Description
Technical field
The invention belongs to digit printing ink-jet writing ink and its preparation and application field, in particular to a kind of water-fastness leather
Digit printing ink-jet writing ink and its preparation method and application.
Background technique
Leather has considerable always over the past thousands of years by people's pro-gaze in industries such as clothes, luggage, shoes, ornaments
Market value.Stamp can increase the artistic added value of leather and fur products, create more practicable economic values, however,
With the development of economy with the continuous improvement of people's level of consumption, traditional leather pattern-printing technology is unable to satisfy market to pattern printing skin
The individual demand of leather.Digital ink-jet printed technology is as a kind of green, environmental protection, individual character, the stamp production technology of fashion to skin
Leather this industry of stamp provides good development opportunity.
Digit printing ink-jet writing ink prints to form pattern on leather after, it is necessary to have good water-fastness, solarization and rub
The fastness such as wiping.Digit printing ink-jet writing ink can be divided into according to colorant: type of dye ink and pigment ink.Type of dye ink is deposited
In the disadvantage of gained Printing color fastness to water and fastness to light difference.Pigment ink has good fastness to light, but often
The aftertreatment technology of no mill base covering with paint is needed to obtain good water-fastness, crock fastness.It therefore meets leather digit printing sprays
Black one-step shaping is the following leather digit printing ink-jet without the color type digit printing ink-jet writing ink that aftertreatment technology requires
Development trend, have a vast market development prospect.
Application with printed leather in fields such as clothes, luggages, wash durability become its important indicator.Chinese patent
CN104231720A uses solvent dye for colorant, keeps it good to have in leather unlike material with molecular state infiltration
Good water-fastness and crock fastness, but its light fastness is not good enough.Color type leather digit printing ink-jet writing ink is to unlike material skin
The attachment of leather relies primarily on the adhesive effect of resin, therefore the selection of resin is most important, and patent CN103897492A selects special
Determine the acrylic resin of molecular weight, it is possible to provide there is good crocking resistance, still, because of propylene after leather digit printing ink-jet
The problem of the flexibility difference of acid resin causes washing fastness after leather digit printing poor.
Summary of the invention

Consider, can be used alone, can also any component two or more solvents different using boiling point, it is total that the content of solvent accounts for ink-jet ink
Weight is preferably 60-90%.
Ink flash-point viscosity at 60 DEG C or more, 25 DEG C is 3.0~10cp, and surface tension is 20~40mN/m.
The preparation method of the water-fastness leather digit printing ink-jet writing ink of one kind of the invention, comprising:
(1) dispersing agent is mixed with organic solvent, is stirred, pigment is added, obtains mixed liquor, ground, obtain mill base；
(2) mill base, resin and organic solvent in step (1) are mixed, after mixing, filtering (uses 0.2~2 μ
The filter of m), obtain leather digit printing ink-jet writing ink.
Mixing is to carry out at normal temperature in the step (1)；Mixing time is 0.1~1h.
Milling time is 5~20h in the step (1).
Mixing time is 0.5~4h in the step (2).
The application of the water-fastness leather digit printing ink-jet writing ink of one kind of the invention.
The present invention is modified by carrying out surface to pigment, is scattered in making pigment stabilizer using one or two kinds of dispersing agents
In organic solvent system, and the other compositions in dispersing agent and ink all have good compatibility；It adds elastomeric
Thermoplastic polyurethane resin (TPU) compounds the vinyl chloride-vinyl acetate resin of certain weight average molecular weight, and compounding mass ratio is TPU:P (VC-VAc)
=1:1~5:1, TPU have the characteristics that there is good flexibility after high resiliency can make ink form a film, and P (VC-VAc) resin has
Good solvent release, film forming, wearability and adhesive force, but elasticity is insufficient.When TPU:P (VC-VAc) < 1:1, ink
Toughness is inadequate, causes ink wash durability not good enough, and when TPU:P (VC-VAc) > 5:1, the wearability of ink is inadequate, causes to rub
Fastness is not good enough.Meanwhile high boiling organic solvent is added, the performance of keeping humidity of ink is provided, prevent ink assemble in the showerhead and
Spray head is blocked, the print performance of ink is effectively improved.The synergistic effects of two kinds of resins can get it is a kind of have good fastness to washing,
The Weak solvent leather digit printing ink-jet writing ink of excellent moisture retention, storage stability and discharge fluency.Printing test result
Show: ink prepared in accordance with the present invention has excellent discharge fluency and spray head performance of keeping humidity, ink-jet printed on leather
Washing fastness is up to 5 grades (GB/T 3921) afterwards.
Beneficial effect
The present invention passes through compounding thermoplastic polyurethane resin (TPU) and specific weight average molecular weight using pigment as colorant
Vinyl chloride-vinyl acetate resin can get good flexibility, adhesion and the good leather digit printing ink-jet writing ink of wash durability, can
Meet leather digit printing one-step shaping, is not necessarily to front and back treatment process, meanwhile, which has good moisture retention, spues surely
Qualitative and storage stability.With the modified granules of pigments size controlling of macromolecule dispersing agent in 100~300nm, storage in ink
It is not easy to be gathered into bulky grain insoluble matter in the process, to guarantee that ink system has excellent storage stability.Due to thermoplastic poly
The compounding of urethane resin (TPU) and vinyl chloride-vinyl acetate resin (P (VC-VAc)) synergistic effect, it is possible to provide ink figure after leather is ink-jet printed
Water-fastness, the fastness to rubbing of case, meet high saturation color coloured silk and excellent gloss, excellent application performance improve leather number
The added value of code stamp ink-jet, and the aftertreatment technology without being covered with paint, lacquer, colour wash, etc. without slurry.
