Description
Technical field
The present invention relates to a kind of cyan ultraviolet (UV) jetted ink for high-speed inkjet printing and preparation method thereof, its printable fabric is mainly paper, belongs to digital printing technologies field.
Background technology
The key advantages of UV curing technology is exactly not containing solvent, do not have VOC to discharge, avoid the impact that traditional solvent-borne ink brings environment, be considered to a kind of " green technology ", and instantaneous solidification can be realized, ink setting speed is higher than water-based or solvent type ink, but UV ink is mainly used in traditional mode of printing, such as offset printing, silk-screen etc.Ink jet printing is as the one of digital printing technologies, have non-impact transfer printing, simple to operate, to the advantage such as printable fabric is less demanding, the printing equipment that UV curing technology combines with ink jet printing is emerged, will strengthen the demand of corresponding UV jetted ink.
Existing patent proposes the jetted ink of multiple radiation-hardenable at present, but the application of these ink is only confined to air brushing, printing and dyeing, does not also reach the requirement of high-speed inkjet printing far away.
Summary of the invention
The invention provides a kind of novel cyan UV ink jet ink formulations and preparation method thereof.The research and development of this UV jetted ink for mode of printing be high-speed inkjet printing, its printable fabric is mainly paper, and in order to meet the requirement of high-speed inkjet printing, the physical and chemical performance of ink must meet the needs of relevant ink-jet printing apparatus.Because pigment is insoluble to system, the dispersiveness of granules of pigments in system and dispersion stabilization are one of key propertys, otherwise the blocking of shower nozzle can be caused, UV system is different from water and solvent, granules of pigments must can be dispersed in system and also keep the stable phenomenon of reunion that just can there will not be just can prevent from blocking shower nozzle, common water-based and solvent-based inkjet ink or for the grain diameter of the UV ink of air brushing, printing and dyeing generally more than 1 μm, and need to reach less than 0.5 μm for the UV ink of high-speed inkjet printing.On market, two kinds of topmost drop on demand ink jet technology are hot ink-jet and piezoelectric ink jet, the shower nozzle of different operating mode is different to the requirement of ink viscosity, water-based shower nozzle, solvent-borne type shower nozzle and UV shower nozzle can be divided into again according to ink type, the UV shower nozzle that SPECTRA and XAAR releases is applied to some extent on UV ink-jet printer, UV shower nozzle major part is piezo type, require higher to ink viscosity, be generally 20-30cP(25 DEG C).UV jetted ink is under the irradiation of UV-light, and each component in system reacts and solidifies, and requiring curing speed to be 30-50m/min(light source linear heat generation rate is 200W/cm).In ink jet printing, the injection of ink droplet and forming process will be subject to the impact of fluid physics attribute, jet constriction is the prerequisite that ink droplet generates, and surface tension is the chief motivation of jet constriction, therefore the surface tension of ink is the propulsion source that ink droplet sprays, affect net shape and the flight path of ink droplet, and even affect final reproduction quality, surface tension requirements is 20-35mN/m(25 DEG C).
