Abstract

The invention discloses an ammonium nitrate fuel oil explosive prepared from HMX byproduct acidified ammonium nitrate, which comprises the following components in percentage by mass: 92-96% of acidified ammonium nitrate, 4-8% of fuel oil and an alkaline surfactant accounting for 0.2-0.5 wt% of the ammonium nitrate fuel oil explosive. The high-performance powdery ammonium nitrate fuel oil explosive is prepared by taking the byproduct acidified ammonium nitrate of the energetic material HMX production line as the oxidizing agent, the preferable fuel oil as the combustible agent and the alkaline surfactant as the neutralizing stabilizer, so that the byproduct acidified ammonium nitrate of the energetic material is subjected to resource utilization, waste is turned into wealth, and compared with a porous particle-loaded ammonium nitrate fuel oil explosive of a standard, the explosive sensitivity, the explosive performance and the storage life of the explosive are obviously improved.

Description

technical field [0001] The invention relates to the technical field of ammonium oil explosives, in particular to an ammonium oil explosive prepared by acidifying ammonium nitrate as a by-product of HMX and a method thereof. Background technique [0002] Octojin (HMX) is one of the most important basic energetic materials in the defense industry. At present, the industrial production of HMX uses the acetic anhydride method (Bachmann method), that is, acetic anhydride and nitric acid are used as nitration agents, and with the participation of ammonium nitrate , Nitrolysis of urotropine, a method for the preparation of HMX by the Buckman reaction. The main reaction equation is: [0003] The main function of ammonium nitrate in the cyclization is: when the methylol group is removed, it can inhibit and reduce the esterification, make it convert to the direction of generating cyclic nitramine, and effectively increase the yield of HMX. At the same time, change the acidity of t...
