Description
Technical field
The invention belongs to light guide ink preparing technical field, and in particular to a kind of preparation method of photocuring light guide ink.
Background technology
Light guide plate is important component in backlight module in liquid crystal panel, is printed when using using light guide ink by half tone
Brush technology, reflective spot is printed as by ink, when light is irradiated to each light guiding points, and reflected light can spread toward all angles, so
Destruction conditioned reflex is projected by light guide plate front afterwards, so that spot light is changed into area source, is reached so that whole light guide plate is sent out
The uniform effect of light.
Number of patent application 201110213082.4 discloses a kind of UV solidification light guide inks and the light guide plate using the ink.
The light guide ink includes component：Polyurethane acrylic resin and polyester acrylate crosslink reaction, and guide-lighting powder distribution and
The polymer of graft reaction generation, and diluent, light trigger occur for polyurethane acrylic resin, polyester acrylate.Poly- ammonia
Ester acrylic resin makes light guide ink have adhesive force well, guide-lighting powder is not assembled or is come off, so as to play very well
The effect of ground scattered light.But the patent does not provide whether the light guide ink after solidification has scratch resistance.ASTM D 5178-
98 point out, scratch resistance refers to the ability of coating resistance damage caused by slight friction.
The content of the invention
For problems of the prior art, it is an object of the invention to provide a kind of preparation of photocuring light guide ink
Method.
The technical scheme for realizing the object of the invention is：A kind of preparation method of photocuring light guide ink, its preparation process is：
1）Under the conditions of lucifuge, it is calculated in mass percent, takes 25%~45% acrylic resin, 3%~10% stearic acid is molten
Enter 30%~45% toluene and the in the mixed solvent of butanone, high-speed stirred, the rpm of mixing speed 1500~2000, mixing time 10
~20 minutes；
2）The guide-lighting powder of 2%~6% damage resistant auxiliary agent, 8%~18% nanometer, 1%~5% light trigger are continuously added, continues to stir
Mix 10~20 minutes, that is, UV solidification light guide inks are made.
Preferably, the guide-lighting powder of described nanometer is high refractive index transparent oxide, including titanium oxide, zinc oxide, aluminum oxide
In one or more.
Preferably, described damage resistant auxiliary agent includes the one or more in beeswax, organic wax, ptfe micropowder.
Preferably, described damage resistant auxiliary agent is preferably ptfe micropowder.
Preferably, described light trigger is radical photoinitiator.
It is further preferred that described optical free radical type light trigger is Dialkoxy acetophenones.
The advantage of the invention is that：
1. toluene and butanone mixed solvent that the present invention is selected, the light guide ink of its stabilization being configured to, can keep nanometer
Good dispersiveness and uniformity, delay the reunion between particle between guide-lighting particle.
2. the present invention is used as dressing agent, surface shape of the stearic acid in the guide-lighting particle of nanometer from stearic acid or stearate
Into spatial obstacle layer, the aggregation of guide-lighting nano-particle can be effectively prevented.
3. there is light guide ink prepared by the present invention good screen printability, acrylic resin to have after solidifying through UV
Good pliability, it is good to acrylic board adhesive force, keeping flexible while can improve by adding damage resistant auxiliary agent
The hardness of ink film, its pencil hardness can reach 2H.
4. the preparation method technique of the present invention is simple, obtained light guide ink performance is good.
