Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a laminated board used as a surface material or a decorative material in interiors of buildings, furniture and the like.

[0002]

[Prior Art]

 For this type of application, plywood or a laminate of veneer or decorative sheet such as decorative paper on the surface thereof is widely used.

[0003]

[Problems to be solved by the device]

 However, since plywood is manufactured by laminating and bonding veneer from which natural wood is thinly peeled, the depletion of natural resources has become a global problem, and it has become increasingly difficult to cut down the raw material raw wood. There is.

Further, since the quality of the raw wood is deteriorated, it is becoming difficult to obtain a large amount of good quality veneer to be used for the front veneer. If it becomes impossible to use good-quality veneer on the surface of plywood, defects on the surface of plywood will be exposed through the decorative sheet that adheres to the surface, which will significantly reduce the commercial value.

Further, since it is difficult to obtain the same material color for the surface veneer of the plywood, the material color appears on the surface through the makeup sheet, and the designability is deteriorated.

The defects on the surface of the plywood and the appearance of the material color through the decorative sheet can be solved by increasing the thickness of the veneer or the decorative paper used as the decorative sheet, but this is not preferable because it causes an increase in cost.

[0007]

[Means for Solving the Problems]

 Therefore, the present invention was devised with the object of eliminating the above-mentioned drawbacks of the prior art, in which a wood fiber obtained from a softwood material is provided on the surface of a composite board formed by sticking a veneer made of natural wood A laminated board characterized in that a surface board made of a board or a wood chip board is laminated and adhered.

The composite board is formed by sticking a single board made of natural wood, and specifically, a plywood or a single board laminated board is used.

The number of laminated single plates is arbitrary. For example, a plywood obtained by sticking an odd number of veneers so that the fiber directions thereof are orthogonal to each other can be used as a composite plate. Will be obtained. Further, a veneer laminated plate obtained by adhering an even number of veneers so that the fiber directions thereof are orthogonal to each other can be used as a composite plate. A laminate of sheets will be obtained.

Further, the composite plate itself shown in the above may be laminated and adhered to the composite plate of the present invention. For example, three 3-ply plywoods can be laminated and bonded, or two 5-ply plywoods can be laminated and bonded to form a composite plate.

The surface plate laminated and adhered to the surface of the composite plate is made of a wood fiber plate or a wood shaving plate obtained from a softwood material. That is, hardwood, MDF, insulation board and other wood fiberboard obtained by press-molding wood fibers obtained by defibrating wood chips obtained by cutting softwood logs, or cutting softwood logs. It is a wood chip plate such as a particle board, an OSB, or a wafer board obtained by press-molding the resulting chip, flakes, or strand wood chips.

The thickness of the face plate is generally 0.5-5 mm, but is not critical.

The surface plate may be coated and impregnated with a synthetic resin by using a coating device on the front surface or the back surface or both front and back surfaces, if necessary, or by dipping, or by pressurization or depressurization. The resin impregnation treatment can be performed by forcibly impregnating the entire surface plate with the synthetic resin. Since the resin impregnated surface plate becomes dense and hard, the strength is increased and the adhesive force with the composite plate or the decorative sheet is improved.

The surface plate is laminated and adhered to the surface of the composite plate through an optional adhesive and subjected to heat-pressing according to a conventional method to obtain the laminated plate of the present invention. In addition, the laminated plate of the present invention can be obtained by laminating the individual plates constituting the composite plate via an optional adhesive, further laminating the surface plate, and hot-pressing according to a conventional method.

In the laminated board of the present invention, a wood fiber board or wood shavings board obtained from a softwood material is used as a surface material. These materials have a material color close to white or pale yellow and have excellent surface smoothness. Therefore, it is suitable for use as a surface material or a decorative material in the interior and furniture of buildings.

Further, a decorative sheet is laminated and adhered to the surface of the face plate, if necessary. For laminating and bonding the decorative sheets, an arbitrary adhesive such as a thermoplastic adhesive, a thermosetting adhesive, or a room temperature curable adhesive is used. According to.

As the decorative sheet, a veneer, an artificial veneer, a decorative paper, a decorative cloth, a decorative synthetic resin sheet or the like is used. The decorative sheet may be laminated and adhered to the surface plate by using a pre-coated top sheet, or the decorative sheet may be laminated and adhered to the surface plate and then coated, such as top coat.

As described above, the wood fiber board or wood shaving board obtained from the softwood used as the surface material has no unevenness in the material color and the surface smoothness is good, so a thin decorative sheet is attached. Even so, the defects on the surface of the laminated plate do not appear through the decorative sheet.

Furthermore, since these surface materials have a white or pale yellow color, it is possible to positively develop this bright color through a thin decorative sheet and contribute to the improvement of the design. In this case, a transparent or translucent adhesive or an adhesive which becomes transparent or translucent by curing is preferably used for laminating and bonding the decorative sheets.

Further, the adhesive may be optionally colored if necessary. By using a colored adhesive, it is possible to express different colors even with the same decorative sheet, and to change the design. The adhesive used in this case may be opaque.

【Example】

 FIG. 1 shows the construction of a laminated board according to an embodiment of the present invention, in which four laminated veneer boards are attached so that their fiber directions are orthogonal to each other, and the laminated board is used as a composite board 1. A surface plate 2, which is a wood fiber board or wood shavings board obtained from a softwood, is laminated and adhered on the surface thereof, and a decorative sheet 3 is further laminated and adhered on the surface thereof.

[0022]

[Effect of the device]

 The laminated board according to the present invention uses a wood fiber board or a wood shaving board obtained from a softwood as a surface board, which is a homogeneous industrial product and has a smooth surface and has a bright white or pale yellow color. It is preferably used as a surface material or a decorative material in the interior of buildings and furniture.

In addition, even when the decorative sheet is laminated and adhered to the surface plate, a defect or surface color unevenness of the surface plate does not appear through the decorative sheet, and a thin decorative sheet can be used. The cost can be reduced. Furthermore, since the material color is bright, it is possible to improve the design by positively revealing it through a thin decorative sheet.

The wood fiber board or wood shaving board used as the surface board can be obtained by defibrating and cutting defective wood or waste wood, and is extremely significant in terms of effective use of resources. is there.
