Description
Technical field
The invention belongs to firework technical field of pharmaceuticals, more particularly, to a kind of firework high energy composite oxidant composition
Preparation method.
Background technique
Currently, firework manufacturer prepares in the medicament of production firework product, key agents component is oxidant, accounts for medicine
The 50-70% of agent composition sets off for firework and plays a part of burning, explosion oxygen supply.Explosive force that therefore, firework is seted off is strong and weak,
Dangerous or safety, smog and residue number, both depend on oxidant ratio number and type selection.
Now in the art, firework manufacturer is selected and the oxidant that uses all is to switch to use from past potassium chlorate
Potassium hyperchlorate substitution, but wherein the lead production of firework product still maintains potassium chlorate composition.To find out its cause, being because of potassium chlorate
Or effective oxygen-supplying amount of potassium hyperchlorate is high, fusing point is low, thermal decomposition temperature is low, sound is clear and melodious when setting off, paper breaking rate is high and economical fits
With.But due to metal pulvis or organic matter medicament mixed preparing, impact sensitivity and friction sensitivity are up to 100%, to external impact
It is strong with friction-sensitive.Therefore, firework production preparations, storage and transportation, sell use process in be easy to happen explosion accident, cause to produce
The heavy losses of property.In this regard, country is working out fireworks and firecrackers production, is setting off in product safety standard clearly disabling chlorine with potassium
With the high-risk chemical industry drug such as potassium hyperchlorate.
In recent years, firework manufacturing enterprise and scientific research institutions propose many energy in seeking new oxide alternative Process
It is seted off suitable for firework and again safe and environment-friendly chemical raw material is used as oxidant, but the oxidant having is in preparation process
Middle production technology is complicated, and energy consumption is high, makes valuable product, increased costs.Intermediary in some industrial chemicals production processes
Matter contains the substance of serious pollution environment, is unfavorable for environmental protection.
Summary of the invention
For above-mentioned problems existing in the prior art, present inventor to can be suitably used for firework product configuration at present
Chemical raw material has carried out repetition test screening and optimum organization, proposes a kind of new composite oxidant of firework, mentions simultaneously
Gone out the new oxidant method for producing of simple process, the product of preparation can improve firework set off performance and safety is steady
It is qualitative, reduce production cost.
It is an object of the invention to be directed to new composite oxidant and propose a kind of firework high energy composite oxidant combination
The preparation method of object.
For this purpose, the purpose of the present invention is realized by following technical solution：
A kind of preparation method of firework high energy composite oxidant composition, characterized in that it is by the smokeless oxide of high energy, weight chromium
Sour ammonium, potassium nitrate, smokeless adhesive composition carry out processing preparation, i.e. composition each component point by its component and weight fraction ratio
It is not：The smokeless oxide 20-70 parts by weight of high energy, ammonium dichromate 5-10 parts by weight, potassium nitrate 25-65 parts by weight, smokeless bonding
Agent 5-10 parts by weight, 20 parts by weight of sepiolite powder.
Preparation method specifically includes the following steps：
Step 1：It is equipped with the smokeless oxide of high energy and is crushed to 800-1200 mesh；
Step 2：Ammonium dichromate, sepiolite powder and nitre are poured into 80-100 DEG C of water with potassium in proportion simultaneously be sufficiently stirred it is molten
Solution, is then proportionally added into smokeless adhesive, continuously stirs 10-25 minutes, stirs evenly stand-by；
Step 3：By the smokeless oxide powder of high energy, number is added in the solution of step 2 when stirring in proportion, continues to stir 20-
It 35 minutes, stirs evenly；
Step 4：Again by after mixture dewatered drying made from above-mentioned steps 3, it is put into pulverizer and is crushed to 600-1000 mesh, i.e.,
Composite oxidant composition finished product of the invention, water content < 0.2% is made.
The above-mentioned smokeless oxide of high energy is that N- dicyandiamidines Zoamix, two furazan of dinitro azo are one such or two kinds
Mixture.
The preparation method of firework proposed by the present invention high energy composite oxidant composition, the comparison prior art have as follows
Advantages and beneficial effects：
1, using technical solution of the present invention, preparation process is simple, does not have to special processing equipment, less energy consumption, production cost
It is low.
2, due to using the smokeless oxide of high energy, the firework product that its composition is prepared is seted off securely and reliably, without gold
Belong to object residue, micro- cigarette is nontoxic, dustless dye, low-carbon environment-friendly, and drug burning color is limpid, clear, effectively improves firework combustion
The visual effect put.
3, ammonium dichromate provided by the present invention, potassium nitrate, sepiolite powder are all raw material cheap and easy to get, with high energy oxygen
The composite oxidant of the components such as the Zoamix of agent, two furazans composition, can not only make respective oxidisability that must fully play,
And be conducive to generate many new good impact of performance of interaction, such as passivation reaction, improve burn rate, deep oxidation,
More energy generates, improves explosive force, mixes colours, making sound, the raising of oxygen-enriched value etc..
