The invention discloses phase-change putty and a preparation method thereof. The preparation method comprises the steps that a natural inorganic porous material serves as a carrier, a hydrated salt phase-change energy storage material is loaded, a hydrated salt-porous carrier compound is prepared, then the hydrated salt-porous carrier compound is wrapped with water-soluble silicon or water glass, a hydrogel-coated hydrated salt-porous material compound type phase change energy storage material is prepared after dehydrating, and the hydrogel-coated hydrated salt-porous material compound type phase change energy storage material is mixed with putty to obtain the phase change putty. According to the phase-change putty, the hydrated salt phase-change material is isolated from the putty, the heat storage and release performance of the hydrated salt phase-change material is kept, and possible hydrated salt leakage and migration in the mixing process of the hydrated salt phase-change material and the putty and in th
