Description
Technical field
The present invention relates to cutting fluid technical field, particularly relate to a kind of micro-emulsion cutting fluid of stable performance.
Background technology
Metal cutting is a kind of application working method widely, and can produce very large friction and heat between cutter and workpiece in working angles, this not only affects the quality of working (machining) efficiency and workpiece, also can cause damage to cutter and equipment.Therefore having the cutting fluid of good lubrication, cooling, cleaning and rustless property, is the target always pursued in metal cutting process.
In recent years, rapidly, new metallic material is continually developed and is applied, and intermetallic composite coating speed and load improve constantly in metalworking technology development, and this just requires that metal working fluid supporting is with it constantly updated and regenerates.Be divided into oil base and water base two large classes according to processing oil composition and medium state both at home and abroad at present, they respectively have superiority in different process engineerings, and the former has excellent oilness and rustless property, and it is more superior that the latter cleans cooling performance.In order to meet the different market requirements, oil base is water base and deposit, and microemulsified is the development trend of metal working fluid, and is received by the market very much.
Traditional micro-emulsion cutting fluid is oil based on mineral oil, in use easily putrid and deteriorated, corrosion machine part, and the smell is awful, affects workman healthy, and biological degradation rate is low, contaminate environment, poor stability, and work-ing life is short.
Summary of the invention
The present invention proposes a kind of microemulsified metal working fluid of stable performance, its stable performance, is easy to biological degradation, long service life, and rust-preventing characteristic, oilness and cleansing power are strong.
The present invention proposes a kind of microemulsified metal working fluid of stable performance, by weight containing following component: rapeseed oil 20-35 part, pentaerythritol fatty ester 15-20 part, anion surfactant 15-25 part, nonionogenic tenside 15-25 part, α-amino isopropyl alcohol 3-8 part, alcohol 3-10 part, rust-preventive agent 15-25 part, stablizer 5-12 part, polysiloxane defoamers 1-3 part, sterilant 2-4 part, water 100-150 part.
