Embodiment 1
[0061] This embodiment provides a mixed explosive structure including mixed crystal particles 1, such as figure 1 As shown, the mixed crystal particle 1 is coated with a coating film 2;
[0062] The mixed crystal particles 1 include CL-20 explosive 3 and aluminum powder 4, and the CL-20 explosive 3 and aluminum powder 4 are partially bonded by a binder 5;
[0063] The coating film 2 is composed of paraffin wax, talcum powder and sodium dodecylbenzenesulfonate.
[0064] CL-20 explosives are ε-crystalline spherical particles with a maximum particle size of 800 nanometers.
[0065] The aluminum powder is a spherical particle with a maximum diameter of 600 nanometers.
[0066] The binder is EVA.
[0067] The mixed explosive structure is composed of the following raw materials in parts by weight: 95% of CL-20 explosive and aluminum powder, 1% of binder, 3.8% of paraffin, talcum powder and sodium dodecylbenzenesulfonate 0.2%.
[0068] The weight ratio of CL-20 explosive and alu...
Embodiment 2
[0084] This embodiment provides a mixed explosive structure, which is basically the same as the mixed explosive structure in Example 1, the only difference being that in this embodiment:
[0085] The mixed explosive structure consists of the following raw materials in parts by weight: 95% of CL-20 explosive and aluminum powder, 2% of binder, 2.8% of paraffin, talcum powder and sodium dodecylbenzenesulfonate 0.2%.
[0086] CL-20 explosives are ε-crystalline spherical particles with a maximum particle size of 700 nanometers.
[0087] The aluminum powder is a spherical particle with a maximum diameter of 350 nanometers.
[0088] The binder is EVA.
[0089] The weight ratio of CL-20 explosive and aluminum powder is 85:10.
[0090] The weight ratio of talcum powder and sodium dodecylbenzenesulfonate is 1:1.
[0091] The melting point of paraffin is 58°C.
[0092] The molding process of the mixed explosive structure in this embodiment is the same as that of the mixed explosive ...
Embodiment 3
[0096] This example provides a mixed explosive structure, which is basically the same as the mixed explosive structure in Example 1, the only difference being that in this example: the weight ratio of CL-20 explosive to aluminum powder is 80:15.
[0097] The molding process of the mixed explosive structure in this embodiment is the same as that of the mixed explosive structure in Example 1.
[0098] The characterization results of the mixed explosive structure in this example are basically the same as those in Example 1.
