Problems solved by technology

In the known technology, the used medicament of existing fireworks and firecrackers is potassium chlorate, sulfur, aluminum powder on the last section medicine that mainly adopts such as double-ring firecrackers (two-ring guns, two kicks), and the next section medicine is fire nitrate or potassium nitrate and sulfur, Charcoal powder is prepared as a raw material. Due to the extremely unstable composition of potassium chlorate, sulfur and aluminum powder, the mechanical sensitivity is low. During the preparation, processing or storage and transportation, it is easy to cause combustion and explosion due t...

Abstract

The present invention is one kind of combined chemical for fireworks and its preparation process, and aims at providing one kind of combined chemical for fireworks possessing high heat stability, high mechanical sensitivity and high safety for compounding, producing, storing and transporting. It is ignited only in burning its fuse. The combined chemical consists of oxidant of barium nitrate and/or potassium nitrate; and inflammable including one or several of sulfur, aluminum powder, Al-Mg alloy powder, charcoal powder, titanium powder, coal powder, alumina slag, iron slag, carbon slag, resin and starch dextrin in the ratio of 100 to 10-120. It may also contain coloring agent of barium nitrate, strontium nitrate, copper carbonate and/or sodium oxalate; and effect chemical comprising sounder and color bead.

Description

technical field [0001] The invention relates to a medicament for fireworks and firecrackers and a preparation method thereof, in particular to a combined medicament for spraying fireworks and double-sound firecrackers and a preparation method thereof. Background technique [0002] Along with the improvement day by day of people's living standard and the continuous development of science and technology, the safety, entertainment and technical requirements of fireworks and firecrackers used in festivals and other occasions are also getting higher and higher. In the known technology, the used medicament of existing fireworks and firecrackers is potassium chlorate, sulfur, aluminum powder on the last section medicine that mainly adopts such as double-ring firecrackers (two-ring guns, two kicks), and the next section medicine is fire nitrate or potassium nitrate and sulfur, Charcoal powder is prepared as a raw material. Due to the extremely unstable composition of potassium chlor...
