  However, in the technique described in Patent Document 1, an aluminum plate, a steel plate, or the like is used as a base panel, but it is not disclosed that the adhesive is heated by electromagnetic induction heating using the aluminum plate or the steel plate. On the other hand, in the technique described in Patent Document 2, since the hot melt resin tape is heated and melted by electromagnetic induction heating instead of the base panel, a hot melt resin tape having a property of melting by electromagnetic induction heating is prepared. It is necessary to use a general-purpose hot melt resin for bonding. In addition, since the electromagnetic induction heating head is pressed from the front surface of the tile, heat is hardly transmitted to the panel side, and there is a problem that reliable adhesion becomes difficult when the tile is thick.

  In addition, when manufacturing a cover panel other than a tile panel (for example, a decorative panel / decorative panel, etc.), in many cases, the cover material is bonded to the base panel using a two-component adhesive. The curing time until the adhesive is cured is long and the productivity is remarkably low. Therefore, a forced drying furnace or hot press is used to shorten the curing time. However, in the case of a hot press, the fire and heat cannot be dropped except in the case of a long holiday, which is not preferable from the viewpoint of energy saving. In the case of hot pressing, since a special structure is required, it is difficult to easily cope with changes in the production line.

  Hereinafter, the best mode for carrying out the present invention will be described in detail based on examples.

  First, Embodiment 1 of the present invention will be described with reference to FIGS. In this embodiment, the present invention is applied to the manufacture of tile panels. FIG. 1 is a diagram illustrating an overall configuration of a tile panel manufacturing system according to the present embodiment, and FIG. 2 is a flowchart illustrating an example of a tile panel manufacturing process according to the present embodiment. 3A and 3B are cross-sectional views of the main part of the present embodiment. FIG. 3A is a cross-sectional view of the base panel, and FIG. 3B is a cross-sectional view taken along line # A- # A in FIG. Sectional view (C) is a sectional view of FIG. 1 taken along line # B- # B and viewed in the direction of the arrow. As shown in FIG. 1, the tile panel manufacturing system 10 of the present embodiment includes an adhesive application device 20, a base panel heating device 30, a tile sticking device 40, and a drying device 50. The base panel 70 to which the tiles 74 are attached is sequentially transported from the adhesive application device 20 to the drying device 50 by the conveyor 16 on the table 14 supported by the feet 12. The drive mechanism of the conveyor 16 is well known.

  In the present embodiment, as the base panel 70, as shown in FIG. 3 (A), a panel in which metal plates 76A and 76B such as steel thin plates are provided on the front and back surfaces of a gypsum board 72 as a base material is prepared (FIG. 2). Step S10). The adhesive 26 is applied to the surface to be bonded of the base panel 70 (in the illustrated example, the metal plate 76A side) by the adhesive application device 20 (step S12). In the illustrated example, the adhesive application device 20 includes a pair of struts 22A and 22B that are opposed to each other with the table 14 interposed therebetween, and a coating roller 24 that is rotatably supported by the struts 22A and 22B. For example, the inside of the application roller 24 is filled with an adhesive, and a large number of adhesive supply holes (not shown) are provided on the surface of the application roller 24 so that the base panel 70 is attached to the application roller. The adhesive 26 is applied to the metal plate 76 </ b> A when passing through the adhesive application device 20 while being in contact with 24. As the adhesive 26, for example, a known hot melt adhesive is used. The base panel 70 to which the adhesive 26 is applied is sent to the base panel heating device 30.

  In this embodiment, since the base panel 70 has a structure having metal plates 76A and 76B on the front and back surfaces, the base panel heating is performed so that the metal plates 76A and 76B can be used effectively. The apparatus 30 is assumed to heat the base panel 70 by electromagnetic induction heating. As shown in FIG. 1, the base panel heating device 30 includes an electromagnetic induction heating head 32 having an induction coil therein, and the electromagnetic induction heating head 32 includes a base 14 and a base 14 as shown in FIG. It is arranged between the conveyors 16. The electromagnetic induction heating head 32 is connected to a power supply device 34 for supplying a high frequency current. When a current is passed through the induction coil, a strong magnetic field is generated. Therefore, in the case of this embodiment, the metal plate 76B generates an eddy current by electromagnetic induction and a metal due to resistance. Generates heat. This principle is known as electromagnetic induction heating.

