Description
Technical field
The present invention relates to a kind of preparation methods of heat-resisting anti-caking ammonium nitrate, belong to energetic material technical field.
Background technique
Ammonium nitrate be it is a kind of be most easy to get to generally the least expensive oxidant.As energetic material, it has oxygen balance height (OB=
+ 20%) advantages such as, burning is smokeless, sensitivity is low.The propellant powder of nitric acid ammonium is with ballistic performance is good, impetus is high, ignition temperature
The features such as low.The propellant of nitric acid ammonium has the characteristics that burning is smokeless, combustion gas characteristic signal is low, low pollution.As in gunpowder
Oxidant, the maximum advantage of ammonium nitrate is exactly to have a safety feature.Its impact sensitivity and friction sensitivity are extremely low, are in pressure
Under 4.35MPa, 90 ° of pivot angles, friction sensitivity explosion percentage is zero, and compression leg load is also reactionless to 36kgf；Feel for hitting
Degree, is dropped hammer, drop height 2m does not also react with 10kg.Gunslinging sensitivity is also extremely low, and cartridge shooting experiment 100% is not reacted.In thermal sensation
In degree test, the 5s bursting point of ammonium nitrate has reached 475 DEG C, higher than 465 DEG C of TNT.So greatly developing low rapid wear at present
Under the background of property ammunition, ammonium nitrate becomes the hot spot of research again.
However, there are also serious defects for ammonium nitrate, such as ignition performance is poor, burning as the oxidant in gunpowder
Speed is low and hygroscopicity is high, its application is caused to be very limited.In general, being about by the propellant burning rate of oxidant of ammonium nitrate
1mm/s, maintaining the minimum pressure of burning is about 5MPa.The thrust that so low burn rate will lead to engine is very low, rocket (or lead
Bullet) flying speed it is low；And the strength of materials that excessively high combustion pressure will lead to combustion chamber must improve, and increase engine
Design difficulty.In addition, ammonium nitrate has strong hygroscopicity, it is highly soluble in water.Its plane of crystal has the thin cavernous structure of crinosity, tool
There are biggish specific surface and residual stress field, this just makes ammonium nitrate have very strong suction-operated to hydrone.So using
When ammonium nitrate, it is necessary to carry out water-proofing treatment to it.
A crucial method for solving ammonium nitrate combustibility difference is exactly by its fine.It is fired after ammonium nitrate fine
Speed can increase considerably, and maintain the pressure of burning that can also significantly reduce.Currently, the method for refinement ammonium nitrate is mainly air-flow crushing
Method.Ammonium nitrate can be crushed to 10 μm or less by air-flow crushing.But the risk of air-flow crushing ammonium nitrate is very high.Ammonium nitrate is in height
It is easy to set off an explosion when striking target plate under the drive of fast air-flow.Moreover, the accumulation of static electricity in Crushing with Jet Mill is also easy
Cause Explosion of Ammonium Nitrate.So comminution by gas stream prepares ultra-fine ammonium nitrate, there is no expanded.In addition, reducing ammonium nitrate moisture absorption
Property method be mainly surface cladding.There are many this kind of report.However, what these researchs were unfolded both for bulky grain ammonium nitrate,
Ultra-fine ammonium nitrate is not exclusively applicable in.And the hygroscopicity of ultra-fine ammonium nitrate is much larger than the ammonium nitrate of bulky grain, it is therefore necessary to adopt
With better anti-moisture absorption method come the phenomenon that preventing ultra-fine ammonium nitrate from agglomerating in air.
Summary of the invention
The technical problems to be solved by the invention: for existing ammonium nitrate ignition performance it is poor, burning speed low and hygroscopicity it is high
The problem of, provide a kind of preparation method of heat-resisting anti-caking ammonium nitrate.
