Abstract

Provided is a melt-castable binder useful for stabilizing high energy explosive materials. A melt-castable nitramine binder has high energy in its own right yet is very insensitive to accidental detonation such as by shock or friction. The melt-castable nitramine binder is optionally combined with one or more high energy materials in the formation of an explosive composition with improved energy yield and safety and handling parameters relative to the high energy material alone.

First claim

We claim:

1. A detonable composition comprising:
A detonable energetic material with a detonation velocity of 5.5 km/s or greater as measured by laser induced shock;
a melt-castable nitramine binder with a melting point of 150 degrees Celsius or below; and
wherein said melt-castable nitramine binder comprises a structure of Formula I

where n=1, 2, or 3 and n*=1, 2, or 3.

2. The composition of claim 1 wherein n and n* are each 1.

3. The composition of claim 1 wherein said melt-castable nitramine binder has a melting point of 80 degrees Celsius to 90 degrees Celsius.

4. The composition of claim 1 wherein said detonable energetic material is: 1,3,5,7-tetranitro-1,3,5,7-tetrazocane (1,3,5,7-tetranitro-1,3,5,7-tetrazocane; HMX); 2,2-bis(hydroxymethyl)1,3-propanediol (pentaerythritol tetranitrate; PETN); 2,4,6-trinitrotoluene (2-methyl-1,3,5-trinitrobenzene; TNT), 1,2,3-trinitroxypropane (trinitroglycerin; TNG); 2,3-dimethyl-2,3,-dinitrobutane (2,3-dimethyl-2,3-dinitrobutane; DMDNB); triacetone triperoxide (TATP); hexamethylene triperoxide diamine (HMTD); other peroxide or nitrate based explosive materials; gunpowder(s); pentaerythritol (2,2-Bis(hydroxymethyl)1,3-propanediol; PE); military or commercial grades of C4; Semtex A1; Semtex H; 2,4-dinitroanisole (DNAN), 1,3-Dinitrobenzene (1,3-DNB); 1,3,5-Trinitrobenzene (1,3,5-TNB); hexanitrostilbene (HNS); croconic acid; pentolite; 2,4,6-triamino-1,3,5-trinitrobenzene (TATB); comp B; nitrotriazalone (NTO); hexanitrohexaazaisowurtzitane (CL-20); 1,1-diamino-2,2-dinitroethene (DADNE; FOX-7); or combinations thereof.

5. An explosive composition comprising:
a detonable energetic material with a detonation velocity of 5.5 km/s or greater as measured by laser induced shock; and
a melt-castable nitramine binder comprising a structure of Formula I

where n=1, 2, or 3 and n*=Q 1, 2, or 3.

6. The composition of claim 5 wherein n and n* are each 1.

7. The composition of claim 5 wherein said detonable energetic material is: 1,3,5,7-tetranitro-1,3,5,7-tetrazocane (1,3,5,7-tetranitro-1,3,5,7-tetrazocane; HMX); 2,2-bis(hydroxymethyl)1,3-propanediol (pentaerythritol tetranitrate; PETN); 2,4,6-trinitrotoluene (2-methyl-1,3,5-trinitrobenzene; TNT), 1,2,3-trinitroxypropane (trinitroglycerin; TNG); 2,3-dimethyl-2,3,-dinitrobutane (2,3-dimethyl-2,3-dinitrobutane; DMDNB); triacetone triperoxide (TATP); hexamethylene triperoxide diamine (HMTD); other peroxide or nitrate based explosive materials; gunpowder(s); pentaerythritol (2,2-Bis(hydroxymethyl)1,3-propanediol; PE); military or commercial grades of C4; Semtex A1; Semtex H; 2,4-dinitroanisole (DNAN), 1,3-Dinitrobenzene (1,3-DNB); 1,3,5-Trinitrobenzene (1,3,5-TNB); hexanitrostilbene (HNS); croconic acid; pentolite; 2,4,6-triamino-1,3,5-trinitrobenzene (TATB); comp B; nitrotriazalone (NTO); hexanitrohexaazaisowurtzitane (CL-20); 1,1-diamino-2,2-dinitroethene (DADNE; FOX-7); or combinations thereof.
