Shell, electronic equipment and shell preparation method

The invention relates to the technical field of anti-corrosion surface treatment, and discloses a shell, electronic equipment and a shell preparation method.The shell is applied to the electronic equipment and comprises a metal base material, a metal oxide film layer is arranged on the surface of the metal base material, and an organic film layer is arranged on the surface, away from the metal base material, of the metal oxide film layer; a silicon dioxide inorganic hydrophobic film layer is arranged on one side, deviating from the metal base material, of the organic film layer; wherein silicon dioxide net structures in the organic film layer and the silicon dioxide inorganic hydrophobic film layer are crosslinked through a silane coupling agent. The silicon dioxide inorganic hydrophobic film layer is combined on the surface of the organic film layer, so that corrosive substances can be prevented from intruding into a metal substrate, an anti-corrosion effect is achieved, and the adhesive capacity of corrosiv
