Abstract
The invention relates to water-in-oil electric spark forming machining working fluid in the field of non-traditional machining. The working fluid comprises compound emulsifiers, white mineral oil and deionized water. When the water-in-oil electric spark forming machining working fluid is prepared, sorbide oleate and the white mineral oil are mixed with each other according to proportion requirements and are uniformly stirred at first; sorbitan monooleate polyoxyethylene ether and the deionized water are mixed with each other according to proportion requirements and are uniformly stirred; prepared mixtures of the sorbitan monooleate polyoxyethylene ether and the deionized water are slowly dripped into prepared mixtures of the sorbide oleate and the white mineral oil, the mixtures are continuously stirred, accordingly, the viscosity of the mixtures is gradually increased and ultimately suddenly drops, the electric conductivity of emulsion is measured in the procedures, and a numerical value of the electric conductivity of the emulsion is increased, then drops and is ultimately equal to zero. The water-in-oil electric spark forming machining working fluid has the advantages of environmental protection, high machining efficiency and dielectric strength, safety in use and the like.
Description
Technical field
The present invention relates to the green high-efficient water-in-oil type spark-erosion sinking processing work liquid in a kind of special process field.
Background technology
Spark-erosion sinking processing work liquid has direct impact to technic indexs such as working (machining) efficiency, machining accuracy, export licenses, and the environmental protection of working solution itself, safety and service life etc., problem also caused increasing attention.
Spark-erosion sinking processing work liquid, according to its source and composition, is broadly divided into oils working solution and the large class of Water-based working liquid for electrical two at present.
Oils working solution mostly is high-molecular hydrocarbons, as kerosene, bobbin oil, transformer oil, paraffin etc., generally contains three kinds of compounds: aromatic hydrocarbon, cycloalkane and alkane.Adopt the method for distilation, can be by the compound separation of different component out.The method of for example mainly distilling containing the kerosene employing of aromatic hydrocarbon is separated from natural oil.From using the angle of safety and environmental protection, in spark-erosion sinking processing, do not advocated use kerosene, and encouraged to use more the oils containing alkane component cpd at present.Water-based working liquid for electrical mainly contains emulsion, deionized water etc., although Water-based working liquid for electrical has the advantages such as safe, pollution-free, but its insulating properties is low, compression to discharge channel is poor, electric discharge removal amount is few, and the maintenance of its insulating properties and the aspects such as the corrosivity of lathe, workpiece and processing stability energy are also existed to many problems.Keryl working solution, in spark-erosion sinking process, can discharge the pernicious gases such as benzene, hexahydrotoluene, nitrous oxide, 2-methyl hexane, kerosene steam.Sucking kerosene can stimulate respiratory tract, causes the symptoms such as cough, expiratory dyspnea, chest discomfort; And suck for a long time benzene, can to endanger people's nervous system even carcinogenic, and acute poisoning can produce that neural spasm is even gone into a coma, death.And industrial white mineral oil is the mineral oil obtaining after special deep refining, colourless, tasteless, chemical inertness, light stability are good, basic composition is saturated hydrocarbon structure, wherein the material of aromatic hydrocarbon and nitrogenous, sulphur etc. is similar to zero, is applicable to the working solution of preparation spark-erosion sinking processing.
Phase transition method has now been widely used in the preparation of emulsion, the oil solution that has added oil soluble surfactant is added drop-wise in the aqueous solution that has added water soluble surfactant active gradually, solution system has experienced burst transformation and transitional face transformation mutually, from oil-in-water (O/W) emulsion inverse, is Water-In-Oil (W/O) emulsion.In transitional face transition process, the physicochemical properties of system change, and have experienced the minimum point of interfacial tension, and the particle diameter therefore obtaining is very little.Utilize the spark-erosion sinking processing work liquid of phase transition method preparation to there is the advantages such as stable, particle diameter is little.
Summary of the invention
The object of the present invention is to provide a kind of green high-efficient water-in-oil type spark-erosion sinking processing work liquid, solve preferably the oils working solution lightning that spark machined uses lower, add volatile toxic gas and the shortcoming such as with high costs in man-hour, and Water-based working liquid for electrical dielectric properties are poor, have Electrolysis to exist in process and the problem such as corrosion lathe.
Principle of the present invention is: first require in proportion sorbitol anhydride oleate and white mineral oil mix and stir; Require in proportion sorbitan monooleate APEO and deionized water mix and stir; Then prepared sorbitan monooleate APEO and deionized water mixture are slowly added drop-wise in prepared sorbitol anhydride oleate and white mineral oil mixture, constantly stir, its viscosity rises to last decline suddenly gradually, and measure electrical conductivity, until electrical conductivity drops to 0.
Green high-efficient water-in-oil type spark-erosion sinking processing work liquid of the present invention has the advantages such as environmental protection, processing is efficient, dielectric strength is high, use is safe.
The specific embodiment
The first step, by quality proportioning 7:460, mixes sorbitol anhydride oleate and white mineral oil, stirs, second step, by quality proportioning 3:100, mixes sorbitan monooleate APEO and deionized water, stirs, the 3rd step is pressed sorbitol anhydride oleate and white mineral oil mixture, the relation of the quality proportioning 467:103 of sorbitan monooleate APEO and deionized water mixture, sorbitol anhydride oleate and white mineral oil mixture are added drop-wise in sorbitan monooleate APEO and deionized water mixture gradually, and constantly stir, mixture viscosity increases gradually and reduces suddenly, from O/w emulsion, become water-in-oil emulsion, and measure its electrical conductivity, until electrical conductivity is 0, just can obtain the green high-efficient water-in-oil type electric spark machining working solution that will prepare.
