Abstract

The invention provides a cable material, and a preparation method and application thereof. The cable material is prepared from the following raw materials in parts by weight: 10-30 parts of polyethylene, 5-20 parts of silicone rubber, 5-15 parts of maleic anhydride graft EVA (ethylene-vinyl acetate), 0.5-10 parts of ethylene propylene diene monomer rubber, 40-65 parts of flame retardant, 2-5 parts of red phosphorus, 0.1-2 parts of silane coupling agent and 0.1-2 parts of triallyl isocyanurate. The preparation method comprises the following steps: banburying, extrusion and irradiation crosslinking. The cable material provided by the invention has the advantages of high flexibility, favorable insulativity, favorable flame retardancy, favorable oil resistance and favorable cold resistance, and is applicable to automobile wire insulating materials.

Description

technical field [0001] The invention belongs to the field of insulating materials, in particular to a cable material and a preparation method and application thereof. Background technique [0002] Wires and cables are one of the important parts of automobiles, and their reliability is crucial to driving safety. Due to various complex environments such as vibration, friction, ozone, oil pollution, high heat, cold and electromagnetic radiation inside the car, it is required that the car wires have various functions such as heat resistance, cold resistance, wear resistance, oil resistance and anti-interference. And as the functions of the car continue to change, the requirements for the car's wires are also increasing. [0003] The power system, control system and safety system of electric vehicles are all driven by electricity, and the internal cables will carry higher voltage and current than traditional automotive cables. The high current passing through the internal cable...
