Abstract
The present invention discloses a firework gunpowder composition for firework sounding beads. According to the present invention, the composition comprises copper oxide, aluminum-magnesium alloy powder, a binder and an accelerator, wherein the accelerator is a mixture comprising one or a plurality of substances selected from an antimony oxide, a zinc oxide, a tin oxide and a manganese oxide according to any ratio; the composition can achieve the sounding bead effect based on the thermodynamic adjusting effect of the accelerator without the lead compound (such as lead tetroxide, lead oxide, and the like) or bismuth compound (such as bismuth oxide, bismuth subcarbonate, and the like), wherein the sounding value of the sounding bead is high, and the cost is low; and in the firework gunpowder composition containing the lead compound or bismuth compound, the sounding value of the sounding bead can be increased by using the accelerator.
Description
Technical field
The present invention relates to a kind of rattle of fireworks.
Background technology
Fireworks produce in, rattle also known as rattle, be exactly in firework product by pyrotechnic composition rolling patent medicine pearl, light rear main generation effects,sound, send dazzling white flash effect simultaneously.Because its volume is little, manufacture craft is more simply too much than blast, so gain great popularity in firework product making processes always.
According to common practise, blast effectiveness will be produced in pyrotechnics product, pyrotechnic composition must be seated in a sealing and in durable container, igniting after pyrotechnic composition, producing high temperature and high pressure gas, when this high temperature and high pressure gas is when breaking through the constraint of container instantaneously by the quick response of pyrotechnic composition, just have huge energy sharply to discharge, vibrate air, sends the sound, can produce blast effectiveness.
But rattle is completely exposed at reaction process Chinese medicine bead, does not just have container pack pyrotechnic composition at all; Although the several drugs of rattle thermite reaction can occur after ignition in addition, release a large amount of heat, do not have gaseous product to generate in reaction, also just can not produce high temperature and high pressure gas.That is, in the reaction process of rattle effect medicine, two primary conditions forming blast all do not have at this central one, and its out and out effect that can produce blast.So in prior art, the formula of rattle or rattle is very single, be difficult to realize change.
Traditional rattle formula is mainly with red lead powder (Pb
3o
4), cupric oxide powder (CuO), magnesium aluminum-alloy powder (Mg
4al
3), add that appropriate tackiness agent is by making particulate state powder after the mixing of certain ratio uniform.Be harmful to environment due to leaded, prohibited use by some place of export country; Its quality stability also has much room for improvement simultaneously.For this reason, the surrogate of the tri-lead tetroxide searched out in the industry is bismuth oxide.Also Bismuth carbonate or other bismuth compound (can decompose or be oxidized other bismuth compounds generating bismuth oxide, as bismuth sulfide, Bismuth Subcarbonate etc. after bismuth oxide or heating) have similar effect to have patent documentation to think.But, due to bismuth compound itself costly; Adopt the rattle after surrogate too high to the quality requirements of aluminium-magnesium alloy powder in formula simultaneously; These two aspects all improve the cost of product.And substitute after rattle effect good not, sound value is not high.
Summary of the invention
In order to solve above-mentioned drawback, technical problem to be solved by this invention is, provides a kind of firework rattle pyrotechnic composition composition, does not rely on lead compound or bismuth compound can realize rattle effect, and the sound value of rattle is high.In order to solve the problems of the technologies described above, the technical solution used in the present invention is, a kind of pyrotechnic composition composition for firework rattle, it is characterized in that, said composition comprises cupric oxide, aluminium-magnesium alloy powder, tackiness agent, promotor, and described promotor is selected from the mixture of a kind of or multiple arbitrarily arbitrary proportion in following substances: sb oxide, zinc oxide, tin-oxide, Mn oxide.
In technique scheme, described sb oxide comprises antimonous oxide (weisspiessglanz), antimony peroxide (antimony peroxide); Described tin-oxide comprises tin protoxide (tin protoxide), tindioxide (stannic oxide); Described Mn oxide comprises manganese monoxide, Manganse Dioxide, trimanganese tetroxide.All be applicable to the present invention.Described tackiness agent can adopt the tackiness agent of various firework gunpowder, as water soluble starch, resol, dextrin etc.
Adopt above-mentioned rattle pyrotechnic composition composition, based on the Accommodation on the thermodynamics of above-mentioned promotor, do not rely on lead compound (as tri-lead tetroxide, plumbous oxide etc.) or bismuth compound (as bismuth oxide, Bismuth carbonate etc.) can realize rattle effect, the sound value of rattle is high, and cost is comparatively cheap.In the rattle pyrotechnic composition composition containing above-mentioned lead compound or bismuth compound, use above-mentioned promotor also can play the effect improving rattle sound value.
Preferably, described firework rattle is made up of following substances: cupric oxide, aluminium-magnesium alloy powder, tackiness agent, promotor.
Preferably, described firework rattle is made up of the material of following weight ratio: cupric oxide 5 ~ 80%, aluminium-magnesium alloy powder 15 ~ 40%, tackiness agent 1 ~ 8%, promotor 1 ~ 50%.
Preferably, described for also comprising potassium bichromate in the pyrotechnic composition composition of firework rattle.Potassium bichromate finally serves effective buffer action, has stopped interpenetrating between inner core medicine and external parcel medicine under solvent action, stabilizes the firing property of rattle medicine.Based on potassium bichromate to ripple metallic surface passivation of living, rattle stability is better.
Preferably, described firework rattle is made up of cupric oxide, aluminium-magnesium alloy powder, tackiness agent, promotor, potassium bichromate.
Further, described firework rattle is made up of the material of following weight ratio: cupric oxide 5 ~ 80%, aluminium-magnesium alloy powder 15 ~ 40%, tackiness agent 1 ~ 8%, promotor 1 ~ 50%, potassium bichromate 1 ~ 15%.
The production method of described firework rattle is, each component is through pulverizing, sieving, mix.Add water or alcohol equal solvent is made into particulate matter (being commonly called as pearl processed).Then,
When rattle as spraying decoration class fireworks uses, after described particulate matter drying, with other effect medicines, function medicine mixing fitted tube;
When using as display shell, ground fireworks display, rocket class fireworks rattle, described particulate matter is called inner core medicine pearl, and need first external parcel medicine on inner core medicine pearl outside surface is coated, external parcel medicine is priming.After drying, with other effect medicines, function medicine mixing fitted tube;
Some firework product, as be commonly called as chrysanthemum, time rain product, the design effect of rattle is band sound mixed effect, the i.e. composite grain of effects,sound and other light, chromatic effect, described particulate matter is called inner core medicine, need first coated external parcel medicine on inner core medicine, the formula of external parcel medicine comprises priming and other effect medicines etc., as required by known Content adaptation.After drying, with other effect medicines, function medicine mixing fitted tube.
Below in conjunction with specific embodiment, the present invention will be further described.
