Problems solved by technology

[0003] At present, the automotive cables that require a relatively high temperature resistance of 125°C in the market are mainly irradiated cross-linked polyethylene and thermoplastic polypropylene, but the price of irradiated cross-linked polyethylene and thermoplastic polypropylene cable materials is high and the extrusion speed is high. Slow, complex process, low yield rate, especially cross-linked irradiated polyethylene needs to be applied after being made into wires and then irradiated. PVC cable materials have the advantages of wear resistance, light texture, easy processing, and high cost performance. It has been widely used in the automotive field, and the PVC automotive cable material that meets the high temperature of 125°C in the automotive industry has a huge market potential to replace cross-linked polyethylene and thermoplastic polypropylene.

[0004] Patent CN103788531A uses PVC resin, special plasticizers, stabilizers, lubricants and fillers to prepare PVC cable materials with a temperature resistance of 125°C. The stabilizers are mainly selected from ordinary commercially available calcium-zinc stabilizers, and the fillers are selected from 2000 Ultrafine fillers above mesh, calcium-zinc and organotin stabilizers have a relatively high thermal stability effect on PVC, but the simple use of calcium-zinc stabilizers requires a relatively high addition amount to achieve a better stabilization effect , it is easy to cause low physical properties of PVC cable materials and easy to produce pitting, which affects the appearance and performance of cable materials. Therefore, a low-addition special stabilizer is used to develop a cost-effective and environmentally-friendly 125°C-resistant car. Cable material is very necessary
