Embodiment 1

[0040] Embodiment 1 blue-green fountain cold fireworks

[0041] The formula used is: ① Ammonium perchlorate 30%, ② Nitrocellulose 20%, ③ Silver titanium powder 30%, ④ Guangzhou Tianyu Trading Co., Ltd. TYB-40 blue-green photoluminescent material 15%, ⑤ Fluorine rubber 5% ; Both are mass percentages. The production process is as follows: the first step is to prepare fuel particles, and the process is as follows: firstly mix component ③ with component ④ evenly; then use acetone to dissolve component ⑤ to form a solution; then add the solution of component ⑤ to component ③ ﹑④ in the mixed powder, mixed evenly; the mixture of components ③﹑④﹑⑤ was made into fuel particles with a particle size of 80 mesh by the spheronization method, dried at 50°C, and set aside. The second step is to mix the medicaments, that is to mix the mixed particles of components ①, ② and ③, ④, ⑤ evenly. The third step is to charge the product, and fill the uniformly mixed blue cold smoke into the fountain ...

Abstract

The invention discloses a multicolor cold-firework reagent and a manufacturing method of cold fireworks. The multicolor cold-firework reagent comprises the following components in percentage by weight: 20-30% of ammonium perchlorate, 20-30% of nitrocellulose, 30-35% of silver titanium powder, 15-20% of photoluminescence material and 5-10% of fluororubber. The manufacturing method of the spraying-decoration cold fireworks comprises the following steps: fuel granulation, reagent mixing, charging and packaging. The manufacturing method of the high-waterfall display shell cold fireworks comprises the following steps: luminescent material granulation, fuel mixing, detonating agent manufacturing and display shell filling. The cold fireworks disclosed by the invention can have multiple bright colors, thereby greatly enhancing the ornamental value of the cold fireworks.

Description

technical field [0001] The invention belongs to the technical field of civil entertainment pyrotechnics, in particular to a cold smoke flower agent and a cold smoke flower preparation method that present multi-color light when set off. Background technique [0002] Cold fireworks, also known as cold fireworks, cold fireworks, cold light fireworks, indoor fireworks, are a kind of high-end new technology civilian entertainment pyrotechnic products, often used in various celebrations or parties and other festive occasions. [0003] The combustion mechanism of cold fireworks is similar to fuel-rich propellants. The entire discharge process has experienced two combustion reactions. The first combustion is mainly the reaction between the oxidant ammonium perchlorate in the formula and the combustible nitrocellulose. Mass production of gas, the excess fuel (titanium powder, titanium alloy powder, etc.) in the formula is launched and ignited, and the combustion trajectory of the exc...