  When electromagnetic induction heating is performed from the lower metal plate 76B side, the metal plate 76B is mainly heated, the heat is turned upward, and as a whole, the adhesive 26 applied to the surface metal plate 76A side is heated. can do. If electromagnetic induction heating is performed from the surface metal plate 76A side, the heat rises upward, and the whole is not warmed. Moreover, since only the upper metal plate 76A is heated and expands, the base panel 70 is warped. On the other hand, in the present embodiment, the heat can be uniformly applied to the whole by applying heat from the lower side, thereby preventing the base panel 70 from warping (step S14). The preheated base panel 70 is sent to the tile sticking device 40 by the conveyor 16.

  In the tile sticking device 40, for example, the tile 74 is stuck to the surface of the base panel 70 to which the adhesive 26 is applied by the robot arms 42A and 42B (step S16). Here, the tile 74 is pasted using the robot arms 42A and 42B. However, various other known mechanisms may be used, or the pasting may be performed manually. . Next, the base panel 70 to which the tiles 74 are attached is sent to the drying device 50 by the conveyor 16.

  In the present embodiment, the drying apparatus 50 also performs drying by performing electromagnetic induction heating (step S18). As shown in FIG. 3C, the base panel 70 is made of metal by the electromagnetic induction heating heads 52A and 56A that heat from the upper side of the base panel 70 and the electromagnetic induction heating heads 52B and 56B that heat from the lower side of the base panel 70. Heating is performed from the front and back through the plates 76A and 76B. The electromagnetic induction heating heads 52A and 56A are connected to the power supply device 54 and are connected to the electromagnetic induction heating heads 52B and 56B. Conventionally, after attaching a tile using a hot melt adhesive, it was performed using a hot air furnace, but as in this example, drying is performed in a short time by performing electromagnetic induction heating from above and below. At the same time, warpage can be eliminated. The tile panel 60 obtained through the above steps is stored in a factory or the like until shipment, and shipped at a stage where it is used in the field, and is used as, for example, a building material for walls. As described above, since the tile panel 60 is prepared in a factory or the like and only the attachment to the wall surface or the like is performed on the site, the construction can be simplified.

As described above, according to the first embodiment, the tile panel manufacturing system 10 includes the adhesive application device 20, the base panel heating device 30, the tile sticking device 40, and the drying device 50. And
(1) The base panel 70 has a configuration in which the front and back surfaces of the gypsum board 72 are covered with metal plates 76A and 76B, and the base panel heating device 30 is a metal of the base panel 70 on the side where the adhesive 26 is not applied. Since the plate 76B is heated by the electromagnetic induction heating head 32, the heat is turned upward to warm the whole. For this reason, the adhesive 26 is preheated uniformly, and a tile can be reliably affixed. In addition, since the entire base panel 70 is heated, warping and distortion do not occur.
(2) Since the drying device 50 is also heated and dried by electromagnetic induction heating, it can be dried in a short time and can save energy as compared with a conventional drying method using a hot stove. . Moreover, since a special structure such as a conventional hot press is not adopted, it is possible to easily cope with a change in the production line.
(3) Since the base panel 70 is sequentially conveyed by the conveyor 16 from the adhesive application device 20 to the drying device 50, the manufacture of the tile panel 60 can be automated.
(4) If the tile panel 60 is prepared, it is only necessary to attach it to the wall surface at the site, so that the construction can be simplified.
(5) Compared to the case of using a conventional drying oven, the curing time can be shortened because the adhesive is cured on the production line. In addition, since electromagnetic induction heating is used, heating can be performed with little relation to the temperature difference, and productivity does not decrease even in midwinter. Furthermore, in the electromagnetic induction heating, it is sufficient to energize and heat only for a predetermined time, so that the panel can be produced with energy saving.

  Next, Embodiment 2 of the present invention will be described with reference to FIG. The present embodiment is an example in which the present invention is applied to the manufacture of tile panels as in the first embodiment, but is modified in terms of the timing and number of heating. FIG. 4 is a flowchart illustrating an example of a manufacturing process of a tile panel according to the second embodiment. First, a base panel is prepared (step S20), and adhesive coating is performed (step S22). Application of the adhesive 26 is performed, for example, with the same configuration as the adhesive application device 20 of the first embodiment. Next, in this embodiment, after the adhesive 26 is applied, the tile 74 is pasted first (step S24), and then the base panel 70 is heated (step S26). The same thing as the tile sticking apparatus 40 of Example 1 is used for sticking the tile 74. Further, the heating of the base panel 70 may be the same as that of the base panel heating device 30 of the first embodiment, but is not limited to this, and any heating using electromagnetic induction heating may be used. For example, the underlying panel 70 may be heated using superheated steam generated by electromagnetic induction heating (hereinafter, superheated steam generated by electromagnetic induction heating is referred to as “IH superheated steam”). For example, the heating is performed so that the adhesive 26 is about 40 ° C. and the metal plates 76A and 76B are about 70 ° C.

