<P>PROBLEM TO BE SOLVED: To provide a thermally expandable resin composition, capable of closing a gap of building materials, a through-hole or the like even if it cannot be perfectly closed by the thermally expanded residue of the thermally expandable resin composition. <P>SOLUTION: [1] The thermally expandable resin composition includes: a thermally expanding component, a binder resin and an inorganic filler, the thermally expanding component includes a first thermally expanding component having a thermally expansion start temperature of 140-250°C and a second thermally expanding component having a thermal expansion start temperature of 251-350°C. [2] In the thermally expandable resin composition of [1], the first thermally expanding component is thermally expandable graphite having a thermal expansion start temperature of 140-250°C, the second thermally expanding component is thermally expandable graphite having a thermal expansion start temperature of 251-350°C, and the binder resin includes at least one selected from the group consisting of thermosetting resin, thermoplastic resin and rubber resin. <P>COPYRIGHT: (C)2013,JPO&INPIT |
