た。[Prior art] Conventionally, to attach thick decorative veneer pieces with a thickness of 1 mm or more on a substrate such as plywood in a mosaic pattern, the veneer veneer will warp and warp when it dries. Since it is easy to occur, after cutting a wet veneer into a desired shape, it is hot-press bonded so that it is lined up on the substrate, or sometimes pre-cut wood is glued together in a pattern and cut to a predetermined thickness. The decorative veneer thus obtained is hot-pressed onto a substrate.

製造方法に係る。[Means for Solving the Problems] The present invention has been made to solve the above-mentioned conventional problems, and has a configuration in which a separate coating type high-setting adhesive comprising a primer and a main agent is formed on the surface of a sheet-like material. After applying either the primer or the main agent of the agent, on the other hand, applying one of the main agent or the primer which is a pair with the adhesive applied to the sheet-like material on the back surface of the thick dry veneer piece,
The thick dry veneer piece is placed on the adhesive applied surface of the sheet-like material in a desired pattern shape so as to be in contact with the adhesive applied surface,
Then, they are pressed for a short time by a pressing device and temporarily bonded to form a decorative piece, and then the sheet-like surface of the decorative piece is placed on a substrate having a surface coated with an adhesive mainly composed of a thermosetting resin. The present invention relates to a method for manufacturing a decorative board in which a decorative plate is bonded by hot-pressing a substrate and a decorative piece.

ない。[Operation] In the present invention, a thick dry veneer piece 2 is adhered to the sheet-like material 1 with a high-setting adhesive 3 and then hot-press bonded to a substrate 7 using a conventional thermosetting adhesive 6. The reason for this is to make it easier to handle the veneer pieces 2 and to prevent the occurrence of cracks and gaps due to drying shrinkage of the veneer pieces 2 by using a dried veneer. Further, the sheet-like material 1 is interposed between the substrate 7 and the thick veneer 2 to prevent the veneer 2 from drying due to a difference in expansion and contraction between the veneer 2 and the substrate 7 due to a change in humidity in the air. That's why. Furthermore, since the sheet-like material 1 is interposed between the substrate 7 and the thick veneer piece 2, there is no need to grind and remove it.

The primer of the adhesive 3 was applied at a rate of 50 g / m 2 on the surface of No. 1 and dried for about half a day, and then placed so that the adhesive 3 application surface was in contact with the adhesive 3 application surface of the veneer 2. Next, it is inserted between the pressing belts 5 moving in parallel up and down, and
It was pressed with a slight pressure of about g / cm 2 , and the veneer 2 and the thin paper 1 were temporarily bonded to form a decorative piece.
