Problems solved by technology

However, in this method, graphene is unevenly dispersed in the spinning solution, resulting in unevenly dispersed graphene in the obtained textiles, and the effect of graphene cannot be brought into full play.
In addition, in the process of preparing colored textiles, the pigments are very easy to cover graphene, resulting in the graphene in the obtained textiles being completely covered by pigments and unable to exert its efficacy.

Abstract

The invention relates to graphene modified color paste. The graphene modified color paste is prepared from, by weight, 0.1-5% of graphene, 15-55% of carbon black, 2-25% of functional aids, 2-20% of a dispersing agent and the balance a solvent. By adding the specific amount of graphene into the color paste containing the specific amount of carbon black, the carbon block is attached to the surface of the graphene, dispersion of graphene can be facilitated because of the binding force between the carbon black and the graphene, and the defect that the graphene is not uniform in dispersion after being added into spinning liquid. Besides, the binding force between the specific amount of graphene and the specific amount of carbon black disappears in the spinning process, the functions of graphene in obtained textiles are give play to, and the textiles have the characteristics, such as excellent far infrared performance, bacteria resistance and the bacteriostasis and ultraviolet resistance, of graphene.

Description

technical field [0001] The invention belongs to the technical field of dyes and relates to a color paste, in particular to a graphene-modified color paste, a preparation method and an application thereof. Background technique [0002] Graphene is SP between carbon atoms 2 It is a monoatomic layer planar crystal that is hybridized into bonds and arranged into a two-dimensional honeycomb lattice, which has a large specific surface area and excellent electrical, thermal and mechanical properties. Currently, the most attractive property of graphene for researchers is its excellent mechanical properties. Graphene is the strongest substance known to man, harder than diamond and 100 times stronger than the best steel in the world. The use of graphene and matrix polymers to prepare composite materials or fibers can significantly improve the performance of materials, such as improving physical and mechanical properties, improving electrical and heat resistance properties, etc. [...
