Radiation heat dissipation mobile phone shell and preparation method thereof

The invention relates to the technical field of thermal management of electronic equipment, in particular to a radiation heat dissipation mobile phone shell and a preparation method thereof.The radiation heat dissipation mobile phone shell is made of a radiation cooling material, and the radiation cooling material is prepared from a polydimethylsiloxane precursor, a cross-linking agent and hexagonal boron nitride; the mass ratio of the polydimethylsiloxane precursor to the cross-linking agent is 10: (1-3), and the volume ratio of the polydimethylsiloxane precursor to the hexagonal boron nitride is 10: (1-6). The reflectivity of the radiation cooling material in a visible light wave band is greater than 98%, and the emissivity in an atmospheric window wave band is greater than 90%. The mobile phone shell body adopts an injection molding and thermocuring process, a mold is designed according to the model of a mobile phone, raw materials of a radiation cooling material are mixed in proportion and then injected i
