Description

A kind of UV curable ink and preparation method thereof

Technical field

The present invention relates to a kind of ink and preparation method thereof, particularly a kind of UV curable ink and preparation method thereof.

Background technology

Ultraviolet light polymerization (UV) ink refers under uviolizing, utilizes the UV-light of different wave length and energy to make ink film forming and dry ink.The curing mechanism of UV curable ink is, the light trigger in system directly or indirectly absorbs after ultraviolet luminous energy, from ground state transition to excited singlet, alters and jump to excited triplet state between being; After excited singlet or triplet state experience unit molecule or bimolecular chemical action, the biologically active fragment that generation can trigger monomer polymerization, these fragments can be free radical, positively charged ion, negatively charged ion or ion free radical.Utilize different UV spectrum, can produce different-energy, the monomer polymerization in different ink vehicles is become to polymkeric substance, so the look film of UV ink has good machinery and chemical property.The major advantage of UV ink has: (1) is without solvent; (2) rate of drying is fast, and power consumption is few; (3) good luster, bright in luster; (4) water-fast, resistance to solvent, wear resisting property is good.In UV ink, light trigger is a kind of light activated compound that is subject to, and after absorb light is shone, is excited into free radical, and energy is transferred to photosensitivity molecule or photocrosslinking agent, makes UV China ink that photocuring reaction occur.UV China ink has become a kind of more ripe ink technology at present, and its pollutant emission is almost nil.Except not containing solvent, UV China ink is also just like being difficult for scumming, and site is clear, the bright-coloured light of mass colour, the advantage such as chemical resistance is excellent, low-consuming.
