Embodiment 1

[0028] The light guide plate ink is prepared according to the composition ratio (mass percentage):

[0029] Urethane Acrylate 15%,

[0030] Polyester acrylate 50%,

[0031] Mix reactive diluent 15%,

[0032] Light reflective functional filler 15%,

[0033] Liquid paraffin 0.5%,

[0034] Dispersant 0.5%,

[0035] Photoinitiator (1173) 4.0%.

[0036] The preparation method comprises adding the above-mentioned components into a stirring device according to the formula ratio, and then grinding on a grinder until the particle size is 1-5 μm, and then packing.

[0037] Effect: The ink has excellent brilliance, the adhesion to acrylic is grade 1, the ink has good separation and release, and the curing time is 15 seconds.

Embodiment 2

[0039] The light guide plate ink is prepared according to the composition ratio (mass percentage):

[0040] Urethane Acrylate 20%,

[0041] Polyester Acrylate 40%,

[0042] Mix reactive diluent 10%,

[0043] Light reflective functional filler 26%,

[0044] Liquid Paraffin 1.0%,

[0045] Dispersant 0.5%,

[0046] Photoinitiator (1173) 2.5%.

[0047] The preparation method includes adding the above-mentioned components into the stirring device according to the formula ratio, and then grinding on the grinder until the particle size is 1-5 μm, stopping the grinding and packaging.

[0048] Effect: The ink has excellent brilliance, the adhesion to acrylic is grade 1, and it is easy to dry (good ink separation and release). The drying time is 15 seconds.

Embodiment 3

[0050] The light guide plate ink is prepared according to the composition ratio (mass percentage):

Abstract

The invention discloses UV solidified light guide plate printing ink which comprises the following components in percentage by weight: 15-30 urethane acrylate, 30-50 polyester acrylic resin, 10-15 hybrid reactive diluent, 15-26 light reflecting functional fillers, 0.5-1.5 liquid paraffin, 0.5-1 dispersants and 2.5-4 photoinitiators. The UV solidified light guide plate printing ink has the advantages of good balance performance, good pigment wettability, good leveling property, high adhesion, high brilliance, uniform reflection, no baking, quick curing speed, environment protection and no deformation of light guide plates, and can be used for liquid crystal displays, ultra thin light boxes, medical film viewers, computer luminous keyboards, LED light-emitting screens, mobile phone backlight sources, and the like.

Description

technical field [0001] The invention belongs to an ink, in particular to a UV curing light guide plate ink. Background technique [0002] The light guide plate ink is an important part of the backlight module of the light guide plate. When used, the ink is printed into reflective points through screen printing technology, and the original point light source is converted into a surface light source; the entire light guide plate emits light evenly and has consistent brightness. Purpose. [0003] Currently used ink is solvent-based, for example, patent (200510048683) and patent (99813332), its disadvantage is that the solvent contained in the ink is easy to volatilize, pollute the environment, affect the health of printing workers, poor environmental protection, and curing speed Slow, low luminance, poor luminous uniformity, low adhesion, low production efficiency, it is difficult to meet the requirements of environmental protection and production efficiency in the field of el...
