Stabilized phase change material for floor heating heat storage
The invention discloses a stabilized phase change material for floor heating heat storage. The stabilized phase change material is prepared by the following steps: (1) mixing anhydrous calcium chloride and water until no precipitate is formed, thereby obtaining calcium chloride hexahydrate; (2) weighing the calcium chloride hexahydrate, sodium sulfate decahydrate, a phase change temperature regulator, a nucleating agent and water; (3) adding the sodium sulfate decahydrate, the phase change temperature regulator and the nucleating agent into the calcium chloride hexahydrate, stirring for dissolving, and adding water, thereby obtaining a phase change mother solution; (4) adsorbing the phase change mother solution by using an inorganic mineral fiber plate; (5) coating the object obtained in the step (4) by using a flexible plastic film; and (6) coating the object obtained in the step (5) by using an aluminum foil, thereby obtaining the stabilized phase change material for floor heating heat storage. According to the stabilized phase change material for floor heating heat storage disclosed by the invention, the space occupied by the thermal insulation layer can be reduced, and the finished product is neat in appearance, convenient in construction and clean. The reflector construction on the upper surface of the thermal insulation layer is avoided, and the cost is reduced. The temperature difference of a human settlement environment is reduced, the temperature fluctuation is reduced, and the comfort level is improved.
