Color ink-jet printing ink and preparation method thereof

Abstract

The invention discloses a color ink-jet printing ink and a preparation method thereof. The color ink-jet printing ink comprises the following components in parts by weight: 60-80 parts of deionized water, 8-12 parts of triethanolamine, 5-10 parts of a water-soluble organic wetting agent, 6-8 parts of a wetting binder, 6-8 parts of a cellosolve, 5-7 parts of acrylic resin, 4-6 parts of a colorant, 0.2-0.4 part of a surfactant, 0.1-0.2 part of a preservative and 0.01-0.02 part of a drying agent, wherein the colorant is metal complex dye; the drying agent is selected from ethanol, isopropyl alcohol or 1-cyclohexyl-2-pyrrolidone; the water-soluble organic wetting agent is 1,2-propanediol, glycerine, ethylene glycol, diglycol, triethylene glycol or sorbitol; the wetting binding agent is 2-pyrrolidone, sodium sorbate, polyvinyl pyrrolidone or potassium sorbate. The color ink-jet printing ink is safe, environment-friendly, excellent in definition of a printed image, moderate in surface tension, viscosity and electrical conductivity, capable of clearly imaging on a printing stock medium without a coating, excellent in ink smoothness, unlikely to block an ink-jet printer ink gun, good in water resistance and photostability, and free of corrosion of a printer.

Description

technical field [0001] The invention relates to the technical field of printing consumables, in particular to a color 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...

AI Technical Summary

Problems solved by technology

[0007] 1. The color density is low, there is color difference, and the color is not bright;

[0008] 2. The continuous performance of printing is not good, and it is easy to plug;

[0009] 3. The clarity of the printed image is low, that is, the printed text and image are not neat, and there are phenomena of diffusion, melting, lack of ink, unevenness and ink droplet splashing;

[0010] 4. Poor waterproof performance and light stability
