Abstract

The invention relates to a bright flame type smokeless sulfur-free firecracker nitrate medicament and a preparation method thereof, and belongs to the field of environment-friendly pyrotechnic compositions. The bright flame type smokeless sulfur-free firecracker nitrate medicament is composed of the components: passivated hexogen, nitrified bamboo cellulose, titanium deuteride, calcium metasilicate, 4-nitrotriphenylamine, a calcium glycinate complex, dicyandiamide and methyl silicone oil. Passivated hexogen is used as a main component, and titanium deuteride powder is used, so that the brighteffect generated by setting off the firecracker nitrate medicament is ensured; nitrated bamboo cellulose, 4-nitrotriphenylamine and dicyandiamide are adopted, and the calcium glycinate complex and methyl silicone oil are added, so that the mechanical property and the stability of the firecracker nitrate medicament can be remarkably improved, and the safety and the reliability of the firecracker nitrate medicament in the production, storage and use processes are guaranteed; meanwhile, the product does not contain a sulfur element, does not contain any single-component metal powder, is sufficient in combustion, and can truly realize the preparation of the smokeless sulfur-free firecracker nitrate medicament.

Description

technical field [0001] The invention relates to a bright-flame smokeless and sulfur-free firecracker nitrate agent and a preparation method thereof, belonging to the field of environment-friendly pyrotechnic agents. Background technique [0002] In various festivals and celebrations in China, fireworks and firecrackers are widely used and have been popular for a long time. In recent years, due to the continuous growth of consumption, the lack of environmental protection awareness and the surge of manufacturers, the setting off of fireworks and firecrackers has caused serious environmental problems and also seriously affected human health. [0003] As we all know, the main ingredients of today's pyrotechnics are potassium nitrate, sulfur and charcoal, and some also contain potassium perchlorate, potassium chlorate, and even metal powder. Its discharge will produce carbon oxides, nitrogen oxides, sulfur dioxide and metal oxide dust, which will seriously damage the human respi...
