Hydrophobic silica aerogel heat-insulation composite material
The invention relates to a hydrophobic silica aerogel heat-insulation composite material. The composite material consists of silica aerogel and an inorganic fiber product, wherein the silica aerogel is doped with a flame retardant and an infrared blocking agent; the inorganic fiber product comprises one or more of glass fibers, quartz glass fibers, aluminium silicate fibers, ceramic fibers, alumina fibers, zirconia fibers, rock wool fibers and basalt fibers, and the porosity of the inorganic fiber product is higher than 50%. The composite material has the overall waterproof performance, the extremely low heat conductivity coefficient and the excellent high-temperature heat-insulation performance, can pass an incombustibility test under the condition that the material is ensured to be hydrophobic as a whole, and reaches level A1 according to the incombustibility test; the preparation process is simple, the production cycle is short, the cost is lower, the equipment requirement is low, and reaction conditions are controllable.
