Problems solved by technology

However, the disadvantage of these conductive fillers is that the large amount of addition leads to a decrease in the mechanical properties of the material, or the use of in-situ polymerization, solution compounding and other operations is complicated, consumes a large amount of solvent, and is not suitable for large-scale production.
It has not been reported to prepare a high-strength antistatic composite material for automobiles on the basis of simple operation and easy industrial production.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, and in particular relates to an antistatic material, a preparation method and an application thereof. Background technique [0002] Polymer materials generally have the advantages of easy processing and molding, but their applications are usually limited for insulating materials. People usually use carbon such as carbon black, graphite, carbon fiber and carbon nanotubes as conductive materials to prepare various conductive materials. However, the disadvantage of these conductive fillers is that the large amount of addition leads to a decrease in the mechanical properties of the material, or the use of in-situ polymerization, solution compounding and other complicated operation steps consumes a lot of solvents and is not suitable for large-scale production. The preparation of a high-strength antistatic composite material for automobiles on the basis of simple operation and eas...