  Next, joint sanding is performed on the heated base panel (step S28), and then the base panel 70 is heated in two stages (steps S30 and S32). The heating here may also be one in which the metal plates 76A and 76B of the base panel are heated by electromagnetic induction using an electromagnetic induction heating head, or the above-described IH superheated steam may be used. Here, in the first heating (step S30), the adhesive 26 is heated to about 60 ° C., and the metal plates 76A and 76B are heated to about 100 ° C., and in the second heating (step S32), the adhesive 26 is heated. Heating is performed at about 90 ° C., the metal plates 76A and 76B at about 120 ° C., and the tile 74 at about 90 ° C. Such two-stage heating may be performed by providing two heating devices and sending the base panel 70 in order by the conveyor 16. By performing the two-stage heating, the heat diffusion is repeated and the base panel 70 is dried. When drying is completed, the joint sand is removed (step S34), and the completed tile panel 60 is awaiting shipment (step S36). The operations and effects of the present embodiment are basically the same as those of the first embodiment described above.

  Next, Embodiment 3 of the present invention will be described with reference to FIG. In the first and second embodiments described above, the tile panel is manufactured using the base panel 70 prepared in advance. However, the present embodiment is consistent from the manufacture of the base panel to the manufacture of the tile panel. This is an example of production. FIG. 5 is a flowchart illustrating an example of a manufacturing process of a tile panel according to the third embodiment. First, a base board serving as a base material for the base panel is prepared (step S40). As the base board, for example, a gypsum board 72 is used as in the first embodiment. Next, the adhesive 26 is applied to the front and back surfaces of the gypsum board 72 (step S42). The adhesive 26 may be applied in the same configuration as that of the adhesive applicator 20 of the first embodiment or may be configured differently. After application of the adhesive 26, the metal plates 76A and 76B are attached to the front and back of the gypsum board 72 (step S44). The metal plates 76A and 76B may be attached by an apparatus or manually. Steps S40 to S42 are frame work for the base panel.

  Next, the gypsum board 72 to which the metal plates 76A and 76B are attached is heated using electromagnetic induction heating (step S46). Heating with IH superheated steam may be used. The heating at this time is performed, for example, so that the adhesive 26 is about 50 ° C. and the metal plates 76A and 76B are about 90 ° C. Then, the base panel 70 is formed by pressing with a press apparatus (step S48). Next, after the base panel 70 is heated and preheated (step S50), the adhesive 26 is applied to the metal plate 76A (step S52), and the tile 74 is attached (step S54). Thereafter, joint sanding is performed (step S56), and two-stage heating is performed to dry the base panel 70 (steps S58 and S60). In the first stage heating (step S58), for example, the adhesive 26 is heated to about 60 ° C., the metal plates 76A and 76B are about 90 ° C., and the tile 74 is about 60 ° C. In step S60), the adhesive 26 is heated to about 90 ° C, the metal plates 76A and 76B to about 120 ° C, and the tile 74 to about 90 ° C. When drying is completed, joint sand is removed (step S62), and the tile panel 60 is awaiting shipment (step S64).

  In the above-described steps, the gypsum board 72 and the base panel 70 are bonded to the same conveyor 16 as in the first embodiment according to the order in which the above steps are performed, an adhesive application device, a metal plate pasting device, a pressing device, and a heating device. , Sent to the tile applicator and the dryer. The basic operations and effects of the present embodiment are the same as those of the first embodiment. However, according to the present embodiment, the tile panel 60 is efficiently manufactured because the base panel 70 is manufactured as part of the production. be able to. Further, since preheating at the time of manufacturing the base panel 70 can be utilized, energy can be effectively utilized.

