Description
Technical field
The present invention relates to a kind of compound oil phase that contains Nitromethane 99Min. 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 by oil fuel (account for explosive total amount 4～6%) being carried out the compound oil phase that is used for powder ammonium nitrate explosive that sensitization and modification improve the blast performance of explosive.
Concrete technical solution is as follows:
The compound oil phase that is used for powder ammonium nitrate explosive comprises the raw material of following weight part:
Solid fuel oil 72-92,
Liquid fuel oil 5.0-20,
Nitromethane 99Min. 2.0-5.0,
The condenses 1.0-3.0 of aromatic sulphonate and inferior aldehyde;
Described solid fuel oil is paraffin and/or pitch and/or rosin;
Described liquid fuel oil is machine oil and/or diesel oil and/or silicone oil and/or heavy oil;
Described Nitromethane 99Min. is mononitromethane and/or dinitromethane and/or trinitromethane;
The condenses of described aromatic sulphonate and inferior aldehyde is β naphthalene sulfonate salt and formaldehyde condensation products, or β naphthene sulfonic acid calcium salt and formaldehyde condensation products, or β naphthene sulfonic acid magnesium salts and formaldehyde condensation products, or β naphthene sulfonic acid calcium salt and acetaldehyde condensation thing, or β naphthalene sulfonate salt and acetaldehyde condensation thing, or β naphthene sulfonic acid magnesium salts and acetaldehyde condensation thing.
A. with solid fuel oil after fusing under the temperature 75-95 ℃ condition, add the liquid fuel oil consolute, the oil fuel mixture;
B. turn on agitator under normal pressure adds the condenses of aromatic sulphonate and inferior aldehyde in the oil fuel mixture slowly, mixes 5-10 minute, temperature 75-95 ℃, forms the modification oil phase;
C. Nitromethane 99Min. is added in the modification oil phase slowly, mixed 5-10 minute, temperature 75-95 ℃, make the compound oil phase that contains Nitromethane 99Min..
A kind of principle that contains the compound oil phase of Nitromethane 99Min. of the present invention is: utilize autoactivation technology and membrane technique, in oil fuel, add Nitromethane 99Min., owing to contain one or more active nitros in the Nitromethane 99Min. molecular structure, and can provide available oxygen, make the oil fuel autoactivation, improve the combustion heat of oil fuel; Secondly, solid fuel oil and liquid fuel oil main component are 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 oil fuel, 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, oil fuel 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.
The present invention compared with prior art, its significant advantage is:
1, the preparation of the compound oil phase of adding Nitromethane 99Min. sensitization is domestic in the relevant powder ammonium nitrate explosive does not still have report, owing to contain one or more active nitryl groups in the Nitromethane 99Min., has improved the detonation sensitivity of powder ammonium nitrate explosive.
2, both contain activated oxidisability group in the Nitromethane 99Min., contained flammable group again, and meltable in oil fuel, further strengthened the incendiary effect of oil fuel.
3, among the present invention the condenses of solid fuel oil and liquid fuel oil and aromatic sulphonate and inferior aldehyde is combined, utilize the hydrophobic effect of solid fuel oil and liquid fuel oil, utilize the surfactivity and the scattering and permeating effect of the condenses of aromatic sulphonate and inferior aldehyde, thereby played the anti-water of powdery ammonium nitrate and the double effects of modification, the package stability of explosive significantly improves.The combustion heat value height of the compound oil phase of the present invention on the other hand, viscosity is little, is easy to be dispersed in powdery ammonium nitrate granule surface, forms moistureproof, anti-caking and water resisting oil film.
4, further improved the explosion energy of powder ammonium nitrate explosive, as made powder ammonium nitrate explosive, the explosion energy of prior art products is 3286KJKg
-1The explosion energy of product of the present invention is 3659KJKg
-1, thereby have higher capacity for work.
5, the compound oil phase manufacturing process of powder ammonium nitrate explosive of the present invention is simple, reliable, cost is low, is convenient to suitability for industrialized production and application.
