  • metal working fluids may have some disadvantages which are obviated or minimized by the metal working fluid of the present invention.
  • the metal working composition of the present invention may be synthesized by merely mixing the components together.
  • metal working fluids do not require that the components chemically react with each other, many compositions require a high proportion of relatively more expensive active ingredients to relatively less expensive ingredients, thereby increasing the cost of the metal-working composition.
  • Some metal working compositions may have the further disadvantage of requiring components which pose a potential health hazard to persons using them.
  • many metal working fluids used in the past contained nitrites, which have recently been recognized as participating in the conversion of certain chemical substances into carcinogens.
  • the United States Environmental Protection Agency recently promulgated a rule prohibiting the addition of nitrosating agents, such as nitrites, to triethanolamine salts of substituted organic acids when the mixture is to be used in metal working fluids due to the carcinogenic propensity of such materials demonstrated in animal studies (Federal Register, Vo. 49 No. 116, June 14,1984, Rules and Regulations). This difficulty is avoided by the present invention, which exhibits good metal working properties without containing nitrosating agents.

  • salts consistent with this embodiment include iron phosphates, ammonium sulfates and sodium nitrates.
  • the composition of the present invention provides a metal-working composition in which time-consuming and costly component preparation may be avoided, and yet achieve excellent cooling, high lubricity, and extreme-pressure properties. Further, the composition of the present invention may exhibit high thermal and hydrolytic stability, while inhibiting the development of rust on the workpiece and equipment. Some formulations, such as those containing N-methyl ethanolamine as some or all of the alkanolamine component, may also exhibit a lowered susceptibility to the growth of mold and bacteria.
  • the ratio of the ingredients for optimum performance in a particular application, such as extreme-pressure properties, can be adjusted as needed. It is preferred, however, that the ratio by weight of the alkanolamine (b) to the amine (a) be 20:1 to 0.05:1, more preferably 10:1 1 to 0.1:1, and most preferably 7:1 to 0.5: 1. When the ratio of the alkanolamine (b) to the amine (a) is 20:1 to 0.05:1, it is preferred that the ratio by weight of component (c) to the amine (a) be 3:1 to 0.01:1, more preferably 1.5:1 to 0.1:1.
  • composition of the present invention usually will be stored and shipped in a relatively concentrated form. Although this concentrate may contain no significant quantities of water, the composition usually will be shipped and stored as an aqueous solution which contains 10-60% by weight, and preferably 20-50% by weight, of (a), (b) and (c) combined.
  • composition of the present invention may be used in a concentrated form, due to the fact that a significant portion of the cost of a lubricating composition generally is for the "active" components rather than the carrier medium, e.g. water or oil, it is generally preferred that the amount of metal-working composition in a lubricant or coolant be as low as practically possible.
  • the composition of the present invention may be used in the form of highly dilute aqueous solutions without adversely affecting the lubricity, extreme-pressure or anti-wear properties of the invention.
  • the composition is an aqueous solution which includes at least 85% by weight water, based on the total weight of the solution, and 0.1 to 15%, more preferably 0.5 to 10% by weight, and most preferably 0.5 to 5%, by total weight of (a), (b) and (c), although, as is known to those skilled in the art, the appropriate concentration will vary depending on the application.
  • the pH of the composition be 7.5 to 10.5, more preferably 8 to 9.5, in order to minimize the corrosive effects of the composition on the workpiece.
  • pH's in the preferred ranges may be attained by adjusting the proportions of the various components to each other, and/or by adding other components, such as acids or bases, to maintain the proper pH balance.
  • Other components may also be added to assist in solubilizing the composition in water, although these are not usually necessary.
  • Other known additives such as biocides, dyes, perfumes, antifoam compounds, crystal growth modifiers, scale inhibitors and chelating agents for hard water use may also be included.
  • Examples 1-28 illustrate the testing of various fluids to determine their load carrying properties by determining their maximum load to failure. Testing reported in Tables I and II was performed according to ASTM No. D 3233-73, "Standard Methods for Measurement of Extreme Pressure Properties of Fluid Lubricants (Falex Methods)".
  • the lubricating fluids in these examples are fluids formed by placing the components indicated in deionized water. Amounts indicated are weight percent, based upon the total weight of the fluid.
  • the term DEA indicates diethanolamine and TEA indicates triethanolamine.
  • Examples 1-7 represent various formulations of the preferred embodiment of the invention, wherein the solubilizing component is the inorganic acid, H 3 PO 4 .
  • the composition of the present invention is not limited to inorganic acids or H 3 P0 4 in particular may be seen from Examples 21-28.
  • Comparative Examples C8-C12 represent testing of various commercially available metal-working compositions as a basis for comparing the composition of the present invention.
  • Cim Cool 400 is a proprietary metal-working concentrate, for heavy machinery and grinding, of Cincinnati Milacron; Do-All is #470 soluble oil of Do-All Finishing Company; Antara HR-719 is a proprietary metal-working lubricant of GAF Corp.; E-Cool is a proprietary fluid from Henry E. Sanson & Sons, Inc., and Clear Mint is a concentrated, synthetic cutting lubricant, coolant and rust inhibitor from Amitron Products, Inc.
  • Comparative Examples C13-C20 represent testing of various components useful in making the composition of the present invention.
  • H 3 P0 4 is 85 wt.% phosphoric acid aqueous solution.
  • PEGAMEEN is a Trademark of Borg-Warner Chemicals, Inc. used in conjunction with amines compounds containing a relatively large hydrocarbyl group and useful as amine (a) in the compositions of the present invention, according to the general formula discussed above, wherein R 1 is a hydroxyalkyl or hydroxyl-terminated poly(oxyalkylene) moiety.
  • the numerical portion of the PEGAMEEN designation, such as T-7, T-15 and T-25 indicates the average value of the total number of oxyalkylene units in the large amine compound. Consequently, T-7 indicates an average value of 7, T-15 indicates an average value of 15, and T-25 indicates an average value of 25.
  • R 2 is a tallow moiety.
  • the results of Examples 1-C20 are reported in Table I.
  • Examples 21-28 illustrate the effect of various inorganic acids, such as H 2 S0 4 and boric oxide, which hydrolyzes to boric acid in the presence of water, carboxylic acids, and salts on the extreme-pressure test results conducted as described above.
  • a series of compositions were prepared containing 0.4% by weight of Pegameen T-7, 2.0% by weight triethanolamine and various concentrations of different acids or salts.
  • the acids or salts, their concentration and the extreme-pressure test results are indicated in Table II.
  • alkanolamine may be N-methyl ethanolamine without degrading the metal working properties of the composition of the present invention.
