る欠点がある。These conventional dry lubricants have drawbacks such as an inability to increase the drawing speed, a reduction in total area reduction, and difficulty in rationalizing the pre-processing and post-processing steps for drawing. Furthermore, sulfur conventionally used as an extreme pressure additive is also harmful to the human body where odor is severe. Molybdenum disulfide, tungsten disulfide, glue graphite, etc. are expensive and difficult to handle because they are black fine powder, and at the same time, the finished surface of the wire is black, so degreasing after drawing is extremely difficult. There are disadvantages.
従つて本発明はこれら従来の乾式潤滑剤の欠点を改良
することにある。It is therefore an object of the present invention to remedy the disadvantages of these conventional dry lubricants.

高めたことにある。The present invention relates to a dry lubricant comprising the above-mentioned conventional dry lubricant mainly composed of metallic soap or alkali soap and further added with an adduct (powder) of melamine and isocyanuric acid or cyanuric acid. This is because the drawability has been dramatically improved.

けんを粉砕後に他の添加剤と一緒に添加し粉体混合機を
用いて均一混合しても良い。As a method of adding an adduct of melamine and isocyanuric acid or cyanuric acid (hereinafter referred to as MCA) to a dry lubricant, it is added during metal soap production or alkali soap production and then pulverized, or metal soap or alkali soap is added. May be added together with other additives after pulverization, and may be uniformly mixed using a powder mixer.

1〜30重量%、好ましくは2〜10重量%が最適である。The amount of MCA added depends on the type of metal soap or the type of alkali soap and the type and amount of other additives.
1-30% by weight, preferably 2-10% by weight is optimal.
添加量が0.1重量%以下の場合は従来の乾式潤滑剤と

つて経済上不利となるだけである。When the amount is less than 0.1% by weight, no significant difference in lubricating performance from the conventional dry lubricant appears, and when the amount is more than 30% by weight, the lubricating effect is not further improved, resulting in high cost and economical cost. It is only a disadvantage.

かりでなく、しかも伸線肌が黒くなることなく、仕上る
為に脱脂が非常に容易となる。又腐蝕性ガスを発生させ
ない為、脱脂を行わないで焼鈍することも可能である。Conventionally, in the case of dry drawing of a stainless wire, a chlorine-based or fluorine-based resin coating or a oxalate coating is applied to the surface of the wire before drawing, and then a black extreme pressure additive (eg, MoS 2 , WS 2 , wire drawing using a dry lubricant containing graphite. For this reason, the drawn skin becomes very black skin, so that the original white skin of stainless steel is obtained, and the generation of corrosive gas or clogging of the annealing pipe in the bright annealing furnace in the later process is to be prevented. Therefore, a sufficient degreasing step is required. However, the use of the dry lubricant of the present invention not only eliminates the necessity of these pretreatment agents prior to wire drawing, but also makes the wire drawing black without blackening, making degreasing very easy to finish. Becomes Since no corrosive gas is generated, annealing can be performed without performing degreasing.

Etc.) (for example, processing from 5.5 mm to 4.5 mm wire diameter)
In the conventional dry lubricant, it was possible to draw only at a maximum speed of 60 m / min, but by using the dry lubricant of the present invention, it was possible to double the speed to 120 m / min. Become. Also, for example, a PC steel wire with a wire diameter of 10 mm coated with phosphate is used.
When drawing at 200m / min, up to 4.0mm, the average dry dry lubricant from 70 to 80 tons per die was
By using the lubricant of the present invention, the production can be increased to an average of 150 to 200 tons per die.
また光輝焼鈍されたステンレス線(SUS−304)に於て
従来の乾式潤滑剤では総減面率が最高80%であつたもの
が本発明の乾式潤滑剤では86%迄伸線可能となる。The bright annealed stainless wire (SUS-304) can be drawn up to 86% with the dry lubricant of the present invention, while the conventional dry lubricant has a total area reduction rate of at most 80%.

