High-fire-resistant cable for electric automobile trim

Abstract

The invention relates to a cable, in particular to a high-flame-retardant cable for an electric automobile trim. The cable comprises a copper conducting wire and an insulation layer, wherein the insulation layer is a low-smoke halogen-free flame-retardant irradiation crosslinking polyolefin layer with a high oxygen index; the low-smoke halogen-free flame-retardant irradiation crosslinking polyolefin layer is prepared from the following materials in parts by weight: 50.3 parts of polyolefin resin, 45 parts of fire retardants, 1.5 parts of cross-linking agents, 2 parts of smoke suppressors, 0.2 part of antioxidants and 1 part of processing auxiliary agents. The copper conducting wire uses 6 kinds of soft conductor single copper wires conforming to the requirements of GB / T 3956. The high- flame-retardant cable for the electric automobile trim. provided by the invention. has the advantages that the flame-retardant performance is high; the mechanical performance is good; no halogen is contained; the use is safe; the environment-friendly effect is achieved; after combustion, no halogen acid gas is generated; the smoke amount of the cable is reduced; the safety factor is high; in addition, the weight is light; the cost is reduced.

Description

technical field [0001] The invention relates to a cable, in particular to a cable for interior decoration of high flame-retardant electric vehicles. Background technique [0002] At present, PVC material cables are widely used in electric vehicle interior cables at home and abroad. PVC material cables have disadvantages such as unenvironmental protection, toxicity (containing halogen), high material density, poor mechanical properties, easy cracking, inconspicuous liquid resistance, poor flame retardancy, and high density of combustion smoke. The material is not environmentally friendly, toxic, and unsafe for the environment and the human body; the density of the material is high, which increases the weight of the vehicle. The mechanical properties directly affect the quality and service life of the cable. The composition of the PVC material directly determines that once the wire is caught on fire, it will produce toxic gas and a large amount of smoke. Contents of the inv...
