Abstract

The invention discloses a long afterglow light-emitting fire fighting symbol which comprises a substrate and a long afterglow light-emitting material layer. The long afterglow light-emitting material layer comprises energy-storage long afterglow light-emitting materials, epoxy resin and diluent. The energy-storage long afterglow light-emitting materials are made by mixing and roasting various manganese doped oxide ultrafine particle powder. The prepared long afterglow light-emitting fire fighting symbol is low in process energy consumption, nontoxic, radioactivity-free, low in excitation condition, fast in light storage, high in afterglow brightness, long in afterglow duration, stable in light emission, and widely applicable, and the requirements for fire fighting evacuation can be well satisfied.

Description

technical field [0001] The invention relates to a fire-fighting sign and a preparation method thereof, in particular to a long-afterglow luminescent fire-fighting sign and a preparation method thereof. Background technique [0002] With the development of society and economy, the way of life of human beings is also undergoing tremendous changes, such as the concentration of human activities, the extension of night life, the continuous increase of underground buildings and high-rise buildings, and at the same time, people's awareness of potential safety hazards is also increasing . In the event of sudden disasters such as earthquakes and fires, how to ensure the safe evacuation of personnel in the shortest time, that is, how the evacuation indicator system can play its role most effectively, is a major issue that relevant technical experts from all over the world are committed to researching and solving. . [0003] At present, the fire safety and evacuation sign products us...
