The invention discloses a paraffin/iron tailing ceramic composite phase change energy storage material and a melt and infiltration preparation method thereof. The composite material is prepared from the following raw materials in percentage by volume: 70 to 85 percent of paraffin and the balance of iron tailings. The composite phase change energy storage material provided by the invention has the advantages of high solid waste utilization rate, high phase change material content, high energy storage density, good mechanical property, low cost and the like; after large-scale application, the peak load shifting of energy sources can be realized; the pressure of the iron tailings on ecological environment is relieved; meanwhile, the heat conduction performance and the energy storage efficiency of the phase change material are effectively improved. The invention also discloses a melt and infiltration preparation method of the paraffin/iron tailing ceramic composite phase change energy storage material. The proces
