Description
Technical field
The present invention relates to a kind of electric spark oil, especially relate to a kind of electric spark oil for Mirror EDM
And preparation method thereof.
Background technology
Electric spark oil is that the cooling that mould molding lathe (spark-erosion machine tool, also cry electric pulse lathe) is processed is special
Medium.As far back as 80, the nineties, tradition spark machined, great majority kerosene, do machining medium, later
From Taiwan, south China to continent is coastal etc., and mould of plastics makes area, begins to use special electric spark oil, and this is
A kind of viscosity is at the low viscosity of about 1.5-3.0, the CH mixture of the low aromatic hydrocarbon of solvent-borne type.
At present in China's Mainland, Hong Kong, TaiWan, China, the common electric spark oil on market, kind is miscellaneous, matter
Measure on the low side, use rear color easily to deepen, turn yellow；Sometimes the abnormal flavour that the smell of burning, paint-like flavour etc. are pungent, acid are had
Change sulfide, greasy filth produces fast, and mould gets rusty increased risk, this chip resistance that can cause medium member and carbon deposit row
Except performance can quickly be deteriorated, it is impossible to ensure stable machining accuracy.Although additionally, existing electric spark oil slightly adds
The thick corrosion rate of work is relatively fast, but higher arene content (5%---26%), skin is also had dissolving and thorn
Swash effect.
Along with the mirror finish of specific novel alloy material product is wanted by Chinese high-end sophisticated manufacturing, aircraft industry
Asking, high-end Mirror EDM lathe of new generation comes out therewith.And existing electric spark oil is above-mentioned intrinsic because of it
Defect, the needs of mirror finish cannot be met at all.
Summary of the invention
After the technical problem to be solved is to provide a kind of use, color is difficult to deepen, turn yellow；There is no Jiao
The abnormal flavour that taste, paint-like flavour etc. are pungent, is not likely to produce acidifying sulfide and greasy filth, and stimulates less to human body skin
Environmental protection for Mirror EDM electric spark oil and preparation method thereof.
