Problems solved by technology

The cable sheath material prepared by the invention has a wide range of raw materials and a simple manufacturing process. The prepared cable sheath material has the characteristics of strong flexibility, high tensile strength, high elongation at break, and high flame-retardant strength, which can effectively prevent external force banding. The damage to the cable material caused by it improves the fire protection level of the cable in electrical engineering, and has broad application prospects; however, the strength and flame retardancy of the cable sheath material can still be further improved
