A composite explosive with a rubbery binder comprises particles of explosive material dispersed into a rubbery binder. The binder is a carboxylic polydiolefin based resin, the proportion of explosive material amounting to not more than 92 percent by weight of the composite explosive. To prepare the composite explosive, at least one carboxylic polydiolefin and at least one chain extending agent and/or reticulating agent are mixed with the particles of explosive substance. Said agent contains in each molecule at least two functional groups capable of reacting with the -COOH groups in the carboxylic polydiolefin. The resultant material is then poured. The reaction of the carboxylic polydiolefin and the said agent entrains the resin constituting the binder. The composite explosive according to the invention is used in applications requiring the use of homogeneous explosives of easy operation. |
