The present invention relates to a kind of fireworks and firecrackers composite material and preparation method and applications, the composite material is by carbonate, carrier, metal oxide, adhesive, it is prepared by processes such as mixing, granulation, drying, screenings, the novel environment protection firework firecracker of one kind can be prepared and open quick-fried medicine, widely used sulphur in quick-fried medicine is opened instead of more than one thousand years fireworks and firecrackers, it greatly reduces in production preparation process due to using safety accident caused by sulphur, and eliminate environmental pollution caused by sulfide, preparation process is simple, cheap.
Description
Technical field
The present invention relates to technical field of fireworks and crackers, in particular to a kind of fireworks and firecrackers composite material and preparation method
And application.
Background technique
Fireworks and firecrackers is born in China, and succession brings huge economic benefit so far for China.However, since fireworks are quick-fried
There is accident when bamboo is during making, setting off, and firecracker of setting off fireworks pollutes the environment to a certain extent, pacifies
Complete and environmental protection becomes fireworks and firecrackers industry major issue urgently to be resolved.
Sulphur is widely used in opening in quick-fried medicine for fireworks and firecrackers.The burning point of sulphur is low and thermal sensitivity containing sulphur preparation is high；In preparation, dress
During medicine, sulphur easily accumulates electrostatic, forms electric spark breakdown and opens quick-fried medicine, medicament unexpected burning is caused even to explode.Thus,
Manufacture and assembly open quick-fried cyclome section as process most dangerous in fireworks and firecrackers production.In addition, the combustion product sulfur dioxide of sulphur
It is one of the ingredient of acid rain, causes environmental pollution；Therefore, fireworks can be improved to a certain extent by developing a kind of no sulphur and opening quick-fried medicine
The safety of firecracker production, the adverse effect caused by environment when reducing accident rate, while reducing fireworks firecracker firing.Without sulphur ring
The research and development that guarantor opens quick-fried medicine are of great significance to development, the upgrading of fireworks and firecrackers industry with preparation.
The development of no sulphur pyrotechnic composition is concentrated mainly on the black powder with no sulphur propellant powder substitution sulfur-bearing, and no sulphur opens quick-fried medicine in state
It is rarely reported in inside and outside document.It now, the use of the formula for opening quick-fried medicine is generally potassium hyperchlorate, aluminium powder, sulphur in fireworks and firecrackers
Mixture.Sulfur-free firecracker medicine has been invented by 2014 Nian Yansong China et al.: potassium hyperchlorate, aluminium silver powder, charcoal are composition material, with 55:
43:2 is its quality than component, and because of the selling at exorbitant prices of wherein aluminium silver powder, formula is without economy；Liu Zhongxian in 2016 et al.
Have developed non-sulphur firecracker components, including following components: oxidant, silver powder, titanium-iron powder and/or ferrosilicon powder, wherein oxidant is selected from
Potassium hyperchlorate mixes the composite oxidant or potassium hyperchlorate of composition with barium nitrate, and barium nitrate hygroscopicity is excessively high, the medicament storage phase
Limit is restricted.These medicaments are showed no to be widely used in fireworks and firecrackers enterprise.
Summary of the invention
Based on this, an object of the present invention is to provide a kind of fireworks and firecrackers composite material, and alternative fireworks and firecrackers is opened
Sulphur used in quick-fried medicine, be made it is novel open quick-fried medicine, tradition can be substantially reduced open in quick-fried medicine the production as caused by sulphur and pacify
Full accident, and solve the pollution problem of sulfide produced by sulphur is seted off.
For achieving the above object, specific technical solution is as follows:
A kind of fireworks and firecrackers composite material, including following components: main material, auxiliary material and binder, the main material include carbon
Hydrochlorate and carrier, the auxiliary material are metal oxide；Described adhesive includes organic bond and inorganic bond；
The mass content of the carbonate is 70%~80%, and the mass content of carrier is 20%~25%, metal oxidation
The mass content of object is 0%~5%.
According to an embodiment of the invention, the additional amount of the inorganic bond be the main material and the auxiliary material quality it
The 1%~10% of sum.
According to an embodiment of the invention, the additional amount of the organic bond be the main material and the auxiliary material quality it
The 1%~5% of sum.
According to an embodiment of the invention, the carbonate in calcium carbonate, basic magnesium carbonate and sodium bicarbonate one
Kind, two or three；When using two or three of material blends, mixed proportion is arbitrary proportion mixing.
According to an embodiment of the invention, the carrier is in glass bead, plant fiber, cenosphere and floating bead
It is at least one.
According to an embodiment of the invention, the metal oxide is selected from one of di-iron trioxide, copper oxide or two
Kind.
According to an embodiment of the invention, the organic bond is selected from resin and/or polysaccharide, for example, the resin can
With selected from polyvinyl alcohol resin and/or phenolic resin etc., the polysaccharide can be in dextrin, starch ether and cellulose at least
It is a kind of.
According to an embodiment of the invention, the inorganic bond is sodium metasilicate.
According to an embodiment of the invention, the density of fireworks and firecrackers composite material is 0.8-1.5g/cm3, such as
0.85-1.3g/cm3。
The second object of the present invention is to provide a kind of preparation method of above-mentioned fireworks and firecrackers composite material.
Specific technical solution is as follows:
The preparation method of above-mentioned fireworks and firecrackers composite material, comprising the following steps:
(1) carbonate is uniformly mixed with metal oxide according to said ratio spare；
(2) according to the proportion, adhesive is added into carrier to be uniformly mixed, the mixture that investment step (1) prepares carries out
Granulation, drying, can be obtained the fireworks and firecrackers composite material.
According to an embodiment of the invention, the preparation method further include: screened after drying to particle, obtain qualification
Product, finished product packing.
The third object of the present invention is to provide above-mentioned fireworks and firecrackers composite material to open the application in quick-fried medicine.
In wherein some embodiments, above-mentioned fireworks and firecrackers composite material and other auxiliary materials can further prepare out quick-fried medicine.
It is preferably, based on parts by weight, described that open quick-fried medicine include following components: oxidant (such as perchlorate and/or nitrate；Again
If perchlorate is potassium hyperchlorate, nitrate is barium nitrate) 40~60 parts by weight, metal combustible (such as aluminium powder or magnalium close
Bronze or two kinds of material blends) 15~35 parts by weight, 5~35 parts by weight of composite material.
Compared with prior art, the beneficial effects of the present invention are:
Composite material uses glass bead or plant by mixing preparation, granulation, the technique for drying screening, finished product packing
Fiber or cenosphere or floating bead do carrier, and adhesive is added and is fused together carbonate and metal oxide, solve because
The difference in specific gravity of material, cause simple mixing it is uneven, easily layering the problem of, and play the role of adjusting finished product density, keep it suitable
The use of quick-fried medicine is opened for fireworks and firecrackers.Quick-fried medicine is opened using novel firework firecracker made of composite material, instead of traditional fireworks
Firecracker opens the sulphur in quick-fried medicine, avoids in production preparation process due to using safety accident caused by sulphur, realizes production
Technique improves production security without vulcanization；Reduce the pollution for setting off middle sulphur and sulfide to environment, embodies no sulphur environmental protection
The implementation and popularizing idea of fireworks, and preparation process is simple, it is cheap.
