Abstract

Embodiments of the invention disclose an electromagnetic shielding film for a cable, relates to the wire rod manufacturing field, and is used to solve the problems of easy fractures of an existing electromagnetic shielding film and large time and electric energy consumption in the preparation process. The electromagnetic shielding film for the cable comprises a first metal layer, a conductive layer and a protection film; the first metal layer covers ecderon of a conductor of the cable, and is used for shielding an electromagnetic interference and being taken as a medium; the conductive layer is disposed on the first metal layer and is used for shielding the electromagnetic interference, and the conductive layer comprises a curing agent, metal particles and polyurethane for bearing the metal particles; and the protection film is disposed on the conductive layer, and is used for providing protection for the electromagnetic shielding film.

Description

technical field [0001] The invention relates to the field of wire material manufacturing, in particular to an electromagnetic shielding film used for cables. Background technique [0002] In the cable production industry with signal transmission and / or power transmission, in order to reduce impedance, attenuation, prevent signal interference and prevent loss during internal transmission, electromagnetic shielding is usually added to the wire for electromagnetic shielding. A common practice is to cover the conductor layer by layer with at least two layers or shielding materials and at least two processing steps, that is, after the conductor is formed and the outer surface of the conductor is covered with a jacket, it is first necessary to wrap the conductor. Cover a layer of Mylar aluminum foil, and then carry out a metal braiding layer on the Mylar aluminum foil. Due to the mesh in the braid, according to the requirements of the electromagnetic shielding effect of the cable,...
