Embodiment 1
[0016] The present invention is carried out with reference to the following mass percentage composition: 50% of 3,4-dinitrofurazanylfuroxan, 44% of dihydroxyammonium 5,5-bistetrazolium-1,1-dioxide, 5% of aluminum powder %, 80# microcrystalline wax 1%.
[0017] Preparation method: Melt 500g of 3,4-dinitrofurazanylfuroxan and 10g of microcrystalline wax in a jacketed steam melting pot, add 440g of 5,5-bistetrazole-1,1-di Dihydroxyammonium oxide and 50g of aluminum powder are mixed evenly and then poured into a heat-resistant polyethylene plastic bag. After solidification, knead into powder and sieve to obtain a sample of the drug powder. Pour the powder into the mold to heat and melt, and after natural cooling, the grain sample can be obtained.
Embodiment 2
[0019] The present invention is carried out with reference to the following mass percentage composition: 3,4-dinitrofurazanylfuroxan 56%, 5,5-bistetrazolium-1,1-dihydroxyammonium dioxide 38%, aluminum powder 5 %, 80# microcrystalline wax 1%.
[0020] The manufacturing method of this embodiment is carried out with reference to Example 1.
Embodiment 3
[0022] The present invention is carried out with reference to the following mass percentage composition: 45% of 3,4-dinitrofurazanylfuroxan, 43% of dihydroxyammonium 5,5-bistetrazolium-1,1-dioxide, 10% of aluminum powder %, 80# microcrystalline wax 2%.
[0023] The manufacturing method of this embodiment is carried out with reference to Example 1.
[0024] Table 1
[0025]
[0026] Compared with the comparative example, the present invention has a greater increase in detonation velocity and Gurney coefficient when the charge density is equivalent, wherein the detonation velocity is increased by 2.99% at most, the Gurney coefficient is increased by 7.43% at most, and the mechanical sensitivity is equivalent to that of the comparative example.
