Description
DESCRIPCIONDESCRIPTION
Composicion para la lubricacion en cantidad mmima y su usoComposition for lubrication in minimum quantity and its use
La invencion se refiere a una composicion de lubricante para la lubricacion en cantidad mmima en el tratamiento de metales y el uso de la composicion de lubricante para ello.The invention relates to a lubricant composition for lubrication in minimal amount in the treatment of metals and the use of the lubricant composition therefor.
En los procesos de tratamiento de metales se diferencia entre un tratamiento en humedo habitual, en el que la herramienta de mecanizacion se inunda con un lubricante refrigerante, y el tratamiento en seco sin lubricante, en el que el calor que se origina en el proceso de mecanizacion se disipa principalmente en la viruta, herramienta y pieza de trabajo. Mientras que el tratamiento en seco prescinde del lubricante, el calor que fluye en la pieza de trabajo puede influir de forma desventajosa en la exactitud del componente, tambien puede desgastar antes la herramienta debido a la solicitacion termica elevada. Los lubricantes refrigerantes usados en el tratamiento en seco se ocupan en primer lugar de la refrigeracion, lubricacion y el transporte de virutas, no obstante, simultaneamente tienen influencia en los tiempos muertos en el proceso de produccion debido a la recogida, procesado y eliminacion de los lubricantes refrigerantes, y por consiguiente tambien en los costes para su compra, procesamiento y eliminacion. Ademas, se debe prestar atencion a la proteccion de la salud y del medio ambiente.In the metal treatment processes, there is a difference between a usual wet treatment, in which the machining tool is flooded with a cooling lubricant, and the dry treatment without lubricant, in which the heat that originates in the process of Machining is mainly dissipated in the chip, tool and work piece. While the dry treatment dispenses with the lubricant, the heat flowing in the work piece can have a disadvantageous influence on the accuracy of the component, it can also wear out the tool before due to the high thermal stress. The refrigerant lubricants used in the dry treatment are primarily concerned with the refrigeration, lubrication and transport of chips, however, simultaneously have influence on the downtime in the production process due to the collection, processing and disposal of the refrigerant lubricants, and consequently also in the costs for its purchase, processing and elimination. In addition, attention must be paid to the protection of health and the environment.
La lubricacion en cantidad minima (MMS) o tambien lubricacion refrigerante en cantidad minima (MMKS) constituye un termino medio entre tratamiento en humedo y tratamiento en seco. No hay definiciones exactas para las “cantidades mmimas”, segun la fuente se designan hasta 20 ml/h, 50 ml/h, 150 ml/h o a veces tambien hasta 500 ml/h como MMS - pero en todos los casos existe una clara diferencia con las cantidades habituales en el tratamiento en humedo de 30.000 hasta 60.000 ml/h o tambien claramente mas.The lubrication in minimum quantity (MMS) or also coolant lubrication in minimum quantity (MMKS) constitutes a medium term between wet treatment and dry treatment. There are no exact definitions for the "minimum quantities", depending on the source they are designated up to 20 ml / h, 50 ml / h, 150 ml / h or sometimes also up to 500 ml / h as MMS - but in all cases there is a clear difference with the usual amounts in the humid treatment from 30,000 to 60,000 ml / h or more clearly.
La lubricacion en cantidad minima ofrece respecto al tratamiento en humedo una reduccion clara de la tecnologfa de cuidado y eliminacion del lubricante refrigerante, permite vidas utiles mas elevadas y duracion de proceso reducida. Ademas, se pueden reducir los procesos siguientes para la limpieza de las piezas de trabajo y tambien de la herramienta. Dado que la lubricacion en cantidad minima significa lubricacion perdida, se usa solo lubricante nuevo, es decir, no reciclado o reutilizado, de modo que se puede prescindir de biocidas, fungicidas y otros aditivos.The lubrication in minimum quantity offers a clear reduction in the technology of care and elimination of the refrigerant lubricant, allows for higher useful lives and reduced process duration. In addition, the following processes can be reduced for cleaning the workpieces and also for the tool. Since lubrication in minimal quantity means lost lubrication, only new lubricant is used, that is, not recycled or reused, so that biocides, fungicides and other additives can be dispensed with.
