preparation example Construction

[0025] Another object of the present invention is to provide a kind of preparation method of the thermal sublimation ink based on the above-mentioned high coloring rate of disperse red dye, it comprises the following steps: (1) add successively the water of formulation amount, dispersant, solvent and Surfactant, carry out shear dispersion; Continue to add the disperse red 60 dyestuff of formulation amount in described container again, carry out stirring dispersion; (2) adopt the zirconia beads of different particle diameters to grind the product of step (1), The particle diameter of described zirconia beads changes from large to small; (3) add water of the same quality to the product of step (2), then centrifuge to remove large particle residues, filter to obtain color paste; (4) Color paste, wetting agent, leveling agent, solvent and water can be prepared in proportion to make sublimation ink.

[0026] In the step (2), zirconia beads of 0.6-0.8 mm, 0.25-0.35 mm and 0.1-0.2 mm...

Embodiment 1-12、 comparative example 1-3

[0029] Embodiments 1-12 and Comparative Examples 1-3 respectively provide a kind of sublimation ink based on disperse red dye with high coloring rate. In order to compare the influence of the color paste on its performance during preparation, the following fixed mass ratios are used for preparation, specifically It is: color paste 40%, wetting agent 5% (Surfynol 420), leveling agent 5% (EFKA-3033), water 30% and solvent 20%, that is, color paste 400g, Surfynol 420 50g, EFKA-3033 50g, 300g of water and 200g of solvent (the solvent used before and after remains the same); and the composition of the color paste is as shown in Table 1; its specific preparation method can be conventional, and the Chinese invention patent whose patent number is 201310270976.6 can be referred to, specifically: (1) After mixing the disperse dye and dispersant according to the formula ratio, use zirconium beads with a specification of 0.25-0.35mm in a sand mill at a speed of 2200-2800r / min, and grind an...

Embodiment 13

[0038] The present embodiment provides a kind of preparation method of the sublimation ink of high tinting rate based on disperse red dye, it comprises the following steps:

[0039] (1) Add water, dispersant, solvent and surfactant to the container successively according to the component content in Example 12, and carry out shear dispersion; then continue to add Disperse Red 60 dye in the container, stir to make it disperse evenly;

[0040] (2) Use zirconia beads of 0.6-0.8mm, 0.25-0.35mm and 0.1-0.2mm in turn to grind the products of step (a) for 0.5-5 hours, so that the particle size of the dye particles is D90≤200nm, D80≤ 150nm and D75≤100nm;

[0041] (3) in the product of step (2) (the dyestuff solid content of product is about 20%), add the water of its same quality, centrifuge then and remove large particle residue, use three grades of in-line filters to filter, filter to obtain color paste ( Solid content is reduced to about 10%); Finally, the color paste stability obt...

Abstract

The invention relates to high-coloring-rate thermal sublimation ink based on disperse red 60 dye and a preparation method of the thermal sublimation ink. The thermal sublimation ink contains the following components in percentage by mass: 35%-55% of color paste, 1%-10% of a wetting agent, 1%-10% of a flatting agent, 20%-58% of deionized water and 5%-20% of a solvent, wherein the color paste contains the following raw materials in parts by weight: 20-30 parts of the disperse red 60 dye, 25-35 parts of a solvent, 35-49.5 parts of water, 0.5-2 parts of a surfactant and 5-10 parts of a dispersing agent; and the surfactant is lignosulfonate with a sulfonation degree of 1.05mmol/g-2.0mmol/g. The color paste is prepared by compounding a specific amount of disperse red 60 dye, solvent, water, surfactant and dispersing agent, and the sulfonation degree of lignosulfonate is creatively controlled, and furthermore, the charge balance of the lignosulfonate after lignosulfonate is bonded with the dye is controlled, so that the dyes in the thermal sublimation ink can be still stably dispersed under a small particle size condition, and the thermal sublimation ink has the advantages of high coloring rate, strong coloring capacity and high color fastness and transfer rate in use.

Description

technical field [0001] The invention belongs to the field of thermal sublimation ink, and in particular relates to a thermal sublimation ink based on disperse red dye and having high coloring rate and color fastness and a preparation method thereof. Background technique [0002] Disperse red dye is a general term for a series of red dyes with red color, widely used in various products including leather, silk, nylon, fabric, wool due to its bright color, complete color spectrum and characteristics of high washing and light fast dehydration and fur making. Discharge of highly colored wastewater is one of the major environmental problems in the world today, as these types of wastewater and their metabolites are toxic, pathologically or carcinogenic, and pose potential health threats to all forms of life. [0003] Disperse red dye can be used for color development of ink, and in order to avoid its pollution to the environment, it can be printed by thermal transfer printing. Su...
