Embodiment 1

[0029] like figure 1 As shown, a heat-dissipating electromagnetic shielding wave-absorbing tape includes a release film 40, and also includes a wave-absorbing material 10, a copper foil 20, and a heat-dissipating material; the copper foil 20 is arranged above the wave-absorbing material 10, and the A pressure-sensitive adhesive 50 is arranged between the copper foil 20 and the wave-absorbing material 10; the heat dissipation material is arranged above the copper foil 20; the release film 40 is arranged under the wave-absorbing material 10 On the surface, several layers of PET double-sided adhesive tape 60 are arranged between the release film 40 and the wave-absorbing material 10 .

[0030] The wave-absorbing material 10 is a ferrite film, and the ferrite film is a casting sheet of one or two of carbonyl iron powder, sendust powder, and Mn—Zn ferrite.

[0031] The heat dissipation material is heat dissipation coating 30 .

[0032] When the heat dissipation material is a heat...

Embodiment 2

[0037] like figure 2 As shown, a heat-dissipating electromagnetic shielding wave-absorbing tape includes a release film 40, and also includes a wave-absorbing material 10, a copper foil 20, and a heat-dissipating material; the copper foil 20 is arranged above the wave-absorbing material 10, and the A pressure-sensitive adhesive 50 is arranged between the copper foil 20 and the wave-absorbing material 10; the heat dissipation material is arranged above the copper foil 20; the release film 40 is arranged under the wave-absorbing material 10 On the surface, several layers of PET double-sided adhesive tape 60 are arranged between the release film 40 and the wave-absorbing material 10 .

[0038] The wave-absorbing material 10 is a ferrite film, and the ferrite film is a casting sheet of one or two of carbonyl iron powder, sendust powder, and Mn—Zn ferrite.

[0039] The difference from Embodiment 2 is that when the heat dissipation material is a graphite sheet 30a, the graphite sh...

Abstract

The invention relates to the field of adhesive tapes, and in particular, relates to a heat dissipation type electromagnetic shielding wave-absorbing adhesive tape which comprises a release film, a wave-absorbing material, a copper foil and a heat dissipation material; the copper foil is arranged above the wave-absorbing material, and a pressure-sensitive adhesive is arranged between the copper foil and the wave-absorbing material; the heat dissipation material is arranged above the copper foil; the release film is arranged on the lower surface of the wave-absorbing material, and a plurality oflayers of PET double faced adhesive tapes are arranged between the release film and the wave-absorbing material. The wave-absorbing material is used as a base material and is compounded with the copper foil, the heat dissipation material is treated on the surface of the copper foil, and the ultrathin acrylic pressure-sensitive adhesive is compounded on one surface of the wave-absorbing material,so that the heat dissipation type electromagnetic shielding wave-absorbing adhesive tape is simple in structure, good in heat dissipation effect, good in electromagnetic shielding effect, high in wave-absorbing capacity and convenient to use.

Description

technical field [0001] The invention relates to the field of adhesive tapes, in particular to a heat dissipation type electromagnetic shielding wave-absorbing adhesive tape. Background technique [0002] Tape is one of the tools commonly used for fixing and covering in daily life and work. According to its function, it can be divided into high-temperature tape, PET double-sided tape, conductive tape, shading tape, pressure-sensitive tape, die-cut tape, shielding tape, etc. [0003] The existing adhesive tape has a single function and is applied to electronic products. Due to poor electromagnetic shielding ability and weak heat dissipation performance, electronic products are more likely to be interfered or malfunction, which affects the use of electronic products. In view of the above technical problems, it is necessary to provide a new adhesive tape to better solve the above technical problems. Contents of the invention [0004] In order to solve the above technical prob...
