Definitions
- the subject of the present invention is use as an aqueous working fluid of compositions comprising at least one body fatty and at least one cyclodextrin.
- the two main functions sought in a cutting fluid are increasing the service life of the tool by a lubricating power and by a power of cooling, and the contribution to obtaining a good surface finish by anti-welding power.
- machining fluids are anhydrous and largely made up of fatty substances. They present generally excellent lubrication characteristics.
- aqueous fluids are preferred over whole fluids.
- Aqueous fluids fall into three categories : soluble fluids, semi-synthetic fluids and synthetic fluids.
- Soluble or emulsifiable fluids occur usually in the form of a milky emulsion.
- Semi-synthetic fluids are found under the form of a translucent micro-emulsion or pseudo-emulsion, becoming opaque in service.
- machining fluids especially aqueous
- various additives such as for example oiling agents, antiwear agents and / or agents extreme pressure.
- EP extreme pressure additives
- EP compounds are most often compounds organo-sulfur, organo-chlorine, organo-phosphorus chemicals and / or combinations of these compounds, paraffins chlorinated being the main EP additives used. Their use is however limited in practice by corrosion and toxicity risks resulting from the formation of chlorine in the presence of water.
- extreme pressure additives which they are chlorinated, sulfur or phosphorus compounds, have the major disadvantage of being polluting for the environment, which therefore causes costs of high treatment for their elimination.
- the object of the invention is to remedy the drawbacks prior art aqueous machining fluids and has for object use as an aqueous working fluid of compositions characterized by the fact that they include at least one fatty substance and at least one cyclodextrin.
- fatty substance means any oil or fat, liquid, solid or pasty at room temperature, whether original vegetable, animal, mineral or synthetic, whether used as is or chemically modified, as well as any extract from one of these fatty substances such as for example phytosterols, cholesterol, undecylenic acid, or still a mixture of several of these compounds.
- said fatty substance is an ester or a fatty acid salt or a mixture of fatty acid esters and / or fatty acid salts of vegetable origin.
- cyclodextrin alpha, beta or gamma cyclodextrin, or mixtures thereof, as well as derivatives of these cyclodextrins. It may be recalled that ⁇ , ⁇ and ⁇ cyclodextrin are macrocycles containing respectively six, seven and eight glucose patterns.
- derivative should be understood as including any macrocycle as it has just been defined, in which at least one of the glucose units is substituted, at least in one place, by a group or a molecule which can be of size and very diverse functionality, such as grouping alkylated or hydroxyalkylated, and in particular a group hydroxypropyl, or a mono- or di-saccharide molecule such as a maltose, glucose, fructose or sucrose.
- derivative also includes "polymers” of cyclodextrins obtained for example by reaction cyclodextrins with polyfunctional reagents.
- ⁇ -cyclodextrin hereinafter designated BCD
- BCD ⁇ -cyclodextrin
- composition used according to the invention as an aqueous working fluid, preferably from 30 to 99% and more preferably still from 50 to 95% of body fatty, and from 0.5 to 95%, preferably from 1 to 70% and more preferably still from 5 to 50% of cyclodextrin, these percentages being expressed in dry / dry weight.
- composition is preferably presented in a concentrated form, to make storage easier and its transport to the places of use.
- the amount of water present in the composition does not constitute a particularly important parameter and we can even consider preparing the composition according to the invention in the absence of water, the water necessary for the constitution of aqueous machining fluids themselves only added when of the step of preparing said fluids.
- the composition used in accordance with the invention in the form of a homogeneous suspension or dispersion, with a certain amount of water, usually between 22 and 70% by weight, preferably between 30 and 60% by weight.
- machining fluids such as corrosion, thickening agents, defoaming agents, wetting agents, bactericidal agents and / or fungicides and extreme pressure agents can be added, totally or partially, from the preparation of the compositions, or they can be incorporated during the final preparation of aqueous machining fluids.
- aqueous machining fluids used in accordance with the invention are prepared from the compositions described above.
- This preparation is carried out by placing under vigorous agitation of the composition for machining fluid, most often after addition of water and if necessary after addition of certain adjuvants if these are not already included in said composition.
