Abstract
A colour flash flake for fireworks with light and sound effects is prepared from nitroguanidine, potassium perchlorate, nitrocellulose, chlorinated paraffine wax 70, magnesium powder, stronium sulfate and adhesive through mixing and rolling. Its advantages are high stability for storage, low cost, high flash frequency and less environmental pollution.
Description
Technical field: the invention discloses a kind of colour flash card that is used to produce fireworks.
Background technology: when making firework product such as rocket, potted flower, spraying decoration, fireworks display, add flash card usually and reach firework display snuff effect, have the effect of luminous, sound equipment, snuff during the flash card outburst.Existing flash card is that the employing ammoniumper chlorate is main oxygenant, and adds the Strontium Sulphate oxygenant, and the magnesium powder is a reductive agent, the flash card of the bead that adding tackiness agent stirring ball processes.Though this flash card can satisfy people's appreciation effect, but still have that production cost is higher, flicker frequency weak point, not anti-storage; Pollute shortcomings such as bigger, this flash card easily resolves into additional compounds with airborne oxygen reaction owing to adopted the extremely strong ammoniumper chlorate of water absorbability as main oxygenant in process of production in storage process.Though the producer that has adopts damp proof material parcel flash card, the isolation flash card contacts with external substance, and still therefore the effect that can not be satisfied with, is necessary existing technology is improved.
Technical scheme: the object of the present invention is to provide the colour flash card that a kind of shelf characteric is stable, production cost is lower, flicker frequency is long, the feature of environmental protection is good.
The present invention adopts following scheme to realize: gets by weight,
Nitroguanidine 30-40% potassium perchlorate 4-12% soluble cotton 8-16%
Clorafin 70 5-10% magnesium powder 15-19% Strontium Sulphate 21-25% mix above-mentioned materials, process the method processing of flash card routinely, add the organic binder bond that is equivalent to medicine total amount 3-7%, make the flash card of small pearl body shape through stirring ball.
Reaction principle of the present invention is as follows: it is main oxygenant that the present invention adopts nitroguanidine, the characteristics that it has that low, decomposition heat little, non-hygroscopic, the shelf characteric of fusing point is stable, decomposition temperature is low, cheap, contamination-free discharges during burning, be equipped with simultaneously decomposition temperature higher, close the big potassium perchlorate of oxygen amount and Strontium Sulphate is formed oxygenant.Reductive agent (combustiblematerials) is that metal magnesium powder and soluble cotton are formed, and the magnesium powder is selected moistureproof magnesium powder for use, the magnesium powder as reductive agent have good stability, shelf characteric is stable, soluble cotton be a kind of contain can, the reductive agent of smokeless, environmental protection.After flash card was ignited, after vexed combustion (the vexed combustion of nonflame) after a while, the flash card internal temperature reached its detonation point, then produces detonation, produced red flash of light and sent the sound, and flash card thereby outburst are broken.The temperature of fragmentation body sharply descends and forms the vexed combustion phase like this, and the fragmentation body when temperature reaches bursting point once more in the body, produces the snuff of fragmentation body for the second time again through behind one section heat accumulation again, and even the snuff of broken body repeatedly, reaches the alternately effect of flicker.
In the present invention, adopt the higher potassium perchlorate of lower nitroguanidine of decomposition temperature and decomposition temperature, Strontium Sulphate to reach effective control chemical reaction velocity with the reductive agent reaction respectively, thereby the time of control outburst process reach the frequency that the control flash card glistens.In reaction, add clorafin 70 as tinting material, adjust the color saturation of flash card.When making the slower flash card of flashing rate, increase nitroguanidine, nitrocotton cellulose content, the content that reduces potassium perchlorate, Strontium Sulphate reaches the combustion speed when increasing outburst.As making flashing rate faster during flash card, then increase the content of potassium perchlorate, Strontium Sulphate, reduce nitroguanidine, nitrocotton cellulose content, reach the vexed combustion time that increases.
The present invention has that shelf characteric is stable, flashing rate is even, and the flashing rate span of control is big, can reach more than 3 seconds at interval, and characteristics such as color is saturated, production cost is lower, good environmental protection are a kind of high-performance environment-friendly pyrotechnics compositions.
Specific embodiment: example 1: get by weight
Magnesium powder 19% Strontium Sulphate 21% nitroguanidine 32%
Soluble cotton 10% potassium perchlorate 12% clorafin 70 6% mixes above-mentioned materials, adds 6% the organic binder bond that is equivalent to the medicine total amount, makes the flash card of small pearl body shape through stirring.Example 2: get by weight
Magnesium powder 16% Strontium Sulphate 24% nitroguanidine 38%
Soluble cotton 8% potassium perchlorate 6% clorafin 70 8% mixes above-mentioned materials, adds 7% the organic binder bond that is equivalent to the medicine total amount, makes the flash card of small pearl body shape through stirring.Example 3: get by weight
Magnesium powder 17% Strontium Sulphate 23% nitroguanidine 34%
Soluble cotton 11% potassium perchlorate 8% clorafin 70 7% mixes above-mentioned materials, adds 4% the organic binder bond that is equivalent to the medicine total amount, makes the flash card of small pearl body shape through stirring.
