Abstract
The invention discloses an environment-friendly safe gunpowder oxidizer of fireworks and firecrackers, and belongs to the chemical field. The environment-friendly safe gunpowder oxidizer is mixed and made by potassium hyperchlorate, strontium nitrate, barium nitrate and flame retardant material. The gunpowder oxidizer is characterized in simple prescription, good safety, no potassium chlorate, no sulfur, etc., and is widely used in the industries such as firecrackers, fireworks, etc., and is an ideal safe gunpowder oxidizer.
Description
Affiliated technical field
The present invention relates to chemical field, particularly a kind of environment-friendly type safety fireworks firecracker gun powder oxidant of fireworks sector application.
Background technology
Fireworks are risen in China, and its employed gunpowder is exactly the black powder of one of the four inventions in Ancient Chinese generation, owing to contain saltpetre and sulphur in the black powder, less stable very easily causes security incident, and native land man uses this restriction.Modern age gunpowder with Potcrate as oxygenant, fast, the sound foot of the firecrackers reaction of making by this kind gunpowder, but because Potcrate is a kind of strong oxidizer, low, the poor heat stability of fusing point, its Tammann temperature is 42 ℃, decomposition temperature is 360 ℃, and Potcrate and inflammable articles such as sulphur, phosphorus, carbon etc. mix, and are clashed into or the easy blast on fire that rubs; And Potcrate type gunpowder uses sulphur in a large number; and the sulphur very active combustiblematerials that is a kind of chemical property itself; can invade the stability of destroying Potcrate in the Potcrate lattice; according to detection; Potcrate type gunpowder friction sensitivity and impact sensitivity are 100%; for this reason, the General Office of the State Council in 2002 No. 52 files specify fireworks and firecrackerss industry production forbids to use Potcrate.Recently some occur and do not used the gunpowder of Potcrate, as Chinese patent " a kind of safe firecracker medicine that contains perchlorate " (application number is 200310110406.7), its component is by perchlorate, aluminium powder, four kinds of compositions of sulphur and perlite powder combine, this formula of medicine is simple, composition is few, chemical stability and security are good, chloracid potassium not, solved existing firecracker medicine impact sensitivity, problems such as friction sensitivity height and danger are big, it is low and safe to have mechanical sensitivity, set off advantages such as explosion sound rate and sound level be all excellent, but wherein contain sulphur, can produce sulfide gas after setting off, environment is had certain influence.
Summary of the invention
Technical problem to be solved by this invention provides that a kind of prescription is simple, and security is good, and the fireworks firecracker gun powder oxidant of chloracid potassium and sulphur not.
The technical solution used in the present invention is a kind of environment-friendly type safety fireworks firecracker gun powder oxidant of invention, is become by the mixed raw material of following weight quota: potassium perchlorate 40-80, strontium nitrate 2-10, nitrate of baryta 2-10, fire retardant material 10-40.
Its weight quota mix proportion scheme one: potassium perchlorate 40, strontium nitrate 10, nitrate of baryta 10, fire retardant material 40.
Its weight quota mix proportion scheme two: potassium perchlorate 80, strontium nitrate 2, nitrate of baryta 2, fire retardant material 16.
Its weight quota mix proportion scheme three: potassium perchlorate 70, strontium nitrate 10, nitrate of baryta 10, fire retardant material 10.
Its optimum weight share is: potassium perchlorate 70, strontium nitrate 5, nitrate of baryta 5, fire retardant material 20.
Its fire retardant material can be a perlite powder, also can be the light calcium carbonate powder, or other aphlogistic meals.
Environment-friendly type safety fireworks firecracker gun powder oxidant of the present invention adopts potassium perchlorate as main oxygenant, and potassium perchlorate is a kind of heat absorbing type compound, its decomposition temperature height, and chemical property is more stable, and is very low to mechanical impact and friction sensitivity; The mitigate effects that is aided with the more stable ignition dope strontium nitrate of chemical property and nitrate of baryta and fire retardant material again, thereby invention prescription is simple, also not chloracid potassium and sulphur, impact sensitivity and friction sensitivity are extremely low, kindling temperature (being flash point) is very high, so its security is fine.Its product detects through Hunan Center for Fireworks and Crackers Products Safety ﹠ Quality Supervision and Testing, and the key technical indexes is better than national standard (GB10630-2004), specifically sees Table one:
Table one the key technical indexes
| Sequence number | Interventions Requested | Assay | National standard | Result of determination |
| 1 | Impact sensitivity | 0 | ≤50 | Qualified |
| 2 | Friction sensitivity | 0 | ≤60 | Qualified |
| 3 | Rate of moisture absorption | 0.81 | ≤2.0 | Qualified |
| 4 | Bursting point | 616℃ | 350℃ | Qualified |
What table two was that Hunan company produces is the key technical indexes of the safety and environmental protection medicament of oxygenant with the perchlorate, and the safety and environmental protection medicament of the said firm is domestic more advanced product, the promotion of being State Administration of Quality and Technical Supervision.
Table two the key technical indexes
| Sequence number | Interventions Requested | Assay | National standard | Result of determination |
| 1 | Impact sensitivity | 0 | ≤50 | Qualified |
| 2 | Friction sensitivity | 8 | ≤60 | Qualified |
| 3 | Rate of moisture absorption | 1 | ≤2.0 | Qualified |
| 4 | Bursting point | 422℃ | ≥350℃ | Qualified |
Embodiment
Below in conjunction with embodiment, the present invention is further illustrated.
Get potassium perchlorate 70 grams, strontium nitrate 5 grams, nitrate of baryta 5 grams, perlite powder 20 grams of finely powdered, add reductive agent aluminium silver powder 35 grams again, under low temperature, security context, working specification according to national regulation, mix lightly, the gunpowder of this dosage can load 1260 in special red firecrackers (annotate: 1.1 centimetres of diameters, 3.2 cm long), according to the ordinary method powder charge, insert and draw, seal.
Claims (3)
1, a kind of environment-friendly type safety fireworks firecracker gun powder oxidant is characterized in that being become by the mixed raw material of following weight quota: potassium perchlorate 40-80, strontium nitrate 2-10, nitrate of baryta 2-10, fire retardant material 10-40.
