Description

A kind of ultraviolet curing quick-drying waterproof ink and preparation method thereof

technical field

The invention relates to an ink and a preparation method thereof, in particular to an ultraviolet curing quick-drying waterproof 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. The photoinitiator in UV ink is a compound that is easily excited by light. After absorbing light, it is excited into a free radical, and the energy is transferred to the photosensitive molecule or photocrosslinking agent, so that the UV ink undergoes a photocuring reaction. At present, UV ink has become a relatively mature ink technology, and its pollutant discharge is almost zero. In addition to not containing solvents, UV inks also have the advantages of not easy to paste, clear dots, bright and bright ink colors, excellent chemical resistance, and low consumption.
