PROBLEM TO BE SOLVED: To provide a fire resistant insulation material, producible without adding a flammable pore-generating agent and an inorganic binder, and having small bulk density and excellent heat conductivity by controlling the pore size to be small, and a method for producing the same.SOLUTION: The fire resistant insulation material is produced by adding a surfactant as a foaming agent, a forming assistant and water to a fire resistant inorganic fiber and an inorganic powder that are solid raw materials and kneading them, molding the kneaded product, subsequently drying and firing the same. The obtained fire resistant insulation material is reinforced with fire resistant inorganic particles in which three dimensionally interlaced fire resistant inorganic fiber is sintered, and has a net-like structure or a lattice-like structure including micropores formed of the surfactant in the inside, and has 0.40-0.90 bulk density and 0.20-0.90 W/(m*K) heat conductivity. |
