Abstract
The invention discloses a micro smoke ignition agent for fireworks, which consists of potassium perchlorate, carbon powder, nitro-cotton and/or nitroguanidine, a high-energy reducing agent and a detonation agent. The invention has the advantages that: an oxidant adopts a high-oxygen content and high-stability substance, so that the using amount can be controlled and smoke can be reduced; combustibles can release a large amount of heat during combustion, so that a high-temperature substance is generated; therefore, the using amount can be controlled and the smoke can be reduced; and main combustibles adopt high-oxygen content substances, so that the using amount of smoke oxidants can be reduced to the greatest extent. Therefore, only micro smoke is generated during combustion of the ignition agent. Due to the detection result of light transmittance, compared with that of the conventional same-class corresponding products, the produced smoke is reduced by 70 percent. Meanwhile, the configuration of the whole medicament system guarantees ignition performance and stability of the ignition agent, and the safety performance meets the requirement of the national standard.
Description
Technical field
The present invention relates to a kind of pyrotechnic composition compsn, particularly a kind of fireworks are with little smoke point powder composition.
Background technology
Fireworks have a drug effect fruit part with what ignition powder was used for firework bright bead, powder column and generation handle, wandering star and other moulding, himself are lighted afterfire by propelling charge or blasting powders, remove to light the higher effect medicament of point of ignition again.In the prior art, fireworks all are with the different black powder of various proportionings with ignition powder or black powder adds potassium perchlorate and aluminium-magnesium alloy powder is processed.The amount of smoke that its burning produces is very big.Have a strong impact on the igniting fireworks effect, cause environmental pollution.
Summary of the invention
In order to overcome above-mentioned drawback, technical problem to be solved by this invention is, has only little cigarette after a kind of setting off is provided, and can keep the ignition characteristic of its original priming charge and little smoke point gunpowder of stability.
In order to solve the problems of the technologies described above, the technical scheme that the present invention adopted is that a kind of fireworks are made up of potassium perchlorate, powdered carbon, nitro-cotton and/or nitroguanidine, high energy reductive agent, the medicament that detonates with little smoke point powder composition:
Said high energy reductive agent adopted the high hot combustiblematerials powder of 100-500 mesh standard sieve, was any one or any multiple arbitrary proportion mixture in zirconium, titanium, aluminium, aluminum magnesium alloy, titanium hydride, zircoium hydride, the calcium silicide powder; The said medicament that detonates adopts any one in lead azoimide, the nickel hydrazine nitrate.
Said each component mixes, in order to avoid medicine is because of the layering of density difference.Whole medicine has all been starched drying with starch solution and has been ground, so that increase ignition characteristic.
As a kind of preferred, described fireworks use the ratio of weight and number of little smoke point powder composition to be: nitro-cotton and/or nitroguanidine 30-90 part, potassium perchlorate 5-15 part, powdered carbon 5-10 part, high energy reductive agent 3-15 part, the medicament 1-5 part of detonating.
Said potassium perchlorate is as oxygenant, and is because of its oxygen level is high, though it can produce smog in combustion processes, because amount is few, little to the cigarette amount influence of whole little cigarette medicament.
Said nitro-cotton and nitroguanidine can materials for smokelessly containing, and can use separately or make up and use as the burning main body, can make medicament little cigarette that burns; It is the single, double original washing powder of staple that the present firework industry of nitro-cotton adopts nitro-cotton mostly, is processed through operations such as fragmentation, interpolation tranquilizers by military retired single-base powder or double-base powder, and it is cheap, is suitable for low-cost firework medicament.
Said high energy reductive agent all can be emitted big calorimetric when burning, thereby produces high temperature, so that light high burning-point medicine.Their consumptions are all very little, so can not produce a lot of smog.Said powdered carbon, especially waste of flax powdered carbon, point of ignition is low, is convenient to lighted.Both make up use can effectively improve the medicine ignition characteristic.
To combine embodiment that the present invention is described further below.
Embodiment
Embodiment 1: the preparation process of said little smoke point powder composition is following:
1, high energy reductive agent-aluminium-magnesium alloy powder is crossed 200 mesh standard sieves;
2, by ratio of weight and the number of copies, get 78 parts of single, double original washing powders, 10 parts of potassium perchlorates, 5 parts of waste of flax powdered carbons, 5 parts of aluminium-magnesium alloy powders, 2 parts of lead azoimide, said medicine adopt the method for repeatedly sieving fast to mix, and starchs, drying, grind with starch solution again.Promptly accomplish the preparation of said little smoke point powder composition.Each constituent materials of the present invention all can be buied in firework raw material market or Chemical market according to said title.
Embodiment 2: be that with embodiment 1 difference the component of said little smoke point powder composition and ratio of weight and number are: 27 parts of single, double original washing powders, 40 parts of nitroguanidines, 15 parts of potassium perchlorates, 10 parts of pine powdered carbons, 10 parts of titanium hydrides, 3 parts of nickel hydrazine nitrates.
Embodiment 3: be that with embodiment 1 difference the component of said little smoke point powder composition and ratio of weight and number are: 35 parts of single, double original washing powders, 5 parts of potassium perchlorates, 7 parts of China fir powdered carbons, 3 parts of metallic aluminium powders, 1 part of nickel hydrazine nitrate.
Embodiment 4: be that with embodiment 1 difference the component of said little smoke point powder composition and ratio of weight and number are: 30 parts of nitroguanidines, 8 parts of potassium perchlorates, 6 parts of waste of flax powdered carbons, 7 parts of calcium silicides, 3 parts of lead azoimide.
Embodiment 5: be that with embodiment 1 difference the component of said little smoke point powder composition and ratio of weight and number are: 45 parts of single, double original washing powders, 12 parts of potassium perchlorates, 8 parts of waste of flax powdered carbons, 9 parts of metallic titanium powder, 5 parts of lead azoimide.
