- An aqueous lubricant for plastic working is disclosed.
- This technique is an excellent technique having high processing performance as in Patent Document 1 by using a water-soluble inorganic salt as a main component of a solid film and blending a wax of a lubricant into the solid film.
- Patent 3984159 is an excellent technique having high processing performance as in Patent Document 1 by using a water-soluble in
- water-soluble inorganic salts and water-soluble resins are essential components of a solid film of an aqueous lubricant for plastic working.
- a lubricating film composed of a water-soluble inorganic salt or a water-soluble resin has sufficient film strength, and as described above, the lubricating film breaks due to being interposed at the interface between the die and the workpiece even under high surface pressure. This is because it is difficult to avoid direct contact between metals.
- a good lubricating state can be maintained during plastic working by combining an appropriate lubricant capable of reducing the friction coefficient with a solid film made of a water-soluble inorganic salt or a water-soluble resin.
- the film formation mechanism of the water-based lubricant for plastic processing composed of water-soluble components will be described.
- the water-soluble inorganic salt and water-soluble resin of the water-soluble component are dissolved or dispersed in water in the lubricant treatment liquid.
- the solvent water evaporates and lubricates.
- a film is formed.
- the water-soluble inorganic salt and the water-soluble resin are precipitated as solids on the surface of the metal material to form a solid film.
- the solid coating formed in this way has a coating strength that can withstand plastic processing, and exhibits good lubricity during plastic processing by incorporating an appropriate lubricant that reduces the friction coefficient.
- the water-soluble component is water-soluble, it has deliquescence and hygroscopicity, and the solid film formed on the surface of the metal material absorbs moisture in the atmosphere and absorbs moisture in a high-temperature and high-humidity environment. Due to moisture absorption, the solid film swells or dissolves with water and gradually changes from a solid to a fluid. When the solid film is fluidized, the film strength is remarkably reduced, and the lubricating film is cut off at the interface between the die and the workpiece under high surface pressure during plastic processing, and direct contact between metals occurs.
- plastic processing lubricants whose solid coating is composed of water-soluble components such as water-soluble inorganic salts and water-soluble resins absorb moisture under high temperature and high humidity environments, and the lubricity, workability and seizure resistance are greatly reduced. .
- the water-soluble component absorbs moisture that becomes a metal corrosive medium due to moisture absorption, and rust is generated on the surface of the metal material.
- rust occurs, not only the appearance is deteriorated but also the dimensional accuracy on the machined surface is lowered.
- plastic working it is important that when a metal material is pressed, it is molded according to the shape of the mold. The smoother the dimensional accuracy and the forged skin, the better the quality. Therefore, the rust generated before press working reduces the lubricity in order to increase the frictional force, and causes the dimensional accuracy to deteriorate and the forged skin to deteriorate due to the rust being pushed into the processed surface. Further, rust generated after press working increases the surface roughness on the processed surface, leading to a decrease in dimensional accuracy and a deterioration of the forged skin.
- the lubricating film composed of water-soluble components absorbs moisture under high temperature and high humidity environment, resulting in deterioration of lubricating performance and generation of rust. Therefore, it is difficult to store a metal material having a lubrication film formed for a long period of time while being exposed to the atmosphere. If a lubricated metal material is put in a sealed container and a moisture-proofing agent is added to suppress moisture absorption, it can be stored for a long period of time.
- the storage method is not industrially realistic.
- the phosphate treatment represented by the bonde treatment a chemical reaction is caused on the surface of the workpiece to precipitate crystalline phosphate.
- Phosphate is insoluble in water and does not absorb moisture even in high temperature and high humidity environments. Therefore, the lubrication performance is not lowered and the corrosion resistance is excellent, and the dimensional accuracy is not lowered and the forged skin is not deteriorated by rust. Therefore, it can be stored for a long time even in a high-temperature and high-humidity environment without worrying about the effects of moisture absorption or rust generation.
- the phosphate treatment has a problem in terms of environmental protection because industrial waste such as sludge is generated in large quantities when the film treatment is performed.
