Abstract
A powdered ammonium nitrate explosive is prepared from ammonium nitrate through preparing ammonium nitrate, adding stabilizer to disperse composite fuel oil quickly and safely, and solidifying the oil film at a certain temp to obtain stable and loose superfine ammonium nitrate explosive.
Description
What the present invention relates to is a kind of prescription and the processing method of the powder ammonium nitrate explosive in the civilian fried broken explosive.
Existing powder ammonium nitrate explosive, comprise that explosives such as ammonium oil type, rock type and Permitted Detonator for Coal Mining are to produce both at home and abroad and one of main industrial explosive of using.Because there are problems such as easy moisture absorption caking, package stability is poor, explosive property is not high in powder ammonium nitrate explosive, for many years, done a large amount of research and development work both at home and abroad, CN91107051.6 as Institutes Of Technology Of Nanjing, the CN1053052A of Changsha Mining ﹠ Metallurgy Inst, the blast performance of these two kinds of explosives and package stability are all good, in the powder ammonium nitrate explosive field, obtain than quantum jump with regard to its kind and technical elements.But the former adopts vacuum puffed technological line, still has that plant and equipment change is big, processing conditions is harsh, be unfavorable for large-scale utilization.And the latter adopts technologies such as catalysis, emulsification, sluicing grinding, drying, time, long (producing 200 kilograms in common 60～70 minutes) can not satisfy production requirement in enormous quantities, high efficiency, operation, equipment equally also change greatly, make its practice be subjected to bigger restriction.
The objective of the invention is to: adopt a kind of easy, effective processing method, utilize the existing equipment of factory, satisfy production requirement in enormous quantities, high efficiency, make and a kind ofly do not contain expensive material such as (or containing less) TNT and aluminium, magnesium and the powdered ammonium nitrate-fuel oil explosive new variety of blast performance height, good stability.
Technical scheme of the present invention is: effectively utilize in ammonium nitrate certain temperature range in the powder ammonium nitrate explosive complete processing, its lattice length of side increases and impels the physical property of ammonium nitrate volumetric expansion, by adding ammonium nitrate stabilizer, make the ammonium nitrate fines in certain temperature range, disperse compound fuel quickly and safely, further under the cooling condition even contraction of oil film fixed, under the effect of raising agent, form stable, bulk subparticle powder ammonium nitrate explosive.
Prescription of the present invention and processing step division are as follows:
One, the per-cent of feed composition (%) is: ammonium nitrate 65.0～98.0, ammonium nitrate stabilizer 0.05～0.50, composite fuel oil 1.0～8.0, flammable raising agent 2.0～8.0, tritonal 0～5.0, flame-cooling agent 0～20.0.
In the said components, 1) ammonium nitrate can adopt crystalloid industrial ammonium nitrate or granular agricultural ammonium nitrate; 2) ammonium nitrate stabilizer can adopt single thing or its mixing usefulness such as brown eleostearic acid tri ethanol ammonium salt, 18 triethylenetetraminehexaacetic acids alcohol ammonium salt, 14 alkylbenzene sulfonates, ethylene stearic bicine diester ammonium, 18 alkanamines, Magnesium Stearate, light magnesium oxide powder, ferrosilicon energy, coal dust, activity charcoal powder; 3) adding 0.01～1.0% the oil soluble surfactant that accounts for the oil phase total amount in the mixture that composite fuel oil is made up of a kind of oil fuel or several oil fuel mixes.These oil fuel such as rape oil, tea oil, oleum lini, palm wet goods vegetables oil, as animal oil such as lard, butter, as paraffin wax, heavy oil, Vaseline, go through mineral oil such as green grass or young crops, as polymer combustiblematerialss such as Methyl Hydrogen Polysiloxane Fluid, polyethylene, polypropylene, ethylene oxide, propylene oxides; Its tensio-active agent can be ten dihydroxystearic acids, single stearic acid glycerine lipoprotein, polyoxyethylene pears sugar fatty acid fat, polyethylene oxide alkyl ethers, glycerine three palmitins etc.; 4) flammable raising agent can adopt wood powder, wood charcoal powder, sugared shell powder, bagasse powder or the combustible bulk fines of other polymer; 5) flame-cooling agent is a sodium-chlor.
Two, processing step:
1. the preparation of stablizer and composite fuel oil;
2. hot mixed grind is pressed: with the ammonium nitrate coarse crushing, add at ambient temperature and prepared the stablizer cal rolling and adds the composite fuel oil prepared after 10～20 minutes, be warming up to 85 ℃ ± 5 ℃ and roll discharging after 5～10 minutes;
3. cold mixed grind is pressed: above-mentioned hot mixed grind is extruded the material product, be cooled to 60 ℃～70 ℃ and add a small amount of TNT or do not add TNT, roll and add raising agent after being cooled to 40～50 ℃ again after 5～10 minutes to roll 5～10 minutes be powder type explosive of the present invention.
4. case is rolled up, is packaged into to above-mentioned powder type explosive by mechanical powder charge.
Embodiment 1～3, undertaken as follows by above-mentioned processing step:
One, the preparation of ammonium nitrate stabilizer: 1) get the 18 triethylenetetraminehexaacetic acids alcohol ammonium salt of 50% 18 alkanamines and 50% by weight percentage, stir fusing under 120 ℃ condition, mix, constant temperature stops after 1 hour stirring and placing the room temperature place, obtains solid sheet, block.
2), make 100% promptly to make stablizer in the present invention prescription by 120 eye mesh screens with above-mentioned solid mass 50%, Magnesium Stearate 30%, ferrosilicon powder 20% ground and mixed together.
Two, the preparation of composite fuel oil: get Microcrystalline Wax 70%, polyethylene wax 5%, Methyl Hydrogen Polysiloxane Fluid 0.5%, white paraffin wax 24%, 0.5% 5 kind of material of ten dihydroxystearic acids by weight percentage, under 90 ℃ of conditions melting mixing, stirring promptly makes required composite fuel oil in the present invention's prescription.
Three, the stablizer and the composite fuel oil of above-mentioned preparation are finished three embodiment by prescription described in the technical scheme and processing step, the performance of the proportioning raw materials of each embodiment and the powdered ammonium nitrate-fuel oil explosive of acquisition is respectively as table 1 and table 2.
