アが開発され実施されるに至っている。2. Description of the Related Art Conventionally, doors for homes such as furniture, kitchens and fittings have a panel made of wood laminated wood, honeycomb core, etc. as a core material, and the surface of this core material has a surface makeup such as wallpaper, cloth and paperboard. A structure in which a frame material is attached to a side edge after the materials are bonded together is widely used. In recent years, there has been a strong demand for weight reduction, and a lightweight door has been developed in which a foam material, which has a weight advantage, is used as a core material and a rigid material such as paper or a metal plate and a surface decorative material are attached to both sides of the core material. Has arrived.

る。以下、図面を参照しつつ詳述する。However, both the conventional door having the rigid panel as the core material and the lightweight door having the foam material as the core material may cause warping or twisting due to the permeation of moisture. However, there are major drawbacks such as delamination of the face material due to delamination due to moisture, warpage, twisting, or characteristics of the material. It is an object of the present invention to provide a lightweight door core material that does not warp or twist due to the permeation of moisture and is firmly bonded to eliminate the risk of delamination. Hereinafter, a detailed description will be given with reference to the drawings.

ったものである。The present invention, as described above, includes the decorative material (4), the aluminum foil (2), the polyethylene layer (3), the aluminum foil (2), the synthetic resin foam (1) and the aluminum from the surface side. A door core panel, which is formed by layering a foil (2), a polyethylene layer (3), an aluminum foil (2), a decorative material (4), and a rigid resin foam (1) in a layered manner. A strong and shape-maintaining force is created by the front and back symmetrical multi-layer structure made of different materials, resulting in a core panel that does not warp or distort. In particular, in the present invention, the polyethylene layer (3) is formed in place of the chip cardboard that has been widely used in the past, and it is possible to completely eliminate the risk of delamination or warpage caused by moisture absorption of the chip cardboard. It was made. The waterproof effect of the polyethylene layer (3) is more effective when used in combination with the aluminum foil (2), and the polyethylene core (3) becomes a door core material capable of preventing warpage, dew condensation, etc. in an area with a large humidity difference or in a cold area.
