EXPLOSIVE COMPOSITE WITH SLOW DETONATION SPEED AND PLANE OR LINEAR WAVE GENERATOR INCLUDING

摘要

The present invention relates to a composite explosive containing organic energy charges and inert particulate fillers in a binder. Typically: said binder is a polyurethane, obtained by crosslinking, via its terminal hydroxy functions, of a hydroxytelechelic polybutadiene, with at least one crosslinking agent of polyisocyanate type; said hydroxytelechelic polybutadiene having a number average molecular weight (Mn) of between 1800 and 3500 gmol-1, preferably between 2400 and 3500 gmol-1; and - said inert particulate fillers, whose median diameter (d50) is less than or equal to 300 μm (d50 ≤ 300 μm), consist of dense inert particulate fillers, of a lead-free material, having a density greater than 8 , advantageously greater than 10; said composite explosive having a detonation rate in diameter 25 mm less than 5000 m / s, preferably between 3000 and 5000 m / s.
