2. Description of the Related Art Conventionally, polyurethane foam has been used in a wide range of fields such as building materials and daily necessities. However, since it is flammable, once ignited, there is a drawback that a flame easily propagates. A fire was reported during construction. Therefore, it cannot be applied to building materials that require flame retardancy as it is, and a method of adding a flame retardant or a flame-retardant polyurethane foam modified with isocyanurate is known as a method of flame retardation.

However, the method of adding a flame retardant does not sufficiently increase the flame retardancy of a rigid urethane foam, and has been difficult to use especially in the field of building materials. In addition, although the isocyanurate-modified flame-retardant polyurethane foam has improved flame retardancy, the problem of toxic gas such as hydrocyanic acid gas and carbon monoxide generated with smoke during combustion has not been improved.

The polyurethane foam used in the present embodiment was manufactured by Formlite HM-1075, manufactured by Polyurethane Chemical Co., Ltd., and was previously formulated into two liquids, liquid A and liquid B. 100 parts by weight of liquid A (polyol) mixed with 50 parts by weight of an aqueous film-forming inorganic compound and 25 parts by weight of activated carbon impregnated with an aqueous film-forming inorganic compound, and 100 parts by weight of liquid B (polyisocyanate) as liquid B The mixture was mixed at a liquid temperature of 20 ° C. and stirred for 10 seconds to foam. Also, B
When a liquid (polyisocyanate) mixed with an aqueous film-forming inorganic compound and activated carbon impregnated with an aqueous film-forming inorganic compound is mixed with liquid A (polyol) and foamed, foaming occurs but the uniformity of the foam is increased. A preferable result was obtained by mixing the aqueous film-forming inorganic compound and the activated carbon impregnated with the aqueous film-forming inorganic compound with the liquid A (polyol) and foaming the mixture with the liquid B (polyisocyanate). The obtained foam was ignited by a burner, but the flame generated by the foam was small and did not spread. In addition, the amount of smoke and the irritating odor were very small. In addition, when the burner was extinguished, the foam emitted a flame in a few seconds.
