초록

The invention permits the continuous industrial manufacture in series of small crosslinked composite pyrotechnic charges without any "pot life" constraint since the binder does not change at ambient temperature.

청구항

[ We claim:] [1.] Continuous process for solvent-free manufacture of finished composite pyrotechnic products in which the starting constituents include especially a liquid binder which is crosslinkable at a temperature higher than 40.degree. C. and at least one solid oxidizing energetic filler, the process consisting especially:i) in mixing the starting constituents of the said products so as to obtain a homogeneous composite dough of sufficient viscosity to be capable of retaining stable geometrical dimensions.ii) in giving the dough thus obtained the f...
