Abstract
The invention relates to an ink composition capable of reducing jetting resistance of ink of an ink-jet printer for the ink-jet printer. The ink composition consists of (1) alcohol with carbon-carbon triple bond and (2) sulfonate with a fluorocarbon structure. Experiment results show that resistance in an ink jetting process of the ink-jet printer can be obviously reduced when the ink composition is used, and accordingly the quality of an ink-jet printed image is greatly improved.
Description
Technical field
The present invention relates to the composition for ink in the ink for ink-jet printer prescription.
Background technology
Spray ink Printing is that the non-contacting mode of a kind of employing is carried out method of printing; Through nearly 30 years development; Not only in office, be used for the output of computer version image at present; And also obtained widespread use in textile printing and dyeing, circuit manufacturing, field such as three-dimensionally shaped, particularly in the textile printing and dyeing field. use in recent years environmental protection, economy, flexibly digital printing and dyeing mode to replace the trend of traditional textile printing and dyeing obvious day by day.But the digital printing and dyeing ink as important component part in the number printing and dyeing is faced with the technological development bottleneck, is in particular in that the desired high density tinting material of printing and dyeing brings high resistance and the inkjet printer head flying print contradiction to the desired low injection resistance of ink when working of spraying.
If temporary transient Considering Surface tension force not; The factor that influences ink for ink-jet printer injection resistance mainly is the fluid type of ink; Used ink for ink-jet printer is because of colorant concentration lower (being lower than 4%) in the office, so can regard shear-stress and the linear Newtonian fuid of shearing rate as, the resistance during injection is relatively low; But the ink for ink-jet printer that printing and dyeing are used is because colorant concentration higher (requiring 6%-10%); Can not simply regard Newtonian fuid as, but just can cause mobile non-Newtonian fluid (Stuart Bingham Bingham fluid) when having only impellent to surpass certain value, the resistance during injection is higher relatively.
For the height of alleviating digital printing and dyeing ink sprays the contradiction between resistance and the desired low injection resistance of ink-jet printer, relevant at present publication is mainly through improving the mode that inkjet printer head improves the jet power of shower nozzle.Wherein more representational patent report: the mode of the shared wall of U.S. Pat 7497554 report uses of exercise question " Ink jet print head " drives the high viscosity ink and sprays; But when improving jet power, its image fine degree obviously descends.
Therefore; But providing a kind of can be the task of top priority in the art at the ink of the relatively low high-precision high-speed degree shower nozzle works better of jet power satisfying the requirement of digital printing and dyeing high density tinting material, and wherein gordian technique provides a kind of combination of inks that reduces the ink jet resistance.
Summary of the invention
One of the object of the invention be the composition for ink that a kind of obvious reduction ink jet resistance is provided under the prerequisite of high density tinting material make its can be on the relatively poor relatively high precision shower nozzle of jet power works better.
Above-mentioned purpose of the present invention is to reach through the mode that in ink set, adds compsn.
A kind of composition for ink that can reduce the injection resistance, comprising:
(1); The alcohols of carbon-carbon three key, the preferable amount of said alcohols are 1-5%, and described alcohols comprises 3 hexins-2,5 dimethyl--2; 5 glycol, 3 hexins-2,5 glycol, propiolic alcohol, 2-butine-diethoxy-1,4-glycol etc.; Wherein be preferably 3 hexins-2,5 dimethyl--2,5 glycol.
(2); The sulphonate of fluorine-containing carbon structure, the preferable amount of said sulphonate are 1-5%, and described sulphonate comprises perfluoro butyl sulfosalt, perfluoro propyl sulphonate, perfluor amyl group sulphonate etc., wherein is preferably perfluoro propyl sulphonate.
A kind of optimal technical scheme; It is characterized in that: described can the reduction in the composition for ink that sprays resistance contains the high density coloring agent component; Its content is 6-10%; Described high density tinting material comprises reactive dyestuffs, dispersed dye, dispersed color etc., and wherein the combination of inks described in the present invention is that the digital printing and dyeing ink of dispersed dye and dispersed color is effective especially for tinting material.
A kind of optimal technical scheme is characterized in that: contain some nonessential compositions in the described composition for ink that can reduce spray resistance, PH buffer reagent for example, metal chelator, biological bactericide.Though their adding can't directly influence jet performance, the result of use after the preservation that can influence.
Beneficial effect:
In high density dispersed dye ink, add the composition for ink that reaches described in the present invention, the printing test bar before and after contrast adds:
Fig. 1 does not add the ink of composition for ink
Fig. 2 adds the ink of composition for ink
Above result shows, under the prerequisite that guarantees the high density tinting material, through adding the composition for ink described in the present invention, can guarantee the quickening of test strip lines response speed, and the resistance when effectively reducing ink jet improves print quality.
The alkanol molecule of analyzing carbon-carbon three key that contains in the composition for ink of addressing before its reason possibly be is adsorbed on the surface of colourant molecule; And the sulphonate of the fluorine-containing carbon structure that contains in the composition for ink is adsorbed on the alkanol molecule outside surface of carbon-carbon three key; Such molecular arrangement has formed lubricating effect; Thereby guarantee under higher colorant concentration prerequisite, effectively reduce and spray resistance.
Below in conjunction with embodiment the present invention is described further, but and does not mean that limitation of the scope of the invention.
