Abstract (en)

[origin: EP1790626A1] Semi continuous process of forming a composite explosive charge having a charged solid polyurethane matrix comprises: forming a pastry explosive composition (containing a polyol prepolymer, a polyisocyanate monomer, a plasticizer and a pulverulent solid charge having at least one nitro-organic explosive) by continously mixing a liquid component A having the monomer and a pastry component B1 having the prepolymer and the filler in which the plasticizer is distributed between the components; and introducing and thermal crosslinking the composition in to a mould. Semi continuous process of forming a composite explosive charge having a charged solid polyurethane matrix comprises obtaining a pastry explosive composition (containing a polyol prepolymer, a polyisocyanate monomer, a plasticizer and a pulverulent solid charge having at least one nitro-organic explosive) by continously mixing a liquid component A having the monomer at 90-99 wt.% and a pastry component B1 having the prepolymer and the filler together at 1-10 wt.% in which the plasticizer is distributed between the components; introducing the composition in to a mould; and thermal crosslinking the composition in the mould, where the A:B1 weight ratio is 95.05:4.95-99.55:0.45.
