Title:
ポリウレタンマトリックスを有する複合爆発性火薬を製造するための改良された半連続2成分法
Document Type and Number:
Japanese Patent JP5133553
Kind Code:
B2
Abstract:
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.
