Abstract

The invention relates to an antistatic, smokeless and sulfur-free propellant for fireworks, and a preparation method thereof, and belongs to the field of environmentally-friendly pyrotechnic compositions. The propellant is prepared from nitrified bamboo cellulose, glycidyl azide polymer, potassium nitrate, a component A, a component B, modified graphene oxide, multi-walled carbon nanotubes, hydrogen-containing silicone oil, ursolic acid and tebufenpyrad. The antistatic, smokeless and sulfur-free propellant for fireworks has the advantages of good stability, high emission height during settingoff, no smoke, no residues, meeting the requirements of an environmentally-friendly pyrotechnic composition, and good antistatic, antioxidant and anticorrosive properties, and can be widely applied tovarious firework products. The preparation method has the advantages of simple process, easily available raw materials and suitableness for large-scale production.

Description

technical field [0001] The invention relates to an antistatic smokeless and sulfur-free propellant for fireworks and a preparation method thereof, belonging to the field of environment-friendly pyrotechnics. Background technique [0002] Our country has a long history of developing and using fireworks. With the continuous improvement of people's living standards, the demand for fireworks is increasing day by day. In various festivals, parties or other activities, the use of fireworks is huge. [0003] At present, the propellants commonly used in the fireworks industry are mainly made of military nitrate, including potassium nitrate, charcoal, sulfur and metal powder. Its discharge will produce a lot of smoke and metal oxide dust, causing serious environmental pollution and endangering human health; it also seriously affects the lift-off characteristics and discharge effect of fireworks; after discharge, there are still a large amount of oxides of carbon, sulfur, potassium an...