- an in-line system that consistently performs the process from forming the lubricating film to pressing as a measure to prevent moisture absorption has been put into practical use.
- This method is advantageous in that the press working is performed before moisture absorption, so that the influence of moisture absorption of the lubricating film can be ignored and the production efficiency can be improved.
- the lubricating film absorbs moisture when there is a production trouble, for example, when there is a long line stop due to production trouble or maintenance.
- the film temperature is higher than the outside air temperature
- moisture in the film evaporates and does not absorb moisture, but moisture absorption starts when the temperature drops to the outside temperature. In any case, moisture absorption of the lubricating film is inevitable in an environment where the film temperature is lowered to the temperature of the outside air.
- Water-soluble inorganic salts and synthetic resins are generally used for solid coatings of water-based lubricants for plastic processing, but among various synthetic resins, there are components that are less susceptible to moisture absorption than water-soluble inorganic salts. .
- synthetic resins described in Patent Document 1 acrylic resins, vinyl acetate resins, epoxy resins, urethane resins, and phenol resins are exemplified. Since these synthetic resins have few hydrophilic groups that cause moisture absorption in the structure and have low affinity with water, they have excellent water resistance, and performance degradation due to moisture absorption is small. However, these synthetic resins are dispersed as particles in the water-based lubricant.
- the water-based lubricant When the water-based lubricant is heated and used for the purpose of accelerating the drying of the lubricating film, the particles are aggregated and the dispersed state immediately deteriorates.
- the water-soluble inorganic salt is present in the form of ions in the water-based lubricant, so there is no problem in liquid stability even when heated at a temperature of less than 80 ° C. Therefore, the synthetic resin has poor dispersion stability in an aqueous lubricant as compared with a water-soluble inorganic salt.
- these synthetic resins are excellent in water resistance, but have poor film removal properties and cause various problems in the subsequent processes. For example, if the film removal is insufficient in the cutting process after press working, the coating component will contaminate the cutting coolant, and if it is a gear part, it will contaminate the lubricating oil after it is assembled to the transport equipment. Is concerned. Further, when plating is performed after the film removal step, not only does the film component enter and contaminates the plating solution, but also the portion where the film component remains causes poor plating.
- Patent Document 3 describes a lubricant composition for forming a lubricating film that is easily removed by washing with a synthetic resin having excellent film removal properties as a solid film.
- a lubricant composition for forming a lubricating film which is easily removed by washing with water wherein the content of (c) is 3 to 90 parts by weight with respect to 100 parts by weight of (a) + (b) in total.
- the solid film of this lubricant has a synthetic resin as a main component and does not contain a component for improving the film strength such as a water-soluble inorganic salt. Therefore, the film does not have sufficient film strength for plastic working, and film breakage occurs under high surface pressure, and seizure with the mold occurs. Therefore, such lubricants have insufficient performance under severe processing conditions.
- plastic processing water-based lubricants composed of water-soluble components do not reduce lubricity or seizure resistance due to moisture absorption even in high temperature and high humidity environments, and have excellent corrosion resistance and reduced dimensional accuracy due to rusting on the processed surface. None has so far been obtained that does not cause deterioration of the forged skin. On the other hand, no water-based lubricant can be used by heating, and no lubricant film can be easily removed.
- the water-based lubricant for plastic processing composed of Patent Documents 1 and 2 has a strong affinity for water and low water resistance, so that water vapor in the atmosphere is contained in the lubricating film under high temperature and high humidity environment. It penetrates into the metal material and reaches the surface of the metal material to generate rust. When rust occurs, not only the appearance is deteriorated but also the dimensional accuracy on the machined surface is lowered. In the plastic working, it is important that the metal material is formed according to the shape of the mold when pressed, and the smoother the dimensional accuracy and the forged skin, the better the quality.
- the rust generated before press working reduces the lubricity in order to increase the frictional force, and causes the dimensional accuracy to deteriorate and the forged skin to deteriorate due to the rust being pushed into the processed surface. Further, rust generated after press working increases the surface roughness on the processed surface, leading to a decrease in dimensional accuracy and a deterioration of the forged skin.
