Powder of firecracker prepared from potassium perchlorate

Abstract

The present invention relates to a potassium perchlorate fire crackers powder. Its composition includes (by wt%) potassium perchlorate (KClO4) 38.46%-52.63%, sulfur (S) 17.39%-31.82%, aluminium powder (AL) 12.5%-23.81% and ground perlite 8.33%-15.38%. It is safe and low in cost, and its explosive effect is identical to that of potassium chlorate.

Description

technical field [0001] The invention relates to a firecracker powder, in particular to a potassium perchlorate firecracker powder. Background technique [0002] Potassium chlorate has strong oxidizing properties. When mixed with organic matter, sulfur, sulfide or other easily oxidizable substances, it may burn or explode strongly when heated, rubbed, or hit, so it is often used as an oxidant to make firecracker gunpowder. However, due to the poor stability of potassium chlorate and low melting point, it is an exothermic reaction when heated and decomposed, which seriously affects the safety of fireworks and firecrackers in production, storage, transportation and use. Compared with it, potassium perchlorate has better stability, high melting point, not easy to deliquescence, and needs to absorb heat when decomposed by heat. Using potassium perchlorate as the main component to make fireworks greatly reduces the sensitivity of fireworks and firecrackers....
