Problems solved by technology

This is because ordinary UV inks often fail to complete curing after high-speed printing of more than 15,000 sheets / hour, or the surface is cured but the deep layer of the ink is not completely cured, resulting in printing quality problems such as sticking and scratching.

Abstract

The invention belongs to the technical field of ink, and in particular relates to quick-curing ultraviolet (UV) ink, which is prepared from the following component by weight percent: 30-60% of acrylicresin with 7-8 functional groups, 5-10% of rosin resin, 10-40% of a monomer, 5-10% of filler, 5-15% of a photoinitiator, 5-20% of pigment, 0.5-3% of wax powder, 2-10% of active amine, 0.5-2% of fumednano-silica and 1.0-5% of additives. Due to the cooperation of double initiators, the acrylic resin with the 7-8 functional groups as well as the other components, the quick-curing UV ink can be obtained; furthermore, the surface layer and the inner layer of the ink can simultaneously accept photons so as to be subjected to a cross-linking reaction and further cured at the same time.

Description

technical field [0001] The invention belongs to the technical field of inks, in particular to a fast-curing UV ink. Background technique [0002] As an efficient and environmentally friendly ink, UV ink is currently widely used in the printing and packaging industry. With the continuous improvement of high-speed printing technology, the printing speed of modern offset printing can reach more than 15,000 sheets / hour. The requirements in terms of curing speed are also getting higher and higher. This is because ordinary UV inks often fail to complete curing after high-speed printing of more than 15,000 sheets / hour, or the surface is cured but the deep layer of the ink is not completely cured, resulting in printing quality problems such as sticking and scratching. In order to better improve the printing quality and reduce the energy consumption of printing, the UV ink that cures the surface layer and the deep layer of the high-speed ink at the same time has been developed, whic...
