The viscous and granular anfo explosive disclosed by the invention effectively uses the waste emulsion explosive or the emulsion explosive matrix, well solves the problems of safety treatment on the waste emulsion explosive or the emulsion explosive matrix, is simple in preparation process and convenient in production, and is convenient for large-scale production and application of blasting sites.
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 industrial 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, improve blast hole utilizing factor, people have developed terraced glutinous pellet explosive.This explosive is mixed by ammonium nitrate, diesel oil and thickness explosive agent, existing certain fluidity has again suitable tackiness, has substantially solved the problem that charge pneumatic machinery process is returned medicine.But owing to containing 1/3 tritonal in added thickness explosive agent, in producing and using, unavoidably workman is worked the mischief.For addressing this problem, Chinese patent literature " viscous granular Non-TNT explosive " (application number: 85100393), " non-TNT sticky charge and manufacture method thereof " (application number: 89107503.8), " a kind of ammonium nitrate-fuel oil mixture " (application number: 201210225182.3) etc. disclose separately without terraced viscous explosive formula and preparation method, its theme thinking is all to take nontoxic methylamine nitrate to substitute the TNT that toxicity is larger as sensitizing agent, but methylamine nitrate is extremely responsive as a kind of single chmical compound explosive, production process is complicated, technology controlling and process is had relatively high expectations, do not meet on-site mixed explosive sensitivity low, produce simple requirement, in the middle of production and use procedure, exist great potential safety hazard.In patent documentation 89107503.8, add aluminium powder, sulphur to bringing larger dust and blast, danger of combustion in the middle of producing, and in explosion product, contained more sulfur dioxide pollution air.Chinese patent literature (application number: 200610010603.5) disclose a kind of glutinous pellet explosive, cancelled the use of the responsive single chmical compound explosives such as TNT, methylamine nitrate, greatly reduce blast, danger of combustion characteristic in production process, but still used calcium carbonate, talcum powder, hollow glass microballoon etc. easily to generate the component of a large amount of dust, in the solid powder adding, 30% is the very little hollow glass microballoon of density, having offset the density of bringing after calcium carbonate, talcum powder add increases, limited on charge density impact.Solid meal component has absorbed a large amount of heats in explosive reaction, and the gas of generation is limited, and quick-fried heat is had a certain impact.
The current development along with the high sensitization of emulsion explosive, high temperature Charge and popular, the domestic emulsion explosive production overwhelming majority of producer has adopted heat-sensitized technology, heat-sensitized technology is bringing large production capacity, high efficiency while also to produce the useless medicine of a large amount of emulsification and matrix, emulsion explosive production security incident took place frequently due to 2013 to 2014, responsible departments of the government's feed bin before security standpoint considers to have forbidden that the useless medicine producing stub bar, material tail and debug process is joined to powder charge is processed, and processes to current useless medicine and 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, the granular ammonium nitrate-fuel oil mixture of viscosity and preparation method that production process is easier.
Technical scheme of the present invention is as follows:
The granular ammonium nitrate-fuel oil mixture of viscosity, feed composition is as follows, is weight part:
According to the present invention, preferred, the granular ammonium nitrate-fuel oil mixture of described viscosity, feed composition is as follows, is weight part:
According to the present invention, preferred, the granular ammonium nitrate-fuel oil mixture of described viscosity, feed composition is as follows, is weight part:
According to the present invention, preferred, the particle diameter of described powdered polypropylene acid amides is 0.1～1mm;
Preferably, described gluey polyacrylamide is by polyacrylamide: water=1:(7～12) mass ratio is mixed to get, 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) by above-mentioned weight part, in mixing tank, add ammonium nitrate, 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, obtain.
The present invention is mixed to get ammonium nitrate-fuel oil mixture by ammonium nitrate and diesel oil, with waste emulsion explosive or the coated ammonium nitrate-fuel oil mixture of process of dynamite substrate, can improve water repelling property and Sensitivity to Primary Explosion; Waste emulsion explosive or process of dynamite substrate are filled in the space of ammonium nitrate-fuel oil mixture, can improve effective charge density.The present invention by first adding water in polyacrylamide, prepare gluey Polyacrylamide, avoided water to contact with the direct of explosive component, first with waste emulsion explosive or the process of dynamite substrate of water resistant, be coated ammonium nitrate, add again moisture gluey Polyacrylamide, make explosive component and moisture gluey Polyacrylamide isolation, be conducive to guarantee product Sensitivity to Primary Explosion and quality guaranteed period.Add powdered polypropylene acid amides can make the viscosity of product best.
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 Primary Explosion is moderate, and available common emulsion explosive 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 Primary Explosion are good, waste emulsion explosive or process of dynamite substrate are filled in the space of ammonium nitrate-fuel oil mixture, because waste emulsion explosive or process of dynamite substrate are explosibility component, be more conducive to improve effective charge density.
3, the present invention has effectively utilized waste emulsion explosive or process of dynamite substrate, has well solved waste emulsion explosive or 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 the on-the-spot a large amount of production and applications of explosion.
5, the present invention, by first add water in polyacrylamide, prepares gluey polyacrylamide, has avoided water to contact with the direct of explosive component; 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, stop the dissolved destruction effect of water to ammonium nitrate, be conducive to guarantee product Sensitivity to Primary Explosion and quality guaranteed period.
