ている。2. Description of the Related Art Decorative boards and decorative panels are widely used for housing equipment, furniture, etc. because of their excellent design and easy provision of weather resistance, heat resistance, abrasion resistance and stain resistance. As the design of housing equipment and furniture has become more sophisticated, more and more cases use curved surfaces, and along with this, the decorative boards and decorative panels are often bent.

なかった。As an example of these bending methods, there are so-called combing method and V-cutting method, and a bending method of a composite decorative board or the like in which a vinyl chloride decorative film is attached to a wooden board is a cabinet of light electric equipment. Is often used in. However, these processing methods are used only for a composite plate to which an extremely thin decorative film is attached, and have not been applied to a composite plate to which a thick decorative plate is attached.

性に問題があった。As another example, a substrate (for example, lauan plywood) is previously bent by an NC router or the like,
A post-form processing method is used in which a high-pressure melamine plate that is heat-softened is attached via an adhesive. In this case, there is a problem in productivity because the production speed of the NC router processing of the substrate is slow.

げ加工ができないという問題があった。On the other hand, an artificial marble having a thickness of about 6 to 15 mm is also softened by heat and bent.
However, the artificial marble having a thickness of 6 mm or more is expensive, heavy and difficult to handle, and there is a problem that it cannot be finely bent because a radius of curvature of 40 mm or more is required even if it is bent.

径が大きくなるので好ましくない。The surface plate material 2 used in the present invention has a thickness of 1 to
It is in the range of 4 mm, and can be bent under heating (including thermoplastic resin and thermosetting resin as long as it has the property of softening and bending by heating).
There is no particular limitation as long as it is used, but because it is used as a surface layer, not only the design but also wear resistance, impact resistance,
Those having excellent physical strength such as heat resistance are preferable, and examples thereof include acrylic artificial marble (preferably having a heat softening property and a softening temperature of 100 ° C. or higher) and a plastic plate such as a polycarbonate plate. Among these,
Acrylic artificial marble is particularly preferable because it is excellent in design and has a high-class feeling. When the thickness is less than 1 mm, bending workability is improved, but designability and physical strength are disadvantageous, and when the thickness exceeds 4 mm, bending workability is deteriorated and the radius of curvature is particularly large, which is not preferable.

がある。The plate-like base material 3 usually has a thickness of 5 to 5.
Examples include 30 mm lauan plywood, wood boards such as MDF (medium density wood fiber board) and particle boards, and other base materials. In the present invention, a composite plate 1 obtained by laminating the above-mentioned surface layer plate material 2 and plate-like base material 3 by a conventional method is used. This composite plate 1 has the advantages of not only excellent design, but also light weight, high physical strength, and low cost.

ましい。In bending the composite plate 1, first, the shape of the grooves 31 and the number of the grooves 31 corresponding to a desired radius of curvature are calculated, and a predetermined number of the plate-like base material 3 on the back surface of the composite plate 1 is calculated. The groove 31 is formed at a place using a saw machine or the like. Therefore, the shape and the number of the grooves 31, and the groove 3 in the case of a plurality of grooves 31
The interval between 1 may be appropriately selected. The shape of the groove 31 may be V-shaped, U-shaped, semi-circular, or the like.
If the angle is calculated from the angle of the curved surface and the number of grooves and the groove 31 is formed at an appropriate angle, bending can be performed without forming a gap in the curved surface portion, and the strength is not reduced, which is more preferable. Also,
The depth of the groove 31 is preferably such that it reaches the surface layer plate material 2.

Is heated until it softens, and bending stress is applied to the plate-shaped substrate 3 with the plate-shaped substrate 3 inside so as to form a curved surface to a desired angle, followed by cooling and fixing. Heating is usually the surface layer plate 2
Although it is performed from the side, it is preferable to slightly heat the plate-shaped substrate 3 side as well because a thermal gradient is less likely to occur and uniform heating can be performed.
The heating temperature varies depending on the type of material, the amount of the filler added, and the degree of crosslinking, but it is preferable that the curved surface portion is not whitened or cracked. Examples of the heating means include far infrared rays, hot air, high frequency waves, etc., which can be selected depending on the material and can be used in combination.

１’が得られる。The groove 31 formed in the plate-shaped substrate 3 is filled with the adhesive or the filler 4 before or after the bending process.
As the adhesive or the filler 4, a rubber adhesive, a hot melt adhesive, an epoxy adhesive, a urethane adhesive,
Examples include various adhesives such as acrylic adhesives and fillers such as foaming urethane resin. Among these, it is particularly preferable to use a rubber-based adhesive or a hot-melt adhesive having a strong initial adhesive force, and when injected into the groove 31 before bending, the adhesive 4 is softened and the solvent is removed during heating. Especially effective. The timing of injecting the adhesive or the filler 4 into the groove 31 is preferably before bending when using the adhesive. Further, in the case of a structure in which a void is generated due to the groove 31 after bending, it is preferable to use a filler from the viewpoint of eliminating the void and strength. The period of use is preferably after bending, but there is no particular limitation because some have both the effect of an adhesive and the effect of a filler. In this way, the curved panel 1'of the present invention is obtained.