  Next, Embodiment 4 of the present invention will be described with reference to FIG. In addition, the same code | symbol shall be used for the component which is the same as that of Example 1 mentioned above, or respond | corresponds. In the first embodiment, since the base panel 70 is configured such that the front and back surfaces of the gypsum board 72 are covered with the metal plates 76A and 76B, the base plate heating device 30 and the drying device 50 effectively use the metal plates 76A and 76B. Thus, although the electromagnetic induction heating is performed, the metal plates 76A and 76B are not necessarily configured to generate heat using the electromagnetic induction heating head, and the heating may be performed using superheated steam. Note that the IH superheated steam may be used as the superheated steam in this case. The tile panel manufacturing system 100 of the present embodiment includes an adhesive application device 20, a base panel heating device 110, a tile sticking device 120, and a drying device 130. The adhesive application device 20 is the same as that in the first embodiment. As shown in FIG. 6 (B), the base panel 140 of this embodiment has a laminated structure in which resin plates 144A and 144B are provided on the front and back of a gypsum board 142 as a base material, as shown in FIG. 6 (C). As described above, a base panel 140A made of only the resin board 146 may be used.

  The base panel heating device 110 of this embodiment uses a superheated steam supply device 111, and preheats by spraying superheated steam 112 from above the base panel 140 to which the adhesive 26 is applied. Unlike the first embodiment described above, the electromagnetic induction heating of the metal plate is not performed. Therefore, it is not necessary to perform the heating from the lower side of the base panel 140, but this does not prevent the heating from the lower side. Of course, you may make it heat from upper and lower sides. The preheated base panel 140 is sent to the tile sticking device 120. The tile sticking device 120 of this embodiment includes superheated steam supply devices 122A and 122B in addition to the robot arms 42A and 42B similar to those of the first embodiment described above. The tile 74 lifted by the robot arms 42A and 42B is heated by the superheated steam 112 supplied from the superheated steam supply devices 122A and 122B, and then pasted on the base panel 140. As described above, when the tile 74 side is also heated, the bonding to the adhesive 26 is favorably performed. The IH superheated steam can also be used as the superheated steam supplied by the superheated steam supply devices 122A and 122B.

  The base panel 140 to which the tile 74 is attached is sent to the drying device 130. In this embodiment, the superheated steam supply device 132 is used as the drying device 130, and the superheated steam 112 is sprayed onto the base panel 140 to dry the base panel 140. The IH superheated steam can also be used as the superheated steam supplied by the drying device 130. When the adhesive 26 is dried, the tile panel 150 is obtained. According to the present embodiment, since preheating and drying are performed using the superheated steam 112, it is possible to manufacture a tile panel regardless of the material of the base panel. Moreover, the point which can manufacture a tile panel in a short time, the point which does not warp a tile panel, the point which can be automated, and the point which only needs to attach to a wall surface on the spot are the same as Example 1 mentioned above. It is.

  Next, Embodiment 5 of the present invention will be described with reference to FIG. In Examples 1 to 4 described above, the present invention is applied to the manufacture of tile panels. However, the present invention is not limited to the manufacture of tile panels, such as decorative panels and decorative panels such as furniture, fittings, It can be applied to the manufacture of general laminated panels used as various building materials such as partitions, ceilings, and floors. FIG. 7 is a flowchart illustrating an example of the manufacturing process of the front panel according to the fifth embodiment. First, a base board serving as a base material for the base panel is prepared (step S80). Next, an adhesive is applied to the front and back surfaces of the base board (step S82). For the application of the adhesive, one having the same configuration as that of the adhesive application device 20 of the first embodiment may be used, or one having a different configuration may be used. After the adhesive 26 is applied, a surface material is pasted on the front and back of the base board (step S84). The attachment of the surface material may be performed by an apparatus or may be performed manually. Steps S80 to S84 are frame work for the base panel. Various known materials can be used as the base board and the surface material.

  Next, the base board to which the surface material is attached is heated with IH superheated steam (steps S86 and S88). Alternatively, when a metal plate is used as the surface material, the metal plate may be subjected to electromagnetic induction heating (IH heating) as in the first embodiment. The heating at this time is, for example, such that the adhesive becomes 100 ° C. or higher in the second stage heating. Then, by pressing with a press apparatus (step S90), a base panel is formed. The pressing is performed by, for example, a roll press, a standard press (around 3 seconds), pressure by cloth tension, or the like. Next, an adhesive is applied to the base panel (step S92), and a cover material is attached (step S94). The covering material here is, for example, wallpaper or a decorative board. Next, heating is performed in two stages with IH superheated steam, and heating and heat diffusion are repeated (steps S96 and S98). Here, similarly to steps S86 and S88, electromagnetic induction heating may be performed. Thereafter, by pressing (step S100), the facing material is bonded to the base panel to complete the laminated panel. The completed laminated panel is appropriately processed according to the application (step S102). The basic operation and effects of the present embodiment are the same as those of the third embodiment.

