Abstract
Description
本発明は、塑性加工用潤滑油組成物に関する。詳しくは、加工時の温度が２００℃以上の難加工と位置づけられる冷間塑性加工において好適な塑性加工用潤滑油組成物に関する。 The present invention relates to a lubricating oil composition for plastic working. Specifically, the present invention relates to a lubricating oil composition for plastic working that is suitable for cold plastic working, which is positioned as difficult working with a processing temperature of 200 ° C. or higher.
これまでに切削加工や塑性加工等の金属加工においては塩素系極圧剤が切削性やプレス加工性向上効果に優れ、かつ安価なため多用されてきた。しかし、近年では塩素系極圧剤を配合した潤滑油は、焼却処理時のダイオキシンの発生や焼却炉の腐食・損傷等の問題が指摘されている。また、一部の有機塩素化合物は、発がん性を有することも報告されている。したがって、塩素を含有しない金属加工油の開発が進められてきた。塩素を含有しない金属加工油としては、硫化オレフィン、硫化油脂、カルシウムスルホネート、ＺｎＤＴＰ等の硫黄基材や、リン酸エステル等のリン系基材を使用したものが、従来から知られている（特許文献１〜３参照）。そして工具と材料の面圧が高く、摩擦面温度が高い場合、硫黄系極圧剤を中心に上記添加剤を多量に添加する必要がある。 So far, in metal working such as cutting and plastic working, chlorinated extreme pressure agents have been widely used because they are excellent in cutting performance and press workability improving effect and are inexpensive. In recent years, however, lubricating oils containing chlorinated extreme pressure agents have been pointed out as problems such as generation of dioxins during incineration and corrosion / damage of incinerators. Some organochlorine compounds have also been reported to have carcinogenicity. Accordingly, development of metalworking oils that do not contain chlorine has been underway. As metal processing oils that do not contain chlorine, those using sulfur base materials such as sulfurized olefins, sulfurized fats and oils, calcium sulfonate, ZnDTP, and phosphorus base materials such as phosphate esters have been known (patents). References 1-3). When the surface pressure of the tool and the material is high and the friction surface temperature is high, it is necessary to add a large amount of the above-mentioned additive mainly in the sulfur-based extreme pressure agent.
通常の冷間板成形における加工部位の温度は、非特許文献１では室温〜１５０℃とされている。一方、冷間しごき加工や引抜き加工では室温〜３００℃とされている。よって加工部位の温度が２００℃以上の場合、難加工と位置づけられる。加工部位の温度が２００℃以上の場合、塑性加工油の動粘度（４０℃）が８０ｍｍ２／s未満の場合、焼付きなどの加工不良が発生してしまう。一方、ハンドリング性の点から動粘度（４０℃）の上限は２５０ｍｍ２／ｓ程度である。一般的な硫化油脂はおよそ２００〜１０００ｍｍ２／ｓで、加えてカルシウムスルホネートを代表とする金属系清浄剤は４００ｍｍ２／ｓ〜１０００ｍｍ２／ｓで両者の併用は限定的となる。そのため同じ硫黄系極圧剤でも動粘度が１０〜１００ｍｍ２／ｓ程度のポリサルファイドを多用する。 In non-patent document 1, the temperature of the processed part in normal cold plate forming is set to room temperature to 150 ° C. On the other hand, in cold ironing and drawing, the temperature is set to room temperature to 300 ° C. Therefore, when the temperature of a processing part is 200 degreeC or more, it is positioned as a difficult process. When the temperature of the processing site is 200 ° C. or higher, processing defects such as seizure occur when the kinematic viscosity (40 ° C.) of the plastic processing oil is less than 80 mm 2 / s. On the other hand, the upper limit of kinematic viscosity (40 ° C.) is about 250 mm 2 / s from the viewpoint of handling properties. Typical sulfurized fats at approximately 200 to 1000 mm 2 / s, in addition metallic detergents typified by calcium sulfonate with the combination of the both in 400mm 2 / s~1000mm 2 / s is limited. Therefore, polysulfide having a kinematic viscosity of about 10 to 100 mm 2 / s is frequently used even with the same sulfur-based extreme pressure agent.
本発明はこのような事情を鑑みてなされたものであり、加工部位の温度が２００℃以上の難加工と位置づけられる塑性加工において硫黄系極圧剤の中で比較的動粘度の低いポリサルファイドで分子構造を限定し、最も優れる塑性加工用潤滑油組成物を提供することを目的とする。 The present invention has been made in view of such circumstances, and is a polysulfide and molecular molecule having a relatively low kinematic viscosity in a sulfur-based extreme pressure agent in plastic processing, which is positioned as difficult processing at a processing site temperature of 200 ° C. or higher. The object is to provide the most excellent lubricating oil composition for plastic working by limiting the structure.
本発明者らは前記課題について鋭意研究した結果、本発明を完成するに至った。 As a result of intensive studies on the above problems, the present inventors have completed the present invention.
すなわち、本発明は、鉱油、油脂および合成油からなる群より選ばれる少なくとも一種の基油と、分子構造が式（１）で表わされるポリサルファイドを２０質量％以上含有し、組成物の４０℃における動粘度が８０〜２５０ｍｍ２／ｓである塑性加工用潤滑油組成物である。
また、本発明は、さらに金属比１以上３０以下の金属系清浄剤を含有することを特徴とする前記の塑性加工用潤滑油組成物である。 Further, the present invention is the above-described lubricating oil composition for plastic working, further comprising a metal detergent having a metal ratio of 1 to 30.

Lubricating oil was applied to both surfaces of the test piece with a waste impregnated with an oil agent so as to be 1 to 2 g / m 2 and subjected to the test. Judgment of the performance of the lubricating oil is made by visually checking the damaged state of the ball after the test. The determination is as follows, and a determination of Δ or higher is accepted. However, in the case of lubricating oil with extremely low performance, the ball does not penetrate the stainless steel plate and breaks.
