LUMINESCENT COMPOSITION FOR HIDDEN MARKING, FIRE-PREVENTION COMPOSITION AND METHOD FOR IDENTIFICATION OF FIRE-PREVENTION COMPOSITIONS MARKING WITH APPLICATION OF COMPOSITION FOR HIDDEN MARKING Russian patent published in 2010 - IPC A62D1/00 A62C3/00 C09K11/78 C09K11/80 

FIELD: fire safety.

SUBSTANCE: luminescent composition for hidden marking, exposed when radiated with visible, infrared or ultraviolet radiation, contains binary mix, which includes luminophore with long afterglow on the basis of strontium aluminate, which is activated with europium, dysprosium and yttrium - LDP-1-3M, and photoluminophore with yellow, blue, red or white glow colour. Luminophores are taken with the mass ratio of 70:30. For even glow field, size of luminophore particles is selected in the range of 1-25 mcm, and flow glow of "Star sky" type - in the range of 20-180 mcm. Fire-prevention fireproofing composition includes fire-prevention composition and luminescent additive - specified binary mix. Method for marking of fire-prevention compositions consists in preparation of specified binary mixture, its introduction in amount of 0.01-35 wt parts per 100 wt parts of polymer binder. Produced marking is applied manually, by explication and printing methods in the form of information or graphic symbols, signs, text.

EFFECT: afterglow brightness and duration increase, as well as fire resistance, temperature range of afterglow expands, as a result, fast and reliable detection of fire-prevention composition is provided, as well as visualisation of extinguishing site.
