発明の背景
本発明は、合成金属加工流体としても公知である、油を含有しない金属加工流体に関する。 BACKGROUND OF THE INVENTION This invention relates to oil-free metalworking fluids, also known as synthetic metalworking fluids.

金属加工は、金属加工片を造形し、望ましい設定の幾何学的規格に適合させることとして定義されている。金属加工は、２つの基本的なカテゴリーの機械加工と成形加工とからなる。機械加工は、研磨、旋削、フライス削り、タッピング、ブローチ削りおよびホビングを含む。成形加工は、熱間圧延および冷間圧延、引き抜き、鍛造、型押しおよび打ち抜きを含む。   Metalworking is defined as shaping a metal workpiece and conforming to a desired set of geometric standards. Metalworking consists of two basic categories of machining and forming. Machining includes grinding, turning, milling, tapping, broaching and hobbing. Forming includes hot and cold rolling, drawing, forging, embossing and stamping.

金属加工流体は、本質的に機械加工および成形加工の双方で使用される。この金属加工流体は、工作物と工具との間の潤滑を提供しなければならず、また、機械加工中に発生される熱の除去によって冷却も提供しなければならない。   Metalworking fluids are essentially used in both machining and forming processes. This metalworking fluid must provide lubrication between the workpiece and the tool, and must also provide cooling by the removal of heat generated during machining.

潤滑は、２つの可動面間の摩擦を減少させることとして定義されている。機械加工における２つの主なタイプの潤滑は、流体力学的であり、界面圧力性または極圧性（ＥＰ）を有する。流体力学的な潤滑は、液体潤滑剤の皮膜によって可動表面を分離することを包含する。界面潤滑または極圧（ＥＰ）潤滑は、複数の表面が共に摩擦される場合に被る摩滅を最少化する。ポリマー潤滑剤は、双方のタイプの潤滑を提供することができる。   Lubrication is defined as reducing the friction between two moving surfaces. The two main types of lubrication in machining are hydrodynamic and have interfacial or extreme pressure (EP). Hydrodynamic lubrication involves the separation of moving surfaces by a liquid lubricant coating. Interfacial lubrication or extreme pressure (EP) lubrication minimizes the wear experienced when multiple surfaces are rubbed together. Polymer lubricants can provide both types of lubrication.

金属加工流体は、油を含有する区分および油を含有しない区分の２つの主な区分に分級される。油を含有する区分は、ストレート油、水溶性オイルおよび半合成油を有し、これらの全ては、鉱油を一次潤滑剤として利用する。油を含有しない区分は、合成油として公知であり、この合成油は、水性輸送系または希釈剤中で潤滑性を生じる添加剤の組成物を含む。水溶性オイルおよび半合成製品は、市場の８０％のシェアを占め、非水性の還元ストレート油の区分は、１０％のシェアを占め、一方、合成油は、市場の１０％のシェアを占める。   Metalworking fluids are classified into two main categories: oil containing and non-oil containing. The oil containing segments include straight oils, water soluble oils and semi-synthetic oils, all of which utilize mineral oil as the primary lubricant. The oil-free section is known as a synthetic oil, which contains a composition of additives that produce lubricity in an aqueous transport system or diluent. Water-soluble oils and semi-synthetic products occupy an 80% share of the market, and the non-aqueous reduced straight oil category occupies a 10% share, while synthetic oils occupy a 10% share of the market.

存在するタイプの金属加工流体は、利点および欠点を有する。油を含有する製品は、潤滑性が優れており、用途が広範囲であり、および排液を腐蝕からバリヤー保護するという利点を有する。油を含有する金属加工流体の欠点は、水の硬度がしばしば流体の安定性に影響を及ぼし、発泡が高い洗浄力の乳化剤への前記流体の介在のためにしばしば問題となり、前記流体が大きな汚染物負荷を連行し、前記流体がタンクの廃棄および洗浄除去のためによりいっそう費用を必要とし、および前記流体が大きな微生物問題を有することにある。   Existing types of metalworking fluids have advantages and disadvantages. Oil-containing products have the advantages of excellent lubricity, wide application, and barrier protection of drainage from corrosion. The disadvantages of oil-containing metalworking fluids are that the hardness of water often affects the stability of the fluid, and foaming is often a problem due to the inclusion of the fluid in a high detergency emulsifier, which can cause significant contamination of the fluid. It entails a material load, the fluid requires more expense for tank disposal and cleaning, and the fluid has significant microbial problems.

