Abstract
The invention discloses a safe and environment-friendly pyrotechnic composition reducing agent. The safe and environment-friendly pyrotechnic composition reducing agent is prepared from the following components: 16 to 19 parts of rare earth, 55 to 65 parts of powdered carbon of 220 to 320 meshes, 19 to 21 parts of powdered amorphous carbon, and 7 to 10 parts of hydroxypropyl methyl cellulose. The safe and environment-friendly pyrotechnic composition reducing agent has the advantages of being high in safety, high in environmental protection, and simple in preparation process.
Description
Technical field
The present invention relates to a kind of reductive agent of fireworks pyrotechnic medicine.
Background technology
Required heat when the effect of reductive agent (also known as combustiblematerials) is to provide medicament burning in fireworks and firecrackers medicament, different medicaments to heat to need be different.Golf calorific value mostly be metal combustiblematerials, lower calorific value mostly be nonmetal can right thing, the activity of combustiblematerials and provide the size of heat, decides the speed of medicament speed of response.Reductive agent conventional in present fireworks pyrotechnic medicine has sulphur, charcoal, aluminium powder, aluminum magnesium alloy etc.With the mixing manufacture such as saltpetre, potassium perchlorate firework launching medicine, open quick-fried (bud) medicine etc.
But the defect of the pyrotechnic composition adopting existing reductive agent to make is: the large contaminate environment of smog; Security does not ensure; Complex manufacturing technology, needs through techniques such as ball milling, oil pressure, polishings.
Summary of the invention
In order to solve above-mentioned drawback, technical problem to be solved by this invention is, provides a kind of pyrotechnic composition reductive agent of safe environment protection type.In order to solve above-mentioned drawback, the technical solution used in the present invention is, a kind of pyrotechnic composition reductive agent of safe environment protection type, is characterized in that, described reductive 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; Vltra tears 7 ~ 10 parts.
Described rare earth Main Function is to improve temperature of reaction, preferred cerium or lanthanum;
Described 220 ~ 320 order powdered carbon Main Functions are to ignite;
Described Vltra tears is called for short: HPMC or MHPC, and adopt technical grade HPMC, Main Function is to provide acting energy;
Described brilliant carbon dust belongs to mineral compound, and outward appearance is white crystal powder, pH value 7 ~ 7.5, Mohs' hardness 9, tap density 1.68 ~ 1.95g/cm
3, be applied to diamond tool fixing structure and coated abrasive tool, crystal, the fine abrasive polishing material of electron trade, precision casting molding sand, spray material, chemical industry catalyst carrier, mould in prior art, decoration, metal matrix, the industries such as ceramic matric composite.While playing stable passivation in the present invention, can, when shaping with oxygenant mixing granulation, make particle surface smooth mellow and full, guarantee that particle can not surprisingly be ignited, improve security.
Above-mentioned each component mixes by general method, obtains described reductive agent.Reductive agent and saltpetre or potassium perchlorate proportioning mixing manufacture firework launching medicine, open quick-fried (bud) medicine.Preferably, in reductive agent, add potassium perchlorate 60 parts or 65 parts, saltpetre on year-on-year basis, namely can be used as firework launching medicine or open quick-fried medicine.
Preferably, described reductive 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; Vltra tears 8 parts.
Beneficial effect of the present invention is, the propelling charge adopting above-mentioned reductive agent to make or open quick-fried medicine, has following obvious advantage:
1, friction sensitivity, impact sensitivity data excellence, decrease potential safety hazard to essence; There is when having taken into account combustion reactions enough acting abilities simultaneously, guarantee launch and open quick-fried;
2, micro-cigarette, amount of smoke 60 ~ 70% is reduced compared with military project nitre, simultaneously formula of medicine is got rid of sulphur composition completely and is made to eliminate during firework display sulfurous gas and sulfide to the pollution of environment, not containing forbidding goods and materials (as plumbous hexachlorobenzene, arsenic compound, mercury compound etc.), environmental-protecting performance improves greatly;
3, manufacture craft is simple, the making of reductive agent itself only need generally mix, when making propelling charge, without the need to operations such as ball milling, oil pressure, polishings, direct employing cylinder or rolling disk granulating and forming or adopt crushed screen method granulating and forming, also wet granulation can be adopted shaping, further increase security.
Below will the present invention will be further described by embodiment.
