Thermal expansion resin composition

摘要

[Problem] To provide a thermal expansion resin composition which gives molded bodies having excellent flame resistance and stress at break, and relatively low elasticity. [Solution] This thermal expansion resin composition contains an epoxy resin, a thermally expandable graphite, and an inorganic filler. The epoxy compound contained in the epoxy resin contains a brominated epoxy compound, and contains, in addition to the brominated epoxy compound, a bisphenol-type epoxy compound and/or an aliphatic epoxy compound, wherein the weight ratio of the brominated epoxy compound to the bisphenol-type epoxy compound and/or aliphatic epoxy compound is in the range 99:1-1:99. This thermal expansion resin can be applied in refractory coating materials for pillars, beams and walls, in fireproof
