Abstract

The invention provides a discontinuous shielding tape and a preparation method thereof. The discontinuous shielding tape comprises a metal layer, a first polyester film layer and a second polyester film layer which are arranged sequentially from top to bottom, wherein the metal layer is provided with a first notch and a second notch; and the first notch and the second notch have different slit widths. The discontinuous shielding tape has a metal / film / film structure, and in comparison with the conventional discontinuous shielding tape with a metal / film structure, the damage of the laser energyto the film can be reduced in the case of metal cutting by the laser, the stretching performance of the shielding tape is improved, and as the first notch and the second notch with different slit widths are arranged, one-time processing is achieved, the diversity of discontinuous shielding tapes is enhanced, and signal crosstalk is reduced.

Description

technical field

[0001] The invention belongs to the technical field of shielding tape processing, and relates to a discontinuous shielding tape and a preparation method thereof. Background technique

[0002] Shielding tape is mainly used in wires and cables to play a shielding role and ensure signal transmission. The shielding tapes used by existing wires and cables on the market are usually composed of polyester film layers and aluminum foil layers. With this structural design, the static electricity on the surface accumulates relatively large. To reduce signal crosstalk, non-continuous shielding tape is widely used because it reduces charge buildup on shielded elements. Compared with conventional continuous shielding tape, discontinuous shielding tape eliminates the need for shield grounding, reduces the cost of installing shielded cables, and has unique advantages in the market.

[0003] The structure of conventional discontinuous shielding tape is shielding unit / polyes...
