Abstract
The invention provides a composite oxidant for fireworks. The composite oxidant consists of the following raw materials in percentage by weight: 20 to 55 percent of potassium perchlorate, 40 to 65 percent of barium nitrate, 1 to 10 percent of monobase powder and 2 to 8 percent of ferric oxide. The composite oxidant for the fireworks has safe performance and low price; the moisture absorption rate is less than 1 percent; the friction sensitivity and the impact sensitivity are zero; and the fireworks produced by the oxidant have the explosion rate and the paper breaking rate of over 98 percent and have safety, stability and long storage time.
Description
Technical field
The present invention relates to a kind of oxygenant, be specifically related to a kind of firework composite oxidant.
Background technology
In the fireworks and firecrackers industry,, realize safety in production for guaranteeing the people's life security, Potcrate is ordered to forbid to use by country in Sparkler oxidant, because of its friction and impact sensitivity high, friction and clash into coefficient and be 100%, the careless slightly accident of very easily blasting in actual mechanical process.Hyperoxia acid potassium is made Sparkler oxidant, and cost is too high again, how just can develop operational safety, firework display effect is good, cost is low again oxygenant, is a urgent and difficult problem in the national same industry.
Chinese patent such as application number are that 03118270.4 (Firecrackers oxidant) and application number are that 200410016899.2 (firecrackers safety oxygenants) all disclose the Firecrackers oxidant that substitutes existing Potcrate oxygenant, this oxygenant rate of moisture absorption height, the fireworks that uses this oxygenant to make, its rate of explosion and paper breaking rate are not satisfactory, effect is not really stable, remaining time is short, and the production cost height, is difficult to popularize in an all-round way use.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide that a kind of safety, rate of moisture absorption are low, friction sensitivity and impact sensitivity are zero firework composite oxidant, use the firework rate of explosion and the paper breaking rate height of this oxidant production, friction sensitivity and impact sensitivity are extremely low, remaining time is long, effect stability, production cost is low.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of firework composite oxidant is characterized in that being made up of following raw materials by weight percent:
Potassium perchlorate 20-55%, nitrate of baryta 40-65%, single original washing powder 1-10%, ferric oxide 1-8%.
Its preparation method is: above-mentioned each raw material is crossed the 100-160 mesh sieve respectively, the raw material after sieving is added to mix stirring in the mixing machine then, mix once more behind the 100-120 mesh sieve excessively, be finished product after the packing.
The preferred technical solution of the present invention: a kind of firework composite oxidant is characterized in that being made up of following raw materials by weight percent: potassium perchlorate 41-55%, nitrate of baryta 41-55%, single original washing powder 1-10%, ferric oxide 1-8%.
Its preparation method is: above-mentioned each raw material is crossed the 100-160 mesh sieve respectively, the raw material after sieving is added to mix stirring in the mixing machine then, mix once more behind the 100-120 mesh sieve excessively, be finished product after the packing.
In the raw material of the present invention, potassium perchlorate and nitrate of baryta are oxygenant, and single original washing powder is a non-blushing thinner, and existing dampproof effect has catalytic effect again, and ferric oxide is a catalyzer, promote the oxidation agent speed of response.
The present invention compared with prior art has the following advantages: firework composite oxidant performance safety of the present invention, and low price, rate of moisture absorption is lower than 1%, and friction sensitivity and impact sensitivity are zero; Adopt the firework of oxidant production of the present invention, rate of explosion and paper breaking rate be all more than 98%, safety and stability, and remaining time is long, explosive sound level 〉=130dB.
Below by embodiment the present invention is described in further detail.
