Technical Field
The invention relates to the technical field of firework preparation, in particular to a firework using recovered copper slag residual tailings as a color former.
Background
Fireworks and firecrackers are set off on festival days, so that festival atmosphere is created, and the festival is a traditional custom of Chinese people. The traditional fireworks products are similar and different, and all contain black powder, powder guiding and effect powder, and are added with some luminescent agents and chromophoric agents, so that the fireworks products can present colorful colors.
However, in the prior art, the used color former is mainly alloy powder and heavy metal ion salts such as copper salt, strontium salt, barium salt, nickel salt and the like. The price is high, the residue is large after the ignition, and the heavy metal ion salts remained after the combustion are a large pollution hidden trouble to the environment. Especially, after the gas is set off, the residue is broken due to the impact of explosion force to form smoke of PM2.5, which is extremely not beneficial to air quality and environmental protection, and has great harm and threat to human body.
In the existing industrial and mining enterprises, a large amount of smelting waste residues exist in the smelting industry, such as copper smelting slag. The copper slag contains various heavy metals and precious metals and has a recycling value. In the existing enterprises for refining copper slag, after high value-added metals such as gold and silver are refined and copper concentrate is enriched and recovered, the residual tailings are mostly silicate, contain a small amount of copper, have low taste and are difficult to continuously recycle.
The method utilizes the recycled copper slag residual tailings as the raw material to prepare the firework color former particles, replaces the traditional color former, has better effect and realizes resource recycling; the prepared firework color former particles can improve the diameter of the flare of the firework, and are good in hydrophilicity and easy to settle.

the fireworks prepared in the examples and comparative examples with the same specification are subjected to a firework setting-off effect test: the invention mainly observes the effects of burning off as color effects, including color, brightness degree, diameter of light flame, size of smoke dust after burning off and dissipation speed of smoke dust;
the size of smoke dust after burning: the fireworks prepared in each embodiment and comparative example are put into a safe and closed spherical explosion-proof tank to be detonated, a smoke density box luminometer is used for carrying out luminousness detection, and the higher the luminousness is, the smaller the smoke dust is after the fireworks are set off;
soot dissipation speed: keeping the spherical explosion-proof tank sealed, detecting the light transmittance by using a smoke density box light transmittance instrument, recording the light absorbance (the light absorbance = 1-light transmittance), continuously testing, recording a half-decay period required when the light absorbance becomes the original light absorbance 1/2, wherein the shorter the half-decay period is, the faster the smoke dust dissipation speed is;

And copper salt is not used as a color former, so that the residual influence of the heavy metal ions after burning is reduced, and the environment is benefited. Meanwhile, the prepared color former is in a particle formulation, is different from a metal salt color former, is easy to gasify and sublimate, has larger diameter of a flare when being set off, has better persistence, and is particularly suitable for fireworks with spray patterns, tiger tail effect types and the like.
After the firework is set off, the residual particles have strong hydrophilicity and are quickly settled, the metal salt residues and PM2.5 particulate pollutants which are difficult to settle in the air are greatly reduced, and the effect of preventing the air pollution after the firework is set off is obvious. Meanwhile, the copper content is low, the influence on the whole environment is small, and the copper is one of essential nutrient elements of plants, so the influence on the ecological environment is extremely low. The invention has the advantages that the resource of the industrial and mining residual tailings is recycled, and the generated environmental protection effect is very obvious.
