초록

An extrudable ammunition priming mix with viscosity characteristics which remain relatively stable over an extended time span. The stabilized viscosity is obtained by incorporating an effective amount of guar gum into the priming mix. The primer thus displays improved pot life so that larger batches may be made and used over an extended period of time.

청구항

A water-bearing extrudable explosive primer mix having improved rheological stability comprising: (a) about from 25 to 60% lead styphnate, (b) about from 1 to 10% tetracene, (c) about from 0 to 10% pentaerythritol tetranitrate (PETN), (d) about from 20 to 60% barium nitrate, (e) about from 0 to 25% antimony sulfide, (f) about from 0 to 10% aluminum, (g) an amount of water effective to reduce said mix to an extrudable consistancy, and (h) an amount of guar gum effective to substantially stabilize the consistancy of said extrudable mix.
