Problems solved by technology

[0003] At present, whether it is a desktop inkjet printer or a large-format inkjet printer in China, because the original pigment ink is expensive, the instability of the compatible pigment ink is likely to cause blockage and damage to the ink head of the printer, and the color of the pigment ink is not as vivid and bright as the dye, so most of them use Water-based dye ink
The images printed by dye ink are bright in color, strong in image color reproduction, and the cost of dye ink is low, so that it has been widely used in the low-end market, but there is a problem of low weather resistance. In order to solve this problem, some domestic users Using a protective layer on the surface of the picture, although the weather resistance of the picture is improved to a certain extent, but the coating liquid has a certain destructive effect on the resolution of the picture, resulting in distortion of the picture, and at the same time, the production efficiency is reduced and the cost is increased.
Therefore, the disadvantages of the dye color developer of dye inks such as light fastness, gas resistance, water resistance, and high humidity, such as image fading and image blooming, limit the medium and high-end use of dye inks.

Embodiment 1

[0022] (1) Prepare a 20% solution of INDULOR styrene acrylic resin from Germany. The specific steps are as follows: add 79.9kg of deionized water to a 100L electric heating stirring tank, start the stirring and heating functions, and add 0.1kg of hydrogen carbonate to the stirring tank Ammonium and 20kg styrene acrylic solid resin, when the temperature is heated to 50±5°C, continue to stir for 3 hours, after the styrene acrylic resin is fully dissolved, cool down to room temperature, filter with a 2.0μm nylon filter element, and set aside.

[0023] (2) To prepare light-fast water-based dye inkjet printing ink, its raw material ratio is as follows in terms of mass percentage: 1412.7% of reactive red, 12.5% ​​of styrene acrylic resin with a content of 20%, 0.05% of benzotriazole, hindered amine 0.05%, fatty alcohol polyoxyethylene ether 0.2%, isopropanol 4%, ethylene glycol 6%, polyethylene glycol 4001%, TEGO 7000 12%, Amine Wanda 0.2%, isothiazolinone fungicide 0.1%, detox Ioni...

Embodiment 2

[0026] (1) Prepare light-fast water-based dye inkjet printing ink, and its raw material ratio is as follows by mass percentage: reactive red 1412.7%, fatty alcohol polyoxyethylene ether 0.2%, isopropanol 4%, ethylene glycol 6%, Polyethylene glycol 4001%, TEGO700012%, Amida 0.2%, isothiazolinone fungicide 0.1%, deionized water 73.8%.

[0027] (2) Accurately weigh the raw materials in step (1), add them to the electric heating stirring tank, stir for 2 hours when heated to 40±5°C, then stop stirring, lower to room temperature, and pass through the 1.0μm, 0.8μm, 0.45μm successively After the nylon filter element is filtered, it is the light-fast water-based dye inkjet printing ink, and the prepared ink is filled into a plastic bottle washed with deionized water for use.

Embodiment 3

[0029] (1) German INDULOR styrene acrylic resin was prepared into a 20% solution, and the specific preparation method was the same as in Example 1.

[0030] (2) Prepare the light-fast water-based dye inkjet printing ink, and its raw material ratio is as follows in terms of mass percentage: direct blue 1992.4%, content of 20% styrene acrylic resin 12.5%, benzotriazole 0.05%, hindered amine 0.05%, fatty alcohol polyoxyethylene ether 0.2%, isopropanol 4%, ethylene glycol 6%, polyethylene glycol 4001%, TEGO 7000 12%, Amine Wanda 0.2%, isothiazolinone fungicide 0.1%, detox Ionized water 61.5%.

[0031] (3) Accurately weigh the raw materials in step (2), add them into an electric heating stirring tank, stir for 2 hours when heated to 40±5°C, then stop stirring, lower to room temperature, and pass through 1.0μm, 0.8μm, 0.45μm successively After the nylon filter element is filtered, it is the blue ink for light-fast water-based dye inkjet printing, and the prepared ink is filled into...

Abstract

The invention discloses a sun-proof dye ink ink-jet printing ink. The sun-proof dye ink ink-jet printing ink is characterized by comprising the following components by mass percent: 2-5% of water soluble dye, 2-4% of styrene acrylic resin, 0.1-0.4% of an ultraviolet light absorber, 0.1-1.0% of a surfactant, 4-10% of isopropanol, 5-8% of ethylene glycol, 10-20% of a humectant, 0.2-0.5% of a pH stabilizer, 0.1-0.2% of a bactericide and the balance of deionized water. The sun-proof dye ink ink-jet printing ink is strong in stability, effectively improves the light fastness, the weather fastness,the acid resistance and the waterproofness of printed words and images, and solves the problems of fading and shading of the image, the output quality of the image is high, the color rendition is vivid, and an ink head of a printer is effectively protected.

Description

technical field [0001] The invention relates to water-based dye ink, in particular to a light-fast water-based dye inkjet printing ink. Background technique [0002] Inkjet printing ink is a kind of "liquid ink" that is sprayed on a predetermined area on the surface of the substrate to form imprints of graphic information by means of the electric field force between the nozzle of the inkjet printer and the substrate. [0003] At present, whether it is a desktop inkjet printer or a large-format inkjet printer in China, because the original pigment ink is expensive, the instability of the compatible pigment ink is likely to cause blockage and damage to the ink head of the printer, and the color of the pigment ink is not as vivid and bright as the dye, so most of them use Water-based dye ink. The images printed by dye ink are bright in color, strong in image color reproduction, and the cost of dye ink is low, so that it has been widely used in the low-end market, but there is ...
