The invention relates to the field of a
phase change material, in particular to an inorganic hydrated salt
phase change material and a preparation method thereof. The inorganic hydrated salt
phase change material is prepared from the following components by weight percent: 65 to 75 percent of heat storage agent, 8.5 to 10 percent of
xanthan gum, 4.5 to 15 percent of
heat conducting material, 4.5 to 8 percent of modifier and 2 to 10 percent of nucleating agent. The inorganic hydrated salt
phase change material has the advantages that the cold phenomenon can be completely eliminated, the energystorage density is high, the phase change volume is small, the inorganic hydrated salt
phase change material is nontoxic, non-volatile, stable in performance, good in
repeatability and convenient in use; the service life of the
phase change material is effectively prolonged; and the
phase change temperature of the phase change material is 10 to 30 DEG C, the
heat conducting performance is good, the phase change reversibility is good, the phase changetransition is fast, and the heat storage performance is good.