- the phosphate treatment represented by the Ponde treatment a chemical reaction is caused on the surface of the workpiece to precipitate crystalline phosphate. Since phosphate is insoluble in water and has high water resistance, it is excellent in corrosion resistance, and does not cause deterioration in dimensional accuracy or deterioration of forged skin due to rust. Therefore, it can be stored for a long time even in a high-temperature and high-humidity environment without worrying about the influence of rust generation.
- the phosphate treatment has a problem in environmental conservation because industrial waste such as sludge is generated in a large amount when the film treatment is performed.
- Water-soluble inorganic salts and synthetic resins are generally used for solid coatings of water-based lubricant coating agents for plastic working, but among various synthetic resins, there are components that have higher water resistance than water-soluble inorganic salts.
- Specific examples of the resin described in Patent Document 1 include acrylic resins, vinyl acetate resins, epoxy resins, urethane resins, and phenol resins. Since these synthetic resins have few hydrophilic groups in the structure and low affinity for water, they have high water resistance and excellent corrosion resistance. However, these plastics, when subjected to plastic working, have low followability with respect to the surface of the metal material when the material is deformed, so that the remaining film is reduced and sufficient corrosion resistance cannot be obtained.
- water-based lubricants for plastic processing composed mainly of water-soluble inorganic salts or synthetic resins have excellent corrosion resistance under high-temperature and high-humidity environments. So far nothing has happened.

{成分(A)}
・構成モノマー
