Abstract

The invention relates to a multifunctional smoke-free non-sulfur firecracker propellant and a preparation method thereof and belongs to the field of environment-friendly pyrotechnic compositions. Thefirecracker propellant includes: nitro-bamboo cellulose, passivated hexogen, nitroguanidine, nano boron powder, KNO3, NH4NO3, a component A, diphenyl urea, phenyl silicone oil, potassium sorbate, sodium hexametaphosphate, kasugamycin, meso-porous SiO2, functional carboxylated multiwall carbon nanotubes, and single-layer graphene oxide. The firecracker propellant is high in launch height during setting off, is smoke-free and residue-free, satisfies the demand of environment-friendly pyrotechnic compositions and is improved in comprehensive performances such as moisture absorption, corrosion resistance, antistatic effect thereof on the basis of ensuring normal performances of the firecracker propellant.

Description

technical field [0001] The invention relates to a multifunctional smokeless and sulfur-free firecracker propellant 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. "China Industrial History" wrote that fireworks "beginning in Tang Dynasty, flourishing in Song Dynasty, and originating in Liuyang". In various festivals, parties or other activities, the use of fireworks is enormous. [0003] At present, the propellants commonly used in the fireworks industry all over the country and around the world are mainly made of military nitrate, including potassium nitrate, charcoal, sulfur and metal powder. Its discharge will produce a lot of smoke, sulfur dioxide and its oxides, metal oxide dust, etc.; at the same time, there will be a large amount of carbon, sulfur, potassium oxides and solid residues left after the discharge. This not only se...
