FIG. 1 is a partially cutaway perspective view illustrating an embodiment of the composite panel of the present invention, and FIG. 2 is a partially exploded perspective view of a door showing an example of use of the composite panel of the present invention.

As shown in FIGS. 1 and 2, the composite panel 1 includes a core material 3 divided into a large number of cells by partition walls 2 partitioned in the thickness direction, a surface 3a side of the core material 3 and It is composed of a surface decorative plate 4 attached to the back surface 3b side.

As the core material 3, what is generally called a honeycomb core, a roll core or the like can be used. The cross-sectional shape is not particularly limited in the present invention, and may be, for example, hexagon, triangle, quadrangle, other polygon, circle, or other cross-sectional shape.
As the material of the core material 3, aluminum, synthetic resin such as vinyl chloride resin, virgin pulp paper, recycled paper, or the like can be used, but recycled paper can be preferably used from the viewpoint of resource protection.

The surface decorative plate 4 is a surface material for giving a design feeling due to the texture of wood, the texture of cloth, and an abstract pattern, and has a veneer coated on the surface or attached with a decorative paper ( A board) or veneer plywood, a wood fiber board, a metal board, etc. can be used. As the decorative paper, printed on a resin film such as vinyl chloride resin, printed on thin paper, or impregnated with a synthetic synthetic resin such as urea / formalin resin or melamine resin on thin paper, and then printed. A thing, a veneer, etc. can be used. The thickness of the surface decorative plate 4 is not particularly limited in the present invention, but is usually 2 to 1 for example.
It is 0 mm.

The composite panel 1 of the present invention is characterized in that the paperboard 5 is bonded between the core material 3 and the surface decorative board 4.

As the paperboard 5, it is preferable to use a paperboard whose expansion and contraction due to temperature and humidity are very small.

The adhesive for adhering the paperboard 5 to the core material is not particularly limited in the present invention. For example, a synthetic resin water-based emulsion type adhesive, a hot-melt type or a solvent type adhesive is used. Etc. can be used.

When the paperboard 5 is attached to the front and back surfaces of the core material 3 by using a synthetic resin aqueous emulsion adhesive,
The edges of the front and back partition walls of the preheated core material are pressed and bent to increase the adhesive application area, then the adhesive is applied, and then the core material is further preheated and then the adhesive is applied to bond the paperboard. Preferably. In this way, by preheating the core material before applying the adhesive, it is possible to eliminate the influence of water in the adhesive, and thus it is possible to prevent warping or distortion of the paperboard due to water. .

The order of attaching the paperboard 5 and the surface decorative board 4 to the core material 3 may be such that the paperboard 5 is first adhered to the core material 3 and then the surface decorative board 4 is adhered thereto. Board 4
It is also possible to attach the adhered material to the core material 3.
Incidentally, 6 is a partition plate for protecting the core material 3 from moisture and pressure from the outside.

Since the surface decorative board 4 in the composite panel 1 of the present invention is adhered to the entire surface of the paperboard 5, the paperboard 5 corrects the deformation of the surface decorative board 4, and the surface decorative board 4 is exposed to the atmosphere. It is possible to prevent warping and deformation due to moisture.

Further, in the composite panel of the present invention, a window can be formed by opening a part of the composite panel according to the purpose of use and mounting a glass.

Next, an example of using the composite panel of the present invention will be described.

As shown in FIGS. 1 and 2, the composite panel of the present invention is used for a door of a building such as a house.
