Embodiment 1

[0026] A kind of preparation method of multi-color graphene antibacterial liquid, it is characterized in that, preparation process is as follows:

[0027] S01. Weigh the graphene material and surfactant in proportion and add them into deionized water in sequence, and ultrasonically disperse them uniformly to prepare a graphene material solution, wherein the composition of each component by weight percentage is: graphene 5%, surfactant Sodium Lauryl Sulfate 0.2%. During the preparation process, the temperature was controlled at 50°C;

[0028] S02. Weigh dyes, dispersants and defoamers in proportion and add them in sequence to the graphene material solution prepared in step S01, and ultrasonically disperse evenly. The composition of each component by weight percentage is: dye 0%, disperse Agent 0%, antifoaming agent polydimethylsiloxane 0.1%. When the solution is completely uniformly dispersed, the antibacterial liquid is obtained.

[0029] In order to further describe the fi...

Embodiment 2

[0033] This comparative example provides a kind of polychromatic graphene antibacterial liquid, differs from embodiment 1 in that:

[0034] S02. Weigh dyes, dispersants and defoamers in proportion and add them in sequence to the graphene material solution prepared in step S01, and ultrasonically disperse evenly, wherein the composition of each component by weight percentage is: dye food coloring beet red 8%, 0.04% sodium methylene bismethyl naphthalene sulfonate dispersant, 0.1% polydimethylsiloxane defoamer. When the solution is completely uniformly dispersed, the antibacterial liquid is obtained.

[0035]In order to further describe the field of application of the antibacterial liquid, this embodiment uses the antibacterial liquid in the field of textiles to obtain antibacterial cotton prepared by using the antibacterial liquid. In order to ensure that the different parameters lead to the difference between the prepared antibacterial cotton and Example 1, the same operation...

Embodiment 3

[0037] A kind of preparation method of multi-color graphene antibacterial liquid, it is characterized in that, preparation process is as follows:

[0038] S01. Weigh the graphene material in proportion, and add the surfactant in deionized water in sequence, and ultrasonically disperse evenly to prepare a graphene material solution, wherein the composition of each component by weight percentage is: graphene oxide 3%, surface active Sodium dodecylbenzenesulfonate 0.1%. During the preparation process, the temperature was controlled at 25°C;

[0039] S02. Weigh dyes, dispersants and defoamers in proportion and add them in the graphene material solution prepared in the step S01 in sequence, and ultrasonically disperse evenly, wherein the composition of each component by weight percentage is: dye reactive yellow dye 5 %, dispersant sodium polyacrylate 0.08%, polyether modified silicon defoamer 0.5%. When the solution is completely uniformly dispersed, the antibacterial liquid is o...

Abstract

The invention provides a multicolor graphene antibacterial liquid, and a preparation method and an application thereof. The multicolor graphene antibacterial liquid provided by the invention selects agraphene material with excellent antibacterial performance and no drug resistance as a main antibacterial component of the antibacterial liquid. According to the preparation method of the multicolorgraphene antibacterial liquid, the multicolor graphene antibacterial liquid is obtained by gradually adding the graphene material, dye, various assistants and water according to the corresponding proportion in an ultrasonic dispersion mode. The preparation method is simple in process, easy to operate, free of excessive special reaction conditions, low in raw material cost, easy to obtain and environmentally friendly, can be directly applied to large-scale batch production and can be directly applied to different fields. The product prepared in the application field is bright and adjustable incolor and stable in coloring performance, has long-acting antibacterial performance before and after the dye is added, and still has efficient antibacterial performance after being placed for a long time or washed with water multiple times.
