Document Type and Number:
WIPO Patent Application WO/2021/194198
Kind Code:
A1
Abstract:
The present invention provides a thermal insulation coating composition and a thermal insulation material comprising same, the composition comprising: an aerogel surface-treated with a polyoxyethylene alkyl ether (PEO) of chemical formula 1; a silica filler; an inorganic pigment; a polymer resin; and a dispersion medium.
The thermal insulation coating composition according to the present invention comprises a surface-treated aerogel so as to exhibit good miscibility between components and improved stability, thereby providing excellent water resistance together with the characteristic thermal insulation performance of aerogel, and thus can improve dew-proof characteristics that suppress dew condensation.
