Embodiment 1

[0027] Step 1: Preparation of laser direct detonation agent powder

[0028] Take 1.0g of the prepared silver-based cationic energetic metal-organic framework [Ag(ATCA)ClO 4 ] n Mixed with 50mg of molybdenum disulfide, and ground into 100um powder material;

[0029] Step 2: Charging and packaging of laser direct detonation agent powder

[0030] The prepared laser direct detonation powder is divided into two times and pressed into the detonator. The lower 500mg powder is pressed into the detonator with a pressure of 30MP, and the pressure is kept for 5min before unloading; after the upper layer of 500mg is loaded, the pressure is released immediately after the pressure of 1MP. Press and seal the detonator with window glass.

[0031] Step 3: Laser initiation performance test based on femtosecond laser

[0032] A femtosecond laser with a wavelength of 800 nm was used to test the detonation performance of the laser detonator prepared by the above method. When the frequency of ...

[0034] Step 1: Preparation of laser direct detonation agent powder

[0035] Take 1.0g of the prepared silver-based cationic energetic metal-organic framework [Ag(ATCA)ClO 4 ] n Mixed with 30mg of molybdenum disulfide, and ground into a 50um powder material;

[0036] Step 2: Charging and packaging of laser direct detonation agent powder

[0037] The prepared laser direct detonation powder is divided into two times and pressed into the detonator. The lower layer of 500mg powder is pressed into the detonator at a pressure of 20MP, and the pressure is kept for 5 minutes before the pressure is unloaded; after the upper layer of medicament is loaded with 500mg, the pressure is released immediately after the pressure of 5MP. Press and seal the detonator with window glass.

[0041] Step 1: Preparation of laser direct detonation agent powder

[0042] Take 1.0g of the prepared silver-based cationic energetic metal-organic framework [Ag(ATCA)ClO 4 ] n Mixed with 20mg of molybdenum disulfide, and ground into a 300um powder material;

[0043] Step 2: Charging and packaging of laser direct detonation agent powder

[0044] Press the prepared laser direct detonation powder twice into the detonator. The lower layer of 500mg powder is pressed into the detonator with a pressure of 35MP, and the pressure is kept for 5min before unloading; after loading the upper layer of 500mg of medicament, it is released immediately after the pressure of 2MP. Press and seal the detonator with window glass.

[0045] Step 3: Laser initiation performance test based on femtosecond laser

[0046]A femtosecond laser with a wavelength of 800 nm was used to test the detonation performance of the laser detonator prepared by the above method. When the frequency of the femtosecon...

Abstract

The application of a silver-based cationic energetic metal-organic framework as a laser direct priming agent formulation, using the chemical formula [Ag(ATCA)ClO 4 ] n The energetic metal-organic framework material is used as its core material, where ATCA is the neutral ligand of 3-amino-1H-1,2,4-triazole-5-carbohydrazide, and a small amount of molybdenum disulfide is added as Adjuvant. Through the application of the silver-based cationic energetic metal-organic framework of the present invention as the formulation of the direct laser priming agent, it is a new type of lead-free green laser priming agent formulation, which is more green and environment-friendly. At the same time, the formula has a higher ignition response to the femtosecond laser, and its ignition time and ignition energy are lower, which is better than using priming agents such as lead azide first. The preparation method of the invention has simple technological process, convenient operation, mild reaction conditions, good safety and high product quality.

Description

technical field [0001] The invention relates to the technical field of novel energetic materials, and more specifically relates to the application of a silver-based cationic energetic metal-organic framework as a laser direct priming agent formula. Background technique [0002] At present, the primary explosives used in my country mainly include lead azide, metal salts of picric acid and styphonic acid, etc., but most of these primary explosives are extremely sensitive to external stimuli, often causing accidental explosions, resulting in heavy losses of personnel and property. Therefore, it is necessary to urgently seek a safer new type of detonating agent in production and use, which should have characteristic sensitivity, can be reliably ignited or detonated by flame, electric heating wire, laser, and will not be affected by external sudden stimulation (static electricity). , impact, friction, etc.) are more blunt. [0003] At present, researchers in this field around th...
