DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden board having a decorative surface suitable for use in house furniture, light weight, and having a required thickness and a required mounting strength. The present invention relates to providing a composite material.

[0002]

2. Description of the Related Art As a constituent material of various types of household furniture such as a shoe box, a storage unit, a vanity table, etc., it has excellent surface cosmetic properties.
There is a need for a woody, plate-like composite material having a predetermined strength and a lightweight, having a bending strength and a wood screw holding force.

[0003] When a particle board, a medium fiber board, or the like is used as a constituent material for such house furniture, this kind of house furniture is heavy, and in a particle board, this kind of house furniture is used. In addition, there is a problem that the surface cosmetic properties and the woodcut cosmetic properties required by the above are inferior, and in the case of the medium fiberboard, the plastic deformation accompanying the continuous load is large, and it is not suitable for this kind of material for living furniture. .

[0004] From such a point, as shown in FIGS. 21 and 22, a frame 101 'is formed by using a frame 101 to form a rectangular plane, and plywood or the like is provided on both sides of the frame 101'. Attempts have been made to construct house furniture using a flash panel-shaped plate member 100 in which a surface plate member 102 is attached.

[0005] As described above, the plate-shaped material 100 constituted by sticking the surface plate 102 such as plywood on both surfaces of the frame 101 'is provided.
Has a convenient thickness as a constituent material of this kind of house furniture, and has the advantage of being a lightweight constituent material, but on the other hand, this configured plate-like material 100 has a frame 101 ′ structure. Therefore, there is a problem that the degree of freedom in designing the arrangement of the members is small, and that an extra step for configuring the frame 101 'is required.

Further, in the plate member 100 having such a configuration, it is difficult for the plate surface constituted by the surface plate member 102 to have flatness, and the surface plate member 1 such as a laminated plywood is not provided.
02 tends to have a dent-like difference in the surface of the
In addition to the problem that the component frame material 1 ′ is likely to be warped or twisted, the space between the frame members 101 ′ is a space,
There was a problem that the luxury sound was impaired, for example, the beating sound became a characteristic hollow sound.

[0007] As a solution to the problem of the flash panel-like plate-like material, a wide core plate is prepared by arranging small pieces of rawan and softwood with or without bonding their end faces. There is a lumbar core plywood with two ply lauan veneers on each side. This lumbar core plywood has the feature that the degree of freedom in the design of the members is flexible and that the tapping sound is a solid sound similar to that of a muk material or the like.

[0008]

However, this type of lumbar core plywood has a flexural strength as a material for living furniture, since the surface plate to be stuck on both sides of the core plate is a 2-ply lauan veneer. In addition, there is a problem that the deformation of the bonded surface of the bonded core plate affects the surface material and impairs the cosmetic property.

A lumber core plywood having a core plate of this kind of lauan wood and softwood split wood is prepared as a material having a sufficient thickness suitable for a constituent material of living furniture. It becomes too heavy as a component of furniture for housing,
As a result, in the case of using a lumbar core plywood of this type for the construction of house furniture, the mounting portion of the house furniture has a corresponding mounting strength, for example, the provision of a special reinforcing wall base material for mounting the house furniture. There are many restrictions on the assembly and configuration, such as the necessity to configure hinges and the like in the constructed house furniture as having sufficient strength, for example. There was a defect.

[0010] On the other hand, it is required that a component of this kind of living furniture be provided with a predetermined surface decoration on the living furniture constituted by using this constituent material.

[0011] However, the surface treatment of sticking decorative paper on the surface of the lumbar core plywood and applying a topcoat to the lambar core plywood involves handling heavy and thick lumbar core plywood in each work process. In addition, there is a problem that the workability of each operation is difficult, and furthermore, a damaged product due to the surface makeup treatment is easily generated.

[0012] Such surface treatment is generally performed by using a lined decorative paper sticking device and a similarly lined coating device to paste decorative paper and to apply a top coat on the stuck decorative paper. To be applied.

[0013] It is extremely difficult to apply the above-mentioned surface decoration to lumbar core plywood using such a device for the following reasons. Therefore, even if it was desired to use lumbar core plywood as a material for living furniture, the cost problem could not be solved.

In the process of sticking decorative paper to the lumbar core plywood and the finish coating process, it is heavy.
Moreover, since the bulky lumbar core plywood is moved one by one in each of the decorative paper pasting devices and the topcoating device, and since it is necessary to reverse this,
A high-performance drive system is required for the decorative paper pasting device and the topcoating device on the lumbar core plywood, and furthermore, the work involved in this is a problem of heavy labor.

