Abstract

The invention discloses a quick-drying durable luminescent material, which comprises the following raw materials in parts by weight: 50-70 parts of deionized water, 12-16 parts of ethyl acrylate, 8-12 parts of methyl cellulose, 3-6 parts of persulfuric acid, 1-4 parts of aluminum sulfate, 2-5 parts of vinyltrimethoxysilane, 6-10 parts of propylene carbonate, 55-60 parts of Sr2O3, 25-30 parts of Al2O3, 7-9 parts of Y203, 5-7 parts of Yb203, and 1-3 parts of Tm203. According to the luminescent material obtained by the method provided by the invention, under the same condition, the afterglow time is relatively long and can reach 600 minutes or above, and meanwhile, the drying time of the material is greatly reduced and can be shortened by 15 seconds or above, so that a very good quick-drying effect is achieved.

Description

technical field [0001] The invention relates to the field of materials, in particular to a quick-drying and durable luminescent material and a preparation method thereof. Background technique [0002] Substances that can emit light after being excited by the outside world are called luminescent materials, and luminescent materials are one of functional materials. People are no strangers to luminous substances, and they can be seen almost everywhere in the home or in public places. Luminescent substances are at the core of airport x-ray security inspection machines and computer monitors. Of course, they are not only used in expensive equipment, but also in banknotes that are commonly used. Luminescent substances have already become an indispensable material in people's daily life, and they are widely used in many aspects such as large-screen color display panels, lighting equipment, computer monitors, and fluorescence detection and immunoassay. Luminescent materials can be ...