樹脂成分(A){高分子材料(A)}は、少なくとも無水マレイン酸を含むエチレン性不飽和結合を有するモノマーの共重合体又は単独重合体からなる。このように、当該共重合体又は当該単独重合体は、構造中に無水マレイン酸部分を有し、アルカリ成分で中和すると水に溶解または分散させることができる。よって水を溶媒とする潤滑液中では樹脂成分(A)は溶解もしくは分散した状態にある。その潤滑液を金属材料表面に塗布して乾燥により水を蒸発させると樹脂成分(A)は金属材料表面に析出するが、その際にマレイン酸部分が材料表面と強固な結合を形成して良好な密着性が得られる。また、樹脂成分(A)の無水マレイン酸部分は無機補強成分(B1)の粒子表面に対して吸着作用があり、強固に結合するため樹脂成分(A)は無機補強成分(B1)の優れたバインダーとなる。したがって樹脂成分(A)は、無機補強成分(B1)との組合せにより、特に好適な潤滑皮膜の造膜剤として機能する。
樹脂成分(A)に係る共重合体は、無水マレイン酸部分が含窒素化合物で封鎖率10~80%(好適には30~60%)の比率で封鎖されていることを一特徴とする。ここで、封鎖率は、樹脂成分(A)に係る共重合体又は単独重合体の無水マレイン酸の全モル数を100とした場合に封鎖処理により封鎖した無水マレイン酸のモル数と定義される。封鎖手法としては、無水マレイン酸部分のイミド化、無水マレイン酸とカルシウム、マグネシウム等のアルカリ土類金属、亜鉛、アルミニウム、スズ、鉛等の両性金属、クロム、ニッケル、マンガン、鉄、銅等の遷移金属を反応させることによる金属化を挙げることができる。これらの中では無水マレイン酸部分をイミド化することが好適であり、イミド化により環化することがより好適である。樹脂成分(A)の無水マレイン酸部分を封鎖することで、その部分では疎水性を付与することができる。よって、無水マレイン酸部分をイミド化することで、その部分での水蒸気の吸着を抑制できるので潤滑皮膜の耐吸湿性が向上する。ここでの耐吸湿性とは潤滑皮膜が高湿度環境下でも潤滑性と耐焼き付き性が低下しないことを意味する。また、封鎖した無水マレイン酸部分は金属に対して吸着作用がある。よって、イミド化した無水マレイン酸は金属材料表面に対してインヒビターとして機能するため潤滑皮膜の耐食性が向上する。尚、イミド化率が高すぎるとアルカリ成分の中和で開環できる無水マレイン酸の比率が少なくなるので水に溶解または水分散ができなくなる。また、イミド化率が低すぎると耐吸湿性と耐食性の効果が十分に得られない。イミド化率が10%未満では耐吸湿性および耐食性は十分でなく、80%を超える場合は水溶化ができない。よってイミド化率は10~80%(好適には30~60%)である。ここで、イミド化する際の含窒素化合物としては、アンモニア、一般的な一級アミンであれば制限されないが、好適には、アンモニアである。ここで一級アミンとしては、例えば、メチルアミン、エチルアミン、n-プロピルアミン、i-プロピルアミン等の炭素数1~3のアルキル基を有する一級アミンが挙げられる。
樹脂成分(A)に係る共重合体又は単独重合体は、未封鎖の無水マレイン酸部分のアルカリ成分による中和度(アルカリ中和度)を40~100%にしたことを一特徴とする。ここで、中和度は、樹脂成分(A)に係る共重合体において未封鎖の無水マレイン酸の全モル数を100とした場合にアルカリ成分で中和された無水マレイン酸のモル数で定義される。なお、無水マレイン酸の中和はアルカリ成分が水酸化ナトリウムの場合で無水マレイン酸1モルに対して水酸化ナトリウムは2モル必要となる。このように、当該共重合体又は単独重合体の構造中に存在する無水マレイン酸部分をアルカリ成分で中和すると無水マレイン酸部分が開環する結果、当該共重合体又は当該単独重合体を水に溶解または分散させることができる。ここで、中和度が低いと吸湿の原因となるアルカリ成分の添加量が少なくて済むので潤滑皮膜の耐吸湿性は向上するが、中和度が40%未満では樹脂成分(A)を水溶化できずに潤滑剤中での分散状態が悪くなる。中和度は、より好ましくは40~80%である。
樹脂成分(A)に係る共重合体又は単独重合体は、重量平均分子量で5000から400000のものが好ましい。分子量が大きすぎると潤滑剤処理液の粘度が高すぎるため良好な塗布外観が得られなかったり潤滑剤の乾燥性も悪くなる。逆に分子量が小さすぎると塑性加工に対して皮膜強度が不足する恐れがある。
