Specification

Lubricant composition for processing water-based metallic materials

Technical field

The present invention relates to a lubricant composition for processing a water-based metal material, and a method for producing a warm pressed metal material using the same. More specifically, the present invention is excellent in workability, degreasing, working environment, etc., and is used in the field of plastic working of various metal materials, particularly non-ferrous metal materials such as magnesium-based and aluminum-based materials, particularly in the field of warm press working. The present invention relates to a suitably used lubricant composition for processing an aqueous metal material, and a method for efficiently producing a warm press-processed metal material using the lubricant composition.

Background art

[0002] In a conventional metal plastic casing, friction between a metal material and a tool or a mold is reduced, plastic deformation of the metal is performed more smoothly, and cooling and protection of the tool or the mold, and the tool are reduced. Lubricants are used for the purpose of facilitating release of metal materials from metal molds and molds. By the way, magnesium alloys are the lightest among practical metals and have excellent properties such as electromagnetic wave shielding properties, so their use is expanding in recent years. At present, the processing of magnesium alloys is mainly performed by die casting and thixomolding.With these processing technologies, it is necessary to grind the surface after processing and it is difficult to handle thin products. It is pointed out.

[0003] On the other hand, press working using a magnesium alloy plate as a work material enables the use of thin products, and there is no need for surface polishing after processing. However, magnesium alloys have poor additivity at room temperature, so the temperature during press working is usually 200-300 ° C. If the lubricating performance of the press oil is insufficient during this press working, the work material will break and will adhere to the mold. For this purpose, a dedicated lubricant is used.

As described above, the lubricant used for the plastic working of the magnesium alloy sheet is a lubricant that suppresses the breakage of the workpiece and the adhesion to the mold in a warm state, generally in a temperature range of 100 to 300 ° C. It is necessary to show high processing performance by having lubricating performance, and also to show performance that can be removed by a normal degreasing process. [0004] For warm working of magnesium alloy sheets, solid coating lubricants have been used so far. However, in this case, delaminating treatment is required after the working, and simple degreasing treatment cannot be performed. He helped to avoid inferior productivity.

On the other hand, with an oil-based lubricant, the mold becomes approximately 300 ° C at the time of pressing, so oil fumes are generated and

However, there is a problem in terms of workability, the workability is inferior, and there is a possibility that processing scratches may occur or cracks may occur. Therefore, there is a problem that it is difficult to use an oil-based lubricant.

As a plastic working lubricant for magnesium alloys, it has excellent degreasing properties and does not deteriorate the working environment. It is an alkali metal salt of a fatty acid having 10 to 18 carbon atoms and 7 to 20% by mass of an alkali metal salt of a fatty acid having 12 to 18 carbon atoms. A composition comprising an aqueous solution containing 2 to 6% by mass of an earth metal salt and an amount of an alkali metal hydroxide in a pH of 12 to 14 is disclosed (for example, see Patent Document 1). However, the plastic working lubricant for magnesium alloys does not contain a solid lubricant, and the plastic working property is not always sufficiently satisfactory.
