Description

TECHNICAL FIELD [0001] The present invention relates to a lubricant composition for use in a forging process, and a method for producing the same.

The present invention relates to a lubricant composition for use in a forging process and a method of making the same, and more particularly to a hot forging denture lubricant composition used in a hammer press process. More particularly, the present invention relates to a releasing lubricant composition that is harmless to the human body and is environmentally friendly, in addition to its applicability, releasability, spectroscopic properties and odorless properties in hammer or press molding.

Generally, the lubricant used in the forging process is a metal material used as a release lubricant composition used for processing metal materials and non-ferrous metal materials, a viscosity required in the process, a processing precision of the material, a size of the surface pressure, Type forging lubricant is used.

The forging process is a metal machining method in which a metallic material such as a metal block or a thick metal plate is placed between dies to press and press the dies so as to deform and form the dies. Typically, the dies are hammer and press forged . Such forging is distinguished by hot forging to be processed at a high temperature, hot tempering which is performed at a relatively lower temperature than the hot forging, and cold forging which is performed at room temperature.

Generally, in the hot forging, the preheating temperature of the mold is 180 ° C. to 230 ° C. during hot forging, but the temperature of the forging material reaches 1,200 ° C. and the temperature at which the material is conducted to the mold reaches hundreds of degrees.

In the case of hot forging, mechanical cracks may occur when the cracks due to thermal fatigue of the metal and the state of the mold exceed the yield point due to a rapid temperature rise while the mold is continuously repeated as the mold is continuously heated at high temperature, The temperature of the mold may not be maintained at an appropriate temperature or there may be a problem of the material being stuck due to uneven pressure and stress. Therefore, various lubricants suitable for hot forging are required to solve the above problems.

Lubricants suitable for hot forging are, first, excellent cooling effect. In order for the normal operation to continue, the temperature of the mold is preferably maintained at about 250 to 290 DEG C, and when the temperature of the mold exceeds the above temperature, the mold shape starts to be destroyed by the cracks mentioned above. Second, applicability should be smooth. In particular, even if the temperature of the mold is normal, a temperature difference of usually 20 to 30% occurs before and after forging. However, the coating force should be maintained even at such a temperature difference, Third, partial hardening should not occur. This is because the defect rate is increased during the continuous forging process.

The releasing lubricant composition used for hot forging can be broadly classified into a hydrocarbon-based oil component and a non-hydrocarbon-based lubricating composition.

Conventionally, a release by a forced explosive force was performed at a high temperature by using a hydrocarbon-based oil component. However, when the hydrocarbon-based oil component is used, there are problems such as fuming, ignition, soot, odor and the like, and there is a problem that a crack is generated in the mold and the material due to an unreasonable explosive force.

Therefore, the use of hydrocarbon-based lubricant compositions has been reduced due to the problems of the hydrocarbon-based lubricant compositions, and they have been replaced by non-hydrocarbon lubricant compositions. As the non-hydrocarbon lubricating composition, there is a water dispersion lubricating composition.

In the case of a water dispersion type lubricating composition, problems such as hydrocarbon-based lubricating compositions are few and stability is high, but CMC (carboxy methyl cellulose) and gum arabic are used as thickening agents, And there is a problem in that gelation is progressed and the water is not dispersed after a certain period of time. In particular, since the hot forging process is performed at a high temperature, the thickener contained in the lubricant composition of the water dispersion system burns, odor is generated, and CMC is toxic, and toxicity due to vaporization causes the workability of the hot forging process, There are problems with bad influence.

In the prior art, CMC is used as a thickener in the case of Patent Document 1, and there is a problem mentioned above. In the case of Patent Document 2, thickening property is secured by using potassium silicate or lyrium silicate or the like, There is a drawback that it is disadvantageous to the continuous process because the partial hardening, that is, the milling phenomenon, may occur in the process.

Accordingly, there is a need for a hot forging lubricant composition which has properties of a lubricating composition required in a hot forging process but does not adversely affect the workability of the process and the working environment as a more environmentally friendly composition.

[Production of releasing lubricant composition for use in forging process]

(Preparation Example 1: preparation of peach tree essence and apricot kernel juice)

The juvenile juvenile juice and apricot juice are obtained by dissolving peach tree or apricot juniper obtained in the peach tree shown in Fig. 1 in purified water.

