As another conventional example, the thickness is 0.5 mm.
There is known a method of manufacturing the thick sheet described above by a batch press. This thick sheet has, for example, a transparent resin layer such as acrylic or PET on the surface side, a colored resin layer such as ABS or PVC on the base side, and a pattern printing layer disposed between them. These multiple layers are batch-pressed one by one.

However, the method of batch-pressing this thick sheet has a thickness of 0.5 mm or more, which increases the cost of the decorative sheet and deteriorates the productivity.
Furthermore, since the decorative sheet is thick, it is difficult to wind the edge of the decorative sheet around the substrate, and the appearance of the edge of the decorative sheet is poor. In addition, when a thin sheet is used, there is a problem that tension is not applied at the time of pressing, so that wrinkles may occur and the finish may not be neat.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below based on the embodiments shown in the accompanying drawings.

The decorative panel 3 of this embodiment is constructed by laminating and integrating the decorative sheet 2 on the substrate 1 while applying tension to the decorative sheet 2 by the roll laminator 10 shown in FIG.

The substrate 1 is made of fiber reinforced plastic and is press molded with a sheet mold compound (SMC) material. The size of the substrate 1 is, in the example shown in FIG.
The vertical width D is 2050 mm, the horizontal width L is 800 mm, and the total thickness M is about 20 mm, but of course, it is not limited to this size. Further, the material of the substrate 1 is not limited to the fiber reinforced plastic, but the use of the fiber reinforced plastic has an advantage that it can withstand the use around water such as a wall panel of a bathroom. In addition, FIG.
As shown in (c), ribs 8 are provided around the entire circumference of the substrate 1, and the ribs 8 reinforce the thin plate-shaped substrate 1 to increase the strength of the decorative panel 3 as a whole. Have secured. Further, the hollow space of the substrate 1 is filled with urethane heat insulating material 16. Urethane insulation 16
Thus, the weight of the substrate 1 and the heat insulating property are improved.
Note that reference numeral 13 in FIGS. 3B and 3C is a backup material.

As shown in FIG. 1, the decorative sheet 2 is made of PP.
Alternatively, it is a three-layer composite sheet including an opaque underlayer 4 made of PET, a transparent surface layer 5 made of PET, and a printing layer 6 provided therebetween. The base layer 4 and the surface layer 5 are made of a combination of PP / PET or PET / PET.
It will be one of the combination of. The underlayer 4 has a thickness a of 50 to 100 μm. When the underlayer 4 is thinner than 50 μm, the pattern of the substrate 1 appears in the printed layer 6 and the hiding property is deteriorated, and when it is thicker than 100 μm, large wrinkles occur due to heat shrinkage during lamination. In other words, the influence of shrinkage due to heat at the time of coating the adhesive 7 by the coating header becomes large, and mirror surface smoothness after lamination cannot be obtained. Therefore, by setting the thickness a of the underlayer 4 to 100 μm or less, the influence of shrinkage due to heat at the time of coating the adhesive 7 is reduced, and streaks (wrinkles) are less likely to occur in the flow direction. When the underlayer 4 is made of PP, it is difficult to manufacture a PP thinner than 50 μm, and a PP thicker than 100 μm is difficult to manufacture.
Due to the shrinkage due to heat at the time of applying the adhesive 7, streaks in the flow direction become noticeable after lamination. As a result, in order to improve the mirror surface smoothness after lamination, the thickness a of the underlayer 4 is set within the range of 50 to 100 μm.
When the underlayer 4 is made of PET, by setting the thickness a as described above, the heat shrinkage becomes smaller and the finished mirror surface smoothness becomes even better.

On the other hand, since the surface layer 5 is made of PET, it has excellent transparency. Compared with other transparent resins (for example, acrylic, PP, PE, PVC, etc.), this PET is also excellent in scratch resistance and solvent resistance, and is also excellent in environmental aspects. Here, the thickness b of the surface layer 5 is 50 to 200.
μm. If the thickness is less than 50 μm, a deep feeling cannot be obtained visually, and if the thickness is more than 200 μm, the end portion 2a of the decorative sheet 2 has a poor winding property. Therefore, 50 to 200
When the thickness is set to μm, the hardness is such that a deep feeling can be obtained and the end portion 2a of the decorative sheet 2 can be easily rolled into the substrate 1.

The back surface of the decorative sheet 2 (the surface on the substrate 1 side)
1 is coated with a hot melt adhesive 7 (PUR) with a predetermined thickness using the coating header 14 shown in FIG. By applying the adhesive 7 to the decorative sheet 2 side in this way, it becomes possible to perform a uniform coating, as compared with the case where the adhesive 7 is applied to the substrate 1 where the surface is apt to be uneven. Also,
If a solventless hot melt type is used as the adhesive 7,
The problem of swelling due to foaming of the adhesive 7 after lamination does not occur. Here, in order to obtain a highly durable decorative panel 3, it is desirable to use a reactive urethane hot melt (PUR). If the substrate 1 is a breathable material such as wood, a solvent-based or emulsion-based adhesive can be used as the adhesive 7, but in the case of fiber-reinforced plastic as in this example. Is air-impermeable, so that it is possible to enhance the finish of mirror surface smoothness by using a hot-melt adhesive that does not cause post-foaming.

