Embodiment 1

[0046] Raw material preparation for a color paste: weigh R60 20%, lignin 970 8.5%, emulsifier A233S 3%, 44000 3.5%, 690W 1.5%, glycerin 20%, PROXEL GXL 0.2%, defoamer 104E 0.05 %, the balance is deionized water.

[0047] The preparation method of nano-color paste: put R60, lignin 907, lignin 907, 44000, A233S, 690W, glycerin, PROXEL GXL, defoamer 104 and deionized water into a total of 200KG, and put them into the dispersion barrel at 1200rpm for 2 hours, and then The 80-mesh filter bag is filtered and transferred to the grinder for dispersion and grinding. The speed of the grinder is 1200-1250rpm, the grinding time is controlled at about 45-60h, the flow rate of the outlet is 6-8kg / min, and the temperature of the outlet is controlled at 40±5°C, to obtain nano-scale color paste with a particle size of 100nm≤D50≤130nm, 250nm≤D99≤280nm; the grinder is a NETZSCH 10L horizontal nano-sand mill imported from Germany, and the cylinder and tip of the grinder The support is made of we...

Embodiment 9

[0059] A kind of raw material preparation of nano water-based thermal transfer printing ink: by weight, take by weight 28% of the color paste of embodiment 1, 1,3-propanediol 5%, glycerol 25%, 1,5-pentanediol 10% %, DS960 0.8%, emulsifier B 690W 0.5%, ProxelGXL 0.1%, and the balance is deionized water.

[0060] The preparation method of above-mentioned nano water-based thermal transfer printing ink, comprises the following steps:

[0061] (1) Turn on the mixer, add deionized water, and then add 1,3-propanediol, glycerin, 1,5-pentanediol, DS960, emulsifier 690W and Proxel GXL while stirring at a speed of 500rpm, and stir for 20 -30min to mix evenly, add the nanoscale dispersion color paste of embodiment 1, continue to stir 30-60min with the speed of 600rpm;

[0062] (2) Test the viscosity and surface tension of the homogeneously mixed mixture in step (1). The viscosity range is 5-6.5mpa.s, and the surface tension range is 30-40mN / cm, all qualified, and then aged at 35°C After...

Abstract

The invention provides nano waterborne heat transfer printing ink applicable to the high-speed printing of a Kyocera ink-jet head. The nano waterborne heat transfer printing ink comprises nano color paste, propylene glycol, glycerol, pentadiol, a wetting agent, an emulsifier B, a sterilizing agent and deionized water, wherein the color paste comprises salt-free refined dispersing dye, a dispersingagent A, a dispersing agent B, glycerin, a sterilizing agent, a defoaming agent and deionized water. The nano waterborne heat transfer printing ink applicable to the high-speed printing of a Kyoceraink-jet head has the advantages that the ink is good in standby performance, stable in long-term printing performance, free of excessive ink marks, good in color stability and reducibility, excellentin performance such as washing resistance, dry and wet scratch resistance and sun resistance, capable of satisfying digital printing requirements (the dry and wet scratch resistance reaches level 4-5,the washing resistance reaches level 4-4.5, and the sun resistance reaches level 3.5-4.5), environmentally friendly and nontoxic and passes REACH and Intertek certification, and the ink has good compatibility with the Kyocera ink-jet head and is widely applicable to the printing of a printer with the Kyocera ink-jet head (KJ4B-300DPI).

Description

technical field [0001] The invention belongs to the technical field of ink-jet inks, in particular to a nano water-based thermal transfer printing ink suitable for high-speed printing in Kyocera nozzles and a preparation method thereof. Background technique [0002] Digital transfer printing, also known as digital thermal transfer printing or digital inkjet transfer printing, is to use digital technology to print and process textiles containing man-made chemical fiber components. The processing process is simply to input images into The computer, after editing and processing by the printing software system, forms the required pattern, and then controls the printing by the output software, prints various special thermal transfer inks on the paper, and then transfers them to the chemical fiber after heating and fixing at 180-220°C On the fabric, printed textiles with high-precision patterns are obtained. The washing fastness is 4-4.5, and the dry and wet rubbing is 4-5, which ...
