Aqueous metal-working lubricant containing polyoxypropylene-polyoxyethylene-polyoxypropylene block copolymers.

摘要

An aqueous metalworking lubricant composition comprising a water-soluble mixture of polyoxypropylene-polyoxyethylene-polyoxypropylene block copolymers, a water-soluble carboxylic acid, a water-soluble alkanolamine and water. A preferred lubricant composition also comprises an antifoam agent. The lubricant composition is suitable for both cold rolling and hot rolling of metals such as aluminum and aluminum alloys. A method of metalworking includes applying said lubricant composition during operations such as hot or cold rolling.
