preparation example Construction

[0026] The preparation method of quick-drying water-based ink-jet ink of the present invention comprises the following steps:

[0027] Water-dispersed resin accounting for 0.1-20% (preferably 14-20%) of water-based inkjet ink, 0.1-10% (preferably 3-8%) of colorant, 4-8% (preferably 5-8%) 65~90% (preferably 65~75%) of deionized water is mixed with 0.1~7% (preferably 0.5~3%) of wetting agent and 0.1~5% ( 0.1~1%) drier is added to the solution in sequence, and the stirring is continued for 5~15 minutes, and the stirring speed is controlled at 50~100rpm during the whole process. Impurities in the solution are removed by filtration to obtain a quick-drying water-based inkjet ink.

Embodiment 1

[0029] In terms of mass percentage, the distribution ratio of each component of the quick-drying water-based inkjet ink is:

[0030] Silicone modified styrene-acrylic emulsion 16%

[0031] Water-based acid dye 5%

[0032] Ethanol 5%

[0033] Polyether modified polydimethylsiloxane 1%

[0034] Water-based cobalt drier 0.5%

[0035] Deionized water 72.5%.

[0036] Mix silicone-modified styrene-acrylic emulsion accounting for 16% of the total amount of water-based inkjet ink, 5% water-based acid dye, 5% ethanol and 72.5% deionized water, and stir at room temperature at the same time, and then 1% of the The polyether-modified polydimethylsiloxane and 0.5% aqueous cobalt drier were sequentially added into the solution, and the stirring was continued for 10 minutes, and the stirring speed was controlled at 80 rpm during the whole process. Impurities in the solution are removed by filtration to obtain a quick-drying water-based inkjet ink.

Embodiment 2

[0038] In terms of mass percentage, the distribution ratio of each component of the quick-drying water-based inkjet ink is:

[0039] Silicone modified acrylic emulsion 16%

[0040] Water-based basic dye 5%

[0041] Ethanol 5%

[0042] Polyether modified polydimethylsiloxane 2%

[0043] Water-based zirconium drier 1%

[0044] Deionized water 71%.

[0045] Mix silicone-modified acrylic emulsion, 5% water-based basic dye, 5% ethanol and 71% deionized water, which account for 16% of the total amount of water-based inkjet ink, and stir at room temperature at the same time, and then 2% of the The polyether-modified polydimethylsiloxane and 1% water-based zirconium drier were sequentially added into the solution, and the stirring was continued for 12 minutes, and the stirring speed was controlled at 70 rpm during the whole process. Impurities in the solution are removed by filtration to obtain a quick-drying water-based inkjet ink.

Abstract

The invention discloses a quick-drying type water-based ink-jet ink and a preparation method thereof. The ink is prepared from the following ingredients in percentage by mass: 0.1-20% (preferably 14-20%) of water dispersion resin, 0.1-10% (3-8%) of pigment, 4-8% (preferably 5-8%) of cosolvent, 0.1-7% (preferably 0.5-3%) of wetting agent, 0.1-5% (preferably 0.1-1%) of drier, and 65-90% (preferably 65-75%) of deionized water. The ink system contains the wetting agent and drier, thus being applied onto an absorptive or non-absorptive base material, showing a quick-drying effect, and solving the difficulty that the water-based ink printed is not easy to dry. The drier not only promotes the molecule arrangement orderliness of the water-based ink, being helpful to fast volatilization of water, and improvement of the adhesive force of the water-based ink; furthermore, the surface of an ink layer is to fast dry, the adhesion on the back of printing products can be solved, and the quality of printed products can be improved.

Description

technical field [0001] The invention relates to an ink and its preparation, specifically a quick-drying water-based inkjet ink and a preparation method thereof. Background technique [0002] Generally, the ink containing at least 70% water in the solvent can be called water-based ink, or ink for short. Water-based ink is an ancient and emerging ink. According to historical records, my country invented water-based ink as early as 220-420 A.D. This ink is suitable for printing paper and wood products. With the development of printing technology and petrochemical industry in the 17th and 18th centuries, the early water-based inks were no longer suitable for the printing of metal products and non-absorbent materials, so oily and solvent-based inks appeared, and almost no one cares about water-based inks. In the 1970s, with the increasing awareness of environmental protection and the development of new water-based resin products, water-based inks were re-emphasized, and the app...
