Abstract

The invention relates to the technical field of printing ink for circuit boards, in particular to character printing ink of a UV-LED ink-jet printing flexible printed circuit board and a preparation method thereof. The character printing ink of the UV-LED ink-jet printing flexible printed circuit board is prepared from the following components in percent by weight: 5-15% of modified epoxy resin, 5-10% of dispersion resin, 1-5% of an organic boron complex, 1-5% of an active toughener, 8-15% of titanium dioxide, 50-65% of a monomer, 5-8% of a free radical photoinitiator, 1-3% of a cationic photoinitiator and 0.1-5% of an auxiliary agent. The active toughener is a long chain aliphatic compound containing a glycidyl ether group. The monomer is at least one of a monofunctional group monomer, abifunctional group monomer and a trifunctional group monomer. The character printing ink of the UV-LED ink-jet printing flexible printed circuit board is high in curing speed, low in viscosity, excellent in adhesive force, low in shrinkage, good in bending resistance, good in flexibility and good in jet printing performance.

Description

technical field [0001] The invention relates to the technical field of ink for circuit boards, in particular to a UV-LED inkjet ink for printing soft board characters and a preparation method thereof. Background technique [0002] Flexible circuit boards, also known as "soft boards", are printed circuit boards made of flexible insulating substrates. They have good flexibility and electrical properties, and can be bent, wound, and folded without deformation and damage to the circuit. It is used as the connector and carrier of some electronic devices such as small electrical appliances such as mobile phones. In the process of soft board processing, in order to ensure the quality and efficiency of the soft board, it is often necessary to print characters on the soft board. However, the current traditional printing method is mainly screen printing. This printing method has complicated steps, high cost, long printing cycle, poor printing effect, and also discharges a large amoun...
