Problems solved by technology

Although these primary explosives are simple to synthesize and cheap in price, there is a relatively serious lead pollution problem in their explosive products, and due to insufficient explosive performance, a large amount of metering is required when detonating.
Therefore, new primary explosives do not contain lead and have stronger explosive performance, such as dinitroammonium bistetrazolium potassium salt, but its synthesis steps are numerous, there is a large risk and the price is expensive, which is not conducive to commercial application

Embodiment 1

[0052] The preparation of embodiment 1 sample

[0053] Mix the raw materials of metal salt, 4,4′-azo-1,2,4-triazole and sodium azide evenly, put them into the reactor, add a certain amount of water as solvent, 40~ heating and stirring at 100°C for 0.1 to 5 hours, and filtering to obtain the energetic material MC 4 h 4 N 14 . The sample numbers, types and amounts of raw materials, heating temperature, stirring time and crystals are shown in Table 1.

Embodiment 2

[0056] The structural characterization of embodiment 2 sample

[0057] Sample P1 # ~P7 # X-ray powder diffraction phase analysis (XRD) after grinding was carried out on MiniFlex600 X-ray diffractometer of Rigaku Company, Cu target, Kα radiation source (λ=0.154184nm). The results showed that the prepared samples were all samples with high purity and high crystallinity.

[0058] Sample P1 # ~P7 # The X-ray single crystal diffraction was carried out on a Mercury CCD type single crystal diffractometer, Mo target, Kα radiation source (λ=0.07107nm), test temperature 293K. And analyze the structure through SHELXTL-2013. Take P1 # As a typical representative, the XRD diffraction pattern obtained by fitting the single crystal data is compared with the experimentally measured XRD diffraction pattern as follows: figure 1 As shown, it can be seen that the XRD diffraction pattern obtained by fitting single crystal data is highly consistent with the experimentally measured XRD diffra...

Embodiment 3

[0063] Example 3 Friction Sensitivity Experiment and Electrostatic Spark Sensitivity Experiment

[0064] For sample P1 # ~P7 # Carry out the friction sensitivity experiment, the specific steps are as follows:

[0065] According to the national military standard test standard for energetic materials, we use the BAM friction sensitivity tester FSKM-10 produced by the Czech OZM company to determine the value corresponding to the 50% ignition rate of the compound through dozens of tests.

[0066] Take P7 # For example, the explosion diagram of the friction sensitivity experiment is as follows image 3 shown. Depend on image 3 It can be seen that the sample exploded violently during the test.

[0067] For sample P1 # ~P7 # Conduct electrostatic spark sensitivity experiment, the specific steps are as follows:

[0068] According to the electrostatic spark sensitivity test standard of energetic materials, we use the electrostatic spark sensitivity tester Xspark8 produced by ...

Description

technical field [0001] The application relates to an energetic material, its preparation method and its application as a primer, explosive and pyrotechnic agent, belonging to the field of energetic materials. Background technique [0002] Energetic materials are mainly used in fields such as primers, explosives and pyrotechnic agents. The current commercial primary explosives mainly include lead azide Pb(N 3 ) 2 (LA), lead stephnate C 6 h 3 N 3 o 9 Pb(LS) etc. Although these primary explosives are simple to synthesize and cheap in price, there is a relatively serious lead pollution problem in their explosive products, and a large amount of measurement is required when detonating due to insufficient explosive performance. Therefore, the new primary explosives do not contain lead and have stronger explosive performance, such as dinitroammonium bistetrazolium potassium salt, but its synthesis steps are numerous, there is great danger and high price, which is not conduciv...
