Description
Technical field
The present invention relates to technical field of ink, more particularly to a kind of heat-sensitive variable colour microcapsules UV light-curable inks and its preparation
Method.
Background technology
Thermo colour is that under uniform temperature and pressure, chemical breakdown reaction occurs, and becomes new material, so as to embody
Different colours.Under moist room temperature or slightly higher temperature, storage thermo colour easily quick thermo colour occurs in the prior art
Fade, and it is cumbersome in making thermo colour technique, and general formula uses solvent, it is big for environment pollution.It is made into molten
Based ink has little significance, and is made into paste ink and then there is the phenomenons such as bad dispersibility, color developing effect difference, and this is industry
Interior long-term insurmountable technical barrier.
UV ink is one kind of printing-ink, is, using the ink of ultraviolet curing, to be different from natural drying, heating
Baking and curing, with quick solidifying, color change is small the characteristics of.At present in the print such as China's silk-screen printing, intaglio printing, flexographic printing
Swiped through journey largely uses solvent, the VOCs that ink is come out when printing is dried to account for quantity of ink about 70%~80%, VOCs and lead to
Cross breathing in vivo to cause damage human liver and nervous system into one, greatly danger is brought to printing worker and nearby residents
Evil.Occur emerging water-based ink in recent years, but because solvent is water, cause it to dry slow, dry incomplete, it is limited always
Development, is difficult to replace UV ink in a short time.
By the colour developing composition microencapsulation of thermo colour, temperature-sensitive microcapsules UV light-curable inks are made into, in industry
Inside belong to pioneering.Temperature-sensitive microcapsules UV light-curable inks solve the problems, such as that thermo colour pollution is big and storge quality is poor, temperature-sensitive
Microcapsules UV light-curable inks use ultraviolet light polymerization, with rate of drying it is fast, anchor effect is good, site is clear, water-fast, resistance to molten
The advantages of agent, good wearability, and VOCs discharges almost nil, good environmental protection, the scope of application is wider, with application valency higher
Value.
