Abstract

Abstract A water emulsifiable lubricant and coolant for the cold forming of metal, as in the forming and stamping of sheet metal parts and in the drawing of wire. The composition has superior lubricant and coolant properties and also imparts some degree of corrosion protection for the part after forming. The composition contains oleic acid, an ethanolamine, a mixture of mineral oils or a mixture of mineral oil with a wax, and a mixture of emulsifiers. The emulsion is stable at various strengths and at pH values ranging from 7.0 to 9.5, thus being useful with various plated or coated metals, as well as with uncoated metals.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 114 words
A lubricant and coolant composition for application as an aqueous emulsion to a metal surface prior to cold forming, consisting essentially of: about 47 parts by weight oleic acid, about 12 parts by weight of an ethanolamine, about 23 parts by weight of a heavy mineral oil, about 36 parts by weight of dialkylphenoxypoly(ethyleneoxy)ethanol, about 34 parts by weight of a sodium salt of an alkylpoly oxyethylene phosphate ester, about 98 parts by weight of a light lubricating ingredient selected from the group consisting of a light mineral oil, paraffin wax and an oxazoline wax, and about 750 parts by weight water, the emulsion having a pH ranging from about 7 to about 9.5.
Claim 2
Dependent Claim 114 words
A lubricant and coolant composition for application as an aqueous emulsion to a metal surface prior to cold forming, consisting essentially of: about 47 parts by weight oleic acid, about 12 parts by weight of an ethanolamine, about 23 parts by weight of a heavy mineral oil, about 36 parts by weight of dialkylphenoxypoly(ethyleneoxy)ethanol, about 34 parts by weight of a sodium salt of an alkylpoly oxyethylene phosphate ester, about 98 parts by weight of a light lubricating ingredient selected from the group consisting of a light mineral oil, paraffin wax and an oxazoline wax, and about 750 parts by weight water, the emulsion having a pH ranging from about 7 to about 9.5.
Claim 3
Dependent Claim 25 words
A composition as defined in claim 1, wherein the ethanolamine is monoethanolamine and the emulsion has a pH of from about 8.8 to about 9.5.
Claim 4
Dependent Claim 25 words
A composition as defined in claim 1, wherein the ethanolamine is triethanolamine and the emulsion has a pH ranging from about 7 to about 8.
Claim 5
Independent Claim 123 words
The method of cold-forming a metal which comprises applying thereto, immediately prior to cold-forming, an aqueous emulsion consisting essentially of: about 47 parts by weight oleic acid, about 12 parts by weight of an ethanolamine, about 23 parts by weight of a heavy mineral oil, about 36 parts by weight of dialkylphenoxypoly (ethyleneoxy) ethanol about 34 parts by weight of a sodium salt of an alkylpoly oxyethylene phosphate ester, about 98 parts by weight of a light lubricating ingredient selected from the group consisting of a light mineral oil, paraffin wax and an oxazoline wax, and about 750 parts by weight water, the emulsion having a pH ranging from about 7 to about 9.5; and cold-forming the blank while wet with said emulsion.
Claim 6
Independent Claim 123 words
The method of cold-forming a metal which comprises applying thereto, immediately prior to cold-forming, an aqueous emulsion consisting essentially of: about 47 parts by weight oleic acid, about 12 parts by weight of an ethanolamine, about 23 parts by weight of a heavy mineral oil, about 36 parts by weight of dialkylphenoxypoly (ethyleneoxy) ethanol about 34 parts by weight of a sodium salt of an alkylpoly oxyethylene phosphate ester, about 98 parts by weight of a light lubricating ingredient selected from the group consisting of a light mineral oil, paraffin wax and an oxazoline wax, and about 750 parts by weight water, the emulsion having a pH ranging from about 7 to about 9.5; and cold-forming the blank while wet with said emulsion.