Further, since the lumbar core plywood moved in each device is heavy and bulky, means for accurately moving and stopping the lumbar core plywood on each device are separately provided. In addition, it is necessary to keep the feeding speed of the lumbar core plywood in each device within a predetermined speed so that the lumbar core plywood does not shift during the process of attaching the decorative paper and applying the topcoat.

Further, in the process of attaching decorative paper to the lumbar core plywood and the process of top coating,
Curing is required for the application of the decorative paper and the coating process of the top coat, and there is a problem that the bulky lumbar core plywood requires a space for each curing.

Further, in the process of sticking the decorative paper to each side of the heavy and bulky lumbar core plywood and coating the top coat, the paste of the decorative paper and the coating of the top coat are applied. During processing, the decorative paper provided on the other plate surface on the line side, or the overcoated surface is likely to be scratched, and there is a problem that the cosmetic property of the lumbar core plywood constituted is impaired, Product yield in the production of lumbar core plywood is likely to be difficult, and in the above-described process of attaching decorative paper to each surface of the lumbar core plywood, and applying the top coat, a protective film is attached to the other surface one by one. However, there is a problem that the product cost is increased when the curing treatment is performed.

The present invention has bending strength and mounting properties suitable for the construction of living furniture, has a required plate thickness and surface decorativeness, is lightweight, and has a high degree of design freedom in the connection of members. One of the main objects of the present invention is to provide a plate-shaped composite material having a flat surface and to provide a plate-shaped composite material which can be easily manufactured.

Since the surface plate made of plywood with more than the number of plies is bonded and integrated, it has bending strength and wood screw holding force suitable for materials for home furniture, and moreover, the degree of freedom in the design of the connection of members There is an advantage that the flatness is brought to the constructed plate surface, and the tapping sound is a solid sound similar to a muk material and the like, and it is a plate-like composite material suitable for high-quality residential furniture. ing.

Further, the plate-like composite material configured as described above has a sufficient thickness suitable for the constituent material of the household furniture, and further, does not require excessive mounting strength at the mounting portion of the household furniture. In addition, there is an advantage that a lightweight plate-like composite material that does not cause an excessive load on a hinge portion or the like of the constructed house furniture.

Further, in the plate-like composite material according to the above configuration, a sheet / film-like surface material is attached to one or both surfaces of one of the surface plates provided on the plate-like core material,
An overcoat is applied on the pasted sheet / film surface material. Then, since the decorative surface plate is configured such that the surface opposite to the side on which the top coat is applied is integrally bonded to the plate-shaped core material, the sheet-film-like surface material is added to the plate-shaped composite material. And the step of applying a top coat on the sheet / film-like surface material can be performed on a lightweight, non-bulk surface plate. There is an advantage that the material can be applied and the top coat can be performed by a relatively small device and the labor can be reduced.

[0127] The plate-like composite material thus constituted is composed of a sheet / film-like surface material provided in the plate-like composite material.
Since the overcoated film provided on the pasted sheet / film-like surface material can be provided by pasting and painting on a lightweight, thin-walled surface plate before being integrally bonded to the plate-shaped core material, this sheet -During the work of sticking the film-like surface material and the finish coating work, it is possible to easily move and stop the surface plate accurately in the manufacturing equipment.
During the work of attaching the sheet / film-like surface material and the work of overcoating, there is an advantage that the surface plate in the apparatus can be moved at a relatively high speed without causing displacement.

[0128] The plate-like composite material thus constituted is composed of a sheet / film-like surface material provided in the plate-like composite material.
Since the top coating film provided on the pasted sheet / film surface material can be provided by pasting and painting on the surface plate before being integrally bonded to the plate core material, the sheet / film surface material can be provided. This has the advantage that curing can be achieved in a relatively narrow space due to the attachment of the film and the overcoating on the sheet / film-like surface material.

[0129] The plate-like composite material thus constituted is obtained by attaching a sheet / film-like surface material to a light-weight and thin-walled surface plate before being integrally bonded to the plate-like core material.
The decorative surface plate can be constituted by top coating on the film-like surface material, and both surfaces of the plate-like core material are overlaid with the uncoated surface of the decorative surface plate via an adhesive. Because it can be constituted by pressing a large number of sets in a stacked state, in producing this plate-like composite material, it does not cause scratches on the sheet / film-like surface material, the top coat film surface, and does not impair its cosmeticity Has advantages.
