Description
Technical field
The present invention relates to the preparation method of a kind of anti-UV dye ink and this ink.
Background technology
Inkjet technology has two kinds of thermal bubble type and piezoelectric types, and thermal bubble type gasifies the ink through spray orifice rapidly through heating, and air bubble expansion just can be extruded to a certain size, with receivers such as the state ejected towards paper of atomic small droplets, clothes.Piezoelectric ink jet is printed through the piezoquartz high speed vibration, and ink droplet jet is gone out.At present, the ink that uses in the spray ink Printing field consists predominantly of: at least a colorant (dyestuff or pigment) provides the color performance of ink; Vehicle (water or organic solvent) is as solvent; Wetting Agent for Printing Inks; Tensio-active agent; The PH buffer reagent; Sanitas; Sequestrant; Sterilant.Ink with vectorial different, can be combined into four types of aqueous dye ink, aqueous pigment ink, solvent dye ink and solvent-borne type paint inks according to colorant.
The organic solvent high volatility that solvent-based inks is used, smell is heavy, environmental issue is serious, in some field such as the screen painting industry progressively replaced by aqueous ink, be not the developing direction of industry.Because water-base ink is cheap, safe, pollution-free, becomes main product in the ink-jet field.In water-base ink, the pigment in the paint ink exists with graininess, with dispersion agent it is dispersed in the ink system, and particle can sedimentation take place change slowly greatly, stops up printhead; On the other hand, the colour vividness of paint ink is also not as good as dye ink, the price of dye ink be its 1/4th to 1/5th.Therefore, aqueous dye ink is the most widely used ink of spray ink Printing industry, is widely used in desktop printing, the air brushing of large format machine, weaving digit printing etc.
Though aqueous dye ink accounts at aspects such as color, price, stability and has great advantage, on water-repellancy, anti-UV (ultraviolet resistance) performance, not as aqueous pigment ink.How to improve these two kinds of performances of dye ink, the weather resistance that prolongs its printed product is preserved, and is the direction of numerous producers and technician's research in the industry.
At present, the anti-UV performance of raising dye ink has following method:
1, through changing dye property, some group of grafting on the molecular structure of dyestuff is like grafting halogen in dyestuff, be grafted to the carboxylic methylsulfonyl on the dye molecule.Though this can improve the performance of its ultraviolet resistance, the form and aspect of ink can change, or printing effect is darker, or colorimetric purity is bad.
2, in ink, add ultraviolet light reagent, for example USP U.S6176909.In ink, directly add ultraviolet light reagent, can improve to its photostabilization, but the reaction of ultraviolet light reagent and light is a successive and irreversible.Ultraviolet light reagent constantly reacts with light fast, and until ruing out of, its raising to the ink weather resistance is of short duration.
3, also there is document to mention, contains the way of the microcapsule of ultraviolet absorbers, the consisting of of its microcapsule: urea-formaldehyde resin and ultraviolet absorbers through adding.Ultraviolet absorbers is generally oil-soluble, the bad control of capsule particle size of adopting this method to produce, and particle size generally is controlled at below 1 micron in the jetting ink, useful capsule rate is low.On the other hand, urea-formaldehyde resin is met soda acid and is decomposed easily, and weathering resistance is poor.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes prior art, and a kind of cheapness, stable performance, bright in luster and anti-UV dye ink that weather resistance is strong are provided.The present invention also provides a kind of preparation method who prepares above-mentioned anti-UV dye ink, utilizes this method can make anti-UV dye ink easily.
