  By the way, when peeling a decorative sheet, the one described in Patent Document 1 is indispensable to use an adhesive containing a special material such as a thermally expandable fine particle hollow body or to heat a decorative sheet-attached wood board. Incurs high costs and is cumbersome. Moreover, since the thing of patent document 2 is indispensable for the heating of a decorative sheet pasting wood board material, since the thing of patent document 3 is providing water to a decorative sheet pasting wood board material, it is indispensable. Both are cumbersome.

  On the other hand, in the case where the decorative sheet can be peeled by hand, the surface of the wooden substrate after peeling may be fluffy and rough, while not requiring the troublesome work described above. For example, when a decorative sheet is newly applied to the peeling surface of a wooden base material obtained by peeling, the surface properties of the wooden base material are very important, and the surface is fluffy and rough as described above. May be reflected in the appearance of the decorative sheet to which is attached, and the appearance may be impaired. Therefore, when the surface of the wooden substrate after peeling is rough, this wooden substrate is made into chips, for example, and further effective utilization of resources cannot be achieved.

  Therefore, the present invention does not require a special process for peeling the decorative sheet, and a method for reusing a decorative wooden sheet material with a decorative sheet that can cope with the roughness of the surface of the wooden substrate after peeling. The issue is to provide.

  In order to solve the above problems, the present invention is configured as follows.

  First, the invention according to claim 1 is a method of reusing a wooden sheet material with a decorative sheet attached to at least one surface, and a decorative sheet is not attached to at least one surface. Then, a decorative sheet is newly affixed to a surface on which the decorative sheet of the wooden base material obtained by peeling the decorative sheet from the decorative sheet-attached wooden board is not affixed.

  Next, the invention according to claim 2 is the method for reusing a decorative sheet-attached wood board material according to claim 1, wherein when the decorative sheet is newly affixed to the wooden substrate, the end of the decorative sheet is provided. The part is attached to the side end of the surface of the wooden substrate obtained by peeling the decorative sheet.

  According to a third aspect of the present invention, in the method for reusing a decorative sheet-attached wood board material according to claim 1 or 2, the cosmetic sheet-attached wood board material is separated from the decorative sheet-attached wood board material before the decorative sheet is peeled off. The edge part of a sheet pasting wood board material is excised together with a decorative sheet, It is characterized by the above-mentioned.

  First, according to the first aspect of the present invention, when the decorative sheet is peeled from the decorative sheet-attached wood board using a hand or a simple tool such as a cutter or a spatula, the thermoplastic sheet is heated or the decorative sheet is used as in the prior art. There is no need for special processes such as the application of water to the pasted wood board. In addition, even if the peeling surface of the wood base material obtained by peeling the decorative sheet is fuzzy and rough, the decorative sheet is newly applied to the surface where the decorative sheet has not been applied. A decorative sheet-attached wood board without damage is obtained, and thus the wood substrate obtained by peeling the decorative sheet can be reused in the production of the decorative sheet-attached wood board. That is, it is not necessary to chip the wood substrate as in the conventional case, and further effective utilization of resources can be achieved.

  Next, according to the second aspect of the present invention, when a decorative sheet is newly affixed to the wooden base material obtained by peeling the decorative sheet, the decorative sheet is peeled off at the end of the decorative sheet. As a result, the side edge of the fuzzy and rough surface is pasted and pasted, so the side edge only has to maintain the quality between the decorative sheet and the wooden substrate due to the roughness described above. Adhesive strength can be obtained, and when the decorative sheet is peeled again from the decorative sheet-attached wood board thus produced, the decorative sheet can be peeled without taking time and effort.

  And according to invention of Claim 3, before peeling a decorative sheet from a decorative sheet pasting wood board material, since the edge of this decorative sheet pasting wood board material is also excised together, a decorative sheet is, Since not only the front surface but also the adjacent side surface, the back side edge or the grooved part formed on the side surface, it is pasted to the concave groove processing part. By excising the part, a clue for peeling the decorative sheet by hand is formed, and the decorative sheet can be peeled more easily.

  Hereinafter, a method for reusing a decorative sheet-attached wood board according to an embodiment of the present invention will be described.

  As shown in FIGS. 1 and 2, this decorative sheet-attached wood board 1 has a thin-walled decorative sheet 20 attached to a surface 11 of a wooden substrate 10 having a rectangular cross section via an adhesive layer 30. The decorative sheet 20 is not attached to the back surface 12, the both side surfaces 13, 13, and both end surfaces (only the front side is shown in FIG. 1) 14,14. In this case, the wood substrate 10 is made of MDF (medium density wood fiberboard), and the decorative sheet 20 is made of polypropylene resin. The adhesive layer 30 is obtained by curing a moisture-curing polyurethane resin adhesive, and the decorative sheet 20 can be peeled off with a simple tool such as a hand, a cutter, or a spatula. It is affixed to the wooden substrate 10 via the layer 30.

  Next, a method of peeling the decorative sheet 20 from the decorative sheet-attached wooden board material 1, newly attaching the decorative sheet 20 to the obtained wooden base material 10, and reusing the decorative sheet-attached wooden board material 1 will be described. To do.