無機成分(B)としては、無機補強成分(B1)又は水溶性無機成分(B2)を使用することができる。ここで、無機成分として、無機補強成分(B1)を選択するか、水溶性無機成分(B2)を選択するかによって、塑性加工用水系潤滑剤の有する作用効果が異なる。尚、無機補強成分(B1)と水溶性無機成分(B2)とを組合せて使用してもよい。
・材質
無機補強成分(B1)は、水に不溶性または難溶性であって水溶性無機塩とは異なり水系潤滑剤中で完全に溶解せずに粒子の形で分散した状態である。ここで、本明細書にいう「不溶性または難溶性」とは、20℃において100gの水に対する溶解度が130mg以下であることを指す。ここでの無機補強成分(B1)は、水への溶解度が非常に低い粒子であって水との親和力が小さく吸湿しにくい。よって無機補強成分(B1)には、樹脂成分(A)の補強剤として固体皮膜の皮膜強度を向上させて尚且つ吸湿しない性質が求められる。また、無機補強成分(B1)のモース硬度が1~5であることが好ましい。モース硬度が1未満の場合は樹脂成分(A)の補強効果が十分でなく、5を超える場合は粒子が硬すぎるため成形用金型表面を激しく磨耗させる恐れがある。このような無機補強成分(B1)としては、具体例として、塩基性炭酸マグネシウム、炭酸カルシウム、塩基性炭酸亜鉛、水酸化マグネシウム、水酸化カルシウム、タルク、マイカ、リン酸カルシウム、リン酸亜鉛、トリポリリン酸二水素アルミニウムが挙げられる。これらは単独で用いてもよいし、二種類以上組み合わせてもよい。
無機補強成分(B1)の粒子径は0.1~10μmであることが好ましい。ここで、「粒子径」は平均粒径(メジアン径d50)であり、例えば(株)堀場製作所社製の粒度分布測定器(機種LA-920、粒子径基準:体積)で測定された値を指す。本発明の塑性加工用水系潤滑剤においては、無機補強成分(B1)は樹脂成分(A)との複合化によって形成される固体皮膜によって良好な潤滑性および耐吸湿性が得られる。これら二成分を複合化させるには無機粒子(B1)の粒子径を樹脂成分(A)の膜厚に近い大きさに合わせることが必要である。無機補強成分(B1)の粒子径が10μmを超える場合は樹脂成分(A)の膜厚に比べて大きすぎるために粒子が高分子膜から出た状態となり複合化が不十分となる。一方、粒子径が0.1μm未満であると複合化は十分であるが無機補強成分(B1)を粉砕微細化するのに多大な時間とコストを要するので経済的に不利である。よって無機補強成分(B1)の粒子径は、より好ましくは5μm以下、さらに好ましくは2μm以下である。
水溶性無機成分(B2)は、樹脂成分(A)との相互作用により、潤滑皮膜の皮膜強度を強化及び塑性変形時の金属材料表面に対する皮膜追従性を向上させる機能を有する。
ここで本明細書における「水溶性」とは、20℃において100gの水に対する溶解度が130mg以上であることを指す。さらに水溶性無機成分(B2)は、水系潤滑皮膜処理剤のpHを金属材料の腐食反応を起させない領域に調整又は金属材料表面に酸化皮膜を形成させる機能を有するため、耐水性が高い樹脂成分(A)との相乗効果により、優れた耐食性を示す。このような機能を有する水溶性無機成分(B2)としては、ホウ酸塩、ケイ酸塩、バナジン酸塩、モリブデン酸塩及びタングステン酸塩が挙げられる。これらは単独で用いてもよいし、二種以上組み合わせてもよい。特に好ましいのは、酸化皮膜を形成させるモリブデン酸塩及びタングステン酸塩である。
・材質
固体潤滑成分(C)は、それ自体が軟らかく滑り性があり、塑性加工時でのダイスと被加工材の間での摩擦力を低減させる機能を有する。塑性加工時に摩擦力が増大すると加工エネルギーの増大、発熱、焼付きが発生するが、固体潤滑成分(C)を本発明の塑性加工用水系潤滑剤に配合すると潤滑皮膜中で固体の形で存在して摩擦力の増大が抑制される。また、固体潤滑成分(C)は水に不溶性もしくは難溶性の粒子であって吸湿しない。そのような機能および性質を有する固体潤滑成分は、ワックス、ポリテトラフルオロエチレン、脂肪酸とその塩、脂肪酸アマイド、二硫化モリブデン、二硫化タングステン、グラファイト、メラミンシアヌレート、有機処理合成雲母、層状構造アミノ酸化合物が挙げられる。これらは単独で用いてもよいし、二種類以上組み合わせてもよい。
