Problems solved by technology

Therefore, although the use of water suspension method can ensure the safety of the preparation of NTO-based mixed explosive molding powder and obtain high-quality molding powder particles, a large amount of NTO is lost in the preparation process, which seriously reduces the production of NTO-based mixed explosive molding powder. rate, increasing its preparation cost
In addition, the high concentration of NTO in wastewater is difficult to degrade naturally, which will have toxic effects on animals and plants in the environment and cause great harm to the ecological environment.

Abstract

The invention relates to an NTO dissociation inhibitor and application thereof, belonging to the field of energetic materials. The invention aims to solve the problems of low yield and large pollution in the existing method. The present invention firstly prepares the NTO dissociation inhibitor by using citric acid, malic acid, glycolic acid, tartaric acid, succinic acid, ethanol and propionic acid as raw materials, then mixes the deionized water and the NTO dissociation inhibitor evenly, and then adds NTO. After heating up, the binder system is added dropwise, and the NTO-based mixed explosive molding powder is obtained after stirring, dissolving, cooling and filtering. The waste liquid can be added to the water suspension for recycling. The NTO-based mixed explosive molding powder prepared by the invention is dense and smooth, has a stable crystal form, and has little difference in mechanical sensitivity from the molding powder obtained by the prior method. Compared with the existing method, the invention can greatly increase the yield of NTO-based mixed explosive molding powder prepared by the water suspension method, and can reduce the content of NTO in the waste liquid and reduce the pollution to the environment. At the same time, the invention has simple process, mild experimental conditions, low production cost and easy realization of large-scale production.

Description

technical field [0001] The invention relates to an NTO dissociation inhibitor and its application, in particular to an NTO dissociation inhibitor and its application in the process of preparing NTO-based mixed explosive molding powder by a water suspension method, and belongs to the field of energetic materials. Background technique [0002] 3-nitro-1,2,4-triazol-5-one (NTO) is a high-energy insensitive elemental explosive, its energy level is comparable to RDX, and its theoretical detonation velocity and detonation pressure are 8550m / s and 34.9GPa, respectively; Its safety level is equivalent to that of TATB, commonly known as "wood explosives", with lower mechanical sensitivity, thermal sensitivity and shock wave sensitivity. In addition, NTO also has the characteristics of simple synthesis process and low manufacturing cost. Based on the above advantages, NTO has become one of the most promising elemental explosives at this stage, and has attracted widespread attention f...