合成油の使用は、微生物的利点に対して環境に由来する種々のファクターのために奨励される。しかし、大部分の消費者は、油を含有する製品を使用することを継続している。それというのも、比較される低い費用で、油を含有する製品の潤滑性は、良好であり、合成に関連した、腐蝕に由来する保守は、増加するからである。油によって提供された保護的バリヤー皮膜を欠く合成排液は、機械加工システムのボルトに腐蝕を生じかつ"凍結させる"可能性があり、保守を困難にする。付加的に、高い潤滑性の性能を有する合成製品は、同じ潤滑性の性能を有する、油を含有する製品と比較した場合に高価である。半合成製品での費用に応じての合成製品の減少された物理的潤滑性は、ヘビーデューティーな操作での合成製品の使用を制限する。   The use of synthetic oils is encouraged because of various factors derived from the environment for microbial benefits. However, most consumers continue to use oil-containing products. This is because, at a relatively low cost, the lubricity of oil-containing products is good and the corrosion-related maintenance associated with synthesis is increased. Synthetic drainage that lacks the protective barrier coating provided by the oil can corrode and "freeze" the bolts of the machining system, making maintenance difficult. Additionally, synthetic products with high lubricity performance are expensive when compared to oil-containing products with the same lubricity performance. The reduced physical lubricity of the synthetic product as a function of the cost of the semi-synthetic product limits the use of the synthetic product in heavy duty operation.

It is not intended to limit the scope.

実施例１

Figure 0005704921
Example 1
Figure 0005704921

第１表中の材料Ａ〜Ｅを、６０６１アルミニウムのタッピングを含むタッピングトルク操作に使用した。前記の濃厚物を最初に試験前に７．５体積％の溶液に希釈した。タッピングトルク試験は、金属加工流体の潤滑度性能を定量的に測定することである。このタッピングトルク試験は、Ｄ５６１９に示されたＡＳＴＭ標準法を有する。タッピングトルクは、通常２つの金属表面を一緒に摩擦することによって実施される他の試験よりも良好に工業的な機械加工処理に影響を及ぼす。このタッピングトルクは、金属加工流体（ＭＷＦ）製品の機械加工性能を実験室内で識別する優れた方法である。タッピングトルクの結果は、現場での機械加工性能と十分に相互関係を有することを証明した。   Materials A to E in Table 1 were used for tapping torque operations including 6061 aluminum tapping. The concentrate was first diluted into a 7.5% by volume solution prior to testing. The tapping torque test is a quantitative measurement of the lubricity performance of a metal working fluid. This tapping torque test has the ASTM standard method shown in D5619. Tapping torque affects industrial machining processes better than other tests typically performed by rubbing two metal surfaces together. This tapping torque is an excellent way to identify the machining performance of a metalworking fluid (MWF) product in a laboratory. The tapping torque results proved to be well correlated with on-site machining performance.

このタッピングトルク計測器は、実際の切削が実施される一方で、ＭＷＦｓの潤滑度を測定するように設計されている。タッピング操作中に、タッピングトルク計測器は、瞬間トルク２５０回を切削深さを通してのタップの進みとして測定する。更に、特殊化されたソフトウェアは、データ分析を簡易化する。タッピングトルクは、Ｎ−ｍ（ニュートン−メートル）またはＮ−ｃｍ（ニュートン−センチメートル）の単位で表現される。高い潤滑度を有する製品は、低いトルク値を発生させるであろう。反対に、低い潤滑度の製品は、高いトルク値を発生させるであろう。こうして、前記計測器は、製品間の潤滑性能の差を定量化する。   This tapping torque measuring instrument is designed to measure the lubricity of MWFs while actual cutting is performed. During the tapping operation, the tapping torque meter measures 250 instantaneous torques as tap progress through the cutting depth. In addition, specialized software simplifies data analysis. The tapping torque is expressed in units of Nm (Newton-meter) or N-cm (Newton-centimeter). Products with high lubricity will generate low torque values. Conversely, a low lubricity product will produce a high torque value. Thus, the instrument quantifies the difference in lubrication performance between products.

タッピングトルク計測器の１つの欠点は、測定された絶対トルク値が使用されたタップの直径に依存し、この直径で変動しうることにある。それ故に、前記の幾何学的効果を取り消すために、潤滑度を単位面積当たりのトルクとして表現することは、効果的であり、１回のタップが１回転するエネルギーが記載される。このための数式は、
Ｅ/Ａ ＝ （２’ｒ）／ｒ２
であり、
上記式中、ｔ＝トルク値、ｒ＝タップの半径、Ｅ／Ａ＝単位面積当たりのエネルギー量であり、単位は、Ｎ−ｍ-1（１メートル当たりのニュートン）またはＮ−ｃｍ-1（１センチメートル当たりのニュートン）である。 One drawback of the tapping torque meter is that the measured absolute torque value depends on the diameter of the tap used and can vary with this diameter. Therefore, it is effective to express the degree of lubrication as torque per unit area in order to cancel the geometric effect, and the energy for one rotation of one tap is described. The formula for this is
E / A = (2'r) / r2
And
In the above formula, t = torque value, r = radius of tap, E / A = energy amount per unit area, and the unit is Nm -1 (Newton per meter) or N-cm -1 ( Newton per centimeter).

