NOVELTY - Preparing flexible cable comprises spraying polymer microsphere on the cable core, modifying the modified graphene oxide, N,N'-(4,4'-methylene diphenyl)bismaleimide, 1,3-butadiene and polyethylene into a sheath material, irradiating the sprayed cable core surface with a high pressure mercury lamp, coating the sheath on the surface of the irradiated cable core and rolling. USE - The method is useful for preparing flexible cable, which is used as an electric energy or signal transmission device, usually composed of many groups of wires. ADVANTAGE - The cable has excellent impact resistance, flame retardant and self-repairing performance.
