Abstract

The invention discloses a pyrotechnic composition of black snakelike fireworks. The pyrotechnic composition of the black snakelike fireworks is prepared from the following raw material components in parts by weight: 8-20 parts of naphthol, 2-4 parts of linseed oil, 6-10 parts of fuming nitric acid, 3-5 parts of additives, 0.1-0.15 part of barium carbonate, 0.5-1 part of a lubricating agent and 1-3parts of natural plant glue. When the pyrotechnic composition of the black snakelike fireworks is ignited, star-shaped grains can expand and extend to 20-25 times of the original volume; when the pyrotechnic composition is burnt, black giant-snake-shaped remains are produced, snakeskin is smooth and bright and has coke-like gloss, a whole snake body is soft and elastic, and the appearance is interesting; the sensitivity of the pyrotechnic composition is low; no toxic gas is produced after burning; the pyrotechnic composition is suitable for being discharged in daytime or indoor; the defect ofdim hue of common fireworks during diurnal discharging is made up; and the joy of discharging the fireworks in daytime or indoor of a user is met.

Description

technical field [0001] The invention relates to pyrotechnic powder for black serpentine fireworks, which belongs to the technical field of fireworks production. Background technique [0002] Fireworks have been loved by people since they were produced, and have been widely used in people's lives. Especially on festivals, the display of fireworks can increase people's joy; general fireworks are composed of fuses, gunpowder and pain relievers; It can make a loud noise or produce fireworks of various colors, but all the colors or sound effects it sends will end with the end of the firing process; and the existing fireworks can produce bright colors when they are fired at night or in a dark environment. However, when setting off during the day, affected by the external light source, the colored patterns produced by the burning of the fireworks are not obvious, which reduces the entertainment; and the patterns produced by the existing fireworks are too single, and the interest ne...
