Abstract
The color fireworks flash sheets are produced with nitro guanidine potassium, nitrocellulose, chlorinated paraffin 70, magnesium powder and coloring agent and through adhesion with organic adhesive and balling. It is used mainly in toy rocket, spraying flower and other fireworks product to produce blasting, flashing and sounding effects. It has stable storing performance, low production cost, long flash time and good environment protecting performance. It may be used as the substitute of available flash sheets.
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, outburst during the flash card outburst.Existing flash card is that the employing ammoniumper chlorate is main oxygenant, and adds the oxide sulfate agent, 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, still can not obtain satisfied effect, therefore, is necessary existing technology is improved.
Summary of the invention:
Technical problem to be solved by this invention provides 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: get by weight
Nitroguanidine 14-55% soluble cotton 1-16%
Clorafin 5-12% magnesium powder 8-40% tinting material 4-60%
Above-mentioned materials is mixed, process the method processing of flash card routinely, add the organic binder bond that is equivalent to medicine total amount 1.5-7%, make the flash card of small pearl body shape through stirring ball.
Tinting material is made up of in the mixture of nitrate of baryta, nitrate of baryta and Strontium Sulphate, Strontium Sulphate and potassium perchlorate, cupric oxide and potassium perchlorate, Strontium Sulphate and cupric oxide and potassium perchlorate any one.
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 are equipped with potassium perchlorate and the Strontium Sulphate that decomposition temperature is higher, oxygen level is big simultaneously and form 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 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 chlorine-supplying agent, adjust the color saturation of flash card.When making the slower flash card of flashing rate, increase nitroguanidine, Strontium Sulphate or cupric oxide content, the content that reduces potassium perchlorate or nitrate of baryta, nitroguanidine reaches the purpose of the flicker frequency that slows down.As making flashing rate faster during flash card, then increase potassium perchlorate, nitrocellulosic content, reduce nitroguanidine, Strontium Sulphate content, reach the purpose that adds frequency.
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.
