Description
Technical field
The invention belongs to the technical field of lubricating composition, particularly relate to a kind of cutting fluid.
Background technology
Cutting fluid be a kind of be used in lathe metal cutting, in the mill course of processing, be used for the industrial type fluid of Cooling and Lubricator cutter and workpiece, cutting fluid is formed through the cooperation of science compound by multiple super strong functional auxiliary agent, possesses good cooling performance, lubricity, rustless property, oil removing cleaning function, anti-corrosion function, easily dilutable feature simultaneously.And possess nontoxic, tasteless, non-corrosive to human body, to equipment not burn into features such as environment do not pollute.
Cutting fluid becoming used cutting liquid after fully using, and the processing mode of used cutting liquid is usually through after purifying treatment (breakdown of emulsion, filtration, cohesion, separation) as sewage discharge.But the effective constituent still containing cutting fluid in used cutting liquid, is not used used cutting liquid as sewage discharge like this, the utilization ratio of cutting fluid can be made not high.Be unfavorable for the quantity discharged reducing used cutting liquid on the one hand; Be unfavorable for the manufacturing cost reducing new cutting fluid on the other hand.
Summary of the invention
The invention provides a kind of lathe cutting fluid, to solve the preparation used cutting liquid not being used for cutting fluid, cause the problem that the utilization rate of active components of cutting fluid is not high.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: a kind of lathe cutting fluid, be grouped into by the one-tenth of following mass fraction: used cutting liquid 1600-2000 part, cutting fluid 1800-2200 part, fatty acid polyglycol ester 1-3 part, nitrilotriacetic acid 1-3 part, unslaked lime 2-4 part, alcohol ether phosphoric acid ester 5-12 part, described used cutting liquid is the cutting fluid after impurity screening.
Principle of the present invention is: fatty acid polyglycol ester is a kind of nonionic surface active agent, is dissolved in Virahol, toluene, soya-bean oil, mineral oil, has the effect of emulsification, solubilising.Nitrilotriacetic acid can provide four coordinate bonds for metal ion, and its molecule is less again, and thus it has very strong complex ability, can form stable inner complex with each metal ion species.The strong keying action of itself and metal ion, metal ion inclusion is inner to sequestrant, become stable, the compound that molecular weight is larger, thus stop metal ion to work.After unslaked lime and water react, calcium hydroxide can be generated, for regulating the pH value of used cutting liquid.Alcohol ether phosphoric acid ester introduces phosphorus, when cutting, can form phosphatize phosphate coat, make metal possess certain antirust and resistance to corrosion at metallic surface.Used cutting liquid is the cutting fluid after impurity screening, and impurity screening can adopt the method for charcoal absorption, is mainly used in removing in used cutting liquid in granular metal.
Compared with prior art, the invention has the advantages that: when preparing cutting fluid, adding used cutting liquid and new cutting fluid, and adding corresponding composition, make said ratio meet the requirement of cutting fluid, the Cooling and Lubricator of cutter and workpiece can be used for.The effective constituent of cutting fluid can reasonably utilize by the present invention, not only can reduce the quantity discharged of used cutting liquid, and can reduce the manufacturing cost of new cutting fluid.
Further, cutting fluid is grouped into by the one-tenth of following mass fraction: Viscotrol C unsaturated fatty acid ester 45-55 part, fatty alcohol-polyoxyethylene ether 3-8 part, ricinolic acid 1-4 part, monoethanolamine 2-5 part, alkylamine 1-3 part, dimeracid 8-12 part, alcohol ether phosphoric acid ester 1-2 part, 3,3-methylene radical 1-4 parts.The lathe cutting fluid performance adopting above-mentioned cutting fluid to make to make is better.
Further, cutting fluid is grouped into by the one-tenth of following mass fraction: tetrasodium ethylenediamine tetraacetate 3-6 part, α-amino isopropyl alcohol 3-8 part, naphthenic base oils 35-45 part, petroleum sodium sulfonate 4-8 part, sorbitan fatty acid ester 6-9 part, 3,3-methylene radical 1-4 parts.Make the lathe cutting fluid performance that makes better by above-mentioned cutting fluid.
Further, a kind of lathe cutting fluid, the one-tenth of following mass fraction is grouped into: used cutting liquid 1600 parts, cutting fluid 1800 parts, fatty acid polyglycol ester 1 part, nitrilotriacetic acid 1 part, unslaked lime 2 parts, alcohol ether phosphoric acid ester 5 parts.This formula is the lower value of lathe cutting fluid.
Further, a kind of lathe cutting fluid, the one-tenth of following mass fraction is grouped into: used cutting liquid 2000 parts, cutting fluid 2200 parts, fatty acid polyglycol ester 3 parts, nitrilotriacetic acid 3 parts, unslaked lime 4 parts, alcohol ether phosphoric acid ester 12 parts.This formula is the higher limit of lathe cutting fluid.
Further, a kind of lathe cutting fluid, the one-tenth of following mass fraction is grouped into: used cutting liquid 1800 parts, cutting fluid 2000 parts, fatty acid polyglycol ester 2 parts, nitrilotriacetic acid 2 parts, unslaked lime 3 parts, alcohol ether phosphoric acid ester 8 parts.This formula is the intermediate value of lathe cutting fluid.
A working method for above-mentioned lathe cutting fluid, comprises the following steps:
The first step, passes through strainer filtering by used cutting liquid;
Second step, adds gac in used cutting liquid after filtration, is warming up to 60 DEG C, and is incubated one hour, then suction filtration, removes gac;
3rd step, mixes cutting fluid with used cutting liquid after step 1 processes;
4th step, in the mixing solutions of step 2, add fatty acid polyglycol ester, nitrilotriacetic acid, unslaked lime, alcohol ether phosphoric acid ester successively, after adding mentioned component, pH value is between 6-7; Specific conductivity is less than 100 μ s/cm.
The object of step one is, removes metallic particles in used cutting liquid or the larger impurity of particle.The object of step 2 is, removes by gac the non-metallic particle that in used cutting liquid, particle is less.The reason that step 3 adds new cutting fluid is, through step one and two process, although eliminate the impurity in used cutting liquid, also can effective constituent in used cutting liquid, therefore need the composition of new cutting fluid to used cutting liquid comparatively comprehensively to supplement.The object of step 4 is, the metal ion in used cutting liquid is carried out inclusion, and the pH value of regulator solution, introduces phosphorus in the solution, when cutting, can form phosphatize phosphate coat, make metal possess certain antirust and resistance to corrosion at metallic surface.With the addition of emulsifying agent, each composition is merged mutually.Step 4 is supplemented targetedly corresponding composition for the situation of used cutting liquid composition consumption.
