COMPOSITE INSULATION INCLUDING INORGANIC AEROGEL AND MELAMINE FOAM
PROBLEM TO BE SOLVED: To provide a monolithic composite material that comprises an inorganic aerogel and melamine foam and has a thermal conductivity λ of 5 to 20 mW/m K, measured according to the method of the guarded hot plate of the NF EN 12667 at 20°C and atmospheric pressure.SOLUTION: There is provided a composite material comprising a monolithic inorganic aerogel reinforced by a preformed open-cell melamine foam, the composite material having a thermal conductivity λ of 10 to 15 mW/m K, measured according to the method of the guarded hot plate of the NF EN 12667 at 20°C and atmospheric pressure, and having a macro porosity of less than 5%, and comprising aerogel of 90 to 98 mass% based on the total weight of the composite. A method for producing a monolithic composite material comprising a) casting an inorganic sol into a reactor in which a preformed open-cell melamine foam was previously placed, b) gelating the sol into a lyogel, and c) drying the lyogel is also provided.SELECTED DRAWING: None