Sin embargo, existen elevadas exigencias en el lubricante, que debe estar adaptado al material de la pieza de trabajo, parametros de la maquina y material de la herramienta, a fin de obtener resultados optimos.However, there are high demands on the lubricant, which must be adapted to the material of the work piece, parameters of the machine and material of the tool, in order to obtain optimal results.
En general para MMS se usan aceites esteres de sinteticos o alcoholes grasos, que estan compuestos para el rango de tratamiento deseado en referencia a la evaporacion y punto de llama. A este respecto se prefieren esteres sinteticos para los procesos de mecanizado, en los que es mas importante una lubricacion efectiva. Al usar alcoholes grasos tiene menos prioridad la lubricacion que la refrigeracion.In general for MMS synthetic oils or fatty alcohols are used, which are composed for the desired treatment range in reference to evaporation and flash point. In this respect, synthetic esters are preferred for the machining processes, in which an effective lubrication is more important. When using fatty alcohols, lubrication is less priority than refrigeration.
El documento EP 2397535 A1 da a conocer una composicion a base de un alcohol graso para el tratamiento de aluminio con lubricacion en cantidad minima. El compuesto de alcohol tiene 1 a 8 grupos hidroxilo y 2 a 27 atomos de carbono y esta contenido en la composicion en una cantidad del 16 al 100% en peso. El resto puede ser un aceite mineral o aceite sintetico, tambien aceite de ester. Para la mejora de la potencia lubricante de esta composicion se enumeran distintos aditivos que se le pueden anadir a la composicion.EP 2397535 A1 discloses a composition based on a fatty alcohol for the treatment of aluminum with lubrication in minimum quantity. The alcohol compound has 1 to 8 hydroxyl groups and 2 to 27 carbon atoms and is contained in the composition in an amount of 16 to 100% by weight. The rest can be a mineral oil or synthetic oil, also ester oil. For the improvement of the lubricating power of this composition, various additives are listed that can be added to the composition.
Se ha demostrado que en la lubricacion en cantidad minima quedan pequenas cantidades de lubricante refrigerante sobre la pieza de trabajo alrededor del punto de mecanizacion y en la herramienta. Los restos de lubricante en la pieza de trabajo pueden ayudar por un lado a evitar la corrosion en el punto de tratamiento, pero por otro lado pueden repercutir tambien de forma desventajosa en los procesos de produccion subsiguientes, como soldadura, pegado, lacado, etc. y por ello hacen necesaria eventualmente una etapa de limpieza.It has been shown that in lubrication in minimum amount small amounts of cooling lubricant remain on the workpiece around the machining point and in the tool. The remains of lubricant in the work piece can help on the one hand to prevent corrosion at the treatment point, but on the other hand they can also have a disadvantageous effect on the subsequent production processes, such as welding, gluing, lacquering, etc. and for this reason they necessarily require a cleaning stage.
Los lfquidos de tratamiento de metales mezclables con agua, que se pueden limpiar con agua, se consideran como inapropiadas para la lubricacion en cantidad minima, dado que no presentan la lubricacion necesaria para ello o el punto de llama necesario.The water-miscible metal treatment fluids, which can be cleaned with water, are considered as unsuitable for lubrication in minimum quantity, since they do not have the necessary lubrication for this or the necessary flame point.
Para la limpieza de un lubricante en base a un alcohol saturado alifatico monihfdrico C14-18, que esta configurado para el tratamiento fno de aluminio como film sobre la superficie de la pieza de trabajo, el documento WO 91/06619 describe el calentamiento de la pieza de trabajo, de modo que se evapora el lubricante.For cleaning of a lubricant based on a saturated aliphatic alcohol monihfdrico C 14 to 18, which is configured for treatment fno as aluminum film on the surface of the workpiece, WO 91/06619 describes document heating the piece of work, so that the lubricant evaporates.
El documento US 2003/0191340 A1 da a conocer un lubricante para procesos que tratan un metal.US 2003/0191340 A1 discloses a lubricant for processes treating a metal.
