Description

Technical Field

[0001] This invention belongs to the field of energetic material modification technology. More specifically, this invention relates to a method for preparing spherical TATB-based explosives based on TNT as a binder. Background Technology

[0002] 1,3,5-Triamino-2,4,6-Trinitrobenzene (TATB) is an extremely important elemental high-energy insensitive explosive, favored for its excellent thermal stability, low mechanical sensitivity, and significant safety performance. This explosive has been widely used in weapon systems, ammunition propellants, and related military fields where safety requirements are extremely high. However, TATB crystals themselves have some significant drawbacks, such as high hardness, irregular morphology, and a wide particle size distribution. These problems result in relatively poor processing performance of TATB in the preparation of composite explosives, making it difficult to directly meet the specific requirements of actual production processes. To effectively improve the formability and mechanical properties of TATB, polymer binders are usually introduced. Through various modification methods such as coating and bonding, TATB-based polymer-bonded explosives (PBX) are comprehensively modified, thereby significantly improving their overall performance and enhancing their feasibility and reliability in practical applications.

[0003] He et al. used CNTs and GNPs as thermally conductive fillers and employed ultrasonic dispersion and hot pressing techniques to enhance the thermal conductivity of TATB-based PBX composites, obtaining PBXs with significantly improved thermal conductivity (up to 1.41 W·m). -1 ·K -1 Experiments revealed that the ratio and dispersion state of GNPs to CNTs significantly affect the thermal conductivity and mechanical properties of PBXs. Furthermore, the synergistic effect of the hybrid filler can form a three-dimensional thermally conductive network, effectively reducing interfacial thermal resistance. Using hybrid CNT / GNP fillers can significantly improve the thermal conductivity and thermal shock resistance of PBXs at low addition levels (1.31 vol%). However, the dispersibility of the filler in the polymer and the control of interfacial thermal resistance remain key challenges. The presence of highly filled exploding crystals further complicates the construction of the thermally conductive network, and the application of this technology in practical PBX engineering still faces significant obstacles. (PolymerComposites, 2018, 39(S3): E1452-E1462.) Zhou Jinqiang et al. used droplet microfluidics, with ethyl acetate as solvent and F2602 as binder, to prepare TATB-based PBX composite microspheres, achieving precise control over the morphology and particle size of the microspheres. D 50The particle size ranged from 44.31 to 51.73 μm. Experiments revealed that the binder content and the two-phase flow ratio significantly affected the sphericity, surface smoothness, and particle size distribution of the microspheres. Furthermore, microspheres with high sphericity (0.921) and good monodispersity (span <0.4) were obtained when the F2602 content was 5% and the flow ratio was between 12.5 and 15. The use of droplet microfluidics effectively improved the coating uniformity and thermal stability of TATB particles, delaying the thermal decomposition peak by 4.08℃ and increasing the true density of the material to 1.9780 g·cm³. -3 However, this technology still faces challenges in large-scale practical applications, such as optimizing process parameters, scaling up equipment, and achieving continuous production. (Energetic Materials, 2022, 30(05):439-445.) Zhou et al. functionalized molecules with dopamine (POPA) and 2-ureido-4[1H]-pyrimidinone (UPy) and used surface coating and chemical grafting methods to modify the interface of TATB crystals to enhance the mechanical properties of TATB-based polymer-bonded explosives (PBX). Experiments showed that first increasing surface roughness and reaction sites through polydopamine (PDA) coating, followed by grafting of UPy derivatives containing –NCO groups, significantly enhanced the interfacial hydrogen bonding between TATB and the fluoropolymer binder. When the UPy grafting amount was 1 wt%, the tensile strength and compressive strength of PBX increased by 35.6% and 26.5%, respectively, and the creep resistance was also significantly improved. Theoretical simulations indicated that strong hydrogen bonding and van der Waals interactions exist between UPy and TATB at the interface, which are the main mechanisms for performance improvement. This surface grafting method is mild and widely applicable, and can be used for interfacial reinforcement of other composite energetic materials. However, the optimal content and distribution of UPy, long-term aging performance, and the feasibility of large-scale production processes still require further investigation. (EnergeticMaterials Frontiers,2024,5(2):121-130.) While these literature reports have successfully improved the performance of TATB-based explosives or achieved effective modification of other explosives using TATB, the technologies involved still have many shortcomings and have not yet met the actual needs of industrial production. Therefore, designing and inventing a method to effectively improve the performance of TATB-based explosives and make them meet the needs of industrial production is an urgent problem to be solved in this field. Summary of the Invention

[0005] To achieve these objectives and other advantages of the present invention, a method for preparing spherical TATB-based explosives using TNT as a binder is provided, comprising the following steps: Step 1: Add surfactant to water, heat and stir to obtain an aqueous dispersion; Step 2: Heat the adhesive in a water bath until it melts, add TATB and stir until it is mixed evenly to obtain a mixture. Then add the mixture to the aqueous dispersion, continue heating and stirring until it is stable, then stop heating and cool it to room temperature through a programmed cooling process. Step 3: Filter, wash, and dry to obtain spherical TATB-based explosives.

