    • 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.
    • 本发明涉及用于获得复合炸药的半连续双组分方法,所述复合炸药由填充物为粉末基且填充有至少一种有机硝化炸药的填充固体聚氨酯基质组成。 所述方法包括以下连续步骤:获得主要由以下成分组成的糊状炸药组合物:多元醇预聚物,多异氰酸酯单体,增塑剂和包含至少一种有机硝化炸药的基于粉末的固体填料, 过去的组分A'和一种液体组分B',由所述组分成分分散制备; 将所述膏状炸药组合物引入模具中; 并在所述模具中热交联所述组合物。 本发明的特征在于所述液体组分B'包含90至99wt。 所述多异氰酸酯单体的% 所述糊状组分A'包含全部多元醇聚合物,全部粉末基固体填料和剩余的1至10wt。 %的多异氰酸酯单体; 增塑剂无差别地分布在所述组分A'和B'之间; 并且其中进行所述组分A'和B'的连续混合物,使得组分A'/组分B'质量比恒定,范围在95.05 / 4.95和99.5 / 0.45之间。 所述方法对根据专利EP-A-I 133015的方法构成了特别有意义的改进。
