Abstract: A phase-change energy-storage structure for building insulation. The wall structure is provided with a wall base, an insulation layer, an oriented structural board, a shaped phase-change energy-storage insulation board, and an exterior decorative board in sequence from outdoor to indoor. The shaped phase-change energy-storage insulation board is composed of an inorganic composite phase-change material and a packaging sheet. The inorganic composite phase-change material has a phase-change temperature of 10 to 40° C., obtained by compounding an inorganic hydrated salt and a porous structural carrier. In the inorganic composite phase-change material, a mass percentage of the inorganic hydrated salt is 40 to 95%, and the inorganic composite phase-change material is coated with a fire resistant and corrosion resistant light-cured resin. The coldness in outdoor air in summer night can be stored in the phase-change energy-storage insulation board, which can be released into the indoor air during the day.
