preparation example Construction

[0038] The present invention also provides a method for preparing LED UV offset printing varnish, wherein the LED UV offset printing varnish is the LED UV offset printing varnish as described in any one of the above embodiments. As another example, the preparation method includes the following steps:

[0039] S110: mixing the UV monomer and the photoinitiator, and dissolving the photoinitiator in the UV monomer to obtain a first mixture;

[0040] S120: Mix trifunctional urethane acrylate, difunctional epoxy resin, hexafunctional urethane resin, tetrafunctional polyester resin, active amine and additives to obtain a second mixture;

[0041] S130: Mix the first mixture and the second mixture evenly, and after grinding, obtain the LED UV offset printing varnish.

[0042] The first mixture and the second mixture are uniformly mixed, and the final grinding operation is performed to obtain the LED UV offset printing varnish with uniform fineness.

[0043] The LED UV offset printin...

Abstract

The invention discloses an LED UV offset print gloss oil and its application in an intelligent card domain or a package paper domain. The LED UV offset print gloss oil is prepared from, by mass, 28-35parts of trifunctional urethane acrylate, 2.8-4.1 parts of UV monomer, 4.5-6.5 parts of photo-initiator, 2.5-3.5 parts of dual-functional epoxy resin, 37-42 parts of hexa-functional polyurethane resin, 9-14 parts of tetra-functional polyester resin, 1-2 parts of active amine, and 3-6 parts of assistant. The LED UV offset print gloss oil is applicable to the LED UV cold light source, and featuredby low odor, excellent wear resistance and folding resistance, good flatting property and smooth property, quick curing speed, and extremely high gloss; moreover, the LED UV offset print gloss oil hasrelatively low contraction rate during the curing process; therefore, the LED UV offset print gloss oil can be applied to thin printing material suck as a PVC material.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a LED UV offset printing varnish and its application in the field of smart cards or packaging. Background technique [0002] UV offset varnish is an emerging printing ink in recent years. It mainly changes the ink from liquid to solid in an instant under the irradiation of ultraviolet rays of a certain wavelength to complete the drying process. [0003] With the development of science and technology, the speed of UV offset varnish printing is getting faster and faster, and the printing materials are getting thinner and thinner. Currently used UV offset printing varnish, in the curing process, the UV light source used is usually a heat light source, the heat light source generates more heat, and more heat is easy to damage thinner printed materials and heat-sensitive printed materials. In addition, the energy consumption of the thermal light source is relatively large. Contents of...
