RETARDING PYROTECHNIC COMPOUND (VERSIONS) Russian patent published in 2007 - IPC C06B33/00 C06B33/12 

FIELD: chemical industry; production of the retarding pyrotechnic compounds.

SUBSTANCE: the invention is pertaining to the field of pyrotechnics. The invention offers two versions of the retarding pyrotechnic compound. The first version provides, that the compound contains the wolfram powder as the fuel, PbO₂ or Pb₃O₄, or their mixture either their mixture with barium chromate as the oxidant and as the binding - the copolymer of polytrifluorochloroethylene with vinylidene fluoride C₄H₂ClF₅ in amount from 0.2 up to 2 mass % above the mass of the oxidant and the fuel. In the second version the compound contains the mixture of the powders of wolfram and silicon - as the fuel, PbO₂ or Pb₃O₄, or their mixture - as an oxidant and the binding - the copolymer of polytrifluorochloroethylene with vinylidene fluoride_{C4H2C1F5 in amount from 0.2 up to 2 mass % above the mass of the oxidant and the fuel. The invention is intended to ensure the increased stability of the characteristics of the retarding pyrotechnic compound and to heighten stability of its characteristics at the prolonged storage as well as in the humid conditions.}

EFFECT: the invention ensures the increased stability of the characteristics of the retarding pyrotechnic compound the heighten stability of its characteristics at the prolonged storage as well as in the humid conditions.
