Abstract

The invention provides a shielding film, a preparation method of the shielding film and a cable. The production efficiency of the cable can be improved while the shielding rate of the cable is improved. The shielding film comprises a carrier layer, a first shielding layer and a second shielding layer, wherein the carrier layer comprises a target carrier as well as metal particles and carbon particles which are filled into the target carrier and is used for shielding electromagnetic interference; the first shielding layer and the second shielding layer are both attached to the carrier layer, and the first shielding layer and the second shielding layer are symmetrically arranged relative to the carrier layer; the first shielding layer and the second shielding layer are composed of the metalparticles and the carbon particles and used for shielding electromagnetic interference and strengthening the target carrier.

Description

technical field [0001] The present application relates to the field of cables, in particular to a shielding film, a preparation method of the shielding film and a cable. Background technique [0002] With the high development of the information industry, cables have also achieved considerable development, and shielding electromagnetic interference is the key to the development of cables. [0003] At present, for wires and cables that require a high shielding rate, multiple production process coordination is required, which seriously affects production efficiency and increases a large amount of investment in equipment and manpower; Requirements, such as the current USB 3.1C TYPE signal transmission line, it needs to solve the complex electromagnetic interference problem generated during high-speed transmission, which cannot be effectively solved by traditional technology (mylar aluminum foil coating + braided mesh), which affects the development of cables.
