  • metal-working fluids related in certain aspects to the metal-working fluid of the present invention, are disclosed by U.S. Patent Nos. 4,172,802 to Rieder, 4,177,154 to Chakrabarti, and 3,933,658 to Beiswanger et al.
  • a phosphoral tris(diethanolamide) additive is disclosed for water-based and ethylene-glycol based hydraulic fluids and lubricants in Wear, 50 (1978) 365-369, Ludomir, Tokarzewski, Zakrzew- ski, Wachowicz and Szczepaniak.
  • Another phosphorus based metal-working composition is disclosed in Polish Patent Document No. 116,962 to Szczepaniak et al.
  • 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 carcenogenic propensity of such materials demonstrated in animal studies (Federal Register, Vol. 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.
  • the present invention is a water-soluble, metal-working composition which includes a relatively large alkoxylated amine, an alkanol amine and an acid-derived compound, wherein the large alkoxylated amine is generally described by the formula: Consistent with this formula, R 1 is selected from the group consisting of hydrogen, hydrocarbyl moieties, alkoxy moieties and polyalkoxy moieties, R 2 is selected from the group consisting of C 7 and larger hydrocarbyl moieties, and R 3 is selected from the group consisting of alkoxy moieties and polyalkoxy moieties.
  • the alkanol amine may generally be described by the formula:
  • R 4 is selected from the group consistent of hydrogen, C 1 -C 6 hydrocarbyl moieties, and monomeric and polymeric alkoxy moieties consisting essentially of alkoxy units selected from the group consisting of ethoxy, 2-propoxy, 2-butoxy and mixtures thereof.
  • R 5 is selected from the group consisting of C 1 -C 6 hydrocarbyl moieties, and monomeric and polymeric alkoxy moieties consisting essentially of alkoxy units selected from the group consisting of ethoxy, 2-propoxy, 2-butoxy and mixtures thereof.
  • R 6 is selected from the group consisting of monomeric and polymeric alkoxy moieties consisting essentially of alkoxy units selected from the group consisting of ethoxy, 2-propoxy, 2-butoxy and mixtures thereof.
  • R 4 , R 5 and R 6 are additionally selected so that the alkanol amine contains a total of 6 or fewer alkoxy units.
  • the acid-derived compound included in the present invention is selected from the group consisting of inorganic acids, organic acids, and salts thereof.
  • the present invention is a water-soluble, metal-working composition
  • a relatively large alkoxylated amine is a relatively large amine which may be generally described by the formula:
  • R 2 is a relatively large hydrocarbon group selected from the group consisting C 7 and larger hydrocarbyl moieties.
  • hydrocarbyl moieties are generally alkyl or alkenyl in character, but may be an aryl moiety such as benzyl, methyl benzyl or dimethoxy benzyl, and alkyl phenyls such as nonyl phenyl.
  • alkyl and alkenyl moieties are preferred.
  • Polyalkoxy groups are not included.
  • Stearyl, oleyl, soya, coco and tallow moieties are most preferred.
  • R 1 is selected from the group consisting of hydrogen, hydrocarbyl moieties, alkoxy moieties and polyalkoxy moieties.
  • the hydrocarbyl moieties may be aryl, alkyl or alkenyl in character, such as phenyl, stearyl, oleyl, soya, coco and tallow. Alkyl or alkenyl groups are preferred.
  • R 1 may be selected independent of R 2 , when R 1 is hydrocarbyl it is preferred that R 1 be the same as R 2 due to the relative cost efficiency of preparing the alkoxylated amine when, instead of being different hydrocarbyl moieties, both R1 and R2 are the same.
  • R1 is an alkoxy or a polyalkoxy moiety, consistent with those defined for R 3 .
  • R 3 may only be selected from the group consisting of alkoxy and polyalkoxy moieties.
  • these alkoxy and polyalkoxy moieties consist essentially of alkoxy units generally described by the following formula.
  • the oxygen of alkoxy moieties and the terminal oxygen of polyalkoxy moieties is bonded to hydrogen, not shown in the above formula, to form a terminal hydroxy group.
  • R 7 is selected from the group consisting of hydrogen and C 1 -C 28 hydrocarbyl moieties, such as alkyl groups like methyl, ethyl and propyl. More preferably, R 7 is hydrogen, methyl or ethyl, so that the alkoxy unit is an ethoxy, 2-propoxy or 2-butoxy unit, respectively. Ethoxy and propoxy units, wherein R 7 is hydrogen or methyl, respectively, are even more preferred.
  • R 3 may be a polyalkoxy moiety consisting of a mixture of different alkoxy units, such as a mixture of ethoxy units and propoxy units, it is more preferred that R 3 be homogenous. Hydroxy ethyl and homogenous polyethoxy moieties are most preferred.
  • R 1 may be selected independently from R 3 , when R 1 is an alkoxy or polyalkoxy moiety, it is preferred that R 1 consist essentially of at least some of the same alkoxy units as R 3 in order to simplify preparation of the tertiary alkoxylated amine.

  • R 1 when R 3 is a polyethoxy moiety, it is preferred that R 1 be hydroxy ethyl, polyethoxy or a mixed polyalkoxy moiety of ethoxy units and other alkoxy units. Most preferably, however, both R 1 and R 3 consist essentially of the same kind of alkoxy units.
  • R 1 and R 3 are chosen such that the total number of alkoxy units in the large alkoxylated amine is equal to 2 to about 35.
  • the total number of alkoxy groups may be equal to 2 when each of R 1 and R 3 is hydroxy ethyl, or when R 3 is a polyethoxy moiety consisting of 2 ethoxy units and R 1 is hydrogen or a hydrocarbyl moiety such as tallow.
  • the total number of alkoxy units in said large alkoxylated amine is equal to about 5 to about 20, such as where R 3 is a polyethoxy moiety consisting of three ethoxy units, and R 1 is a polyethoxy moiety consisting of two ethoxy units.

