Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lubricant for processing a metal material, which can impart excellent lubricity to a surface of a metal material such as steel, stainless steel, titanium, aluminum or the like without subjecting the surface to chemical conversion treatment. The present invention relates to a water-based lubricant for plastic working of materials and a technique related thereto. More specifically, the present invention provides a lubricating film suitable for performing a plastic working such as forging, drawing, and drawing a metal material such as steel, stainless steel, titanium, and aluminum, and performing a chemical conversion treatment. Aqueous lubricant for plastic working of metal materials that can be formed without
And related technology.

[0002]

Generally, when a metal material such as steel or stainless steel is subjected to plastic working, the surface of the metal material is prevented from seizing or galling caused by metal contact between the workpiece and the tool. A lubricating film is provided.

[0003] As such a film, there are a type in which a lubricant is physically attached to the surface of a metal material and a type in which a chemical conversion treatment film is formed on the surface of the metal material by a chemical reaction and then the lubricant is used. There are things.

[0004] Lubricants that are physically attached to the surface of a metal material are generally used for light machining because they have poorer adhesion than those used by forming a chemical conversion coating on the surface of the metal material.

[0005] In the type using a chemical conversion coating, a phosphate film or an oxalate film serving as a carrier is formed on the surface of a metal material, and then a lubricating lubricant is used. This type has a very high seizure resistance because it has a two-layer structure of a chemical conversion film as a carrier film and a lubricant. For this reason, it has been used in a very wide range in the field of plastic working such as drawing, drawing and forging. In the field of plastic working which is particularly severe in processing, a method of forming a base coat such as a phosphate coat or an oxalate coat on a metal surface and using a lubricant on the base coat is often used.

[0006] Lubricants used on chemical conversion coatings can be broadly divided into two types depending on the method of use.

[0007] One is a type in which a lubricant is physically attached to a chemical conversion treatment film, and the other is a type in which a lubricant is reacted and attached to a chemical conversion treatment film.

As the former lubricant, mineral oil, vegetable oil and synthetic oil are used as base oils, into which extreme pressure agents are added,
Alternatively, a solid lubricant such as graphite or molybdenum disulfide may be dissolved in water together with a binder component and used in the adhesion drying step. Since these lubricants can be easily used by spray coating or dip coating, they have the advantage that liquid management is almost unnecessary, but they have low lubricity, so they can be used when lubricity is relatively light. Many.

On the other hand, in the latter, a reactive soap such as sodium stearate is used as a lubricant. If a particularly high lubricity is required, a reactive chemical soap is used after forming a chemical conversion coating. are doing.

However, when a chemical conversion treatment or a reactive soap involving a chemical reaction is used, liquid management, temperature control for controlling the chemical reaction, and disposal / renewal due to deterioration of the liquid are required.

In recent years, for the purpose of global environmental protection,
Reduction of industrial waste is a major issue. Because of this,
A lubricant and a disposal method that do not generate waste are desired.

Furthermore, in the prior art, since the management of the process and the processing solution is complicated, simple processing is desired. As a means for solving such problems, a lubricant composition comprising a water-soluble polymer or an aqueous emulsion thereof as a base material and a solid lubricant and a chemical conversion film-forming agent mixed therein has been proposed (JP-A-52-2).
No. 0967), but none comparable to the chemical conversion film treatment has been obtained.

Also, (A) a water-soluble inorganic salt, (B) a solid lubricant, (C) at least one oil component selected from mineral oil, animal and vegetable oils and fats, and synthetic oils, (D) a surfactant, and (E) An aqueous lubricant for cold plastic working of metal in which a solid lubricant composed of water and an oil are uniformly dispersed and emulsified, respectively, has been proposed (JP-A-10-8085).
However, in the technology of this proposal, since the lubricant emulsifies the oil component, it is unstable for industrial use, and it is difficult to stably exhibit high lubricity.

