Problems solved by technology

[0003] At present, in the domestic automotive cable market, most of the cable materials using PVC as the base material are halogen-containing flame-retardant or low-halogen flame-retardant. Although the price is low, the flame retardancy is good, and the processing performance is good, it does not meet the EU ROHS and With the promulgation of REACH environmental regulations and safety requirements, low-smoke halogen-free flame-retardant cable materials are the main development trend of automotive wire materials, and ordinary low-smoke halogen-free flame-retardant cable materials are difficult to meet the high wear resistance of automotive wire materials at the same time , high temperature resistance, oil resistance and special requirements for rapid extrusion

Description

technical field [0001] The invention relates to the field of automotive wire and cable materials, in particular to a high wear-resistant radiation cross-linked halogen-free flame retardant automotive wire and cable material and a preparation process thereof. Background technique [0002] Car wires are different from ordinary wires and cables. Because the inside of the car is a very complex small environment, there are various complex conditions such as vibration, friction, ozone, oil pollution, high heat, cold and electromagnetic radiation. Various functions such as wear resistance, oil resistance and anti-interference, and with the continuous change of automotive functions, the current automotive wires need to have higher high temperature resistance and high flame retardant properties to enhance the reliability and guarantee of automotive safety. [0003] At present, in the domestic automobile wire market, most of the halogen-containing flame retardant or low-halogen flame ...