  • R 4 is selected from the group consisting of hydrogen, C 1 -C 6 hydrocarbyl moieties such as methyl, phenyl, ethyl, propyl and butyl, and monomeric and polymeric alkoxy moieties.
  • R 4 is a monomeric or polymeric alkoxy moiety, the alkoxy moiety consists essentially of alkoxy units selected from the group consisting of ethoxy, 2-propoxy, 2-butoxy and mixtures thereof.
  • R 4 when R 4 is a monomeric alkoxy moiety, R 4 is selected from the group consisting of hydroxy ethyl(HO-CH 2 CH 2 -), 2-hydroxy propyl(CH 3 CH(OH) CH 2 ), and 2-hydroxy butyl(CH 3 CH 2 CH(OH)CH Z -) moieties.
  • R 4 may be a polymeric alkoxy moiety, such as polyethoxy(HOCH2CH2OCH2-CH2-) or polypropoxy (CH 3 CH(OH)-CH 2 OCH(CH 3 )CH 2 -),
  • R 4 preferably is a simple alkoxy moiety, such as hydroxy ethyl or 2-hydroxy propyl, a simple hydrocarbyl such as methyl, ethyl, or hydrogen, such as in dimethyl ethanol amine, N-phenyl ethanol amine, and N,N-diethyl ethanol amine. Hydroxy ethyl and hydrogen are most preferred, such as when the alkanol amine is triethanol amine, diethanol amine or N-methyl ethanol amine.
  • R S may be selected from the group consisting of C 1 -C 6 hydrocarbyl moieties, as discussed above for R 4 , and monomeric and polymeric alkoxy moieties which consist essentially of alkoxy units selected from the group consisting of ethoxy, 2-propoxy, 2-butoxy and mixtures thereof, as discussed above for R 4 .
  • R 5 may not be hydrogen. Consequently, although the alkanol amine may be a secondary or tertiary amine, the alkanol amine may not be a primary amine.
  • R is methyl, as in N-methyl ethanol amine or dimethyl ethanol amine, or hydroxy ethyl, as in diethanol amine or triethanol amine.
  • R 6 may be a monomeric or polymeric alkoxy moiety consisting essentially of alkoxy units selected from the group consisting of ethoxy, 2-propoxy, 2-butoxy, and mixtures thereof, as discussed above for R 4 .

  • each of R 41 R 5 and R 6 may be a polymeric alkoxy group
  • the alkanol amine may contain no more than a total of 6 alkoxy units. However, fewer than 6 alkoxy units are preferred, such as in triethanol amine, diethanol amine and N-methyl ethanol amine, wherein the total number of alkoxy units is equal to or less than 3.
  • the composition of the present invention also contains an acid-derived compound.
  • This acid-derived compound may be an organic acid, an inorganic acid or a salt derived from an organic or inorganic acid by the replacement of an acidic hydrogen by another appropriate cation.
  • Preferred organic acid-derived compounds include acetic acid, propionic acid, butyric acid, formic acid, oxalic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, benzoic acid, suberic acid, azelaic acid, para-toluene sulfonic acid, sebacic acid, and amino acids such as alanine, leucine, phenylalanine, glycine, tyrosine, serine, aspartic acid and glutamic acid.
  • the acid-derived compound is an inorganic acid, with phosphoric acid, nitric acid and sulfuric acid being preferred. Boric acid is not preferred. Phosphoric acid is most preferred.
  • the acid-derived compound may be a salt of an organic or inorganic acid, and preferably is a salt of the preferred acids discussed above.
  • the acid-derived compound is a salt, it is preferred that the acid-derived compound be a Group VIII metal, alkaline metal, alkaline earth metal or amine salt.
  • 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 ethanol amine as some or all of the alkanol amine 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 alkanol amine to the relatively large alkoxylated amine be about 20:1 to about 0.0.5:1. More preferably, however, the ratio by weight of the alkanol amine to the large alkoxylated amine is about 10:1 to about 0.1:1, with a ratio of about 7:1 to about 0.5:1 being most preferred.
  • the ratio of the alkanol amine to the relatively large alkoxylated amine is about 20:1 to about 0.05:1, it is preferred that the ratio by weight of the acid-derived compound to the large alkoxylated amine be about 3:1 to about 0.01:1. Ratios of acid-derived compound to large alkoxylated amine of about 1.5:1 to about 0.1:1, however, are more preferred.
  • the 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 the relatively large alkoxylated amine, the alkanol amine and the acid-derived compound 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 about 0.1 1 to 15% by weight of the combined large alkoxylated amine, alkanol amine and the acid-derived compound, although, as is known to those skilled in the art, the appropriate concentration will vary depending on the application. More preferably, however, the large alkoxylated amine, the alkanol amine and the acid-derived compound together constitute about 0.5 to about 10% by weight of the solution, with about 0.5 to 5% being most preferred.
  • the pH of the composition be equal to about 7.5 to about 10.5 in order to minimize the corrosive effects of the composition on the workpiece; pH's in the range of about 8 to about 9.5 are more preferred. Consistent with the invention, 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 diethanol amine and TEA indicates triethanol amine.
  • Examples 1-7 represent various formulations of the preferred embodiment of the invention, wherein the solubilizing component is the inorganic acid, H 3 P0 4 .
  • the composition of the present invention is not limited to inorganic acids or H 3 PO 4 in particular may be seen from Examples 21-28.
