When the wire is processed, the lubricant for the dry wire of the powder is used. This dry-type lubricant is a user that prevents the base material from being in direct contact with the die and burns, and is easy to slide, and can maintain a stable processing state.

For example, Patent Document 1 discloses a non-borate-containing dry wire lubricant containing a metal salt of a saturated fatty acid, a non-boron-containing water-soluble inorganic condensation compound, and/or a condensation precursor thereof. The lubricant for dry-stretching composed of a metal salt, an inorganic substance, and an additive of such a saturated fatty acid is formed into a powdery or granular shape. The powdery or granular dry wire lubricant can be used under high temperature, high pressure, high speed and severe wire drawing processing conditions, and can also correspond to a diameter reduction from a small diameter to a large diameter. Or low speed to high speed wire speed, so it can be widely used.

The lubricant for the dry type wire for powder or granules is as shown in Fig. 4. When the wire is processed, a large amount is injected into the die box 3, and a part thereof is Pulling the die 4 together with the wire 2 forms a lubricating film 6 to the wire 2 to prevent direct contact of the wire 2 with the die 4. The dry-type lubricant 10 to be used in the die box 3 is pulled by the die 4 and consumed by about 20% of the wire 2, but the rest is processed by the heat, and the dry-type lubricant 10 is Some of them are decomposed into carbides, and the lubricating energy is lowered, or the powders of the wire 2 or the die 4 are mixed together, and the quality of the wire is ensured, so that it cannot be used. Therefore, the total amount of residuals has to be discarded.

In recent years, the social situation is the social migration of the global environment, such as the re-use of resources, so the problem of such large consumption and a large amount of waste is being taken seriously. Further, in the form of powder or granules, problems such as deterioration of the working environment due to dust during use, damage to the health of the operator, and environmental pollution are caused. Further, depending on the shape to be processed, it is necessary to separately use or adjust the particle shape of the lubricant for dry wire drawing, which is inefficient on the operator side and the producer side. In order to improve the workability and productivity, and to improve the working environment, we are looking for a lubricant for dry-type wire that is innovative in the global environment and non-powder shape.

Example 2.

(Example 1)

After stirring 75 parts by weight of industrial stearic acid in a reaction vessel equipped with a stirring device, the mixture was heated and melted, and then 25 parts by weight of slaked lime was added. The mixture is continuously heated and stirred until viscosity is generated. When the mixture became hard, the heating and stirring were stopped, and the mixture was taken out and cooled, and pulverized into a 500 mesh sieve to have a pass rate of about 60% to obtain a calcium-based lubricant of a metal salt of a saturated fatty acid. 70 parts by weight of the obtained metal salt of the saturated fatty acid and 20 parts by weight of the polyethylene as the thermoplastic resin were heated and kneaded at 180 ° C using a heating kneader (trade name: Laboplast mill). The obtained solid was formed into a sheet having a film thickness of 0.5 mm or less by a hot press, and then cut into a strip having a width of 8 mm using a sheet cutter to obtain a lubricating material for a belt-shaped dry type strand.

(Comparative Example 1)

After stirring 75 parts by weight of industrial stearic acid in a reaction vessel equipped with a stirring device, the mixture was heated and melted, and then 25 parts by weight of slaked lime was added. The mixture is continuously heated and stirred until viscosity is generated. If the mixture hardens, stop The mixture was heated and stirred, taken out and cooled, and pulverized into a 500 mesh sieve to have a pass rate of about 60% to obtain a calcium-based dry type wire lubricant.

(Comparative Example 2)

The polyethylene was heated and kneaded at 180 ° C using a heating kneader (trade name: Laboplast mill). The obtained solid was formed into a sheet having a film thickness of 0.5 mm or less by a heating press, and then cut into a strip shape to obtain a belt-shaped polyethylene.

(Performance evaluation of wire drawing processing)

The use of the lubricating material for the band-shaped dry wire drawing of Example 1 as the lubricant of the wire material, the lubricant for the calcium-based dry wire drawing of Comparative Example 1, and the tape-shaped polyethylene of Comparative Example 2, respectively, were carried out by using a stretcher machine. Performance evaluation during line processing.

The base material wire (carbon steel 72A material) is acid-washed to remove the scale scale on the surface of the wire to be processed by 12% by weight hydrochloric acid aqueous solution, and then washed several times. For acid treatment neutralization and rust prevention, the immersion is heated to 80. A 1% by weight aqueous solution of Pollux around °C. The wire to be processed is pulled up from the aqueous solution of Pollux, dried, and a Pollux film is formed on the wire to be processed, and pretreated. Then, 1 g of the lubricating material for the strip-shaped dry wire obtained in Example 1 was placed in a die box, and the diameter of the wire diameter was 40 m/min, and the diameter of the wire diameter was 2.8 mm. →2.5mm →2.25mm →2.00mm In the third stage, the amount of the wire is 2 kg, and the wire of the processed wire which has been subjected to the pretreatment is carried out. In the three-stage wire drawing process, the lubricating material was used in only one pulse, and the lubricating material was not used in the 2, 3 pulse system.

In the same manner, 300 g of the calcium-based dry wire drawing lubricant of Comparative Example 1 and 1 g of the band-shaped polyethylene of Comparative Example 2 were used instead of the lubricating material, and the wire of the processed wire was stretched.

The results of visually observing the surface of the wire processed by the wire using each of the lubricants are shown in Table 1.

It is apparent from Table 1 that even in the wire diameter of either one, the lubricating material for the band-shaped dry wire of Example 1 is adhered to the surface of the wire after the wire is stretched to form a uniform film-like material for the dry wire of the tape-like wire. However, the powdery calcium-based dry-type lubricant for the conventional product of Comparative Example 1 is a second pulse, and a part of the metallic luster is produced by the slit film of the dry-type lubricant for stretching. Further, in the polyethylene resin of the thermoplastic resin of Comparative Example 2, the lubricating film was not uniformly formed from the first pulse to the wire, and metal plaque was generated. The second pulse is aborted.

The wire for the processing of the wire is washed with a detergent for the wire and wire (Light Clean A-1, manufactured by Kyoeisha Chemical Co., Ltd.), and the weight before and after washing. The amount of adhesion of each lubricant was calculated by a difference, and the surface of the wire after washing was observed by a magnification of 400 times with a laser microscope. The results are shown in Table 2.

As is apparent from Table 2, when the lubricating material for a belt-shaped dry wire drawing of Example 1 is used, the amount of adhesion of the lubricating material for the tape-shaped dry wire tends to be large even in the wire diameter of either one. The area ratio (flatness) of the flat portion which is produced by direct contact between the die and the wire tends to be lower than that of the comparative example. That is, it is confirmed that the wire is in a good condition. However, in Comparative Example 1, it can be seen that the flatness ratio after the second pulse is larger than that of the first embodiment, and a part of the burn can be seen after the third pulse is stretched. That is, after the third pulse, it was confirmed that the state of the wire was poor. To Comparative Example 2, more burns were seen than in the first pulse. That is, it can be confirmed that the state of the wire is poor.

The lubricant for dry-type wire for the dry wire of the first embodiment is a conventional lubricant for stretching wire which interacts with a thermoplastic resin to improve the film property and the adhesion, and has a belt shape, so that it can be efficiently pulled in Die, forming a uniform Lubricate the film. By the effect, it is judged that the use amount of the lubricant for the dry type wire which is less than the conventional one can be expected to be excellent in the drawing process, and is also in the form of a belt, which is less prone to be produced than the lubricant for the dry type of the conventional powder. Deterioration of the working environment caused by dust.