  Next, Embodiment 6 of the present invention will be described with reference to FIGS. Examples 1 to 5 described above have been described by taking the case of producing a panel-shaped laminated material as an example, but this example relates to a laminated material used as a heat insulating material for a liquefied natural gas pipe, for example. Is. FIG. 8A is a cross-sectional view showing a usage state of the laminated material of this embodiment, and FIG. 8B is an enlarged cross-sectional view showing the laminated structure. 9A to 9D are cross-sectional views showing the manufacturing process of the laminated material, and FIG. 10 is a cross-sectional view of the laminated material of this example. As shown in FIG. 8 (A), the laminated material 200 of this embodiment is used as a heat insulating material around the pipe 230 for liquefied natural gas. The pipe 230 is covered with foamed urethane 202, and the outer side thereof is covered with an aluminum sheet 204.

  The aluminum sheet 204 has a laminated structure as shown in FIG. 8B, and in the illustrated example, weather resistant resin layers 208 and 216 are provided on the front and back of the aluminum layer 212 by adhesives 210 and 214, respectively. It has a structure. The aluminum sheet 204 is bonded to the surface of the urethane foam 202 with an adhesive 206. In this embodiment, the present invention is applied when the aluminum sheet 204 is bonded to the urethane foam 202.

  With reference to FIGS. 9A to 9D, an example of a method for manufacturing the laminate 200 of this example will be described. First, as shown in FIG. 9A, the pipe 230 has substantially the same diameter. A core material 220 is prepared, and the periphery of the core material 220 is covered with foamed urethane 202A, 202B having a substantially semicircular cross section. The urethane foams 202A and 202B are not attached to the outer peripheral surface of the core material 220 for convenience of later removal of the core material 220, but the ends of the urethane foams 202A and 202B are bonded together with an adhesive 222. When the semi-circular urethane foams 202A and 202B are bonded with the adhesive 222, in principle, IH superheated steam is used to crimp the joint. When the bonding width is within 10 mm, bonding may be performed using both IH heating and IH superheated steam. Next, the aluminum sheet 204 coated with the adhesive 206 on the upper surface is conveyed to the core material 220 covered with the urethane foam 202 by a conveyor (not shown) or the like (see arrow FA). Until the aluminum sheet 204 approaches, the core material 220 stands by above the aluminum sheet 204 as shown in FIG. 9B. The application of the adhesive 206 is performed, for example, with the same configuration as the adhesive application device 20 shown in the first embodiment. In addition, after the application of the adhesive 206 or before the application, the aluminum sheet 204 is heated using electromagnetic induction heating. The heating at this time may be to heat the aluminum sheet directly by electromagnetic induction using an electromagnetic induction heating head, or to heat by heating superheated steam (IH superheated steam) generated by electromagnetic induction heating. May be.

  When the adhesive 206 is applied and the heated aluminum sheet 204 approaches the core material 220, the core material 220 is lowered and brought into contact with the aluminum sheet 204 as shown in FIG. Then, when the core member 220 is rotated in the contact state (see arrow FB), the aluminum sheet 204 is wound around the surface of the urethane foam 202 as shown in FIG. Then, when the aluminum sheet 204 has made a round, as shown by an arrow FC in FIG. The completed laminate 200 is shown in FIG. The cut end surface of the aluminum sheet 204 may be abutted and bonded as shown in FIG. 10 (B), or partially overlapped as shown in FIG. 10 (C). May be. When the aluminum sheet 204 is bonded to the urethane foam 202 as described above, drying is performed by electromagnetic induction heating as necessary, and the core material 220 is removed from the completed laminated material 200. The laminated material 200 is passed through a liquefied natural gas pipe 230 and used as a heat insulating material. As in this embodiment, the present invention can also be applied to the case of forming a laminated material other than the panel shape, and the basic effects thereof are the same, and the laminated material can be produced in a short time without causing distortion or the like. Can be formed.

