Description of the Related Art Corrugated cardboard is widely used as a heat insulating and cushioning material in packaging, but because it is paper, it is easily burned and has poor water resistance, so its use has been limited. . In addition, various materials reinforced with a foamed resin or an organic binder are used as a heat insulating material. However, these materials cannot avoid burning by fire or generation of toxic gas, etc. Even so, its use has become a problem. Furthermore, since fire retardants for fabrics and papers are usually made of organic substances or halogen-containing substances, it is necessary to generate toxic gas by fire. However, it was difficult to obtain a practical building material.