[0006] Preferably, in step one, the water is pure water, and the mass-to-volume ratio of water to surfactant is 100~300mL:0.01~0.1g.

[0007] Preferably, in step one, the surfactant is one or more of gum arabic, shellac, polyvinylpyrrolidone, sodium dodecylbenzene sulfonate, hexadecylpyridine, sodium dodecyl sulfate, sodium hexadecyl sulfate, sodium octadecyl sulfate, sodium dioctane succinate sulfonate, polyvinyl alcohol, polyethylene glycol, dichloromethane, Span 20-80, and Tween 20-80; the mass of the surfactant is 0.01% to 5% of the mass of TATB.

[0008] Preferably, in step one, the polyethylene glycol is modified by means of: S1. Dissolve 1-5 parts polyethylene glycol and 0.3-0.6 parts chlorogenic acid in 40-60 parts N,N-dimethylformamide by weight, and stir until completely dissolved to obtain a mixture. S2. Add 0.4~0.6 parts of N,N'-diisopropylcarbodiimide to the mixture and react for 6~18 hours under nitrogen atmosphere and room temperature to obtain the reaction solution; S3. Filter the reaction solution, dialyze the filtrate with deionized water for 12-48 hours, dry it with anhydrous calcium sulfate, filter it again, and concentrate the filtrate to obtain modified polyethylene glycol.

[0009] Preferably, in step one, the temperature is raised to 20~100℃ and the stirring rate is 100~1000 r / min.

[0010] Preferably, in step two, the adhesive is TNT, and the mass ratio of the adhesive to TATB is 1:1 to 1:10.

[0011] Preferably, in step two, the water bath heating temperature is 70~90℃; and the stirring rate of TATB is 100~1000 r / min.

[0012] Preferably, in step two, the heating temperature for heating and stirring is 70~90℃, and the stirring rate is 100~1000r / min.

[0013] Preferably, in step two, the rate of programmed cooling is 0.1~2℃ / min.

[0014] Preferably, in step three, the washing process uses one or more of distilled water, ethanol, dimethyl sulfoxide, and ethyl acetate; and the drying method is one of room temperature drying, vacuum drying, and freeze drying.

[0015] Preferably, in step three, the particle size of the spherical TATB-based explosive is 200~1500μm.

[0016] The present invention has at least the following beneficial effects: This invention can simultaneously control the morphology and size of TATB-based explosives. Compared with other methods, the binder selected in this invention is an energetic material, which does not reduce the energy of the sample. The number of samples prepared can reach the kilogram level. In addition, the solvent used in this invention is pure water, which will not cause environmental pollution and is inexpensive.

[0017] This invention prepares uniformly sized spherical TATB-based explosives with a particle size of approximately 200-1500 μm. The crystal form and structure of the prepared samples remain unchanged, while the thermal decomposition performance is improved. This sample significantly enhances the mechanical properties of TATB.

[0018] This invention also provides a method for modifying polyethylene glycol (PEG). The method involves esterification of PEG terminal hydroxyl groups with carboxyl groups in chlorogenic acid under the catalysis of a condensing agent. Chlorogenic acid containing multiple hydroxyl groups and aromatic ring structures is grafted onto the PEG chain ends, resulting in modified PEG containing hydroxyl groups, carbonyl groups, and ether bonds. The modified PEG containing hydroxyl groups, carbonyl groups, and ether bonds can form strong interactions with the surfaces of TNT and TATB particles through multiple interaction sites, significantly improving interfacial adsorption strength and dispersion stability. The ether bonds in the molecule impart good flexibility and solubility, facilitating uniform spreading in the system. The hydroxyl and carbonyl groups can form hydrogen bonds with explosive crystals, reducing agglomeration and resulting in spherical TATB-based explosives with high sphericity, good sphericity, and uniform particle size distribution.

[0033] Figure 1 Scanning electron microscope (SEM) images of TATB raw materials and spherical TATB-based explosives prepared in Example 1. Figure 1 It is known that the raw material TATB has an irregular crystal shape, a wide particle size distribution range, high surface roughness, and an irregular layered structure; the spherical TATB-based explosive prepared in Example 1 has a particle size of 400~800 μm, a morphology of perfect sphere, and a relatively smooth surface.

Figure 2It can be seen that the characteristic diffraction peak positions of the spherical TATB-based explosive prepared in Example 1 are all located at 11.3°, 19.6°, 28.0°, and 42.4°, while the characteristic diffraction peak positions of the TNT raw material are located at 12.5°, 15.8°, 17.7°, 22.8°, and 29.2°. The characteristic diffraction peak positions of the spherical TATB-based explosive prepared in Example 1 are basically consistent with those of the two raw materials, indicating that the prepared spherical TATB-based explosive did not change the crystal form of the raw material.
