Film for absorption and shielding EMI and method for manufacturing the same, Cable having film for absorption and shielding EMI

摘要

The present invention is an electromagnetic wave absorbing and shielding film and its manufacturing method, employing the electromagnetic wave absorbing and shielding film relates to a wire and cable, and more particularly, the metal powder and the metal flakes and processed in the form of a plate, is composed of it and that the electromagnetic wave absorber layer paste or ink screen, the electromagnetic wave shielding layer attached to the electromagnetic wave absorbing layer relates to a wire and the electromagnetic wave absorption and shielding film and a method of manufacturing the same, and the electromagnetic waves generated to reduce the noise while absorbing and shielding etc. Communication cables, wires and cables employing an electromagnetic wave absorption and shielding film. ; for this end, the invention using an attrition mill which is movable at a constant speed with time, and the raw material of the spherical ball suspension of a metal alloy or a ceramic ball and the surfactant formulation was added to the plate processed with metal flake process; And in film production method for electromagnetic wave absorption and shielding comprises a drying step by washing the metal flake in ethyl alcohol or methyl alcohol or water, using a mixer, the metal flake powder and 30 to 95% by weight of resin: 70 - mixing and stirring at a rate of 5% by machining a metal paste process; The step of applying the metal paste on the shielding layer; And a shielding film for absorbing electromagnetic waves, characterized in that it comprises the production method, and the absorption and electromagnetic wave shielding film employing provides wires and cables ; electromagnetic wave, communication cable, radio frequency cables, power cables, control cables, absorption, pellet, sheet, noise, metal flake, resin
