Problems solved by technology

However, most of the existing UV inks are dried on the surface due to the obstruction of light on the surface of the film layer, which affects the overall curing effect, and the adhesion and flexibility are insufficient, and the viscosity of the ink is too high, which is difficult to meet customer needs.

Abstract

The invention relates to the technical field of UV ink, in particular to UV ink and a preparation method thereof. The UV ink is prepared from the following raw materials in parts by weight: 50 to 70 parts of epoxy acrylate, 10 to 15 parts of polyester acrylate, 4 to 8 parts of polydiallyl phthalate, 3 to 5 parts of a photoinitiator, 2 to 3 parts of a photosensitizer, 15 to 25 parts of a reactive diluent, 5 to 10 parts of diatomite, 0.2 to 0.5 part of a defoaming agent, 1 to 2 parts of polyethylene wax, 2 to 4 parts of a dispersing agent and 0 to 20 parts of a coloring agent. Through the synergistic effect, the overall adhesiveness, the flexibility, the wear resistance and the curing effect of the UV ink are improved, and the viscosity is reduced.

Description

technical field [0001] The invention relates to the technical field of UV ink, in particular to a UV ink and a preparation method thereof. Background technique [0002] UV (ultraviolet curing) ink refers to the ink that uses ultraviolet light of different wavelengths and energies to polymerize the monomers in the ink binder into polymers to form a film and dry the ink under ultraviolet radiation. UV inks are also inks. As inks, they must have bright colors (except in special cases), good printability, and suitable curing and drying rates. However, most of the existing UV inks are dried on the surface due to the obstruction of light on the surface of the film layer, which affects the overall curing effect, and the adhesion and flexibility are insufficient, and the viscosity of the ink is too high, which is difficult to meet customer needs. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present i...
