Abstract

The invention relates to a low-sensitivity environment-friendly firework chemical and a preparation method thereof, and belongs to the technical field of civil entertainment fireworks. The preparationmethod comprises the steps: weighing nitrocellulose, dicyandiamide, modified graphite, titanium powder, rare earth photoluminescent powder and a binder; dissolving dicyandiamide in hot water to prepare a dicyandiamide solution, loading the dicyandiamide solution into a sprinkling can, and sprinkling the dicyandiamide solution onto uniformly laid modified graphite; turning over the modified graphite powder while sprinkling, and ensuring uniform spraying; and after completion of sprinkling, drying to obtain dicyandiamide / modified graphite powder; dropwise adding an adhesive into uniformly mixedtitanium powder and rare earth photoluminescent powder, kneading uniformly, sieving and drying to obtain the luminous granulation powder; and mixing nitrocellulose, the dicyandiamide / modified graphite powder and the luminous granulation powder, and granulating to obtain the low-sensitivity environment-friendly firework chemical. The low-sensitivity environment-friendly firework chemical providedby the invention is low in sensitivity and excellent in production, storage and transportation safety performance; raw materials are easily available and the cost is low; and the setting-off process is smokeless, sulfur-free, green and environment-friendly.

Description

technical field [0001] The invention relates to a low-sensitivity environment-friendly fireworks medicament and a preparation method thereof, belonging to the technical field of civil entertainment fireworks. Background technique [0002] Fireworks have a long history in our country and are one of the representatives of Chinese traditional culture. They are necessary for auspicious and festive festivals, and they continue to develop in the long river of history. Nowadays, new requirements are put forward for the development of fireworks medicaments. [0003] As we all know, the current development of the fireworks industry is struggling, and the country also enforces bans and restrictions on releases; and the common people also have resistance to fireworks. The reason is mainly caused by two major factors: safety and the environment. On the one hand, traditionally, fireworks chemicals have the characteristics of high sensitivity, and there are great safety hazards in the pr...
