Problems solved by technology

However, the propellant has not been treated with a passivation agent, and the impact sensitivity and friction sensitivity are still high. There is a risk of deflagration, and the safety is insufficient.
[0005] In China's invention patent application 201510674279.6 (publication date: February 17, 2016), a formulation and preparation method of a coated nail-shooting ammunition tablet without firing powder is disclosed. The formulation components and weight percentages are: nitrocellulose 89.80%~99.78%, stabilizer 0.20%~0.75%, binder 0.01%~0.45%, coating material 0.01%~3.0%, solvent ≤ 1.0%, moisture ≤ 5.0%; with hydrous nitrocellulose as the base material , by adding water-containing nitrocellulose, solvent, stabilizer, and binder into the gelling kneader, the gelation is completed after mi

Abstract

The invention discloses a safe and environment-friendly launched medicinal composition. The safe and environment-friendly launched medicinal composition comprises the following raw materials in partsby weight: 78-88 parts of wood pulp nitrocellulose, 5-10 parts of azidonitramine, 1-3 parts of a first desensitizing agent, 2-5 parts of a second desensitizing agent, 1-3 parts of a stabilizing agent,0.5-1.5 parts of an adhesive and 3-7 parts of a solvent. The launched medicinal composition provided by the invention has the friction sensitivity and impact sensitivity of 0, the moisture absorptionrate being lower than 1%, does not contain sulfur in components, has the thrust being 5-7 times that of the conventional black powder, is small in environment pollution and high in safety performance, has relatively good safety, stability, heat resistance, cold resistance and other properties, can meet using requirements, and has a relatively good market application prospect.

Description

technical field [0001] The invention belongs to the technical field of propellant preparation, and more specifically relates to a safe and environment-friendly propellant composition. Background technique [0002] With the development of society, propellants are widely used in daily life and celebration activities. Most of the existing propellants are black powder, whose main components are potassium nitrate, sulfur, fir powder, etc., which adopt traditional manufacturing methods. It has been used for hundreds of years. The main working principle is to ignite the black powder through the fuse to generate upward power to push the fireworks cartridge into the air. However, there are disadvantages such as easy to be affected by moisture, low safety performance, and easy to cause environmental pollution (the smog is relatively large). In addition, this type of black powder has a low ignition point (398°C), sulfur content, high friction sensitivity, impact sensitivity and moistu...
