Problems solved by technology
[0003] ① Potassium chlorate has an extremely low melting point, exothermic heat, and is easy to decompose. In addition, when it is compatible with sulfur, the mechanical sensitivity of the mixed agent is high, so it is very easy to explode during the production, storage, and transportation of fireworks and firecrackers. Explosion accidents account for 60-70% of total accidents
[0004] ② Using a single potassium perchlorate as an oxidant, although the safety factor is higher than that of potassium chlorate, there are many inconveniences and disadvantages in use, such as firecrackers are difficult to catch fire, the burning speed is slow, the price is high, and it is difficult for enterprises to accept

An oxidant of firecracker consists of potassium perchlorate 20-40wt%, nitrate 30-50wt%, passive filler 5-20wt% and active agent 5-10wt%. It achieves better safety, low cost, no pollution, stable physic and chemical performances and good hear-resisting property.
Description
technical field [0001] The invention relates to an oxidizing agent in fireworks and firecrackers. Background technique [0002] Potassium chlorate and potassium perchlorate are commonly used as oxidizing agents in the production of fireworks and firecrackers. Compatible with aluminum powder (aluminum-magnesium alloy powder) and sulfur as a mixed agent. But there are certain defects. Such as: [0003] ①Because of the extremely low melting point of potassium chlorate, it exothermic itself and is easy to decompose. In addition, when it is compatible with sulfur, the mechanical sensitivity of the mixed agent is high, so it is very easy to explode during the production, storage and transportation of fireworks and firecrackers, and the fireworks and firecrackers caused by this Explosion accidents account for 60-70% of the total accidents. For this reason, the State Council issued Guobanfa [2002] No. 52 document in 2002, prohibiting the use of potassium chlorate in fireworks an...
