Abstract

An energetic material comprises an energetic crystalline material substantially coated in an energetic plasticiser material.

Advantageously the energetic material comprises from 90 to 99% by weight of an energetic crystalline material and from 1 to 10% by weight of an energetic plasticiser material comprising a plasticiser selected from the group comprising Butane Triol trinitrate (BTTN), Trimethylanol ethane trinitrate (TMETN), Diazidonitrazapentane (DANPE), Glycidyl Azide Polymer (Azide Derivative) (GAP Azide), Bis(2,2-dinitropropyl)acetal /
bis(2,2-dinitropropyl)formal (BDNPA/F) or mixtures of two or more of these plasticisers.

The inventors have found that the combination of just a small quantity of energetic plasticiser material to the energetic crystalline material prior to incorporation into the bulk plasticiser, binder and filler mixture of an explosive or propellant composition has unexpected and advantageous effects.

Claims (10)

1. An energetic material comprising an energetic crystalline material substantially coated in an energetic plasticiser material.
2. An energetic material as claimed in claim 1 wherein the energetic crystalline material is particulate, the energetic plasticiser substantially coating individual particles of the energetic crystalline material.
3. An energetic material as claimed in claim 2 wherein the energetic material is in powder form.
4. An energetic material as claimed in any preceding claim wherein the energetic material comprises from 90 to 99% by weight of the energetic crystalline material and from 1 to 10% by weight of the energetic plasticiser material.
5. An energetic material as claimed in any preceding claim wherein the energetic plasticiser is selected from a group comprising Butane Triol trinitrate (BTTN), Trimethylanol ethane trinitrate (TMETN), Diazidonitrazapentane (DANPE), Glycidyl Azide Polymer (Azide Derivative) (GAP Azide), Bis(2,2-dinitropropyl)acetal / bis(2,2-dinitropropyl)formal (BDNPA/F) or mixtures thereof.
6. An energetic material as claimed in any preceding claim wherein the energetic crystalline material is hexanitrohexaazaisowurtizane.
7. A method for manufacturing an energetic material according to any preceding claim comprising;

(i) wet mixing 1 to 10% by weight of an energetic plasticiser material with 99 to 90% by weight of energetic crystalline material, and (ii) drying the wet mixed material to form a powder.
8. A method for manufacture of a propellant material containing an energetic crystalline material comprising;
(i) mixing 1 to 10% by weight of an energetic plasticiser material, with 99 to 90% by weight of the energetic crystalline material (ii) mixing and/or blending the resultant product of step (i) with additional quantities of plasticiser and binder material as appropriate for the end application of the propellant material, (iii) curing the resultant product of step (ii).
9. A method for manufacture of a propellant material as claimed in claim 8, wherein the energetic plasticiser material and energetic crystalline material are preliminarily mixed by a wet mixing process.
10. Use of an energetic material according to any one of claims 1 to 6 in the manufacture of an explosive or propellant composition.
