Preparation method of UV hard gloss oil suitable for Ricoh printing head

Abstract

The invention belongs to the field of ink-jet printing, particularly relates to a preparation method of UV hard gloss oil suitable for a Ricoh printing head, aims to solve the problem that the toughness of existing UV hard gloss oil is difficult to improve in the preparation process, and provides the following scheme: the UV hard gloss oil is included and is prepared from the following componentsin percentage by mass: 40-60% of a reactive monomer, 0.3-2% of a leveling agent, 7-12% of an initiator, 6-25% of an oligomer and the balance being an active monomer; the oligomer is synthesized from 17-23 parts by mass of glycidyl tertiary carboxylic ester, 20-30 parts by mass of glycidyl methacrylate, 3-8 parts by mass of methyl methacrylate, 12-18 parts by mass of butyl methacrylate and 3-8 parts by mass of butyl acrylate. While the requirements of environmental objectives are met, the energy consumption can be reduced and no toxic or side effects are generated in the manufacturing and usingprocess, and the UV hard gloss oil does not irritate the human skin, and is an environment-friendly ink.

Description

technical field

[0001] The invention relates to the technical field of inkjet printing, in particular to a method for preparing UV hard varnish suitable for Ricoh print heads. Background technique

[0002] Generally speaking, the UV ink is cured before it can fully penetrate, and the film layer is mainly on the surface of the printing material. The adhesion between the ink and the printing material is smaller than that of solvent-based ink, etc., and the adhesion to some printing materials is still weak. needs improvement. The pigments used in solvent-based inks and UV inks are generally the same, but the solvent of solvent-based inks is partially dissolved into the printing material, and its colorant is actually mixed with the medium rather than attached to its surface. As a result, the pigments are better protected and the graphics are more durable. The ink droplets of UV ink stay on the surface of the printing material, although better fidelity can be obtained, but its ...
