平滑化した後、接着剤を介して化粧シートをプレ
スしてラミネートするものである。 Conventionally, the manufacturing method of decorative laminates made of wood-based substrates requires a step of polishing the surface of the wood-based substrate in order to enhance the design effect of the surface, and in some cases, there is a process of polishing the surface of the wood-based substrate. It requires processes such as applying a filler mainly made of resin and extender pigments, polishing the surface after drying, and after smoothing the surface of the decorative board, press the decorative sheet with an adhesive. It is then laminated.
しかし、木質系基材表面を研磨して平滑化する

な傷を付けることにもなり、研磨材を木材の種類
によつて選択しなければならないと云う不便もあ
る。 However, when polishing and smoothing the surface of a wood base material, it is difficult to obtain a uniform surface depending on the abrasive material used, and with soft wood base materials, it may cause fatal scratches on the surface. However, there is also the inconvenience that the abrasive must be selected depending on the type of wood.

る。 In addition, when forming a filler based on synthetic resins and extender pigments on the surface of wood-based substrates, it takes a long time to dry because synthetic resins such as nitrocellulose, alkyd, and urethane are used. death,
As a result, it is impossible to employ a continuous manufacturing method using a consistent manufacturing line including a polishing process.
そのため、近年体質顔料に紫外線硬化型樹脂を

表面が黄変し化粧板の意匠的効果を著るしく損う
と云う欠点がある。 For this reason, in recent years, a mixture of extender pigments and ultraviolet curable resins has been applied to the surface of wood-based substrates, irradiated with ultraviolet rays, cured in a few seconds, and then surface polished. However, this method has the disadvantage that the surface of the decorative board turns yellow due to the monomer remaining in the porosity of the wood, which significantly impairs the decorative effect of the decorative board.

得ることができた。 As a result of research to improve the above-mentioned conventional drawbacks, the inventor of the present invention omitted the conventional surface polishing process as well as the process of applying and drying a plugging agent by adopting the configuration described in the claims. However, we were able to obtain a method that allows continuous production of decorative laminates with excellent design effects.

表面に軟化溶融物４として析出する。 In general, wood composition is mostly composed of cellulose, hemicellulose, lignin, etc., of which 2 to 10% contains resin and oil.Such resin and oil are particularly abundant in South Sea wood, such as teak. However, when the wood base material 3 is heated and pressurized by the first metal roll 1a and the back-up roll 1b as described above, the wood content is increased. In the base material 3, especially the metal roll 1a
On the side in contact with the metal roll 1a, resins and oils and fats contained in the wood composition are precipitated as a softened melt 4 on the surface by heating and pressurizing the metal roll 1a.

油脂分の層５を形成する。 The softened molten material 4 deposited on the surface of the wood base material 3 as described above is transferred between the second metal roll 2a and the back up roll 2b as the wood base material 3 moves along the production line (l). , the softened molten material 4 precipitated on the surface of the wood base material 3 is spread thinly on the surface of the wood base material 3 by the heating and pressure of the second metal roll 2a, and the surface of the wood base material 3 is A resin component that fills porous areas to make them non-porous and has a smooth surface.
A layer 5 of oil and fat is formed.

しい。 Furthermore, the first metal roll 1a and the second metal roll 2a each have a mirror surface with a chrome-plated outer peripheral surface, are hollow inside, and are heated by an oil heating circulation method, a low frequency generating coil heating method, etc. While heating the surface, back up rolls 1b and 2
b. In this case, the heating temperature of the first metal roll 1a and the second metal roll 2a is 200°C.
If the rolling force is 5 kg/cm or less, the amount of resin and oil contained in the wood base material 4 will be small, and if the temperature is 250°C or higher, the cellulose of the wood base material will be reduced. , hemicellulose, lignin, etc. may be thermally decomposed and the original functions of the wood base material may be lost.
If the heating temperature exceeds 200 kg/cm, the wood base material will be compressed and problems such as thickness errors and warping will occur.
Preferably, the temperature is 250° C. and the rolling force is 5 to 100 kg/cm.

することができる。 The surface of the wood base material 3 obtained in the above manner not only loses the porosity peculiar to wood and becomes non-porous, but also becomes non-porous by heating and pressurizing the second metal roll 2a having a mirror surface. Highly smooth resin component,
The product in which the fat layer 5 is formed can be easily manufactured in a short time. Wood-based base material obtained from bamboo shoots 3
can be used as is as interior materials such as flooring and wall materials.

If necessary, two or more metal rolls, a first metal roll and a back-up roll paired with the first metal roll, may be used to precipitate resin and oil from the wood base material. It is also possible to arrange two or more pairs of a back-up roll and a second metal roll for smoothing the oil and fat to form a layer of resin and oil.

ため従来の如き接着剤の塗布工程は必要でない。 As mentioned above, the decorative sheet that is laminated to the surface of the wood base material is not only easy to paste because the surface to which the wood base material is laminated is non-porous and extremely smooth. Or, a layer 5 of resin and oil is formed on the bonding surface of the wood base material.
Since this plays the role of an adhesive for the decorative sheet, adhesion can be achieved without the need for any particular adhesive for bonding, so a conventional adhesive application process is not necessary.

始めとする各種化粧板に巾広く利用できる。 As described above, in the production of decorative laminates using wood-based substrates, the present invention heats and pressurizes the resins and fats and oils in the wood composition inherent in the wood-based substrates to precipitate them on the surface. Heating the precipitated resin and oil,
It is possible to form an extremely smooth layer by applying pressure and spreading it on the surface, and since this layer is used as an adhesive and a decorative sheet is attached to the surface, there is no need for conventional polishing of the surface of the wood base material. Moreover, there is no need for processes such as applying a sealant mainly composed of synthetic resins and extender pigments and the accompanying surface polishing, which greatly simplifies the process and provides benefits. The surface of the decorative board is non-porous, highly smooth and beautiful, and can be used for various decorative materials such as flooring, wall and ceiling materials, various interior materials, furniture materials, etc. Can be used in a wide range of boards.

ため、連続的に化粧板を製造することができる。 Moreover, the present invention arranges a pair of rolls consisting of at least two or more metal rolls and a back roll on the production line to precipitate the resin content and oil content in the wood base material on the surface, and then the precipitated resin minutes,
Since the oil and fat content can be smoothed out sequentially, there is no need for the long drying process that accompanies the application of fillers, etc. as in the past, and decorative sheets can be laminated continuously, allowing the continuous application of decorative sheets. can be manufactured.
