Abstract
Description
Technical field
[0001] The invention relates to the field of chemical engineering, in particular to an environment-friendly and safe fireworks and firecracker gunpowder oxidizer used in the fireworks and firecrackers industry. Background technique
[0002] Fireworks and firecrackers originated in China, and the gunpowder used is black powder, one of the four great inventions in ancient China. Because black powder contains potassium nitrate and sulfur, its stability is poor, and it is easy to cause safety accidents. limited use. Modern gunpowder uses potassium chlorate as an oxidizing agent, and the firecrackers made of this kind of gunpowder react quickly and make loud noises. However, since potassium chlorate is a strong oxidizing agent, it has a low melting point and poor thermal stability. Its Taman temperature is 42°C and its decomposition temperature is 360°C. ℃, potassium chlorate is mixed with flammable materials such as sulfur, phosphorus, carbon, etc., and it is ea...

Embodiment Construction
[0016] Below in conjunction with embodiment, the present invention will be further described.
[0017] Take 70 grams of fine powdered potassium perchlorate, 5 grams of strontium nitrate, 5 grams of barium nitrate, 20 grams of perlite powder, and then add 35 grams of reducing agent aluminum silver powder. Gently mix evenly, this dose of gunpowder can be filled with 1260 special red firecrackers (note: 1.1 cm in diameter, 3.2 cm in length), charge, insert and seal according to conventional methods.
