Abstract
The present invention relates to modified propellant compositions of either single or multiple based type which are obtained by resolvating a conventional, previously solvated nitrocellulose-based granular propellant with a solvent such as methyl ethyl ketone followed by the addition of glycerine to replasticize the composition and create a slurry. Upon evaporation of the solvent, a waterproof and self-supporting explosive composition is produced which is extremely stable and resistant to impact, friction and static discharge.
Claims38
A method for producing a waterproof and caseless nitrocellulose-based propellant comprising:
- a) providing a dried high nitrogen content previously solvated nitrocellulose based propellant;
- b) resolvating the solvated nitrocellulose-based propellant with a solvent to form a slurry;
- c) adding glycerine to the resolvated nitrocellulose based propellant slurry;
- and,
- d) recovering the solvent from the slurry to dry the same and thus produce the waterproof and caseless nitrocellulose-based propellant.
A method for producing a waterproof and caseless nitrocellulose-based propellant comprising:
- a) providing a high nitrogen content dehydrated nitrocellulose guncotton;
- b) solvating the nitrocellulose guncotton in a solvent to form a first slurry;
- c) adding selected energetic bases to the first slurry;
- d) casting and curing the first slurry into sheets;
- e) pulverizing the cured sheets into a dried powder;
- f) resolvating the dried powder to form a second slurry;
- g) adding glycerine to the second slurry;
- and,
- h) recovering the solvent from the second slurry to dry the same and thus produce the waterproof and caseless nitrocellulose-based propellant.