Partiendo de este estado de la tecnica, el objetivo de la presente invencion es proporcionar un lubricante en cantidad minima que se pueda limpiar de forma sencilla sin calentamiento y no solo de la pieza de trabajo, sino tambien de la herramienta y de la maquina-herramienta.Starting from this state of the art, the objective of the present invention is to provide a lubricant in minimum quantity that can be cleaned in a simple way without heating and not only of the workpiece, but also of the tool and the machine-tool .
Este objetivo se consigue mediante una composicion de lubricante con la caractenstica de la reivindicacion 1. This objective is achieved by a lubricant composition with the feature of claim 1.
Perfeccionamientos de la composicion de lubricante estan expuestos en las reivindicaciones dependientes.Perfections of the lubricant composition are set out in the dependent claims.
La limpieza sencilla al usar la composicion de lubricante se da a conocer con las caractensticas de la reivindicacion independiente 7.The simple cleaning when using the lubricant composition is disclosed with the features of the independent claim 7.
Una composicion de lubricante segun la invencion para la lubricacion en cantidad minima en el tratamiento de metales se compone en una parte principal de un alcohol alifatico C16-24, al que se le anade una pequena fraccion de emulsionante, de modo que el lubricante se puede emulsionar con agua. De esta manera no solo la pieza de trabajo, sino tambien la herramienta y el espacio de tratamiento (p. ej. el espacio interior de la maquina) se pueden alejar de forma sencilla de los restos de la composicion de lubricante segun la invencion gracias a la emulsion con agua. Sin embargo, se debe atender a que la composicion de lubricante no puede entrar en contacto con el agua durante el almacenamiento y suministro a la herramienta.A lubricant composition according to the invention for minimum quantity lubrication in metal treatment consists in a major portion of an aliphatic alcohol C 16 to 24, to which is added a small fraction of emulsifier, so that the lubricant You can emulsify with water. In this way, not only the workpiece, but also the tool and the treatment space (eg the internal space of the machine) can be moved away easily from the remains of the lubricant composition according to the invention thanks to the emulsion with water. However, it must be taken into account that the lubricant composition can not come into contact with the water during storage and supply to the tool.
Un emulsionante preferido es un eter alqrnlico de alcoxilato de acido glicolico, cuya fraccion en la composicion se situa en un rango de 0,05 a 5% en peso, referido al peso total de la composicion. Pero tambien es concebible que las mezclas de eter de polialquilenglicol y alcohol graso y eter alqrnlico de alcoxilato de acido glicolico se usen como emulsionantes con una fraccion de peso de 0,05 a 5% en peso, referido al peso total de la composicion. El alcohol alifatico C16-20 esta presente entonces respectivamente en una fraccion que complementa el 100% de la composicion.A preferred emulsifier is an alkene ether of glycolic acid alkoxylate, the fraction of which in the composition ranges from 0.05 to 5% by weight, based on the total weight of the composition. But it is also conceivable that the mixtures of polyalkylene glycol ether and fatty alcohol and alkylenic ether of glycolic acid alkoxylate are used as emulsifiers with a weight fraction of 0.05 to 5% by weight, based on the total weight of the composition. The C 16-20 aliphatic alcohol is then present respectively in a fraction that complements 100% of the composition.
El eter de polialquilenglicol y alcohol graso presenta la formula (I)The ether of polyalkylene glycol and fatty alcohol presents the formula (I)
R*-[(CH2CH2O)x-(CH2CH(CHa)O)y]-R1 (I).R * - [(CH2CH2O) x- (CH2CH (CHa) O) and] -R1 (I).
