Abstract

The invention relates to an antistatic smokeless sulfur-free firecracker nitrate agent and a preparation method thereof, belonging to the field of environment-friendly pyrotechnic compositions. The firecracker nitrate agent comprises, desensitized hexogen, nitrified bamboo cellulose, modified ammonium dinitramide, magnesium stearate, 1,3-dimethyl-1,3-diphenyl urea, dicyandiamide, amino silicon oiland an antistatic agent. According to the invention, desensitized hexogen is used as a main component, and modified ammonium dinitramide is used as an oxidant, so an oxygen content is sufficient, andcombustion effect is ensured; the nitrified bamboo cellulose, 1,3-dimethyl-1,3-diphenyl urea, magnesium stearate and dicyandiamide are adopted, and the antistatic agent and amino silicone oil are added, so the mechanical properties, stability and antistatic capacity of the firecracker nitrate agent can be remarkably improved, and the safety and reliability of the firecracker nitrate agent in theprocesses of production, storage and use are guaranteed; meanwhile, the firecracker nitrate agent does not contain a sulfur element or any metal powder, so the preparation of the smokeless sulfur-freefirecracker nitrate agent can be truly realized.

Description

technical field [0001] The invention relates to an antistatic smokeless and sulfur-free firecracker nitrate agent and a preparation method thereof, belonging to the field of environment-friendly pyrotechnic agents. Background technique [0002] Fireworks and firecrackers have been widely used in Chinese festivals and have been popular for a long time, and the setting off of firecrackers has a history of nearly 1,000 years. In recent years, due to the continuous growth of consumption, the lack of environmental protection awareness and the surge of manufacturers, the discharge of fireworks and firecrackers has caused serious environmental pollution and serious harm to human health. [0003] The main ingredients of today's pyrotechnics are potassium nitrate, sulfur and charcoal, some also contain potassium chlorate, and even metal powder is added. Although carbon powder and metal powder can improve the antistatic ability of pyrotechnics, the discharge of finished fireworks and...
