Abstract
The invention discloses a colorful trace fume star used in fireworks. The star consists of an effect agent core, an intermediate agent isolation layer and an ignition agent layer. A layer of intermediate agent is stuck on the effect agent core granules as the intermediate agent isolation layer; and a layer of black powder is stuck on the intermediate agent isolation layer as the ignition agent layer. The effect agent core comprises the following ingredients by weight: 15-30 parts of ammonium perchlorate, 5-15 parts of a colorant, 50-75 parts of single-base and double-base agent and 0-5 parts of magnalium. The intermediate agent comprises the following ingredients by weight: 20-35 parts of potassium perchlorate, 5-15 parts of the colorant, 50-75 parts of the single-base and double-base agent and 0-5 parts of the magnalium. The colorful trace fume star used in fireworks generates fume which is less than 30% of that of the existing agent after burning, and has good moisture resistant performance and long shelf life; and visual observation at the burning field proves that burning rate, lightness and color saturation of the star achieve or exceed the effects of the existing products.
Description
Technical field
The present invention relates to a kind of fireworks firework medicament composition, particularly a kind of micro-smoke colorful bright bead for firework.
Background technology
In the prior art, fireworks all are with potassium hyperchlorate with colorful bright bead, and barium nitrate etc. are made main oxidant, make main combustible with alloy, have closed PVC etc. simultaneously and have helped adhesives such as toner, phenolic resins, make under the negative oxygen balance state of height.For example: composition of the bright pearl of ruddiness and ratio of weight and number are: 47 parts of potassium hyperchlorates, 20 parts of strontium carbonates, 20 parts of magnadures, PVC8 part, 8 parts of resins, 7 parts of shellac.Therefore, there is K in the product
2O, BaO, AL
2O
3, burn a large amount of particulate flue dust such as C of insufficient generation of MgO and adhesive.These smog not only make concentrates the large-scale fireworks party firework display effect of setting off adversely effected, and causes bigger pollution to setting off a near urban air.And in the development of smoke less fire cracker,, attempt to solve the big problem of smog though there is the people to replace potassium hyperchlorate to make oxidant ammonium perchlorate, and all run into two problems: the one, ammonium perchlorate can not coexist with potassium nitrate.But the exploitation of at present smokeless ignition powder is also very immature, and ignition powder can only adopt traditional black powder ignition powder in the practice, and ammonium perchlorate can carry out interface ion with the potassium nitrate in the black powder and exchange and generation ammonium nitrate.Ammonium nitrate can seriously absorb water and make the very fast inefficacy of medicine; The 2nd, the main smokeless single, double original washing powder ignition temperature of combustible is low, and the lightness that bright pearl is aloft seted off is too little, and firework display effect is not good enough.
Summary of the invention
In order to overcome above-mentioned defective, technical problem to be solved by this invention is, only produce micro-smog after a kind of burning is provided, and moisture effect is good, combustion speed, lightness, the very desirable micro-smoke colorful bright bead of color saturation.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is, micro-smoke colorful bright bead for firework, and it is made up of effect medicine core, a connective absciss layer and ignition powder layer respectively from inside to outside.
The component and the ratio of weight and number of described effect medicine core are: ammonium perchlorate 15-30 part, and colouring agent 5-15 part, single, double original washing powder 50-75 part, magnadure 0-5 part mixes the back granulation by conventional method, oven dry;
The component of described medicine and ratio of weight and number are: potassium hyperchlorate 20-35 part, and colouring agent 5-15 part, single, double original washing powder 50-75 part, magnadure 0-5 part mix by conventional method;
Single, double original washing powder is well smokeless adhesive through the small molecular organic solvent dissolving, therefore only need spray small molecular organic solvents such as an amount of ketone, alcohol, ether, ester on described effect medicine core grain, the single, double original washing powder that dissolves its surface is made adhesive and is stained with connective absciss layer between described medicine conduct of one deck; Between the connective absciss layer is outer is stained with one deck black powder as the ignition powder layer by known manner.
Effect medicine core of the present invention adopts ammonium perchlorate as oxidant, adopt single, double original washing powder as main reducing agent, all be gaseous product after the reaction, add amount of colorant and also can not form too big smog, add the lightness that the small amount of magnesium aluminium alloy helps to increase bright pearl burning.Between the connective absciss layer mainly be as fine and close isolation layer, make the moisture of outside can not enter effect medicine core, potassium nitrate in the ignition powder can contact with ammonium perchlorate in the effect medicine core and carry out interface ion and exchange.And a medicinal potassium hyperchlorate replaces ammonium perchlorate, can increase some smog a little, but because consumption is little, so influence is little.Ignition powder adopts existing general black powder to get final product.
In order to form various colour effects, described colouring agent is selected from strontium nitrate or strontium carbonate (generation ruddiness); Barium nitrate or brium carbonate (green glow); Prodan, hexafluoro sodium aluminate (common name ice crystal) or sodium oxalate (gold-tinted); Cupric oxide (blue light).More than each material all are flame colouring agents well-known in the art, in component ratio of the present invention, use the realization all do not influence the object of the invention by known manner.
The specific embodiment
Embodiment 1: this routine described micro-smoke colorful bright bead for firework is a ruddiness.
Effect medicine core is made: get 25 parts of ammonium perchlorate by ratio of weight and the number of copies, and 15 parts of strontium carbonates, it is the adhesive granulation with the polyvinyl alcohol that single double-basis powder mixes the back by conventional method for 60 parts, oven dry;
Between medicine make: get 20 parts of potassium hyperchlorates by ratio of weight and the number of copies, 15 parts of strontium carbonates, 60 parts in single double-basis powder, 5 parts of magnadures mix by conventional method, and are standby;
Spray an amount of ethanol on effect medicine slug particle, be stained with an interlayer medicine again, it is better that described medicine layer thinnest part is not less than the 1mm effect, and a medicine layer is stained with one deck black powder outward again and makes the ignition powder layer, and effect was better when the thickness of ignition powder layer was 0.5-1mm.Promptly get described micro-smoke colorful bright bead for firework.
Embodiment 2: this routine described micro-smoke colorful bright bead for firework is a blue light, is with the difference of embodiment 1.The composition and the ratio of weight and number of effect medicine core are: 15 parts of ammonium perchlorate, 5 parts of cupric oxide, 75 parts in single double-basis powder; Between the composition and the ratio of weight and number of medicine be: 20 parts of potassium hyperchlorates, 5 parts of cupric oxide, 70 parts in single double-basis powder, 5 parts of magnadures.All the other are all identical with embodiment 1.
