Embodiment 1

[0026] This embodiment provides a method for making special gunpowder for painting with red gunpowder. The raw material components include:

[0027] 48 parts by weight of ferric nitrate

[0028] Combustible agent: a mixture of TNT and RDX in a mass ratio of 60:40, 50 parts by weight

[0029] Burning rate regulator: lead azide, 2 parts by mass

[0030] Further, this embodiment provides a method for making red gunpowder special gunpowder for painting, including the following steps:

[0031] Said nitrate is weighed and pulverized to obtain nitrate fine powder;

[0032] Weigh the required amount of TNT, melt it in a water bath at 90 degrees Celsius, then add the required amount of RDX, and stir slowly to obtain a uniformly mixed solution;

[0033] Add the nitrate fine powder obtained in step (1) into the melted combustible agent, stir slowly to make it evenly mixed; make the pattern to be drawn by the obtained mixed solution, and slowly wait for it to solidify naturally;

Abstract

The invention relates to a special gunpowder formula for firework colored drawing and special paper for firework colored drawing. According to the special gunpowder formula, gunpowder special for colored drawing is finally prepared from the raw materials such as nitrate, a combustible agent and a combustion speed regulator through proper proportioning. According to the special paper for firework colored drawing, flame retardant technologies are added on the basis of the common paper, so that the paper can resist high temperature and can be applied to firework colored drawing conveniently. Thespecial gunpowder can combust rapidly after being ignited, the produced temperature enables the added nitrate to be decomposed into the corresponding metal oxide, the oxide corresponding to the selected nitrate is nonferrous metal oxide, and the metal oxide generated through reaction firmly adheres to the special paper; furthermore, any adverse damage to the paper by the produced temperature is avoided. The defect that the traditional firework colored drawing has single color is overcome, so that spreading and development of the firework drawing are facilitated.

Description

technical field [0001] The invention belongs to the technical field of pyrotechnic painting, in particular to a special gunpowder formula for pyrotechnic painting and special paper for pyrotechnic painting. Background technique [0002] With the rapid development of our country's economy, our people's pursuit of art is gradually increasing. Painting can improve people's self-cultivation, cultivate people's sentiments, open people's horizons, and let you really see what is beauty and what people are pursuing. But because the painting process is boring, few people can calm down. Therefore, new ways of painting urgently need to be withdrawn. The painting process of pyrotechnic painting has excellent ornamental value, which can add some fun to people's boring life, but traditional pyrotechnic painting cannot be further promoted because of the monotonous color. In addition, the paper used in pyrotechnic paintings needs to be resistant to high temperatures, and ordinary paper c...
