ABSTRACT:
In the military field of explosive munitions, a semi-continuous process produces a composite explosive charge composing a charged solid polyurethane matrix, the charge of which is pulverulent and comprise at least one nitro-organic explosive, by introduction into a mould of a pastry explosive composition and then thermal crosslinking of this composition. The composition is obtained by mixing constituents essentially comprising a polyol prepolymer, a plasticizer, a polyisocyanate monomer and a pulverulent solid charge comprising at least one nitro-organic explosive. This simple and economic process makes it possible to dispense, without disadvantage, with the pot life/curing time of the composition compromise.