In addition, this invention is not limited to the Example mentioned above, A various change can be added in the range which does not deviate from the summary of this invention. For example, the following are also included.
(1) The shapes and dimensions shown in the first to fifth embodiments are examples, and may be appropriately changed as necessary. Similarly, in the first embodiment, the steel plates and the like are exemplified as the metal plates 76A and 76B in the first embodiment. However, various known metal plates such as an aluminum plate may be provided. Further, the form of the metal layer can be appropriately changed as long as an eddy current flows, such as a metal foil or a mesh-like metal layer, instead of the metal plate. Moreover, a veneer board can be produced using this invention, and a press process is unnecessary in that case.
(2) The adhesive application device 20 and the tile sticking devices 40 and 120 shown in the above embodiment are also examples, and the design may be changed as appropriate so as to achieve the same effect. If necessary, the adhesive 26 and the tile 74 may be applied manually. Regarding the attachment of the metal plate in the third embodiment and the attachment of the surface material in the fifth embodiment, the apparatus may be used or may be performed manually.
(3) In the above-described embodiment, the base panels 70 and 140 and the base board are transported by the conveyor 16. However, this is also an example, and it may be configured to automatically transport as necessary.
(4) The base panel 140 shown in the second embodiment is also an example, and does not prevent preheating or drying with superheated steam from being applied to the tile 74 attached to the base panel 140 including a metal plate.

(5) The electromagnetic induction heating head 32 shown in the first embodiment is also an example, and the shape, dimensions, etc. may be changed within the range where the same effect is obtained. In the first embodiment, the electromagnetic induction heating head 32 is disposed on the lower side of the base panel 70. However, this is also an example, and the electromagnetic induction heating head 32 may be disposed on the upper side without causing warpage. When it is necessary to do so, it is good to arrange both on the top and bottom. The same applies to the other embodiments.
(6) In the first embodiment, a known hot melt adhesive is used as the adhesive 26. However, this is also an example, and may be a known two-component adhesive or a one-component epoxy. A known thermosetting adhesive such as an adhesive may be used. According to the present invention, even when a chemically reactive adhesive is used, the curing time is shortened by heating, and as a result, the curing time can be shortened.
(7) The heating timing and heating temperature shown in the process diagram of the above embodiment can be appropriately changed according to the material to be used. As for the heating method, as long as electromagnetic induction heating is used, the metal plate used for the base panel may be heated by electromagnetic induction, or it may be heated by superheated steam generated by electromagnetic induction heating. There may be. If the laminate to be manufactured does not contain metal, it will be bonded using IH superheated steam. For example, in the case of building materials, bonding is performed using IH superheated steam in principle. However, if there is a purpose of special use such as electromagnetic shielding or moisture prevention, heat can be generated by electromagnetic induction using metal. Good. When manufacturing a laminated material having such effects as electromagnetic wave shielding and moisture proof, the use of electromagnetic induction heating (IH heating) is superior in terms of improving productivity and reducing manufacturing costs. Can be differentiated.

(8) In the first embodiment, the tile 74 is attached to one surface of the base board. However, this is also an example, and the covering material to be attached is not limited to the tile 74. For example, the laminated material 250 illustrated in FIG. 11A is an example in which the cover materials 256A and 256B are attached to the front and back of the core material 252 such as urethane, and a metal layer 254A is provided between the core material 252 and the cover material 256A. A metal layer 254B is provided between the core member 252 and the cover material 256B. An adhesive 258 is provided between the core member 252, the metal layers 254 </ b> A and 254 </ b> B, and the cover materials 256 </ b> A and 256 </ b> B. After superimposing them as shown in the figure, the metal layers 254A and 254B are heated by the electromagnetic induction heating head from the outside of the cover materials 256A and 256B. Thereafter, when the adhesive 258 is pressed in a heated state, a front material 250 in which the front materials 256A and 256B are bonded to the front and back surfaces is obtained. In addition, when a tile is attached as a cover material, a pressing step is not necessary. Further, in the case of heating using superheated steam (IH superheated steam) as in the laminated material 260 shown in FIG. 11B, the metal layers 254A and 254B are unnecessary. In this case, as shown in FIG. 11 (B), the core material 262 with the adhesive 258 applied to the front and back is heated with superheated steam, and the surface covering materials 264A and 264B are stacked and then pressed. What is necessary is just to perform a press process suitably according to the kind of surface covering material. For example, when manufacturing doors, furniture members, veneers, decorative materials, decorative materials, etc., a magnetic material is not used for purposes other than electromagnetic shielding and moisture prevention. Used, these surface materials and decorative materials are bonded to the core material by IH superheated steam.
(9) The tile panels 60 and 150 and the laminated panel according to Embodiment 5 are used by being mounted on a wall surface, and can be widely applied to interior panels, partitions, furniture, doors, and the like.
