Problems solved by technology

The cable material uses a polar resin with poor compatibility with the base material as an oil resistance modifier. Although a compatibilizer is added at the same time, the tear resistance and heat resistance of the material are poor
Chinese patent application CN201410829392.2 discloses a halogen-free flame-retardant cable material for electric vehicle charging cables and a preparation method thereof. The cable material includes an elastomer resin, a flame retardant and a flame-retardant synergist, wherein the elastomer resin is thermoplastic polyurethane Elastomer, the flame retardant is a blend of melamine urate and melamine phosphate, and the flame retardant synergist is hypophosphite. Specifically, the cable material contains: 95-100 parts of elastomer resin, flame retardant 10-40 parts, 0.5-3 parts of flame retardant synergist, 5-20 parts of plasticizer, 0.5-3 parts of composite antioxidant, 0.5-3 parts of anti-ultraviolet agent, 0.5-3 parts of light shielding agent, processing aid The cable material uses polyurethane elastomer as the base material. Although it has the advantages of high strength, heat resistance, aging resistance, and oil resistance, it has insufficient tear resistance, is not easy to process, and has a high cost.
