Novel explosive firework chemical agent

Abstract

The invention discloses a novel explosive firework chemical agent. The novel explosive firework chemical agent is characterized by comprising the following components in percentages by mass: 5-70% ofnitrostover, 5-30% of nickel nitrate, 5-20% of hydrazine hydrate, 10-25% of zirconium silicate, 2-5% of sodium silicate and 8-15% of carbon black. The nitrostover is prepared by using a secondary acidification method and a ternary nitro reaction method. The product is mainly used for preparing micro-smoke materials and cold-light fireworks in the technical field of fireworks. The novel explosive firework chemical agent has good impact and friction sensitivity and good thermal stability, meanwhile is low in moisture rate, not only is convenient to transport and store, but also is safe and environmentally friendly, and is simple to prepare and low in production cost.

Description

technical field [0001] The invention relates to a novel cracking fireworks medicament, which belongs to the field of fireworks medicine. Background technique [0002] In the prior art, the medicine used for preparation in traditional fireworks and firecrackers is generally formulated with sulfur, or a mixture of sulfur-containing medicines and potassium chlorate or potassium perchlorate and potassium nitrate as oxidants. These sulfur-containing and potassium salts Although the above-mentioned drugs have good detonation performance, the above-mentioned agents decompose into metal oxide particles when they are burned. Due to the thermal decomposition effect, their sensitivity is very high. And because the smog that produces is thick, causes setting off viewing and viewing effect is poor, also can have metal residue suspended matter to exist in the air after setting off, seriously pollutes environment, encroaches on human health. [0003] For this reason, many fireworks produc...

[0002] In the prior art, the medicine used for preparation in traditional fireworks and firecrackers is generally formulated with sulfur, or a mixture of sulfur-containing medicines and potassium chlorate or potassium perchlorate and potassium nitrate as oxidants. These sulfur-containing and potassium salts Although the above-mentioned drugs have good detonation performance, the above-mentioned agents decompose into metal oxide particles when they are burned. Due to the thermal decomposition effect, their sensitivity is very high. And because the smog produced is thick and heavy, the viewing effect of setting off is poor, and there will be metal residues suspended in the air after setting off, seriously polluting the environment and infringing on human health.

[0003] For this reason, many fireworks production enterprises have invested a lot of manpower and material resources to improve and develop the traditional cracking agent formula used in fireworks, and some have applied for a lot of patents. The reason is that the production cost of the new alternative agent is high, the discharge effect is single, and there are still a lot of smoke and metal residues
