Title:
ENERGY-STORAGE TEMPERATURE CONTROL MATERIAL, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/062044
Kind Code:
A1
Abstract:
The present invention provides an energy-storage temperature control material, and relates to the technical field of temperature control materials. An organic synthetic fiber-based phase change material in the energy-storage temperature control material provided by the present invention has the three-dimensional dispersion effect, and can form network constraints on other phase change materials and strengthen the mechanical properties of the material, such that the shape of the material is fixed, and a liquid phase-crystal phase separation phenomenon in the phase change process is avoided; and the organic synthetic fiber-based phase-change material is a porous fiber and can load a nucleating agent, such that the nucleating agent is uniformly distributed in the phase-change material, thereby inducing the formation of a crystal nucleus in the crystallization process, and thus, the occurrence of a supercooling phenomenon can be avoided, and the heat absorption and release efficiency can be improved; and a phase-change energy-storage agent can absorb and release heat by means of solid phase-liquid phase transition of the material, such that the temperature control effect is achieved, a phase-change temperature regulator can regulate the phase-change temperature range of the phase-change material, and thus, the energy-storage temperature control material is suitable for climate characteristics of northern areas in China.
