Description

technical field [0001] The invention belongs to the field of polymer materials, and more specifically relates to a graphene oxide, tourmaline powder, polyamide 6 composite material and a preparation method thereof. Background technique [0002] Polyamide-6 fiber is a polycaprolactam fiber obtained by ring-opening polymerization and spinning of monomer caprolactam, also known as nylon 6 or nylon 6. It has the advantages of high mechanical strength, good toughness, wear resistance, and weak acid and alkali resistance. It is used in the fields of spinning and engineering plastics. However, with the acceleration of industrial modernization, traditional polyamide-6 can no longer meet people's needs, and multifunctional polyamide-6 fibers have become a development trend. [0003] At present, the main modification method is to modify the matrix resin containing polyamide-6, generally introducing glass fiber, nano-silica, carbon nanotubes, montmorillonite, mica, nano-silver, copper...