en donde R1 es un resto de alquilo o alquenilo alifatico C16-18, ramificado o lineal. R* puede ser un grupo hidroxilo. Las variables x e y pueden ser 0 a 10 con la suposicion de que la suma x+y es de 1 a 10. El eter de polialquilenglicol y alcohol graso, trivialmente designado tambien como alcoxilato de acido graso o alcohol graso acoxilado, solo puede ser producido a partir de unidades de oxido de etileno (y=0) o solo de unidades de oxido de propileno (X=0). Pero el eter de polialquilenglicol tambien puede contener tanto unidades de oxido de etileno, como tambien unidades de oxido de propileno. En este caso pueden variar tanto las fracciones correspondientes como tambien el orden de las unidades (p. ej. en alternancia o por bloques). Un alcohol graso puramente etoxilado no limitante a modo de ejemplo se puede basar en alcohol oleflico o cetflico: HO-(CH2CH2O)n-R con R = C18 o C16 con n=5 por ejemplo. Son concebibles sin mas desviaciones respecto al alcohol base, tipo y numero de unidades de alcoxi.wherein R1 is an alkyl or alkenyl aliphatic C 16-18 branched or linear. R * can be a hydroxyl group. The variables x and y can be 0 to 10 with the assumption that the sum x + y is from 1 to 10. The ether of polyalkylene glycol and fatty alcohol, trivially also referred to as fatty acid alkoxylate or fatty alcohol, can only be produced units of ethylene oxide (y = 0) or only of propylene oxide units (X = 0). But the polyalkylene glycol ether can also contain both ethylene oxide units, as well as propylene oxide units. In this case, the corresponding fractions as well as the order of the units can vary (eg alternation or blocks). A purely ethoxylated non-limiting fatty alcohol by way of example can be based on olefinic or cetyl alcohol: HO- (CH 2 CH 2 O) nR with R = C 18 or C 16 with n = 5 for example. They are conceivable without further deviations from the base alcohol, type and number of alkoxy units.
Para el eter de polialquilenglicol y alcohol graso se prefiere especialmente p. ej. el 1% en peso. Ventajosamente la composicion de lubricante con 1% en peso de eter de polialquilenglicol y alcohol graso presenta un balance de emulsionante apropiado con propiedades emulsionantes suficientemente buenas, sin influir a este respecto negativamente en la instalacion de limpieza (comportamiento de desemulsion). Mientras que una concentracion de emulsionante demasiado baja tiene como consecuencia una capacidad de limpieza menor en la herramienta, pieza de trabajo y espacio de la maquina, concentraciones demasiado elevadas impiden la separacion del aceite en la instalacion de limpieza.For the polyalkylene glycol ether and fatty alcohol, p is especially preferred. ex. 1% by weight. Advantageously, the lubricant composition with 1% by weight of polyalkylene glycol ether and fatty alcohol has an appropriate emulsifier balance with sufficiently good emulsifying properties, without adversely affecting the cleaning system (demulsive behavior) in this respect. While a too low concentration of emulsifier results in a lower cleaning capacity in the tool, work piece and space of the machine, too high concentrations prevent the separation of the oil in the cleaning installation.
El eter alqrnlico de alcoxilato de acido glicolico (tambien eter de acido carboxflico) presenta la formula (II)The alkene ether of glycolic acid alkoxylate (also ether of carboxylic acid) has the formula (II)
R2-O-[(CH2CH2O)x-(CH2CH(CHa)Oy]-CH2COOH (II)R2-O - [(CH2CH2O) x- (CH2CH (CHa) Oy] -CH2COOH (II)
en donde R2 es un resto de alquilo o alquenilo alifatico C6-20, ramificado o lineal. En este caso tambien entran en consideracion compuestos puramente etoxilados, puramente propoxilados o mixtos etoxilados y propoxilados, de modo que x e y estan seleccionados de 0 a 10 con la suposicion de que la suma x+y = 1 a 10.wherein R2 is an alkyl or alkenyl aliphatic C 6-20, branched or linear. In this case also purely ethoxylated, purely propoxylated or mixed ethoxylated and propoxylated compounds are considered, so that x and y are selected from 0 to 10 with the assumption that the sum x + y = 1 to 10.
Eteres alqrnlicos de alcoxilato de acido glicolico a modo de ejemplo son los eteres alqrnlicos insaturados C10-16 y C12-20 de poli(oxi-1,2-etanodiilo), a-(carboximetil)-u>-hidroxilo (p. ej. CAS n° 68954-89-2), eteres alqrnlicos insaturados C16-18 y C18 de poli(oxi-1,2-etanodiilo), a-(carboximetil)-u>-hidroxilo (p. ej.
