Description
Technical field
The present invention relates to the fireworks and firecrackers field, relate in particular to little cigarette propelling charge of safety that a kind of firework launching uses, environmental protection, vesicular structure.
Background technology
Present firework launching medicine is seted off a large amount of smog of rear generation, had a strong impact on the firework display effect of fireworks, and the smog main source is to have used black powder class propelling charge.In order to solve the smog problem that produces in the firework display process, worked out in the fireworks industry and adopted retired fire powder as propelling charge, compare with black powder, smog has reduced a lot, and emissivity is large, but under existing impulse charge condition, this propelling charge is poor to the ignition capability of effect medicine, leave residual medicine after causing igniting in the weapon barrel, cause the firework display effect of fireworks to be subject to having a strong impact on.
Summary of the invention
The object of the present invention is to provide a kind of fireworks with little cigarette propelling charge, only have the smog of pettiness after its burning, be easy to ignite and can guarantee the consistence of ignition quality, stability and the launching effect of fireworks.
To achieve these goals, the invention provides following technical scheme.Little cigarette propelling charge of fireworks safety, environmental protection, vesicular structure, it is characterized in that: the ratio of weight and number of described little each component of cigarette propelling charge is: 30-50 part high energy oxidizer, 1-5 part catalyzer, the single original washing powder of 10-80 part, 1-5 part tranquilizer, 1-5 part tackiness agent, 10-30 part priming explosive, 10-20 part pore whipping agent, 1-5 part are fired fast modifying agent.
Described high energy oxidizer is perchloric acid nitryl (a kind of high-energy solid propellant, molecular formula NO
3ClO
4), in the ammoniumper chlorate, potassium permanganate any one.Added high energy oxidizer in the firework launching medicine, make propelling charge self have stronger redox ability, can rapid combustion in the environment of anaerobic or anoxic, make little cigarette propelling charge faster, more complete in weapon barrel internal reaction speed, solved the problem that leaves residual medicine after the gun propellant combustion, improve the propelling charge utilization ratio, guaranteed the consistence of launching effect, and can significantly improve the jetting height of fireworks.
Described catalyzer is ammonium dichromate or ferrocene, the present invention selects the good burningrate catalyst with high heat stability and chemical stability can guarantee the security of firework display, guarantee simultaneously the rapid combustion of little cigarette propelling charge in weapon barrel, improve greatly and set off quality.
Described tranquilizer is amylalcohol or pentanoic.
Described tackiness agent is hydroxy-terminated polybutadienes, hydroxy-terminated polybutadienes is liquid at normal temperatures, therefore when the little cigarette propelling charge of preparation, can be not with an organic solvent, the danger such as the environmental pollution of having avoided being caused by solvent, fire, blast, hydroxy-terminated polybutadienes uses as the tackiness agent of the little cigarette propelling charge of preparation, has realized that the operation of preparation is easy, and applicable to the production technique of serialization, automatization, mechanize, can reduce cost.
Described priming explosive is nitroguanidine or nickel hydrazine nitrate.
Described pore whipping agent is carbon black or nitrate (nitrate is ammonium nitrate, SODIUMNITRATE, saltpetre, strontium nitrate etc.), in propelling charge, add a small amount of pore whipping agent, in the process of the little cigarette propelling charge of preparation, make the some pores that differ in size of powder body self-assembling formation, can alleviate like this weight of propelling charge, Cost reduction, simultaneously, the leachy powder body of tool has increased the contact area with air, can improve combustionvelocity and the rate of combustion of propelling charge.
The fast modifying agent of described combustion is Manganese perchlorate or cupric perchlorate.
Generate little cigarette product after each constituent materials of above-mentioned little cigarette propelling charge decomposes, the oxidation capacity of each material is stronger, and water absorbability is little.
Described little cigarette propelling charge particular manufacturing craft compression moulding, its shape is the powder celestial body with a plurality of longitudinal holes, for increasing the burning area of medicine, makes the medicine sufficient combustion, plays accelerate combustion.
Remarkable advantage of the present invention is: the propelling charge that make (1) is used for firework display only can produce little cigarette, environmental protection; (2) can guarantee the emission after weapon barrel in the noresidue medicine; (3) ignition capability of little cigarette propelling charge of the present invention is strong, be easy to be ignited, simultaneously the products of combustion temperature high, strengthened the ability of the effect medicine that ignites greatly; (4) water absorbability is little; (5) the present invention can greatly reduce production costs and save energy.
