Description

Preparation method of vehicle capable of rapidly drying water-based UV ink
Technical Field
The invention belongs to the technical field of water-based UV ink processing, and particularly relates to a preparation method of a binder capable of quickly drying water-based UV ink.
Background
Most of current ink manufacturers consider that UV ink has stronger advantages than solvent-based ink in the aspects of environmental protection, health and safety, does not contain heavy metal, has lower discharge amount of VOC and volatilization amount of harmful solvent, does not need to use too much irritant cleaning agent in the processes of printing, screen cleaning and recovery, has high curing efficiency, consumes less energy in UV drying compared with a heat energy dryer used by solvent-based and water-based ink, avoids the use of an additive which is easy to cause pollution to NVP or V-Pyrol, can adapt to green materials of modern printing, is superior to other ink in terms of high-speed printing and environmental protection, and has more excellent performances of short period, instant drying and stability, strong color matching capability, small printing ink amount and the like, so that the UV ink is widely applied in the printing industry.
The drying principle of the UV printing ink is that ultraviolet irradiation is utilized to decompose molecules of photosensitive materials (photoinitiator) in the printing ink to form high-activation atoms or atomic groups, unsaturated bonds contained in resin in the printing ink are initiated to break to generate a series of chain reactions through free radical polymerization, and finally the purposes of crosslinking, polymerization, curing and drying of the molecules are completed, in the UV ink, the most important component is the photocurable resin in the binder, and the difference between the photocurable resin and the general ink binder resin is that a large number of double bonds or triple bonds are present in the photocurable resin to rapidly cause a crosslinking curing reaction, giving the UV ink photocurable properties, and the variety of the photocurable resin is large, also vary in manufacture, but the overall requirement is to obtain a higher relative molecular mass and to retain some double bonds; therefore, the resin with higher photocuring rate and larger molecular weight is the main consideration for selecting the UV ink binder resin, but the photocuring resin has more unsaturated bonds and higher activity, is easily oxidized by oxygen in the air to react during resin curing, reduces the curing speed, and has poorer flexibility of an ink film after curing. The water-based UV ink has the advantages of both water-based ink and UV ink, and has the characteristics of no stimulation, no pollution, safety and the like compared with common UV ink, so that the research on the environment-friendly UV ink is more suitable for the environmental protection requirement of the current society and the development of printing industry, but the problem of low ink drying speed is inevitably brought by using water as a solvent in the water-based UV ink, the printing speed is seriously influenced, and the problem is one of the difficulties encountered in the development process of the water-based UV ink.