In order to solve the above technical problems, the technical solution adopted by the present invention is that:
(1) according to parts by weight, 30~50 parts of aminomethyl polystyrene resins are weighed respectively, 20~30 parts of isocyanuric acids three shrink
Glyceride, 40~70 parts of methylene chloride, 6~12 parts of triethylamines, 1~10 part of Anhydrous potassium carbonate, by aminomethyl polystyrene resin
It is uniformly mixed with methylene chloride, stands 1~2h, obtain suspension, sequentially add triethylamine and Anhydrous potassium carbonate, stir process obtains
Mixed liquor is added isocyanuric acid three-glycidyl ester and is cooled to room temperature mixed liquor heating water bath reflow treatment, filters to obtain filter
Filter residue is carried out washing and drying treatment, is cooled to room temperature to get covering material by slag；
(2) according to parts by weight, 40~70 parts of ammonium nitrate, 30~50 parts of covering materials, 4~7 parts of deionized waters, 10 are weighed respectively
~20 parts of surfactants, ammonium nitrate and deionized water are uniformly mixed, and obtain compound, are added surfactant, stir process,
Blend is obtained, covering material is added, continues 2~4h of stirring, obtains presoma, presoma is placed in revolving drum granulator at granulation
Reason, obtains heat-resisting anti-caking ammonium nitrate.
Stir process described in step (1) is that low whipping speed is 3~5h of stirring under 60~80r/min at room temperature.
Heating water bath reflow treatment described in step (1) be by mixed liquor at 130~150 DEG C water-bath be heated to reflux 60~
90min。
Washing and drying treatment described in step (1) is successively to be cleaned filter residue 1~2 time with ether and tetrahydrofuran, must be cleaned
Filter residue is dried at being 40~60 DEG C in temperature to constant weight.
Surfactant described in step (2) is neopelex, lauryl sodium sulfate, glycerol monostearate
Any combination in ester, lauryl glucoside.
Stir process described in step (2) is that low whipping speed is 20~40min of stirring under 200~300r/min.
Granulation treatment conditions described in step (2) are as follows: revolving speed be 20~40r/min, vacuum degree be 0.085~
0.098MPa, time are 8~12min, and temperature is 110~130 DEG C.
The present invention is compared with other methods, and advantageous effects are:
(1) present invention is combined as the cladding of ammonium nitrate by aminomethyl polystyrene resin and isocyanuric acid three-glycidyl ester
Material prepares heat-resisting anti-caking ammonium nitrate by vacuum crystallization granulation, and isocyanuric acid three-glycidyl ester is a kind of crystalloid
Heterocyclic epoxy compounds, three epoxy groups are very active, can in polyester resin hydroxyl carry out high density crosslinking.Heterocycle is again very steady
It is fixed, there is excellent heat resistance, weatherability, light resistance, corrosion resistance, chemical resistance and mechanical performance, polystyrene tree
Rouge has good burning performance, inflammable, from burning away after fire, so that the covering material of preparation is heat-resist, and easy firing；Vacuum crystallization
It is the recrystallization process under specified conditions, is crystallized with cooling down and two processes being concentrated, when ammonium nitrate solution enters vacuum knot
After brilliant machine, under vacuum conditions, the decline of solution boiling point carries out spontaneous evaporation using solution potential itself, and improves solution concentration
It is reduced with temperature, then solution enters hypersaturated state, leads to that crystallization is precipitated rapidly, makes solution supersaturated in crystallization process
Degree decline, and with release crystallization heat, and solution evaporation is promoted to carry out, such solution is constantly evaporating, and constantly generates crystallization, most
Full utilization crystallizes thermal evaporation whole moisture and obtains dry ammonium nitrate eventually；
(2) surfactant being added in the present invention has special amphiphilic structure, and when it is acted in solution, solute molecule can
To be arranged in the form of " micella " oriented and orderedly, the surface tension of solution is reduced, when it acts on Crystallization Process can be effectively
Crystallization direction is controlled, can effectively improve the surface characteristic of particle when it acts on particle surface, surfactant is easy to inhale
It is attached on newborn ammonium nitrate crystals surface, significantly reduce caking capacity improves with hygroscopicity.
