Abstract:
A metal-working lubricant comprises 50 to 98% of liquid polybutene obtained by polymerization of a mixture of iso- and normal-butenes and having a viscosity at 210 DEG F. of from 30 SSU to 1100 SSU, and 2 to 50% of a fatty material. An emulsifier (triethanolamine or diglycolamine) also may be present. The fatty material may be a fat or oil of animal, vegetable or marine origin, a sulphurized or oxidized derivative thereof, a fatty acid derived from said fats and oils, or a sulphurized or hydrogenated derivative thereof; in particular, hydrogenated tallow fatty acid, sperm oil wax or blown sperm oil. The compositions find application in contacting the mould surface in the continuous casting method of solidifying liquid metals, and (in mineral oil compositions) in the cold rolling of steel.ALSO:A metal working lubricant comprises 50 to 98% of liquid polybutene obtained by polymerization of a mixture of iso and normal butenes and having a viscosity at 210 DEG F. of from 30 SSU to 1100 SSU, and 2 to 50% of a fatty material.
