Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a chemical J)I having a three-dimensional block pattern on its surface, which is suitable for building materials such as wall materials, various furniture surface materials, and other decorative boards.
, relates to a plate and its manufacturing method.

Traditionally, to manufacture this yuzu decorative board, as shown in Figure 2, adhesive is applied to plywood (a), and then veneer (b) is manufactured.
There is a known method in which the veneer is polymerized and bonded, and then grooves (d) are cut in the desired pattern using a router (C) on the surface of the veneer, and the surface is then painted. Since cutting is required, the cutting time is long, and the productivity is low for forming complex patterns.Furthermore, only a monotonous Batashi pattern can be obtained.

Another method is to arrange and glue multiple heathers, which have been chamfered in advance, on plywood coated with adhesive in a parquet style, but it is necessary to create a uniform arrangement pattern of heathers on a large number of baseboards. It was difficult to do this, causing the product to come apart, and since the heath was chamfered, the adhesive oozed out from the joints between the heathers, impairing the cosmetic properties. .

In order to eliminate such drawbacks, the present invention arranges and fixes a plurality of veneer heathers in a square pattern on plywood via an adhesive sheet made of a thermosetting resin-impregnated sheet, and also fixes the blocks. The shaped pattern can be obtained by preparing a desired block-shaped printed pattern on the surface of the adhesive sheet in advance, and arranging a veneer heather of a size that matches the shape of each part of this printed pattern.・The present invention provides a decorative board and a method for manufacturing the same, characterized in that the veneer heather is bonded to the plywood via an adhesive sheet by heating and pressurizing the veneer heather placed on top together with the plywood. be.

To explain the embodiment of the present invention with reference to the drawings, plywood (1)
An adhesive sheet 1-(2) consisting of a thermosetting resin-impregnated sheet is placed on top.
) through multiple decorative veneer pieces (8) (3) −
--- When arranging (3) in combination in an O-shaped pattern, a sheet with a block-shaped pattern printed (4) on its surface in advance is used as the adhesive sheet (2),
As the decorative veneer heather (3), use is made of a veneer having an appropriate thickness cut into desired shapes and dimensions that match the respective portions (4a) (4 and b) of the printed pattern (4).

For example, if the printed pattern (4) is a ':50-shaped pattern that is a combination of a rectangular pattern part (4a) and a triangular pattern part (4/b) as shown in the figure, the rectangular pattern part (4a)
) with the same shape matching the veneer heather (3a) and the same shape matching the triangular pattern part (4b) with the same shape veneer heather (3a)
(b) are prepared in advance for multiple copies.

Further, the edges on the front side of these single heathers (3) are chamfered into a desired cross-sectional shape to form an inclined end surface (5). This inclined end surface (5) is provided on all four sides, that is, on the entire circumference or on any of the four sides, and its cutting shape may be a planar cut at an angle of Ils degrees in the vertical direction, a rounded one, or a stepped one. Various end face shapes can be adopted, such as those in which a portion is formed.

On the back side of each veneer piece (8) formed in this way, an adhesive substance (6) such as a rubber adhesive is applied in spots on the part excluding the outer periphery, and then an adhesive sheet (2) is applied. Temporarily adhere veneer heathers (aa) (3b) in shapes that match the printed pattern (4) (4a) and (4b) to the respective pattern parts (4a) and (4b) using an adhesive substance (6). do. At this time, since the adhesive substance (6) is not applied to the outer periphery of the veneer heather (3), it will not ooze out from the joints when arranged into the printed pattern (4).

Note that the adhesive sheet (2) used is, for example, paper impregnated with a thermosetting resin such as Merasanshi resin and dried.

Next, the adhesive sheet (2) is placed on a plywood (1) having substantially the same planar shape as the adhesive sheet (2).

In this case, for ease of work, the construction work of the veneer heather (8) for the printed pattern ←) of the adhesive sheet (2) described above is done after placing the adhesive sheet (2) on the plywood (1). However, there is no problem even before it is placed.

In this way, the adhesive sheet (2) is placed on the plywood (1),
After arranging the veneer heather (3) in a square pattern on the surface of the adhesive sheet (2), it is inserted between the upper and lower hot plates of the hot press (7) and heated and pressurized to form the adhesive sheet. (2
) thermosetting resin is softened and melted to form each veneer heather (
3) and the surface of the stand m(1) and hardens in that state so that the veneer heather (3) is integrally bonded to the plywood (1) via the adhesive sheet (2).

After that, the surface of the veneer heather (3) fixed on the plywood (υ) is treated with a sashijijishiji treatment after being arranged into a block-like pattern, and then the surface is finished by painting.

As described above, in the present invention, an adhesive sheet made of a thermosetting resin-impregnated sheet with a block-like pattern printed on its surface is placed on a base plate, and then the end surface is cut into an appropriate chamfer shape and the block-like pattern is cut. A plurality of veneer heathers formed in a size that matches the shape of each part of the pattern are placed and fixed in accordance with each part of the Otsuk-shaped pattern, and then plywood and adhesive sheets are attached.]
・As this relates to a method for manufacturing a decorative board, which is characterized by heating and pressing veneer pieces together and bonding a veneer heather onto plywood via an adhesive sheet, the surface of the adhesive sheet is preliminarily coated with 0. A tsuk-like printed pattern is provided, and veneer heathers of a size that matches the shape of each part of this printed pattern are placed on top of the printed pattern, making it possible to work on the veneer easily and accurately, and to achieve uniform work. It is suitable for the mass production of decorative laminates with three-dimensional block-like patterns, and even with complex block-like patterns, the veneer heather can be simply placed to match the pattern, making it easy to assemble. It is possible.

In addition, since the groove spacing between the veneer heathers can be set appropriately using the O-shaped printed pattern, a three-dimensional appearance with rich design can be obtained, and the groove bottom is covered with an impregnated sheet layer, making it beautiful. Furthermore, since the adhesive sheet is made of a thermosetting resin-impregnated sheet, it is possible to firmly integrate the veneer heather on the plywood through the adhesive sheet by applying heat and pressure. Since the adhesive does not ooze out between the veneer heathers, a decorative board with a good appearance can be obtained.

In addition, when assembling veneer heathers on an adhesive sheet, temporary adhesion can be achieved by applying an adhesive substance to the back side of the heathers, making it easier to handle without shifting the arrangement pattern of the veneer heathers, and making it easier to handle by heat pressure bonding. It is possible to maintain an accurate pattern even when printing.
