Abstract

The invention discloses nano photoconductive particles for photoconductive ink and belongs to the technical field of photoconductive ink preparation. The photoconductive particles contain the ingredients in percentage by mass: 5-10% of stearic acid, 5-10% of coupling agent, 60-80% of nano photoconductive powder and 5-15% of scratch resisting auxiliaries. The photoconductive particles have the advantages that the photoconductive particles have a light extinction effect, have unique slippery hand feel, particularly cannot absorb UV (Ultraviolet) and do not affect the energy absorption of a photoinitiator, and meanwhile, transparent and excellent texture and scratch and wear resisting effects are maintained; the photoconductive particles disclosed by the invention have good heat resistance and dispersity, are applicable to optical application products and can provide an excellent optical diffusion effect and good brightness performance.

Description

technical field [0001] The invention belongs to the technical field of light-guiding ink preparation, and in particular relates to nano light-guiding particles for light-guiding ink. Background technique [0002] The light guide plate is an important part of the backlight module in the liquid crystal panel. When using the light guide ink, the ink is printed into reflective points through screen printing technology, so that the point light source is converted into a surface light source, so that the entire light guide plate can emit light uniformly. Effect. The composition of the light guide ink will directly affect the quality of the light guide point, and the quality of the light guide point will directly affect the brightness uniformity of the light guide plate. [0003] The main problems of the currently used light-guiding inks are that the resulting light-guiding plates have low luminance and poor luminous uniformity, and at the same time, the solvents contained in the ...
