Description
Technical field
The present invention relates to a kind of ink and preparation method thereof, be specifically related to a kind of dye ink-jet ink and preparation method thereof.
Background technology
Common aq. type dye ink-jet ink is the ink of molecular level CL, this ink is composite solution completely, during for spray ink Printing, the probability of spanishing head is very little, be easy to after air brushing by absorbed, chromatogram is complete, beautiful in colour, well arranged and price is also low than pigment ink, therefore the aq. type dye ink is mainly used in indoor document, picture and the digital textile stamp that does not need prolonged preservation now; Such as printing the purposes such as picture, making color spray business card.But, its shortcoming is not water-fast, chemical-resistant reagent not, and because dye molecule decomposes under uviolizing very soon, cause outdoor ultraviolet ray lower use just to have in one month obviously fade, thereby affected its application in life, fields such as prolonged preservation file, large-scale outdoor advertising.Therefore need to improve especially the performance of water base property dye ink-jet ink.
Select high Weather-proof dye can improve the light fastness of dye ink-jet ink, thereby extend the duration of service of aq. type dye ink-jet ink product.Add in addition ultraviolet screener, can absorb and the reflecting part ultraviolet ray, also can improve the light fastness of ink.Also the handlebar water-based dye ink is printed on the coating media of special facture, also can improve the working life of aq. type dye ink product.It is reported, some aq. type dye inks adopt high Weather-proof dye, are printed on the photo paper by special facture, and indoors preservation period can reach 50-100 even 200 years, can keep more than 1 year under the ultraviolet ray out of doors and obviously not fade.As seen, selecting high Weather-proof dye and UV light absorber as the component of aq. type ink for ink-jet print, is useful, can significantly extend the duration of service of ink-jet products.This water-based dye ink is mainly used in printing the photograph that specific coatings is arranged of permanent preservation period now because cost raises.This aq. type dye ink is used for outdoor air brushing, because this ink for ink-jet print not water-fast not chemical-resistant reagent still.
Outdoor air brushing is main solvent-based inks and the water-base pigment ink of using now.Solvent-based inks is because carrier is organic solvent, and is also fast light water-fast although duration of service is long, can produce in manufacturing and use procedure and pollute, and environment is had destruction; Organic solvent is also very high with respect to the cost of water simultaneously.The aq. type paint ink is a kind of aaerosol solution or is half solution powdery ink, and due to the waterproof of pigment own, its water tolerance is strong, also is not easy by ultraviolet light degradation, also can keep out of doors the sign that significantly do not fade more than a year duration of service.But the paint ink milling time is long, complex procedures; Therefore most paint ink all can make remained on surface look material; Print on the paper that glazed paper etc. has an even surface and to print glossiness image; And the easy layering of paint ink, precipitation are preserved unstable; The pigment colorant chromatogram is incomplete, and color is bright-coloured not, and transparency is bad; The manufacturing cost of paint ink is higher, and price is also expensive than dye ink, and its price differential is up to more than two to four times.In view of above factor solvent-based inks and aq. type paint ink also Shortcomings part.
Can solve the performance of water-fast, the chemical-resistant reagent of aq. type dye ink-jet ink, to realize the significantly lifting of aq. type dye ink-jet ink quality product? also make the aq. type dye ink can realize the field that the existing aq. type dye inks such as prolonged preservation file, outdoor air brushing can not be used?
Summary of the invention
Applicant of the present invention finds by various materials, various experiment, adds modified polyurethane emulsion and can make the printout of aq. type dye ink-jet ink have the performance of water-fast chemical-resistant reagent in the water-soluble dye ink for ink-jet print.Modified polyurethane resin is water miscible when emulsion state, can fully mix each component and the modified polyurethane resin emulsion of dye ink; Modified polyurethane resin emulsion has filming function, forms a skim after parching on medium, the various components of dye ink are coated in film, so aq. type dye ink-jet ink has obtained the performance of water-fast chemical-resistant reagent.
Modified polyurethane resin emulsion also has cementability, the product that prints has rub resistance, by bonding effect, ink is bonded on various media simultaneously, so modified polyurethane resin dye ink-jet ink can be printed on various without on coating and non-print coating media.As lamp house cloth, lantern slide, plastic cloth, enamelled paper, tobacco and wine wrapping paper, waterproof cloth, glass, ceramic tile.
Modified polyurethane resin emulsion absorbs ultraviolet effect in addition, and the ultraviolet ray that dyestuff is accepted under the coating of resin molding reduces, and light fastness obviously strengthens, and the product of printing also extends duration of service; The film that modified polyurethane resin forms has also completely cut off the environment of dyestuff generation chemical reaction, makes dyestuff avoid the invasion and attack of water and ozone, has also extended product duration of service.Simultaneously, can avoid dyestuff and UV light absorber to drop because rainwater drenches, dye coloring agent and UV light absorber are more permanent duration of service; The formed film of ink system is difficult for being destroyed by external environment.
Modified polyurethane resin emulsion parches rear very transparent, does not affect the toner color development, and the surface also has the performance of high light, so the ink product appearance has the effect of high light, and is more attractive in appearance.
Parameter from the spray ink Printing key: surface tension, viscosity, specific conductivity, pH value, added modified polyurethane resin emulsion very little less than impact or impact on ink-jet dye ink physical and chemical index, the modified polyurethane resin emulsion particulate can pass through printhead in the 50-200 nanometer.
In application number is 201010264526.2 Chinese patent, proposed water-soluble dye and or solvent dye 0.2-12%, modified polyurethane resin emulsion (solid content) 13.5-49.8%, UV light absorber 0.01-1% can be used as the scheme of ink for ink-jet print.In this scheme, the modified polyurethane resin emulsion addition is too much.The experiment discovery, the product of printing soaks the some months ink and does not also obviously fade in water, substantially exceed the practical situation of environment for use in life.The water tolerance of outdoor air brushing product can withstand one month (plum rain season) continuously rainwater to drench environment colour-fast, be exactly suitable.This will decide according to the actual environment that the dye ink-jet ink is used the addition of modified polyurethane resin emulsion.Experiment finds, modified polyurethane resin emulsion (solid content) addition in the situation that the ink gross weight than 1-13%, aq. type ink for ink-jet print product still has the performance of water-fast chemical-resistant reagent.The modified polyurethane resin emulsion addition is too much, and manufacturing cost is improved, and this uses to product promotion and makes troubles.Simultaneously, the modified polyurethane resin emulsion addition is too much, brings difficulty can for the storage stability of ink, printing fluency.Consider between above comprehensive condition, remodeling ester-polyurethane resin emulsion addition can suitably reduce.
The purpose of this invention is to provide a kind of shortcoming that overcomes simultaneously existing dye ink and paint ink, have the aq. type dye ink-jet ink of excellent properties.Its excellent properties shows:
1: significantly extend aq. type ink-jet dye ink product duration of service.
2: stability in storage is good, printing is smooth.
3: have water tolerance, chemical resistant properties, resistant of high or low temperature, rub resistance, ageing resistance, high light, color is transparent and reductibility is good.
