Problems solved by technology

Most of the existing technologies reduce the resin content in the inkjet, and dilute the ink with a large amount of active monomers in order to reduce the viscosity, but at the same time it also reduces the adhesion, high temperature resistance and other properties

[0044]

[0045] The preparation method of above-mentioned UV-LED inkjet printing character ink, comprises the following steps:

[0046] (1) Mix the dispersing resin, 10-30% monomer, dispersant, and titanium dioxide, grind it with a grinder until the pigment particle size D50 is less than 300nm, filter to obtain a white nano-color paste, and set aside;

[0047] (2) Dissolving the photoinitiator in the remaining monomers, mix well, and set aside;

[0048] (3) Mix modified epoxy resin, latent curing agent, monomer dissolved with photoinitiator, white nano-color paste, adhesion promoter, auxiliary agent, stir evenly, and then filter through a 1 micron filter membran...

Abstract

The invention discloses UV-LED ink-jet printing character ink and a preparation method thereof. The ink is prepared from the following raw materials in percent by weight: 5-18% of modified epoxy resin, 4-8% of dispersion resin, 0.1-2% of a latent curing agent, 55-70% of a monomer, 8-15% of titanium dioxide, 6-8% of an initiator, 0.1-5% of an adhesion promoter and 0.1-5% of an assistant. The ink is suitable for UV lamp curing, is especially suitable for UV-LED lamps of which the wavelengths are 365nm and 395nm, and has the characteristics of low viscosity, good adhesive force, high temperature resistance, yellowing resistance and good hardness.

Description

technical field [0001] The invention belongs to the technical field of ink for circuit boards, and in particular relates to a UV-LED inkjet printing character ink and a preparation method thereof. Background technique [0002] PCB (Printed Circuit Board) is a printed circuit board, which is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. Usually, characters are printed on the PCB board for subsequent installation inspection or maintenance. Traditionally, screen printing is used to print characters on the circuit board. This printing method not only has high cost, many processes, and a long cycle, but the printed characters will also appear blurred, ghosting, and poor graphics clarity and fineness. and other defects. Moreover, this printing ink needs to be diluted with an organic solvent, and has VOC and waste water discharge, which pollutes the environment. [0003] The emergence of...
