亀裂や角部の欠けが発生し易い欠点を有していた。Traditionally, fireproof boards used for building walls, etc., have been made by sandwiching insulation materials such as glass wool with gypsum boards, and fireproof boards such as lightweight concrete boards have been found. When constructing boards to meet prescribed fire safety standards, it is necessary to stack several boards, and the weight of each board is relatively large, resulting in a considerable weight and wall thickness as a whole, and cracks in the boards themselves. It had the disadvantage of being prone to chipping and corner parts.

When the surface of the fire prevention board 1 is heated by flame, a carbonized layer is firmly formed on the corrugated paperboard 3.3a due to dehydration and carbonization, so that the fire prevention board 1 is heated by flame. In addition, when the core material 2 containing thermally expandable graphite is heated, the thermally expandable graphite expands and decomposes the reactants between the graphite layers and releases acidic gas, producing acidic oxidizing gas. The resin component is rapidly carbonized in the body, and a carbonized body is formed integrally with the expanded graphite particles, thereby suppressing the generation of flame.

ことが出来る。(Effects of the Invention) In short, the present invention has corrugated paper 3.3a mainly made of phosphoric acid cellulose and glass fiber attached to the outer surface of the core material 2 made of urethane foam, so it is more effective than plasterboard or lightweight concrete board. Since the density of the urethane foam and corrugated paper is low, it is possible to reduce the weight of the fire prevention board 1, and since the corrugated paper 3.3a has high strength, damage such as cracks and chips can be prevented. Furthermore, even when the corrugated paperboard 3.3a is heated with flame, a strong carbonized layer is formed due to the dehydration and carbonization effect, so by suppressing the generation of flame at such locations, excellent fire prevention function can be achieved.

Corrugated cardboard paper 3
When the core material 2 is heated through % 3a, the thermally expandable graphite expands due to the heating, and at the same time releases acidic gas to rapidly carbonize the resin component and integrate it with the expanded graphite particles. Since it forms a carbonized body, the core material 2 also suppresses the generation of flames, and in combination with the above effects, it can achieve an even better fire prevention function. Because it is not an organic compound, it has a soft foam,
Fire retardant without sacrificing the properties of rigid foam.
Its practical effects, such as being able to improve heat resistance, are tremendous.
