Embodiment 1-6

[0027] This embodiment provides a graphene printing paste and a preparation method thereof. The components and mass percentages of the graphene printing paste are shown in Table 1.

[0028] The preparation method of described graphene printing slurry is as follows:

[0029] Step 1: Disperse the prepared graphene powder in deionized water, prepare an aqueous solution with a concentration of 0.1-5 mg / ml, and add a dispersant in proportion. Then ultrasonicate it for 30min~60min to make it disperse evenly;

[0030] The graphene powder is prepared by one of a mechanical exfoliation method, a liquid phase exfoliation method, a chemical vapor deposition method, and a redox method;

[0031] The addition of the dispersant is 1% to 5% of the graphene powder; the dispersant is selected from polyvinyl alcohol, polyethylene glycol, sodium lignosulfonate, polyvinylpyrrolidone, hexadecane One or more of Trimethylammonium Bromide, Sodium Lauryl Sulfonate, Sodium Lauryl Sulfate.

Abstract

The invention provides a graphene printing paste and a preparation method thereof. The graphene printing paste is prepared from the following components in percentage by mass: 0.5% to 12% of graphenemicrocapsule, 0.1% to 5% of sodium alginate, 1% to 5% of thickener, 0.1% to 5% of dye, 0.5% to 3% of calcium carbonate, 0.01 to 0.05% of sodium hydroxymethyl cellulose, 0.1 to 0.5% of urea, and the balance of water. The graphene printing paste has the advantages that by adding the graphene microcapsule into the printing paste, and optimally proportioning with other components, the printing fabricwith exquisite patterns can be produced by the traditional printing technology; the obtained printed fabric has good permeability and firm coloring property, and the water fastness can reach grade 4 or above; the antibacterial property, anti-ultrasonic property and the like are excellent, the number of bacteria on clothes is greatly reduced, the anti-ultraviolet property of the fabric is improved,and the health of a human body is protected.

Description

technical field [0001] The invention relates to the technical field of textile auxiliaries, in particular to a graphene printing paste and a preparation method thereof. Background technique [0002] Printed fabrics are artistic products. According to the designed patterns, dyes or pigments are selected to print patterns on the textiles, so that the patterns are formed on the fabrics. There are three commonly used printing processes: direct printing, flooding printing and discharge printing. Direct printing is to directly print dyes or pigments on white or light-colored fabrics, and then obtain patterns through post-processing such as steaming. The process is short and the most widely used. Dyeing printing is to print on the fabric first to drive the dye to dye or develop color, and then dye or develop color, so as to obtain patterns on the dyed fabric. Discharge printing is a printing process that prints on dyed fabrics to eliminate dyed substances and obtain patterns on d...
