PROBLEM TO BE SOLVED: To provide a fireproof rubber composition that can retain sufficient shape stability in the fine foam state, even when exposed to baking heat, and provide a fireproof rubber composition that can give excellent working efficiency to the fireproof covering material obtained by molding the fireproof covering material. SOLUTION: This invention provide an unvulcanized fireproof rubber composition comprises 10 to 60 pts.mass of an adhesive, 10 to 100 pts.mass of a thermally expandable graphite, 50-170 pts.mass of aluminum phosphite, 50 to 170 pts.mass of inorganic filler, 0.1 to 10 pts.mass of vulcanizer, 0.1 to 10 pts.mass of a vulcanization accelerator, per 100 pts.mass of the base rubber composed of 30 to 50 pts.mass of liquid rubber and 50 to 70 pts.mass of butyl rubber and is to be kneaded at 60 to 100°C. Further, the fireproof covering material obtained by molding the fireproof rubber composition, the fireproof covering method using the fireproof covering material, and the like are also provided.
