Title:
COATING MATERIAL FOR HEAT INSULATION MATERIAL AND HEAT INSULATION MATERIAL
Document Type and Number:
WIPO Patent Application WO/2020/040171
Kind Code:
A1
Abstract:
Provided is a coating material for a heat insulation material, comprising a silica aerogel, an aqueous emulsion binder, and a polysaccharide. The thickening and colloid stabilizing effects of the polysaccharide suppress the separation of the silica aerogel and improve the dispersibility thereof in the coating material. Also provided is a heat insulation material comprising a cured product of the coating material for a heat insulation material in at least part of a surface or the inside of the base material. In addition to the silica aerogel, the cured product comprises the polysaccharide which is less likely to form a heat conduction path compared with fibrous materials. With this configuration, the thermal conductivity of the cured product is lowered and a heat insulation material having an excellent heat insulation effect is achieved.
