Embodiment 1

[0028] Embodiment 1: the preparation of blue ink

[0029] (1) Preparation of blue color paste: Weigh 12.5g of dispersant BYK191, 20g of diethylene glycol, 0.05g of fungicide SZSH-S, and 47.7g of deionized water, and add 20g of C.I. Disperse Blue 72 during stirring. Then fully grind to obtain 100g of uniformly dispersed and stable blue color paste. Measure its particle size, less than 1 micron.

[0030] (2) Preparation of blue ink: Weigh 20g of blue color paste, add 6g of diethylene glycol, 6g of isopropanol, 2g of 1,6-hexanediol, 0.6g of surfactant FS-640, add 4g of sodium sulfate, remove 12.3g of ionized water, after fully stirring at room temperature, filtered with a 0.45μm filter to obtain 50g of blue inkjet code dispersion ink.

Embodiment 2

[0031] Embodiment 2: the preparation of red ink

[0032] (1) Preparation of red color paste: Weigh 10g polystyrene maleic anhydride homopolymer dispersant, 28g diethylene glycol, 0.03g BIT fungicide, 42.4g deionized water, add 20g C.I. 60. Then fully grind to obtain 100g uniformly dispersed and stable red color paste. Measure its particle size, less than 1 micron.

[0033] (2) Preparation of red ink: Weigh 20g of red color paste, add 5.5g of diethylene glycol, 6g of isopropanol, 2g of 1,6-hexanediol, 0.6g of surfactant OP-7, 0.1g of AD-100 for defoaming Agent, potassium sulfate 3.8g, deionized water 12g, after fully stirring at room temperature, filter with a 0.45μm filter to obtain 50g of red inkjet code dispersion ink.

Embodiment 3

[0034]Embodiment 3: the preparation of yellow ink

[0035] (1) Preparation of yellow color paste: Weigh 23g of lignosulfonate dispersant, 19g of diethylene glycol, 0.07g of BIT fungicide, and 38g of deionized water, and add 20g of C.I. Disperse Yellow 54 during stirring. Then fully grind to obtain 100g uniformly dispersed and stable yellow color paste. Measure its particle size, less than 1 micron.

[0036] (2) Preparation of yellow ink: Weigh 20g of yellow color paste, add 5.5g of diethylene glycol, 5.6g of isopropanol, 2g of 1,6-hexanediol, 0.6g of surfactant Pingpingjia 0-25, sodium sulfate 0.5 g, 15.8 g of deionized water, after fully stirring at room temperature, filter with a 0.45 μm filter to obtain 50 g of yellow inkjet code dispersion ink.

Abstract

The invention discloses water-based digital ink jet dispersed ink and a preparation method and application thereof. The formula of the ink comprises 5 to 15 percent of dispersed dye and 1 to 8 percent of electric conductance regulator. The preparation method comprises the following steps of: mixing a dispersant, the dispersed dye, partial water-soluble organic solvent and partial deionized water,and grinding the mixture to obtain color paste; and then adding the electric conductance regulator, a surfactant, an additive, the rest water-soluble organic solvent and the reset deionized water into the color paste, and stirring and filtering to obtain the ink. The ink has good printing smoothness and nozzle moisturizing performance, can be adaptive to code spraying machines of various models, has the advantages of bright color, light resistance, washing resistance, abrasion resistance, strong firmness and the like when printed on chemical blended fabrics, and is suitable for spraying production date, batch number, bar code, pictorial trade mark, false-proof mark and Chinese character of textiles and printing blanket patterns and the like.

Description

technical field [0001] The invention relates to the field of water-based disperse dye ink set and its preparation, in particular to a water-based disperse dye ink set suitable for inkjet printers and a preparation method thereof. technical background [0002] The inkjet printer is a high-tech product integrating electromechanical integration by using charged ink particles and deflecting them by a high-voltage electric field to print patterns and numbers on the surface of various objects. The products are widely used in various industries and fields. This machine can be used to print production date, batch number, bar code, trademark pattern, anti-counterfeiting mark and Chinese characters, etc. Compared with inkjet printers, inkjet printers have obvious advantages, that is, the printing speed is fast, and they can meet the needs of personalized printing in current industrial production. [0003] When developing inkjet suitable for inkjet printers, the requirements for inkje...
