Description
Technical field
The present invention relates to a kind of fireworks safety medicament composition, particularly relate to and a kind ofly make oxygenant with organic bases nitrate or metal oxide, the safety fireworks firecrackers medicament composition that vitriol provides gas expansion, aluminium powder to make combustible agent.
Background technology
In the prior art, for many years, in the preparation of fireworks medicament, extensively adopted Potcrate to do that oxygenant, sulphur are made combustible agent, this class medicament very easily causes spontaneous burning or blast, because of mechanical impact, friction or electrostatic interaction, the security incident that firecracker is produced very easily takes place, and Potcrate is extremely unstable and changeable.In the 19th-century later stage, people recognized the high risk of chloracid potassium medicament gradually, and Britain has banned the pyrotechnic composition of all chloracid potassium and sulphur in 1894, and the U.S. has also banned use of the mixture of Potcrate and sulphur.In October, 2002, the dispatch of China State Council is forbidden to prepare fireworks and firecrackers with Potcrate.
Several factors are to cause the unsettled reason of pyrotechnics composition of chloracid potassium: burning-point that at first is this oxygenant of Potcrate low (356 ℃) and decomposition temperature are low.The decomposition reaction of Potcrate is rare in oxygenant commonly used.Responsive especially during this low melting point of Potcrate and sulphur (119 ℃) fuel mix, their ignition temperature has only 150 ℃.After Potcrate runs into sulphur because sulphur itself may slow oxidation generates sulfuric acid, with the condition of Potcrate coexistence under, this oxidising process more becomes to accelerating, and impels Potcrate to decompose and generates danger bigger chloric acid and dioxide peroxide.So interact, can make Potcrate and sulphur mixture system become extremely unsettled system, be subjected to extraneous bump, friction to produce focus slightly, can excite burning or blast, even may produce spontaneous combustion or self-destruction.
The Tammann temperature of Potcrate is 42 ℃, sees this particularly important from safety point of view, may react under surprising low temperature, particularly contains under sulphur or the organic-fuel situation more likely.Potcrate, saltpetre Tammann temperature are low, are that mysterious accidental ignition reason repeatedly takes place the pyrotechnics composition that contains this class.Use Potcrate, sulphur prescription in the firework medicament at present, impact sensitivity is almost 100%, and friction sensitivity 100% belongs to the high risk gunpowder.Though the firecracker medicament that with Potcrate is oxygenant has good inflammableness, combustibility, helps advantages such as look, the sound, paper breaking rate and economic serviceability, danger and mechanical sensitivity height of its height are fatal characteristics, thereby must improve.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, the not chloracid potassium that a kind of mechanical sensitivity is low, safety performance is high, not sulfureted fireworks medicament composition are provided.
To achieve these goals, technical solution of the present invention: safety fireworks firecrackers medicament composition comprises oxygenant, sulphate cpd, perlite powder, wood charcoal powder and aluminium powder, and the weight proportion of its component is as follows:
100 parts in oxygenant
Sulphate cpd 20-35 part
Aluminium powder 10-40 part
Perlite powder 10-20 part
Wood charcoal powder 3-5 part
Oxygenant is metal oxide or organic bases nitrate, or its their combination;
Metal oxide is ferric oxide, Z 250, cupric oxide, Manganse Dioxide, zinc oxide, cobalt oxide, aluminum oxide, or their arbitrary combination;
Organic bases nitrate is urea nitrate, Guanidinium nitrate, nitroguanidine, or their arbitrary combination;
Sulphate cpd is ferrous sulfate, zinc sulfate, manganous sulfate, vitriolate of tartar, calcium sulfate, copper sulfate, or their arbitrary combination.
The first-selected ferrous sulfate of sulphate cpd.
The preparation method of safety fireworks firecrackers medicament composition is that oxidiser powder is broken to granularity is the 200-400 order, and dry back is standby;
To the processing of sulphate cpd, component difference, method are also different in the preparation method, and existing is that example is described with the ferrous sulfate, and ferrous sulfate is carried out drying treatment; Remove crystal water, its drying temperature is 100-110 ℃, exsiccant ferrous sulfate moisture content is controlled at 0.5-0.2%, be crushed to granularity and put into kneader for the 200-400 order, the superfine light calcium carbonate that adds the 2-4% of the silane coupling agent of 1-3% of ferrous sulfate weight and ferrous sulfate weight then carries out surface treatment, and treatment temp is 80-90 ℃, mediates time 30-40 minute, discharging, sieve, must be with the white ferrous sulfate crystal of sliding property;
Silane coupling agent is vinyl tris silane, R-r-chloropropyl trimethoxyl silane, R-thiopropyl front three chloro silane, R-propyl trimethoxy silicane, vinyltriethoxysilane, or their arbitrary combination;
Safety fireworks firecrackers medicament composition placed to mix in the volume by the weight proportion of component get final product.It is the 200-400 order that its solid particulate is crushed to granularity.
