| titleOfInvention | Semi-continuous dual-component method for obtaining a polyurethane-matrix composite explosive charge |
| abstract | The invention concerns a semi-continuous dual-component method for obtaining a composite explosive charge consisting of a filled solid polyurethane matrix whereof the filler is powder-based and comprising at least one organic nitrated explosive. Said method includes the following successive steps: obtaining a pasty explosive composition essentially consisting of the following ingredients: a polyol prepolymer, a polyisocyanate monomer, a plasticizer, and a powder-based solid filler comprising at least one organic nitrated explosive, by mixing continuously a past component A' and a liquid component B', prepared, discretely, from said constituent ingredients; introducing into a mold said pasty explosive composition; and thermally crosslinking said composition in said mold. The invention is characterized in that said liquid component B' comprises 90 to 99 wt. % of said polyisocyanate monomer; said pasty component A' comprises the total polyol polymer, the total powder-based solid filler and the remaining 1 to 10 wt. % of the polyisocyanate monomer; the plasticizer being indifferently distributed between said components A' and B'; and in that the continuous mixture of said components A' and B' is performed such that the component A'/component B' mass ratio is constant, ranging between 95.05/4.95 and 99.5/0.45. Said method constitutes a particularly interesting improvement to the method according to patent EP-A-I 133015. |
