Abstract

The invention relates to high-adhesion LED-UV piezoelectric spray printing ink and a preparation method thereof. In order to solve problems in the prior art, a technical scheme of the high-adhesion LED-UV piezoelectric spray printing ink is as follows: a polyurethane-acrylate resin system is adopted; the ink is prepared from the following components in percentage by weight: 8%-30% of pigment typepaste, 5%-20% of polyurethane-acrylate resin, 5%-16% of a photoinitiator, 30%-50% of an acrylic acid reactive monomer solvent or oligomer, 0.5%-4% of a polymerization inhibitor and 0.5%-2% of a surfactant, wherein the pigment type paste contains sub-micron pigment. The ink is adaptable to various industrial-grade nozzles, and has high adhesion, high extensibility and high bending performance whensprayed on the surfaces of various soft and hard materials.

Description

technical field [0001] The invention relates to a jet printing ink, in particular to a LED-UV piezoelectric jet printing ink with high adhesion and a preparation method thereof. Background technique [0002] The development of inkjet technology is changing with each passing day, and inkjet printing is widely used in daily life. At present, in the industrial application of large-format jet printing, it is mainly divided into the following areas: [0003] 1.
