Embodiment 1
[0028] This embodiment provides a color agent for fireworks and firecrackers, which consists of the following components: 52 parts of potassium perchlorate, 25 parts of strontium carbonate, 33 parts of azotetrazolium biguanide, 21 parts of 5-aminotetrazole nitrate, 5 parts rubber and 5 parts phenolic resin.
[0029] This embodiment also provides a preparation method of the above-mentioned color agent for fireworks and firecrackers, the steps are as follows:
[0030] First dry each component until the water content is less than 1%, and fully grind to pass through a 60-mesh sieve;
[0031] Then take each component according to the dosage ratio, sieve and mix evenly with a 60 mesh sieve, in order to ensure that the medicament is even, sieve and mix three times;
[0032] The mixed material was granulated while spraying with absolute ethanol, and finally dried at 50°C.
Embodiment 2
[0034] This embodiment provides a color agent for fireworks and firecrackers, which consists of the following components: 46 parts of potassium perchlorate, 20 parts of copper oxide, 29 parts of azotetrazolium biguanidine, 15 parts of 5-aminotetrazole nitrate, 5 parts rubber and 5 parts phenolic resin.
[0035] This embodiment also provides a preparation method of the above-mentioned color agent for fireworks and firecrackers, the steps are as follows:
[0036] First dry each component until the water content is less than 1%, and fully grind to pass through a 60-mesh sieve;
[0037] Then take each component according to the dosage ratio, sieve and mix evenly with a 60 mesh sieve, in order to ensure that the medicament is even, sieve and mix three times;

Abstract
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.
Description
technical field [0001] The invention relates to the technical field of production and processing of fireworks and firecrackers, in particular to a color agent for fireworks and firecrackers and a preparation method thereof. Background technique [0002] Fireworks and firecrackers are made of pyrotechnic powder as the main raw material. After being ignited, they burn or explode to produce effects such as light, sound, color, shape, and smoke. The best ornamental entertainment. [0003] In order to have a better viewing effect when fireworks bombs and combined fireworks are set off, magnesium-aluminum alloy powder is often used as the combustible agent for fireworks. High; and the combustion of magnesium-aluminum alloy powder will produce solid residues, which will increase the value of PM2.5 and PM10 in the atmosphere, and have a great negative impact on air quality. [0004] In recent years, as people's requirements for environmental protection have become higher and highe...