{防錆添加成分(D)}
本発明の水系潤滑剤は樹脂成分(A)の封鎖化(例えばイミド化)と無機成分(B)の複合化により優れた耐食性を示すが、さらに耐食性を向上させる目的で防錆添加成分(D)を配合することができる。ここで用いる防錆添加成分(D)は金属材料での錆の発生を抑制する腐食抑制剤であり、金属表面での酸化還元反応を抑制するインヒビターとして作用する成分である。尚、防錆性添加成分(D)は、水系潤滑皮膜処理剤の潤滑性を低下させない程度での配合が可能であり、配合量は全固形分に対して質量比で0.01~0.1であることが好ましい。
本発明の塑性加工用水系潤滑剤における液体媒体(溶媒、分散媒体)は水である。尚、乾燥工程での潤滑剤の乾燥時間短縮化のために水よりも低沸点のアルコールを配合してもよい。
次に、本発明に係る塑性加工用水系潤滑剤の組成について説明する。ここで、塑性加工用水系潤滑剤の塑性は、無機成分(B)が、無機補強成分(B1)である場合と、水溶性無機成分(B2)である場合とによって、好適な組成比が異なる。
[(A)+(B1)]/[(A)+(B1)+(C)]=0.2~0.97
(A)/(B1)=0.35~3.85
であることが好ましい。より好ましくは
[(A)+(B1)]/[(A)+(B1)+(C)]=0.5~0.90
(A)/(B1)=0.5~2.91
の範囲内である。前述のように、樹脂成分(A)は潤滑皮膜の造膜剤、無機補強成分(B1)は樹脂成分(A)の補強剤であり、これら二成分の複合化により強固な固体皮膜が形成される。ここで、 [(A)+(B1)]/[(A)+(B1)+(C)]が0.2未満では固体皮膜の相対量が少なく加工時に高面圧下で膜切れによる焼き付きが発生しやすく、0.97を超える場合は固体潤滑成分(C)が不足して摩擦力が増大する恐れがある。また、(A)/(B1)が0.35未満では樹脂成分(A)に対して無機補強成分(B1)が過剰となり無機補強成分(B1)を保持できないばかりか素材との密着性が得られず、3.85を超える場合は無機補強成分(B1)が不足して固体皮膜に十分な強度が得られない。
[(A)+(B2)]/[(A)+(B2)+(C)]=0.2~0.97
(A)/(B2)=0.2~8
であることが好ましい。より好ましくは
[(A)+(B2)]/[(A)+(B2)+(C)]=0.5~0.9
(A)/(B2)=0.5~6
の範囲内である。前述のように、樹脂成分(A)と水溶性無機成分(B2)は、樹脂成分(A)の相乗効果により、強固で、塑性変形時の金属材料表面に対する皮膜追従性が優れた固体皮膜が形成され、優れた耐食性を示す。ここで、[(A)+(B2)]/[(A)+(B2)+(C)]が0.2未満では固体皮膜の相対量が少ないため、加工時に高面圧下で膜切れによる焼き付きが発生しやすく、0.97を超える場合は固体潤滑成分(C)が不足して摩擦力が増大する恐れがある。また、(A)/(B2)が0.2未満では樹脂成分(A)に対して水溶性無機成分(B2)が過剰となり、潤滑皮膜の耐水性が低下するため、耐食性が得られず、8を超える場合は、水溶性無機成分(B2)が不足して固体皮膜に十分な強度や皮膜追従性が得られない。
本発明に係る塑性加工用水系潤滑剤は、液体媒体である水に樹脂成分(A)と無機成分(B)と固体潤滑成分(C)とを添加して混合することにより製造される。ここで、無機補強成分(B1)や固体潤滑成分(C)は水に不溶性もしくは難溶性の粒子であるため、それらの粒子を潤滑剤中で分散させる必要がある。分散方法は水に分散剤と成り得る界面活性剤を添加して十分に水に馴染ませた後に目的とする粒子を添加して分散状態が均一になるまで攪拌を継続する方法で行われる。攪拌方法はプロペラ攪拌、プロペラよりもせん断力の高いホモジナイザーでの攪拌が挙げられ、ボールミルやサンドミル等の湿式粉砕機でジルコニア、チタニア、ジルコニアビーズ等のメディアを用いて粒子を粉砕により一次粒子径を微細化して分散させることも可能である。なお、樹脂成分(A)は構造中の無水マレイン酸部分が粒子表面に吸着する作用があり優れた分散剤として機能するが、さらに安定した分散状態を得るために公知の界面活性剤を用いることもできる。