RETARDING COMPOSITION (VERSIONS) Russian patent published in 2008 - IPC C06B33/00 C06B33/12 

FIELD: chemistry.

SUBSTANCE: invention relates to pyrotechnics. Two variants of the pyrotechnics retarding composition are suggested. According to variant 1 the composition contains wolfram powder as fuel, oxide lead PbO₂ or Pb₃O₄ or the mixture with barium chromate as an oxygen carrier and fluoroplastics as a binding agent in quantity from 0.2 to 2 w.% over the weight of the oxygen agent and fuel. According to variant 2 the composition contains powder mixture of wolfram and silicon as fuel, oxide lead PbO₂ or Pb₃O₄ or their mixture as an oxygen carrier and fluoroplastics as a binding agent in quantity from 0.2 to 2 w.% over the weight of oxygen agent and fuel. The invention is aimed at dependence decrease of the compound burning speed and their stability during long-term storage in humid conditions.

EFFECT: dependence decrease of burning speed of the pyrotechnics compounds.
