AI Technical Summary

Problems solved by technology

The thermosetting character inkjet ink that appeared later can meet the required performance requirements, but the curing speed of the thermosetting character ink is not fast enough, and the principle of energy saving and environmental protection cannot be realized
[0004] At present, there are also a small number of UV-curable character inks, but none of them can solve the problem of low durability of character inks.

Abstract

The invention provides ink-jet printing identifying printing ink. The ink-jet printing identifying printing ink comprises 5 to 15 parts of a hyperbranched urethane acrylate oligomer, 5 to 15 parts ofa polyfunctional group acrylic monomer, 5 to 10 parts of a photoinitiator, 30 to 50 parts of a diluent, 5 to 15 parts of a pigment and 0.1 to 5 parts of other accessory ingredients; the polyfunctionalgroup acrylic monomer comprises dipentaerythritolpentaacrylate, propoxy neopentyl glycol diacrylate and 3-hydroxy-2,2-dimethyl propyl-3-hydroxy-2,2-methyl propyl diacrylate. The ink-jet printing identifying printing ink provided by the invention has preferable acid and alkali resistance and yellowing resistance.

Description

technical field [0001] The invention belongs to the technical field of inkjet printing, and in particular relates to an inkjet printable marking ink. Background technique [0002] In recent years, with the higher requirements of the refined development of the electronics industry, circuit boards are required to be marked with serial codes or QR codes to achieve true traceability. Inkjet printing technology can greatly simplify the PCB production process by replacing traditional silk screen technology or laser technology, eliminating many PCB production facilities and expensive equipment, greatly shortening the production cycle, reducing costs, and more importantly, greatly saving energy. and water consumption, essentially achieving the fundamental purpose of energy saving and emission reduction. [0003] The character ink used commercially in the PCB industry consists of oligomers, monomers and solid fillers with a particle diameter of 5 μm. This ink cannot be used in inkje...
