Embodiment 1

[0032] Embodiment 1 of the present invention discloses an ultrafine nano-liquid dispersion color paste, and the technical scheme adopted is as follows:

[0033] S1: Weigh 40g CI.B-79 Disperse Blue and dissolve it in 100mL carbon tetrachloride solvent to obtain a disperse dye solution;

[0034] S2: Then weigh 5g polyacrylate hyperdispersant and 1g silanol non-ionic wetting agent, dissolve in 100mL water, add grinding beads and stir and mix at a low speed of 100r / min for 10min to obtain a dispersed grinding system;

[0035] S3: Slowly add the prepared dye solution to the dispersion grinding system, grind and stir. After the disperse dye solution is added, gradually increase the stirring speed to 1000r / min, and at the same time increase the temperature and heat to 80°C, condense and reflux the organic solvent, and keep it Stir and grind for 5 hours, strip and recover the complete organic solvent to obtain a mixed dispersion system of disperse dyes, dispersants, wetting agents, water, an...

Embodiment 2

[0040] Embodiment 2 of the present invention discloses an ultrafine nano-liquid dispersion color paste, and the technical scheme adopted is as follows:

[0041] S1: Weigh 30g CI.R-54 Disperse Red and dissolve it in 100mL trichloroethylene solvent to obtain a disperse dye solution;

Abstract

The invention discloses superfine nanometer liquid dispersing color paste and a preparation method thereof. The dispersing color paste consists of the following raw materials in parts by mass: 20 to 60 parts of dispersing dye, 0.01 to 10 parts of a stabilizer, 0.1 to 10 parts of a solvent, 1 to 10 parts of a hyperdispersant, 0.1 to 10 parts of a wetting agent, 0.01 to 1 part of a sterilizing agentand the balance of water. The superfine nanometer liquid dispersing color paste is prepared by preparing a dispersing dye solution, dispersing a grinding system, stirring and grinding, recovering anorganic solvent, grinding again as well as filtering and separating grinding beads. The dispersing color paste provided by the invention has the advantages of high dyeing degree, avoidance of being stuck on a cylinder during dip dyeing, low COD and low chromaticity of dyeing residual liquid, safety, environmental friendliness, high stability, distribution uniformity and low cost, and is suitable for large-scale industrialized production and application.

Description

Technical field [0001] The present invention relates to the research field of disperse dyes, and more specifically to an ultrafine nano-liquid dispersion color paste and a preparation method thereof. Background technique [0002] The current development trend of the printing and dyeing industry at home and abroad requires the printing and dyeing process to be highly efficient, energy-saving and environmentally friendly. With the development of science and technology, the technical update of textile printing and dyeing has been comprehensively promoted and applied. However, my country's textile printing and dyeing industry has the status quo of low product grades and low added value, especially in the research of cleaner production, safe and harmless technology. There is still a certain gap in the country. [0003] Disperse dyes are a type of dyes with relatively small molecules and no water-soluble groups in the structure. It has been nearly a hundred years since disperse dyes wer...