-304) for wire drawing up to 0.6mm in diameter, conventionally coated with chlorine-based or fluorine-based resin, then drawn using a normal dry lubricant, degreased with chlorinated organic solvent, and bright annealed doing. In this step, if the dry lubricant of the present invention is used,
Wire drawing can be performed sufficiently without applying a pretreatment agent coating as in the conventional process, and if a pretreatment agent is not required, solvent degreasing after wire drawing is naturally unnecessary.
これらによつて作業の合理化はもちろん、ランニング
コストの低下、ならびに伸線材の品質向上が計れること

It can be applied to dry drawn wire such as iron wire, zinc plated steel wire, zinc or copper plated iron wire, Ni plated stainless steel wire, or copper alloy wire, aluminum alloy wire, nichrome wire etc. .

も出来るが、更にきれいにする場合も簡単なアルカリ脱
脂で容易に脱脂することが出来た。In addition, since the lubricants of the conventional comparative examples C and F contain molybdenum disulfide, the drawn wire becomes greenish black, and thus, at the present time, degreasing is repeated several times by steam cleaning with trichlene. However, the surface of the wire rod drawn only with the lubricant of the present invention (Example 5) does not use a chlorine-based resin as a pretreatment agent, so that this resin does not remain, and the MCA is white. Therefore, it is not necessary to degrease trichlene after drawing to finish the drawn skin white, and it can be passed to the next annealing step as it is, but even more clean can be easily degreased by simple alkali degreasing. done.
試験例 2 JIS規格SUS−304のバネ用ステンレス鋼線の線引加工
は従来次の様な伸線条件下で行われている。Test Example 2 Drawing of stainless steel wire for spring of JIS standard SUS-304 is conventionally performed under the following drawing conditions.

同程度であつた。Test material: JIS standard SUS-304 material Bright solid solution heat treated, Ni-plated Pretreatment agent: Fluoro resin coating treatment Test material wire diameter: 2.0 mm Finished wire diameter: 0.6 mm Number of dies: 9 Linear speed: 250 m / min Under the drawing conditions, the wire was conventionally drawn using the dry lubricant of Comparative Example D, or the dry lubricant of Example 4 of the present invention was used without applying the fluorine resin coating. When used and subjected to wire drawing under the same drawing conditions, the wire drawing could be performed without any change from the conventional process, and at the same time, the spring workability in the subsequent process was almost the same.
これによつて高価なフツソ系前処理剤が不要となり、
フツソ系又は塩素系溶剤での処理も必要がなくなり公害
問題も解消された。This eliminates the need for expensive fluorous pretreatment agents,
This eliminates the need for treatment with a fluorine-based or chlorine-based solvent, thus eliminating the problem of pollution.

が短い等の問題が発生している。Test Example 3 Wire drawing of special steel (high carbon bearing steel, JIS standard SUJ material) has conventionally been performed by applying a phosphoric acid coating or a lime soap coating before drawing after descaling by pickling. In recent years, except for this pretreatment step, shot blasting is performed as it is, but the load on the lubricant is large, so the desired processing rate can not be obtained, the linear speed is very poor, and the die life is short And other problems have occurred.
この用途に次の伸線条件で本発明の潤滑剤を使用し

However, when the lubricant of Example 7 of the present invention was used, the linear velocity could be increased to a maximum of 120 m / min.
Also, because it does not contain molybdenum disulfide, it has a beautiful finished skin. At the same time, it was confirmed that the rust-prevention performance of the drawn wire, which is greatly affected by the sulfur content, was also greatly enhanced.

In the prior art, the lubricant of Comparative Example F was used, and the drawn amount until the tolerance of the finished super steel dies increased by 3/100 was 70 to 80 tons on average, but the lubricant of Example 3 of the present invention was used. The average die life was increased to 150 to 200 tons (i.e., the finished die life was doubled on average).
又比較例Fには多量の二硫化モリブデンを含有してい
た為仕上り肌は非常に黒くダイスマークの発見が困難で
あつたものが、今回非常にきれいな伸線肌となつた為に
容易にダイスマークが発見されることになつた。In Comparative Example F, a large amount of molybdenum disulfide was contained, so that the finished skin was very black and it was difficult to find a dice mark. The mark has been found.
