Abstract
The invention relates to a water-in-oil type electric spark machining working solution in the field of non-traditional machining, comprising compound emulsifying agent, engine oil and deionized water. The working solution is prepared by the following steps: sorbitan monoleate and polyoxyethylene sorbitan monostearate are put together in proportion, stirring for the sorbitan monoleate and the polyoxyethylene sorbitan monostearate to mix and react and form the compound emulsifying agent; the prepared compound emulsifying agent is added into the engine oil according to a required proportion, stirring for the compound emulsifying agent to be dissolved into the engine oil and form an engine oil colliquefaction solution; and the deionized water is added into the engine oil colliquefaction solution, stirring to obtain the water-in-oil type electric spark machining working solution. The water-in-oil type electric spark machining working solution has the advantages of high dielectric strength, safe use, no pollution and high electric spark machining efficiency.
Description
Technical field
The present invention relates to the water-in-oil type electric spark machining working solution in a kind of special process field.
Background technology
At present, spark machined working solution commonly used has oils working solution and water base working solution both at home and abroad.
The oils working solution mainly contains kerosene, special-purpose mineral oil, synthesis type wet goods.The kerosene application in China's Electric Discharge Machining at present is still comparatively extensive, its major advantage is the dielectric strength height, viscosity is low and good fluidity, its shortcoming is that flash-point is low, volatility big, poor stability, and the fire hazardous accident decomposites pernicious gas etc. in the processing.Special-purpose mineral oil has certain overcoming to some shortcomings of kerosene, but contains a certain amount of aromatic hydrocarbons in such mineral oil, causes the poor stability of oil product, and frowziness also has spread effect to skin.Synthesis type oil mainly make a comment or criticism structure alkane and isoparaffin, owing to do not add phenolic antioxidant, therefore, oily color water-white is bright, the content of aromatic hydrocarbons is extremely low, basic free from extraneous odour.In order to improve the spark machined effect of synthesis type oil, people again on this basis, add additives such as polybutene, developed as companies such as Japan National Oil Corp, auspicious soil, Germany and to have added polybutene, ethene, the polymer of vinyl group and ring benzene class aromatic compound etc., behind the adding polymer, the polymer that boiling point is high will destroy steam blanket rapidly, improve cooling effectiveness, can improve the working (machining) efficiency of electric spark.These additive cost height, technology are difficult for grasping, and institute adds fatty hydrocarbon polymer and easily causes arc phenomenon.
Water base working solution mainly contains emulsion, deionized water etc.Emulsion mainly by oil emulsion, emulsification soap and water-soluble close formulated, the micro emulsion of the emulsion that is made into drips based on oil-in-water, its dielectric strength is more much lower than oils working solution, usually there is certain electrolysis in the spark machined, such working solution is mainly used in Wire EDM, the processing of electric spark high speed aperture at present, is not suitable for Electric Discharge Machining.Deionized water has advantages such as cost is low, nonflammable, free from environmental pollution, domestic and international many scholars study as electric spark machining working solution adding certain additive in deionized water or the deionized water, such working solution mainly is applicable to fine electric spark processing at present, be not suitable for Electric Discharge Machining, its main cause is that working (machining) efficiency is low, and easy-to-rust lathe and workpiece.
Summary of the invention
The object of the present invention is to provide a kind of water-in-oil type electric spark machining working solution, solve preferably that the oils working solution that spark machined uses is volatile, flash-point is low, cost is high, and the dielectric properties of water base working solution are poor, have in the process electrolysis to have, be not suitable for the problem of Electric Discharge Machining etc.
Principle of the present invention is: require in proportion earlier sorbitan mono-oleic acid ester and polyoxyethylene sorbitan monostearate are put together, stir and make their hybrid reaction formation compound emulsifying agent; Require in proportion then the compound emulsifying agent of being prepared is joined in the machine oil, stirring is dissolved in the machine oil compound emulsifying agent, forms the fused liquid of machine oil; In the fused liquid of machine oil, add deionized water at last, stir and just can obtain the water-in-oil type electric spark machining working solution that to prepare.
Water-in-oil type electric spark machining working solution of the present invention have the dielectric strength height, nonflammable, safe in utilization, pollution-free, can improve advantages such as spark machined efficient.
The specific embodiment
The first step is put sorbitan mono-oleic acid ester and polyoxyethylene sorbitan monostearate together by quality proportioning 99:7, stirs to make them hybrid reaction form compound emulsifying agent; Second step is by quality proportioning 1:(5～7), compound emulsifying agent of being prepared and machine oil to be put together, stirring is dissolved in the machine oil compound emulsifying agent, forms the fused liquid of machine oil; Quality proportioning 1:(5～7 that the 3rd step press compound emulsifying agent, machine oil and deionized water): the relation of (2～5), in the fused liquid of machine oil, add deionized water, stirring just can obtain the water-in-oil type electric spark machining working solution that will prepare.
