Etc.
Description
Technical field
The invention belongs to special process field, relate to a kind of water-in-oil type mixed powder working solution.
Background technology
At present, spark machined working solution commonly used has oils working solution and Water-based working liquid for electrical both at home and abroad.
The oils working solution mainly comprises kerosene, special-purpose mineral oil and synthesis type wet goods.Kerosene has higher dielectric strength, low viscosity and good flowability, be spark machined working solution commonly used, but the flash-point of kerosene is low, volatility is large, stink is large, poor stability, the fire hazardous accident.Special-purpose mineral oil has certain overcoming to some shortcomings of kerosene, but contains a certain amount of aromatic hydrocarbons in such oil, causes the poor stability of oil product, and frowziness also has spread effect to skin.Synthesis type oil mainly comprises n-alkane and isoparaffin, owing to do not add phenol antioxidant, therefore, the color water-white of oil is bright, and the content of aromatic hydrocarbons is lower, basic free from extraneous odour.In order to improve the processing effect of oils working solution, people have added solid additives or liquid modifying agent in the oils working solution, solid additives mainly contains silica flour, aluminium powder, carborundum powder and some inorganic oxide powders, liquid modifying agent mainly contains alkane, aromatic compound, non-ionic surface active agent etc., the adding of these additives, can cause the change of discharge channel structure, increase discharging gap, therefore can improve working (machining) efficiency, improve machined surface quality, but the main component of working solution is high-molecular hydrocarbons, needs to consume a large amount of petroleum resources, and the working solution after the processing is difficult to process, easily contaminated environment.
Water-based working liquid for electrical mainly contains emulsion and deionized water etc.Emulsion is mainly formed by oil emulsion or emulsification soap and water mixed preparing, the micro emulsion of the emulsion that is made into drips take oil-in-water as main, its dielectric strength is more much lower than oils working solution, there is certain electrolysis in the process, such working solution is generally used for Wire EDM, high speed electric spark small hole processing at present, is not suitable for Electric Discharge Machining.Deionized water has the advantages such as cost is low, nonflammable, free from environmental pollution, domestic and international many scholars are studied as 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, main cause is that the puncture pressure drop is large, working (machining) efficiency is low.
Summary of the invention
The object of the present invention is to provide a kind of water-in-oil type mixed powder working solution.
Principle of the present invention is: require in proportion sorbitan mono-oleic acid ester is joined in the machine oil first, add thermal agitation and make it be dissolved in machine oil, form the machine oil mixed liquor; Then require in proportion to add APES and rosin, add thermal agitation they are dissolved in the machine oil mixed liquor; In mixed liquor, add deionized water again, stir and obtain water-in-oil type emulsion; Add the aluminium micro mist in the most backward water-in-oil type emulsion, stir and just can obtain the water-in-oil type mixed powder working solution that to prepare.
Water-in-oil type mixed powder working solution of the present invention and more even than the suspension with solid particle, the difficult precipitation of the mixed powder liquid phase of kerosene commonly used, nonflammable, pollution-free, the advantages such as cost is low, use safety, working (machining) efficiency height, machined surface quality.
The specific embodiment
The first step in mass ratio 1: (3～5), sorbitan mono-oleic acid ester is joined in the machine oil, add thermal agitation and make it be dissolved in machine oil, form the machine oil mixed liquor; Second step is pressed the quality proportioning 1 of sorbitan mono-oleic acid ester, APES, rosin, machine oil: (0.05～0.15): (0.10～0.15): the relation of (3～5), in the machine oil mixed liquor, add APES and rosin, add thermal agitation and obtain mixed liquor; The 3rd step was pressed the quality proportioning 1 of sorbitan mono-oleic acid ester, APES, rosin, machine oil, deionized water: (0.05～0.15): (0.10～0.15): (3～5): the relation of (2～6), in mixed liquor, add deionized water, stir and obtain water-in-oil type emulsion; The 4th step was that 5～10 microns aluminium micro mist joins in the water-in-oil type emulsion with particle diameter, added 5～10 gram aluminium micro mists in every liter of emulsion, stirred and just can obtain the water-in-oil type mixed powder working solution that will prepare.
