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.

[ 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 form of intermediate products which have the geometrical dimensions of the said finished products,iii) in setting the form and the composition of the intermediate products thus obtained by crosslinking the binder, racterized in that:iv) the said starting liquid binder is first of all mixed with a solid thickening filler in pulverulent form so as to obtain a premix of greasy consistency which is subsequently mixed with the said energetic fillers,v) the mixing and forming operations are conducted at a temperature lower than 40.degree. C.
