HEAT-ACCUMULATING COMPOSITION BASED ON MIXTURE OF ZINC NITRATE HEXAHYDRATE AND ITS OXIDE Russian patent published in 2021 - IPC C09K5/06 C01G9/00 C01G9/02 

FIELD: heat-saving and energy-saving technologies.

SUBSTANCE: heat-accumulating composition based on a mixture of zinc nitrate hexahydrate and its oxide includes zinc nitrate hexahydrate, zinc oxide, activated carbon and carboxymethylcellulose. The heat-accumulating composition is characterized by a temperature of a phase transition, which ensures the operability of the composition as temperature-supporting material, between 30 and 36°C. The specified composition is prepared by melting zinc nitrate hexahydrate in a mixture with zinc oxide for 30 min with constant mixing, holding for 10 min, sequentially adding activated carbon and carboxymethylcellulose, and further mixing for 3 h with a temperature control of 60°C.

EFFECT: invention makes it possible to obtain material for accumulating excess heat energy for the purpose of heating or air conditioning of premises, motor vehicle salons.
