Abstract

The utility model discloses an easy-to-disassemble heat dissipation shielding wave absorbing adhesive tape, which comprises a graphite layer, a first high temperature resistant acrylic adhesive layer arranged on the upper end surface of the graphite layer, a ferrite layer arranged on the upper end surface of the first high temperature resistant acrylic adhesive layer, a second high temperature resistant acrylic adhesive layer arranged on the upper end surface of the ferrite layer, a foam layer arranged on the upper end surface of the second high temperature resistant acrylic adhesive layer, a third high temperature resistant acrylic adhesive layer arranged on the lower end surface of the graphite layer, a metal foil arranged on the lower end surface of the third high temperature resistant acrylic adhesive layer, and an electric viscosity reducing adhesive layer arranged on the lower end surface of the metal foil. The adhesive tape has the advantages that a passage can be formed between the adhered product and the metal foil layer when the adhesive tape is reworked, so that the viscosity of the electric anti-adhesive layer is reduced after current passes through the electric anti-adhesive layer, and the adhesive tape is torn off from the adhered object rapidly. When the whole adhesive tape protects the attached object, the adhesive tape has the functions of buffering, wave-absorbing shielding, heat dissipation and convenient disassembly.
