Abstract

The present invention relates to a UV metal printing ink and a preparation method thereof. The UV metal printing ink contains, by weight, 22.6% of chlorinated modified polyester acrylate, 15-25% of an adhesive force promoter, 5-10% of an active monomer, 7% of a composite photoinitiator, 35-50% of a metal pigment, 0.2% of a scratch-resistant auxiliary agent, and 0.2% of a polymerization inhibitor, wherein the active monomer is one selected from tri(propylene glycol) diacrylate, trimethylolpropane triacrylate and neopentyl glycol diacrylate or a composition comprising tri(propylene glycol) diacrylate, trimethylolpropane triacrylate and neopentyl glycol diacrylate. The present invention further provides a preparation method for the UV metal printing ink. With the UV metal printing ink, the direct adhesive force with the substrate can be enhanced.

Description

technical field [0001] The invention relates to an ink and a preparation method thereof, in particular to a UV metal ink and a preparation method thereof. Background technique [0002] The metal pigments in the formulation of ultraviolet (UV) metal inks can promote the polymerization of UV oligomers and reactive monomers. Therefore, UV metal inks are prone to gelation during storage. [0003] In order to avoid the above-mentioned problems, the prior art usually adds nitrocellulose with a low degree of polymerization to the formulation to improve the storage time of the ink. [0004] However, although increasing the content of nitrocellulose with a low degree of polymerization can prolong the gelation time, the adhesion of the ink film to the substrate tends to decrease with the increase of nitrocellulose content. SUMMARY OF THE INVENTION [0005] In view of the above situation, it is necessary to provide a UV metal ink with enhanced adhesion and a preparation method there...