From as can be seen last, oxygenant can be the mixture of wherein any one or two kinds of arbitrary proportions in two compounds of metal oxide or organic bases nitrate, also can be the mixture of the arbitrary proportion of a kind of, several or all kinds in this two compounds.Required oxygen when metal oxide or organic bases nitrate compound provide explosive charge, their decomposition reaction is thermo-negative reaction.Temperature in order to prevent to reduce explosive charge should be with in the sulphate cpd content 20-35 scope wherein.Vitriol is emitted sulfur dioxide gas when decomposition reaction, make explosive produce the gas rapid expansion, improves the firecracker sound.
Sulphate cpd be ferrous sulfate, zinc sulfate, manganous sulfate, copper sulfate, calcium sulfate any, the mixture of the arbitrary proportion of several or all kinds.As adopt a kind of, first-selected ferrous sulfate.
For example ferric oxide is made oxygenant, with reactive aluminum, produces the aluminothermy effect, and the temperature of combustion that can make aluminium is brought up to 2500 ℃ from 1800 ℃, thereby improves quick-fried temperature.The decomposition temperature of ferrous sulfate is 600-700 ℃, and the combustion high temperature of aluminium enough impels ferrous sulfate to decomposite sulfur dioxide gas, and enough gaseous detonations are provided.
Aluminium powder in the composition is a light metal, and temperature can reach about 2000-2500 ℃ during burning, can improve quick-fried temperature to improve the brisance and the sound.
Perlite powder is a weighting agent, is the conditioning agent of medicine density, makes the powder charge thing loose, in order to igniting.
In this implementation process, must add according to described ratio, otherwise have a strong impact on quick-fried property of medicine energy.The add-on of oxygenant must be considered oxygen balance, should provide enough oxygen to impel the oxygen requirement of vitriol, aluminium combustion decomposition; When the content of vitriol low excessively, then the gas volume of Chan Shenging very little, explosion time shredded paper rate variance, paper web may explode not broken: if the too high then gas volume of consumption is too much, the sulphate decomposition caloric receptivity is excessive, has reduced quick-fried temperature and has caused quick-fried tube to explode not open, and reduced the sound.When the aluminium powder consumption is too much,, improved cost simultaneously greatly though can improve quick-fried temperature.The wood charcoal powder that in this prescription, also should add 3-5%, improving the ignition characteristic of quick-fried medicine, but never can be excessive, otherwise the carbonic acid gas that charcoal (C) burning produces is the cooling agent of explosive, obviously reduces quick-fried temperature.Therefore, each composition should add in proportion, and overall equilbrium could guarantee quality product.
The present invention is in preparation process, and its metal oxide does not need to carry out special processing, if can carry out superfine grinding, effect is better, but organic bases nitrate need carry out deep processing.The sulphate cpd first-selection is a ferrous sulfate, and the ferrous sulfate intramolecularly contains 7 crystal water, crystal water must be removed, and promptly dries processing.Exsiccant ferrous sulfate moisture should be controlled at 0.5-0.2%, is crushed to granularity 300-400 order.The superfine light calcium carbonate of the silane coupling agent of the 1%-3% of adding ferrous sulfate weight and the 2-4% of ferrous sulfate weight carries out surface treatment.The adding of lime carbonate is in its objective is and acidic substance.In kneader, mix under the temperature that is incorporated in 80-90 ℃ and handled 30-40 minute at least.The silane coupling agent that uses is the mixture of one or more any component arbitrary proportions of vinyl tris silane, R-r-chloropropyl trimethoxyl silane, R-thiopropyl front three chloro silane, R-propyl trimethoxy silicane and vinyltriethoxysilane.This class material can be expressed as Rsix with general formula
3Wherein X is water-disintegrable functional group, and R is an organo-functional group.Ferrous sulfate makes each particle coat the organic damp-proof membranes of one deck after silane coupling agent is handled, and avoids making in medicine the aluminium powder corrosion, and treated ferrous sulfate has higher activity.In the enforcement, take by weighing each composition weight in proportion, solid particulate is crushed to granularity 200-400 order and sieves, vitriol surface treatment, oven dry, mixing, packing get final product.
Compared with prior art, the present invention has following tangible advantage, (1) owing to adopts ferric oxide to make oxygenant, improved fusing point, fusing point is up to more than 1000 ℃, avoided the low-temperature decomposition shortcoming of Potcrate, the ferrous sulfate decomposition temperature is up to 600-700 ℃ in addition, produces the focus whole medicine accident of blasting of can not igniting and make because of mechanical impact, friction.So it is safe; (2) the firecracker noisemaking rate that adopts medicament composition of the present invention to produce, the sound, coloured light all reach the quality standard of regulation, thereby practical.
