Example Embodiment

[0008] The present invention will be further described below in conjunction with specific embodiments:

[0009] Examples of the formula of firecracker powder: 150 grams of potassium perchlorate; 420 grams of barium nitrate; 30 grams of perlite powder; 100 grams of magnesium aluminum alloy powder; 80 grams of aluminum powder; 160 grams of titanium powder; and 60 grams of sulfur. The potassium perchlorate and barium nitrate are respectively sieved and crushed, and then perlite powder is added and mixed uniformly to obtain the oxidant for firecrackers; in addition, magnesium-aluminum alloy, aluminum powder, titanium powder, and sulfur are respectively screened; the sieved powder is sieved and then dried After mixing uniformly, the reducing agent for firecrackers is obtained; the obtained oxidizing agent and reducing agent are carefully mixed uniformly by a dry method to obtain the finished firecracker powder.

[0010] The firecracker powder of the present invention uses titanium powde...

Abstract

The invention relates to a formula of firecracker. The formula of firecracker contains 10-20% of potassium perchlorate, 35-50% of barium nitrate, 1-8% of perlite powder, 5-20% of magnesium aluminium alloy, 3-15% of aluminium powder, 10-25% of titanium powder and 3-10% of brim stone. The formula of firecracker of the invention contains no forbidden chemical such as potassium chlorate and the like and reduces medication cost when potassium perchlorate is used as oxidant. The invention is applicable to novel firecracker produced on a large scale by mechanization operation. In addition, the invention has safe technology, high yield and good product quality and overcomes defects of fire cutoff and single setting off effect of traditional firecracker.

Description

technical field [0001] The invention relates to a formula of firecracker medicine. technical background [0002] China's existing traditional firecrackers only have a single flash and sound effect, and have always stagnated at the discharge effect of the electric light cannon in the early 1980s, and the discharge effect is single and dull. Potassium chlorate is the most commonly used oxidant in the production of fireworks and firecrackers. It is a strong oxidant. Its thermal decomposition process is an exothermic reaction, with low decomposition temperature and good flammability. , Fireworks and firecrackers using potassium chlorate as an oxidant have a better discharge effect, but after the mixed agent composed of potassium chlorate and sulfur or sulfide is put into use, not only the incidence of accidents increases, but also the destructive power of accidents increases greatly. Therefore, it is listed as a prohibited drug by the state. Invention content: [0003] The p...
