Method for preparing light-cumulating luminescent size

Abstract

The invention relates to light-cumulating luminescent size and a preparation method thereof, and the preparation method has the steps as follows: 1) preparing carriers: dissolving polyester resin in a cellosolve to obtain a carrier according to the mass ratio of 1:2-4, and dissolving VMCH in a cellosolve to obtain a carrier B according to the mass ratio of 1:4-8; boosting the temperature to 70-80 DEG C in the dissolving process, and stirring while dissolving; and mixing the carrier A and the carrier B according to the ratio of 2-4:1, and preparing to obtain the required carrier; 2) mixing materials: fully mixing long afterglow luminescent materials with the carrier according to a certain ratio, adding a certain amount of dispersant, and fully stirring to balance the concentration; and 3) rolling size: fully rolling the mixed size on a three roller machine to obtain the size with the fineness of 15-100mu m. The powder particles prepared by the preparation method in the invention has more uniform agglomeration and dispersion, and can obtain fully-cumulated energy; and the luminescent size in the invention has high luminescent efficiency, can absorb energy more fully in the same period, can last longer luminescent time in a dark environment, and can be widely used.

Description

technical field [0001] The invention relates to a preparation method of a luminescent slurry, in particular to a preparation method of a light storage type luminescent slurry including red, green, blue and other long afterglow materials. Background technique [0002] At present, the application of luminescent materials has been very extensive, and the alkaline earth metal aluminate luminescent materials activated by rare earth ions have become a research hotspot of long afterglow luminescent materials. Due to the advantages of high brightness, long afterglow time, safety and reliability, etc., it is used more and more. This material emits visible light in a dark place after being irradiated by sunlight, fluorescent lamps and other light sources for a short time, and its luminous duration can reach more than ten hours at most. [0003] Due to its excellent performance, it can be widely used in various aspects, such as luminescent plastic, luminescent resin, luminescent paint...

AI Technical Summary

Problems solved by technology

[0004] However, in the application process of materials such as long afterglow, long afterglow powder is often directly mixed into the required ingredients, which is often difficult to mix well, and there is a problem of uneven dispersion of powder particles, resulting in long afterglow materials. Can not fully obtain energy storage, resulting in low luminous efficiency

In addition, as a long-lasting luminescent material, it is a powdery object, which is difficult to be widely used and brings many problems to the application.
