The invention relates to the technical field of materials, in particular to a phase change energy storage material and a preparation method and application thereof. A phase change energy storage material is prepared from raw materials including a foaming carrier and paraffin; the preparation raw materials of the foaming carrier comprise the following components in parts by weight: 100-150 parts of base material, 10-40 parts of foaming agent, 5-30 parts of modifier, 1-8 parts of lubricant, 1-10 parts of nucleating agent and 1-5 parts of other auxiliary agent. The invention provides a phase change energy storage material, which is characterized in that a self-made high-performance porous foaming carrier is used for adsorbing phase change substance paraffin which is heated to be above a melting point, and the adsorption amount of the paraffin is higher and can reach 70%; the phase change energy storage material provided by the invention shows solid-solid phase change characteristics in the phase change process, and has the advantages of high phase change enthalpy, moderate phase change temperature and wide application range. |
