Field of the Invention The present invention relates to a decorative board coated with a composite sheet composed of a metal foil, a synthetic resin sheet and a paper, which is made of wood board such as plywood or wood medium density fiber board (hereinafter referred to as MDF). . More specifically, by coating a specific composite sheet, moisture permeation from the composite sheet layer is completely stopped, dimensional stability is greatly improved, and the time required for adhesion is significantly increased when bonding with other wood. The present invention relates to a wooden decorative board that can be used with an acid / alkali adhesive used for shortening.

ャビネットが反るなどの不具合が生じていた。The method of compounding the metal foil inside the wood fiber layer or wood shaving layer has the drawbacks that it is difficult to cut with a woodworking machine or shortens the life of the blade, and the size of the wood fiber is stable. There is no effect to make it. Further, in the method of coating the composite sheet of aluminum foil and paper, the aluminum foil having a thickness of 25 μ or less has pinholes, so that moisture permeation cannot be completely prevented, or vinyl acetate type, α -If an olefin adhesive with strong acid / alkali is used, it has the advantage that the time required for normal bonding will be shortened, but the acid / alkali will deteriorate the adhesive layer between the paper and aluminum, and prevent moisture permeation. There was a problem that performance deteriorated. Furthermore, with the method of covering the synthetic resin sheet, the synthetic resin sheet that can be used for woodworking cannot completely prevent moisture permeation, and when 6 months to 1 year has actually passed, the inside of the panel due to temperature changes Due to the movement of water, the absorption of moisture in a high humidity environment and the release of moisture in a dry environment, problems such as warping of interior doors and cabinets have occurred.

The synthetic resin at that time is preferably polyethylene or an ionomer having good workability. Furthermore, in the case of heat-sealing polyethylene, the adhesive strength between the metal foil and polyethylene remarkably varies depending on the amount of heat and line speed at the time of extrusion, which may easily cause interfacial peeling between the metal foil and polyethylene. In the case of industrial use, it is necessary to provide a primer layer between the metal foil and the synthetic resin sheet so that the adhesive strength is stable and strong.

させるなどの問題が生じる。The thickness of the composite sheet of the present invention is not particularly limited, but it is possible to work without hindrance in the bonding process with a wood base material, and from the viewpoint of adhesive strength with other wood, 40 to 200 μm.
It is preferred that If the thickness is less than 40 μm, the sheets may be broken during the laminating process. For example, in the case of a sheet composed of a metal foil 6 μm, a synthetic resin sheet 10 μm and a paper 23 μm, the paper layer portion is thin, and therefore the layer through which the adhesive penetrates. Is too thin to have sufficient adhesive strength. 20
If it exceeds 0 μ, it will be difficult to cut the sheet in the process after bonding it with the wood base material, or if the paper layer becomes thick, the paper-to-paper strength will decrease significantly, so that it will not be combined with other wood. When the adhesive strength after bonding becomes insufficient and the synthetic resin layer is to be thickened, the extrusion laminating speed must be slowed, which causes a problem such as a decrease in production efficiency.

を受ける結果となり、実際の作業工程で混乱を来す。The thickness of the synthetic resin film or the synthetic resin coating layer is not particularly limited, but it has a function of preventing moisture permeation.
It is preferably from 00 to 200 μ. In particular, the present invention is characterized in that it is a decorative board in which a composite sheet having a three-layer structure composed of a metal foil, a synthetic resin sheet and paper is laminated on a wooden base material. The paper layer, which is one layer of the three-layer composite sheet, is for the conventional use of the water-based adhesive that is mainly used in this industry at the time of adhesion with other wood. Therefore, it is desirable that the reinforcing paper be used. Further, the metal foil layer has a function of preventing moisture permeation, but especially in the case of aluminum which can be rolled into a thin foil, pinholes cannot be avoided when the thickness is 25 μm or less when used alone, and complete moisture resistance cannot be obtained.
Specifically, it is known that it has a maximum moisture permeability of about 1 g / m 2 at a thickness of 9μ, and it cannot completely prevent moisture permeability, which is a part particularly contributing to dimensional stabilization of the wood base material. become. Furthermore, when using an acid / alkaline adhesive that has the effect of shortening the time required for adhesion when adhering to other wood, it may corrode metal foil, corrode metal foil,
There are problems that the adhesive strength between the metal foil and the paper is deteriorated, the adhesive strength is significantly reduced, and the moisture permeation resistance is reduced. When a metal with a thickness of 25 μm or more is used, moisture permeability can be completely prevented, but it is difficult to cut with a conventional woodworking blade, and as with the above, an acidic or alkaline adhesive agent when bonding with other wood. Will be unusable and will be severely limited, confusing in the actual working process.

We have found that the problem can be solved by compounding synthetic resin layers to fill the pinholes during rolling. Furthermore, by inserting a resin layer between the paper cover and the metal foil layer, it was possible to bond it to other wood using an acidic or alkaline adhesive, and succeeded in significantly increasing the production efficiency.
