Abstract
The present invention relates to a TNT-free rock powdery ammonium nitrate explosive and a preparation method thereof. The present invention belongs to an explosive and a preparation method thereof, which particularly relates to a TNT-free powdery ammonium nitrate explosive and a preparation method thereof. The TNT-free rock powdery ammonium nitrate explosive of the present invention is formed by preparing 3% to 5% of wood powder, 2% to 4% of compound oil phase and ammonium nitrate as the rest. In addition, a modifying agent of which the weight is 0.3% to 0.5% of that of the TNT-free rock powdery ammonium nitrate explosive is also added. When the present invention is prepared, the ammonium nitrate is modified firstly, and is mixed with various materials after being added into an airflow line to be pulverized and dried. Compared with the production of the traditional powdery ammonium antimony explosive, the present invention has the advantages that technology is simple, the hazard of trinitrotoluene to human bodies and environment is avoided, components of the TNT-free rock powdery ammonium nitrate explosive are uniformly mixed, ammonium nitrate is milled and exquisite, manufacturing environment is improved, automatic production is easy to realize, product costs are lowered, quality is ensured, and product explosive power is large.
Description
Technical field
The invention belongs to extremely preparation method of a kind of explosive, refer specifically to powder type explosive that does not contain by tritonal and preparation method thereof.
Technical background
At present in China's powder type explosive, contain terraced explosive and account for about 50% of total amount, though this class powdery ammonium ladder detonator power is higher, raw material extensively, is easily produced and compare safety, but tritonal is a kind of nitro-compound, physiological function to human body seriously influences, the personnel of long-term contact understand chronic poisoning, therefore contain the ratio of terraced explosive in industrial explosive and reduce just year by year.Because the main component ammonium nitrate of explosive has stronger moisture absorption and anti-caking, satisfy the big main points of three in the Operating Condition of Powder Explosive Production " dried, thin, even ", in industry generally believe and adopt the air-flow production technique can not produce qualified TNT-free powdered nitramon, so still adopting the rolling disintegrating process that falls behind to produce an-tnt explosive.This just is difficult to realize serialization, the automatic production of non-TNT powder explosive.
Summary of the invention
Technical problem to be solved by this invention provides a kind of air-flow production technique and corresponding special-purpose no terraced properties-correcting agent thereof of TNT-free powdered nitramon, technology of the present invention is simple, compare with the production of conventional powdered an-tnt explosive, avoided tritonal human body and environmental hazard.Each component of explosive mixes, and ammonium nitrate is pulverized fine and smooth, and production environment improves, and easily realizes automatic production, reduces product cost, ensures the quality of products, and the product brisance is big.
Solving technical problem of the present invention adopts the explosive weight percentages of components to be: wood powder 3%～5%, compound oil phase 2%～4%, surplus are ammonium nitrate, in above-mentioned explosive component, also add the properties-correcting agent of its weight 0.3%～0.5% in addition, wherein compound oil phase is diesel oil, machine oil, paraffin, compound wax and stearic mixture, comprises sodium methylene bis-naphthalene sulfonate, stearic acid, octadecyl acetate, alkylbenzene sulfonate and wilkinite in the properties-correcting agent.
The weight percent of each component of compound oil phase is in the above-mentioned prescription, diesel oil 30%, machine oil 30%, paraffin 16%, compound wax 16%, stearic acid 8%; The weight percent of each component is in the properties-correcting agent, sodium methylene bis-naphthalene sulfonate 10%, stearic acid 5%, octadecyl acetate 40%, alkylbenzene sulfonate 30% and wilkinite 15%.
The air-flow production technique of using above prescription is: add raw material ammonium nitrate, wood powder, compound oil phase in airflow line in proportion; Ammonium nitrate is before entering airflow line, at first add properties-correcting agent and carry out modification, then the ammonium nitrate after the modification is imported pulverizing, drying in the airflow line by quantitative, and in the air-flow mixing duct, add wood powder, compound oil phase simultaneously, after cyclonic separation, obtain TNT-free explosive; By the medicine of a cold nature device medicine of a cold nature, powder charge again below the medicine temperature drop to 45 ℃, packing.
In this technology, the temperature of material in airflow line should be controlled to be 105 ℃～125 ℃, and multiple spot adding in airflow line is adopted in the adding of compound oil phase.
Technique scheme of the present invention can reach following effect:
(1) operating environment improves.Owing to do not contain tritonal in the explosive component of the present invention, and pulverize that to mix be to carry out in the pipeline of sealing, no dust is overflowed, and the health of having eliminated operator endangers, and has avoided common frequently-occurring occupational illness.
(2) each component mixes, and ammonium nitrate is pulverized fine and smooth.Material is except that being subjected to the pulverizing of equipment inherent, do at air-flow under the mixing effect of propellant, the ammonium nitrate saturated solution becomes the viscosity material dispersed, the ammonium nitrate fineness is improved, powder content increases, air-flow plays secondary and pulverizes and mixing effect, and controls the ammonium nitrate moisture content easily, and compound oil phase adopts the multiple spot adding to avoid material to glue wall.
(3) easily realize automatic production.Adopt chimneying production to help realizing centralized management and automatization control.
(4) product cost is low.Low 16.5 yuan per ton than powdery ammonium ladder detonator of manufacturing costs, low 22.5 yuan per ton than expanded explosive, direct material cost is per ton than low 110 yuan of powdery ammonium ladder detonator, than low 2.2 yuan of expanded explosive.
