Abstract

The invention discloses a method for improving the luminous intensity of light-cumulating luminous slurry. In the method, a reflecting layer and a substrate are adopted to reflect light emitted by a luminous material again so as to improve the luminous intensity. The method comprises the following operating steps: 1, printing prepared TiO2 slurry on a substrate by a 100 to 150 mesh silk screen and drying the substrate at 90 to 130 DEG C; 2, printing glass microsphere reflecting layer slurry onto the dried substrate printed with the TiO2 by using a 100 to 120 mesh silk screen, and after the printing is finished, drying the substrate at 90 to 130 DEG C; 3, finally, on the basis of the reflecting layer, printing the luminous slurry by using a 80 to 120 mesh silk screen, and after the printing is finished, drying the substrate at 110 to 150 DEG C. When the method of the invention is used, the luminous intensity and efficiency of long afterglow luminous slurry are improved greatly.

Description

Technical field: [0001] The invention belongs to the field of powder luminescent slurry, and in particular relates to a method for increasing the luminous intensity of a light storage type luminescent slurry, including the application of red, green, blue and other long afterglow slurries, and the luminous intensity can be significantly improved. Background technique: [0002] At present, green, environmentally friendly and energy-saving luminescent materials have been widely used, and alkaline earth metal aluminate luminescent materials activated by rare earth ions have become a research hotspot for long-lasting 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...