潤滑度のデータは、第１表中に表されており、Ｅ／Ａとして識別される。Ｅ／Ａ値が低くなると、潤滑度および機械加工の性能は、良好になる。全ての試料は、試験前に水で７．５体積％に希釈されていた。   Lubricity data is presented in Table 1 and is identified as E / A. The lower the E / A value, the better the lubricity and machining performance. All samples were diluted to 7.5% by volume with water prior to testing.

実施例２：
第１表の材料は、ナノメートル単位での体積平均径の測定を含めて粒径の操作に使用された。前記の濃厚物を最初に水で試験前に７．５体積％の溶液に希釈した。粒径計測器は、高性能動的光散乱を使用し、２０〜１０００００ナノメートルの粒径を定量化する。 Example 2:
The materials in Table 1 were used for particle size manipulation, including measurement of volume average diameter in nanometers. The concentrate was first diluted with water to a 7.5% by volume solution prior to testing. The particle sizer uses high performance dynamic light scattering to quantify a particle size of 20-100,000 nanometers.

全ての試料は、試験前に７．５体積％に希釈されていた。生じる粒径は、第１表中に示されている。   All samples were diluted to 7.5% by volume prior to testing. The resulting particle size is shown in Table 1.

実施例３
第１表からの材料Ｃを２つの異なる濃度で粒径について試験し、それぞれの濃度で外観およびエマルジョン安定性について評価した。結果は、第２表中に示されており、これは、大きな平均粒径、不透明の外観およびそれぞれの濃度での優れた安定性を示す。大きな粒径は、よりいっそう良好な潤滑剤の特性を示す。典型的な合成ＭＷＦｓは、希釈した際に、１００ナノメートル未満の粒径を有する澄明な溶液を形成する。希釈された試料Ｃは、典型的な合成ＭＷＦｓで見られる最大粒径よりも３．５〜２０倍大きい粒径を有する。 Example 3
Material C from Table 1 was tested for particle size at two different concentrations and evaluated for appearance and emulsion stability at each concentration. The results are shown in Table 2, which shows a large average particle size, opaque appearance and excellent stability at each concentration. Larger particle sizes indicate even better lubricant properties. Typical synthetic MWFs form a clear solution having a particle size of less than 100 nanometers when diluted. Diluted Sample C has a particle size that is 3.5-20 times larger than the maximum particle size found in typical synthetic MWFs.

実施例１〜３から、最適な潤滑度および粒径は、カルボン酸アルカリ金属塩１０％とＰｌｕｒｏｎｉｃ "Ｒ"ブロックコポリマー２０％とを組み合わせた試料Ｃで得られることが判明する。この割合は、最大の体積平均径および最大の潤滑度を生じる。   Examples 1-3 show that optimum lubricity and particle size are obtained with Sample C, which combines 10% alkali metal carboxylate and 20% Pluronic "R" block copolymer. This ratio yields the maximum volume average diameter and maximum lubricity.

また、前記実施例から、主に、組成物の潤滑度は、体積平均径の関数であることが明らかになる。体積平均径の増加は、潤滑度の増加を生じる。   Also, from the above examples, it becomes apparent that the lubricity of the composition is a function of the volume average diameter. An increase in volume average diameter results in an increase in lubricity.

実施例３から、試料Ｃの増加した濃度は、著しく大きな体積平均径を生じることが判明する。これは、試料Ｃの高い濃度を安定化するために乳化剤が必要であることを説明するものである。乳化剤なしの場合には、高い濃度の粒径により、不安定な状態で凝集が連続されることは、確実である。本明細書中に記載された現在の好ましい実施態様に対する種々の変更および変形は、当業者にとっては明らかなことであると理解されるべきである。このような変更および変形は、本発明の精神および範囲を逸脱することなく、意図した利点を減少させることなく形成させることができる。それ故に、このような変更および変形は、係属された請求項の記載によって網羅されることが意図される。   From Example 3, it can be seen that the increased concentration of Sample C results in a significantly larger volume average diameter. This explains the need for an emulsifier to stabilize the high concentration of Sample C. In the absence of an emulsifier, it is certain that agglomeration continues in an unstable state due to the high concentration of particle size. It should be understood that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the invention and without diminishing its intended advantages. Accordingly, such modifications and variations are intended to be covered by the appended claims.
