The invention discloses a wire and cable with corrosion-resistant function and a preparation method thereof, and relates to the technical field of cables. The wire and cable comprises a metal inner core, an outer skin wrapped with the metal inner core, and a protective adhesive layer applied on the surface of the outer skin. The sizing material comprises 30 to 40 parts of polyvinyl chloride resin, 25 to 35 parts of polyurethane, 15 to 25 parts of 1,3-butadiene, 5 to 15 parts of modified alumina powder, 1 parts to 3 parts of stearic acid, 1 part to 2 parts of dioctyl phthalate, 5 parts to 15 parts of nano-silicon dioxide and 5 to 10 parts of acrylonitrile, and the protective adhesive layer comprises an outer skin adhesive materials, 2 to 5 parts of powder, 1 to 3 parts of mixed materials, the use of the combination of the outer skin rubber material and the protective rubber layer can effectively enhance the corrosion resistance of the cable, reduce the annual corrosion depth of the cable, and reduce the occurrence of corrosion spots. Exist, enhance the tensile strength of the cable, thereby prolonging the service life of the cable. |
