The incendiary agent comprises, by mass, 30 to 40% of polytetrafluoroethylene, 30 to 45% of magnesium powder, 5 to 10% of a phenolic resin, 10 to 30% of a nanometer composite thermite and 3 to 8% of a slagging flux. During combustion of the incendiary agent, infrared radiation covers wavebands in ranges of 3 to 5 mu m and 8 to 14 mu m, and specific radiant energy are respectively no less than 187 J/g/Sr and 35 J/g/Sr. According to the invention, the high-energy infrared-radiation incendiary agent can generate strong infrared radiation during combustion, so thermal conduction performance of an igniting (or flame-transferring) reagent can be effectively enhanced.
Description
Technical field
The invention belongs to energetic material technical field, particularly can produce the high energy ir radiation incendiary material of high energy ir radiation output during a kind of burning.
Background technology
Magnesium/tetrafluoroethylene have containing can be high, flameholding, making is simple and safe, with low cost and have the features such as good consistency with other components, it is widely used in igniting (or passing fire) medicament of car safety air bag and rocket engine as incendiary material.According to heat transfer theory, the ir radiation producing in magnesium/tetrafluoroethylene combustion processes is the heat conducting important channel of ignition powder.Therefore, the infrared radiation property of research raising incendiary material is the research emphasis in this field.And in the situation that equipment load is certain, being subject to the restriction of volume and weight, infrared energy when emphasis need to improve the burning of incendiary material unit mass, than radiating capacity.
At present, Chinese scholars, for improving the ratio radiating capacity of magnesium/tetrafluoroethylene incendiary material, has been carried out the research of a large amount of this respects.Chen Minghua studied magnalium as combustible agent proportionings different from tetrafluoroethylene, in magnesium/tetrafluoroethylene incendiary material, add the impact on incendiary material radiance such as carbon fiber, result shows that the best than radiating capacity is: 3-5 mu m waveband 134.9Jg
