NOVELTY - Preparing aerogel material involves adding the gel to the mold laid with reinforcing fibers to mix with the reinforcing fibers, where the mass ratio of the gel to the reinforcing fibers is 3:1, standing at room temperature for 20 hours to obtain reinforced fiber composite gel, placed the reinforced fiber composite gel into a supercritical fluid drying equipment, pre-filled with 6.5 megaPascal nitrogen, and then heated to 246 degrees C at a rate of 3 degrees C/minutes, and exhausted gas at one end while heating, filled one end with nitrogen, where the volume of the discharged gas is the same as the volume of the filled helium, ensured that the supercritical fluid drying equipment maintains a constant pressure, kept warm for 2 hours, and then slowly released the pressure at a rate of 50 KiloPascal/minutes to obtain the aerogel insulation composite material. USE - Method for preparing aerogel material used for electronic products. ADVANTAGE - The method isolates the heat conducted by the longitudinal direction.
