Abstract

The present invention discloses a porous mixed ammonium nitrate explosive which is prepared by combining porous ammonium nitrate and a high-oil powdery emulsion explosive. The present invention is composed of 10 to 50 wt% of porous ammonium nitrate and 50 to 90 wt% of high-oil powdery emulsion explosive. The porous mixed ammonium nitrate explosive of the present invention has the characteristics of simple production process and high producing energy, and the water-resisting properties and the high detonation velocity of the powdery emulsion explosive are kept. Detonation performance is better than that of a porous granular ammonium nitrate explosive, and cost is lower than that of a powdery emulsion explosive. The present invention can be used for surface blasting, can also be used for small-bore blasting, and can be used in wet blast holes.

Description

Porous mixed ammonium nitrate explosive
Technical field
The present invention relates to a kind of industrial ammonium nitrate pyrotechnic composition, particularly relate to the porous mixed ammonium nitrate explosive that the quick-fried industry of the people is used.
Background technology
The explosive that the quick-fried industry of the people is used mainly contains ammonium nitrate-fuel oil mixture, emulsion explosive, an-tnt explosive.The an-tnt explosive blast performance is better, but toxic substance is harmful, and the cost height.Porous grain ammonium nitrate-fuel oil mixture is a kind of industrial explosive that is widely used in the surface mine explosion, because it is with low cost, production technique is simple, favored by the user.But it also exist not anti-water, explosion velocity low, do not fit into weak points such as aperture explosion and hard rock blasting.
Powdery emulsifying explosive is a kind of high performance industrial explosive, and certain water resisting property is arranged, and applicable to the various engineering explosion, but powdery emulsifying explosive exists production cost height, the limited deficiency of throughput.
Summary of the invention
Purpose of the present invention is exactly at the above-mentioned problems in the prior art, a kind of production technique is simple, detonation property is better than the porous and granular ammoniumnitrate explosives and provide, cost is lower than powdery emulsifying explosive, applicable to the porous mixed ammonium nitrate explosive of various engineering blasting operation condition.
For realizing the present invention's purpose, porous mixed ammonium nitrate explosive of the present invention is achieved through the following technical solutions.
Porous mixed ammonium nitrate explosive of the present invention is to be constituted by porous grain ammonium nitrate, high oil-bound distemper shape emulsion explosive, and the each component content range is:
Porous grain ammonium nitrate 10%~50% (weight);
High oil-bound distemper shape emulsion explosive 50%~90% (weight).
The component concentration (weight) of described high oil-bound distemper shape emulsion explosive is: organic oil phase material 4.5%~8.7%, emulsifying agent 1.2%~2.2%, water 1.8~3.5%, ammonium nitrate 88%~92.5%.
Described organic oil phase material is: 2~5 kinds of mixtures in stearic acid, slack wax, mixed crystal wax, paraffin, Microcrystalline Wax, the rosin.
Described emulsifying agent is a polyisobutene succinimide family macromolecule emulsifying agent.
Principle of the present invention is: porous grain ammonium nitrate is a kind of oxygenant, and oxygen balance is 0.2, mixes with normal powdery emulsifying explosive, and it is unnecessary oxygen supply to occur in the explosive, the combustible agent deficiency.In order to guarantee that explosive charge reacts completely, oxygen balance will be near zero, so the suitable oil phase ratio that improves when producing powdery emulsifying explosive guarantees that enough flammable compositions are the main points of this porous mixed ammonium nitrate explosive of preparation.
The present invention compares with existing explosive, and its distinguishing feature is:
1. pyrotechnic composition have kept the characteristics of powdery emulsifying explosive water resisting property, high explosion velocity.Compare with powdery emulsifying explosive, cost has reduced by 15%; Compare with porous grain ammonium nitrate-fuel oil mixture, detonation property and water resisting property improve greatly; Compare with industrial powdered an-tnt explosive, do not contain tritonal, the detonation index is higher than industrial powdered an-tnt explosive, and cost also is lower than industrial powdered an-tnt explosive.
2. enlarge the scope of application, not only can be used for surface blasting but also can be used for the small-bore explosion, in moist big gun hole, used, also had blasting effect preferably.
3. production technique is simple, and quality product guarantees easily, for the producer that powder emulsified production line is arranged, only needs investment seldom.
4. can significantly improve the explosive production capacity, throughput has improved 80%, rate of return on investment height, remarkable in economical benefits.
