Solvent dye ink-jet printing ink and preparation method thereof

Abstract

The invention relates to a solvent dye ink-jet printing ink and a preparation method thereof, relating to an ink. The solvent dye ink-jet printing ink comprises the following components: 5%-8% of acrylic resin, 1%-8% of colorant, 0.1%-1% of acidity regulator, 0.01%-0.02% of defoaming agent, 0.01%-12% aminating agent, 0.01%-1% of surfactant, 0.01%-0.02% of drier, and the balance solvent. When in preparation, all raw materials are poured into a sealed reaction kettle according to the above formula, and then a shearing mulser is utilized for shearing and stirring to obtain the solvent dye ink-jet printing ink. Printed pictures have good definition, and the copper plate paper of the printing ink has a color gamut range which can be up to national ink-jet printing standard; images can be clearly formed on printing stock medium without a coating layer; the ink has good fluency and unblocks the ink jet head of the ink jet printer within one week, has good the water-proof performance and light stability, can not corrode the printer, is safe, protects environment, and can be applicable to brand ink jet printers such as EPSON and the like.

Description

technical field [0001] The invention relates to an ink, in particular to a solvent-type dye inkjet printing ink and a preparation method thereof. Background technique [0002] Since digital proofing is an important part of printing, the development of digital printing is restricted by the cost and technology of digital proofing consumables, and the long-term development is slow. [0003] At present, with the increasing popularity of inkjet printers, inkjet printers are increasingly accepted by more consumers, and printer inks are becoming more and more popular. Inkjet printing ink is an important part of inkjet printing materials. Its quality and performance are closely related to the quality of the printed image, and also greatly affect the characteristics of the ink droplet nozzle of the printer and the use effect of the printing system. In order to obtain excellent printing characteristics, the printing ink, printing paper and printer must match. Although the types of p...
