METHOD OF OBTAINING ELASTIC EXPLOSIVE COMPOSITION Russian patent published in 2011 - IPC C06B21/00 C06B25/34 

FIELD: technological processes.

SUBSTANCE: invention relates to methods of obtaining elastic explosive compositions, which can be sued in production of charges of different geometrical shape of various purposes (detonating cables, layouts, etc.) by methods used for processing of thermoplastic materials. Method of obtaining explosive composition includes preliminary flegmatisation of explosive substance with mixture of solvents of thermoplastic elastomers with plastisiser and technological additives, after which into mixture additionally introduced is (5÷15)% solution of first thermoplastic elastomer in its solvent and said plastisised thermoplastic elastomer and then (5÷15)% solution of second thermoplastic elastomer in its solvent and said plastisises thermoplastic elastomer with further mixing for 45÷90 min at temperature 50÷90°C with further vacuuming.

EFFECT: method makes it possible to obtain elastic explosive composition with high degree of homogeneity, which ensures detonation rate not lower than 7500 m/s with charge density 1.6 g/cm³.
