| titleOfInvention | Semi-continuous two-component methods for obtaining a composite explosive charge of polyurethane matrix |
| abstract | METHOD OF TWO SEMI-CONTINUOUS COMPONENTS FOR OBTAINING A COMPOSITE EXPLOSIVE POLYURETHANE MATRIX LOAD The invention relates to a semi-continuous two-component method for obtaining a composite explosive charge consisting of a solid charged polyurethane matrix, which is charge in the form of a powder and comprising at least one organic nitro explosive. Said method includes the following successive steps: obtaining a pasty explosive composition consisting essentially of the following constituent ingredients: a polio prepolymer, a polysocyanate monomer, a plasticizer and a solid powdered form comprising at least an organic nitro explosive, continuously mixing a pasty component A 'and a liquid component B' prepared individually from said constituent ingredients; introducing said composite explosive composition into a mold; and thermally crosslinking said composition in said mold. The invention is characterized in that said liquid component B 'comprises from 90 to 99% by weight of said polyisocyanate monomer; said component A 'comprises the entire polyol polymer, the total powdered solid filler and the remainder 1 to 10% by weight of the polyisocyanate monomer; the plasticizer being distributed indistinctly between components A 'and B'; wherein the continuous mixing of said components A 'and B' is such that the mass ratio of component A '/ component B' is constant, ranging from 95.05 / 4.95 to 99.5 / 0.45. Said method constitutes a particularly interesting improvement of the method according to EP-A-1 133015. |
