LOW-TEMPERATURE FLAMELESS AEROSOL-FORMING FIRE-EXTINGUISHING COMPOSITION Russian patent published in 2012 - IPC A62D1/00 

FIELD: fire-prevention facilities.

SUBSTANCE: low-temperature flameless aerosol-forming fire-extinguishing composition includes a potassium nitrate and a cellulose and fibre mass is characterised by the fact that as a flammable binder it contains starch and starch paste, and as a burning modifier - a calcium nitrate, at the following ratio of components, wt %: potassium nitrate - 30…70; calcium nitrate - 5…35; cellulose-fibre mass -5…35, starch paste - 5…25, starch - 5…25. The technical result is development of a composition, in which a flammable binder has low combustion heat and relatively high content of oxygen in a molecular link, which makes it possible to change composition burning into a low-temperature flameless mode with preservation of acceptable parameters of fire-extinguishing efficiency and content of carbon monoxide.

EFFECT: expansion of methods for further treatment of an aerosol-forming composition mass due to application of a starch paste.
