A novel material for making a urethane material incombustible is provided. [Solution] (A) a thermally expandable graphite, (B) a microcapsule in which ammonium polyphosphate powder is coated with a resin, and (C) a refractory powder containing aluminum hydroxide powder, melamine resin powder and pentaerythritol powder. is there. By blending it into a polyurethane resin-forming composition comprising a first liquid containing polyol and a second liquid containing polyisocyanate, the polyurethane resin can be made incombustible.
