Embodiment 1

[0040] Raw material preparation for a disperse color paste: by weight, weigh PBK7 15%, EFKA4585 15%, ADISPONIL A 1580 2.5%, defoamer Airase5500 0.1%, BASF Joncryl 8055 5% and deionized water 62.4%.

[0041] Preparation method: use Netzsch 6L horizontal nano-sand mill imported from Germany. The cylinder body and tip of the grinder are wear-resistant steel structures. The zirconium beads used are imported zirconium beads with a diameter of 0.25mm. 1300rpm, grind for 18-20h, stop grinding when the particle size of the color paste is 95≤D50≤105nm, D99≤250nm, control the flow rate of the discharge port to 4kg / min, the temperature of the discharge port is 40±2°C, and get nano Grade disperse color paste.

[0042] Test color paste stability

[0043] Centrifuge the color paste at a speed of 10000rpm, filter it with a 1um PP melt-blown filter element imported from PALL, and then take a sample to test the aging stability (thermal stability of the color paste) at 60°C. The aging time is ...

Embodiment 5

[0050] Raw material preparation for a disperse color paste: by weight, PV23 15%, ZetaSperse 3400 15%, DISPONIL A 1580 2.5%, defoamer Airase5500 0.1%, BASF Joncryl 8055 5% and deionized water 62.4%.

[0051] Preparation method: use Netzsch 6L horizontal nano-sand mill imported from Germany. The cylinder body and tip of the grinder are wear-resistant steel structures. The zirconium beads used are imported zirconium beads with a diameter of 0.25mm. 1350rpm, grind for 18-20h, stop grinding when the particle size of the color paste is 95≤D50≤105nm, D99≤250nm, control the flow rate of the discharge port to 3kg / min, the temperature of the discharge port is 38±2°C, and the output will be nano Grade pigment dispersion color paste.

[0052] With the same preparation method as Example 5, different formulations were used to prepare color pastes, namely Examples 6-8 and Comparative Examples 5-8, and the specific formulations are shown in Table 2.

[0053] The color paste formula and perfo...

Embodiment 9

[0058] A kind of raw material preparation of water-based pigment ink-jet ink: by weight, take by weighing 38% of the nano-dispersion color paste of embodiment 1, acrylic resin 15%, glycerol 15%, 1,5-pentanediol 10%, Surfynol 485 0.8%, OP-15 0.5%, Proxel GXL 0.1%, Deionized Water 20.6%.

[0059] Preparation:

[0060] (1) Ink preparation: Turn on the mixer, add deionized water, set the stirring speed to 400rpm, add glycerol, 1,5-pentanediol, Surfynol 485, OP-15, Proxel GXL, stir for 20min until completely dissolved, add 15kg acrylic resin, stir for 20min, set the stirring speed to 600rpm, add 38kg PBK007 nano-pigment dispersion color paste, stir for 40min;

[0061] (2) Aging and filtering: After the preparation is completed, the test viscosity is 6.2, the surface tension is 30, all qualified, and then aged at 30°C for 24 hours, so that the components in the ink are completely dissolved, the dispersion system reaches equilibrium, and the insoluble substances and unstable The co...

Abstract

The invention provides a nano-scale water-based pigment jet ink. The nano-scale water-based pigment jet ink comprises the following raw materials: grinding resin, a dispersion mill base, a wetting surfactant, an emulsifying wetting agent, a water-soluble organic solvent, a bactericide and deionized water. A preparation method of the nano-scale water-based pigment jet ink comprises the following steps: (1) preparation of the mill dispersing and grinding a dispersion pigment, a dispersant, the emulsifying wetting agent, a defoamer, grinding resin and deionized water according to requirements on fineness to prepare the nano-scale pigment dispersion mill base; (2) preparation of an ink: adding water, then sequentially adding the water-soluble organic solvent, the wetting surfactant, the emulsifying wetting agent and other additives, performing stirring till complete dissolution, then adding main resin, performing uniform stirring, adding the nano-scale pigment dispersion mill base, and continually performing stirring and uniform mixing; and (3) aging and filtering: testing the viscosity and the surface tension after preparation of the ink, performing aging for 24-48 h after the ink is qualified, and performing filtering to obtain a final product. The provided nano-scale water-based pigment jet ink is smooth in printing and favorable in standby performance and ink jetting performance.

Description

technical field [0001] The invention belongs to the technical field of inkjet ink, in particular to a nano water-based pigment inkjet ink and a preparation method thereof. Background technique [0002] At present, there are mainly four mainstream printing methods, namely lithography, gravure printing, flexographic printing and screen printing. The characteristics of lithographic printing are fast plate making, large layout, easy overprinting of colors, strong layer reproduction ability, relatively low cost, widest printing range, books, newspapers, and magazines can be printed, and general pictures and color prints are almost all of them. The disadvantage of lithographic and lithographic printing is that it will be affected by water glue during printing, the color reproduction is low, and it lacks vividness; the biggest feature of gravure is that the printed matter is reproduced by the thickness of the ink layer, and the ink is thick, rich in layers, and expressive. It has ...
