PYROTECHNICAL SPARK AND FORCE COMPOSITION Russian patent published in 2013 - IPC C06B33/00 

FIELD: blasting.

SUBSTANCE: pyrotechnical spark and force composition includes a thermal base, containing pyroxylin powder, potassium nitrate and metal fuel - magnesium powder, a spark agent - metal powder from the row of Al, Fe, Ti and process additives. The metal powder of the spark agent previously treated with liquid chlorinated paraffin wax CP 470 or 50% alcohol-acetone solution of fluorinated rubber SKF-26, is dispersed in the powder of red phosphorus, the weight of which makes 0.6 of potassium nitrate mass, at the following ratio of components, wt %: pyroxylin powder 27-54 potassium nitrate 9-21 manganese powder 7-11 red phosphorus 6-13 spark agent 17-30 chlorinated paraffin wax/fluorinated rubber 2-3. The feature of this composition is the fact that alternately the red phosphorus powder is used as desensitised, in the form of a coating of stannum dichloride at the mass ratio of 9:1.

EFFECT: preservation of high service properties and process parameters of a composition and creation of a colourful entertainment and sound firework effect, strongly pronounced within a distance.
