Embodiment 1

[0026] Preparation of blue ink:

[0027] (1) Preparation of color paste, respectively weigh 6g polymer dispersant HT-601 (Nantong Hantai Chemical Co., Ltd.), 10gC5 hydrogenated petroleum resin C-115W (Nanjing Yangzi Eastman Chemical Co., Ltd.), 74g Isopar E. Stir and mix evenly at room temperature, add 10g of C.I. Disperse Blue 14 to the mixture while stirring, and then use a grinder to grind for 25 hours at a speed of 3500 rpm to obtain a uniformly dispersed and stable blue ink color paste . (2) Preparation of ink, weigh 25g of the above-mentioned color paste, add 12.5g of G3H and 12.5g of soybean oil, then stir at room temperature for 1 hour at high speed, then filter with a filter with a pore size of 0.45μm to obtain blue oily sublimation ink. When the temperature of this ink is 25°C, the surface tension is 29mN / m, the viscosity is 7.8cP, and the average particle diameter of the disperse dye particles is 270nm.

Embodiment 2

[0029] Preparation of red ink:

[0030] (1) Preparation of color paste, respectively weigh 6g polymer dispersant UG-230 (Shenzhen Propeller Chemical Co., Ltd.), 10g alkylphenol resin EPS30RA (Yanshan Petrochemical), 74g Exsol D130, stir and mix evenly at room temperature , while stirring, add 10g of C.I. Disperse Red 60 to the mixture, and then use a grinder to grind for 25 hours at a speed of 3500 rpm to obtain a uniformly dispersed and stable red ink paste. (2) Preparation of ink, weigh 25g of the above-mentioned color paste, add 20g of Isopar M and 5g of peanut oil, then stir at a high speed at room temperature for 1 hour, and filter with a filter with a pore size of 0.45 μm to obtain a red oily sublimation ink. When the temperature of this ink is 25°C, the surface tension is 28.7mN / m, the viscosity is 7.9cP, and the average particle diameter of the disperse dye particles is 230nm.

Embodiment 3

[0032] Preparation of yellow ink:

[0033](1) Preparation of color paste, respectively weighed 6g polymer dispersant HT-603 (Nantong Hantai Chemical Co., Ltd.), 10g 210# rosin modified phenolic resin (Shanghai Nanda Chemical Factory), 74g Isopar G, at room temperature Stir and mix evenly, add 10g of C.I. Disperse Yellow 50 to the mixture while stirring, and then use a grinder to grind for 20 hours at a speed of 3500 rpm to obtain a uniformly dispersed and stable yellow ink color paste. (2) Preparation of ink, weigh 25g of the above-mentioned color paste, add 12.5g of Exsol D130 and 12.5g of rapeseed oil, then stir at a high speed at room temperature for 1 hour, and filter with a filter with a pore size of 0.45μm to obtain yellow oily Dye sublimation ink. When the temperature of this ink is 25°C, the surface tension is 28.6mN / m, the viscosity is 8.0cP, and the average particle diameter of the disperse dye particles is 180nm.

Abstract

The invention relates to oily digital ink-jet printing thermal sublimation printing ink and a preparation method thereof. The printing ink comprises the following components in percentage by mass: 1 to 10 percent of disperse dyes, 0.5 to 15 percent of resin, 1 to 15 percent of polymer dispersant and 60 to 95 percent of oily dispersion medium. The preparation method thereof comprises the following steps: stirring 0.5 to 15 percent of resin, 1 to 15 percent of polymer dispersant and 60 to 95 percent of mineral oil, adding 1 to 10 percent of disperse dyes into the mixture for grinding to prepare color paste; and after stirring and mixing 10 to 100 percent of color paste with 0 to 90 percent of oily dispersion medium fully and uniformly, filtering the mixture by 0.2 to 2 mu m of filter to prepare the oily digital ink-jet printing thermal sublimation printing ink. The printing ink has the advantages of excellent moisture retention, storage stability, spit fluency, and simple preparation process.

Description

technical field [0001] The invention belongs to the field of ink and its preparation, in particular to a preparation method of oily digital inkjet printing sublimation ink. Background technique [0002] The inkjet recording method is based on electrical signals from a computer, etc., using pressure, heat, electric field, etc. as a driving source, and ink droplets are jetted from a print head or nozzle to a recording material at high speed for printing. High-precision images can be obtained by inkjet recording, so it has been widely used in the fields of copying, facsimile, advertising, and display. [0003] Inks used in the above-mentioned inkjet recording method generally use water-based inks using water as a dispersion medium and solvent-based inks mainly using organic solvents. Images obtained from water-based inks usually have poor water resistance and are difficult to print on recording materials with hydrophobic surfaces. However, solvent-based inks can obtain printed...
