Abstract
The invention discloses a smokeless firework propellant. The composition comprises the following ingredients in parts by weight: 30-50 parts of one of guanidine nitrate or nitroguanidine, 20-40 parts of diethylene glycol dinitrate, and 20-40 parts of cellulose nitrate. The smokeless firework propellant has the beneficial effects that smoke occurrence quantity and air residue are small in burning, no smoke is generated through visual inspection; the safety performance meets the national standard requirement; the moisture resistance is good, the medicine is stable, the storage performance has no abnormality for a long time (within five years); the economy is good, and the popularization and application are easy: the production cost is low and slightly higher than the military nitrate, and the increase rate can not exceed 10%; and under same conditions, the using amount accounts for 45-55% of military nitrate.
Description
Technical field
The present invention relates to a kind of pyrotechnic composition, especially a kind of fireworks propelling charge of smoke-less.
Background technology
In the present actual production, the fireworks propelling charge adopts the black powder of being made up of saltpetre, charcoal and three kinds of materials of sulphur (military project nitre) always, it can produce a large amount of black smog when burning, influence the firework display effect of fireworks, and in air the oxide compound and the residue of residual a large amount of charcoal, sulphur, potassium, serious environment pollution.
In the prior art, in order to reduce developing direction of smog is to improve black powder, as Chinese invention patent " no sulphur rocket launching medicine ", Granted publication number is CN1228282C, has removed the sulphur composition in the original compatibility of black powder, makes its cigarette few, but be only applicable to rocket firework, adopt charcoal and saltpetre to make combustible agent and oxygenant, amount of smoke is still bigger, still has a large amount of air residues.
Another improvement direction is to adopt soluble cotton (nitro-cotton, single-base powder), a kind of smokeless fireworks display are disclosed as Chinese utility model patent, its publication number is CN2102493U, its propelling charge is a single soluble cotton or based on the various effect medicines of soluble cotton, though relatively black powder smog will lack, emissivity is not ideal enough.Also have with the soluble cotton be main add ammonium dichromate or perchloric acid by, as publication number is the Chinese invention patent application disclosed " fireworks smokeless propellant " of CN143118lA, with single-base powder is that main raw material adds ammonium dichromate and charcoal composition mixture, but its explosive power is excessive, fried tube appears easily, the cost height.Perhaps adopt a kind of as oxygenant or oxygenant of ammoniumper chlorate or analogue, but its rate of moisture absorption is higher, and ammoniumper chlorate has deliquescence, limited the application of this series products.
Publication number is that the Chinese invention patent of CN101215211A discloses a kind of " smokeless flameless gunpowder agent ", form by auxiliary materials such as nickel hydrazine nitrate and perlite powders, but nickel hydrazine nitrate is a kind of complex primary explosive, improper use easily causes security incident, safety performance does not ensure, simultaneously production cost higher (about 50,000 yuan per ton) is difficult to be suitable for.
Summary of the invention
In order to solve above-mentioned drawback, technical problem to be solved by this invention is that a kind of safety and stability, lower-cost smoke-less fireworks propelling charge composition are provided.In order to solve the problems of the technologies described above, the technical solution used in the present invention is, a kind of smoke less fire cracker propelling charge, it is characterized in that, said composition is made up of following each component, and the ratio of weight and number of each component is: a kind of 30-50 part in Guanidinium nitrate or the nitroguanidine, diethlene glycol dinitrate 20-40 part, nitrocellulose 20-40 part.
In the above-mentioned composition, each constituent materials of the present invention all can be buied in firework raw material market or Chemical market according to described title, and each component mixes by general method, crosses the granulation of 14-18 mesh sieve, is drying to obtain.
Diethlene glycol dinitrate claims diethylene glycol dinitrate again, or claims diethylent glycol dinitrate, English diethylene glycol dinitrate.Being the component of gelatinous explosive and solid propellant, also is the energetic plasticiser of solid propellant.Use mainly as smoke suppressor in this composition, be convenient to the bonding granulation of each component as solvent simultaneously.Guanidinium nitrate or nitroguanidine are as oxygenant, and the little cigarette during burning is eliminated by diethlene glycol dinitrate.The nitrocellulose burning is smokeless.
Preferably, the ratio of weight and number of each component is: in Guanidinium nitrate or the nitroguanidine a kind of 40 parts, 30 parts of diethlene glycol dinitrates, 30 parts in nitrocellulose.
Beneficial effect of the present invention is, one, smog generating capacity and air residue are minimum during burning, and the range estimation non smoke produces; Two, safety performance satisfies the national standard requirement; Three, moistureproofness is good, and medicine is stable, and long-term (in 5 years) storge quality is no abnormal; Four, good economy performance, apply easily: 1. ten thousand yuan of the about 1.3-1.4 of its production cost are per ton, a slightly high military project nitre (1.2 ten thousand yuan are per ton), its amplification can not surpass 10%; 2. under the equal conditions, its consumption only is equivalent to the 45-55% of military project nitre.
The invention will be further described below in conjunction with specific embodiment.
