Description
Technical field
The present invention relates to printed material technical field, be specifically related to a kind of digital ink and preparation method thereof。
Background technology
Digital ink-jet printed is that pattern is passed through scanner, layout is retouched original text system editing and processing by computer color separation in printing, controlled minute-pressure electric-type ink nozzle by computer again and special dye liquor (being referred to as digital ink-jet printed ink) is directly injected on textile, after color mixture, be reduced into original scan pattern。As the digital ink of one of digital ink-jet printed main consumptive material, it also it is the key factor determining ink-jet printed technology success or not。In prior art, digital ink raw materials particle diameter is big, and it is poor to permeate, and attachment degree is low；Spray printing fastness is low, not water-fastness, not sun-proof, easily causes color flower, mottle during spray printing；Raw material particle size is easy to greatly blocking digital spray head, and stamp is not smooth, it is necessary to often change digital spray head, unfavorable protection digital machine；And it is generally required to high-temperature steam presses after stamp, time consumption and energy consumption。
Summary of the invention
In view of this, it is necessary to for above-mentioned problem, it is provided that a kind of digital ink and preparation method thereof。
For achieving the above object, the present invention takes following technical scheme:
The digital ink of the present invention, its mass percent consists of:
Further, described wetting agent includes the alcohols such as glycerol, hexanediol, pentanediol；Described penetrating agent is Polyethylene Glycol；Described surfactant is fatty alcohol ethers or triglyceride。A kind of preparation method of digital ink, including:
Step 1, the penetrating agent by formula, wetting agent, surfactant are slowly added into reactor successively, open speed of agitator 70rpm, are slowly added in formula the 50% of distilled water total content, and adding distilled water duration is 10 minutes；Being slowly added into mill base again, the persistent period adding mill base is 15 minutes；Carry out low rate mixing；
Step 2, weigh remaining distilled water in formula and be slowly added in reactor low rate mixing 30 minutes, add preservative；
Step 3, with pH blender adjust product pH value be 7.5-8.5, control product surface tension force at 35-42mN/m, when 25 DEG C, viscosity is 3-5cps；
Step 4, complete after stand, filter discharging。
The invention have the benefit that
1, the present invention selection by raw material, prepares the digital ink of wide, the effective high osmosis of the suitability and high fastness, and the more traditional ink of the present invention reduces the cost of 2-5%。
2, the raw material feature of environmental protection of the present invention is higher, conductivity is less, penetration is better, and final products adhesive force is big, and the fastness of stamp, water-fastness, sun-proof dynamics, resistance to dry, fastness to wet rubbing etc. are all improved。
3, particle diameter less (0.2-0.8um), stamp is more smooth, will not block digital spray head, better protects digital machine。Stamp spray-painting is evenly painted, and decreases aberration, avoids mottle。Stamp is once completed by digital spray printing, it is not necessary to steam ironing；Technique is simple to operation；Product quality is substantially improved。
4, product of the present invention is without formaldehyde, without APEO, without organic solvent, without heavy metal ion；Without allergy, teratogenesis, mutagenesis, the ill effect such as carcinogenic, safe to the human body, meet European Union's OeKo-TEXStandard100, REACH standard-required。Process of producing product does not have the three wastes produce, the problem producing a large amount of contaminated wastewater environment when solving traditional dyeing；Working place saves more than 60% than traditional dyeing。
