Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. 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. 2. The lubricant composition as set forth in claim 1 , further comprising: at least one selected from (e) an inorganic acid salt and (f) inorganic powder. 3. The lubricant composition as set forth in claim 1 , wherein the (b) water-based resin particles include particles having a particle diameter of not less than 1.0 μm in an amount of not more than 5% by weight relative to a total amount of the (b) water-based resin particles. 4. 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, and the (b) water-based resin particles include particles having a particle diameter of not less than 1.0 μm in an amount of not more than 5% by weight relative to a total amount of the (b) water-based resin particles, 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. 5. The lubricant composition as set forth in claim 4 , wherein the (b) water-based resin particles have an average particle diameter of 0.01 μm to 10 μm. 6. The lubricant composition as set forth in claim 4 , further comprising: at least one selected from (e) an inorganic acid salt and (f) inorganic powder.
