HEAT INSULATION MATERIAL AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a heat insulation material having incombustibility and adiabaticity.SOLUTION: There is provided a heat insulation material containing: isocyanate; an active hydrogen-containing compound; water; a reaction catalyst; and ettringite with a fiber length of 5 to 40 μm, and having a density of 350 kg/m. There is also provided a method for producing the heat insulation material obtained by incorporating ettringite with a fiber length of 5 to 40 μm into a composition obtained by mixing: isocyanate; an active hydrogen-containing compound; water; and a reaction catalyst. A foam control agent, aluminum hydroxide or heat expansible graphite may be incorporated therein.SELECTED DRAWING: None
