Plywood manufactured by laminating these veneers with an adhesive (for example, urea resin), wood chips, and wood fibers as the main raw material, molded with an adhesive (for example, melamine resin), and produced by pressing and heating. Known wooden boards such as particle boards, wood chip cement boards, and inorganic boards such as wood wool cement.

い。また、近年の合板用原木産地国の事情や熱帯林保護
の提唱の影響で材料の安定供給がなく、品質のばらつき
が非常に大きいという問題がある。In the case of the conventional plywood,
Mostly due to urea resin adhesion, and the heat resistance is very weak because the veneer and the veneer adhesive layer are destroyed by heat. In addition, there is a problem that there is not a stable supply of materials due to the circumstances of the country of origin of wood for plywood and the proposal of protection of tropical forests in recent years, and the quality is very large.

ガスが発生するという問題がある。Further, in the case of a wooden board, since a thermosetting resin such as urea resin, melamine resin, and phenol resin is used as an adhesive agent, even when it is molded and processed, it is changed with time and exposed to a flame. There is a problem that toxic gas such as formalin odor is generated.
【０００６】また、無機質ボードの場合は、重量大や加

困難であるという問題がある。In terms of workability, wood-based boards such as plywood, particle board, and medium-quality fiberboard (abbreviated as MDF) use a thermosetting resin as an adhesive, so punctures and the like during molding are performed. It is easy to occur. Further, since inorganic boards such as wood chip cement board and wood cement board have a large weight and poor machinability, there is a problem that processing due to shape change is very difficult.

Another object of the present invention is to provide a novel molded board which is excellent in flame retardancy and which is free from generation of toxic gas such as formalin odor which has been a problem in woody boards in recent years and which is extremely environmentally friendly.
