Title:
METHOD FOR PRODUCING POLYSILOXANE POROUS BODY, POLYSILOXANE POROUS BODY, HEAT-INSULATING MATERIAL, AND HEAT-INSULATING CONTAINER
Document Type and Number:
WIPO Patent Application WO/2022/163178
Kind Code:
A1
Abstract:
The present invention provides a method for producing a polysiloxane porous body, the method making it possible to produce a polysiloxane porous body having exceptional flexibility. The production method according to the present invention includes: preparing a composition including a tetraalkoxysilane, a methyl trialkoxysilane, a dimethyldialkoxysilane, and water, and gelling the composition to form a gel; and drying the gel to obtain a polysiloxane porous body. When the total of the tetraalkoxysilane content, the methyl trialkoxysilane content, and the dimethyldialkoxysilane content in the composition is taken as 100 mol%, the tetraalkoxysilane content is 10.5-20.0 mol%, and the dimethyldialkoxysilane content is 11.0-41.0 mol%.
