Abstract

In order to improve the curing speed of UV-LED inkjet ink, different types of prepolymers, monomers, photoinitiators were used to prepare ink, then the inks were cured under 365nm UV-LED illuminant to investigate their impact on curing speed. Co-photoinitiators were designed by formulation experiment and the content of photoinitiator was changed to make ink samples, after curing speed being tested, the photoinitiator and its content were determined which can obtain higher curing rate. In addition, the single-core, dual-core and quad-core UV-LED illuminant were used to cure the same ink and test their curing speed. The results show that the prepolymer, the structure of monomer, the content of photoinitiator and its light absorption, the parameters of illuminant all have a significant impact on UV-LED inkjet ink, the prepared inks match the illuminant can have higher curing speed.
