Abstract
Provided is a lubricant composition for plastic working of a ferrous material, the lubricant composition being excellent in lubricity and releasability and not staining the work environment black. A lubricant composition for plastic working of a ferrous material is used, the lubricant composition containing (a) an alkali metal salt of an organic acid, (b) water-based resin particles, (c) a water-soluble polymer, and (d) water, the (b) water-based resin particles including particles having a particle diameter of not more than 0.1 μm in an amount of more than 5% by weight relative to a total amount of the (b) water-based resin particles.
Claims6
A lubricant composition for plastic working of a ferrous material, comprising:
- (a) an alkali metal salt of an organic acid;
- (b) water-based resin particles;
- (c) a water-soluble polymer;
- and
- (d) water,
- wherein a weight ratio of the (b) water-based resin particles to the (a) alkali metal salt of the organic acid, represented as a weight of the (b) water-based resin particles/a weight of the (a) alkali metal salt of the organic acid, is less than 10,
- the (b) water-based resin particles include particles having a particle diameter of not more than 0.1 μm in an amount of more than 5% by weight relative to a total amount of the (b) water-based resin particles,
- the (b) water-based resin particles have an average particle diameter of 0.01 μm to 0.3 μm,
- wherein the water-based resin particles are particles of at least one selected from the group consisting of an acrylic resin, a styrene-acrylic resin, a vinyl acetate-acrylic resin, a urethane resin, a urethane-acrylic resin, a silicone-acrylic resin, a silicone-urethane resin, and a polyolefin resin, and
- wherein the weight ratio of the (b) water-based resin particles to the (a) alkali metal salt of the organic acid, represented as the weight of the (b) water-based resin particles/the weight of the (a) alkali metal salt of the organic acid, is not less than 0.02.