Next, the laminating apparatus 17 conveys the substrate 1 preheated to about 50 ° C. in the preheating zone 15 by the belt roll 9a as shown in FIG. On the other hand, on the back surface (surface on the side of the substrate 1) of the base layer 4 of the decorative sheet 2 supplied from the supply roll 30, by using the coating header 14 shown in FIG. 1, such as a hot melt adhesive (PUR). After applying the adhesive 7 with a predetermined thickness, the adhesive 7 is supplied onto the substrate 1 and the decorative sheet 2 is bonded onto the substrate 1 while applying tension to the decorative sheet 2 by the roll laminator 10.

Then, the base layer 4 of the decorative sheet 2 is set to 50
By using PP or PET having a thickness of up to 100 μm, the concealing property of the substrate 1 can be improved, the pattern of the substrate 1 can be prevented from appearing, and the effect of shrinkage due to heat during lamination can be reduced. As a result, it becomes difficult for streaks to form in the flow direction, and the mirror surface smoothness after lamination can be improved. Further, the surface layer 5 is 50 to 20
By forming the PET with a thickness of 0 μm, a deep feeling is visually generated, and the decorative sheet 2 can be made thin.
The end portion 2a of the sheet is well wound, and a good finish can be obtained. In addition, the decorative panel 3 is formed by the sheet stacking method.
Therefore, the productivity is significantly improved as compared with the conventional overcoating of coating and batch press. In addition, since the roll laminator 10 can apply tension to the decorative sheet 2, wrinkles are less likely to occur even if it is thin,
The mirror surface smoothness after finishing can be further enhanced.

Further, in this example, since the belt roll 9a in which the endless belt 21 is wound between the pair of front and rear drive pulleys 20, 20 is used as the conveying device 9, the pressure from the roll laminator 10 is applied. It can be absorbed by the endless belt 21 having a cushioning property, and the substrate 1 is less susceptible to pressure. Therefore, the pressure during lamination can be made uniform and the finish can be improved. By the way, in a normal feed roll, since there is a difference in pressure between the part with the roll and the part without the roll, the influence of the pressure is exerted particularly on the substrate 1 filled with a heat insulating material such as soft urethane or other foam material. It is difficult to improve the finish. Therefore, by adopting the belt roll method as in this example, the finished mirror surface smoothness can be improved.

Further, the roll laminator 10 for applying tension to the decorative sheet 2 of this example is constituted by disposing one cold pressure rubber roll 12 behind one hot pressure rubber roll 11. The numbers of the hot-press rubber rolls 11 and the cold-pressure rubber rolls 12 may be plural. In this way, the adhesive 7 can be flowed to obtain smoothness in a state where the fluidity of the adhesive 7 is maintained by first passing it through the hot pressure rubber roll 11, and then by passing it through the cold pressure rubber roll 12, There is an advantage that it can be cooled and fixed while maintaining its smooth surface.

Here, the rubber hardness of the rubber rolls 11 and 12 is preferably set in the range of 30 ° to 70 °. The reason is that if the rubber hardness is less than 30 °, the rubber is too soft to pull the adhesive 7 smoothly, and if it exceeds 70 °, it is too hard and the contact pressure distribution between the decorative sheet 2 and the substrate 1 is too large. Is large, and it becomes impossible to deal with unevenness of the substrate 1, resulting in poor finish. That is, by setting the rubber hardness in the range of 30 ° to 70 °, it is possible to deal with the unevenness of the substrate 1 and to level the adhesive 7. In this example, the rubber hardness of the hot pressure rubber roll 11 is 50 ° and the temperature is 60 ° C., and the rubber hardness of the cold pressure rubber roll 12 is 50 ° and the temperature is 20 ° C.
Of course, this is an example and the present invention is not limited to these numerical values.

Further, as shown in FIGS. 3 and 4, the substrate 1
A plurality of pairs of winding rolls 18 on the left and right sides of the winding roll 18 are arranged along the flow direction.
8, the end portion 2a of the decorative sheet 2 is wound around both end surfaces of the substrate 1. The winding roll 18 is, for example, a rubber roll having a hardness of 50 °, and is shown in FIGS.
As shown in FIG. 2, the end portion 2a of the decorative sheet 2 can be wound along the end surface of the substrate 1 by inclining the rotary shaft 18a of the winding roll 18 from horizontal to vertical. Further, in this example, the winding roll 18 is composed of a water-cooled roll, and when the decorative sheet 2 is wound, the hot-melt adhesive 7 can be quickly cooled and solidified, and the repulsion of the decorative sheet 2 can be prevented. Planned.
