Charging wire material for electric vehicles and preparation method thereof

Abstract

The invention discloses a charging wire material for electric vehicles and a preparation method thereof. The charging wire material is prepared by the following steps: adding a plastic elastic soft material and white oil to a high-speed mixer and stirring so that the white oil is completely and uniformly absorbed; sequentially adding an activated halogen-free composite flame retardant, 0-20 parts of a charcoal forming agent, a smoke suppressor, an oxidant, a lubricant, a wear-resistant agent, a coupling agent and a bulking agent to the high-speed mixer and mixing; transferring mixed materials to a reactant twin-screw extruder hopper, and implementing melt-blending, extrusion and granulation at processing temperature of 150-250 DEG C to obtain a product. The fire-resistant wire composite material prepared by the invention has the advantages of being halogen-free, low in smoke, soft and easy to curl, wear resistant on surface, easy to process and form, and recyclable; the composite material can better meet using requirements of charging wire material for current electric vehicles.

Description

Technical field [0001] The invention relates to a charging wire material for electric vehicles and a preparation method thereof. Background technique [0002] In the past 30 years, the world economy has developed rapidly, and at the same time, the environmental protection problem facing mankind has become increasingly severe. In the global automotive industry, the pollution caused by automobile exhaust has attracted widespread attention. The research and development and promotion of new energy vehicles have received attention from many countries. Many developed country automobile manufacturers have successively launched electric vehicles of different brands and built them within their own countries. Vehicle charging stations meet the needs of the growing electric vehicle market. At present, most of the charging wire materials for electric vehicles still use halogen-containing PVC substrates as their wire sheath materials. Although this kind of charging wire has good insulation, ...

AI Technical Summary

Problems solved by technology

At present, most of the charging wire materials for electric vehicles still use halogen-containing PVC base material as the wire sheath material. Toxic hydrogen chloride gas has a greater fire hazard, which poses a great potential threat to many electric vehicle users during use

At present, although many other materials have been developed for electric vehicle charging wire materials, such as polyolefin cross-linked materials, vulcanized rubber materials, elastomer materials, etc. , surface wear resistance, easy processing and molding, recyclable, etc.
