Dispersed dye, its molecule is less, and its particle diameter is usually below 2 μ m, containing water-soluble group not on structure, disperse and dyeed by means of the homogeneous in dye liquor that acts on of dispersion agent, its can on dye trevira, the dedicated dye of cellulose acetate fibre and polyesteramine fiber, especially terylene.Dispersed dye are broadly divided into DISPERSE ORANGE 30 200, EX-SF DISPERSE BLUE EX-SF 300, DISPERSE YELLOW, Disperse Red, can be arranged in pairs or groups according to a certain percentage by several different dispersed dye, obtain the dispersion dyestuffs such as dispersion is black, Disperse Green, 63 DISPERSE Violet 63.Dispersed dye can enter the intermolecular fabric coloring that makes of trevira by distillation, and its good dispersity can not produce precipitation and the obstruction shower nozzle, and can not affect the feel of fabric.

Wetting Agent for Printing Inks is water-miscible organic solvent, and dispersed dye in water-soluble solubleness organic solvent, can improve the performance of keeping humidity of ink for ink-jet print well, can also improve the rate of transform of dispersed dye simultaneously.

Viscosity-controlling agent is mainly used in regulating the viscosity of ink for ink-jet print, avoids ink feeding-up or excessively rare, increases its mobility, and can not affect the pliability of fabric.

Sterilant, for eliminating the various pathogenic micro-organisms of ink for ink-jet print, improves the stability of ink for ink-jet print, extends its storage time.

The potential of hydrogen of pH buffer reagent for regulating ink for ink-jet print, make ink for ink-jet print have certain basicity, and the one, improve its color, the 2nd, reduce the corrosive nature of ink for ink-jet print to shower nozzle.

Other components in resin liquid and the present invention cooperatively interact, make ink for ink-jet print can be on non-absorbability base material very fast dry, there is tack well, and can make the photostabilization with photostabilization material be unlikely to descend, there is again good physicals simultaneously.

Dispersion agent is a kind of interfacial agent that simultaneously has lipophilicity and two kinds of opposite nature of wetting ability in molecule, can disperse equably those difficulties to be dissolved in the solid particulate of inorganic, the pigment dyestuff of liquid, also can prevent sedimentation and the cohesion of solid particulate simultaneously.Dispersion agent can shorten the jitter time of dispersed dye in water-soluble system, the surface properties of modification dispersed dye particle, adjust the mobility of dispersed dye particle, can improve gloss, tinting strength and the opacifying power of ink for ink-jet print, improve its color developing and toning property, prevent floating and flocculation, dispersion agent and resin liquid have consistency well, have improved the thermostability of ink for ink-jet print.

Flow agent, can impel ink in the drying and forming-film process, form one smooth, smooth, film uniformly.

Defoamer, can prevent the generation of ink jet ink underwater bubble.

Tensio-active agent can improve the tension force on ink for ink-jet print surface, makes dispersed dye more stablize in water-soluble system and make ink for ink-jet print more fully moistening in print substrate.

Metal ion chelation agent can accelerate the volatilization of ink moisture after ink-jet, and can improve the luminance brightness of ink for ink-jet print.

Except water molecules, almost there is no any impurity in ultrapure water, can improve the quality of ink for ink-jet print.

Another object of the present invention is to provide the preparation method of this ink for ink-jet print of heat sublimation for industrial nozzle, technical scheme of the present invention is:

Be used for the preparation method of the heat sublimation ink for ink-jet print of industrial nozzle, comprise the following steps:

The preparation of mill base: get in proportion dispersed dye, dispersion agent and defoamer, go bail for again the humectant consumption 30～50%, 50～70% and ultrapure water consumption of dosage of surfactant 40～60%, mix at normal temperatures, stir, grind 20～30 hours, the median size of the mixture after making to grind is less than 150nm, obtains mill base;

(2) preparation of finished product: get in proportion sterilant, PH buffer reagent, viscosity-controlling agent, resin liquid, flow agent and metal ion chelation agent, get again wetting Agent for Printing Inks consumption, dosage of surfactant and the ultrapure water consumption of above-mentioned mill base, surplus, mix at normal temperatures, grinding distribution 1～2h, centrifugal, the strainer coarse filtration that aperture is 1 μ m after filtration, then the filtration of the strainer that aperture is 0.45 μ m and 0.22 μ m after filtration respectively essence, obtain finished product.

As a kind of improvement, in step (1), the median size of the described mixture after grinding is less than 90nm.

Owing to having adopted technique scheme, the invention has the beneficial effects as follows:

Heat sublimation for industrial nozzle ink for ink-jet print provided by the invention, can be fuming in transfer process few by the mode transfer printing of hot transfer printing, and the transfer printing time is short, and the rate of transform is high, and wash durability is strong; Also can realize by the mode of direct spray printing painted, because its viscosity is low, its ink-jet smoothness, can not stop up shower nozzle, and particle size dispersion is even, dispersion stabilization is good, and long-time the storage can not become corruption or sex change yet, the combination of pH buffer reagent, resin liquid and metal ion chelation agent makes pattern color and the degree of fixation of printing high, ink of the present invention rate of transform in transfer process is high, the dyestuff less residue, and after shifting, the color stereoscopic sensation is strong, the pattern interface edge is clear not fuzzy, and its cost is lower.Black ink prepared by the present invention is black especially, not colour cast.
