Abstract
The invention discloses a pyrotechnic composition used for fireworks without smoke and smell; when the pyrotechnic composition is used as firework emission gunpowder, the components and the weight percentage of the pyrotechnic composition are: 50 to 65 percent of nitro-cotton and 35 to 50 percent of nickel hydrazine nitrate; when the pyrotechnic composition is used as firework down-lead gunpowder, the components and the weight percentage of the pyrotechnic composition are: 85 to 95 percent of nitro-cotton and 5 to 15 percent of the nickel hydrazine nitrate; when the pyrotechnic composition is used as firework effect gunpowder, the components and the weight percentage of the pyrotechnic composition are: 65 to 75 percent of nitro-cotton, 2 to 15 percent of nickel hydrazine nitrate and 10 to 30 percent of colorant; the pyrotechnic composition is uniformly mixed by adopting a common method. The preparation technique of the pyrotechnic composition prepared by the prescription is simple; the friction sensitivity and the impact sensitivity of the pyrotechnic composition after being mixed are lower; the chemical stability is good and the pyrotechnic composition has no smoke and smell when burning; compared with the prior product, the safety and environment protection properties of the pyrotechnic composition are greatly improved; the pyrotechnic composition can be broadly applied to various products such as high altitude display shells, combined pot flowers, stage fireworks and toy fireworks, and so on.
Description
Technical field
The present invention relates to a kind of firework gunpowder composition of fireworks pyrotechnic composition composition, particularly a kind of smoke-free and tasteless.
Background technology
At present, when preparation fireworks pyrotechnic composition, the oxygenant that uses is based on perchlorate (as potassium perchlorate, ammoniumper chlorate) or nitrate, the pyrotechnic composition that these materials and combustible agent etc. are mixed with, though the Potcrate that safety performance adopts than before etc. has had raising, the following problem of this series products ubiquity:
When setting off, produce big smog, influence visual effect; Though some smog is less, can produce unpleasant sharp aroma, these smog and smell serious environment pollution.In the current society that environmental consciousness is strengthened day by day, this shortcoming of firework product has seriously restricted the development of industry.
Summary of the invention
Technical problem to be solved by this invention is the firework gunpowder composition of smoke-free and tasteless when a kind of setting off is provided.
In order to address the above problem, the technical solution used in the present invention is, a kind of firework gunpowder of smoke-free and tasteless,
When it launched drug use as fireworks, its component and weight percentage were:
Nitro-cotton 50%---65% nickel hydrazine nitrate 35%---50%
Its preferable range is: nitro-cotton 55%---60% nickel hydrazine nitrate 40%---45%
When its during as the fireworks leads drug use, its component and weight percentage are:
Nitro-cotton 85%---95% nickel hydrazine nitrate 5%---15%
Its preferable range is: nitro-cotton 87%---92% nickel hydrazine nitrate 8%---13%
When its during as the firework effect drug use, its component and weight percentage are:
Nitro-cotton 65%---75% nickel hydrazine nitrate 2%---15% tinting material 10%---30%.
Its preferable range is: nitro-cotton 67%---73% nickel hydrazine nitrate 5%---12% tinting material 15%---25%.
Composition of the present invention adopts the general method uniform mixing to form, and can be used for making effect medicine, propelling charge or the lead-in wire medicine of all kinds of fireworks.
Combustible agent nitro-cotton among the present invention is by cellulose macromolecule ([C
6H
7O

3] n) make cellulose nitrate with nitric acid generation chemical reaction, be called soluble cotton or nitro-cotton traditionally, its kind and derived prods are a lot, and for the consideration of production cost, preferably adopting with the nitro-cotton among the present invention is main single-base powder, double-base powder or its mixture of forming.
Nickel hydrazine nitrate is the abbreviation that nitric acid three hydrazines close two nickel, and coordination formula is [Ni (N
2H

2, be a kind of complex primary explosive, it has, and manufacturing process is simple, good product performance and stay-in-grade characteristics.Nickel hydrazine nitrate does not chemically react to red copper, aluminium, iron and steel disc etc.; Very stable under (50 ± 1) ℃ long-term heating, moisture uptake seldom; X-ray irradiation is not changed.The mother liquor reusable edible in preparation process particularly, essentially no trade effluent has been protected environment.Based on the above-mentioned characteristic of this material, technical solution of the present invention adopts its oxygenant as the fireworks pyrotechnic composition.
In order to form various colour effects, described tinting material is meant one of strontium nitrate or Strontium carbonate powder (generation blushed flame), nitrate of baryta or barium carbonate (green flame), Sodium Silicofluoride or sodium oxalate (yellow flame), cupric oxide (blue flame) and zirconium, titanium (gold or silver color Mars).More than each material all are the painted modeling agents of flame well-known in the art, in component ratio of the present invention, use the realization all do not influence the object of the invention.
Adopt the pyrotechnic composition of above-mentioned formulation, preparation technology is simple, and it is lower to mix its friction sensitivity of back and impact sensitivity, and chemical stability is good, smoke-free and tasteless when particularly burning.With respect to product in the past, its Safety and Environmental Protection is enhanced.Be widely used in products such as various high altitude fireworks display projectiles, combination potted flower, stage fireworks, toy fireworks.
Embodiment
Embodiment 1: pyrotechnic composition of the present invention is during as the firework effect drug use, press in the table 1 each component formulated and weight percent with each component uniform mixing, getting 25 grams then produces ordinary process according to firework and builds in steel cylinder and ignite and (for getting rid of smog that the papery burning produced and smell to the influence of experiment effect, do not adopt paper materials such as paper web or paper ball; Be the burning situation behind the aids drug fitted tube (ball), the sealing of above-mentioned steel cylinder one end is built behind the medicine capping of the other end mud layer and is established jet hole), and with appearance method smog, the smell of each prescription are tested, in table 1, listed assay:
