preparation example Construction

[0017] The preparation steps of an anti-scratch UV curable light guide ink: take 30%-40% acrylic resin, 4%-8% anti-settling agent, 4%-8% coupling Dissolve the agent in 25%~40% organic solvent, stir at high speed, stirring speed 1500~2000rpm, stirring time 10~20 minutes; then add 3%~8% anti-scratch additives, 8%~15% nano-conductor Light particles, 1% to 5% of the photoinitiator, continue to stir for 10 to 20 minutes to prepare UV curable light guide ink.

[0018] Wherein, the nano light guide particles are selected from one or more of silica, glass powder or transparent resin particles, and have an average particle size of 30-50 nm.

[0019] Wherein, the coupling agent includes one or more of sodium hexametaphosphate, sodium tripolyphosphate or sodium polyacrylate.

[0020] Wherein, the scratch resistance auxiliary agent includes one or more of beeswax, organic wax, polyethylene powder, and polytetrafluoroethylene powder, preferably polyethylene powder.

[0021] Wherein, the photoinit...

Embodiment 1

[0024] Under dark conditions, take 35 grams of acrylic resin, 6 grams of organic montmorillonite and 8 grams of sodium hexametaphosphate dissolved in 25 grams of toluene solvent, stir at high speed, stirring speed 1500, stirring time 10 minutes; then add 8 grams of anti Scratch aid beeswax, 15 grams of silicon dioxide, 3 grams of photoinitiator dialkoxy acetophenone, and continue to stir for 10 minutes to prepare UV curable light guide ink.

Embodiment 2

[0026] Under dark conditions, take 30 grams of acrylic resin, 4 grams of organic montmorillonite and 6 grams of sodium tripolyphosphate dissolved in 40 grams of methyl ethyl ketone solvent, stir at high speed, stirring speed 1500, stirring time 15 minutes; then add 6 grams Scratch resistant auxiliary agent organic wax, 10 grams of glass powder, 1 gram of photoinitiator dichloroacetophenone, and continue to stir for 15 minutes to obtain UV curable light guide ink.

Abstract

The invention belongs to the technical field of preparation of light-guiding ink and particularly relates to scratch-resistant UV-curable light-guiding ink. The light-guiding ink comprises the following components in percentage by mass: 30%-40% of acrylic resin, 4%-8% of anti-settling agent, 4%-8% of coupling agent, 8%-15% of light-guiding nanoparticles, 3%-8% of scratch-resistant additive, 25%-40% of an organic solvent and 1%-5% of photoinitiator, wherein the sum of the percentage by mass of the components is 100%. The stable light-guiding ink prepared from the anti-settling agent, which is disclosed by the invention, can maintain the excellent dispersion and uniformity between the light-guiding nanoparticles, the agglomeration of the nanoparticles is delayed and the occurrence of the settling is prevented; and since organic montmorillonite is adopted as the anti-settling agent, the adhesion property of the ink can be improved.

Description

Technical field [0001] The invention belongs to the technical field of light guide ink preparation, and specifically relates to a scratch-resistant UV curable light guide ink. Background technique [0002] The light guide plate is an important part of the backlight module in the liquid crystal panel. When used, the light guide ink is used to print the ink into a reflective point through the screen printing technology. When the light hits each light guide point, the reflected light will diffuse to all angles , And then destroy the reflection condition and emit from the front of the light guide plate, thereby converting the point light source into a surface light source, achieving the effect of making the entire light guide plate emit uniformly. [0003] Patent application number 201110213082.4 discloses a UV curable light guide ink and a light guide plate using the ink. The light guide ink includes components: a cross-linking reaction between polyurethane acrylic resin and polyeste...
