1. Light setting resin
Also called polymer, is a low molecular weight unsaturated functional polymer, it is the main film of ink material, its content is about 30% to 50%. Its performance directly affects the physical, chemical, printing suitability and printing performance of ink.
2. Active diluent
Monomer plays an important role in the reaction process, not only can regulate the viscosity of the solution, but also can be used as a material of the film, which has a great relationship with the final film formation performance, curing kinetics, polymerization degree and the film formation performance of the polymerization reaction. Its excellent properties are low viscosity and easy to dissolve.
3. Luminescence initiator
Add a trace of photopolymerization initiator in the ink, under the action of ultraviolet light, photoinitiator will absorb light quantum, decompose to produce free radical, cause unsaturated double bond polymerization, so that the interaction between polymer molecules to form a network, so that free radical loss of vitality, so that the chain length stop. By this time, the ink has solidified.
4. The coloring
Ultraviolet curing ink colorant is pigment. Under normal circumstances, the performance of coating mainly depends on the properties of coating. Including the stability of light, heat, climate, organic solvents and other factors, dispersity in the processing process, coloring, color collocation of the final product, etc. Pigment is an important factor affecting the color and optical properties of finished products, which directly affect the nature and dispersion degree of pigment, that is, the particle size. In the case of the same composition, the hue, coloring force and coverage force are related to the degree of dispersion.
5. Additives
In order to improve some properties of the product, it is often necessary to add appropriate leveling agent, plasticizer, polymerization inhibitor, wetting agent, defoaming agent, heat stabilizer, etc. It should be especially pointed out that the addition of these additives will cause aging and deterioration of the film, and affect the curing system to a certain extent.