なお、その界面活性剤の種類や構造は耐吸湿性と耐食性を損なわないものであれば特に制限は無い。また、分散液が発泡する場合は消泡剤として機能する界面活性剤を添加することも可能である。ここで、界面活性剤としては、非イオン性界面活性剤、陰イオン性界面活性剤、両性界面活性剤、陽イオン性界面活性剤、高分子界面活性剤のいずれも用いることができる。非イオン界面活性剤としては、特に限定されないが、例えばポリオキシエチレンアルキルエーテル、ポリオキシアルキレン(エチレンおよび/またはプロピレン)アルキルフェニルエーテル、ポリエチレングリコール(もしくはエチレンオキシド)と高級脂肪酸(例えば炭素数12~18)とから構成されるポリオキシエチレンアルキルエステル、ソルビタンとポリエチレングリコールと高級脂肪酸(例えば炭素数12~18)とから構成されるポリオキシエチレンソルビタンアルキルエステル等が挙げられる。陰イオン性界面活性剤としては、特に限定されないが、例えば脂肪酸塩、硫酸エステル塩、スルホン酸塩、リン酸エステル塩、ジチオリン酸エステル塩等が挙げられる。両性界面活性剤としては、特に限定されないが、例えばアミノ酸型およびベタイン型のカルボン酸塩、硫酸エステル塩、スルホン酸塩、リン酸エステル塩等が挙げられる。陽イオン性界面活性剤としては、特に限定されないが、例えば脂肪酸アミン塩、第四級アンモニウム塩等が挙げられる。高分子界面活性剤としては重量平均分子量が数百から十万程度であり、例えば構造中にアクリル酸、メタクリル酸、スルホン酸、マレイン酸、セルロース、キトサン、ポリエステル、ポリウレタン、ポリアミン、アルコール等を含有するものが挙げられる。これらの界面活性剤は各々単独でまたは2種以上組み合わせて使用することが出来る。
{適用対象}
本発明の塑性加工用水系潤滑剤は、鉄もしくは鋼、ステンレス、銅もしくは銅合金、アルミニウムもしくはアルミニウム合金、チタンもしくはチタン合金等の金属材料に適用される。金属材料の形状としては、棒材やブロック材等の素材だけでなく、鍛造後の形状物(ギヤやシャフト等)の加工も考えられ、特に限定されない。
次に、本発明の塑性加工用水系潤滑剤の適用方法を説明する。本適用方法は、金属材料の清浄化工程、塑性加工用水系潤滑剤の適用工程及び乾燥工程を含む。以下、各工程を説明することとする。
金属材料を上記塑性加工用水系潤滑剤に接触する前に、ショットブラスト、サンドブラスト、ピーリング、アルカリ脱脂および酸洗浄よりなる群から選ばれる少なくとも一種類の清浄化処理を行うことが好ましい。ここでの清浄化とは、焼鈍等により成長した酸化スケールや各種の汚れ(油など)を除去することを目的とするものである。
本発明の水系潤滑剤を金属材料に適用する工程は、特に限定されるものではないが、浸漬法、フローコート法、スプレー法などを用いることができる。塗布は表面が充分に本発明の水系潤滑剤に覆われればよく、塗布する時間にも特に制限は無い。ここで、この際に乾燥性を高めるために金属材料を60~80℃に加温して塑性加工用水系潤滑剤と接触させてもよい。また、40~70℃に加温した塑性加工用水系潤滑剤を接触させてもよい。これらにより、乾燥性が大幅に向上して乾燥が常温で可能になる場合もあり、熱エネルギーのロスを少なくすることもできる。
塗布後塑性加工用水系潤滑剤を乾燥する必要がある。乾燥は常温放置でもかまわないが、60~150℃で1~30分行ってもよい。
本発明の塑性加工用水系潤滑剤により形成された潤滑皮膜は水系のアルカリ洗浄剤に浸漬するかスプレー洗浄することによって脱膜可能である。アルカリ洗浄剤は水に水酸化ナトリウム、水酸化カリウム等の一般的なアルカリ成分を溶解させた液であり、これに潤滑皮膜を接触させると樹脂成分(A)中の親水基のマレイン酸部分が加水分解して洗浄液中に溶解するので容易に脱膜することができる。よってアルカリ洗浄で脱膜不良による後工程での汚染やメッキ不良を未然に防ぐことができる。
以下に示す各成分を表1に示す組み合わせ及び割合にて実施例1~23及び比較例1~7の水系潤滑剤を調製した。これら全ての水系潤滑剤中の全固形分と水の重量比は1.5:8.5とした。また、樹脂成分(A)でのイミド化は、特開昭59-55791に記載された方法に準じ、すべてアンモニアを用いて行った。なお、比較例8はリン酸塩/石鹸処理である。
