Abstract
The present invention discloses a kind of flame retardant of pyrotechnic composition, it includes the component of following ratio by weight: shellac powder: 15%-25%, glutinous rice flour: 5%-15%, charcoal powder: 3%-10%, and surplus is bamboo powder, wood powder or the bamboo powder of -200 mesh of 120 mesh and the mixture of wood powder.Using flame retardant of the invention, delay the combustion efficiency of pyrotechnic composition more preferable, while there is preferable stability and be also possible that pyrotechnic composition light for issuing in burning is more bright-coloured.
Description
Technical field
The present invention relates to fireworks pharmaceutical techniques field more particularly to a kind of flame retardants of pyrotechnic composition.
Background technique
Fireworks medicine is usually made of propellant powder, fire-retardant medicine and colored-light composition.Wherein propellant powder is predominantly so that combustible
Burning, is usually made of all kinds of oxidants and combustible.The effect of fire-retardant medicine be reduce propellant powder burning velocity, delay it is coloured
The fluorescent lifetime of photo etching.
The Chinese patent of Publication No. CN1763470A discloses a kind of " application of the dicyandiamide in fireworks medicament ", uses
Dicyandiamides more than 100 mesh is added in fireworks medicament as fire retardant, and playing reduces burning velocity, extends the colorful light-emitting time
Effect.But the prior art, only with the medicament of single dicyandiamide, retarding action is not obvious, while it also can not be with
The other components of fireworks medicament generate synergistic effect, are only capable of being purely by way of fire retardant use.In addition dicyandiamide is as chemical agent,
Its use cost is also higher.
Summary of the invention
Technical problem to be solved by the present invention lies in, for the above-mentioned deficiency of the prior art, propose it is a kind of cost is relatively low,
The flame retardant of good flame retardation effect and the more bright-coloured pyrotechnic composition of color when can make firework display.
The technical solution used to solve the technical problems of the present invention is that proposing a kind of flame retardant of pyrotechnic composition, by weight
Part includes the component of following ratio:
Shellac powder: 15%-25%, glutinous rice flour: 5%-15%, charcoal powder: 3%-10%, surplus are -200 purpose of 120 mesh
The mixture of bamboo powder, wood powder or bamboo powder and wood powder.
Bamboo powder and wood powder are oxidizers under normal particle sizes, but when bamboo powder, the granularity of wood powder reach 120 mesh with
After upper, extremely difficult burning, becomes flame retardant.The present invention using the higher bamboo powder of granularity, wood powder as major ingredient, have it is lower at
Sheet and preferable flame retardant effect, while being also possible to be that color is more bright-coloured to lure so that fireworks burn after using bamboo powder and wood powder
Cause.
Shellac powder and glutinous rice flour are all preferable flame retardants.Find during the experiment, if only using bamboo powder and wood powder as
Flame-proof material flame retardant effect is unsatisfactory.Flame retardant effect is very ideal after adding shellac powder and glutinous rice flour.
Glutinous rice flour also acts as the effect of adhesive simultaneously, and this product is enabled to make this in practical application to pyrotechnic composition
The other components of product and pyrotechnic composition are preferably bonded together.Glutinous rice powder content must be suitable, if glutinous rice flour too high levels
It may be that pyrotechnic composition sticks into one, pyrotechnic composition too disperses if content is too low, and pyrotechnic composition both cannot form desired
Fountain or bright pearl effect.
Charcoal powder primarily serves toning effect in the present invention, so that entire product is in grey black.The product of grey black can
It is mixed well with the other compositions with pyrotechnic composition.
It further, further include the fragrance powder of parts by weight 1%-3%.
Fragrance powder primarily serves the effect for improving product odour in the present invention.Product process and with other groups of pyrotechnic composition
The working environment of workers can be improved when dividing mixing.
Further, the parts by weight of the flame retardant of the fireworks medicine are as follows: shellac powder: 15%, glutinous rice flour: 5%, charcoal powder:
6%, surplus is the bamboo powder of 120 mesh and the mixture of wood powder.
Further, the parts by weight of the flame retardant of the fireworks medicine are as follows: shellac powder: 20%, glutinous rice flour: 8%, charcoal powder:
3%, surplus is the bamboo powder of 150 mesh.
Further, the parts by weight of the flame retardant of the fireworks medicine are as follows: shellac powder: 25%, glutinous rice flour: 15%, charcoal powder:
10%, surplus is the bamboo powder of 200 mesh and the mixture of wood powder.
The present invention has the following beneficial effects: compared with prior art
1, the virtuous phoenix chemical industry in Liuyang City manages Co., Ltd for this product commission Hunan Entry-Exit Inspection and Quarantine Bureau fireworks explosion
Inspection center detection show that the burn rate of this product is 0.0042mm/S, has very outstanding flame retardant effect, while this
The ignition temperature of product is 309.3 DEG C, may not catching fire under normal storage, traffic condition.
2, after this product being added to arbitrary fountain or bright pearl class fireworks medicament, it can not only play and delay fireworks burning
Effect, while the light color that while also fireworks being burnt issues is more bright-coloured.This product that should be used as flame retardant is
The more bright-coloured concrete principle of the light color issued when what can make fireworks burn is still not clear, and inventor's conjecture may be
Due to the mixture of the thinner bamboo powder of granularity, wood powder or bamboo powder and wood powder make the combustible of pyrotechnic composition burning when smog compared with
It is few, so the color that pyrotechnic composition burns as viewed from visually is more bright-coloured, it is also possible to which this product makes the colored light in pyrotechnic composition
Agent burning is more abundant.
