Abstract

The invention discloses a compound pyrotechnic high-energy combustion agent which comprises the following components in percentage by mass: 35-40 percent of polytetrafluoroethylene, 35-40 percent of magnesium powder, 3-6 percent of a phenolic resin adhesive, 10-16 percent of nano-composite thermite, 1-5 percent of an alloying agent and 3-8 percent of a slag former. The compound pyrotechnic high-energy combustion agent is easy to ignite, high in combustion temperature, long in combustion time, large in flame area and high in applicability.

Description

technical field [0001] The invention belongs to the technical field of energetic materials, in particular to a composite pyrotechnic high-energy combustion agent with high energy output. Background technique [0002] Pyrotechnic combustion agent is composed of combustible agent and oxide. Due to its controllable composition design, high energy content, safe and convenient preparation and low cost, it is widely used in various fields as an important chemical combustion energy, mainly used for ignition, arson and Infrared combustion radiation materials, etc. The energy output is generated by combustion, so as to realize the preset function. Therefore, the combustion agent requires a high combustion temperature during combustion, a long duration of combustion, and a large flame area during combustion. [0003] At present, the commonly used pyrotechnic combustion agent is mainly composed of magnesium / polytetrafluoroethylene, magnesium powder is the combustible agent, polytetra...
