  • Patent number: 12098320
    Abstract: A heat storage composite material comprises components by weight: 30-55 parts of organic phase change material, 30-40 parts of two-dimensional thermally conductive carbon material, 10-20 parts of lamellar structure graphite, and 0-10 parts of oil-absorbing organic resin. A preparing method include steps of stirring the organic phase change material to disperse on a surface of the two-dimensional thermally conductive carbon material, and melting them so the organic phase-change material is adsorbed in gaps of the two-dimensional thermally conductive carbon material; stirring and mixing the lamellar structure graphite and the two-dimensional thermally conductive carbon material adsorbed with the organic phase change material in a mixer to obtain a mixed material; and placing the mixed material in a lamination mold for lamination treatment to obtain a sheet-shaped heat storage composite material. The heat storage composite material has high thermal conductivity and is not easy to leak.