That is, 100 kg of each of peach tree and apricot husk were completely dissolved in 30 kg of purified water at about 80 캜, and the impurities were filtered by pressure filtration using a filter cloth having a filtration hole of 20 탆. 5 L of 10 N hydrochloric acid was added to the peach husk liquor which had been subjected to the above pressure filtration to precipitate impurities and filtered. Then, 10 N sodium hydroxide was mixed until the pH reached 7 to purify the peach tree juice.

(Example 1)

20 kg of phthalic acid was mixed with 100 kg of purified water and stirred for 30 minutes or more. Sodium hydroxide was then mixed until neutralized to pH 7 and stirred for at least 1 hour. Then, 7.5 kg of the purified peach tree essence was mixed with purified water mixed with the phthalic acid and stirred for 40 minutes or more to prepare Example 1.

(Example 2)

Example 2 was prepared by mixing 15 kg of peach tree essence in the same manner as in Example 1 above.

(Example 3)

Example 3 was prepared by mixing 45 kg of peach tree essence in the same manner as in Example 1 above.

(Example 4)

The same procedure as in Example 1 was carried out except that in Example 1, an apricot kernel juice was used instead of peach juice.

(Example 5)

The same procedure as in Example 2 was carried out except that apricot kernel juice was used in place of peach juice in Example 2.

(Example 7)

The procedure of Example 1 was repeated, except that adipic acid was used instead of phthalic acid in Example 1.

(Example 8)

The procedure of Example 4 was repeated, except that adipic acid was used instead of phthalic acid in Example 4.

(Comparative Example 1)

Comparative Example 1 was prepared in the same manner as in Example 1, except that 7.5 kg of CMC was mixed instead of peach seed extract in Example 1.

[Property Test]

Example 1 Example 2 Example 3 Comparative Example 1 Viscosity (cP) 820 950 2043 790 flash point none none none none Coating property (Coating film thickness) 0.5mm 0.6mm 0.9mm 0.4mm smell none none none Odor Gas (carbon monoxide) 0.001 ppm 0.001 ppm 0.002 ppm 0.003 ppm Lubricity 0.01mm 0.01mm 0.01mm 0.1mm

Viscosity measurements were made using a rotary viscometer (Brookfield DV-E Viscometer) at 40 ° C.

The applicability was evaluated by spraying 10 ml of the lubricant composition on the material, and measuring the thickness of the coating film.

The smell was determined by the smell generated during the hot forging process after application.

The presence of gas was determined by measuring the toxic gas generated during the hot forging process at about 250 ° C after application and measuring it by installing a portable gas meter (Drager X-am 2000).

The lubrication was measured by measuring the wear of the ball in the ball mill after the ball mill ball was lubricated for 1 hour.

As shown in Table 1, in Examples 1 to 3, odor was not generated unlike Comparative Example 1 in which CMC was used as a thickener, and it was confirmed that the generation of monoxide gas was reduced even at a high temperature of 200 ° C or more in the hot forging process.

[Dissimilarity test]

The durability of Examples 1 to 3 and Comparative Example 1 was measured and shown in Table 2 below.

Example 1 Example 2 Example 3 Comparative Example 1 Dysplasia good good good Generally good Break-up phenomenon 0/50 0/50 0/50 2/50 Film destruction 0/50 0/50 1/50 39/50

In the above releasing property test, Examples 1 to 3 and Comparative Example 1 were respectively applied to the material by spraying and hot forging. These were repeated 50 times each to confirm the mold release between the mold and the material.

The fracture phenomenon was confirmed while the lubricant remained in the mold and interrupted the continuous hot forging in Examples 1 to 3 and Comparative Example 1 by hot forging.

The film breakage was treated such that the coating film of the lubricant composition treated in the hot forging process was damaged, so that the coatings of Examples 1 to 3 and Comparative Example 1 were formed to a thickness of 0.3 mm on a steel plate material of 1 kg, and the iron plate with the coating was freely dropped at a height of 1 m And it was confirmed whether or not the coating was broken.

As shown in Table 2, it can be seen that Examples 1 to 3 have a similar or better mold releasing effect to Comparative Example 1, and in particular, the phenomenon of breakage and film breakage is remarkably reduced. In the continuous process of hot forging And the film is held on the material before and after the forging, so that it can have a more advantageous effect for preventing corrosion of the material.
