PURPOSE:An inexpensive heat accumulative material capable of controlling endothermic and exothermic temperature by changing the composition of a system, having stable endothermic and exothermic properties, comprising sodium acetate formamide and water. CONSTITUTION:The titled heat accumulative material comprising sodium acetate, formamide and water in a composition ratio of preferably 25-70wt%, <=55wt% (with the proviso that 0wt% is omitted), and 15-50wt% respectively, preferably having the composition consisting of NaCH3COO.3H2O and HCONH2 as components of both ends, and <=40wt% (with the proviso that 0wt% is omitted) total amount of HCONH2 content. |
