专利摘要

Water soluble lubricant compositions comprising alkanolamine and organic acid are improved by employing as the organic acid a partial acid amide of a dicarboxylic acid, such as mono-PRIMENE 81 R amide of succinic acid, mono-di-2-ethylhexylamide of maleic acid, mono-di-2-ethylhexylamide of methyltetrahydrophthalic acid and mono-di-2-ethylhexylamide of methylhexahydrophthalic acid as the organic acid. ......

权利要求: We claim:1. A water soluble lubricant composition comprising from about 5% to about 50% by weight of an alkanolamine, from about 1% to about 30% by weight of a partial acid amide of a succinic acid, maleic acid, a methyltetrahydrophthalic acid or a methylhexahydrophthalic acid and from about 0.5% to about 20% by weight of a polyalkylene glycol.2. The lubricant of claim 1 wherein the partial amide is a C.sub.12 to C.sub.14 alkyl amide of succinic acid.3. The lubricant of claim 1 wherein the partial amide is the mono-di-2-ethylhexylamide of maleic acid.4. The lubricant of claim 1 wherein the partial amide is the mono-di-2-ethylhexylamide of methyltetrahydrophthalic acid.5. The lubricant of claim 1 wherein the partial amide is the mono-di-2-ethylhexylamide of methylhexahydrophthalic acid.6. The lubricant of claim 1 wherein the glycol is a copolymer of ethylene and propylene oxides.7. The lubricant of claim 1 wherein the alkanolamine is diethanolamine.8. The lubricant of claim 1 wherein the alkanolamine is triethanolamine.9. The composition of claim 1 additionally containing from about 0.5% to about 5% by weight of a germicidal agent.10. The composition of claim 9 wherein the germicidal agent is a halogenated cresol.11. The composition of claim 10 wherein the halogenated cresol is para-chloro-meta-cresol, para-bromo-meta-cresol, para-fluoro-meta-cresol, 2,4-dibromo-, 2,4,5-tribromo- or 2,4,5,6-tetrabromo-meta-cresol.12. The composition of claim 9 wherein the germicidal agent is an aldehyde.13. The composition of claim 12 wherein the aldehyde is formaldehyde or formaldehyde-releasing agents.14. The composition of claim 13 wherein the formaldehyde is obtained by release from tris(hydroxymethyl) nitromethane.15. The composition of claim 9 wherein the germicidal agent is an alcohol.16. The composition of claim 9 wherein the germicidal agent is bichloride of mecury, Mercurochrome, Menthiolate, Metophen, silver nitrate, copper sulfate or an ammonium halide.17. The composition of claim 1 containing 10 to 20 parts by weight of water.
