Description

technical field [0001] The invention relates to the field of heat storage, in particular to a preparation method of a heat storage material. Background technique [0002] With the rapid consumption of fossil fuel resources and the continuous growth of global energy demand, the energy crisis is becoming more and more serious, and thermal energy storage is an effective way to recycle heat energy and improve energy utilization efficiency. Latent heat storage materials are usually called phase change materials, which absorb or release a large amount of energy during the phase transition process, and release heat when the environment needs it, so as to effectively control the ambient temperature, with high latent heat and good thermal stability. It has good application prospects in the field of energy storage technology. [0003] Organic phase change materials mainly include paraffin, ester, polyol, fatty acid and high molecular polymer, etc. Among them, paraffin has the advanta...
