Composition of white ink for ink-jet marking using zinc sulfide power and fabrication method thereof

摘要

A method for producing an ink-jet marking white ink composition according to the present invention comprises a steps (S10) of preparing raw ingredients such as 10-15 wt% of a UV hardening acrylate resin, 5-30 wt% of a multifunctional group acrylate functional monomer, 5-10 wt% of a UV photoinitiator, 30-40 wt% of a unifunctional group acrylate functional monomer, and 10-20 wt% of zinc sulfide particles based on the total composition; a first mixing step (S20) of obtaining a first mixture by mixing the UV hardening acrylate resin, multifunctional group acrylate functional monomer, and the zinc sulfide particles and obtaining a separate second mixture from the first mixture by mixing the UV photoinitiator and the unifunctional group acrylate functional monomer; and a second mixing step (S30) of mixing the first mixture and the second mixture.
