Description
Technical field
The present invention relates to a kind of processing method of special-purpose emulsifying explosive, what particularly a kind of suitable sulfur-bearing mine blasting was used
Special-purpose emulsifying explosive processing method.
Background technology
Each key industry explosive production big country of the current world, occurs much to play accident in sulfur-bearing mine blasting, causes
Scientific research institution, explosive production enterprise and the attention very high of explosion unit, foreign countries have been carried out deeply and careful research to this,
Such as USP6125761, USP6051086 and USP 5159153, the Related product of seriation has been formd at present, and the country is to this
That studies is relatively fewer, and the product without seriation.
With reference to the achievement in research of forefathers, it is believed that cause sulfur-bearing mine blasting accident basic reason to be ammonium nitrate and sulfur-bearing chemical combination
Thing reacts at relatively low temperature, causes heat accumulation, causes the accident such as early quick-fried, so fundamental way is to prevent nitric acid
Contact of the ammonium with sulfur-containing compound or the decomposition of suppression ammonium nitrate, most of use adds nitric acid in foreign countries' open source literature at present
The method of ammonium decomposing inhibitor reaches the purpose of safety blasting.Due to being influenceed not by temperature, pH value and reducing substances concentration
Together, the method can sometimes be subject to certain notable.Based on this analysis, we make when selecting emulsion as sulfur-bearing mine blasting
Explosive, is kept apart ammonium nitrate and sulfur-containing compound using oil film.
Emulsion is that ammonium nitrate and other oxidants form aqueous oxidizing agent solution with water, after emulsifying agent and oily mixed melting
Oil phase emulsion is formed, uniform Water-In-Oil shape emulsion is formed under high speed shear effect.Due to the unique texture of emulsion
And oxidant is relative abundant with what reducing agent was contacted.Emulsion since the birth, due to its excellent explosion property, relatively
Compare safety, be easy to automated production, paid attention to by countries in the world, swift and violent development is obtained, as the main of commercial explosive
Kind, in Industrial Explosive in Our Country product, emulsion accounts for the 70% of aggregated capacity.
The content of the invention
It is an object of the invention to overcome drawbacks described above, there is provided a kind of sulfur-bearing mine special-purpose emulsifying explosive and its preparation work
Skill.
Realizing the technical scheme of the object of the invention is：A kind of sulfur-bearing mine special-purpose emulsifying explosive, by percentage to the quality, bag
Water phase and oil phase are included, described water is mutually 65-75% ammonium nitrate, 18-25% water, 2-5% urea；Described oil phase is 1.2-
2% polyisobutene family macromolecule emulsifying agent, 2-4% Ni Nasi oil, 0.1-2% tricresyl phosphates (2- chloroethyls) ester (TCEP).
2-5% triisopropanolamines are added in described explosive.
A kind of sulfur-bearing mine special-purpose emulsifying explosive preparation technology, comprises the following steps：
The first step, water are mutually prepared：65-75% ammonium nitrate, 18-25% water, 2-5% urea are mixed and heated to 65-80 degree
Insulation；
It is prepared by second step, oil phase：By 1.2-2% polyisobutene family macromolecules emulsifying agent, 2-4% Ni Nasi oil, 0.1-2%
Tricresyl phosphate (2- chloroethyls) ester (TCEP) is mixed and heated to the insulation of 40-50 degree；
3rd step, water is mutually poured slowly into oil phase and is stirred continuously to form uniform water-in-oil emulsion.
The advantage of the invention is that described method is simply adjusted in preparing sulfur-bearing mine special-purpose emulsifying explosive to formula
It is whole, original production process is not changed, being suitable for existing production line carries out industrialized production, while the emulsion for having reached production is fitted
For the purpose of sulfur-bearing mine blasting.