- Time agitation is chosen so as to allow obtaining emulsions.
- the amount of water present in machining fluids does not constitute a particularly important parameter.
- the working fluids contain sufficient of water to be able to emulsify the material fatty by the compound cyclodextrin.
- the amount of water present in the machining fluids varies depending on the operation at which these fluids are intended for, cutting operations requiring less concentrated fluids than operations deformation for example. Most generally, the amount of water present in the machining fluids according to the invention is between 22% and 99%, preferably between 30 and 99% and more preferably still between 35% and 98%.
- One of the advantages of using, according to the invention of a cyclodextrin in the constitution of aqueous machining fluids lies in the fact that it is possible to obtain a substantially lubricating capacity equivalent, while slightly decreasing the amount of fat and correspondingly increasing the amount of water.
- machining fluids aqueous materials used in accordance with the invention are in the form of a metastable emulsion whose technical performance are however remarkable and whose reprocessing, after use, is greatly facilitated.
- compositions used as machining fluids in accordance with the invention are perfectly bacteriologically stable without it be obligatory to use the presence of agents bactericides and / or fungicides, unlike aqueous machining fluids and art compositions prior. This is obviously another advantage, not predictable, conferred by the present invention. The risk of skin irritation and allergies often caused by contact with such agents are further, and as a result, greatly reduced or even eliminated.
- aqueous machining fluid of the composition comprising at least one gas body and at least one cyclodextrin conform to the invention lies in the fact that it allows significantly reduce the amount of extreme pressure agents present.
- DE-A-550 871 describes the use watery emulsions of machining fluid, more particularly it describes a rust inhibition process on metals by the use of oils or materials cutting fat in highly diluted aqueous emulsions, characterized by the fact that before using the cutting oils or fats, add to water used for the emulsion, an original colloidal substance vegetable or animal.
- cyclodextrins have already been proposed in whole fluids such as lubricant compositions and in particular cutting oils; so the US Patent No. 3,314,884 granted to MOBIL OIL CORP. claims their use in order to improve performance of these compositions thanks to their complexing properties vis-à-vis the chemical additives introduced therein.
- the role of cyclodextrins is to protect complexed additives against anticipated degradation (oxidative or bacteriological) and constitute a means of control their release.
- metastable or even unstable emulsions containing a compound cyclodextrin as an emulsifier can be used as an aqueous working fluid and respond quite fully satisfies the requirements of this application, such as in particular the maintenance of properties, in lubricants, at operating temperatures which can reach 700 ° C at tool and workpiece level machined during the machining operation.
- cyclodextrin is harmless total for the manipulator, unlike the emulsifiers conventionally used, and finally use as a fluid machining of compositions comprising at least one fatty substance and at least a cyclodextrin according to the invention proves to be particularly advantageous in difficult machining conditions as they allow to be exonerated in whole or in part from the presence extreme pressure agents whose harmful effects for the environment are notorious.
- aqueous machining fluids used according to the invention are prepared using a simple method that requires no expensive and / or delicate apparatus or technical means, this which constitutes another advantage of the invention.
- parts in particular metal, which consist of machining these parts with simultaneous watering of the active part of the tool by an aqueous machining fluid containing at least one fatty substance and at least one cyclodextrin, then recover the fluid at the end of the operation machining, leave it to rest for the time necessary to that there is separation of the phases, to recover each of the phases, to filter them in order to remove the impurities in suspension and finally to recycle them according to a treatment of appropriate regeneration.
- compositions comprising at least one gas body and at least one cyclodextrin allows both better refrigeration, better lubrication under conditions difficult machining, recycling costs reduced by the absence, or at least the presence in quantity less significant, sulfur, chlorinated or phosphorous, and has good resistance to development bacterial or fungal.
- cyclodextrins being derived from materials renewable plants, namely starchy materials, their biodegradability and non-toxicity make them products perfectly tolerated by the environment.
- an original fatty substance plant or animal use according to the invention has a biodegradable character.
- Use according to the invention finds its application in all machining operations, in particular metals, whether cutting (bar turning operations, milling %) or deformation (stamping, drawing, rolling ). It can also be applied to temporary protection operations on the surfaces of objects such as auto parts, piping, frames aluminum, molded articles and others, which consist basically apply a protective coating to them usually in the form of a film or film which can be disposed of at the time of sale or immediately before use.
