Document Type and Number:
WIPO Patent Application WO/2020/184467
Kind Code:
A1
Abstract:
Provided is a heat storage material composition that hardly evaporates at all and has a sufficiently stable super-cooled state. The heat storage material composition according to one mode of the present disclosure contains sodium acetate, water, and an alcohol. The alcohol contains at least one selected from the group consisting of 1,2-butanediol and a divalent alcohol having 5 or 6 carbon atoms. The divalent alcohol is a straight chain alcohol, for example. For example, the two hydroxyl groups included in the divalent alcohol are bound to the carbon atom at position 1 and the carbon atom at position 2 of the divalent alcohol. The alcohol contains, for example, at least one selected from the group consisting of 1,2-butanediol, 1,2-pentanediol, and 1,2-hexanediol.
