Production device and process of in-situ polymerization colored graphene modified polyamide-6 slices

Abstract

The invention discloses a production device and process for in-situ polymerization colored graphene modified polyamide-6 slices. The production device comprises a raw material storage tank, a static mixer, a refined terephthalic acid preparation tank, a modifier preparation tank, a graphene preparation tank, a coloring agent preparation tank, a dynamic mixer and the like. According to the invention, graphene modified polyamide-6 colored slices are directly prepared by adopting an in-situ polymerization method, the prepared slices can be directly spun to obtain functional colored yarns required by customers, and due to the fact that the particle size of the coloring agent is nanoscale, the service cycle of a spinning assembly is prolonged, and the spinning assembly can be used for 3-6 months generally, so that the production cost of spinning can be greatly reduced; and after treated graphene is added, the polyamide colored slice has multiple functions of antibiosis, high strength, far infrared and the like.

Description

technical field [0001] The invention relates to the technical field of preparation of polyamide-6 slices, in particular to a production device and process for in-situ polymerized colored graphene modified polyamide-6 slices. Background technique [0002] Polyamide itself has excellent comprehensive properties such as superior electrical insulation performance, good alkali resistance, corrosion resistance, excellent mechanical properties, and easy molding and processing. At present, the dyed yarn manufactured at home and abroad is mainly obtained by blending polyamide chips with color masterbatch before spinning, and then spinning to obtain colored yarns, or using polyamide chips for spinning, and then dyeing and finishing in the subsequent process. be made of. However, the problems and shortcomings of these two traditional manufacturing methods are as follows: [0003] 1. The particle size of the colorant in the masterbatch is in the micron range, resulting in a short cycl...

AI Technical Summary

Problems solved by technology

[0003] 1. The particle size of the colorant in the masterbatch is micron level, resulting in a short cycle of the spinning assembly, poor spinnability, and easy spinning and breaking

[0004] 2. The blending uniformity of masterbatch is poor, and the spun silk has color difference

[0005] 3. The dyeing and finishing process requires a large amount of water and dyes, and discharges waste water with extremely high chemical oxygen demand, which is very polluting
