Abstract (en)
[origin: EP1333015A2] Semi-continuous production of a composite explosive charge (I) consisting of a solid polyurethane matrix filled with powder (II) containing nitrated organic explosive(s), by charging a mold with a paste obtained by mixing a polyol prepolymer (III), plasticizer (IV), polyisocyanate monomer (V) and (II) then thermally crosslinking. Semi-continuous production of a composite explosive charge (I) consisting of a solid polyurethane matrix filled with powder (II) containing nitrated organic explosive(s), by charging a mold with a paste obtained by mixing a polyol prepolymer (III), plasticizer (IV), polyisocyanate monomer (V) and (II) then thermally crosslinking, includes: (i) discontinuously forming the following homogeneous mixtures by simple mixing: (a) a paste comprising the whole of (II) and (III); and (b) a liquid comprising the whole of (V) ((IV) being distributed between (a) and/or (b) as required); and (ii) continuously mixing (a) and (b) at a weight ratio of 95-99.5 : 5-0.5.
