USE - Ultra-flexible high-efficiency radiating electromagnetic shielding adhesive tape used as adhesive tape of shielding cover for bonding electronic product parts. ADVANTAGE - The ultra-flexible high-efficiency radiating electromagnetic shielding adhesive tape has good light shielding, radiating, conductive, shielding performance, weather resistance, bending resistance and good reworking performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the method for manufacturing an ultra-flexible and high-efficiency heat-dissipating electromagnetic shielding tape is characterized by comprising the following steps: preparing a graphene fiber cloth, dissolving graphene oxide in N-methylpyrrolidone to obtain a graphene oxide dispersion liquid, and spinning the graphene oxide dispersion liquid The wire is extruded from the die head, and then immersed in a coagulation bath and coagulated into filaments. The solvent in the coagulation bath is a mixture of ethyl acetate and ethylene glycol, and is collected by a drying roller to obtain a graphene oxide ribbon with a wrinkled structure. Graphene oxide ribbons After twisting by a twisting device, a graphene fiber cloth is obtained after reduction; a conductive composite adhesive layer is coated on the conductive substrate, and is compounded with the graphene fiber cloth; the graphene heat dissipation layer is prepared, and the following components are mixed in proportion by weight: 100-150 pts. wt. polyurethane resin, 22-30 pts. wt. nano-graphene sheets, 5-10 pts. wt. filler particles, 50-80 pts. wt. first ink, 40-50 pts. wt. ethyl acetate, 5-8 pts. wt.polyisocyanate, and polymethyl 4-6 pts. wt. urea resin; the graphene heat dissipation layer is coated on the surface of the conductive substrate by gravure coating, and heated and dried. The back of the graphene fiber cloth is coated with a colored conductive adhesive layer.
