Moreover, since it has excellent heat insulation properties, it is used as various building materials such as wall materials for unit baths.

However, if the thickness of the face plate is reduced, the surface strength is reduced, and dents and openings due to impact strength are caused. Since this causes generation, a reinforcing sheet 13 made of a cloth-like material such as glass fiber is interposed between the face plate and the foamed resin material in order to increase the strength of the surface.

ていた。As described above, the conventional method for manufacturing a laminated panel of this kind is to dispose a reinforcing sheet on both sides of a foamed steel plate and further dispose a face plate outside the reinforcing sheet. Applying an adhesive in advance to both sides of the styrene foam plate and the opposing surfaces of the styrene foam plate and the face plate, or sandwiching an adhesive resin film or the like, laminating them in a sandwich shape, and then bonding them together by applying pressure Therefore, the productivity is extremely low and the production cost is inevitably increased, which has caused the price of products using such laminated panels to rise.

Then, the heating / pressing plate 14 a is lowered again, and the foamed resin body 11 is heated and pressed via the face plate 13. The application and release of such a pressing force can be performed three to three times if the cycle is one time / 0.5 to 5 seconds.
The heating and pressurizing plate 14a on the upper side, which is finally lowered ten times, comes into contact with the spacers 15 arranged on both sides of the laminated body 10.

する。As a result, a bubble crush layer (melt layer) having substantially the same thickness is formed on both sides of the foamed resin body 11 which comes into contact with the double-sided board 13. When such a heating and pressurizing step is completed, a cooling press is then used for about 1 hour.
Press at a pressure of 0-70 Kg / cm 2 for about 5-15 minutes. As a result, the surface of the foamed resin body 11 becomes a sheet-shaped bubble crush layer and is strongly bonded to the face plate 13 by an adhesive.

Is inherently heat-insulating, the molten portion is formed only at the contact portion with the face plate 13, and its thickness is determined by the descending stroke of the upper heating and pressing plate 14a. That is, it is the spacer 15 that limits the downward stroke.

That is, the reinforcing layer 12 is formed by forming a bubble crushing layer in a sheet shape on the surface portion of the foamed resin body 11 that comes into contact with each face plate 13. The following table shows specific dimensions, heating temperatures, pressures, and the like of the components in the laminated panel P thus formed.

率的に製造することができる。As described above, according to the method for manufacturing a laminated panel of the present invention, a rigid face plate is arranged on both surfaces of one foamed resin body with an adhesive or the like interposed therebetween to form a laminate.
By pressing the laminate while heating with a heating and pressing plate from the outside of both face plates, the surface portion of the foamed resin body that is in contact with the face plates is melted over a predetermined thickness to form a bubble collapse layer. Since a sheet-like reinforcing layer is formed, it is not necessary to arrange a special reinforcing sheet as in the related art, and the reinforcing layer can be formed only by joining the face plate to the foamed resin body. Can be manufactured very efficiently.
