Description

technical field [0001] The invention relates to a coating method of 1,1'-dihydroxy-5,5'-bistetrazole dihydroxylamine salt (TKX-50), which belongs to the field of energetic materials. Background technique [0002] TKX-50 is a new type of cage-shaped high-energy explosive, a white crystalline granular tetrazole energetic ion salt, with high energy and low sensitivity. It is a new type of energetic material that has appeared in recent years and has been widely concerned in the global application field. Numerous literatures have recorded reports on the optimization of synthesis process conditions and formula theoretical calculations of TKX-50, but there are few research literatures on insensitivity and charge application. Reasonable surface coating treatment of simple explosives without affecting the explosive performance is the key to the charging technology of explosives and whether single explosives can be applied in multiple links. Since James’ high-efficiency coated explos...

AI Technical Summary

Problems solved by technology

TKX-50 is a kind of salt energetic material, which has high requirements on material compatibility, and the effect of directly coating the interface with polymer is poor, and the mechanical properties and detonation performance of the charge are not ideal; the composite material coating TKX-50 has a good prospect, and so far there is no report on the successful use of this method to coat TKX-50; when surfactants are used to coat TKX-50, factors such as the type and amount of surfactants will affect the performance of the product

[0003] Nitroguanidine (NQ) is a white needle-like crystal with extremely low mechanical sensitivity of 0%. It is an excellent passivator for energetic materials. The physical properties of its crystal surface are similar to those of TKX-50, both of which are inorganic salts It is a kind of energetic material and has good compatibility, but there is no literature report on the use of nitroguanidine and polymer materials in the coating of insensitive TKX-50 of TKX-50 explosives
