Abstract

The invention provides ultraviolet-light-cured glass transparent ink, which can be applied cooperatively with UV painting. The ultraviolet-light-cured glass transparent ink comprises the following components by weight percent: 55 to 80% of mixed UV resin, 5 to 10% of mixed ultraviolet light trigger, 0.1 to 0.5% of polymerization inhibitor, 10 to 30% of UV active monomer, 1 to 3% of adhesion promoter, 0.5 to 1% of defoamer and 0.2 to 0.8% of flatting agent. The invention further provides a preparation method for the ultraviolet-light-cured glass transparent ink. The ink obtained through the raw materials and the preparation method has the advantages of high curing speed, short production period, simpleness and convenience in operation and no solvent contamination, can be painted directly on the surface of a glass substrate, has a high curing speed and high transparency and is well matched with a UV-painted ink layer. The edges of patterns are flat and clear and not etched, and cannot be corroded by UV painting ink, and be well adapted to painting on a UV-painted surface. In addition, the ultraviolet-light-cured glass transparent ink has the characteristics of environmental friendliness, weak odor and few VOC residues.

Description

technical field

[0001] The present invention relates to a UV-curable glass transparent ink and a preparation method thereof, in particular to a UV-curable glass transparent ink compatible with UV inkjet printing and a preparation method thereof, wherein the UV-curable glass transparent ink is matched with the UV inkjet ink, Excellent decorative effects can be achieved on the surface of glass substrates. Background technique

[0002] As a large category of printing consumables, compared with plastic (PP, PVC, PET, PMMA, etc.) substrates, glass substrates have the advantages of high transparency, good mechanical strength, and good weather resistance. , The production cost of glass is also lower than that of plastic substrates. However, due to the low surface energy of glass, the ink is not easy to adhere, which has limited its application in the printing industry for a long time.

[0003] With the development of science and technology, ink manufacturers adopt new synthetic r...
