Abstract

Provided is a novel combustion agent which is stable and efficient. The stable and efficient novel combustion agent comprises the following components in parts by weight: 18-21 parts of high-energy aluminum alloy powder or magnesium-aluminum alloy powder, 12-15 parts of ferric oxide, 3-5 parts of molybdenum trioxide, 50-55 parts of copper oxide, 0.5-2 parts of tungsten powder, 1-3 parts of a free-flowing agent and 2-5 parts of fluororubber. The stable and efficient novel combustion agent is prepared by a series of steps of raw material powder mixing, granulation glue solution preparation, mixing granulation and the like. The stable and efficient novel combustion agent disclosed by the invention is easier to mix uniformly, the safety of the preparation process is improved, the fusing and melting-through action capability of flame jet on a metal target object is improved, and meanwhile, various sensitivity indexes are reduced; the compatibility is good, and the stability is excellent; the combustion temperature can reach 2800 DEG C or above, and the flame retardant can be used for igniting materials, damaging core components of facilities and equipment and melting down strip-shaped, rod-shaped and linear metal obstacles. In addition, the invention also provides a preparation method of the stable and efficient novel combustion agent.

Description

technical field [0001] The invention relates to the technical field of metal compound combustion agents, in particular to a stable and efficient novel combustion agent and a preparation method thereof. Background technique [0002] A chemical substance used for mutilation and arson purposes that produces a high temperature or fiery flame when a burning agent burns. In modern times, thermite and iron-aluminum high-heating agent are commonly used as the main energy sources. Usually, ferric oxide and ferric oxide are used as oxidants, which can decompose and release oxygen at moderate temperatures, but thermite and iron-aluminum high-heating agent A layer of slag film is often attached to the surface of the metal target after the high-temperature flame jet fuses and penetrates, which has a certain heat insulation effect on the metal target, which affects the effect of high-temperature flame fuse and penetration, and is difficult to meet the use requirements. . [0003] The co...
