Description
Technical field
The invention belongs to UV cured printing ink preparing technical fields, more particularly to a kind of hyperbranched resin base UV cures ink-jet oil
Ink and its preparation method and application.
Background technology
UV ink jet printings are a kind of new technologies to grow up at the end of the 20th century, it combines ink-jet printing technology and UV cures
The respective advantage of technology, existing ink-jet printing technology using and operational facility, also have UV curing technologies economically, skill
Advantage in art and in environmental protection：First, UV jetted inks will not dry up face on the print head, avoid ink setting and be bonded in spray
Cause serious problems in mouth, it is not required that the insoluble substance in cleaning sprayer, and cleaning sprayer is in other ink-jet technologies
The problem of common；Secondly, ink-jet products have prominent light resistance and product resistance, and curing rate of drying is quick, and spray
Organic volatile is free of in the component of black ink.Therefore it is that one kind that ink develops becomes that UV jetted inks, which substitute solvent-based ink,
Gesture, China is every year because of the VOC up to hundreds of thousands tons being discharged into using solvent-borne type ink used for plastic in air, if using UV ink-jets oil
Ink substitutes solvent-borne type ink used for plastic, and tremendous contribution will be made to reducing China's VOC emission.
The main reason for influencing the development of UV jetted inks, its existing ink-jet apparatus derived from a few external producer, price
Costliness, and restricted be subject to its main raw material(s) resin property and price, it is mainly few by foreign countries to result in current UV jetted inks
Several several chemical industry giants are monopolized.Wherein design it is low it is viscous, surface tension is suitable, high curing reactivity, strong mechanical performance UV resins

Property, corrosion resistance etc. and decisive influence is suffered to the cured sensitivity of UV.The more UV of research cures pure third at present
Appearance of film, hardness and the chemical-resistance of alkene acid ester resin are often not satisfactory, its reason is exactly matrix resin chain structure list
One, viscosity is high, and solid content is low, and functional group's degree of unsaturation and UV activity of curing reaction are low, and curing performance, which is not enough to reach, is expected to want
Ask.Hyperbranched resin because of its unique three-dimensional spherical multiple-branching construction, and with peripheral degree of functionality is high, reactivity by force, viscosity it is low
Etc. numerous characteristics, UV inkjet ink systems can be applied to, to alleviate the contradiction between linear systems large arch dam and low viscosity, carried
The performance of whole UV curing systems is risen, but since the structure design of hyperbranched resin has certain difficulty, at present can be really real
The hyperbranched resin of existing industrialization is also seldom.
