Abstract

The oxidant of firecrackers comprises 10%-80% of potassium perchlorate, 5%-50% of barium nitrate, 5%-50% of potassium nitrate and 1%-5% of pearlite. Said oxidant is identical to potassium chlorate and pure potassium perchlorate oxidant in effect, and is superior to potassium chlorate oxidant in safety because it adopts the barium nitrate and potassium nitrate with heat-absorbing reaction, at the same time its cost is less than that of pure potassium perchlorate oxidant, so that it has the extensive application.

Description

Firecrackers oxidant

Technical field

The present invention relates to a kind of oxygenant, be meant a kind of oxygenant that is used to produce firecrackers especially.

Background technology

At present, the oxygenant that is used to produce firecrackers on market mainly is with Potcrate, and potassium perchlorate is 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, when mixing bump with sulphur, phosphorus, carbon and organic combustiblematerials, easily takes place to burn and blast.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.

Summary of the invention

The object of the present invention is to provide a kind of safe, lower-cost Firecrackers oxidant.

For achieving the above object, oxygenant of the present invention contains the potassium perchlorate of 10%-80%, the nitrate of baryta of 5%-50%, the saltpetre of 5%-50%, the perlite powder of 1%-5%.

Preferred component of the present invention is the potassium perchlorate that contains 20%-70%, the nitrate of baryta of 10%-40%, the saltpetre of 10%-40%, the perlite powder of 1%-5%.

Another preferred component of the present invention contains the potassium perchlorate of 35%-60%, the nitrate of baryta of 18%-35%, the saltpetre of 18%-35%, the perlite powder of 1%-5%.

Best composition of the present invention contains the potassium perchlorate of 40%-55%, the nitrate of baryta of 24%-30%, the saltpetre of 24%-30%, the perlite powder of 1%-5%.

Main raw material potassium perchlorate of the present invention, nitrate of baryta and saltpetre all are thermo-negative reaction when it decomposes, add and wherein contain perlite powder again, can reduce the susceptibility of these oxygenants, the security that has improved oxygenant greatly, when being used to produce firecrackers, be difficult for taking place security incident.Simultaneously, because oxygenant of the present invention contains the lower nitrate of baryta of a large amount of prices, saltpetre, its cost adopts pure potassium perchlorate low, and price is relatively cheap.

The present invention is further illustrated below in conjunction with specific embodiment.

Embodiment

Embodiment 1:

After 80 kilograms potassium perchlorates, 9 kilograms nitrate of baryta, 9 kilograms saltpetre, 2 kilograms perlite powder fully pulverized mixing, sieve with 100 mesh sieve and to make oxygenant.The detected result that this oxygenant adds the firecrackers of sulphur, silver powder making sees Table 1.

Embodiment 2:

After 70 kilograms potassium perchlorates, 14 kilograms nitrate of baryta, 14 kilograms saltpetre, 2 kilograms perlite powder fully pulverized mixing, sieve with 100 mesh sieve and to make oxygenant.The detected result that this oxygenant adds the firecrackers of sulphur, silver powder making sees Table 1.

Embodiment 3:

After 60 kilograms potassium perchlorates, 19 kilograms nitrate of baryta, 19 kilograms saltpetre, 2 kilograms perlite powder fully pulverized mixing, sieve with 100 mesh sieve and to make oxygenant.The detected result that this oxygenant adds the firecrackers of sulphur, silver powder making sees Table 1.

Embodiment 4:

After 44 kilograms potassium perchlorates, 27 kilograms nitrate of baryta, 27 kilograms saltpetre, 2 kilograms perlite powder fully pulverized mixing, sieve with 100 mesh sieve and to make oxygenant.The detected result that this oxygenant adds the firecrackers of sulphur, silver powder making sees Table 1.

Embodiment 5:

After 18 kilograms potassium perchlorates, 40 kilograms nitrate of baryta, 40 kilograms saltpetre, 2 kilograms perlite powder fully pulverized mixing, sieve with 100 mesh sieve and to make oxygenant.The detected result that this oxygenant adds the firecrackers of sulphur, silver powder making sees Table 1.

Embodiment 6:

After 10 kilograms potassium perchlorates, 44 kilograms nitrate of baryta, 44 kilograms saltpetre, 2 kilograms perlite powder fully pulverized mixing, sieve with 100 mesh sieve and to make oxygenant.The detected result that this oxygenant adds the firecrackers of sulphur, silver powder making sees Table 1.

Firecrackers and firecrackers comparison and detection result such as the table 1 of doing the oxygenant making with Potcrate, pure potassium perchlorate with the oxygenant making of preparing in the foregoing description:

Table 1

From above-mentioned detected result as can be seen, it is feasible replacing Potcrate, pure potassium perchlorate to produce firecrackers with oxygenant of the present invention, and effect can meet the demands substantially, and security is than Potcrate height, and cost is lower than potassium perchlorate again.Potcrate be under an embargo be used to produce fireworks and firecracker after, this oxygenant can be filled up Potcrate fully and forbids producing the great market space that firecrackers stay, and has vast market prospect.
