Embodiment 1

[0039] A pyrotechnic composition according to the invention was prepared with the following composition: 94.8 wt% nitrocellulose (13.5% N); 5 wt% strontium-aminotetrazole complex; and 0.2 wt% ammonium chloride.

[0040] The pyrotechnic composition was prepared by mixing 100 grams of dry NC 13.5% with 5.27 grams of strontium-aminotetrazole complex and 0.22 grams of ammonium chloride. Acetone was then added to the mixture, and the mixture thus obtained was mixed until the composition could be formed into strands with a diameter of 10 mm in a ram extrusion process. Acetone was removed at room temperature. The strands thus obtained were cut into 10 mm long pellets, which were further processed in the fireworks production. Firework products have a red flame when burned.

Embodiment 2

[0042] A pyrotechnic composition according to the invention was prepared with the following composition: 83 wt% ammonium nitrate; 6 wt% barium-aminotetrazole complex with hydrogen chloride; and 11 wt% nitrocellulose (13.5% N2). The pyrotechnic composition is dry mixed in a turbulator. After mixing, the composition was compressed into granules with a diameter of 15 mm. The composition thus prepared burns with a green flame.

Embodiment 3

[0044] A pyrotechnic composition according to the invention was prepared with the following composition: 48 wt% ammonium perchlorate; 17 wt% aminotetrazole; 5 wt% strontium-aminotetrazole complex; and 30 wt% nitrocellulose (13.5% N2). The pyrotechnic composition is dry mixed in a turbulator. After mixing, the composition was compressed into granules with a diameter of 15 mm. The composition thus prepared burned with a red flame.

Abstract

The invention provides a chlorine-containing pyrotechnic composition which comprises a binder, an oxidator, a pyrotechnic fuel, and a colourant comprising a metal salt of 5-aminotetrazole. The invention further relates to a firework article comprising such a pyrotechnic composition. In addition, the invention provides a method for preparing said colourant.

Description

technical field [0001] The present invention relates to a pyrotechnic composition containing 5-aminotetrazolium salt, preferably a pyrotechnic composition (fireworks composition) containing 5-aminotetrazolium salt. Background technique [0002] Traditional colored fireworks have the major disadvantage that they produce a large amount of smoke which causes serious problems in closed assembly places such as inner city stadiums. [0003] In US 6,214,139 and US 5,917,146 various metal salts of high nitrogen, low carbon content energetic materials are proposed as viable ingredients for low smoke fireworks compositions. [0004] However, the high nitrogen, low carbon content energetic materials mentioned in these documents are not readily available compounds. To prepare these compounds, multi-step syntheses are required. Furthermore, in some of these syntheses, environmentally unfriendly, toxic or harmful chemical precursors are required. These two problems have significantly i...
