Abstract

The invention discloses a graphene oxide, sericite and polyamide 6 composite material and a preparation method thereof, belonging to the field of macromolecular materials. Specific to high requirementon the mechanical property of polyamide 6 industrial yarn, the invention discloses a composite material for preparing high-strength low-elongation polyamide fiber, and the preparation method comprises the following steps of dispersing graphene oxide in a ring opening agent solution by using ultrasound, cutting and emulsification integration technology, afterwards, enabling modified sericite and dispersion liquid thereof to be subjected to reaction, then dispersing by using the ultrasound, cutting and emulsification integration technology, and finally, performing mixed dispersion with liquid caprolactam to conduct in-situ polymerization modification. Fiber prepared from the polyamide 6 composite material not only has an excellent mechanical property but also has polyfunctionality.

Description

technical field [0001] The invention belongs to the field of polymer materials, and more specifically relates to a graphene oxide, sericite, 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, zinc, e...
