초록

Insensitive explosive compositions were prepared by reacting di-isocyanate and/or poly-isocyanate monomers with an explosive diamine monomer. Prior to a final cure, the compositions are extrudable. The di-isocyanate monomers tend to produce tough, rubbery materials while polyfunctional monomers (i.e. having more than two isocyanate groups) tend to form rigid products. The extrudable form of the composition may be used in a variety of applications including rock fracturing.

청구항

1. An insensitive explosive composition comprising an explosive oligomeric or polymeric reaction product of an explosive diamine monomer with a di-isocyanate monomer, a poly-isocyanate monomer, or mixtures thereof. 2. The insensitive explosive composition of claim 1, wherein said di-isocyanate monomer is selected from an alkyl di-isocyanate monomer or an aryl di-isocyanate monomer, and wherein said poly-isocyanate monomer is selected from an alkyl poly-isocyanate monomer or an aryl poly-isocyanate monomer. 3. The insensitive explosive composition of clai...
