Malleable solid explosive and method for obtaining it

Abstract

A malleable solid explosive that is in the form of a solid block consisting, for at least 98% of its weight, of a pulverulent explosive charge and of a liquid chosen from polyol polymers of the group of polyisobutylene polyols, polybutadiene polyols, polyether polyols, polyester polyols and polysiloxane polyols, whose number-average molecular mass is between 500 and 10 000, and mixtures thereof.

         12 . A malleable solid explosive, wherein it is in the form of a block consisting, for at least 98% of its weight, of a pulverulent explosive charge and of a liquid chosen from polyol polymers of the group of polyisobutylene polyols, polybutadiene polyols, polyether polyols, polyester polyols and polysiloxane polyols, whose number-average molecular mass is between 500 and 10 000, and mixtures thereof. 
     
     
         13 . The malleable solid explosive as claimed in  claim 12 , wherein said pulverulent explosive charge represents at least 85% by weight relative to the total weight of said block. 
     
     
         14 . The malleable solid explosive as claimed in  claim 12 , wherein said explosive charge is chosen from octogen, hexogen, pentrite, CL20, TATB, ONTA, FINS, DADNE and mixtures thereof. 
     
     
         15 . The malleable solid explosive as claimed in  claim 12 , wherein said liquid is chosen from said polybutadiene polyols and mixtures thereof. 
     
     
         16 . The malleable solid explosive as claimed  claim 12 , wherein said block contains up to 2% by weight of at least one additive. 
     
     
         17 . The malleable solid explosive as claimed in  claim 16 , wherein said at least one additive is chosen from: antioxidants, anti-age-curing agents and chemical detection markers. 
     
     
         18 . The malleable solid explosive as claimed in  claim 12 , wherein said block contains:
 from 0 to 2% by weight of at least one additive, and   for at least 98% of its weight:   from 85% to 95% by weight of said explosive charge,   from 3% to 13% by weight of said liquid.   
     
     
         19 . The malleable solid explosive as claimed in  claim 12 , wherein said block or cake has a mass of between 100 g and 5 kg. 
     
     
         20 . A process for obtaining a malleable solid explosive as claimed in  claim 12 , wherein it comprises:
 the production of a paste by blending a mixture consisting, for at least 98% of its weight, of a pulverulent explosive charge and of a liquid chosen from polyol polymers of the group of polyisobutylene polyols, polybutadiene polyols, polyether polyols, polyester polyols and polysiloxane polyols, the number-average molecular mass of which is between 500 and 10 000, and mixtures thereof,   the molding of said paste in one (or more) molds and the removal from said molded paste from the mold(s) to obtain one (or more) blocks of said malleable solid explosive or the cutting of said paste to obtain blocks of said malleable solid explosive.   
     
     
         21 . The process as claimed in  claim 20 , wherein said blending is performed at room temperature or at elevated temperature, at a temperature of less than or equal to 80° C. 
     
     
         22 . The process as claimed in  claim 20 , wherein it is performed in continuous or batch mode. 
     
     
         23 . The malleable solid explosive as claimed in  claim 12 , wherein said explosive charge is chosen from octogen, hexogen, pentrite and CL20. 
     
     
         24 . The malleable solid explosive as claimed in  claim 12 , wherein said liquid consists of a hydroxytelechelic polybutadiene.
