COMPOSITION FOR HIGH ENERGY PYROTECHNICAL IGNITION ELEMENT Russian patent published in 2017 - IPC C06B45/00 C06C9/00 C06B27/00 C06B33/00 

FIELD: blasting.

SUBSTANCE: composition of a high-energy pyrotechnic incendiary element in cumulative fragmentation warfare articles containing a fluoropolymer and aluminium powders characterized in that the composition contains 70-90% of the mass of the copolymer of tetrafluoroethylene and vinylidene fluoride, or a copolymer of tetrafluoroethylene and perfluoro-propyl ether, or a mixture consisting of 50% Polytetrafluoroethylene and 50% by weight. Vinylidene fluoride or polyvinylidene fluoride, and 10-30% by weight. Nanodispersed aluminium powder with a specific surface area of 5-16 m²/g, or a mixture of aluminium poly-borides with a specific surface area of 10-30 m²/g, or a mechanical mixture of aluminium poly-borides with nano-aluminium, in which the nano-aluminium contains 10 to 50% by weight, Complete warming up of the powder mixture to introduce particles of active metal powders into the softened fluoropolymer and ensure contact between the components, and then pressing the resulting pyrotechnic ignition element at a temperature of 150-220°C and a pressure of 85 kgf/cm².

EFFECT: composition of a high-energy pyrotechnic incendiary element is obtained, which has a high calorific value, a small delay in ignition and autoignition.
