High-ductility cable material for electric vehicle charging system and preparation method thereof

Abstract

The invention relates to the technical field of cable materials, and discloses a high-ductility cable material for an electric vehicle charging system. The high-ductility cable material is prepared from the following raw materials in parts by weight: 50 to 100 parts of polyphenylene sulfide resin, 20 to 40 parts of polyethylene resin, 10 to 20 parts of brominated epoxy resin, 6 to 12 parts of talcpowder, 10 to 20 parts of glass fiber, 10 to 20 parts of carbon black, 20 to 30 parts of titanium dioxide, 5 to 15 parts of a flame retardant, 2 to 6 parts of a coupling agent, 1 to 2 parts of a copper inhibitor, 2 to 3 parts of an antioxidant and unavoidable impurities. According to the high-ductility cable material for the electric vehicle charging system the stability, the stability, tensile strength, shear strength, flexural strength and pressure strength of the cable material can be effectively enhanced by adding the talc powder and the glass fiber; the flame-retarding property of the cable material can be effectively improved by adding the carbon-containing flame retardant and a flame retardant made of a carbon compound, so that the service life of a cable is further prolonged.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a high ductility cable material for an electric vehicle charging system and a preparation method thereof. Background technique [0002] Electric vehicles are powered by vehicle-mounted power supplies, and use motors to drive wheels. Vehicles that meet the requirements of road traffic and safety regulations do not use traditional gasoline and diesel as fuel, and have less environmental impact than traditional vehicles. Their prospects are widely recognized. look good. [0003] As the application of electric vehicles becomes more and more widespread, the distribution area of ​​electric vehicle charging systems is also becoming wider and wider. Since the cables used in electric vehicle charging systems on the market are not very ductile, most of the cables used in electric vehicle charging systems It is placed on the charging pile of the electric vehicle charging system out...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a high ductility cable material for an electric vehicle charging system and a preparation method thereof, which has the advantage of high ductility and solves the problem of the cable ductility of the electric vehicle charging system currently on the market. It is very high, and most of the cables used in the electric vehicle charging system are placed on the charging piles of the outdoor electric vehicle charging system, which are often affected by various adverse environments such as wind, sun, rain, etc. , is often dragged, bent, and crushed, resulting in varying degrees of mechanical damage and shortening the service life of cables used in electric vehicle charging systems
