SMOKE PYROTECHNIC COMPOSITION Russian patent published in 2016 - IPC C06D3/00 C06B29/02 C06B33/12 

FIELD: pyrotechnics.

SUBSTANCE: invention relates to means of forming smokescreens, more specifically to pyrotechnic compositions, during combustion of which is generated an aerosol, forming in air an air-dispersed formation of high optical density. Smoke pyrotechnic composition contains hexachloroethane, potassium perchlorate, aluminium powder, zinc oxide, as activating additives - mixture of powdered chlorinated paraffin and chlorinated liquid with thiourea, as process additive - pyrotechnic graphite. Introduction into mixture of powdered chlorinated paraffin and liquid chlorinated paraffin of provides formation of metal chlorides and pyrolysis soot, particles of which have size of half of incident wave of laser (1.06 mcm) and infrared (1.2 mcm) radiation, which enables to generate optically dense screen and provides considerable reduction of reflected signals due to their absorption in volume of screen, as a result, in electronic means of detection and guidance reflected signals are not identified visually with camouflage equipment, with concealed movement with operating motors.

EFFECT: composition is technologically safe and enables to make charges by extrusion moulding.
