An object of the present invention is to provide a thermally expandable resin composition which is excellent in flame resistance and stress at break point and has a low elastic modulus.nn n n The solution of the present invention is a thermally expandable resin composition containing an epoxy resin, a thermally expandable graphite, and an inorganic filler. The epoxy resin includes: a bisphenol-type epoxy and an aliphatic epoxide, and 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 fire-resistant coating materials for columns, beams, walls, etc., the use of fire-resistant window frames, the use of fire-resistant zoning structures, and the use of fire-resistant doors. |
