Abstract
The invention discloses a composite oxidant for fireworks and crackers. The composite oxidant consists of the following components in part by weight: 20 to 80 parts of potassium perchlorate, 30 to 100 parts of nitrate, 1 to 2 parts of potassium permanganate and 10 to 20 parts of perlite powder. The composite oxidant is prepared by combining cheap and available oxidants, namely the potassium perchlorate, the nitrate, the potassium permanganate and a flame-retarding antiknock agent which serve as the main components, so that the oxidizability of each component can be fully exerted, and a great amount of new practical properties are generated due to interaction of the components.
Description
Technical field
The present invention relates to a kind of fireworks and firecrackers oxygenant, relate in particular to a kind of composite oxidant for fireworks and crackers.
Background technology
Potcrate is the most frequently used oxygenant in the fireworks and firecrackers life at present, belong to strong oxidizer, its thermal decomposition process is thermopositive reaction, and decomposition temperature is low, inflammableness is good, light the back and be difficult for " cutoff ", " misfire ", explosive good, therefore, better with Potcrate as the firework display effect of the fireworks and firecrackers product of oxygenant, but after adopting Potcrate and sulphur or sulfide composition confection to come into operation, the not only more preceding increase of the incidence of accident, and the also more preceding increase greatly of the destructive force of accident.In order to improve the security in fireworks and firecrackers production, storage and the use, seek the lower fireworks and firecrackers of safety, high energy, price and substitute the Potcrate oxygenant with oxygenant and become the direction that fireworks and firecrackers industry research person pursued and the direction of fireworks and firecrackers industry development.When seeking the substitute of Potcrate, people expect it more being to replace Potcrate with potassium perchlorate, compare with it: the thermostability of potassium perchlorate, fusing point, Tammann temperature and decomposition temperature can improve the safety performance of fireworks medicament all than Potcrate height; Simultaneously, the potassium perchlorate water absorbability is very little, and its stability in storage is good.Though potassium perchlorate also is a strong oxidizer, compares with Potcrate, its chemical property is more relatively stable, the more important thing is when its decomposes, and is the same with the thumping majority oxygenant, needs to absorb heat, to the susceptibility of heat, mechanical sensitivity also less than the Potcrate height.But because the thermal decomposition process of potassium perchlorate is thermo-negative reaction, temperature required during decomposition is higher, oxygen discharging speed is slow, and then relative mistake is a little then only to replace Potcrate to make the fireworks and firecrackers product firework display effect of oxygenant with potassium perchlorate, and cost is also higher.Once also there was the people successfully to develop the not medicinal oxygenant of safe firecracker of chloracid potassium, that is: replace previously used potassium perchlorate with potassium perchlorate and nitrate of baryta, though improved security,, substituted Potcrate fully to such an extent as to can't promote because price is higher.
Summary of the invention
Purpose of the present invention just is to provide that a kind of water absorbability is less, performance, cost, composite oxidant for fireworks and crackers that fireworks effects is superior.
In order to solve the problems of the technologies described above, fireworks and firecrackers composite oxidant provided by the invention is made up of the following component of weight fraction ratio: potassium perchlorate: 20-80 part, nitrate: 30-100 part, potassium permanganate: 1-2 part, perlite powder: 10-20 part.
In technique scheme: described composite oxidant is made up of the following component of weight fraction ratio: potassium perchlorate: 30-70 part, nitrate: 40-80 part, potassium permanganate: 1-2 part, perlite powder: 15-20 part.
Used potassium perchlorate, nitrate, the potassium permanganate of the present invention all is oxygenant cheap and easy to get, with them is the composite oxidant that main component is combined into, their oxidation susceptibilities are separately fully played, and produced the performance of many new reality owing to interact.
1, wherein the nitrate fusing point is lower, and decomposition temperature is lower, can be at first with fireworks and firecrackers in the aluminium powder reaction cause high temperature more than 2000 ℃, the carrying out that causes W-response fast; The effective oxygen-supplying amount of nitrate is higher, can improve the oxygen enrichment value of composite oxidant, improves the combustion speed of gunpowder.
2, add a small amount of potassium permanganate among the present invention, potassium permanganate is comparatively cheap strong oxidizer, potassium permanganate with fireworks and firecrackers in sulphur or the sulfide reaction after discharge Manganse Dioxide, Manganse Dioxide can the catalysis nitrate reaction.
3, in composite oxidant, add potassium perchlorate, can improve the performance of oxygenant, under the situation that has other oxide compounds and nitrate to exist, potassium perchlorate bump and friction to external world had buffered leeway, it is more stable that its performance becomes, potassium perchlorate also has many advantages, and is as the oxygen-supplying amount height, big with sulphur in the fireworks and firecrackers or sulfide reaction thermal value.
4, perlite powder is a kind of burn-proof and explosion prevention agent, and its proportion is less, mix with potassium perchlorate etc. and use the proportion that reduces mixture greatly, and it also has the performance of moisture absorption, reduces the water absorbability of composite oxidant, improves the production efficiency of fireworks and firecrackers.
In technique scheme: described nitrate is saltpetre or SODIUMNITRATE or nitrocalcite or cerous nitrate or nitrate of baryta.
Compared with prior art, the invention has the beneficial effects as follows: the present invention remembers composite oxidant with above-mentioned several components mixing, and preparation technology is simple, the safety performance height, and cost is low, and water absorbability is less.
