Abstract

The invention belongs to the technical field of light-guiding ink preparation, and in particular relates to a preparation method of light-curing light-guiding ink. The specific steps are: 1) Dissolve 25%-45% acrylic resin, 3%-10% stearic acid or stearate into 30%-45% mixed solvent of toluene and butanone under dark conditions 2) Continue to add 2% to 6% of anti-scratch additive, 8% to 18% of nano light guide powder, 1% to 5% of photoinitiator, and continue to stir for 10 to 20 minutes to prepare Obtain UV curable light guide ink. The light guide ink prepared by the invention has good screen printability, the acrylic resin has good flexibility after UV curing, and has good adhesion to the acrylic plate, and the ink can be improved while maintaining the flexibility by adding scratch-resistant additives. The hardness of the film, its pencil hardness can reach 2H. The preparation method of the invention has simple process, and the prepared light guide ink has good performance.

Description

technical field [0001] The invention belongs to the technical field of light guide ink preparation, and in particular relates to a preparation method of photocurable light guide ink. Background technique [0002] The light guide plate is an important part of the backlight module in the LCD panel. When using the light guide ink, the ink is printed into reflective points through the screen printing technology. When the light shines on each light guide point, the reflected light will diffuse to all angles , and then destroy the reflection conditions and emit from the front of the light guide plate, thereby converting the point light source into a surface light source, so as to achieve the effect of making the entire light guide plate emit light uniformly. [0003] Patent application number 201110213082.4 discloses a UV curing light guide ink and a light guide plate using the ink. The light guide ink includes components: cross-linking reaction between polyurethane acrylic resin...
