Embodiment 1

[0026] Example 1: Black Dye Sublimation Inkjet Ink

[0027] A water-based digital printing sublimation inkjet ink, which includes the following components by mass percentage: 10% resin, 30% color paste, 20% solvent, 0.5% bactericidal preservative, 0.5% pH regulator, wetting Agent 1.5%, deionized water 37.5%.

[0028] The above dye-sublimation inkjet ink is made according to the following steps:

[0029] 1) Put the formula amount of deionized water, solvent, bactericidal preservative, and pH regulator into the material bucket in order, and stir at a speed of 500r / min for 20 minutes; add the formula amount of wetting agent and continue stirring until the solution is clear as a whole Add the amount of resin in the recipe and continue to stir until the solution is clear as a whole;

[0030] 2) Add the formulated amount of color paste and stir for 20 minutes at a speed of 500 r / min; then filter with a combination of a 0.22 μm hydrophilic filter membrane and a 0.45 μm hydrophilic ...

Abstract

The invention discloses water-based digital printing thermal dye sublimation jet ink and belongs to the technical field of thermal dye sublimation ink. The thermal dye sublimation jet ink is preparedfrom components in percentage by mass as follows: 1%-10% of resin, 5%-50% of color paste, 10%-50% of a solvent, 0.1%-1% of an antibacterial preservative, 0.1%-1% of a pH regulator, 0.1%-3% of a wetting agent and 10%-50% of deionized water. The thermal dye sublimation jet ink has better printing smoothness and stability and high sharpness, the quick drying property is greatly improved, the printingeffect is good, and the applicability to an EPSON MT4114 nozzle is also improved.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a water-based digital printing sublimation inkjet ink. Background technique [0002] Dye-sublimation ink (also known as thermal transfer ink) is to make low-energy, easy-to-sublimate disperse dyes into digital printing inks, print on transfer paper, and heat images in the shortest time to produce exquisite porcelain, Metal, silk, chemical fiber cloth and other materials are very suitable for the market needs of individual development and environmental protection requirements. Most of the sublimation inks are prepared from disperse dyes for textiles. Due to their saturated colors and good weather resistance, disperse dyes Therefore, it is widely used in textile printing and dyeing, and it is still one of the main raw materials in the printing and dyeing industry so far. However, the existing dye-sublimation inks often lead to problems of poor fluency and clogging of the nozzles durin...
