Definitions
- the present invention relates to an aqueous lubricant for plastic working of a metal material for imparting excellent lubricity to a surface of a metal material such as steel, stainless steel, titanium, and aluminum without being subjected to a chemical treatment, and a method of using the same. More specifically, the present invention provides excellent lubricity without chemical conversion on the surface of metallic materials such as steel, stainless steel, titanium, and aluminum used in plastic working such as forging, drawing, and drawing.
- the present invention relates to an aqueous lubricant for plastic working of a metal material for easily forming a film having a lubricating agent, and a method for treating a lubricating film on a metal material by using the lubricant to form a lubricating film on a metal surface.
- a lubricating film is formed on the metal surface in order to prevent seizure or galling caused by metal contact between the workpiece and the tool.
- the lubricating film formed on the metal surface there are two types: a type that physically attaches a lubricant to the metal surface, and a type that uses a lubricant after forming a chemical conversion film on the metal surface by a chemical reaction. is there.
- Lubricants that are physically attached to the metal surface are generally used for light working because they have poor adhesion compared to those used by forming a chemical conversion coating on the metal surface.
- a phosphate coating or oxalate coating is formed on the metal surface as a chemical conversion coating that acts as a carrier, and then a lubricating lubricant is used.
- This type has a two-layer structure consisting of a chemical conversion coating as a carrier coating and a lubricant, and exhibits extremely high seizure resistance. Therefore, it has been used in a very wide range in the plastic working fields such as wire drawing, pipe drawing, and forging. Particularly in plastic processing, where processing is severe, a method of using a phosphate film or an oxalate film as a base and using a lubricant on the base is often used.
- Lubricants used on chemical conversion coatings can also be broadly divided into two categories depending on the method of use. One is a type in which a lubricant is physically attached to a chemical conversion coating, and the other is a type in which a lubricant reacts and attaches to a chemical conversion coating.
- a lubricant mineral oil, vegetable oil, and synthetic oil are used as base oils and an extreme pressure agent is added thereto, or a solid lubricant such as graphite or molybdenum disulfide is added to water with a binder component. Dissolved, adhered and dried and used.
- These lubricants have the advantage that they can be easily processed by spray coating and dip coating, so there is little need for liquid management.
- 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 blended (Japanese Patent Application Laid-Open No. 52-200) No. 967) j is shown, but nothing comparable to chemical conversion film treatment has been obtained.
- Means for solving these problems include, for example, the invention of Japanese Patent Application Laid-Open No. 10-85085 filed by the same applicant. It consists of (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 oil, (D) a surfactant and (E) water.
- the present invention relates to an aqueous lubricant for cold plastic working of metal in which a solid lubricant and an oil are uniformly dispersed and emulsified, respectively.
- the lubricant according to the present invention is industrially industrial because the oil component is emulsified.
- the invention of 2000-6 3880 comprises (A) a synthetic resin, (B) a water-soluble inorganic salt and water, and the solid content weight ratio (B) / (A) is 0.25 / 1 to 9/1, and the synthetic resin
- the present invention relates to a lubricant composition for plastic working of a metal material, in which is dissolved or dispersed.
- the lubricant according to the present invention contains a synthetic resin as a main component, and has not yet achieved sufficient lubricity stably under severe processing conditions.
- the present invention is to solve the problems of the above-mentioned prior art, and in consideration of global environmental protection, can be used for various metal materials, and can be easily processed.
- the present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, a water-soluble inorganic salt, a lubricant selected from molybdenum disulfide and graphite, and an aqueous solution containing wax are blended at a specific ratio.
- the present inventors have found that excellent lubrication performance can be exhibited by performing the method, and have completed the present invention. Further, the present inventors have found a processing method for forming an excellent lubricating film having a specific adhesion amount on the surface of a metal material by energy saving and space saving, and have completed the present invention.
- the aqueous lubricant for plastic working of a metal material of the present invention comprises (A) a water-soluble inorganic salt, (B) one or more lubricants selected from molybdenum disulfide and graphite, and (C) a wax. And these components are dissolved or dispersed in water, and the solid content ratio (weight ratio) (8) / (8) is 1.0 to 5.0, and (C) (A) is 0.0. It is characterized by being within the range of 1 to 1.0.
- the water-soluble inorganic salt is at least one selected from the group consisting of sulfates, silicates, borates, molybdates, and tungstates.
- the wax is a natural wax or a synthetic wax having a melting point of 70 to 150 ° C. dispersed in water.
- the cleaned metal material is brought into contact with the lubricant and then dried, so that the weight of the metal material adhered to the surface of the metal material is 0.5 to 4 Og.
- / m 2 is a method for treating a lubricating film of a metallic material, characterized by forming a lubricating film of / m 2 .
- the cleaning of the metal material is at least one selected from the group consisting of shot blast, sand blast, alkali degreasing, and acid cleaning, and the metal material is heated to 60 to 100 ° C. It is preferred that the lubricant be brought into contact with the lubricant after warming.
- Figure 1 is an illustration of the posterior drill test
- Fig. 2 is an illustration of the spike test.
- the (A) water-soluble inorganic salt used in the aqueous lubricant for plastic working of metallic materials of the present invention is for imparting hardness and strength to the lubricating film. Therefore, the selected water-soluble inorganic salt must have the property of dissolving uniformly in the solution and forming a strong film when dried. As the water-soluble inorganic salt having such properties, it is preferable to use at least one selected from the group consisting of sulfates, silicates, borates, molybdates, and tungstates.
- Examples include sodium sulfate, potassium sulfate, potassium gayate, sodium borate (sodium tetraborate), potassium borate (potassium tetraborate, etc.), ammonium borate (ammonium tetraborate, etc.), ammonium molybdate, molybdenum Acid sodium, sodium tungstate and the like. These may be used alone or in combination of two or more.
- the one or more lubricants selected from molybdenum disulfide (B) and graphite used in the present invention are for imparting lubricity.
- Lubricants used in the present invention Is present in a form dispersed in the aqueous lubricant for plastic working of a metal material of the present invention, and a known surfactant can be used if necessary.

More preferably, it is in the range of 2.0 to 4.0. If this ratio is less than 1.0, the lubricating performance is low, which is not preferable. If this ratio exceeds 5.0, the liquid stability of the lubricant is undesirably reduced.
- the wax (G) it is preferable to use a natural wax or a synthetic wax although the structure and the type thereof are not specified. Pex components are added to improve the lubricity of the film by melting by the heat generated during plastic working.
- the melting point is 70 to 150 ° C and that it is stable in an aqueous solution and does not decrease the film strength so that the effect is exhibited in the initial stage of the application.
