Description
Technical field
The present invention relates to the granular ammonium nitrate-fuel oil mixture of a kind of viscosity and preparation method, belong to commercial explosive preparing technical field.
Background technology
In order to adapt to the needs of shallow bore hole or deep hole charge pneumatic machinery, alleviate powder charge labour intensity, reduce and return dose, improveBlast hole utilizing factor, people have developed terraced glutinous pellet explosive. This explosive is exploded by ammonium nitrate, diesel oil and thicknessAgent mixes, and existing certain fluidity has again suitable adherence, has substantially solved charge pneumatic machinery process and has returned asking of medicineTopic. But owing to containing 1/3 TNT in added thickness burster, in producing and using, unavoidably workman is caused to dangerEvil. For addressing this problem, 85100393), " novel sticky without ladder Chinese patent literature " viscous granular Non-TNT explosive " (application number:Property explosive and manufacture method thereof " 89107503.8), " a kind of ammonium nitrate-fuel oil mixture " (application number: 201210225182.3) (application number:Deng disclose separately without terraced viscous explosive formula and preparation method, its theme thinking is all taking nontoxic methylamine nitrate as quickAgent substitutes the TNT that toxicity is larger, but methylamine nitrate is extremely responsive as a kind of single chmical compound explosive, production process complexity, workSkill control is had relatively high expectations, do not meet on-site mixed explosive sensitivity low, produce simple requirement, produce and use procedure in the middle of depositIn great potential safety hazard. In patent documentation 89107503.8, add aluminium powder, sulphur to bringing larger powder in the middle of productionDirt and blast, danger of combustion, and in explosion product, contain more sulfur dioxide pollution air. Chinese patent literature (ShenPlease number: 200610010603.5) disclose a kind of glutinous pellet explosive, cancelled the responsive single chmical compound explosive such as TNT, methylamine nitrateUse, greatly reduce blast, danger of combustion characteristic in production process, but still used calcium carbonate, talcum powder, double glazingMicroballoons etc. easily generate the component of a large amount of dust, and in the solid powder adding, 30% for the very little hollow glass microballoon of density, offsetThe density of bringing after calcium carbonate, talcum powder add increases, limited on degree of packing impact. Solid meal component is inhaled in explosive reactionReceived a large amount of heats, the gas of generation is limited, and quick-fried heat is had a certain impact.
At present along with the development of the high sensitization of emulsion, high temperature Charge and popular, domestic Emulsion Explosive Production producerThe overwhelming majority has adopted heat-sensitized technology, and heat-sensitized technology is bringing large production capacity, high efficiency while also to produce greatlyThe useless medicine of emulsification and the matrix of amount, Emulsion Explosive Production security incident took place frequently due to 2013 to 2014, responsible departments of the government fromSecurity standpoint is considered to have forbidden the useless medicine producing in stub bar, material tail and debug process is joined to feed bin processing before powder charge, givesCurrent useless medicine processing brings certain difficulty.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of component simple, security is good, detonates reliable, production processThe granular ammonium nitrate-fuel oil mixture of easier viscosity and preparation method.
Technical scheme of the present invention is as follows:

According to the present invention, preferred, the granular ammonium nitrate-fuel oil mixture of described viscosity, raw material components is as follows, is weight portion:
According to the present invention, preferred, the granular ammonium nitrate-fuel oil mixture of described viscosity, raw material components is as follows, is weight portion:
According to the present invention, preferred, the particle diameter of described powdered polypropylene acid amides is 0.1～1mm;
Preferably, described gluey polyacrylamide is for by polyacrylamide: water=1:(7～12) mass ratio is mixed to getArrive, preferred, polyacrylamide: the mass ratio of water is 1:9.
According to the present invention, the preparation method of the granular ammonium nitrate-fuel oil mixture of above-mentioned viscosity, step is as follows:
(1) in blender, add ammonium nitrate by above-mentioned weight portion, then spray into diesel oil, mix;
(2) add powdered polypropylene acid amides and waste emulsion explosive or process of dynamite substrate, continue to stir 3～5 minutes;
(3) add gluey polyacrylamide, continue to stir 3～5 minutes, to obtain final product.
Ammonium nitrate and diesel oil are mixed to get ammonium nitrate-fuel oil mixture by the present invention, with waste emulsion explosive or emulsion baseMatter is coated ammonium nitrate-fuel oil mixture, can improve water repelling property and sensitivity to initiation; Waste emulsion explosive or process of dynamite substrate are filled into ammonium oilIn the space of explosive, can improve effective charge density. The present invention, by first add water in polyacrylamide, prepares gluey polypropyleneAcyl ammonium, has avoided water to contact with the direct of explosive component, is first coated nitre with waste emulsion explosive or the process of dynamite substrate of water resistantAcid ammonium, then adds moisture gluey PAM, makes explosive component and moisture gluey PAM isolation, is conducive to guaranteeProduct sensitivity to initiation and shelf-life. Add powdered polypropylene acid amides can make viscosity the best of product.
Beneficial effect of the present invention:
1, the granular ammonium nitrate-fuel oil mixture of viscosity of the present invention is without dust, and without single chmical compound explosive, without cap-sensitivity, sensitivity to initiation is moderate,Available common emulsion and bulking ammonium nitrate explosive detonate.
2, the granular ammonium nitrate-fuel oil mixture water repelling property of viscosity of the present invention and sensitivity to initiation are good, and waste emulsion explosive or emulsification are friedMedicine matrix is filled in the space of ammonium nitrate-fuel oil mixture, because waste emulsion explosive or process of dynamite substrate are explosibility component, more hasBe beneficial to and improve effective charge density.
3, the present invention has effectively utilized waste emulsion explosive or process of dynamite substrate, has well solved waste emulsion explosiveOr process of dynamite substrate safe handling problem.
4, the preparation technology of the granular ammonium nitrate-fuel oil mixture of viscosity of the present invention is simple, convenient for production, is convenient to on-the-spot a large amount of production of explosionUse.
5, the present invention, by first add water in polyacrylamide, prepares gluey polyacrylamide, has avoided water and blast groupThe direct contact dividing; In hybrid mode, first waste emulsion explosive or the process of dynamite substrate by water resistant is coated ammonium nitrate simultaneously,Add again moisture gluey polyacrylamide, make explosive component and moisture gluey polyacrylamide isolation, stopped water to nitric acidThe dissolved destruction effect of ammonium, is conducive to ensure product sensitivity to initiation and shelf-life.
