Definitions

  • the present invention pertains to emulsifiers, useful in metalworking fluids, as well as to metalworking fluids, containing those emulsifiers.
  • Metalworking fluids either based on petrochemical or natural oils, are well known in the art and utilized throughout the industry for a variety of processes including rolling, stamping, drawing, pickling, cutting and extruding.
  • Aqueous formulations of various oils are widely used as the rolling oil in the cold rolling of steel to provide lubrication and to cool the rolls.
  • rolling oils for example, must be capable of providing a continuous coating on the surface of the metal. Furthermore, this coating or film must have a minimum thickness and must be substantive enough to the metal so that it will be maintained at the high pressures which occur in the roll bite.
  • the rolling oil provides some measure of corrosion protection to the rolled strip and burns off cleanly during the annealing operation. Residual rolling oil must volatilize cleanly and should not leave any carbonaceous deposits or surface discoloration.
  • numerous metalworking fluids have been developed in an attempt to obtain the optimum balance of properties. Most of these variations have involved the use of different fats and oils or replacement of a portion of the fat or oil with a petroleum product, e.g. mineral oil, or a synthetic lubricant, e.g. a synthetic hydrocarbon or ester.
  • Emulsifier systems have also been widely varied and additives have been employed to enhance the characteristics of these oils.
  • emulsions are quite unstable fluids. For example, they often show tendency to coalescence resulting in an increased mean particle size, changed particle size distribution and finally in oil and/or water separation. This instability is even more pronounced when operating under varying and severe process conditions.
  • variables like make-up water quality/composition, temperature, pH, tramp oil and metal fines in the emulsion are considered important and crucial.
  • the values of these variables can vary over wide ranges, well-known to those skilled in the art. For example, water hardness values of between 0° dH (demineralized water) and 40° dH for make-up water are observed.
  • FIG. 1 is a graph displaying foam height versus time for emulsifiers of formula (I), versus a commercial standard.
  • FIG. 2 is a graph displaying foam height versus time for inventive metalworking formulations including the emulsifiers of formula (I), versus a commercial standard.

  • Such compounds can be described with the general formula RO—(CH 2 CR′—O) n (CH 2 —CH 2 —O) m —H, or more simply as RO—(PO) n -(EO) m —H.
  • R′ stands for a methyl group, i.e. those compounds contain both ethylene oxide and propylene oxide together.
  • a further preferred embodiment of the present invention pertains to the use of a blend of components according to formula (I), in which R represents in the one compound a saturated moiety, and in the other compound an unsaturated moiety.
  • the blends of saturated and unsaturated compounds according to formula (I) may vary across a broad range of weight ratio, for example the saturated compound is present in amounts from 1 to 99% by weight, and the unsaturated compound is present in amounts from 99 to 1% by weight. But, in cases when those combinations of saturated and unsaturated compounds are used, the amount of saturated compounds of formula (I) could be greater than the amount of unsaturated compounds according to formula (I). For example, the amount of the unsaturated compound is in the range from 51 to 99% by weight, and the amount of the saturated compound is from 1 to 49% by weight in a preferred embodiment of the present invention.
  • a most preferred blend according to the invention contains oleyl-(C18′) and cetyl (C14)-based compounds according to formula (I) together. These compounds may be present together in weight ratios from 99:1 to 1:99, and particularly in the ratio from 4:1 to 1:4, and most particularly in the weight ratio from 9:1 to 3:1.
