BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a sandwich panel for walls having excellent insulation and rigidity,

The present invention relates to a sandwich panel for a wall, and more particularly to a sandwich panel excellent in heat insulation and rigidity.

In general, sandwich panels are special plywood which is made by sandwiching different kinds of materials and bonding them with adhesive. In general, the surface plate is made of a material having high strength such as a plastic plate, an aluminum plate, and a stainless steel plate, and the core material is formed by inserting paper, wood, foam plastic material, etc. in consideration of heat insulation, sound insulation and strength.

Conventionally, a sandwich panel is a building material in which a core material is inserted between surface plates, and a structure such as a house, a factory, or a warehouse is mainly assembled. Sandwich panels are less expensive than other building materials and have shorter construction periods, but they are vulnerable to stiffness, heat insulation or sound insulation. In addition, the sandwich panel is susceptible to the strength problem of the structure due to the weak corrosion resistance of the sandwich panel surface as well as the problem that the core material between the surface plates melts easily in the heat when the fire occurs or toxic smoke is generated.
