Description of the Related Art Conventionally, as a composite decorative board having scratch resistance and dry cracking resistance, there is a form in which a veneer made of a decorative veneer is stuck on a plywood. When used as a material, the surface of the floor material was scratched by casters or the like. For this reason, as shown in FIG. 2, as another composite decorative board 50, an MDF (medium fiber board) 51 having a hard surface is interposed on the lower surface of the veneer 52, for example, an MDF 51 having a thickness of 2.7 mm. A composite decorative board 50 having a 12 mm-thick MDF composite base material 54 made of a 9 mm-thick plywood 53 is manufactured. Reference numeral 55 denotes warpage preventing paper, and reference numerals 56 and 57 denote male and female fruits.

料等により塗装仕上げする。Next, a method of manufacturing a composite decorative board 10 according to one embodiment of the present invention will be described with reference to FIG. A thin fiberboard 12 having a thickness of 1.35 mm is manufactured by slicing a 2.7 mm thick MDF into two pieces.
When a 2.7 mm MDF is applied to the cutter to make a thin cut, a feed roll is applied to the surface of the MDF. However, since a convex portion is formed on the roll surface to prevent slipping, a thickness of 1 mm is formed by the convex portion. On the surface of the .35 mm thin fiberboard 12,
During slicing, fine flaws occur in the slicing direction.
Next, when manufacturing a plywood as a wood substrate, the above-mentioned thin fiberboard 12 having a thickness of 1.35 mm as an alternative to a veneer face is used.
The composite base material 17 is manufactured by hot pressing at a time through an adhesive made of a thermosetting resin. Further, the kraft paper 14 and the decorative veneer 13 are sequentially laminated and bonded on the thin fiber board 12 of the composite base material 17 with another adhesive. Thereafter, if necessary, the surface of the decorative veneer 13 is painted with a urethane resin paint or the like.

したものを使用すると、より平滑になり好ましい。In other words, fine flaws formed on the surface layer of the thin fiberboard 12 appear slightly when the decorative veneer 13 is adhered and painted. The thin veneer board 12 is adhered so that fine flaws formed on the surface layer of the thin fiberboard 12 do not affect the decorative veneer 13. Further, by making the papermaking direction of the kraft paper 14 perpendicular to the fiber direction of the veneer veneer 13, the concave portion due to the flaw of the thin fiberboard 12 can be made inconspicuous, and the veneer veneer 13 can also be cracked. In addition, for the adhesion between the composite base material 17 and the kraft paper 14, it is preferable to use a compound in which an anti-fogging agent (compounding inorganic carbon carbide or the like) of the adhesive over time is blended for smoothness.

できる。According to the composite decorative board of the first and second aspects and the method of manufacturing the composite decorative board of the third and fourth aspects, a thin fiberboard obtained by thinning a fiberboard on the surface of a wooden substrate. Since it is used, it has scratch resistance and dry cracking resistance and can produce a composite base material at low cost. Further, since the thin fiberboard and the veneer are laminated and bonded via the paper material, the influence of the flaw formed on the surface of the thin fiberboard on the veneer can be suppressed. In particular, in the composite decorative board according to the second aspect and the method for manufacturing the composite decorative board according to the fourth aspect, since the papermaking direction is orthogonal to the fiber direction of the veneer, the concave portion due to the flaw of the thin fiberboard. Can be made less noticeable.
