The composite oil phase comprises Span-80, soybean lecithin, vaseline, a microcrystalline wax, a paraffin wax and a composite wax, wherein during producing the emulsion explosive, an emulsion and a blending wax are melted after being mixed or mixed after being melted according to a mass ratio of 1:2 so as to obtain the special composite oil phase for the emulsion explosive. By using the composite oil phase provided by the invention, the problems of low performance, over-quickness for damping detonation capacity as well as short storage period of the traditional emulsion explosive are solved; and the special composite oil phase for the emulsion explosive, provided by the invention, can be used for producing the special composite oil phase materials for the emulsion explosive.
Description
Technical field
The invention belongs to blasting explosives composition technical field, be specifically related to a kind of Special composite oil phase for emulsion explosive and preparation method thereof.
Background technology
Emulsion explosive is that to take the fine droplets of aqueous oxidizing agent solution be disperse phase, is suspended in and contains in the continuum forming like oily substance that disperses bubble or hollow glass micro-ball or other porous material, the special emulsification system of a kind of water-in-oil-type of formation.The oil phase material of emulsion explosive can be broadly interpreted as the water-fast organic compound of a class, and its Main Function is the oil film that forms coated interior phase particle.It forms w/o type emulsion together with the oxidizer salt aqueous solution, be one of key ingredient of emulsion explosive, oil phase material must have good water repelling property, suitable apparent condition, can variation with temperature provide different stickinesses and good security.Because emulsion explosive exists the unstable on thermodynamics, different oil phase materials will directly affect size, distributing homogeneity and the stability thereof of latex particle, and in addition, different oil phase materials is not identical to the stabilization of sensitization bubble yet.Therefore, the oil phase material of preparation high-quality is the key that promotes emulsion explosive performance.
Chinese patent CN1174181A, CN1174182A, the disclosed oil phase material of CN1174183A are mainly the intermediate product of petroleum refining process, comprise atmospheric distillate, vacuum distillate, decompression slack wax, residual oil slack wax, frivolous asphalt oil and heavy deasphalted oil etc.Because the crude oil source of refinery is different, the Chemical Composition of the intermediate product of the crude oil in different oil fields after refining has a great difference, therefore the quality as the emulsion explosive oil phase of raw material production is difficult to maintain stable, it is low that the finished explosive products performance that causes producing also has height to have.Chinese patent CN1031401C, CN1120824C, US Patent No. 4790890 disclose with paraffin, Microcrystalline Wax, oil fuel, Vaseline, pitch and mineral oil one or more be in harmonious proportion, these formulas be take petroleum refining product as raw material, stablized oil phase quality, but because the emulsifying device that explosive production producer is used is both at home and abroad different, the selection of emulsifying agent is different, and the requirement of oil phase is also not quite similar, and a kind of wax that is in harmonious proportion is difficult to the emulsifying agent that coupling is different.The Special composite oil phase for emulsion explosive that it is raw material that Chinese patent CN101560128A has proposed by Span-80, macromolecule emulsifier, compound wax, polyethylene wax, No. 70 Microcrystalline Waxes.The method is emulsifying agent and the wax premix before producing explosive that is in harmonious proportion, and owing to being in harmonious proportion wax complicated component, in petroleum refining process, residual acid or alkali and other impurity very easily cause Span-80 to decompose, and affect follow-up emulsifying effectiveness.In addition, the emulsion explosive shelf lives that this oil phase is produced only has 180 days, just reaches the requirement of GB 18095-2000, cannot meet the requirement of exported product long pot life, and explosive property still has deficiency.
Summary of the invention
In view of the deficiencies in the prior art, the object of the invention is to study by lot of experiments, provide a kind of novel emulsion explosive specific complex oil phase and preparation method thereof, the problem that existing emulsion explosive performance is not high to solve, the decay of detonation ability is too fast, the shelf lives is short.
The object of the present invention is achieved like this:
A Special composite oil phase for emulsion explosive, is comprised of Span-80, soybean lecithin, Vaseline, Microcrystalline Wax, paraffin, compound wax, and the weight percent of each component is:
The preparation method of described Special composite oil phase for emulsion explosive, comprises the steps:
(1) San-80 after weighing and soybean lecithin are added to reactor, be heated to 80-85 ℃ and insulation, stir 120 minutes simultaneously, after filtration, obtain emulsifying agent;
(2) Vaseline after weighing, Microcrystalline Wax, paraffin, compound wax are added to reactor, heating open to be stirred when material melts completely, maintains temperature of charge 90-95 ℃, and churning time 120 minutes must be in harmonious proportion wax after cooling;
(3) while producing emulsion explosive, by emulsifying agent be in harmonious proportion wax and mix afterwards or after melting by the mass ratio of 1: 2 is melt-blended, obtain Special composite oil phase for emulsion explosive.
Compared with prior art, the Special composite oil phase for emulsion explosive the present invention relates to and preparation method thereof tool has the following advantages and is significant progressive:
(1) this composite oil phase is comprised of Span-80, soybean lecithin, Vaseline, Microcrystalline Wax, paraffin, compound wax, and raw material sources are wide, with low cost.
(2) the finished explosive products medicine state of utilizing this composite oil phase to produce is good, hardness is suitable, becomes breast effective, and the ability of surely steeping is strong, forming bubble is closed bubble, focus efficiency is high, and detonation ability is strong, and performance degradation is slow, shelf lives is long, shelf lives is greater than 15 months, is specially adapted to the requirement of outlet to explosive product long pot life, has solved the shorter problem of emulsion explosive shelf lives that spans emulsifying agent is produced.
(3) simple, the steady quality of preparation method's technique of this composite oil phase, by reasonably allocating being in harmonious proportion wax viscosity, hardness, dropping point and oleaginousness, the wax that makes to be in harmonious proportion has been accomplished good coupling with the emulsifying capacity of emulsifying agent.Meanwhile, by emulsifying agent is mixed when producing explosive with mediation wax, avoided mixing in advance the destruction to Span-80, be conducive to follow-up emulsifying effectiveness.Can accomplish good coupling with the emulsifying capacity of emulsifying agent.
