Abstract
The invention relates to a pyrotechnic composition, and especially relates to a sulfur-free firework propellant. The sulfur-free firework propellant is composed of 60-75 parts of potassium perchlorate, 10-20 parts of charcoal, 10-20 parts of potassium biphthalate and 5-10 parts of resin. Compared with the prior art, the sulfur-free firework propellant has the following advantages that 1)while combusting, the combustion products is potassium chloride, carbon dioxide and water, nitrogen, sulfur and harmful forbidden drugs are not contained, atmosphere pollution is greatly reduced, and environmental protection performance is provided; 2)safety performance can satisfy the national standard requirement; 3)moisture resistance is good, the medicament is stable, long-term (in five years) storage performance is normal; and 4) economy is good, and the popularization and application are easy.
Description
Technical field
The present invention relates to a kind of pyrotechnic composition, especially a kind of firework launching medicine without sulphur type.
Background technology
In actual production at present, firework launching medicine adopts the black powder (military project nitre) being comprised of saltpetre, charcoal and three kinds of materials of sulphur always, it can produce a large amount of smog when burning, affect the firework display effect of fireworks, and in air oxide compound and the residue of residual a large amount of carbon, sulphur, potassium, serious environment pollution.Publication number is that the Chinese invention patent of CN101215211A discloses a kind of " smokeless flameless gunpowder agent ", by auxiliary materials such as nickel hydrazine nitrate and perlite powders, formed, but nickel hydrazine nitrate is a kind of complex primary explosive, improper use easily causes security incident, safety performance does not ensure, production cost higher (approximately 50,000 yuan per ton) simultaneously, is difficult to be suitable for.Or adopt ammoniumper chlorate or the analogue one as oxygenant or oxygenant, but its rate of moisture absorption is higher, and ammoniumper chlorate has deliquescence, limited the application of this series products.
Summary of the invention
The object of the invention is to solve problems of the prior art, provide that a kind of safety and stability, cost are lower, environmental protection without sulphur type firework launching medicine more.
To achieve these goals, the present invention adopts following technical scheme: a kind of without sulphur firework launching medicine, describedly without sulphur firework launching medicine, mainly by potassium perchlorate, charcoal, potassium hydrogen phthalate and resin, formed.Wherein, the parts by weight of each component are potassium perchlorate 60-75 part, charcoal 10-20 part, potassium hydrogen phthalate 10-20 part, resin 5-10 part.
Above-mentioned without in sulphur firework launching medicine, the each constituent materials of the present invention can be buied in firework raw material market or Chemical market according to described title, each component mixes by general method, with alcohol medicine mix wet evenly, with 16 mesh sieve, extrude particle again, put into bright pearl machine and roll out qualified size particles (1.0-2.0mm), be drying to obtain.
The present invention compared with prior art tool has the following advantages: one, products of combustion is Repone K, carbonic acid gas, water when burning, nonnitrogenous, sulphur and harmful forbidden drug, thus can significantly reduce topsoil environmental protection more; Two, safety performance meets national standard requirement; Three, moistureproofness is good, and medicine is stable, and long-term (in 5 years) storge quality is without extremely; Four, good economy performance, applies easily; Ten thousand yuan of the about 1-1.2 of its production cost are per ton, and under equal conditions, its consumption is only equivalent to the 55-65% of military project nitre, can evade in policies and regulations medicine quantitative limitation, and for fireworks, manufacturing enterprise reduces production costs greatly.
