Abstract
The invention discloses nitrified maize-core smokeless fireworks powder. The nitrified maize-core smokeless fireworks powder is characterized by comprising the following components in parts by weight: 100 parts of crushed maize-core fiber, 50 to 70 parts of nitric acid, 20 to 25 parts of sulphuric acid, 1.5 to 3 parts of diphenylamine, 1.5 to 3 parts of camphor, and 80 to 90 parts of ethyl alcohol, wherein the nitric acid is of 98% in concentration, and the sulphuric acid is 98% fuming sulphuric acid in concentration. The nitrified maize-core smokeless fireworks powder has the advantages of being high in safety, stable in performance, free of smoke, non-toxic, environmentally-friendly, etc. and is widely suitable for preparation of various fireworks and crackers.
Description
Technical field
The present invention relates to a kind of nitrated corn cob smoke less fire cracker medicine, belong to fireworks agent manufacturing technology field.
Background technology
In prior art, general firework product is seted off Shi Douhui and is produced a large amount of smog, and its major cause is all can have K in oxygenant decomposition product
2o, BaO, these metal oxides just produce a large amount of smog while running into moisture when forming cigarette, and the sulphur in combustiblematerials and alloy be also to form one of factor that acid mist drips, and these acid mists drip environmental disruption very large.At present, fireworks industry is due to the main drug material using containing perchlorate composition, so security extreme difference in process for processing and transportation, slightly rub and clash into just and can blast, cause serious loss of life and personal injury and property damage, bring heavy pressure at heart to the producer and the manager of fireworks enterprise.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of nitrated corn cob smoke less fire cracker medicine for fireworks and firecrackers is provided, have the advantages that security is good, rate of moisture absorption is low, product performance are stable, smokeless, to overcome, in prior art, very easily blast and defect that product is seted off the larger smog of generation.
Technical solution of the present invention is:
A kind of nitrated corn cob smoke less fire cracker medicine, it is characterized in that: it adopts zein fiber and nitric acid, sulfuric acid, pentanoic, camphor, alcohol to form, its composition and ratio of weight and number, get corn cob fiber 100 weight parts of pulverizing, nitric acid 50-70 weight part, sulfuric acid 20-25 weight part, pentanoic 1.5-3 weight part, camphor 1.5-3 weight part, alcohol 80-90 weight part, wherein concentration of nitric acid is 98%, the oleum that sulfuric acid concentration is 98%.
Establishing corn cob fiber 100 weight parts processed, get nitric acid 50 weight parts, sulfuric acid 20 weight parts, pentanoic 1.5 weight parts, camphor 1.5 weight parts, alcohol 80 weight parts.
Establishing corn cob fiber 100 weight parts processed, get nitric acid 70 weight parts, sulfuric acid 25 weight parts, pentanoic 3 weight parts, camphor 3 weight parts, alcohol 90 weight parts.
Technical process of the present invention is: by after the corn cob fiber choosing of pulverizing, with appropriate soda ash, add water and stir immersion 2-3 days, it is mainly impurity elimination degrease, except sugar, water cleans up again, after Air drying, carry out digestion process, add by ratio of weight and the number of copies appropriate concentrated nitric acid and the vitriol oil of being fuming to drop into uniform stirring in reactor, normal temperature digestion reaction 1 hour, then take out corn cob fiber after nitration reaction rinsing and centrifugal drying again, be 1-2 hour time of drying, temperature keeps 100 degree left and right, after finally adding the adaptive pentanoic of measuring and camphor to be mixed evenly with alcohol dissolving mixt used as stabilizers, again pulverize, fineness of powder is 120 orders, in water content 2%, make the nitrated corn cob smoke less fire cracker medicine of described invention.
The present invention is a kind of nitrated corn cob smoke less fire cracker medicine, and its feature and beneficial effect are:
Owing to adopting corn cob, make main raw material, draw materials extensively, be conducive to the regeneration of waste agronomic crop resource, powder fiber after simultaneously pulverizing with corn cob carries out nitration reaction and makes nitrated corn cob smoke less fire cracker medicine through the mix acid liquor of concentrated nitric acid and the vitriol oil of being fuming, its powder performance is stable, rate of moisture absorption is low, and the firework product producing not moisture-sensitive goes mouldy, and is conducive to improve the quality of firework product.And the security of obtained nitrated corn cob smoke less fire cracker medicine is good, generally rubs and clash into the casualty accident of can not blasting.Smokelessly nontoxic while setting off with the various classification firework products of the present invention's preparation, can meet the requirement of safety, environmental protection, relatively there is smoke product more pure and fresh gorgeous, view and admire visual effect better, be adapted to the preparation of the products such as various display shells series, combined firework is serial, cold light firework is serial, stage fireworks, can be used for propelling charge, spraying decoration medicine, ignition powder, open the medicament preparations such as luxuriant medicine, and cost is low, be the smokeless medicaments of a kind of desirable fireworks.
Embodiment
Below in conjunction with preferred embodiment, the present invention is further described.
A kind of nitrated corn cob smoke less fire cracker medicine of the present invention, feature is: its component mainly utilizes discarded corn cob vegetable fibre to make nitrated carrier, can certainly select maize straw vegetable fibre to make nitrated carrier, can also adopt other discarded vegetable fibres to make nitrated carrier, be conducive to the regeneration of waste plant straws fiber, reduce the cost of firework product, environmental and safety.It prepares component of the present invention and ratio of weight and number is: the corn cob that is equipped with standby 100 weight parts, get the nitric acid 50-70 weight part of 98% concentration, the oleum 20-25 weight part of 98% concentration, pentanoic 1.5-3 weight part, camphor 1.5-3 weight part, alcohol 80-90 weight part.
Establishing zein fiber 100 weight parts processed, get nitric acid 50 weight parts, sulfuric acid 20 weight parts, pentanoic 1.5 weight parts, camphor 1.5 weight parts, alcohol 80 weight parts.
Establishing corn cob fiber 100 weight parts processed, get nitric acid 70 weight parts, sulfuric acid 25 weight parts, pentanoic 3 weight parts, camphor 3 weight parts, alcohol 90 weight parts.
The above-mentioned embodiment of description of the invention is only for technical scheme of the present invention is clearly described, and can not be interpreted as the present invention is made to any restriction.The present invention has known multiple alternative in the art, departing under the prerequisite of essential meaning of the present invention, all falls into protection scope of the present invention.
