Problems solved by technology

As the former, Patent Publication No. 58-30358 discloses "the cold or hot processing of metal pipes with bicarbonate (solid) as the main component, and a small amount of dispersant, surfactant and solid lubricant have been added therein." Lubricant for use”, but it still cannot reach the point where it can be widely used to replace chemical coating treatment
In addition, as the latter, Japanese Unexamined Patent Publication No. 52-20967 discloses "a lubricant composition made of a water-soluble polymer or its aqueous latex as a base material, and a solid lubricant and a chemical coating forming agent", but Lubricants that can rival chemical coating treatments are still not available

Embodiment 1～3

[0049] Examples 1-3, Comparative Examples 1-2

[0050] The lubricant composition was prepared in the ratio shown in Table 1. After dissolving the water-soluble inorganic salt in water, the phenol resin is dissolved and stirred well to prepare it. After dipping a Bowden friction test piece (material: SPC steel plate, 150 mm×75 mm×1.0 mm) in this lubricant composition for 30 seconds, it was dried at 100° C. for 30 minutes. Then, calcium stearate powder (manufactured by NOF Co., Ltd.) was evenly sprinkled on the entire dried film, and then it was used for the Bowden friction test.

[0051] In addition, before applying the lubricant composition for the Boden friction test, the test piece was subjected to the following pretreatment steps (1) to (2) and dried with hot air.

[0052] (1) Alkali degreasing (manufactured by Japan Parkerlizing Co., Ltd., fine lotion 4360, concentration 20 g / l, temperature 60° C., immersion for 10 minutes).

[0053] (2) Washing with water Spray washing...

[0055] Embodiment 4~17, comparative example 3~6

[0056] Modulate the lubricant composition according to the ratio shown in Table 2. After dissolving the water-soluble inorganic salt in water, the urethane resin, polyvinyl alcohol, phenol resin or acrylate resin is dissolved and fully stirred. Additive 1 (lubricant) shown in Table 2 (polyethylene wax dispersion, calcium stearate dispersion, polytetrafluoroethylene or palm oil emulsion) was added and stirred to prepare a lubricant composition. After immersing the Bowden friction test piece (material: SPC steel plate, 150mm×75mm×1.0mm) in this lubricant composition for 30 seconds, it was dried at 100° C. for 30 minutes, and used for the Bowden friction test. The Bowden friction test and the pretreatment of the Bowden test pieces were carried out in the same manner as in Examples 1-3.

[0057] After immersing the rear punched test piece in the lubricant composition for 30 seconds, place it in an oven at 100° C. for 30 minutes, ...

Embodiment 18～34

[0074] The lubricant composition was prepared in the ratio shown in Table 3. That is, after carrying out the same operation according to Examples 4-10, add additive B (molybdenum disulfide, graphite, boron nitride, graphite fluoride, vulcanized vegetable oil, MoDTC, MoDTP, ZnDTP or phosphite) with 2% by weight of the surface The active agent (non-ionic) is added after pre-mixing with water.

[0075] Coating treatment, Bowden friction test and rear punching test were performed in the same manner as in Examples 4-10.

[0076] The above test results are shown in Tables 1 to 3. As can be seen from Tables 1 to 3, Examples 1 to 34 using the lubricant composition for plastic working of metal materials according to the present invention exhibited excellent lubricity with simple operations. On the other hand, Comparative Examples 1 to 6, which were outside the scope of the present invention and could not satisfy the constitutional conditions of the present invention, failed to satisf...

Abstract

A lubricant composition for the plastic working of metals that does not require a phosphate undercoating, is waterborne, requires only a simple application process of immersion or spraying followed by drying, and provides an excellent lubricating performance comprises synthetic resin, water-soluble inorganic salt, and water. The weight ratio of the content of salt to that of synthetic resin is from 0.25:1 to 9:1. This composition can also contain liquid and / or solid lubricating agent(s) and extreme pressure additive.

Description

technical field [0001] The present invention relates to a lubricant for plastic processing of metal materials such as steel, titanium, aluminum, etc., which has excellent lubricity. More specifically, the present invention relates to a lubricant for plastic working metal materials that forms a coating having excellent lubricity by spraying or dipping a workpiece in plastic working and drying it immediately after coating. Background technique [0002] Generally, in order to reduce the friction between the processed material and the tool due to metal contact and prevent thermal adhesion or metal wear when processing metal materials plastically, liquid or solid lubricants are used. The lubricants used can be roughly divided into two types due to the different methods of use. One is a lubricant that physically adheres to the metal surface, and the other is a lubricant that adheres a lubricating material after forming a carrier film on the metal surface through a chemical reacti...
