Description

A kind of one-time printing ultraviolet light curing pearlescent ink and preparation method thereof

technical field

The invention relates to an ink and a preparation method thereof, in particular to a one-time printing ultraviolet light curing pearlescent ink and a preparation method thereof.

Background technique

Ultraviolet curing (UV) ink refers to the ink that uses ultraviolet light of different wavelengths and energies to form a film and dry the ink under ultraviolet radiation. Using different ultraviolet spectra, different energies can be generated to polymerize monomers in different ink binders into polymers, so the color film of UV ink has good mechanical and chemical properties. The main advantages of UV ink are: (1) No solvent is used; (2) Fast drying speed and less energy consumption; (3) Good gloss and bright colors; (4) Water resistance, solvent resistance, and good wear resistance. UV curable pearlescent ink is a kind of screen printing ink, which forms colorful pearlescent effect after being irradiated by ultraviolet light with specific wavelength. Ink, its curing speed and adhesion are excellent. The currently used ones are generally solvent-based, polluting the environment, affecting the health of operators and other disadvantages, and the drying is natural drying, which takes more than ten minutes, and the production efficiency is low.
