ENERGY-STORING TEMPERATURE CONTROL MATERIAL AND PREPARATION METHOD AND APPLICATION THEREOF

The present invention provides an energy-storing temperature control material, and belongs to the technical field of temperature control materials. In the energy-storing temperature control material provided in the present invention, the organic synthetic fiber based phase-change material has a three-dimensional dispersion effect, and can form a network constraint for remaining phase-change materials to reinforce mechanical properties of the materials, thereby fixing shapes of the materials and avoiding a liquid-crystal phase separation phenomenon in the phase-change process. The phase-change energy storage agent can absorb and release the heat by means of solid-liquid phase conversion of the material, to achieve the temperature control effect; and the phase-change temperature regulator can regulate a phase-change temperature range of the phase-change material, to make the energy-storing temperature control material suitable for climatic features of northern China.
