Preparation Method of Aluminum Silicate Fiber-Reinforced Aerogel Felt and Impregnation Reactor
The present disclosure provides a preparation method of an aluminum silicate fiber-reinforced aerogel felt, including the following steps: mixing orthosilicate, ethanol, and water evenly, adding an NH4F solution and ammonia water successively, and stirring evenly to obtain a silica sol; winding an aluminum silicate fiber felt into a roll and mounting on a rotatable central shaft of a impregnation reaction kettle; where a plurality of injection holes are equidistantly provided on a surface of the reaction kettle; the central shaft of the reaction kettle drives the aluminum silicate fiber felt to rotate and slowly inject the silica sol into the surface of the fiber felt through the injection holes to conduct the impregnation; allowing the fiber felt-gel composite to stand to conduct aging; placing the aged fiber felt-gel composite in absolute ethanol to conduct solvent replacement to remove moisture; and drying to obtain the aluminum silicate fiber-reinforced aerogel felt.
