Abstract
The invention belongs to the fields of research and development of new materials, and specifically relates to a cheap and high-quality mixed phase-change energy storage material and an preparation and an application thereof. The mixed phase-change energy storage material provided by the invention comprises the following raw materials in parts by weight: 55 to 58 parts by weight of 2,2-dimethyl-propanol, 25 to 30 parts by weight of borax, 2 to 4 parts by weight of a crosslinking agent and 2 to 6 parts by weight of a thickening agent. The mixed phase-change energy storage material provided by the invention realizes storage and release of energy through reversible solid-liquid phase transition, has a phase-change temperature of 40 to 60 DEG C, can reach a phase-change enthalpy of 240 J/g, and has the advantages of high energy storage density, good thermal stability, no liquid leakage and phase separation, simple preparation process, no toxicity, harmlessness, and good utilization value in the field of phase-change energy storage materials.
