High-molecular polymer material for wires and cables and preparation method of the high-molecular polymer material

The invention relates to a high-molecular polymer material for wires and cables and a preparation method of the high-molecular polymer material. The polymer material comprises nanometer titanium dioxide, 4,4'-diaminodiphenyl disulfide, a modifying agent, an antioxidant 1010 and polyethylene wax. The mass ratio of the nanometer titanium dioxide, the 4,4'-diaminodiphenyl disulfide, the modifying agent, the antioxidant 1010 and the polyethylene wax. is (5-10): (5-10): (5-10): (0.3-0.5): (1-2). The product provided by the invention can realize self-repairability at room temperature, and the repairing effect reaches 100% or above within 24 hours. The product provided by the invention can be used as a sheath material for manufacturing and production of cable products, and after the sheath material is damaged, the polymer material can be automatically repaired and healed after a period of time, so that the tedious process of manual repair after the sheath is damaged is changed, and the production efficiency of the c
