Description
The present invention relates to a kind of blasting explosives composition that contains inorganic halogen polyoxometalate.It is a kind of cracker powder agent that contains ammoniumper chlorate.
Great majority contain Potcrate, sulphur or sulfide in the existing cracker powder prescription.Owing to the Potcrate poor chemical stability, be easy to catch fire, therefore, produce, storing and use in be absolutely unsafe.And sulphur or sulfide itself have sulfur-containing aroma, outside the depollution environment, also give uncomfortable feeling when setting off firecracker, and therefore, these are not cracker powder agent ideal compositions.At present, useful ammoniumper chlorate is made the pyrotechnics composition of oxygenant, the prescription described in the U.S. Patent application US3.262824 for example, and it contains 74.2% ammoniumper chlorate, 11.1% stearic acid, 3.6% paraffin, 11.1% copper powder.But this prescription should not be done the cracker powder agent.
The objective of the invention is to study a kind of firework display effect and be equivalent to the agent of Potcrate baiyao, and item safety performances such as impact sensitivity, friction sensitivity, heat sensitivity, flame sensitivity and electrostatic sensitivity all are better than the safety powder composition of Potcrate baiyao agent.Another purpose is to reduce the firecracker production process, reduces when setting off the pollution to environment.Another purpose provides a kind of safety explosive that all is better than ammonal in humidity resistance, explosive power and safety performance.
Oxygenant in the agent of this cracker powder adopts ammoniumper chlorate.Incendiary material adopts plant cellulose, as weedtree, pine, Sha Mu, China fir, low density staple fibre residue and charcoal, starch.For firecracker and the fireworks that obtain various kinds, can add various metal-powders such as aluminium powder (or aluminium ground-slag), iron powder, zinc powder, titanium valve and developer Strontium carbonate powder, copper carbonate, nitrate of baryta or cupric oxide etc. as required, different glory when obtaining setting off.In addition, also added catalyzer, as Z 250, copper chromite, ferric oxide, cupric oxide.For improving performance, antistatic agent and antirust hydrolysis-resisting agent that other components in an amount of and the prescription do not have chemical reaction have also been added.

Z 250 5%(weight)
The antistatic agent trace
Powder composition preparation method: accurately weigh by formula rate, respectively oxygenant, incendiary material, catalyst powder are broken to more than 120 orders, mix with metal powder then, promptly make powder composition.
The powder composition that makes is joined in the firecracker paper web, make firecracker after solid flashing composition seals through inserting to draw and add.Contrast samples together with Potcrate baiyao agent 1#, 2# and the military black powder of 4# etc. then, carry out various performance measurements, it the results are shown in following each form
One, heat sensitivity test: the fiery explosive five seconds lag phase spontaneous ignition temperature measuring method mensuration AQ that formulates with Ministry of ordnance Industry is that gunpowder recipe and the flare point that contrasts the sample prescription see Table 1.
Table 1
Two, impact sensitivity test: press the sixth stochastic method with vertical drop impact instrument and measure, the results are shown in Table 2.
Table 2
Three, flame sensitivity: measure with Ministry of ordnance Industry's fire explosive flame sensitivity safety fuse method, the results are shown in Table 3.
Table 3
Four, static sparking sensitivity:, press Ministry of ordnance Industry's fire explosive static sparking sensitometry method under following condition with JGY-50 static sparking sensibility instrument
C=9360.1PF R string=85K Ω
Powder volume is 20mg, and needle point is a negative polarity, and needle point is 1mm from the gap of gunpowder, records and the results are shown in Table 4.
Table 4
Five, shelf test:
1. wettability test: measure the method for hydroscopicity by MILSTD MIL-STD-1234, measure the weightening finish of 5g medicament after reaching balance with ambient moisture under 30 ℃ of temperature and see Table 5.
Table 5
After the test, the sample making firecracker that moisture absorption is saturated, it is constant that it sets off effects,sound.
2. thermocycling: with powder composition is that 70 ℃ of humidity are 70% and after temperature deposits 24 hours under for-30 ℃ of conditions in temperature respectively, takes out, and measures its firework display effect, and each index all meets the SG237-81 of Ministry of Light Industry ministerial standard.
To place under-30 ℃ conditions low-temperature test on the above-mentioned experimental basis respectively through the sample of 70 ℃ of high temperature test 24 hours, to place 24 hours down for 70 ℃ at high temperature again through-30 ℃ of samples of testing down, measure its firework display effect at last, all meet the SG237-81 of Ministry of Light Industry standard.As seen, prescription thermostability of the present invention is fine.
3. shelf test: make firecracker, the equal conformance with standard requirement of its performance powder composition prescription of the present invention deposited 8 months in humidity is 90% moisture eliminator after.
Six, set off sound level test:
Be positioned over apart from five meters distant places, firecracker ignition point with a precision sound level meter of forming by a CH16 type capacitor microphone and FDC-2A type microphone amplifier, measure the loudness when setting off, the results are shown in Table 6.
Table 6
| The sample title | The sound intensity when setting off (db) SL (B) |
| AQ-1 | 105 |
| AQ-2 | 111 |
Annotate: the control sample composition of above test is as follows:
Baiyao agent 1# contains:
KclO
355%(weight), sulphur 12%,
Al powder 15%(weight), charcoal 18%,
Baiyao agent 2# contains: (weight %)
KclO
353%, sulphur 15%,
Al powder 14%, charcoal 18%,
More than test confirms, powder composition of the present invention has good safety performance and sets off performance.Therefore, in production, storing and use, significantly reduced explosion hazard.On the other hand, owing to no sulphur and sulfide in the prescription, avoided the sulfur dioxide pollution environment and produced stink.Moreover, be controlled in basic nitrogenfree oxide (NO owing to fire temperature of reaction
x) under the condition that produces, so NO
xConcentration and chlorine hydride gas concentration five meters with the external space all within safe level.Powder composition of the present invention seals firecracker as being equipped with certain solid flashing composition, then can significantly reduce the production process of firecracker, and cost is reduced.More than prescription can be respectively applied for to produce and add firework, electric light big gun, fragrant big gun and double-bang firecracker and hand-held fireworks.Also can be used as safety explosive, replace ammonal, its humidity resistance, safety performance and bursting force all are better than ammonal.
