Abstract

The invention relates to a thermostable indoor set-off smokeless sulfur-free cold firework medicament and a preparation method thereof, and belongs to the field of environment-friendly pyrotechnic compositions. The firework medicament is composed of the components: nano titanium-magnesium powder, modified pentaerythritol tetranitrate, zirconium deuteride, dihydroxy glyoxime, nitrobamboo cellulose,dimethyl diphenyl urea, zinc stearate, nitro tert-butyl triol trinitrate, polyethylene wax and diatomite. The nano magnesium-aluminum powder and the modified pentaerythritol tetranitrate powder are used as main components, so that the setting-off temperature is low, and safety and reliability are realized; dihydroxy glyoxime and zirconium deuteride are introduced, so that sufficient combustion and bright color are ensured; the components do not contain chlorine elements and sulfur elements, so that no toxic and harmful smoke is generated; self-made nitrated bamboo cellulose is adopted, and dimethyl diphenyl urea is introduced, so that the compatibility and the mechanical property of the cold firework medicament can be effectively improved, the safety performance of the cold firework medicament is remarkably improved, the safety and the reliability of the cold firework medicament are guaranteed, and an excellent setting-off effect is achieved.

Description

technical field [0001] The invention relates to a heat-stable indoor discharge smokeless and sulfur-free cold fireworks agent and a preparation method thereof, belonging to the field of environment-friendly pyrotechnics. Background technique [0002] The development of cold fireworks is a new trend in the future development of the fireworks industry. It has the advantages of environmental protection and low discharge temperature, and has strong competitiveness in the market; moreover, the advantages of cold fireworks in indoor discharge are incomparable to other fireworks. Whether it is in large-scale fireworks parties, wedding celebrations, stage modeling, or in bars and KTVs, there are always cold fireworks. There is no doubt that cold fireworks have broad market prospects and huge economic benefits. [0003] As we all know, the main ingredients of today's cold smoke flowers are ammonium perchlorate, nitrocellulose and low ignition point metal powder. Its discharge will ...
