Abstract

The invention discloses a polrvinyl chloride / strontium europium aluminate photoluminescence sheet, belongs to luminous materials, and in particular relates to a rare-earth macromolecule photoluminescence materials. The polrvinyl chloride / strontium europium aluminate photoluminescence sheet comprises the following components in percentage by weight: 84 to 86 of polrvinyl chloride resin, 4 to 8 of strontium europium aluminate luminous powder and 7 to 10 of auxiliary material. The invention provides the polrvinyl chloride / strontium europium aluminate photoluminescence sheet which has the advantages of easy processing, lower cost and stable performance and a processing method thereof, which solve the problem of difficult processing shaping, high price and the like of inorganic materials and low stability of rare-earth organic micromolecule coordination compounds. The sheet has high afterglow luminance, the initial luminance is more than 2,000mcd / m<2>, and the initial luminance is more than 200mcd / m<2> for 10 minutes, more than 50mcd / m<2> for 60 minutes and 20mcd / m<2> for 120 minutes, and the afterglow time is long, which is over 12 hours. The polrvinyl chloride / strontium europium aluminate photoluminescence sheet is applied to concealed lighting and emergency lighting, and meter panels of passenger vehicles and freight vehicles for aviation, voyage and land, building decoration and plates of roads, docks, common facilities, paths and dangerous label marks.

Description

technical field [0001] The invention relates to a polyvinyl chloride / strontium aluminate europium 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 lights. The process ...
