Problems solved by technology

[0002] Black powder or propellant is the main dangerous raw material for the production of fireworks and firecrackers. It is more dangerous in the process of production, storage and transportation, and is extremely prone to accidents. However, the propellant or propellant components of traditionally produced fireworks and firecrackers generally use One sulfur, two nitrate, three charcoal way
That is, potassium nitrate is more than 70%, sulfur is 10%, and the rest is charcoal, which will produce a large amount of black smoke when burned, and bring great hidden dangers to safe production
In actual production at present, the firework propellant has been using black powder (military nitrate) composed of potassium nitrate, charcoal and sulfur. It will produce a lot of smoke when burning, which will affect the effect of fireworks and leave a large amount of gunpowder in the air. The oxides and residues of carbon, sulfur, and potassium, which seriously pollute the environment

Abstract

The invention discloses a safety and environment-friendly firework composite material and a preparation method thereof. The safety and environment-friendly firework composite material is prepared fromthe following raw materials in parts by weight: modified nitrocellulose, terephthalic acid, perlite powder, modified carbon powder, potassium perchlorate, aluminum hydroxide, antistatic acrylic resin, potassium hydroxide, potassium hydrogen phthalate, a stabilizing agent, single-base powder, strong agent powder and water. The preparation method of the safety and environment-friendly firework composite material comprises the steps of preparation of raw materials, preparation of dispersion liquid, preparation of composite materials, forming and filling of shoot chargepropellant for fireworks. According to the preparation method disclosed by the invention, by taking the modified nitrocellulose, the perlite powder and the modified carbon powder as main raw materials, the smoke occurrence quantity and the amount of air residues are extremely small during combustion and no smoke is produced through visual inspection; in addition, the smoke does not contain sulfide and does not produce sulfide exhaust gas after combustion, so that good environmental protection performance is achieved; meanwhile, the modified nitrocellulose, the perlite powder and the modified carbon powder are combined to realize good moisture-proof performance; the propellanta drug is stable and can be stored and transported for a long time; besides, the safety of production storage and transportation is ensured.
