preparation example Construction

[0031] The preparation method for preparing the above-mentioned high color fastness inkjet printing pigment ink comprises the following steps:

[0032] For the preparation of ultra-fine coated pigments, first dissolve the polymerizable dispersant of the above ratio in the water of the above ratio, then put in the pH regulator, adjust the pH to 7~9, and then stir at 500~1200 rpm Add the pigment in the above ratio, stir evenly, transfer it to a sand mill, and grind it at a speed of 1600~2500 rpm for 1~5h to obtain an ultrafine pigment; then add the monomer in the above ratio dropwise, and continue grinding for 0.5 ~2h, take it out, transfer it to a four-necked flask equipped with a stirrer, a thermometer, and a condenser, feed in nitrogen, stir, raise the temperature to 60~90°C, slowly add the water-soluble initiator in the above ratio dropwise, and react for 0.5~10 After one hour, the reaction solution was taken out and filtered with a filter paper with a pore size of 500 nm to...

Embodiment 1

[0036] Dissolve 5.5g of allyloxynonylphenoxypropanol polyoxyethylene ammonium sulfate into 78.295g of water, add 0.2g of triethanolamine, and add 15g of carbon black pigment to the system at a stirring speed of 600 rpm , after stirring evenly, transfer it to a sand mill and grind it at a speed of 1600 rpm for 1.5 hours to obtain ultrafine carbon black, then add 1.00g of hydroxyethyl acrylate dropwise, continue grinding for 0.5 hours, take it out and transfer it to a machine equipped with a stirrer , thermometer, and condenser, feed nitrogen into the reactor, stir, heat up to 65°C, slowly add 0.005g ammonium persulfate dropwise, and react for 2.0 hours, take out the reaction solution, and filter it with filter paper with a pore size of 500nm to obtain ultrafine Coated carbon black pigment paste.

[0037] Weigh 40g of superfine coated pigment paste, then add 4g of ethylene glycol, 6g of isopropanol, 10g of glycerin, 2g of water-based polyurethane, 0.3g of Tween80, 0.1g of AFE-75...

Embodiment 2

[0039] Dissolve 6g of allyloxy hydroxypropyl sodium sulfonate into 71.695g of water, add 0.3g of sodium carbonate, and add 20g of C.I. Pigment Yellow 13 to the system at a stirring speed of 750 rpm, stir well and transfer to a sand mill Grind in the machine at a speed of 1800 rpm for 2 hours to obtain ultra-fine C.I. Pigment Yellow 13, then add 2g of propylene glycol diacrylate dropwise, continue grinding for 1 hour, take it out and transfer it to a reaction chamber equipped with a stirrer, a thermometer and a condenser Into the container, feed nitrogen, stir, heat up to 70°C, slowly add 0.005g of potassium persulfate dropwise, after 4.0 hours of reaction, take out the reaction solution, filter with filter paper with a pore size of 500nm, and obtain ultra-fine coated C.I. Pigment Yellow 13 colors pulp.

[0040] Weigh 30g ultra-fine coated C.I. Pigment Yellow 13, then add 5g of 1,3-propanediol, 10g of 1,4-butanediol, 15g of triethylene glycol, 5g of butane tetracarboxylic acid,...

Abstract

The invention discloses high-color-fastness inkjet printing pigment ink, which is characterized by comprising superfine coating pigment color paste, a water-soluble cosolvent, a cross-linking agent, a surfactant, a defoaming agent, a bactericide agent, a pH regulator and water, wherein the superfine coating pigment color paste comprises a polymerizable dispersing agent, a pH regulator, a pigment, a monomer, a water-soluble initiator and water. The surface of pigment particles is coated with a polymer through fine emulsion polymerization, so that the dispersion stability of the pigment particles can be improved, and reaction groups capable of bonding with the crosslinking agent can be provided; when the prepared ink is inkjet-printed onto textiles and roasted for fixation, the cross-linking agent and the polymer on the pigment surface are formed into a continuous, compact and smooth printing film on the surfaces of the textiles, so that the rubbing fastness of the inkjet printing ink can be improved, and the hand feeling of the printed textiles can be improved to certain extent.

Description

technical field [0001] The invention relates to a high color fastness inkjet printing pigment ink and a preparation method thereof, in particular to a high color fastness inkjet printing pigment ink and a preparation method thereof, belonging to the field of fine chemical science and technology. technical background [0002] Inkjet printing is a new type of textile printing technology recognized by the industry. This technology abandons the complicated process of plate making in traditional printing, greatly improves the printing accuracy, and realizes small batches, multiple varieties, multiple colors and personalized printing. Broad development prospects. Ink is an important consumable in digital printing production, and its research and development is a key step in promoting the development of digital inkjet printing technology. At present, the textile inkjet printing inks on the market are mainly dye inks, but due to the lack of versatility of dye inks, the printing pro...
