[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0020] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a composite conductive shielding electrical tape comprises a conductive adhesive layer 1 and a shielding layer 5, wherein a tensile layer 4 and a heat insulating layer 3 are sequentially arranged between the conductive adhesive layer 1 and the shielding layer 5 from top to bottom, an anti-corrosion layer 6 is arranged on the upper surface of the shielding layer 5, and a release film 2 is arranged on the upper surface of the anti-corrosion layer 6, Figure 1 After the tape is rolled up, the conductive adhesive layer 1 will be attached to the release film 2, so that the tape can be rolled up and stored conveniently.
[0021] The shielding layer 5 is made of copper foil, and the thickness of the shielding layer 5 is 20-45 um. The shielding layer 5 can achieve electromagnetic shielding effect, thereby preventing the outside world from generating electromagnetic interference to the material wrapped by the tape.
[0022] The conductive adhesive layer 1 is made of a base resin material, and the thickness of the conductive adhesive layer 1 is 10-25 um. The conductive adhesive layer 1 can be used to adhere materials and ensure that the adhered materials can be conductively connected.
[0023] Among them, the insulation layer 3 is made of glass fiber, and the thickness of the insulation layer 3 is 50-100um. The insulation layer 3 can reduce the heat conducted from the outside to the conductive adhesive layer 1, thereby increasing the service life of the conductive adhesive layer 1 and preventing the conductive adhesive layer 1 from falling off due to high temperature after the tape is pasted.
[0024] Among them, the tensile layer 4 is a grid structure, the tensile layer 4 is made of tensile fiber, and the thickness of the tensile layer 4 is 10-25um. The setting of the tensile layer 4 can improve the overall structural strength of the tape and avoid deformation of the tape during pulling.
[0025] The anti-corrosion layer 6 is an inorganic coating applied to the surface of the shielding layer 5. The thickness of the anti-corrosion layer 6 is 5 to 20 μm, which can effectively prevent the tape from being corroded after long-term use and improve the service life of the tape.
[0026] The utility model provides a composite conductive shielding electrical tape, the specific working principle of which is as follows:
[0027] The heat insulation layer 3 can isolate the heat conducted from the outer layer to the conductive adhesive layer 1, thereby increasing the service life of the conductive adhesive layer 1. The anti-tension layer 4 can improve the overall structural strength of the tape to prevent the tape from deforming during pulling. The inorganic coating on the surface of the shielding layer 5 can effectively prevent the tape from corroding after long-term use, thereby increasing the service life of the tape. The release film 2 located on the top layer can conveniently protect the conductive adhesive layer 1. Figure 1 When the tape is rolled up, the conductive adhesive layer 1 will adhere to the release film 2, thereby completely covering the conductive adhesive layer 1.
