Problems solved by technology

Although the traditional mercury lamp type UV curing equipment and the traditional mercury lamp type UV curing coating ink are cheap in the Chinese market, due to the high maintenance cost and large power consumption of the traditional mercury lamp type UV curing equipment, large carbon emissions and UV The rapid attenuation of the light intensity of the mercury lamp leads to frequent replacement of the ultraviolet mercury lamp, the rise of the surface temperature of the irradiated components leads to the deformation of the heat-sensitive substrate, the large volume leads to a large space occupation, a large amount of ozone is produced

Abstract

The invention relates to the field of ink and preparation processes thereof, in particular to a light-emitting diode (LED)-ultraviolet (UV) area light source curing outdoor silk screen printing ink composition which is particularly suitable for silk-screen printing for outdoor advertisements and suitable to be used by semiconductor excitation UV area light source curing equipment. The ink composition comprises 25 to 55 weight percent of LED-UV resin and 10 to 25 weight percent of LED-UV monomer, wherein the LED-UV resin is one or mixture of amine modified epoxy acrylate resin, amine modified polyester acrylate resin, and amine modified polyether acrylate resin, and the LED-UV monomer is one or mixture of 2-(ethyoxyl vinyl) ethyl acrylate monomer, trimethylolpropane triacrylate monomer, and dipentaerythritol hexaacrylate monomer. Compared with the prior art, the ink composition has the advantages of saving energy, along with high curing speed, high film coating performance, high glossiness and environment-friendliness and the like.

Description

technical field [0001] The invention relates to the field of ink and its manufacturing process, in particular to an LED-UV surface light source photocuring outdoor screen printing ink composition and its method. Background technique [0002] As we all know, UV curing equipment and UV curing coating inks have undergone continuous research and development and improvement. The ultraviolet light production process with mercury lamp irradiation as the mainstream has been adopted for a long time. Although the traditional mercury lamp type UV curing equipment and the traditional mercury lamp type UV curing coating ink are cheap in the Chinese market, due to the high maintenance cost and large power consumption of the traditional mercury lamp type UV curing equipment, the carbon emissions are large and the UV The rapid attenuation of the light intensity of the mercury lamp leads to frequent replacement of the ultraviolet mercury lamp, the rise of the surface temperature of the irr...
