Abstract

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.

Description

technical field [0001] This product relates to an energy storage material used in ground heating heating systems. Background technique [0002] In the process of floor heating construction, in the process of laying floor heating pipes, composite insulation layer materials should be laid. The insulation layer materials in the prior art mainly consist of the following two types: [0003] 1. Laying organic insulation board, laying thickness 20-30mm, its disadvantage is that it is flammable. [0004] 2. Lay foam cement, make foam concrete on site and pour about 40mm on site. The disadvantage is that the thickness is large and the construction time is long. [0005] What the above two kinds of materials have is only thermal insulation performance, and does not possess the function of temperature regulation. Contents of the invention [0006] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a shaped phase change material for flo...
