Abstract
The present invention discloses a safety powder agent, which relates to an explosive composition containing inorganic oxyhalogen acid salt. The explosive composition contains ammonium perchlorate, plant cellulose combustion agents, titanium powders, zinc powders, ferrous powders, aluminum powders or aluminum slag powders, catalysts of ferroferric oxide, copper oxide, etc., a color-developing agent, an appropriate amount of static electricity preventing agent, and an appropriate amount of an agent for rust prevention and hydrolysis resistance. The safety performance of the powder agent is superior to the safety performance of a white potassium chlorate powder agent, and the safety powder agent of the present invention does not have the sulfur taste and has small-degree environmental pollution. The safety powder agent can be used for making electric flashing firecrackers, flower adding firecrackers, fragrant firecrackers, double sound firecrackers and hand-held fireworks and can also be used as safety explosives to replace nitramine explosives.
Description
The present invention relates to a kind of composition that contains inorganic halogen polyoxometalate, 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 and sulfide itself have sulfur-containing aroma, outside the depollution environment, also give uncomfortable feeling when the burning firecracker, and therefore, these are not the ideal composition of cracker powder agent.At present, the pyrotechnics composition that useful ammoniumper chlorate is made oxygenant is the prescription described in the U.S. Patent application US3262824 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 complete performance.
Oxygenant in the agent of this cracker powder adopts ammoniumper chlorate, and 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.
