Abstract
A non-smoke propellant for fireworks contains nitrocotton (30-80 wt.%) and ammonium perchlorate (20-70 wt.%). Its advantages are high safety, environment protection, and low cost.
Description
Technical field
The present invention relates to a kind of propelling charge, particularly relate to a kind of smokeless propellant.
Background technology
At present, the oxygenant that is used to produce firecrackers on market mainly is with Potcrate, potassium perchlorate, and sulphur, saltpetre are main.As everyone knows, Potcrate is a kind of strong oxidizer, is thermopositive reaction when decomposing owing to its, so its susceptibility is very high, mixes when clashing into sulphur, phosphorus, carbon and organic combustiblematerials, and easily generation is burnt and blast, and danger is big when production, transportation, use.Therefore Potcrate is easy to take place security incident when being used for fireworks and firecracker production, causes personal injury and property damage.State Council has issued No. 52 file specially in 2002 for this reason, forbids producing fireworks with the Potcrate preparation.And potassium perchlorate because its price is high, generates increase in production, so influence its popularization and use when being used to replace Potcrate to produce firecrackers.And produce big smog when these materials are seted off, influence visual effect, contaminate environment.
Summary of the invention
Technical problem to be solved by this invention provides a kind of safety, environmental protection and do not have the smokeless propellant of smog when producing and setting off.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of smokeless propellant, and its component and weight percentage are:
Nitro-cotton 30～80% ammoniumper chlorate 20～70%
Adopt the smokeless propellant of technique scheme; owing to adopt nitro-cotton and ammoniumper chlorate when burning, can not produce smog; the present invention is chloracid potassium not; saltpetre; high-risk quick-fried material such as sulphur; improve production process greatly and seted off the security of process; smokelessly launch; smokelessly kick off to show; smokeless bright pearl and smokeless light fireworks; smokelessly; dustless; effectively protected environment; more original old product is gorgeous more colorful; pleasing, be applicable to various high altitude fireworks display projectiles; outfield fireworks such as combined flower, stage fireworks series; toy fireworks series; its powder material can be made various colored captions; pattern firework; torch fireworks etc. are so the present invention is a kind of safety when producing and setting off; environmental protection; there is not smog and easily manufactured; smokeless propellant with low cost.
