To provide a thermal expansion resin composition which gives molded bodies having excellent fire resistance and stress at break, and relatively low elasticity. This thermal expansion resin composition contains an epoxy resin, a thermally expandable graphite, and an inorganic filler. The epoxy resin contains a bisphenol-type epoxy compound and an aliphatic epoxy compound, wherein the weight ratio of the bisphenol-type epoxy compound to the aliphatic epoxy compound is in the range 95:5-60:40. This thermal expansion resin composition can be applied in refractory coating materials for pillars, beams and walls, in fireproofsashes, in fireproof compartment passage structures, in fireproof doors, etc. |
