Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a thermally expansive fire-resistant composition exerting not only excellent deformation prevention effect but also fire resistance performance and excellent in execution ability. SOLUTION: This thermally expansive fire-resistant composition contains a soft urethane foam, an inorganic expansion agent, and a deformation inhibitor, and the soft urethane foam is obtained from an aqueous polyurethane polymer. The inorganic expansion agent is a thermally expansive graphite and the deformation inhibitor is boric acid. The composition is manufactured by mixing, foaming and curing the expansion agent, an aqueous slurry of the deformation inhibitor, and the aqueous polyurethane polymer.
