METHOD OF OBTAINING OF PYROTECHNICAL IGNITER COMPOSITION Russian patent published in 2015 - IPC C06B33/02 C06B27/00 

FIELD: demolition works.

SUBSTANCE: method of obtaining of pyrotechnical igniter composition comprises the mixing of polytetrafluoroethylene (PTFE) and metal powder in the ratio, wt %: polytetrafluoroethylene (PTFE) 5-15, metal powder 95-85. The metal powder is a powder of aluminium magnesium alloy with the aluminium contents 48 wt % and magnesium 52 wt %. An obtained mix is subject to machining with shock and abrasive action with a doze of mechanical energy 10-50 J/g. The mechanically machined mix is mixed with polytetrafluoroethylene (PTFE) in the ratio, wt %: 89.4-82.1:10.6-17.9 respectively.

EFFECT: method allows to increase combustion heat and combustion temperature, and also to increase the content of the condensed combustion products.
