impregnating resin 8 can be cured more effectively by using a light emission method having an emission spectrum in a long wavelength region of 350 nm or more and 400 nm or less as a light source that emits ultraviolet rays. Specifically, a discharge lamp type metal halide lamp, an electrodeless type D bulb, a V bulb, a Q bulb, an M bulb, a pulse UV method, or the like is used.

  Further, when the active energy ray is ultraviolet light, an auxiliary agent such as a sensitizer, a light stabilizer, an ultraviolet absorber, or a storage stabilizer may be added to the impregnating resin. Further, coloring may be performed by adding a dye, a pigment or the like to the impregnated resin.

  The printed layer 3 scans the pattern 11 of the decorative veneer 7 with a scanner, and a digital image 11B (see FIG. 4B) digitally processed by a personal computer device based on the scanned pattern 11A (see FIG. 4A). The printing layer 3 is formed on the base plate 1 by ink jet printing.

  The above digital processing includes tuning, darkening processing, lightening processing, intensity change (taste, redness, blueness), inversion processing, gradation processing, mosaic processing, glass processing, wave processing, coarse pixelation There are processing.

  The transparent adhesive layer 5 needs to contain not only a transparent adhesive in a cured state but also a translucent adhesive, and the color pattern of the printing layer 3 can be transmitted or translucent to the surface thereof. Specifically, such a transparent adhesive layer 5 is a cured product of an adhesive such as urea / melamine resin, melamine resin, ethylene vinyl acetate resin, vinyl urethane resin, or a small amount of a color pigment mixed in these adhesives. A translucent cured body of the colored adhesive can be used.

  The decorative veneer 7 is adhered to the printing layer 3 printed on the base plate 1 via the transparent adhesive layer 5. The digital image 11B of the printed layer 3 and the pattern 11 of the decorative veneer 7 may be completely overlapped, or both may be displaced by 0.1 mm to 2 mm, and each has a different pattern. Can be issued. The reason why the upper limit of the positional deviation is set to 2 mm is that, if it exceeds 2 mm, the harmony between the pattern 11 of the decorative veneer 7 and the digital image 11B is lost, and it is difficult to obtain a natural, deep and rich pattern. .

  As the surface coat layer 9, any resin can be used as long as it exhibits transparency after curing, for example, urethane acrylate resin, epoxy acrylate resin, methacrylate resin, etc. Those which are added and become translucent after curing can also be used.

  In the decorative material A configured as described above, the digital image 11B of the printing layer 3 can be viewed from the front side of the decorative veneer 7.

  According to this, the digital image 11B of the printing layer 3 is a digital image digitally processed based on the scanned pattern 11A of the decorative veneer 7 on the front side, and the digital image can be viewed from the front side of the decorative veneer 7. Therefore, the pattern 11 of the decorative veneer 7 and the digital image 11B are in harmony, and the decorative material A having a natural deep and full of pattern can be obtained.

  Next, the manufacturing method of the decorative material A according to Embodiment 1 will be described with reference to FIGS. The numbers given in parentheses below indicate the order of the manufacturing process.

  (1) The pattern 11 of the decorative veneer 7 is scanned with a scanner (scanning process: step S1 in FIG. 2). FIG. 4A shows a scanned pattern 11A.

  (2) The scanned pattern 11A of the decorative veneer 7 is digitally processed using a personal computer device to form a digital image 11B (digital image forming step: step S2 in FIG. 2). Here, the digital processing is illustrated as a yellow solid processing (see FIG. 4B).

  (3) The digital image 11B is inkjet-printed on the base plate 1 to form the print layer 3 as shown in FIG. 3A (print layer forming step: step S3 in FIG. 2).

  (4) A transparent adhesive is applied to the printing layer 3 (adhesive application step: step S4 in FIG. 2), and a transparent adhesive layer 5 is formed as shown in FIG. 3 (b).

  (5) As shown in FIG.3 (c), the said decorative veneer 7 is stuck to the said printing layer 3 via a transparent adhesive (transparent adhesive layer 5) (sticking process: step S5 of FIG. 2). . At this time, as shown in FIG. 4 (c), the digital image 11B of the printed layer 3 and the pattern 11 of the decorative veneer 7 may be completely overlapped, as shown in FIG. 4 (d). May be displaced by 0.1 mm to 2 mm.

  (6) As shown in FIG. 3 (d), the decorative projecting plate 7 is subjected to WPC treatment by resin impregnation so that the digital image 11B of the printed layer 3 can be viewed from the front side of the decorative projecting plate 7 (WPC processing step: Step S6 in FIG.

  (7) A transparent resin is applied to the decorative veneer 7 after the WPC treatment to form a surface coat layer 9 as shown in FIG. 3 (e) (surface coat layer forming step: step S7 in FIG. 2). Thereby, the decorative material A in which the base plate 1, the printing layer 3, the transparent adhesive layer 5, the decorative veneer 7 and the surface coat layer 9 are laminated and integrated is obtained.

(Embodiment 2)
FIG. 5 shows a decorative material A according to Embodiment 2 of the present invention. Since this decorative material A is configured in the same manner as in the first embodiment except that the decorative veneer 7 is floated by shot blasting, only the different points will be described. The same components are denoted by the same reference numerals and the description thereof is omitted.

  In other words, the decorative veneer 7 is formed by subjecting the surface of the thin wood veneer to a floating process so that the soft spring portion 11a of the veneer is recessed deeper than the hard autumn portion 11b, and the spring portion 11a becomes a recess. An uneven portion in which the Akume portion 11b is a convex portion is formed and subjected to WPC processing, and the Akume portion 11b (convex portion) has a darker color on the surface than the spring eye portion 11a (concave portion) ( (Kiri) pattern is formed.

