Description
有機モリブデン化合物を配合したエンジン油は、使用初期においては優れた潤滑性を示す。しかし、エンジン油の劣化とともに潤滑性が低下し、長期間使用すると有機モリブデン化合物を配合していないエンジン油と同等の潤滑性しか示さなくなるという問題がある。このため、有機モリブデン化合物の分解を遅らせ、潤滑性を長期間維持できる組成物の開発が望まれている。有機モリブデン化合物の分解を遅らせるにはエンジン油の酸化防止性を向上させることが有効であり、芳香族成分の多い基油(例えば、特許文献4、5を参照)はパラフィン成分の多い基油よりも酸化防止性が高く、フェノール系酸化防止剤やアミン系酸化防止剤、亜鉛ジチオフォスフェート化合物等の酸化防止性を有する化合物を配合する方法(例えば、特許文献6~8を参照)が知られている。
