Description
本発明は、金属加工油組成物及び金属加工油組成物のろ過性の低下を抑制する方法に関する。 TECHNICAL FIELD The present invention relates to a metal working oil composition and a method for suppressing deterioration of filterability of the metal working oil composition.
従来、金属加工の分野では、金属製の被加工物の加工部位を潤滑するために金属加工油組成物が使用されている。例えば特許文献１には、加工性能が高いとともに、消費量を抑制でき、引火点も高い金属加工油組成物として、オレイン酸ブチルを含有する金属加工油組成物が開示されている。 Conventionally, in the field of metal working, metal working oil compositions have been used to lubricate the machining sites of metal workpieces. For example, Patent Document 1 discloses a metal working oil composition containing butyl oleate as a metal working oil composition that has high processing performance, can suppress consumption, and has a high flash point.
ところで、金属加工油組成物は、通常、複数回にわたり循環使用される。一度使用された油（使用油）は、金属加工の際に被加工物から生じた摩耗粉を含んでいるため、再度使用される前に、フィルタを用いてろ過される。しかし、従来の金属加工油組成物では、未使用の油（新油）に比べて使用油のろ過性が大幅に低下する場合があり、フィルタの目詰まりが頻繁に発生するという問題が生じ得る。 By the way, the metalworking oil composition is usually cyclically used a plurality of times. Oil that has been used once (use oil) contains abrasion powder generated from the workpiece during metal working, so it is filtered using a filter before it is used again. However, with conventional metal working oil compositions, the filterability of used oil may be significantly reduced compared to virgin oil (new oil), and the problem of frequent filter clogging may occur. .
このような問題に対し、金属加工油組成物の粘度を低くすることにより予めろ過性を高めておき、循環使用の間の濾過性を維持することは可能であるが、その場合、加工部位における油膜の保持が困難となり、加工性能が低下してしまう。したがって、金属加工油組成物の粘度が高い場合であっても、循環使用に伴うろ過性の低下を抑制することが重要である。 To address this problem, it is possible to increase the filterability in advance by lowering the viscosity of the metalworking oil composition so that the filterability can be maintained during cyclic use. It becomes difficult to maintain the oil film, and the machining performance deteriorates. Therefore, even if the viscosity of the metal working oil composition is high, it is important to suppress the decrease in filterability due to cyclic use.
本発明は、使用に伴うろ過性の低下を抑制できる金属加工油組成物を提供することを目的とする。また、本発明は、金属加工油組成物のろ過性の低下を抑制する方法を提供することを目的とする。 SUMMARY OF THE INVENTION An object of the present invention is to provide a metal working oil composition capable of suppressing deterioration of filterability due to use.

実施例及び比較例の各金属加工油組成物のろ過性を評価するために、以下に示す試験を実施した。結果を表１に示す。 In order to evaluate the filterability of each metalworking oil composition of Examples and Comparative Examples, the following tests were carried out. Table 1 shows the results.
ＡＳＴＭ Ｄ３２３３－９３（ファレックスＰ／Ｖ試験）に準拠して、２００ｌｂの負荷の下、実施例１～３及び比較例１～２の各金属加工油組成物について、５分間試験を行った。これにより、摩耗粉を含んだ金属加工油組成物（使用油）を得た。次に、この使用油１００ｍｌをミリポアフィルターによってろ過し、ろ過にかかった時間を計測した。各金属加工油組成物についてはファレックスＰ／Ｖ試験を行う前の新油についてもろ過時間を計測しておき、ろ過時間の使用油／新油の比率を求めた。使用油／新油の比率が小さいほど（例えば、１．５未満）、ろ過性の低下が抑制されているといえる。 Each of the metal working oil compositions of Examples 1-3 and Comparative Examples 1-2 were tested for 5 minutes under a load of 200 lbs according to ASTM D3233-93 (Falex P/V test). As a result, a metalworking oil composition (used oil) containing abrasion powder was obtained. Next, 100 ml of this used oil was filtered through a Millipore filter, and the time required for filtration was measured. For each metalworking oil composition, the filtration time was also measured for the new oil before the Falex P/V test was performed, and the ratio of the used oil to the new oil in the filtration time was obtained. It can be said that the lower the used oil/new oil ratio (for example, less than 1.5), the more suppressed the decrease in filterability.
