Abstract
Description
本発明は、水溶性金属加工用潤滑剤に関し、詳しくは、アルミ等の非鉄金属と鋼等の鉄金属のいずれの金属加工においても好適に利用できる水溶性金属加工用潤滑剤に関するものである。 The present invention relates to a water-soluble metal processing lubricant, and more particularly to a water-soluble metal processing lubricant that can be suitably used in any metal processing of non-ferrous metals such as aluminum and iron metals such as steel.
近年、自動車を軽量化することによる燃費向上を達成するために、自動車の製造に使用される材料としてアルミニウムの量が増加してきている。このような変化は、自動車の製造に於いては、従来から用いられている鋼等の鉄金属の部品とともに、アルミニウムやその合金等の非鉄金属の部品も成型加工する金属加工設備や金属加工工程が必要になっていることを示している。
ところが、プレス加工等の金属加工に用いられる金属加工用潤滑剤は、通常被加工材の種類によって異なる潤滑剤を使用する。例えば、被加工材が非鉄金属である場合と鉄金属である場合とでは、金属加工用潤滑剤に要求される加工性能が相違するため、通常それぞれ異なる油剤が用いられる。つまり、非鉄金属用油剤を鉄金属の加工油剤として使用したり、鉄金属用油剤を非鉄金属の金属加工に使用すると、それらの成型加工品は、必ずしも満足できるものではない結果となる。
In recent years, the amount of aluminum has been increasing as a material used in the manufacture of automobiles in order to achieve improved fuel economy by reducing the weight of the automobile. Such changes in the manufacture of automobiles include metal processing equipment and metal processing processes that form and process non-ferrous metal parts such as aluminum and its alloys, as well as steel and other conventional metal parts. Indicates that it is necessary.
However, as a metal working lubricant used for metal working such as press working, a different lubricant is usually used depending on the type of workpiece. For example, when the workpiece is a non-ferrous metal and when it is a ferrous metal, the processing performance required for the metal processing lubricant is different, and therefore different oil agents are usually used. In other words, when a non-ferrous metal oil is used as a ferrous metal processing oil or a ferrous metal oil is used for non-ferrous metal processing, these molded products are not always satisfactory.
このような状況から、自動車製造等の非鉄金属と鉄金属の両者を金属加工する工場においては、鉄金属用の加工設備(加工ライン)と非鉄金属用の加工設備を別々に設置することが必要である。そのために必要な設備や設備費が増加するとともに、作業効率が低下してしまうという問題がある。
このような問題を解決するためには、被加工材が非鉄金属であっても鉄金属であっても良好な加工性能(成型性)を示す油剤を開発することが必要である。そのような油剤があれば、鉄金属と非鉄金属を共通の加工設備(加工ライン)で加工することが可能になる。
Under these circumstances, in factories that process both non-ferrous metals and ferrous metals, such as automobile manufacturing, it is necessary to install processing facilities for ferrous metals (processing lines) and processing facilities for non-ferrous metals separately. It is. Therefore, there are problems that necessary facilities and facility costs increase and work efficiency decreases.
In order to solve such problems, it is necessary to develop an oil agent that exhibits good processing performance (moldability) regardless of whether the workpiece is a non-ferrous metal or an iron metal. With such an oil agent, it is possible to process ferrous metal and non-ferrous metal with a common processing facility (processing line).
また、金属加工においては、上記加工性能が優れるとともに、それ以外の種々の性能を満たすことが要求される。例えば自動車部品の製造においては、接着剤との適合性、つまり金属加工製品(部品)同士又は金属加工製品と他の材料部品とを接着して組み立てるため、それらの間の接着性が優れることを要求される。したがって、良好な接着性(接着適合性)が不可欠である。
さらに、金属加工油剤は、防錆性、脱脂性、貯蔵安定性などの基本的性能も当然要求されている。
Further, in metal processing, it is required that the above processing performance is excellent and various other performances are satisfied. For example, in the manufacture of automobile parts, compatibility with adhesives, that is, because metal processed products (parts) or metal processed products and other material parts are assembled and assembled, the adhesion between them is excellent. Required. Therefore, good adhesion (adhesion compatibility) is essential.
Furthermore, the metal processing oil is naturally required to have basic performance such as rust prevention, degreasing, and storage stability.
本発明は、上述のような状況下でなされたものであり、アルミニウム等の非鉄金属と鉄や鋼等の鉄金属のいずれの金属加工においても加工性能が優れ、同時に接着剤との適合性が良好な水溶性金属加工用潤滑剤を提供することを目的とするものである。 The present invention has been made under the circumstances as described above, and has excellent processing performance in both metal processing of non-ferrous metals such as aluminum and ferrous metals such as iron and steel, and at the same time compatibility with adhesives.

本発明の水溶性金属加工用潤滑剤は、プレス加工等種々の金属加工に有効であり、特に、アルミニウム等の非鉄金属と鉄や鋼等の鉄金属のいずれの金属加工においても加工性能に優れている。また、接着剤の適合性にも優れる水溶性金属加工用潤滑剤である。
したがって、自動車の部品製造など多種の被加工材を加工する金属加工用潤滑剤として有効に利用することができる。
The lubricant for water-soluble metal processing of the present invention is effective for various metal processing such as press processing, and is particularly excellent in processing performance in any metal processing of non-ferrous metals such as aluminum and iron metals such as iron and steel. ing. In addition, it is a water-soluble metal processing lubricant with excellent adhesive compatibility.
Therefore, it can be effectively used as a lubricant for metal processing for processing various workpieces such as automobile parts manufacturing.
