An object of the present invention is to provide a heat-expandable resin composition which is excellent in fire resistance and fracture point stress and has a low modulus of elasticity. The solution of the present invention is a heat-expandable resin composition comprising an epoxy resin, a heat-expandable graphite, and an inorganic filler, the epoxy resin comprising: a bisphenol-type epoxide and an aliphatic epoxide, the bisphenol-type epoxy The weight ratio of the compound to the aforementioned aliphatic epoxide is in the range of 95:5 to 60:40. It can be applied to the use of refractory coating materials such as columns, beams, walls, etc., the use of fire sashes, the use of fire-resistant zone penetration structure, and the use of fire doors. |
