Starting mix of solid oxygen generator
Technical field
The present invention relates to a kind of starting mix of solid oxygen generator, belong to fiery explosive technical field, quick igniting system oxygen powder column produced oxygen when it mainly was applicable to solid oxygen generator percussion igniting.
Background technology
In background technology, starting mix in the present domestic solid oxygen generator generally all is to be main raw material with the magnesium powder, oxygenant adopts nitrate of baryta and barium peroxide, owing to limited by its composition, cause it to have the unsettled major defect of ignition characteristic, nitrate of baryta as oxygenant exists the easy moisture absorption rotten simultaneously, and there is problems such as easily decomposing instability in barium peroxide, can not satisfy the requirement of product standing storage.For overcoming these defectives, starting mix of solid oxygen generator is developed.
Summary of the invention
Technical problem to be solved by this invention provides a kind of starting mix of solid oxygen generator, it substitutes the magnesium powder with zirconium powder, makes oxygenant with alternative nitrate of baryta of ferric oxide and barium peroxide, and it can effectively improve the static sparking sensitivity, ignition characteristic and security are good, can satisfy the requirement of standing storage.
The technical scheme that the present invention solves its technical problem employing is that it is by following composition
Ferric oxide 40~70
Zirconium powder 5~25
Zircoium hydride 10~30
Diatomite 1~15
Shellac varnish 1~10
Weight percent form.
The present invention compares the beneficial effect that is produced with prior art
1, because with the alternative magnesium powder of zirconium powder, the zircoium hydride that contains in the zirconium powder can reduce the mechanical sensitivity of starting mix, the flare point of raising zirconium powder is beneficial to burning and difficult the generation exploded, and security is good.
2,,, can satisfy the long storage of product requirement so starting mix of solid oxygen generator of the present invention has moisture proof, waterproof, anti-oxidation characteristics because of ferric oxide stable in properties as oxygenant.
3, because the mechanical sensitivity of starting mix of solid oxygen generator of the present invention is lower, the static flame sensitivity is reduced, ignition characteristic is good.
