AEROSOL-FORMING AND FLAME-ARRESTING COMPOSITION Russian patent published in 2008 - IPC A62D1/06 

FIELD: fire-fighting component.

SUBSTANCE: can be used for volumetric extinguishing of Class A, B and C fires in enclosed or semi-closed spaces. Aerosol-forming and flame-arresting composition contains oxidizer - potassium perchlorate and potassium nitrate in weight fraction from 1 to 1.3, from 1 to 1.4, oxygenic binding agent - epoxy resin, combustion modifier and processing aid. Metallic oxide with several common oxidation states in the amount 35-45 mae. %, carbons black in the amount 17-25 mae. % and phenol-formaldehyde resin on the amount 35-45 mae. % are used as combustion modifier. Weight fraction of combustion modifier is 2.1% to 3%. Either polyethylenepolyamine or triethylenetetramine and maleic anhydride is included into composition as processing aid.

EFFECT: increase of compound burning time velocity at atmospheric conditions of combustion; decrease of specific consumption; improvement of physical and mechanical characteristics.
