Description

Detailed Description of the Invention (Field of Industrial Application) The present invention has a decorative surface made of natural wood veneer, and the decorative surface is interposed with a thermoplastic resin film containing fine cellulose aggregate. This relates to a metal plate-clad decorative panel that does not crack or peel off.

(Prior art) Recently, metal panels with decorative surfaces have been widely used as a substitute for expensive wood for walls, furniture, etc., and because they are suitable for mass production, but conventional panels use PVC film for the decorative surfaces.
Some were printed or molded to have the grain of natural wood.

(Problem to be solved by the invention) However, since the decorative surface of the metal panel described above is made of PVC film, even if it is made of natural wood veneer,
Not only is there a difference in appearance, but the feel when touching the surface is completely different from that of a natural wood veneer.Also, the decorative film expands and contracts with long-term use, and the adhesion between the metal plate and the PVC film is difficult. Because it is unreasonable, it is easily peeled off or torn due to changes in dryness, humidity, and temperature, and because the expansion and contraction ratio is different from that of the metal plate, there have been problems such as partial peeling, swelling, or tearing.

(Means for Solving the Problems) The present invention has been proposed to solve the above problems.
One side 1 of a thermoplastic resin film l with a thickness of 1 to 0.81
A veneer 2 with a thickness of 0.1 to 0.3 is placed on the other side 1b
A decorative panel A configured such that a decorative sheet B, which is made by polymerizing and adhering a reinforcing fabric 3 such as paper or cloth, is pasted onto a metal plate 4 with the reinforcing fabric 3 surface of the decorative sheet B as an adhesive surface. It is.

(Function) The decorative panel A constructed in this way has a film-like veneer board 2 made of natural wood and a metal plate 4 bonded together via a thermoplastic synthetic resin film 1 containing fine cellulose aggregate. Furthermore, since the film 1 and the metal plate 4 are bonded together through a reinforcing fabric 3 such as paper or cloth, the bond is reliable and will not peel off.

In addition, the decorative surface is a natural wood veneer 2, so that the furniture made of this looks like it is made of natural wood itself, and the underlying film 1 also contains fine aggregate as mentioned above. Because of this, it has hygroscopic properties, and the decorative sheet B
Because it has a moderate amount of moisture absorption, it has a feel similar to that of thick veneer.

In addition, since the thermoplastic synthetic resin film 1 containing fine aggregate has good moldability, it fits well when press-molded together with the metal plate 3 (furthermore, the film 1 and reinforcing fabric 3. The reinforcing fabric 3 and the metal plate 4 have good adhesion to each other, so the reinforcing fabric 3
The film L and the metal plate 4 bonded together through the
Due to the expansion/contraction and reinforcing action of the veneer, the veneer 2 glued to the surface of the veneer may come off at some corners.

It will never break.

(Example) Figure 1 shows a typical example of the present invention, in which 1 uses wood flour as a cellulose-based fine aggregate, and 5 to 30
A soft or hard film of vinyl chloride containing 0.1% to 0.8% of sodium chloride, with a thickness within the range of 0.1 to 0.8%,
2 indicates a veneer, and veneer 2 is natural wood with a rating of 0.1 to 0.3
One side la of the film 1 is sanded using a sheet-like sheet with a thickness of mm to make it rough, and the fine aggregate contained in the surface is exposed on the side 1a. A veneer 2 is adhered to 1a with an adhesive, and paper, cloth, or a reinforcing fabric 3 made of paper and cloth is polymerized and adhered to the other side 1b to form a decorative sheet B.
is attached to a metal plate 4 made of iron, steel, aluminum, etc. using the 3 sides of the reinforcing fabric as an adhesive surface.In this embodiment, the metal plate 4 is
The metal plate 4 is molded and the decorative sheet B is pasted thereon with hot melt, but there are also cases where the decorative sheet B is pasted onto the metal plate 4 and then press-molded.

In addition, when adhering the veneer 2 to the film 1, the surface 1 of the film 1 is
In some cases, the veneer 2 is bonded without being sanded, but it is sanded to make the bond stronger.

In addition, the reinforcing fabric 3 is fabric, paper, or both fabric and paper pressure-fused to the other surface 1b of the film 1, and in this case, the reinforcing material is applied to the surface of the film 1 that is roll-formed and sent out by the roll. While pulling out the fabric 3, the fabric 3 is overlapped with the film 1 and pressed and fused using a thermocompression roll, and the metal plate 4 is bonded thereon, and the reinforced fabric is also attached at the bent corners as shown in Figure 3. expands, reinforcing the decorative sheet B and at the same time improving adhesion to the metal plate 4.

(Effects) The decorative panel according to the present invention has a 0.1 to 0.3 layer thickness on one side of a 0.1 to 0.8 m-thick thermoplastic resin film containing cellulose-based fine powder aggregate. A decorative sheet consisting of a veneer board and a reinforcing fabric such as paper or cloth polymerized and bonded to the other side is pasted onto a metal plate with the reinforcing fabric side of the decorative sheet as the adhesive surface, so this is used. Furniture, walls, etc. made of wood have a similar appearance to those made of natural wood, and the metal plates make them sturdy.

In addition, the decorative veneer is bonded with a resin film containing fine cellulose-based aggregate as the lower layer, so even if the natural wood veneer is extremely thin, the decorative sheet as a whole has an appropriate amount of moisture absorption. The veneer has a feel similar to that of a wood veneer with a normal thickness.6 In addition, the veneer is bonded to a synthetic resin film containing fine powder aggregate, and a reinforcing fabric is further bonded to the film, and the metal plate is bonded to the reinforcing fabric surface. Since the metal plate and the veneer are adhered to each other, the adhesion between the metal plate and the veneer is effectively performed, and by making the expansion and contraction of the metal plate close to that of the decorative sheet, the veneer does not peel off due to changes in humidity and temperature.

Furthermore, the thermoplastic resin film containing fine aggregate has little expansion and contraction, and has good moldability and shape retention, and even if it is molded integrally with the metal plate using a press, the veneer is in the form of an extremely thin film, so it can be used in some corners. It does not tear even when bent, etc., and has good adhesion, so it can be formed with a uniform thickness, and unlike conventional metal panels, the decorative film does not stretch and become thinner at some corners, and the surface It is a film-like veneer of natural wood, and it is firmly bonded to the underlying metal plate, so it will not stretch and bulge or shrink and crack even after a long period of time. .
