PYROTECHNIC SPARK-FORCING COMPOSITION FOR THE FLYING TOYS Russian patent published in 2007 - IPC C06B33/04 C06D5/06 

FIELD: chemical industry; production of the pyrotechnic thermal complex compositions.

SUBSTANCE: the invention is pertaining to the pyrotechnic thermal compositions, in particular, to pyrotechnic compositions composed from several solid substances, at burning of which there is the gas-formation for making the thrust. The invention offers pyrotechnic spark-forcing composition for the flying toys, which contains the black powder of the fraction within the range of 100-1500 microns and the spark-forming metallic powder, which particles with the size of 5-120 microns are coated with the layer of the phenolformaldehyde resin. The invention is aimed at the increased duration of the stable smoke-forced track and its length.

EFFECT: the invention ensures the increased duration of the stable smoke-forced track and its length.
