Problems solved by technology

Potassium nitrate is used as the oxidizing agent in the traditional firework brightening agent, and potassium nitrate is used as the oxidizing agent in modern times. Because the thermal stability of these two oxidizing agents is very poor, it is very easy to cause safety accidents. In 2002, the General Office of the State Council 52 The document No. 1 even stipulates that the use of potassium chlorate is strictly prohibited in the production of fireworks and firecrackers; at the same time, a large amount of sulfur is used as a reducing agent, and sulfur itself is a combustible substance with very active chemical properties, which further reduces the stability of the agent. Toxic and harmful sulfur dioxide gas affects the environment, so the country restricts its use; therefore, a more environmentally friendly and safer firecracker is needed

Abstract

The invention provides a safe environment-friendly colorful firecracker reagent and a method for preparing a colorful firecracker by using the reagent. The colorful reagent comprises a component A and a component B. The manufacturing technique is implemented by coating the component B on the component A. The reagent is free of potassium chlorate or any other national forbidden component, and is free of sulfides. In the firecracker prepared by the method, the component A is coated with the component B, and the component B has the functions of heat insulation, water resistance, collision prevention and the like, thereby overcoming the defect that the component A can be easily moisturized, can be easily exploded by impact, can easily generate spontaneous combustion due to high temperature and the like. Thus, the firecracker has the characteristics of high reaction speed, clear sound, multiple colors, low impact sensitivity, low friction sensitivity, low flame sensitivity, high ignition temperature, high safety, no sulfur and the like.

Description

technical field [0001] The invention belongs to the field of chemical and chemical gunpowder preparation, and in particular relates to a safe and environment-friendly colorful firecracker medicament and a method for preparing colorful firecrackers with the medicament. Background technique [0002] Firecrackers and fireworks are one of the commonly used festive items for people. Whether it is Chinese New Year, wedding, school promotion, summer completion, or store opening, the metropolis will set off firecrackers and fireworks to celebrate. Potassium nitrate is used as the oxidizing agent in the traditional firework brightening agent, and potassium nitrate is used as the oxidizing agent in modern times. Because the thermal stability of these two oxidizing agents is very poor, it is very easy to cause safety accidents. In 2002, the General Office of the State Council 52 The document No. 1 even stipulates that the use of potassium chlorate is strictly prohibited in the producti...
