HEAT STORAGE MEMBER AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2020094202
Kind Code:
A
Abstract:
To provide: a heat storage member which can prevent leakage of a heat storage material, has excellent durability and can improve designability; a method for producing the same; and a curable heat storage composition suitable for the production.SOLUTION: There is provided a heat storage member obtained by impregnating a curable heat storage composition comprising a polyol (a), a compound having an isocyanate group (b) and a heat storage material (c) in a porous base material, followed by curing. There is provided a method for producing the heat storage member by impregnating the curable heat storage composition comprising the polyol (a), the compound having the isocyanate group (b) and the heat storage material (c) in the porous base material at a temperature higher than a melting point of the heat storage material (c), followed by curing. There is provided the curable heat storage composition which comprises the polyol (a), the compound having the isocyanate group (b) and the heat storage material (c), wherein viscosity at the melting temperature of the heat storage material (c) is 10 to 500 mPa s.SELECTED DRAWING: None
