Abstract
The invention discloses the pyrotechnic composition reducing agent of a kind of safe environment protection type, by rare earth 16～19 parts；220～320 order powdered carbons 55～65 parts；Brilliant carbon dust 19～21 parts；The component compositions such as hydroxypropyl methyl cellulose 7～10 parts.There is the advantages such as security performance is good, environmental-protecting performance is high, processing technology is simple.
Description
Technical field
The present invention relates to the reducing agent of a kind of fireworks pyrotechnic medicine.
Background technology
In fireworks and firecrackers medicament, the effect of reducing agent (also known as combustible) is to provide required heat during medicament burning, different medicaments to heat to need be different.Golf calorific value mostly be metal combustible, lower calorific value mostly be nonmetal can right thing, the activity of combustible and the size of heat is provided, decide the speed of medicament response speed.Reducing agent conventional in present fireworks pyrotechnic medicine has sulfur, Linesless charcoal, aluminium powder, almag etc..With the mixing manufacture firework launching medicine such as potassium nitrate, potassium hyperchlorate, open quick-fried (bud) medicine etc..
But, adopt the pyrotechnic composition that existing reducing agent makes to have the disadvantage that: the big contaminated environment of smog；Safety does not ensure；Complex manufacturing technology, it is necessary to through techniques such as ball milling, oil pressure, polishings.
Summary of the invention
In order to solve above-mentioned drawback, the technical problem to be solved is to provide the pyrotechnic composition reducing agent of a kind of safe environment protection type.In order to solve above-mentioned drawback, the technical solution used in the present invention is, the pyrotechnic composition reducing agent of a kind of safe environment protection type, it is characterised in that described reducing agent is made up of the component of following portions by weight ratio: rare earth 16～19 parts；220～320 order powdered carbons 55～65 parts；Brilliant carbon dust 19～21 parts；Hydroxypropyl methyl cellulose 7～10 parts.
Described rare earth Main Function is in that to improve reaction temperature, it is preferable that cerium or lanthanum；
Described 220～320 order powdered carbon Main Functions are in that to ignite；
Described hydroxypropyl methyl cellulose is called for short: HPMC or MHPC, adopts technical grade HPMC, and Main Function is in that to provide acting energy；
Described brilliant carbon dust belongs to inorganic compound, and outward appearance is white crystal powder body, pH value 7～7.5, Mohs' hardness 9, bulk density 1.68～1.95g/cm3, prior art is applied to diamond tool fixing structure and coated abrasive tool, crystal, the fine abrasive polishing material of electron trade, hot investment casting molding sand, sprayed on material, chemical industry catalyst carrier, mould, decoration, Metal Substrate, the industry such as ceramic matric composite.Rise in the present invention stable passivation meanwhile, it is capable to when with oxidant mixing granulation molding so that particle surface is smooth mellow and full, it is ensured that granule will not surprisingly be ignited, and improves safety.
Above-mentioned each component presses conventional method mix homogeneously, obtains described reducing agent.Reducing agent and potassium nitrate or potassium hyperchlorate proportioning mixing manufacture firework launching medicine, open quick-fried (bud) medicine.Preferably, reducing agent adds potassium hyperchlorate 60 parts or potassium nitrate 65 parts on year-on-year basis, namely can be used as firework launching medicine or open quick-fried medicine.
Preferably, described reducing agent is made up of the component of following portions by weight ratio:
Rare earth 18 parts；220～320 order powdered carbons 60 parts；Brilliant carbon dust 20 parts；Hydroxypropyl methyl cellulose 8 parts.
The beneficial effects of the present invention is, adopt propellant powder that above-mentioned reducing agent makes or open quick-fried medicine, there is following obvious advantage:
1, friction sensitivity, impact sensitivity data are excellent, decrease potential safety hazard to essence；There is enough acting abilities simultaneously, it is ensured that launch and open quick-fried when having taken into account combustion reaction；
2, micro-cigarette, amount of smoke 60～70% is reduced compared with military project nitre, simultaneously pharmaceutical formulation is got rid of sulfur composition completely and is made to eliminate the pollution to environment of sulfur dioxide and sulfide during firework display, without disabling goods and materials (such as plumbous hexachlorobenzene, arsenic compound, mercury compound etc.), environmental-protecting performance is greatly improved；
3, processing technology is simple, the making of reducing agent itself only need to generally mix with, when making propellant powder, without operations such as ball milling, oil pressure, polishings, directly adopt cylinder or rolling disk granulating and forming or adopt crushed screen method granulating and forming, may be used without wet granulation molding, further increase safety.
Following by detailed description of the invention, the present invention will be further described.
