Abstract

The invention provides combustible glue used for destroying unexploded ordnance and a preparation method and application thereof. The combustible glue is prepared through the following steps that Al powder and Fe3O4 powder are evenly mixed to obtain Al / Fe3O4 mixed powder; lac is dissolved in absolute ethyl alcohol to obtain a lac absolute ethyl alcohol solution with the mass concentration being 5%-6%; the Al / Fe3O4 mixed powder is added into the lac absolute ethyl alcohol solution, and the Al / Fe3O4 mixed powder and the absolute ethyl alcohol solution are stirred to be evenly mixed; glass fiber powder is added and stirred to be evenly mixed; and expandable graphite is added and stirred to be evenly mixed to obtain the combustible glue. The mass ratio of the Al powder to the Fe3O4 powder is 7-8 to 15. The massic volume ratio of the Al / Fe3O4 mixed powder to the lac absolute ethyl alcohol solution is 1g to 2-3 mL. The adding amount of the glass fiber powder is 1%-3% of the Al / Fe3O4 mixed powder by mass. The adding amount of the expandable graphite is 1%-3% of the Al / Fe3O4 mixed powder by mass. The combustible glue is low in combustion speed, large in combustion heat output and long in combustion duration, and can heat explosives in the unexploded ordnance once being ignited, and it can be ensured that the explosives in the unexploded ordnance are reliably detonated.

Description

technical field [0001] The invention relates to a combustible glue and its preparation method and application, in particular to a combustible glue for destroying unexploded ammunition and its preparation method and application. Background technique [0002] Unexploded ordnance is a problem often encountered in military operations, training, and experiments. The appearance of unexploded ordnance seriously threatens the safety of surrounding personnel, facilities and equipment, and interferes with the normal development of military operations and military training. Measures need to be taken to eliminate it as soon as possible. The existing method of destroying unexploded ordnance is mainly to detonate and destroy. Explosion needs to be bundled in advance, and the detonator is detected. It is necessary for the detonator to touch the unexploded ordnance and place the detonation explosive. The work is cumbersome and dangerous, labor-intensive and low in efficiency. . In addition...
