Abstract
The present invention proposes one kind of cheap and wide-source compound wax for emulsified explosive. The compound wax is compounded with one or more of atmospheric third side-cut, vacuum first side-cut, vacuum second side-cut, vacuum third side-cut, vacuum fourth side-cut, deoiled petrolat, dewaxed oil, residual petrolat, light deasphalted oil, heavy deasphalted oil, etc. as basic material. Using the said compound wax can reduce the cost of emulsified explosive.
Description
The present invention relates to a kind of compound wax that is used for emulsion explosive.
Emulsion explosive is mainly by as the aqueous inorganic oxidizer salt solution component of disperse phase, form as the hydrocarbon fuel component of external phase, the sensitization gas composition (density adjustment agent) and emulsifying agent four parts that form disperse phase.Oil phase material mainly plays external phase and incendiary material effect in emulsion explosive, the hydrocarbon polymer that the water-fast performance of any different sources is suitable all can be used as oil phase material, the wax, oil and the polymkeric substance that comprise various sources, but consider oil phase material in emulsion process easy emulsifying property and the stability of emulsion, generally all contain long chain hydrocarbon component (as paraffin) and short chain hydrocarbon compound component (as diesel oil, lubricated wet goods).Simultaneously, for adjusting the viscosity of oil phase, generally also add a small amount of superpolymer (as PIB, EVA) owing to the petroleum products aboundresources, great variety of goods and price are lower, so petroleum refinement products such as kerosene, diesel oil, lubricating oil, Vaseline, paraffin, ceresine are used widely in emulsion explosive.
At USP3,445,890 disclose since the emulsion explosive first from H.F.Blume, and people have done a lot of improvement to emulsion explosive.USP4,790, it is oil phase that a kind of emulsion explosive of 890 propositions utilizes mineral oil, 2# oil fuel, vegetables oil, paraffin, Microcrystalline Wax etc., it is the emulsion explosive of oil phase with paraffin, Vaseline, mineral oil, stearic mixture that CN1034336A discloses a kind of, and the emulsion explosive that CN1061213A proposes is an oil phase with paraffin, ceresine, rosin.These patents adopted all based on petroleum wax, Vaseline, lubricating oil.GB2,224,501A has done a little improvement on this basis, proposes to increase aromaticity content with the increase Stability of Emulsion Explosives, but aromatic hydroxy compound volatilization and inflammable easily works the mischief to operative employee's human and environment.The emulsion explosive of all these reports is the oil phase basic raw material with the petroleum refinement product all, petroleum cuts is concocted by a certain percentage more again through oil/wax separation and purification and after making corresponding wax or oil production, not only waste the manpower and materials and the energy but also increased the cost of oil phase, thus the corresponding emulsion explosive cost that increased.
The object of the invention is rationally to utilize refinery's resource, with atmosphere 3rd side cut oil, first vacuum side stream, second line of distillation oil, subtract third fractional oil, subtract four line wet goods fractions oil and corresponding de-oiling slack wax and residue slack wax, frivolous asphalt oil, heavy and light deasphalted oil be basic material, is mixed into a kind of with low cost, emulsion explosive compound wax that stable performance is enriched in the source.Thereby avoided wax/separating of oil refining unnecessary technology of blending again, reduced the oil phase cost, thereby reduced the emulsion explosive cost.
Emulsion explosive compound wax of the present invention, it by atmosphere 3rd side cut oil, first vacuum side stream, second line of distillation oil, subtract third fractional oil, subtract four line wet goods fraction oil and de-oiling slack wax thereof, one or more mixtures of residue slack wax, frivolous asphalt oil, heavy and light diasphaltene wet goods oil intermediate product form.
The main body of emulsion explosive compound wax of the present invention contains (in compound wax weight, w%): the frivolous asphalt oil 0-15% of atmosphere 3rd side cut oil 0-5% vacuum distillate 5-40% decompression slack wax 40-90% residual oil slack wax 0-40% heavy deasphalted oil 0-15%
Wherein vacuum distillate is first vacuum side stream, second line of distillation oil, subtracts third fractional oil, subtracts four line oil and composition thereof.The decompression slack wax is the second line of distillation slack wax, subtracts three-way slack wax, subtracts four line slack waxs and composition thereof.
Emulsion explosive compound wax of the present invention also can contain natural resin or the synthetic resins of 0-5%, the polymkeric substance of 0-5%.
Natural resin or synthetic resins comprise Gum Rosin and derivative thereof, obedient olefine resin, resol, aliphatic petroleum resin, aromatic petroleum resin, hydrogenated petroleum resin.
The polymkeric substance number-average molecular weight is 500-100000, comprises second third glue, PE, PP, PIB, EVA.
The emulsion explosive compound wax advantage that the present invention proposes is rationally to utilize refinery's resource, with the oil middle distillate is the oil phase basic material, abandoned the traditional technology of concocting again behind oil/wax separation and purification, thereby avoided middle unnecessary human and material resources, energy dissipation, thereby reduced the oil phase cost significantly.It is refining that basic material of the present invention does not carry out desulfurization, denitrogenation, deoxidation, demetalization, so sulphur, nitrogen, oxygen, metal, the aromatic hydrocarbons equal size of compound wax of the present invention are higher, the polarity of compound wax is increased, thereby increased the easy milkiness of compound wax of the present invention.With compound wax of the present invention is oil phase and be that oil phase prepares emulsion explosive and compares with petroleum refinement products such as paraffin, ceresine, Vaseline, blast performance and stable storing performance do not reduce, and the oil phase cost reduces significantly, the corresponding emulsion explosive cost that reduced, have good economic benefits, have good use properties simultaneously.
Specify the present invention below by embodiment.
