1. A composite phase change material, comprising:
65 to 80 parts of a phase change material by weight; and
20 to 35 parts of a binder by weight;
wherein,
the binder comprises an acrylate monomer having a molecular weight of 50 to 300, an acrylate polymer having a molecular weight of 500 to 2000, and an initiator; and
the phase change material has a core-shell structure, comprising a shell and a core wrapped in the shell; the shell being a mixture of polyphenoloxy resin and polyethylene glycol; and the core being modified paraffin wax; wherein a molecular weight of the polyphenoloxy resin is 30000 to 60000, a molecular weight of the polyethylene glycol is 4000 to 12000; and the polyphenoloxy resin and the polyethylene glycol are mixed in a mass ratio of 1:7 to 1:3.
