Description
Technical field
The present invention relates to a kind of fireworks and firecrackers agglomeration resistance oxidant and preparation method thereof, belong to fireworks and firecrackers manufacture neck
Territory.
Background technology
Since " fireworks and crackers safety and quality " GB10631-2013 implements, because of safety and the stable storing of potassium hyperchlorate
Performance is good, and the oxidant used by present domestic production firecracker is potassium hyperchlorate.But, the production technology of potassium hyperchlorate all uses
The method of potassium chlorate re-electrolysis, often producing one ton of potassium hyperchlorate needs more than 8,000 to spend electricity, consumes substantial amounts of electric energy and potassium resource,
Making the relatively costly of potassium hyperchlorate, price per ton be up to nearly ten thousand yuan, the production cost causing fireworks and firecrackers enterprise is higher.This
Outward, potassium hyperchlorate easily lumps during storing, and increases the production difficulty of fireworks and firecrackers, brings impact to product quality.Cause
This finds and can partly substitute potassium hyperchlorate, has and neither lumps and do not affect usefulness, and lower-cost oxidant, is currently to grind
The emphasis studied carefully and direction.
At present, minority enterprise utilizes the raw materials such as potassium hyperchlorate, potassium nitrate, ammonium nitrate, barium nitrate to be mixed and made into composite oxygen
Agent, lattice combination oxidants etc., some research and development institutions prepare the composite oxidant etc. adding catalyst, but these aoxidize
Agent also exists certain defect at aspects such as setting off performance, storage stability, caking capacity.The reason causing deficiency is probably perchloric acid
Decomposition temperature diversity between potassium and Nitrates is relatively big, can affect and put oxygen speed, and then it is quick-fried to affect fireworks after being mixed
The firework display effect of bamboo.Additionally, after the firecracker product thus planting oxidant production stores a period of time, quick-fried loudness reduces, energy of starting to exchange fire
Power declines, and the rate of burning till does not reaches requirement.The most this kind of composite oxidant can not get the accreditation of enterprise.
Summary of the invention
The defect existed for existing fireworks and firecrackers oxidant, it is an object of the invention to be to provide one to store
Journey prevented from caking, good stability, and can be used for preparing that quick-fried loudness is good, ability of starting to exchange fire strong, burn till rate height, Heat stability is good, moisture absorption
Rate, friction sensitivity, impact sensitivity etc. all can be up to state standards the oxidant of fireworks and firecrackers required.
Further object is that and a kind of method that process is simple, low cost prepares described oxidant is provided.
In order to realize above-mentioned technical purpose, the invention provides a kind of fireworks and firecrackers agglomeration resistance oxidant, this oxidant
Comprise potassium hyperchlorate and barium nitrate oxidation component, and aerosil and tartaric acid and/or Soluble tartar. sodium additives group
Point.
Preferably scheme, potassium hyperchlorate and barium nitrate (1%～40%) by mass percentage in oxidation component: (60%～
99%) composition；It is more preferably by mass percentage (5%～15%): (85%～95%) forms；Most preferably press percent mass
Form than 10%:90%.
Preferably scheme, aerosil be oxidation component quality (potassium hyperchlorate and barium nitrate gross mass) 0.5～
5%, it is more preferably 0.5～2%.
Preferably scheme, tartaric acid and/or sodium potassium tartrate tetrahydrate is oxidation component quality 0.5～5%, is more preferably 0.5
～2%.
Present invention also offers a kind of method preparing described fireworks and firecrackers agglomeration resistance oxidant, the method is by height
Potassium chlorate, barium nitrate, aerosil and tartaric acid and/or sodium potassium tartrate tetrahydrate are placed in pulverizer, pulverize and mix,
It is crushed to mixed material granularity≤400 mesh, to obtain final product.
Preferably scheme, grinding time is more than 15 minutes.
Preferably scheme, in crushing process, addition rose-red is as indicator, is judged as mixing with mixed material color even
Close uniformly.Rosy mass percentage content is not more than 0.01%.
Hinge structure, the technical advantage that technical solution of the present invention is brought:
(1) oxidant of the present invention has and puts that oxygen temperature is low, speed fast, can improve the feature of firework display effect.Conventional
Oxidant such as potassium hyperchlorate decomposition temperature higher than 610 DEG C, and the decomposition temperature of barium nitrate is higher than 590 DEG C, both decomposition temperatures
Diversity is relatively big, can affect and put oxygen speed, thus have impact on the firework display effect of fireworks and firecrackers after being mixed.And the present invention's
By have employed the additive such as sodium potassium tartrate tetrahydrate or tartaric acid in oxidizer formula, can effectively reduce Cl-O and nitre in potassium hyperchlorate
In Barbiturates, the chemical bond energy of N-O, reduces down the decomposition temperature of potassium hyperchlorate and barium nitrate, particularly to Cl-O
Bond energy reduces relatively big, makes potassium hyperchlorate and barium nitrate decomposition temperature difference reduce so that it is to be more suitable for pyrotechnic effect, can improve
Firework display effect.Its effectiveness is may certify that from the relation of gaseous product pressure Yu time.According to the United Nations " about danger
The recommendation test of goods transport and manual of standards " correlation standard, when gaseous product pressure is by 0.69MPa (690 kPas)
Rise to be firecracker white bag charge during 2.07MPa (2070 kPas) required time≤5ms, use oxidant production of the present invention
Firecracker medicine its time after measured is 1.58ms, conformance with standard requirement, it the firecracker quality produced is significantly improved.
(2) oxidant of the present invention can be used for preparing the fireworks and firecrackers that good stability, safety are high.Winestone in oxidant
Soda acid composition in fireworks and firecrackers medicament is played coordination effect by hydrochlorate or sodium potassium tartrate tetrahydrate, acid-base material plays buffering and makees
With.Particularly risen by intermolecular force during medicament smashes process and mechanical mixture and become chemical bond power, carry
The high stability of medicament, it is suppressed that the side reaction of long-term storage, improves storge quality.
(3) the oxidant energy long term storage of the present invention, does not lumps, never degenerates.General Oxidizer Particle Size is the least, for fireworks
During firecracker, effect is the most notable, but oxidizing agent pellets is the least, and its storage process is the most easily lumpd, and is unfavorable for preserving for a long time, easily
Rotten.The oxidizer formula of the present invention, by using aerosil, efficiently solves what oxidant can not preserve for a long time
Problem, on the one hand aerosil can reduce the interaction between granule, add the free-running property between material, significantly subtract
Having lacked the probability of caking, Oxidizer Particle Size≤800 mesh can preserve for a long time, and on the other hand, aerosil can adsorb in time
A small amount of moisture etc., keep oxidant to be dried, improve oxidant storage stability, prevent it from going bad.
(4) oxidant of the present invention can prepare that quick-fried loudness is good, ability of starting to exchange fire is strong, burns till rate height, Heat stability is good, moisture absorption
Rate, friction sensitivity, impact sensitivity etc. all can be up to state standards require fireworks and firecrackers.
(5) the oxidant preparation process of the present invention employs rose-red, can intuitive judgment medicament mixing uniformity.
(6) the oxidant production low cost of the present invention.Oxidant uses cheap barium nitrate primary raw material to replace major part
Expensive potassium hyperchlorate, product per ton can reduce cost about 5000 yuan；Meanwhile, process simplification, produce one ton of basis
The oxidant of invention can economize on electricity 4500 degree, has bigger economic benefits and social benefit.
Detailed description of the invention
It is intended to further illustrate present invention below in conjunction with embodiment, and unrestricted the claims in the present invention protect model
Enclose.
Embodiment 1
