| titleOfInvention | A kind of phase change energy storage material and preparation method thereof |
| abstract | The invention discloses a phase-change energy storage material and a preparation method thereof. The phase change energy storage material of the present invention comprises the following components in parts by mass: hydrated aluminum sulfate: 50 to 65 parts; erythritol: 35 to 50 parts; expanded graphite: 5 to 20 parts; hydrated aluminum sulfate A total of 100 parts of salt and erythritol. The preparation method of the phase change energy storage material of the present invention comprises the following steps: 1) mixing hydrated aluminum sulfate and erythritol and heating to complete melting to obtain a molten mixture; 2) adding expanded graphite to the molten mixture and mixing , that is, the phase change energy storage material is obtained. The phase-change energy storage material of the invention has the advantages of high phase-change enthalpy, low degree of subcooling, no phase separation, high thermal conductivity, etc., low cost, green and safe raw materials, mild preparation conditions, simple operation, and can be used for cleaning Heating, industrial waste heat recovery and solar thermal conversion and other fields. |
