Plunger water-soluble lubricant for die-casting

摘要

A plunger water-soluble lubricant for die-casting includes a component (a) being one or more than one of compounds selected from the group consisting of a mineral oil, a synthetic hydrocarbon, a grease, and a fatty acid ester; a component (b) being one or more than one of compounds selected from the group consisting of an alkali metal salt of a higher fatty acid and an alkali metal salt of an aliphatic hydroxy acid; a component (c) being one or more than one of compounds selected from the group consisting of an alkali metal salt of a synthetic sulfonic acid and an alkali metal salt of a petroleum sulfonic acid; particulate silica; and water. This water-soluble lubricant for die-casting has a low burnability (flammability), and exerts an excellent lubricating property without lowering the productivity and worsening the working environment.

主权项

1. A water-soluble lubricant, comprising:
0.1 to 20 weight % with respect to a total weight of said lubricant of a component (a) being one or more than one of compounds selected from the group consisting of a mineral oil, a synthetic hydrocarbon, a grease, and a fatty acid ester; 2 to 24 weight % with respect to said total weight of said lubricant of a component (b) being one or more than one of compounds selected from the group consisting of an alkali metal salt of a higher fatty acid and an alkali metal salt of an aliphatic hydroxy acid; 0.1 to 20 weight % with respect to said total weight of said lubricant of a component (c) being one or more than one of compounds selected from the group consisting of an alkali metal salt of a synthetic sulfonic acid and an alkali metal salt of a petroleum sulfonic acid; 0.1 to 5 weight % with respect to said total weight of said lubricant of particulate silica; and at least 50 weight % with respect to said total weight of said lubricant of water.
