Description
Technical field
The invention belongs to metal cutting processing auxiliary chemicals technical field, relate in particular to the special cutting fluid of a kind of aluminium alloy.
Background technology
Aluminium alloy is the current metal material being all widely used in industries such as motor car engine, variator, air equipment and other mechanical means, therefore aluminium alloy is processed to the demand of special cutting fluid growing, high cutting speed and the desired excellent oilness of high feed rate and cooling while requiring aluminum alloy cutting fluid to provide aluminum profile extrusion, significantly improve the work-ing life of cutter and the surface smoothness of workpiece, even and if (as drill gun, rifle hinge) still accomplished masterly when in the face of high-class deep hole machining application.Traditional aluminum alloy cutting fluid is generally made up of mineral oil and emulsifying agent, has the shortcomings such as easily difficult dilution in rancid, winter in summer, rust-proof effect be poor, and energy consumption is large simultaneously, production cost is high, serious harm environment and human body.Along with the enhancing of environmental protection consciousness, people are the important directions using the water base aluminum alloy cutting fluid of synthetic environmentally safe as research.
Prior art discloses a kind of micro quantity lubrication system aluminum alloy cutting fluid and its production and use, described aluminum alloy cutting fluid is prepared from by the raw material of following weight percent: base oil 30%, sulfide isobutene 5～20%, clorafin 5～20%, thiophosphatephosphorothioate 5～20%, potassium borate 5～20%, tensio-active agent 10%, rust-preventive agent 5%, described base oil adopts mineral oil or vegetables oil.The aluminum alloy cutting fluid of this invention has good oilness and thermal diffusivity, and usage quantity drops to original below 5%, and the discharge of river pollution is reduced, and has saved tooling cost, has improved lubricant effect.
Prior art discloses a kind of emulsification type metal cutting liquor composition, is made up of base oil or oiliness improver, mixing hydramine, anion surfactant, nonionogenic tenside, rust-preventive agent, copper alloy inhibiter, fungicidal preservative etc.The metal coolant composition highly versatile of this invention, is applicable to various metals processing, especially for the processing of Al-alloy metal, there is excellent oilness, anticorrosive effect, with low cost, and not containing hazardous and noxious substances such as nitrite, phenols, harmless to environment and operator ' s health.
Prior art discloses a kind of water-soluble metalworking liquid, is made up of the stablizer of base oil or oiliness improver, anion surfactant, nonionogenic tenside, rust-preventive agent, extreme-pressure additive, couplant, copper alloy inhibiter, anticorrosive agent, defoamer, aluminum alloy corrosion inhibitor, aluminum alloy corrosion inhibitor.Highly versatile of the present invention, be suitable for various metals, particularly be used in processing aluminium alloy part, aluminium alloy is had to splendid anti-corrosion effects, can effectively prevent the variable color of responsive aluminium alloy, there is excellent lubricity, rustless property, anti-corrupt ability and outstanding resistance to hard water ability simultaneously, can recycle for a long time and not contain the hazardous and noxious substances such as nitrite, phenols, to environment and healthy and beneficial.
Prior art discloses a kind of hard water resistant water-soluble cutting solution, is made up of base oil or oiliness improver, anion surfactant, rust-preventive agent, couplant, copper alloy inhibiter, anticorrosive agent, defoamer, aluminum alloy corrosion inhibitor.The cutting fluid of this invention can be resisted the hard water of 7000ppm, is generally applicable to the area that water hardness is high, and dilution water does not need to process and just can directly use through water demineralization, and working fluid reaches more than 2 years work-ing life; Waste liquid after the cutting fluid of this invention is used, easily breakdown of emulsion processing, can adopt the method processing of calcium chloride, alum De-emulsification flocculent, and CODcr clearance can reach more than 92%, then passes through simple biochemical treatment, and waste water can reach secondary discharge standard.Also all there is excellent properties at aspects such as oilness, rust-preventing characteristic, cooling, antifoam performances simultaneously.
Although the cutting fluid of mentioning above-mentioned is all aqueous cutting fluid, or is soluble oil (emulsion), or is semi-synthetic cutting fluid (microemulsion), is all easy to putrid and deterioratedly because containing mineral wet goods composition, and work-ing life is short.Compared with soluble oil and semi-synthetic cutting fluid, fully synthetic cutting fluid is containing mineral oil, and its each component is all water-soluble, and diluent is transparence or translucent, thereby has good cooling and cleaning performance, and be difficult for putrid and deteriorated, long service life.
