Embodiment 1

[0028] This embodiment provides a color agent for fireworks and firecrackers, which is composed of the following components: 52 parts of potassium perchlorate, 25 parts of strontium carbonate, 33 parts of azotetrazolium diguanidine, 21 parts of 5-aminotetrazolium nitrate, chlorinated 5 parts of rubber and 5 parts of phenolic resin.

[0029] The present embodiment also provides the preparation method of the above-mentioned color medicament for fireworks and firecrackers, and the steps are as follows:

[0030] First, dry each component to a moisture content of less than 1%, and fully grind it to pass through a 60-mesh sieve;

[0031] Then weigh each component according to the dosage ratio, sieve and mix evenly with a 60-mesh sieve, and sieve and mix three times in order to ensure the uniformity of the medicament;

[0032] The mixed material was granulated while spraying absolute ethanol, and finally dried at 50°C.

Embodiment 2

[0034] This embodiment provides a color agent for fireworks and firecrackers, which is composed of the following components: 46 parts of potassium perchlorate, 20 parts of copper oxide, 29 parts of azotetrazolium diguanidine, 15 parts of 5-aminotetrazolium nitrate, chlorinated 5 parts of rubber and 5 parts of phenolic resin.

[0035] The present embodiment also provides the preparation method of the above-mentioned color medicament for fireworks and firecrackers, and the steps are as follows:

[0036] First, dry each component to a moisture content of less than 1%, and fully grind it to pass through a 60-mesh sieve;

[0037] Then weigh each component according to the dosage ratio, sieve and mix evenly with a 60-mesh sieve, and sieve and mix three times in order to ensure the uniformity of the medicament;

[0038] The mixed material was granulated while spraying absolute ethanol, and finally dried at 50°C.

Abstract

The embodiment of the invention provides a color agent for fireworks and crackers and a preparation method of the color agent, wherein the color agent does not contain metal powder, and a combustibleagent is composed of azotetrazolebiguanide and 5-aminotetrazolenitrate. According to the embodiment of the invention, the azotetrazolebiguanide and 5-aminotetrazolenitrate are compounded to replace metal powder used in the prior art, so that the explosion power of fireworks and crackers is reasonably reduced, the safety is improved, and gas is mainly generated after the azotetrazolebiguanide and 5-aminotetrazolenitrate are combusted, so that generation of solid residues is reduced and environment protection is enhanced; what is more, the azotetrazolebiguanide and 5-aminotetrazolenitrate are compounded to replace metal powder, and the overall combustion heat of the medicament can be controlled within a specific range, so that the color purity of the medicament after combustion is improved,and the ornamental effect is improved.

Description

technical field [0001] The invention relates to the technical field of fireworks and firecrackers production and processing, 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 ignition, they will burn or explode to produce light, sound, color, shape, smoke and other effects. The lack of viewing entertainment. [0003] In order to make fireworks bombs, combined fireworks and other varieties have better viewing effect when they are fired, magnesium aluminum alloy powder is often used as the flammable agent for fireworks explosion. Moreover, the combustion of magnesium-aluminum alloy powder will produce solid residues, increase the values ​​of PM2.5 and PM10 in the atmosphere, and have a great negative impact on air quality. [0004] In recent years, with the increasing requirements for environmental protection an...
