Embodiment 1
[0034] A cast solidified insensitive high-explosive thermal explosive, the formula of which consists of: RDX: 65 parts, Al: 21.5 parts, HTPB: 7 parts, WAX: 2.85 parts, DOS: 3.11 parts, TDI: 0.54 parts.
[0035] The coarse and fine particle gradation adopted by RDX is as follows: coarse particles with a particle size ranging from 0.250 mm to 0.420 mm account for 61.5% of the mass of RDX, fine particles with a particle size of ≤0.05 mm account for 38.5% of the mass of RDX, and the particle size of the fine particles is ≤0.05 The particle content of mm is not less than 97% of the amount of fine particles; the particle size of fuel aluminum powder ranges from 0.005mm to 0.05mm.
[0036] The preparation method of the pouring solidification type insensitive high-explosive thermal explosive mainly comprises the following steps:
[0037] (1) Ingredients: Quantitatively weigh each component in the formula and set aside;
[0038] (2) Mix materials by feeding in batches and kneading: th...
Embodiment 2
[0060] A cast solidified insensitive high-explosive thermal explosive, the formula of which consists of: RDX: 65 parts, Al: 21.5 parts, HTPB: 7 parts, WAX: 2.85 parts, DOS: 3.11 parts, TDI: 0.54 parts.
[0061] The coarse and fine particle gradation adopted by RDX is as follows: coarse particles with a particle size range of 0.250 mm to 0.420 mm account for 64.6% of the mass of RDX, fine particles with a particle size of ≤0.05 mm account for 35.4% of the mass of RDX, and the particle size of the fine particles is ≤0.05 The particle content of mm is not less than 97% of the amount of fine particles; the particle size of fuel aluminum powder ranges from 0.005mm to 0.05mm.
[0062] The preparation method and the vacuum pouring device used are the same as in Example 1.
Embodiment 3
