The invention provides a special composite oil phase for an emulsion explosive and a preparation method thereof, which belong to the technical field of explosive composition. 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 the blasting explosives compsn technical field, be specifically related to a kind of emulsion [explosive specific complex oil phase and preparation method thereof.
Background technology
Emulsion [explosive is that the fine droplets with aqueous oxidizing agent solution is a disperse phase, is suspended in to contain in the continuum that constitutes 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 one type of water-fast organic cpds, and it mainly acts on is to form the oil film that coats interior phase particle.It forms the w/o type emulsion 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 different stickinesses and good security be provided with variation of temperature.Because there is the unstable on the thermodynamics in emulsion [explosive, different oil phase materials will directly influence size, distributing homogeneity and the stability thereof of latex particle, and in addition, different oil phase materials is also inequality to the stabilization of sensitization bubble.Therefore, preparation fine oil phase material is the key that promotes the 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 of refinery source is different; The Chemical Composition of the intermediate product of the crude oil in different oil fields after refining has a great difference; So be difficult to keep stable as the quality of the emulsion [explosive oil phase of raw material production, it is low that the finished product explosive property that causes producing also has height to have.Chinese patent CN1031401C, CN1120824C; U.S. Pat 4790890 discloses with one or more of paraffin, Microcrystalline Wax, oil fuel, Vaseline, pitch and MO and has been in harmonious proportion, and these prescriptions are raw material with the petroleum refining product, have stablized the oil phase quality; But because the emulsifying device of explosive production producer use both at home and abroad is different; The selection of emulsifying agent is different, and the requirement of oil phase also is not quite similar, and a kind of wax that is in harmonious proportion is difficult to the different emulsifying agent of coupling.The emulsion [explosive specific complex oil phase that it is raw material that Chinese patent CN101560128A has proposed by Span-80, macromolecule emulsifier, compound wax, polyethylene wax, No. 70 Microcrystalline Waxes.This method with emulsifying agent be in harmonious proportion wax premix before producing explosive owing to be in harmonious proportion the wax complicated component, residual acid or alkali and other impurity very easily cause Span-80 to decompose in the petroleum refining process, influence follow-up emulsifying effectiveness.In addition, the emulsion [explosive shelf lives of this oil phase production has only 180 days, just reaches the requirement of GB 18095-2000, can't satisfy the requirement of exported product long pot life, and explosive property still has deficiency.
Summary of the invention
Deficiency in view of prior art the objective of the invention is to through a large amount of experimental studies, and a kind of novel emulsion explosive specific complex oil phase and preparation method thereof is provided, to solve the problem that existing emulsion [explosive performance is not high, the decay of detonation ability is too fast, the shelf lives is short.
The objective of the invention is to realize like this:
A kind of emulsion [explosive specific complex oil phase be made up of Span-80, soybean lecithin, Vaseline, Microcrystalline Wax, paraffin, compound wax, and the weight percent of each component is:
The preparation method of described emulsion [explosive specific complex oil phase comprises the steps:
(1) San-80 after will weighing and soybean lecithin add reaction kettle, are heated to 80-85 ℃ and insulation, stirred simultaneously 120 minutes, after the filtration emulsifying agent;
(2) Vaseline after will weighing, Microcrystalline Wax, paraffin, compound wax add reaction kettle, and heating is opened when material melts fully and stirred, and keeps temperature of charge 90-95 ℃, and churning time 120 minutes must be in harmonious proportion wax after the cooling;
When (3) producing emulsion [explosive, with emulsifying agent be in harmonious proportion wax by 1: 2 quality than melt-blended after or melt after mix, must emulsion [explosive specific complex oil phase.
Compared with prior art, emulsion [explosive specific complex oil phase that the present invention relates to and preparation method thereof has following advantage and obvious improvement:
(1) this compound oil phase is made up of Span-80, soybean lecithin, Vaseline, Microcrystalline Wax, paraffin, compound wax, and raw material sources are wide, and are with low cost.
(2) the finished product explosive medicine attitude of utilizing this compounded oil to produce mutually is good, and hardness is suitable, becomes breast effective; Steady bubble ability is strong, and forming bubble is closed bubble, and focus efficient is high; The detonation ability is strong, and performance degradation is slow, and the shelf lives is long; Shelf lives was specially adapted to export the requirement to the explosive product long pot life greater than 15 months, had solved the short problem of emulsion [explosive shelf lives that the spans emulsifying agent is produced.
(3) simple, the steady quality of preparing method's technology of this compound oil phase through mediation wax viscosity, hardness, dropping point and oleaginousness are reasonably allocated, makes the emulsifying capacity of mediation wax and emulsifying agent accomplish good coupling.Simultaneously,, avoided mixing destruction in advance, helped follow-up emulsifying effectiveness Span-80 through emulsifying agent is mixed when producing explosive with mediation wax.Can accomplish good coupling with the emulsifying capacity of emulsifying agent.
