| titleOfInvention | Semi-continuous dual-component method for obtaining a polyurethane-matrix composite explosive charge |
| abstract | The subject of the present invention is a semi-continuous process for obtaining a composite explosive charge consisting of a solid polyurethane matrix charged whose charge is pulverulent and includes at least one nitrated explosive organic. Said method comprises the following successive stages: obtaining a pasty explosive composition essentially consisting of ingredients hereinafter: ~ a polyol prepolymer, ~ a polyisocyanate monomer, ~ a plasticizer, and ~ a pulverulent solid charge comprising at least one nitro-organic explosive, by continuous mixing of a pasty component and of a liquid component B ', prepared, discontinuously, from said constituent ingredients; - the introduction into a mold of said pasty explosive composition; and - the thermal crosslinking of said composition in said mold; and is characterized in that: - said component B 'liquid comprises 90 to 99% by weight of said polyisocyanate monomer; - said A pasty component comprises the entire polyol prepolymer, the entire the powdery solid filler and the remaining 1 to 10% by weight of the monomer polyisocyanate; the plasticizer being indifferently distributed between said components A 'and B'; and in that the continuous mixing of said components A ' and B 'is implemented so that the component mass ratio A '/ component B' is constant, between 95.05 / 4.95 and 99.55 / 0.45. said process constitutes a particularly interesting improvement in the process according to EP-AI 133 015. |
