Abstract
The invention discloses a composite oil phase for a powdery ammonium nitrate explosive, which is characterized in that the composite oil phase is prepared from the following raw materials in part by weight: 1,000 to 1,100 parts of compound wax, 500 to 550 parts of Vaseline, 700 to 820 parts of S-80 emulsifier and 240 to 290 parts of lecithin. The composite oil phase overcomes the difficulties of complex production process, huge equipment investment and high production cost in the modification of the surface or interior of ammonium nitrate in the conventional powdery ammonium nitrate explosive, and improves the explosion properties of the explosive by sensitizing and modifying the ammonium nitrate.
Description
Technical field
The present invention relates to a kind of compound oil phase that is used for powder ammonium nitrate explosive.
Background technology
In the an-tnt explosive of forming by ammonium nitrate, TNT and wood powder, because the existence of TNT single chmical compound explosive sensitizing agent makes that the blast performance of this explosive is reliable and stable.But TNT is poisonous, and contaminate environment, so, in recent years, cancellation TNT sensitizing agent in explosive, substitute TNT with oil fuel, produce a kind of powder ammonium nitrate explosive that does not have the TNT sensitization, make to produce nontoxic, this has great importance for improving environmental quality.
But, in the powder ammonium nitrate explosive of forming by ammonium nitrate, oil fuel and wood powder, owing to there is not TNT single chmical compound explosive sensitizing agent, the detonation sensitivity and the blast performance of this explosive are relatively poor, in order to improve the blast performance of explosive, common technology is that ammonium nitrate is carried out modification or autosensibilization etc., can be referring to following patent: Chinese patent CN1144792A, title: the powder ammonium nitrate explosive and the manufacturing process thereof that contain stablizer; Chinese patent CN1220657C, title: a kind of modified and powered ammonium nitrate explosive and manufacture method thereof; Chinese patent CN1569776A, title: ammonium nitrate highly effective dispersing agent; Chinese patent CN91107051.6, title: powder ammonium nitrate explosive and preparation method thereof.Above-mentioned explosive all concentrates on by ammonium nitrate surface or inside are carried out modification, reach the purpose of improving explosion properties, but ammonium nitrate content big (account for explosive total amount 90～92%) in this explosive, big to ammonium nitrate surface or inner complex manufacturing, the facility investment of carrying out modification, the production cost height.
Summary of the invention
The present invention be overcome in the existing powder ammonium nitrate explosive ammonium nitrate surface or inner complex manufacturing, the facility investment of carrying out modification big, the difficult problem that production cost is high provides a kind of ammonium nitrate is carried out the compound oil phase that is used for powder ammonium nitrate explosive that sensitization and modification improve the blast performance of explosive.
For achieving the above object, the concrete technical solution of the present invention is as follows:
Be used for the compound oil phase of powder ammonium nitrate explosive, it is characterized in that: the feedstock production that comprises following weight part forms: 1000～1100 parts of compound wax, 500～550 parts in Vaseline, 700～820 parts of S-80 emulsifying agents, 240～290 parts in Yelkin TTS.
As of the present invention a kind of preferred: be used for the compound oil phase of powder ammonium nitrate explosive, it is characterized in that: the feedstock production that comprises following weight part forms: 1050 parts of compound wax, 540 parts in Vaseline, 780 parts of S-80 emulsifying agents, 250 parts in Yelkin TTS.
The preparation of compound oil phase is made according to a conventional method: with solid-state compound wax under the certain temperature condition fusing after, add vaseline paste and obtain mixture, turn on agitator under normal pressure, slowly add S-80 emulsifying agent, Yelkin TTS in the mixture, mix and stir, thereby make the compound oil phase that is used for powder ammonium nitrate explosive.
A kind of principle that is used for the compound oil phase of powder ammonium nitrate explosive of the present invention is: utilize autoactivation technology and membrane technique, in compound wax, add Vaseline, owing to contain one or more active nitros in the Vaseline molecular structure, and can provide available oxygen, make the compound wax autoactivation, improve the combustion heat of compound wax; Secondly, compound wax, the Vaseline main component is straight-chain paraffin or alkene, branched paraffin or alkene, naphthenic hydrocarbon and aromatic hydrocarbons, belong to non-polar molecule, be insoluble in water, this is the basic reason that is difficult to be dispersed in the powdery ammonium nitrate surface, the condenses of aromatic sulphonate and inferior aldehyde has the characteristics of " amphiphilic " structure, and wetting ability is strong, when acting on compound wax, oleophilic group divides the period of the day from 11 p.m. to 1 a.m, hydrophilic group points to extraneous, when mixing with ammonium nitrate, compound wax is evenly dispersed in the surface of powdery ammonium nitrate granule and forms oil film, has not only increased contact area and combination degree between the two, helps the formation and the acceleration of explosive reaction, and may seal the formation micro-bubble, be beneficial to emerging of " focus "; When explosive was excited, oil fuel flowed in ammonium nitrate granule surface viscous, produces the relative movement of utmost point intensive, has improved the possibility that forms " focus " in the part, thereby has improved the blast performance of ammonium nitrate dynamite.