- compositions are prepared as follows :
- compositions thus obtained are presented under the form of concentrated emulsions. From these compositions, two machining fluids A and B are prepared, by dilution with 70 liters of demineralized water for each of the two fluids.
- the surface tension is then, the case if necessary, adjusted by adding a tall oil fatty acid saponified with a triethanolamine, so as to obtain a surface tension of about 35 mN / m.
- the cutting fluid which will be taken as reference below (REF 1) is an emulsifiable mineral oil which forms with water a milky emulsion stable over time. She is additive anticorrosion, antirust, antifoam and extreme pressure. Its dry matter is 3%.
- Machining fluids A and B are tested in bar turning.
- Operations carried out on a production of 6 hours are as follows: drilling, turning, tapping, chamfer drive, groove drive (1.5 mm), thread, sinking trapezoidal groove and cutting.
- tolerance criteria are preset regarding the diameter, the thread pitch, the coaxiality, roughness or visual appearance of the parts.
- the lifespan by evaluation of the collapse of the cutting edge and wear are measured.
- the fragmentation is evaluated; we judge thus, in their appearance, the quality of lubrication and refrigeration. Indeed, depending on whether they are straight and long, tangled, in the form of a large diameter helix, or small diameter propeller, straight and short, arched, spiral, needle or grain, the quality of the parts will be different.
- Machined steel is weakly structural steel ally 18 CD4U, supplied by ASCOMETAL.
- the criterion studied was the roughness of the machined parts.
- Roughness is measured using a device PERTHEN M4P surface finish.
- Chips obtained with machining fluids A and B are of at least equivalent quality and often better than that of the shavings obtained with the machining fluid of the prior art.
- Table VIII highlights the number of parts machined until the death of one of the tools, as well as the nature of the faulty tool and gives a classification in lackluster performance of machining fluids A and B with respect to the reference machining fluid.
- fluid B comparatively machining fluid according to the prior art, allows productivity gains in drilling, tapping, 1.5 throat driving and part cutting, and performance equivalent in stock removal.
- Machining fluids according to the invention have the advantage present spontaneous phase separation after storage for a few days.
- fluid B the composition of which has already been given in table I
- fluid C the composition of which is as follows: % in weight ENERPAR mineral oil (BP) 4.07 ⁇ -cyclodextrin KLEPTOSE (ROQUETTE FRERES) 1 LUBRIZOL 5329 (LUBRIZOL) 1.05 Xanthan gum 0.09 Water 93.79
- the curve relating to the fluid C shows that after 20 days at rest, the aqueous phase represents 50% of the volume of this fluid.
- the concentrated supernatant emulsion is then broken according to known means: it can be a chemical means (emulsion breaker such as sulfuric acid), mechanical, enzymatic and / or thermal.
- emulsion breaker such as sulfuric acid
- mechanical, enzymatic and / or thermal can be a chemical means (emulsion breaker such as sulfuric acid), mechanical, enzymatic and / or thermal.
- the supernatant emulsions of fluids B and C were added 1.5% of pure sulfuric acid, then heated to 118 ° C for 15 minutes and finally subjected to a centrifugal action (SORVALL RC5C centrifuge - 1200 m / s2), which allowed total recovery of the oil.
- the oil thus recovered can possibly be reused in the same application.
- the aqueous machining fluid taken as reference is obtained by diluting an adjuvanted paraffinic oil extreme pressure and containing a preservative. Her dry matter is 5% (REF 2).
- the number of aerobic germs, mold, yeast, anaerobic bacteria and anaerobic bacteria sulfatoréductrices was evaluated. The values are gathered in table X.
- This table shows the good stability vis-à-vis the microorganisms of the machining fluids A and B.
- New machining fluids according to the invention are prepared in a manner identical to that used for fluids A and B.
- aqueous machining fluids B, D and F which do not are not additive extreme pressure, have performances perfectly similar to those of cutting fluids according to the prior art REF 1 and REF 3 with extreme pressure additives.
