Abstract

The invention provides an improved production method of nanometer light guide particles. The method solves the technical problems that the steps of the existing preparation method are too complicated;the manual operation is needed; the preparation efficiency is low, and the like. The improved production method of the nanometer light guide particles comprises the following steps of a, under the ultrasonic agitation effect, 10 percent of absolute ethyl alcohol, 5 percent of terpilenol, 6 percent of stearic acid, 8 percent of coupling agents, 4 percent of fluorescent powder and 58 percent of nanometer light guide powder are weighed through being metered in percentage by mass to subject to surface treatment for 16min; b, 9 percent of scratch-resistant auxiliary agents are continuously added into the nanometer light guide powder treated in the step a and keep stirring, so that the nanometer light guide powder and the scratch-resistant auxiliary agents are uniformly mixed; c, the mixture issubjected to spray drying; crushing is performed through an air flow crushing system; the nanometer light guide particles are prepared. The improved production method has the advantage of high production efficiency.

Description

technical field [0001] The invention relates to a production method, in particular to an improved production method of nano light-guiding particles. Background technique [0002] The light guide plate is made of optical-grade acrylic sheet, and then high-tech materials with high reflectivity and non-absorbing light are used to print light-guiding points on the bottom surface of the optical-grade acrylic sheet with UV screen printing technology. The optical-grade acrylic plate is used to absorb the light emitted from the lamp to stay on the surface of the optical-grade acrylic plate. When the light hits each light guide point, the reflected light will spread to all angles, and then destroy the reflection condition and be emitted from the front of the light guide plate. Through light guide points of various densities and sizes, the light guide plate can be made to emit light evenly. [0003] After searching, for example, Chinese patent literature discloses a method for prepar...
