Problems solved by technology

However, there is an insurmountable disadvantage in the application of nitrate combination materials, that is, the nitrate combination compounds all contain nitrate anions, and the hygroscopicity of nitrate anions makes the prepared pyrotechnic powder easy to deliquescence and deteriorate, which affects the product. Mass can't even set off

Abstract

The invention discloses a high-safety environment-friendly nitrate fireworks which comprise the following components: potassium perchlorate, ammonium nitrate, hydrazine nitrate, guanidine nitrate, nitrocellulose, magnesium oxide, barium oxide, copper chloride and an additive, and a preparation method of the additive comprises the following steps: weighing multi-walled carbon nanotubes, adding the multi-walled carbon nanotubes into triethylene glycol, stirring a solution, carrying out ultrasonic treatment for 5-10 minutes, then adding ruthenium acetylacetonate into the solution in a stirring state to form a mixture, heating the mixture to 250-270 DEG C, keeping the temperature for 20-30 minutes, air-cooling the mixture to normal temperature after keeping the temperature, putting the mixture into a vacuum furnace, vacuumizing, heating and evaporating to remove triethylene glycol, cooling the remainder to normal temperature along with the furnace in a vacuum environment, and taking out to obtain the additive. Nitrate compounds in the fireworks are modified, the hygroscopicity of the fireworks is greatly reduced, and the problem that pyrotechnic compositions are prone to deliquescence and deterioration is solved.

Description

technical field [0001] The invention relates to the technical field of fireworks and firecrackers, in particular to a high-safety and environment-friendly nitrate-based fireworks and a production method thereof. Background technique [0002] Fireworks and firecrackers are made of pyrotechnic powder as the main raw material. After being ignited, they burn or explode to produce effects such as light, sound, color, shape, and smoke. The lack of ornamental entertainment. [0003] The safety and environmental protection performance of the existing fireworks and firecrackers is poor, which is reflected in the following aspects: the sulfide produced by the discharge causes serious environmental pollution; the ammonia nitrogen gas causes the greenhouse effect; the dust problem caused by the metal powder easily causes occupational diseases such as silicosis of the production personnel, and Dust is easy to cause explosion, and aluminum and magnesium metal powders are easy to react wi...
