Abstract
The invention provides composite wax for powder type emulsion explosive. The invention is made by again compounding the basic raw materials of petroleum wax, decompressing cerate and foots oil all produced during the petroleum processing process. Compared with the prior art, the invention has the advantages of low cost, board source, prolonging the storing time of the powder type emulsion explosive at the same time of increasing the explosion performance of the powder type emulsion explosive, and vastly decreasing the cost of the powder type emulsion explosive.
Description
Technical field
The present invention relates to a kind of compound wax that is used for powdery emulsifying explosive.
Background technology
Powdery emulsifying explosive is a kind of civil blast explosive with international most advanced level of later 1990s invention, it be by over-saturation oxidizing agent solution and oil phase under the effect of emulsifying agent, the powder type explosive that spraying drying is made after 140 ℃ of emulsification.It had both had the good water repelling property of emulsion explosive, and component does not contain TNT, and environment and human body are not had any harm, having complied with people's blasting powders does not have the development trend of ladderization, possesses the solid form feature of powdery ammonium ladder detonator again, shelf-stable, quick-fried power (capacity for work) height uses advantages such as more flexible.Powdery emulsifying explosive has not only overcome the Emulsion Explosive Stability difference but also has overcome the shortcoming of powder type explosive water resisting property difference.
Powdery emulsifying explosive has very big difference from fill a prescription production technique and emulsion explosive and powder type explosive, moisture (weight) 12%～14% of preparation of emulsifying explosive, and 80 ℃ of emulsifying temperatures, powdery emulsifying explosive is moisture only 2%～4%, about 140 ℃ of emulsifying temperatures.Its production unit technology also has than big-difference, though the effect of Wax special is all the foreign minister, powdery emulsifying explosive is higher to the emulsifying film requirement of strength that Wax special forms, and is convenient to spray into powder after the emulsification, and the non-caked one-tenth piece of Cheng Fenhou normal temperature.Emulsion explosive normal temperature is paste, can not spray into powder.Powder type explosive is that Material Physics mixed grindings such as ammonium nitrate, TNT, wood powder, oil phase form, Wax special forms coating layer on the ammonium nitrate granule surface, be all powdery with the powdery emulsifying explosive apparent condition, but its microtexture difference, the water-in-oil particle of powdery emulsifying explosive is thinner, and reductive agent (Wax special) contacts tightr with oxygenant.Because powdery emulsifying explosive is different fully with the character and the production process of emulsion explosive and powder type explosive, therefore, the character of oil phase is required also different fully, the oil phase material (as CN99113309.9, CN99113308.0, CN99113295.5, CN99113294.7, CN02109421.7 etc.) that is used for the oil phase material (as CN96106444.7, CN96106443.9, CN96106442.0 etc.) of emulsion explosive and is used for powder type explosive can not be used for powdery emulsifying explosive.
MF that Fushun Petrochemical Research Institute succeeds in developing series emulsion explosive specific complex wax and DT type firer Wax special is respectively applied for emulsion explosive and powder type explosive is all obtained better result of use, but can not satisfy the powdery emulsifying explosive requirement.CN91107080.X has proposed a kind of powder emulsified ammoniumnitrate explosives that is used for engineering explosion, and its oil phase feature consists of: 1.5～2.0 (T-155 emulsifying agents), 1.0～1.5 rosin, 0.75～1.0 paraffin, 0.75～1.0 ceresine; CN00112373.4 has proposed a kind of Permitted Detonator for Coal Mining powdery emulsifying explosive, its oil phase is characterised in that and consists of: paraffin 1.5%～4%, ceresine 0.3%～1.5%, rosin 0.3%～1.5%, sorbitol monooleate 0.3%～1.0%, solidifying agent high fatty amine, acid amides or cats product 0.1%～0.5%.The oil phase of above Patent right requirement is compositions such as paraffin, ceresine, rosin, and emulsifying agent is T-155 or T-152 or sorbitol monooleate.The powdery emulsifying explosive of all these reports is the oil phase basic raw material with the petroleum refinement product all, and cost is higher.
Summary of the invention
At the deficiencies in the prior art, the invention provides a kind of lower-cost powdery emulsifying explosive Wax special composition.
The main body of powdery emulsifying explosive compound wax of the present invention contains (in compound wax weight):
Petroleum wax 10%-40%
Decompression slack wax 50%-85%
Sweat oil 0%-20%
Polymkeric substance 0%-5%
Wherein petroleum wax is 54

#One or more mixtures in the mixed crystal wax etc.The decompression slack wax is the second line of distillation slack wax, subtracts three-way slack wax, subtracts one or more mixtures in four line slack waxs and the frivolous pitch wet goods.Sweat oil is vacuum distillate or decompression slack wax are produced petroleum wax through press for extracting juice wax sweating or solvent deoiling dewaxing a by-product oil.Sweat oil can be regulated the spraying dispersing property in the powdery emulsifying explosive production process well, and spray process is realized smoothly, and the sweat oil consumption is preferably 4%～15%.
Powdery emulsifying explosive compound wax of the present invention also contains the polymkeric substance of 0-5w%.Polymkeric substance comprises that number-average molecular weight is the oligopolymer of 500-100000, as in polyethylene (PE), polypropylene (PP), polyisobutene (PIB) and the ethene-vinyl acetate copolymer (EVA) etc. one or more.Polymkeric substance can improve the one-tenth membrane stability of compound wax, improves the stability in storage of powdery emulsifying explosive, and optimum amount is 1%～5%.
The powdery emulsifying explosive compound wax advantage that the present invention proposes is to determine suitable raw material and content, makes to have good cooperation effect in the time of can being used for powdery emulsifying explosive, makes that powdery emulsifying explosive production is smooth, dependable performance.SEMI-REFINED PARAFFIN WAX that powdery emulsifying explosive compound wax use cost of the present invention is cheap and unpurified decompression slack wax, raw material sources are wide on the one hand, reduce the feed purification cost, have the sulphur, nitrogen, oxygen, metal of certain content, the material that the aromatic hydrocarbons isopolarity is stronger simultaneously, increase the polarity and the easy milkiness of compound wax to a certain extent, helped improving the performance of powdery emulsifying explosive.
With compound wax of the present invention is oil phase and be that oil phase prepares powdery emulsifying explosive and compares with petroleum refinement products such as paraffin, ceresine, rosin, blast performance and stable storing performance do not reduce, and the oil phase cost reduces significantly, the corresponding powdery emulsifying explosive cost that reduced, have good economic benefits, have good use properties simultaneously.
