The present invention discloses explosive black powder that is used for fireworks. The black powder contains the following components with the following weight portions: 40 to 75 portions of potassium perchlorate, 0 to 35 portions of potassium nitrate, 1 to 5 portions of potassium dichromate, 5 to 15 portions of sulfur, 5 to 25 portions of charcoal, 0.5 to 2 portions of carbon black, and 5 to 20 portions of potassium terephthalic acid or potassium acid phthalate. The explosive black powder is made of the components according to the ratio. No metal material or toxic substances are used. The explosive black powder has the advantages of low mechanical sensitivity, excellent stability, large explosive scale, excellent explosive sound, black medicine, easily prepared raw materials and relatively low cost. Thus the explosive black powder is the ideal explosive black powder.

The embodiments of the present invention provide a color agent for fireworks and firecrackers and a preparation method thereof. The color agent for fireworks and firecrackers does not contain metal powder, wherein the combustible agent is composed of azotetrazolium biguanide and 5-aminotetrazole nitrate. The color agent for fireworks and firecrackers provided by the embodiment of the present invention replaces the metal powder used in the prior art by compounding azotetrazolium diguanidine and 5-aminotetrazole nitrate, which not only reasonably reduces the explosive power of fireworks and firecrackers, but also improves safety. properties, and the combustion of azotetrazolium diguanide and 5-aminotetrazole nitrate is mainly gas, which reduces the generation of solid residues and improves environmental protection. More importantly, the use of azotetrazolium diguanidine and The 5-aminotetrazole nitrate compound replaces the metal powder, which can control the overall combustion heat of the agent within a specific range, thereby improving the color purity of the agent after burning and improving the ornamental effect.
