Insulation adhesive, insulation tape, and insulation adhesive preparation method

An electronic device, comprising:

• a camera module;
• and
• a housing assembly configured to protect the camera module, wherein the camera module is arranged on one side of the housing assembly, the housing assembly comprising:
• a rear housing and a camera bracket mounted on the rear housing, wherein there is a gap between the camera bracket and the rear housing, and
• the rear housing is connected to an insulation tape, the insulation tape is located between the rear housing and the camera module, and the insulation tape isolates the gap from the camera module, and
• wherein the insulation tape comprises:
• an insulation colloid and an insulation particle, and the insulation particle is doped in the insulation colloid, wherein breakdown field strength of the insulation particle is greater than breakdown field strength of the insulation colloid such that, under an electrostatic discharge (ESD), an electrostatic discharge current preferentially breaks down the insulation colloid and bypasses the insulation particle to lengthen a breakdown path, and the insulation particle is a highly electronegative non-polar insulation particle configured to suppress electron avalanche breakdown in a medium surrounding the insulation particle, and an electronegativity of the insulation particle is greater than an electronegativity of the insulation colloid.
