Problems solved by technology

[0005] Because the burning light color of cold smoke flowers is determined by metal fuel, and the metal fuels that can be used for cold smoke flowers are only titanium powder, titanium alloy powder, iron powder, carbon particles, etc., so the color of cold smoke flowers currently on the market is only silver. , gold, golden red and dark red are limited, and the color is monotonous, not as rich as ordinary colored light fireworks, which cannot meet the needs of customers for various viewing colors of cold fireworks
[0006] Therefore, the problem that the prior art exists is how to get more colorful cold fireworks

Embodiment 1

[0031] The formula used is: boron powder 25%, magnesium aluminum alloy powder 8%, titanium powder 12%, barium nitrate 15%, 52# chlorinated paraffin 10%, nitrocellulose 15%, ammonium perchlorate 15%, all of which are quality percentage. The preparation process of the medicament is as follows: first, mix the first four materials boron powder, magnesium aluminum alloy powder, titanium powder, and barium nitrate; then add the fifth material 52# chlorinated paraffin and mix evenly; mix the first five materials The material is granulated into 40-mesh granules by spheronization, and dried at 40°C; then the dried fuel granules are mixed evenly with the remaining two materials, nitrocellulose and ammonium perchlorate. The mixture containing all the components is the bright green cold smoke flower agent, which can be divided into different cold smoke flower products.

Embodiment 2

[0033] The formula used is: boron powder 40%, magnesium aluminum alloy powder 6%, titanium powder 8%, barium nitrate 8%, 52# chlorinated paraffin 6%, nitrocellulose 15%, ammonium perchlorate 17%, all of which are quality percentage. The preparation process of the medicament is as follows: first, mix the first four materials boron powder, magnesium aluminum alloy powder, titanium powder, and barium nitrate; then add the fifth material 52# chlorinated paraffin and mix evenly; mix the first five materials The material is granulated into 60-mesh granules by extrusion method, and dried at 40°C; then the dried fuel granules are mixed evenly with the remaining two materials, nitrocellulose and ammonium perchlorate. The mixture containing all the components is the bright green cold smoke flower agent, which can be divided into different cold smoke flower products.

Embodiment 3

[0035] The formula used is: boron powder 28%, magnesium aluminum alloy powder 10%, titanium powder 8%, barium nitrate 8%, 52# chlorinated paraffin 11%, nitrocellulose 15%, ammonium perchlorate 20%, all of which are quality percentage. The preparation process of the medicament is as follows: first, mix the first four materials boron powder, magnesium aluminum alloy powder, titanium powder, and barium nitrate; then add the fifth material 52# chlorinated paraffin and mix evenly; mix the first five materials The material is granulated into 50-mesh granules by spheronization, and dried at 40°C; then the dried fuel granules are mixed evenly with the remaining two materials, nitrocellulose and ammonium perchlorate. The mixture containing all the components is the bright green cold smoke flower agent, which can be divided into different cold smoke flower products.

Abstract

The invention discloses a bright green cold firework composition and a preparation method thereof. The composition comprises the following ingredients by weight percentage: 25-40% of boron powder, 5-15% of magnalium powder, 6-12% of titanium powder, 8-15% of barium nitrate, 6-10% of 52# chlorinated paraffin, 15-20% of nitrocotton and 15-20% of ammonium perchlorate. The preparation method of the composition comprises the steps of fuel mixing, fuel granulation, fuel grain drying and composition mixing. A cold firework produced by the composition can emit bright green light, the color variety of the cold firework is enriched, and the enjoyment effect of the cold firework is improved.

Description

technical field [0001] The invention belongs to the technical field of civil entertainment pyrotechnics, in particular to a bright green cold smoke flower agent with boron as the main luminescent component and a preparation method thereof. Background technique [0002] Cold fireworks are also called cold fireworks, cold fireworks, cold light fireworks, indoor fireworks, etc. They are civilian entertainment pyrotechnic products produced by high-tech. After the products are lit, the flame temperature is low, and the flame can be directly touched by hand, so it is called "cold". fireworks. Cold fireworks have a low combustion temperature and are safer than conventional fireworks products. High-end cold fireworks products can be basically smokeless and tasteless when they are set off. They are suitable for various occasions and can be set off indoors. Their application is being vigorously promoted. [0003] The formula of cold smoke flowers generally includes oxidizers (such as...