Further, it contains (A) a synthetic resin, (B) a water-soluble inorganic salt, and water, and a solid content weight ratio (B) / (A)
Is from 0.25 / 1 to 9/1, and a lubricant composition for plastic working of a metal material in which a synthetic resin is dissolved or dispersed,
It has been proposed (JP-A-2000-63880).
However, the lubricant according to the technology of this proposal has a synthetic resin as a main component, and it is difficult to stably exhibit sufficient lubricity under severe processing conditions.

Accordingly, an object of the present invention is to solve the above-mentioned problems of the prior art.
In particular, in consideration of global environmental conservation, it can be used for various metal materials and can be easily treated, that is, it is related to a lubricant for metal material processing which does not require chemical conversion treatment, especially an aqueous lubricant for plastic processing of metal material. It is to provide technology. Above all, when performing metal forming such as steel, stainless steel, titanium, aluminum, etc.
It is an object of the present invention to provide a technology related to a lubricant for metal material processing, in particular, a water-based lubricant for plastic working of metal material, which enables easy processing in consideration of global environmental protection and does not require a chemical conversion treatment.

Means for Solving the Problems As the inventors of the present invention have intensively studied to solve the above-mentioned problems, a specific phosphate (A), a dispersant (B) and a lubricant (C) have been developed. It has been found that excellent lubricating performance is exhibited when is used, and the present invention has been completed.

That is, the above-mentioned problems are caused by Zn, Fe, M

The phosphate (A) used in the present invention imparts followability during processing and carrier properties of a lubricant. For this reason, it is important to have a property of uniformly dispersing or dissolving in a solution and forming a strong film when dried.

As a phosphate having such characteristics,
A phosphate (A) containing at least one kind of divalent or trivalent metal selected from the group consisting of Zn, Fe, Mn, Ni, Co, Ca, Mg and Al is exemplified. These may be used alone or in combination of two or more.

For example, there are the following phosphates.

That is, the dispersant (B) of the present invention not only enhances the dispersion stability of the phosphate particles, but also has a function of fixing the phosphate to the metal surface. In other words, the dispersant component is adsorbed on the surface of the phosphate particles, and the repulsive force and steric hindrance of the charge prevent the phosphate particles from colliding with each other in the surface treatment agent, thereby preventing coagulation and sedimentation. Further, the dispersant component is structurally
Since it has the ability to adsorb to the surface of the metal material, it becomes possible to fix the phosphate on the surface of the metal material, and an excellent film can be obtained only by coating and drying on the surface of the metal to be treated.

The preferred ratio (weight ratio of solid content) of the phosphate (A), dispersant (B) and lubricant (C) is (B) /
(A) = 0.01 to 5 (more preferably 0.1 to 5)
2), (C) / (A) = 0.1 to 5 (more preferably,
0.5 to 2.5). That is, the above-mentioned characteristics are further exhibited by setting such a combined ratio.

In the present invention, it is preferable that the composition further contains at least one inorganic salt (D) selected from the group consisting of sulfate, silicate, borate, molybdate and tungstate. . Thereby, the strength and adhesion of the film can be improved. The preferable ratio (solid content weight ratio) of the inorganic salt (D) is (D) / (A) = 0.01 to 10
(More preferably 0.1 to 4).

For the purpose of assisting the formation of a film, a known viscosity improver may be added to the treatment liquid, if necessary.

Further, the present invention is also solved by a surface-treated metal material characterized in that the lubricant for processing a metal material having the above characteristics is provided on the surface of the metal material having a thickness of 0.5 to 40 g / m ² .

Further, the present invention is also solved by a method for forming a lubricating film of a metal material, which comprises contacting the metal material with the lubricant for processing a metal material having the above characteristics and then drying the metal material.

Further, after the surface of the metal material is cleaned by at least one cleaning means selected from the group consisting of shot blasting, sand blasting, alkali degreasing, and acid cleaning, the metal material is treated with the metal material having the above characteristics. The problem is also solved by a method for forming a lubricating film of a metal material, which is brought into contact with a processing lubricant and then dried.
