(57) [Summary] [PROBLEMS] By forming a carbonized layer which is expanded and foamed by heating, it is possible to prevent combustibles from being fired and to prevent smoke, flame, gas generated by combustion, etc. from flowing out. And a water-resistant foam-type fire-retardant composition. The foam type fire-retardant composition comprises (A) a thermoplastic resin and / or a rubber-based material, (B) a phosphorus compound, (C) a heat-expandable graphite and / or (F) a polyfunctional alcohol. Wherein (B) the phosphorus compound, (C) the heat-expandable graphite and / or (F) the polyfunctional alcohol form a discontinuous dispersed phase, and the distance between the surfaces of the dispersed phase is 0.1 μm or more. A foamable fire-resistant resin composition characterized by the following. |
