Water-based digital ink jet dispersed ink and preparation method and application thereof

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.
