A fire-resistant polyurethane composition and a fire-resistant product comprising the fire-resistant polyurethane composition. The fire-resistant polyurethane coating composition comprises: an aromatic isocyanate component, a polyol component, and an intumescent component; wherein the aromatic structure in the polyurethane backbone is =24wt%. The fire-resistant polyurethane composition could provide surprisingly good intumescent layer toughness as well as good insulation performance. Una composición de poliuretano resistente al fuego y un producto resistente al fuego que comprende la composición de poliuretano resistente al fuego. La composición de recubrimiento de poliuretano resistente al fuego comprende: un componente de isocianato aromático, un componente de poliol y un componente intumescente; en donde la estructura aromática en la cadena principal de poliuretano es =24 % en peso. La composición de poliuretano resistente al fuego podría proporcionar una dureza de capa intumescente sorprendentemente buena, así como un buen rendimiento de aislamiento.
