Improved production method of nano light guide particles

Abstract

The invention provides a production method of improved nano light guide particles, which solves the technical problems that the existing preparation method includes complicated procedures, requires the manual operation and results in low preparation efficiency, and the like. The improved production method of the nano light guide particles comprises the following steps: a, weighing 6 to 12 percentof absolute ethyl alcohol, 3 to 8 percent of terpilenol, 4 to 7 percent of stearic acid, 6 to 12 percent of coupling agent, 3 to 5 percent of fluorescent powder and 50 to 76 percent of nano light guide powder by mass under an ultrasonic stirring effect, and performing the surface treatment for 10 to 24 min; b, continuously adding 3 to 11 percent of scratch-resistant additive into the nano light guide powder processed in step a, continuously stirring, and uniformly mixing the nano light guide powder and the scratch-resistant additive; and c, spray drying the mixture, and crushing by virtue of an air flow crushing system, thus obtaining the nano light guide particles. The improved production method of the nano light guide particles has the advantage of high production efficiency.

Description

technical field [0001] The invention relates 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 preparing diffusion particles used in light-...

Problems solved by technology

[0004] Although the preparation method disclosed in this patent can provide excellent optical diffusion effect and good brightness performance, the steps of the preparation method are too complicated, manual operation is required, and the preparation efficiency is low. Therefore, an improved nano-light guide Particle production methods are necessary
