Abstract

The invention discloses a method for manufacturing polrvinyl chloride / europium-doped strontium aluminate photoluminescent sheets, belongs to a luminous material, and in particular relates to rare earth polymer photoluminiscent material. The method comprises the following steps of: 1, preparing the following raw materials in percentage by weight: 84 to 86 percent of polrvinyl chloride resin, 4 to 8 percent of europium-doped strontium aluminate luminescent powder, and 7 to 10 percent of auxiliary material; 2, mixing; 3, extruding; and 4, rolling and stripping. The invention provides a method for manufacturing polrvinyl chloride / europium-doped strontium aluminate photoluminescent sheets which have the advantages of easy processing, lower cost and stable performance, and solves the problems of difficult processing and forming, high price and the like of inorganic materials and problems of low stability of rare-earth organic micromolecular ligands. The sheets have high after-glow brightness, the initial brightness of more than 2,000mcd / m<2>, the brightness after 10 minutes of more than 200mcd / m<2>, the brightness after 60 minutes of more than 50mcd / m<2>, and the brightness after 120 minutes of more than 20mcd / m<2>, and have long after-glow time of more than 12 hours.

Description

technical field [0001] The invention relates to a method for manufacturing a polyvinyl chloride / strontium aluminate photoluminescent sheet, which belongs to luminescent materials, in particular to rare earth polymer photoluminescent materials. Background technique [0002] Photoluminescent materials are also called super-afterglow light storage materials. It is a material with excellent properties that can emit light by itself without any power source. It has a strong ability of light absorption-light storage-luminescence. When it is irradiated by natural light and light, it absorbs and stores part of the light energy, and slowly releases it in the form of visible light in the dark. After the material actively absorbs sunlight, light, ultraviolet light, stray light and other visible light for 5-10 minutes, it can automatically emit light for more than 12 hours in the dark, and it can emit red, green, blue, yellow, purple, etc. according to actual needs. Various colored lig...
