Abstract

The present invention relates to a powder phase change energy storage material and a preparation method thereof, wherein the powder phase change energy storage material comprises a carrier and an inorganic phase change energy storage material adsorbed on the carrier, the inorganic phase change energy storage material is prepared from an energy storage material, a nucleating agent, a modifier and water, a weight part ratio of the energy storage material to the nucleating agent to the modifier to the water to the carrier is 35-50:0.1-1:0-15:35-50:20-25. According to the present invention, during the preparation, respectively weighing the energy storage material, the nucleating agent, the modifier and the water, uniformly stirring and mixing, adding the carrier, and uniformly stirring and mixing, wherein the interval time between the two stirring does not exceed 10 min; and compared with the material in the prior art, the material of the present invention has the following characteristics that the suitable packaging material and the suitable ratio are selected and the inorganic energy storage material is successfully and uniformly adsorbed into the system, such that the packaging problem of the material is solved, and the phase separation produced due to the long-term circulation of the material is solved.

Description

technical field [0001] The invention relates to the field of energy-saving and environment-friendly materials, in particular to a powder phase-change energy storage material and a preparation method thereof. Background technique [0002] As the global energy shortage becomes more and more serious, the storage and utilization of heat source, one of the main energy sources, has become a research and development hotspot. Thermal energy storage methods include: sensible heat, latent heat and chemical reaction heat. [0003] Phase change energy storage materials absorb or release a large amount of heat when the material undergoes a phase change to realize energy storage and utilization, and effectively solve the contradiction between energy supply and demand in terms of space and time. This type of material is widely used in intermittent or unstable thermal management systems, such as thermal management of aviation high-power components, solar energy utilization, "peak shifting ...
