Title:
METHOD FOR PREPARING SILICON DIOXIDE AEROGEL OR COMPOSITE PRODUCT THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/226710
Kind Code:
A1
Abstract:
Disclosed in the present disclosure are a method for rapidly preparing a silicon dioxide aerogel or a composite product thereof at low cost, and the silicon dioxide aerogel or he composite product thereof prepared according to the method. The method comprises: providing sodium silicate as a silicon source, and mixing the sodium silicate and desalted water at a volume ratio of 1:0.3-8 to form an aqueous sodium silicate solution, carrying out one-step catalytic gelatinization on the aqueous sodium silicate solution by means of an acid solution to form a wet gel, and optionally, compounding the aqueous sodium silicate solution with a carrier in the catalytic gelatinization process, and carrying out one-step replacement modification on the wet gel by means of an organic mixed solution, and carrying out ambient pressure drying to obtain the silicon dioxide aerogel or the composite product thereof.
