Abstract

The embodiment of the invention discloses an electromagnetic shielding membrane, which relates to the field of wire material manufacturing and is used to solve the problems that the existing electromagnetic shielding membrane is easy to break and the preparation process consumes a lot of time and electric energy. The electromagnetic shielding film body for cables of the present invention includes a first metal layer, a conductive layer and a protective film; the first metal layer is covered on the outer cover of the conductor of the cable, and is used for shielding electromagnetic interference and as a medium; the conductive layer It is arranged on the first metal layer for shielding electromagnetic interference, and the conductive layer includes a curing agent, metal particles and polyurethane for carrying metal particles; the protective film is arranged on the conductive layer for protecting the electromagnetic shielding film body, The first metal layer is a metal film composed of at least one of gold, silver, copper, nickel and aluminum, or an alloy film of at least two of gold, silver, copper, nickel and aluminum, so that the first The metal layer shields electromagnetic interference and acts as a conductive medium at the same time.

Description

technical field [0001] The invention relates to the field of wire material manufacturing, in particular to an electromagnetic shielding film body. 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, it is nece...
