A melt cast explosive composition consisting essentially of trinitrotoluene, a cyclic nitramine explosive selected from the group consisting of cyclotrimethylenetrinitramine and cyclotetramethylenetetranitramine, aluminum powder, and a polymer selected from the group consisting of ethylene vinyl acetate copolymer and an ethylene, vinyl acetate, vinyl alcohol terpolymer.
- 2. A composition as in claim 1 wherein said composition consists essentially of by weight about 30 percent trinitrotoluene, about 45 percent cyclic nitramine explosive, about 5 percent polymer, and about 20 percent aluminum powder.
- 3. A composition as in claim 1 wherein said polymer is ethylene vinyl acetate copolymer made from about 70 percent ethylene and about 30 percent vinyl acetate.
- 4. A composition as in claim 1 wherein said polymer is an ethylene, vinyl acetate, vinyl alcohol terpolymer, made from about 10 percent ethylene, about 85 percent vinyl acetate, and about 5 percent vinyl alcohol.
- 5. A method of making a melt cast explosive composition comprising:
- (a) to molten trinitrotoluene during agitation adding aluminum powder and particles of a cyclic nitramine explosives selected from the group consisting of cyclotrimethylenetrinitramine and cyclotetramethylenetetranitramine, said cyclic nitramine explosive particles having a coating of a polymer selected from the group consisting of ethylene vinyl acetate copolymer and an ethylene, vinyl acetate, vinyl alcohol terpolymer; and
- (b) casting the resulting composition of step (a) and allowing it to solidify to form the explosive product.
- 6. The method of claim 5 wherein said cyclic nitramine explosive particles are coated with said polymer according to the following steps:
- (a) dissolving said polymer in a solvent to form a solution;
- (b) adding said solution with stirring to a slurry of said cyclic nitramine particles in water; and
- (c) separating and drying polymer coated explosive particles.
- 7. The melt cast explosive composition of claim 1 wherein said composition is produced by:
- adding aluminum powder and particles of a cyclic nitramine explosive selected from the group consisting of cyclotrimethylenetrinitramine and cyclotetramethylenetetranitramine to molten trinitrotoluene during agitation, said cyclic nitramine explosive particles having a coating of a polymer selected from the group consisting of ethylene vinyl acetate copolymer and an ethylene, vinyl acetate, vinyl alcohol terpolymer; and
- casting the resulting composition and allowing it to solidify to form the explosive composition.
- 8. A method of making a melt cast explosive composition comprising:
- (a) to molten trinitrotoluene during agitation adding a polymer in latex form selected from the group consisting of ethylene vinyl acetate copolymer and an ethylene, vinyl acetate, vinyl alcohol terpolymer;
- (b) to the resulting mixture of step (a) while mixing, adding aluminum powder and a cyclic nitramine explosive selected from the group consisting of cyclotrimethylenetrinitramine and cyclotetramethylenetetranitramine; and
- (c) subjecting the resulting mixture of step (b) to vacuum to remove water therefrom and casting the resulting composition allowing it to solidify to form the explosive product.
- 9. The melt cast explosive composition of claim 1 wherein said composition is produced by:
- adding a polymer in latex form selected from the group consisting of ethylene vinyl acetate copolymer and and ethylene, vinyl acetate, vinyl alcohol terpolymer to molten trinitrotoluene during agitation to form a first resulting mixture;
- adding aluminum powder and a cyclic nitramine explosive selected from the group consisting of cyclotrimethylenetrinitramine and cyclotetramethylenetetranitramine to the first resulting mixture while mixing to form a second resulting mixture; and
- subjecting the second resulting mixture to vacuum to remove water therefrom, casting the resulting composition and allowing it to solidify to form the explosive composition.
- 10. The melt cast explosive composition according to claim 7 wherein said cyclic nitramine explosive particles are coated with said polymer according to the following steps:
- dissolving said polymer in a solvent to form a solution;
- adding said solution with stirring to a slurry of said cyclic nitramine particles in water; and
- separating and drying polymer coated explosive particles.
