Abstract: Used is a method for producing a thermal insulation sheet, including: composite-forming including impregnating a nonwoven fabric with a basic sol prepared by adding a carbonate ester to a water glass composition to form a hydrogel-nonwoven fabric composite; surface-modifying including mixing the composite with a silylating agent for surface modification; and drying including removing liquid contained in the composite through drying at a temperature lower than the critical temperature of the liquid under a pressure lower than the critical pressure of the liquid. Used is a thermal insulation sheet including an aerogel and a nonwoven fabric, where the thermal insulation sheet exhibits a compressibility of 40% or lower at 0.30 to 5.0 MPa.

Abstract: An insulating material is used that contains a silica xerogel, and a nonwoven fabric fiber capable of generating carbon dioxide by reacting with atmospheric oxygen at a temperature of 300° C. or more. The insulating material uses oxidized acrylic as the nonwoven fabric fiber. A device uses the insulating material installed as a part of a heat insulating or a cold insulating structure, or installed between a heat-generating part and a casing.

Abstract: An alkoxysilane containing reactive organic functional groups is prepared as one of raw materials. The reactive organic functional groups are caused to react to bond with each other in advance so as to form an oligomer. The oligomer is swollen in an alkoxysilane of an identical or different kind, so that a sol solution is prepared and the sol solution is cured through a sol-gel reaction.
