用い、前記積層模様により意匠性を向上させようとする
のが一般的であった。Decorative boards used for finishing the interior / exterior of buildings, furniture, fittings, etc. are required to have high designability. Therefore, usually, thinly sliced on the surface of a substrate such as plywood that constitutes a decorative board, laminate a veneer with a natural pattern or color such as beautiful wood grain to enhance the design effect, or even laminate and bond multiple pieces of wood. An attempt is made to improve the designability by using the laminated flitch that is formed by thinly slicing the laminated pattern in the direction in which the laminated pattern appears on the substrate and overlaying it on a substrate such as plywood as a decorative plate. Was common.
さらに最近では、これら平面的な意匠のみならず立体的
な美観に対する要求が強くなり、突板を合板等の基板上
にオーバーレイしてなる化粧板に対しエンボス等の凹凸
加工を施そうとする試みがなされるようになってきた。More recently, the demand for three-dimensional aesthetics as well as these two-dimensional designs has become stronger, and attempts have been made to apply unevenness processing such as embossing to a decorative board formed by overlaying a veneer on a board such as plywood. It has come to be done.

法である。The present invention is an embossing decorative plate original plate characterized in that a veneer is laminated on a substrate via an adhesive containing a water-absorbing polymer, and the embossing is applied from the veneer of the original plate. This is a decorative board. At this time, it is more preferable to carry out the object of the present invention if the embossing is performed at the same time as the pressure bonding of the projecting plate to the substrate. Furthermore, the present invention is a method for producing a decorative board, which comprises laminating a veneer on a substrate coated with an adhesive containing a water-absorbent polymer, and then performing embossing on the veneer.

て形成する。The veneer is a thin slice of wood such as oak, teak, cherry blossom, elm, or a flitch made by laminating wood pieces such as oak, teak, cherry blossom, elm, etc. appropriately laminated to obtain a desired design in its cross section. , Sliced thinly to form.
前記突板を前記基板に積層接着する際に用いられる接着
剤中としては、具体的には例えば、水性ビニルウレタン
系接着剤、ユリアメラミン樹脂混合物等の接着剤中に、
あらかじめ水を10〜300倍、より好ましくは10〜200倍、
吸収させた吸水性ポリマーを接着剤100部に対して10〜1
00部添加したものが用いられる。The adhesive used when laminating the veneer to the substrate is specifically, for example, an aqueous vinyl urethane adhesive, an adhesive such as a urea melamine resin mixture,
Water in advance 10-300 times, more preferably 10-200 times,
Absorbed water-absorbent polymer 10 to 1 to 100 parts of adhesive
The one added with 00 parts is used.
前記吸水性ポリマーに吸収させる水の量が10倍より少な

ーによる保持を離れたフリーな水分が現れ、一般にパン
クと言われる現象、すなわち接着不良が起こりやすくな
り、また突板表面からの接着剤のしみ出しが激しくなる
ので好ましくない。When the amount of water absorbed by the water-absorbent polymer is less than 10 times, the water-holding amount of the water-absorbent polymer is insufficient, the viscosity of the adhesive increases, and the veneer easily breaks during embossing. Further, when the amount of water is more than 300 times, free water appears apart from the retention by the water-absorbing polymer, a phenomenon generally called puncture, that is, adhesion failure easily occurs, and the adhesive stains from the veneer surface. It is not preferable because the feeding becomes violent.
吸水性ポリマーとしては、架橋ポリアクリル酸ソーダ、
デンプンアクリル酸グラフト重合体、酢酸ビニル・アク
リル酸メチル等を用いることができる。As the water-absorbent polymer, crosslinked sodium polyacrylate,
Starch acrylic acid graft polymer, vinyl acetate, methyl acrylate, etc. can be used.

板表面に80〜130g/m2塗布し、突板を該接着剤上に載置
し、８〜25kg/cm2、105〜120℃で、１〜３分間、加熱圧
着して前記突板を前記基板に積層接着する。An adhesive containing the water-absorbing polymer is preferably applied to the surface of the substrate at 80 to 130 g / m 2 and a veneer is placed on the adhesive, at 8 to 25 kg / cm 2 , at 105 to 120 ° C. The veneer plate is laminated and adhered to the substrate by thermocompression bonding for 3 minutes.
加熱圧着にはホットプレスを用いるが、突板と基板との
積層接着と同時にエンボス加工を行う場合には、プレス
面にエンボス型を有するものを使用する。A hot press is used for thermocompression bonding, but when embossing is performed at the same time as the laminated plate and the substrate are bonded together, a press surface having an embossing die is used.

板等がその水分によって柔軟になり、凹凸模様ができや
すくなり、突板等の破れも防止できる。According to the embossed decorative plate and the method for manufacturing the same of the present invention, since the veneer is laminated on the substrate via the adhesive containing the water-absorbing polymer, the veneer is heat-pressed and bonded with the embossed plate. At this time, the water-absorbent polymer contained in the adhesive is compressed, and the absorbed water comes out, and the veneer and plywood are softened by the water, making it easier to form an uneven pattern and preventing the veneer from breaking. .
以下に本発明の実施例について詳述する。 Examples of the present invention will be described in detail below.
〈実施例１〉 ナラ材を薄くスライスして突板を準備する。<Example 1> A veneer is prepared by slicing oak into thin pieces.

し、20kg/cm2,120℃で、２分間加熱圧締接着する。In order to perform embossing at the same time that the projecting plate is bonded to the substrate, an embossing flat plate having a concavo-convex pattern is placed on the projecting plate, and heat compression bonding is performed at 20 kg / cm 2 , 120 ° C. for 2 minutes.
このようにすることにより、突板が若干可塑性を帯び、
凹凸模様の綺麗な化粧板を得ることができる。By doing this, the veneer becomes slightly plastic,
It is possible to obtain a beautiful decorative plate with an uneven pattern.
〈実施例２〉 ナラ材を薄くスライスして突板を準備する。Example 2 A veneer is prepared by thinly slicing oak.

に綺麗な凹凸模様を有する美感に優れた化粧板を得るこ
とができる。As described above, the decorative plate of the present invention is poor in flexibility because the veneer is laminated on the substrate via the adhesive containing the water-absorbing polymer, and the veneer is embossed. Even with a veneer, an uneven pattern is likely to be formed, and the veneer does not break or break, so that it is possible to obtain a decorative plate having a beautiful uneven pattern and having an excellent appearance.

易に美しい凹凸模様を得ることができる。Furthermore, in the method for manufacturing a decorative board of the present invention, since the veneer is laminated on the substrate coated with the adhesive containing the water-absorbing polymer, the embossing is performed at the same time when the veneer is bonded to the substrate. When heat-pressing and adhering with a mold, the water-absorbent polymer in the adhesive is compressed, the absorbed water comes out, and the veneer and substrate become soft due to the water, so the veneer is not damaged and the embossed type It is possible to easily obtain a beautiful concavo-convex pattern by solving the problem in the conventional method that if the concavo-convex is forcibly made, the veneer is broken and the concavo-convex pattern cannot be cleaned.
