Title:
METHOD FOR PRODUCING THERMAL INSULATION MATERIAL, AND COMPOSITE THERMAL INSULATION MATERIAL
Document Type and Number:
WIPO Patent Application WO/2019/027046
Kind Code:
A1
Abstract:
This composite thermal insulation material 1 is able to be obtained by a process wherein: an aqueous solution, which contains water, a surfactant and a gel starting material that is obtained by blending a trialkoxysilane compound and a tetraalkoxysilane compound so that the amount of the tetraalkoxysilane compound relative to the total volume of alkoxysilane compounds is within the range of from 4% to 10% (inclusive), while containing substantially no alcohol, is heated after hydrolyzing the alkoxysilane compounds so as to produce a sol, thereby causing a polymerization reaction of the alkoxysilane compounds and forming a gel; and the thus-obtained gel is cleaned with an alcohol, is then subjected to solvent exchange by means of hexane, and is subsequently dried.
