The invention belongs to the technical field of recycled plastic applications, and provides a method for recycling recycled plastics for cable sheath materials. In the method, after melting, recycled plastics are treated with plasma to homogenize molecular chains, reduce viscosity, increase free volume and enhance molecular chain mobility. Then, the plastics are blended with rubber under high pressure with the assistance of a crosslinking agent and a catalyst, so that freely movable activated recycled plastic molecular chains crosslink with rubber and self-polymerize to form cable sheath materials with high strength, high elongation and high softness. Compared with traditional methods, it overcomes the defects of reduced strength and unstable quality of recycled plastics in conventional recycling. The obtained cable sheath materials have high strength, elongation and softness with excellent service properties. Meanwhile, the whole process is simple, easy to control, with relatively stable product quality, and can realize industrial production.
