Problems solved by technology

CN103709741A discloses a carbon nanotube / nylon 6 composite material and a preparation method thereof, the carbon nanotube / nylon 6 composite material includes modified carbon nanotubes and nylon 6, wherein the modified carbon nanotubes are surface-modified carbon Although nanotubes and modified carbon nanotubes can improve the comprehensive performance of materials, the preparation is complicated and the operation is troublesome. Although the compatibility of carbon nanotubes in PA is improved, there are still a small amount of agglomerated carbon nanotubes that make the waste filament rate Therefore, there is a need for a modified nylon material that can increase the strength of nylon fibers without affecting fiber spinning

Abstract

The invention provides modified nylon fiber master batches and a modified nylon fiber prepared by using the same. The modified nylon fiber master batches are prepared from the following raw materialsin parts by weight: 90-99.9 parts of nylon 6 slices, 0.1-8 parts of zirconium phosphate nano-sheets, 0.01-1 part of carbon nano-tubes and 0.03-3 parts of ionic liquid. In the modified nylon fiber master batches provided by the invention, the zirconium phosphate nano-sheets and the carbon nano-tubes are adhered to the surfaces of the nylon 6 slices through the added ionic liquid, so that agglomeration of the zirconium phosphate nano-sheets and the carbon nano-tubes is prevented, and the dispersion uniformity of the zirconium phosphate nano-sheets and the carbon nano-tubes in the modified nylonfiber master batches is improved.

Description

technical field [0001] The invention belongs to the field of modified fibers, and relates to a modified nylon fiber masterbatch and modified nylon fibers prepared by using the same. Background technique [0002] Nylon fiber is currently one of the most widely used synthetic chemical fibers in production and life. It has excellent mechanical properties and electrical properties, and also has the advantages of wear resistance, oil resistance, self-lubrication, corrosion resistance and good processing performance. It is widely used It is used in various textiles, tire cords, cables, etc., but PA has high water absorption, low temperature and poor dry impact toughness, so its application range is limited. In order to meet the special requirements of different fields, PA needs to be modified. Modification, how to further improve the strength and processing performance of nylon fibers has always been a topic of great concern to both academic and industrial circles. CN102850784A d...
