【発明の詳細な説明】
この発明は人工化粧単板の製造方法に関するものである
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing artificially decorated veneers.
人工化粧単板は、たとえば、木質単板を染色した後、接
着剤を介して積層し、これを凹凸型版などにより圧締し
て変形フリッチを形成し、適宜の方向にこれをスライス
して製造することができる。Artificial decorative veneers are produced by, for example, dyeing wooden veneers, laminating them with adhesive, pressing them together with a textured plate to form deformed flitches, and slicing them in appropriate directions. can be manufactured.
このようにして得られた人工化粧単板は、接着剤の層が
屈曲した木目状の柄となって表われ、天然の銘木のよう
な外観を呈したものとなるためこの製造方法は従来より
広く行われている。The artificial decorative veneer obtained in this way has a wood grain-like pattern with the adhesive layer bent, giving it the appearance of a natural precious wood. It is widely practiced.
ところが、この染色単板の積層に際してウレタン系の接
着剤を用いた場合、その接着剤の粘度が高いと単板に均
一に塗布し難く、またその粘度が低いと硬化時に発泡し
やすくなって接着剤の層に気泡が生じ化粧単板の外観を
低下させるという問題があり、また、この接着剤は染色
単板の水分によって硬化が促進されるために、それら染
色単板の積層を手早く行って堆積時間を短くする必要が
あり、したがって積層・プレスの枚数が制限されること
となり、厚みの大きいフリッチを形成することが困難で
生産性が低いという問題があった。However, when using a urethane-based adhesive when laminating dyed veneers, if the viscosity of the adhesive is high, it is difficult to apply it uniformly to the veneer, and if the viscosity is low, it tends to foam during curing, resulting in poor adhesion. There is a problem in that air bubbles form in the adhesive layer, degrading the appearance of the decorative veneer.Also, the curing of this adhesive is accelerated by the moisture in the dyed veneers, so the dyed veneers are laminated quickly. It is necessary to shorten the deposition time, which limits the number of sheets that can be laminated and pressed, making it difficult to form thick flitches and resulting in low productivity.
したがって、この発明の目的は、品質のすぐれた人工化
粧単板を能率よく生産することのできる方法を提供する
ことである。Therefore, an object of the present invention is to provide a method that can efficiently produce artificial decorative veneers of excellent quality.
この発明の特徴を第1図および第2図にもとすき説明す
る。The features of this invention will be explained in detail with reference to FIGS. 1 and 2.
すなわち、この人工化粧単板の製造方法は、単板の表面

高粘度のウレタン系接着剤を塗布して積層するとともに
圧締、接着してフリッチとし、このフリッチをスライス

150℃に加熱した熱ロール2でその表面だけを乾燥さ
せるとともに表面温度を20〜50℃にして引続き第2
図のように高粘度のウレタン系接着剤3をロールコータ
4で塗布する。That is, the manufacturing method of this artificial decorative veneer involves heating the surface of the veneer to 20 to 50°C with a hot roll to dry it, then applying a high-viscosity urethane adhesive, laminating it, and pressing it. , is glued to form a flitch, and this flitch is sliced. For example, as shown in Fig. 1, a dyed veneer 1
Adjust the moisture content to 80-100%, and
Only the surface is dried with a hot roll 2 heated to 150°C, and then the second roll is heated to a surface temperature of 20 to 50°C.
As shown in the figure, a high viscosity urethane adhesive 3 is applied using a roll coater 4.
そしてこの染色単板1を積層、堆積して凹凸型版でプレ
スしてフリッチとし、さらに適宜の角度でスライスして
人工化粧単板を得るのである。The dyed veneers 1 are then laminated and piled up, pressed with a concave-convex plate to form flitches, and further sliced at appropriate angles to obtain artificial decorative veneers.
この方法によれば、染色単板1の表面が20〜50℃の
温度に高められているため高粘度のウレタン系接着剤3
を用いてもその粘度が低下して染色単板1にむらな(均
一に塗布でき、硬化後の気泡の発生を防止できる。According to this method, since the surface of the dyed veneer 1 is heated to a temperature of 20 to 50°C, a high viscosity urethane adhesive 3 is used.
Even if it is used, its viscosity decreases and it becomes uneven on the dyed veneer 1 (it can be applied uniformly and the generation of bubbles after curing can be prevented).
また、この染色単板1は熱ロール2で表面が乾燥されて
いるため、ウレタン系接着剤3の水分による硬化促進作
用を生じることがなくなり、積層、堆積時間を延ばすこ
とができる結果、その積層枚数を増加して厚みの大きい
フリッチとすることができる。In addition, since the surface of this dyed veneer 1 is dried with a hot roll 2, the hardening effect of the urethane adhesive 3 due to moisture does not occur, and as a result, the lamination and deposition time can be extended. By increasing the number of flitches, a thicker flitch can be obtained.
さらに、フリツチとして圧締、接着するに際しては、染
色単板1の内部に残留している水分が圧締によって染色
単板1の表面に塗布されたウレタン系接着剤3の層まで
浸み出してくるため、その圧締と同時にウレタン系接着
剤3を速やかに硬化させることができる。Furthermore, when pressing and adhering as a frit, the moisture remaining inside the dyed veneer 1 seeps out to the layer of urethane adhesive 3 applied to the surface of the dyed veneer 1 due to the pressing. Therefore, the urethane adhesive 3 can be quickly cured at the same time as the pressing.
以上のように、この発明の人工化粧単板の製造方法は、
単板の表面を熱ロールで20〜50℃に加熱して乾燥し

人工化粧単板を能率よく生産できるという効果がある。As described above, the method for manufacturing artificially decorated veneer of this invention is as follows:
The surface of the veneer is heated to 20-50℃ with a hot roll and dried, then a high viscosity urethane adhesive is applied and laminated, pressed and bonded to form a flitch, and this flitch is sliced. Because of this feature, it is effective in efficiently producing high-quality artificial decorative veneers.
