Abstract

The invention relates to a smokeless emission chemical for fireworks. The smokeless emission chemical consists of the following components in parts by weight: 20-120 parts of nitrocellulose, 5-10 parts of graphite, 5-25 parts of carboxymethylcellulose, 3-40 parts of charcoaled hemp stalk powder, 3-40 parts of charcoaled fir powder, 2-30 parts of ammonium dichromate, 10-30 parts of barium nitrate and 5-40 parts of potassium perchlorate. The smokeless emission chemical produces smoke only after being burnt, which is 80% less than that of fireworks made from conventional materials; the smokeless emission chemical is free from sulfur dioxide, and the riction sensitivity, collision degree, heat absorption, wet absorption and compatibility are superior to those of the common military saltpeter.

Description

[0001] technical field

[0002] The invention relates to a pyrotechnic composition, in particular to a micro-smoke propellant agent for fireworks. Background technique

[0003] In the prior art, the propellant used for fireworks mostly produces smog, and simultaneously produces sulfur dioxide and sulfur trioxide. Due to the large smoke, the effect of the large-scale fireworks that are set off is seriously affected, and it causes great pollution to the urban air near the discharge site, and is sensitive to safety and stability, and has the phenomenon of rapid combustion and rapid explosion. Contents of the invention

[0004] The object of the present invention is to provide a kind of propellant for fireworks with little smoke and no sulfur dioxide after burning, and which can maintain various safety indicators.

[0005] The micro-smoke propellant agent for fireworks provided by the present invention comprises the following components in parts by weight: 20-120 parts of...
