| titleOfInvention | Mineral coupling-based composite phase-change heat storage material and preparation method thereof |
| abstract | The invention discloses a mineral coupling base composite phase change heat storage material and a preparation method thereof, in particular to a crystalline flake graphite-carbon nanofiber-bentonite base composite phase change heat storage material and a preparation method thereof; belonging to the technical field of heat storage material preparation. Growing Carbon Nanofibers (CNF) on a crystalline flake graphite substrate by a chemical vapor deposition method, carrying out condensation reaction with modified bentonite to obtain a crystalline flake graphite-CNF-bentonite substrate material, and then loading stearic acid to prepare a composite phase-change heat storage material; the heat storage performance of the composite phase-change heat storage material is synergistically improved by coupling the CNF with the crystalline flake graphite and the bentonite; the composite phase-change heat storage material comprises stearic acid and a scale graphite-CNF-bentonite matrix material in a mass ratio of 3-9:1-7, wherein in the scale graphite-CNF-bentonite matrix material, the mass ratio of the scale graphite-CNF to the bentonite is 1-5: 1-5. The heat storage material designed by the invention has the characteristics of large heat storage capacity, high heat absorption and release rate and the like. |
