METHOD FOR PREPARING EMI SHIELDING FILM AND EMISHIELDING FILM PREPARED BY THE METHOD

摘要

The present invention relates to a method for producing an electromagnetic wave shielding film and a shielding film produced by the method. More particularly, the present invention relates to a method for producing an electromagnetic wave shielding film, And 40 to 55% by weight of a conductive powder; and a conductive layer forming step of forming a conductive layer on the first film and a conductive layer comprising a conductive layer containing 9 to 15% by weight of a binder, 1 to 5% by weight of a curing agent, % Of a filler and 40 to 55 wt% of a filler, and a lamination step of laminating the first film and the second film, wherein the binder is a polyester-modified At least one of urethane resin, synthetic epoxy resin, thermoplastic polyurethane (TPU) and polyurethane urea is selected.