  Specifically, the above impregnating resin is applied to the entire surface of the wood thin veneer that has been shot blasted. The impregnating resin is applied using a sponge roll coater, a natural reverse coater, a flow coater or the like. Alternatively, impregnation is performed by applying high pressure in a pressure cooker. In this way, the impregnating resin is applied to the entire surface of the thin wood veneer that has been subjected to shot blasting to give fine scratches and improved impregnation, so that the impregnating resin can penetrate into the inside of the thin wood veneer. Can do.

  And the floating process to form the concavo-convex part on the surface of the veneer may brush the surface of the veneer, but shot blasting improves the resin impregnation and improves the transparency. Although preferable, it is not limited to this.

  Here, the thickness of the spring portion 11a is preferably 0.05 mm or less, and the thickness of the autumn portion 11b is preferably about 0.05 mm to 0.5 mm. As a result, the color pattern on the surface of the printing layer 3 that has passed through the surface coat layer 9 is strong in the thin spring portion 11a, weak in the thick autumn portion 11b, or weak or inconspicuous. It becomes possible to make it appear on the surface in harmony with the color pattern.

  Here, when the thickness of the spring part 11a which is a concave portion exceeds 0.05 mm, it is unclear that the color pattern of the printing layer 3 is fused and harmonized with the color pattern of the decorative veneer 7 and appears as a new design appearance. It becomes. Further, when the thickness of the autumn part 11b, which is a convex part, is 0.05 mm or less, the appearance of the color pattern of the printed layer 3 becomes small in the spring part 11a and the autumn part 11b, and the cosmetic appearance is impaired. This is not preferable because the processing may be difficult.

  As a result, even if a veneer veneer having a low decorative property is used for the veneer veneer 7, the color pattern of the printed layer 3 and the color veneer of the veneer veneer are strong in the spring part 11a, and the autumn part In 11b, it becomes weak or can be blended and harmonized to such an extent that it is hardly noticeable.

  The blasting abrasive used in the above shot blasting treatment is made of, for example, glass beads, glass powder, inorganic particles such as silicon, metal particles such as alumina, hard organic particles pulverized with walnuts and peach seeds, or dry ice. Finely pulverized dry ice particles or the like are used.

  The particle size of the abrasive for blasting is preferably adjusted by a sieving method so as to be 90 μm or more and 150 μm or less. Thereby, while being able to make a fine damage | wound on the surface of a thin wood board by blasting, it can be set as the magnitude | size of the damage | wound which the above-mentioned impregnation resin tends to osmose | permeate.

  In the sieving method, sieving is performed in about 3 to 5 stages. The opening diameter of the first stage sieve is set to about 180 μm, the opening diameter of the second stage sieve is set to about 150 μm, and the opening diameter of the final stage sieve is set to about 90 μm. Thus, the blasting abrasive having a particle diameter of 90 μm or more and 150 μm or less is adjusted so as to contain about 70% or more of the whole. In addition to this, the abrasive includes a flat shape or an acute shape, or an abrasive having a particle size of 90 μm or less that cannot be passed.

  The blasting abrasive adjusted in this way is made to collide with the surface of the wood thin veneer that has been float-processed. The abrasive for blasting may be naturally dropped from the nozzle, or may be sprayed from the nozzle while applying pressure. A plurality of nozzles are arranged at arbitrary positions above the surface of the wood thin veneer so that the entire surface of the wood thin veneer is blasted.

  As shown in FIGS. 6 and 7, the manufacturing method of the decorative material A in Embodiment 2 is between the sticking step (Step S <b> 5 in FIG. 2) and the WPC treatment step (Step S <b> 6 in FIG. 2). 2 is the same as that of the first embodiment except that a float processing step (step S5 in FIG. 2) is provided. In FIG. 6, step S11 to step S18 are given in the order of the manufacturing process.

  In the second embodiment, as shown in FIG. 8A, the scanned digital image 11B of the pattern 11A of the decorative veneer 7 is darkened and printed on the base plate 1 to form the print layer 3. As shown in FIG. 8B, the decorative projecting plate 7 is stuck so that the picture 11 overlaps the digital image 11B. Alternatively, as shown in FIG. 8C, the decorative protrusion 7 is attached to the printing layer 3 darkened in FIG. 8A with the pattern 11 being displaced from the digital image 11B.

  In the second embodiment, in addition to the effect of the first embodiment, the decorative veneer 7 on the front side is formed to be uneven by the float process to express a three-dimensional effect. In addition to being able to make it stand out, in the recesses, the digital image 11B can be more visually recognized, and the cosmetic material A having a natural depth can be provided.

(Embodiment 3)
FIG. 9 shows a decorative material A according to Embodiment 3 of the present invention. This cosmetic material A is configured in the same manner as in the first embodiment except that the WPC processing step (step S6 in FIG. 2) is before the scanning step (step S1 in FIG. 2), and therefore only the differences will be described. The description of the same components will be omitted.

  In the manufacturing process of the decorative material A shown in FIG. 10, step S101 to step S107 are given in the order of the manufacturing process.

  In the third embodiment, as shown in FIG. 12A, the digital image 11B of the scanned pattern 11A of the decorative veneer 7 is subjected to a lightening process and a roughening process, and this is printed on the base plate 1 to obtain a print layer. 3, and as shown in FIG. 12 (b), the decorative veneer 7 is stuck so that the picture 11 overlaps the digital image 11 </ b> B. Alternatively, as shown in FIG. 12C, the decorative protrusion 7 is attached to the printing layer 3 that has been subjected to the lightening process and the coarse pixelation process in FIG. 12A with the pattern 11 shifted from the digital image 11B.
