Description
すなわち、本発明のエスカレータ用チェーンオイルは、鉱油、油脂および合成油の中から選ばれる少なくとも1種を基油として、組成物全量基準で、(A)重量平均分子量が25万〜60万のポリイソブチレンを0.01〜5質量%と(B)フェノール系酸化防止剤を0.01〜3質量%含有してなることを特徴とする。
本発明のエスカレータ用チェーンオイルに用いられる潤滑油基油としては、鉱油、油脂および合成油の中から選ばれる少なくとも1種が用いられる。
また、0℃における動粘度も任意であるが、滴下給油性等の点から、通常2,000mm2/s以下であることが好ましく、1,600mm2/s以下であることがより好ましい。
また、基油の粘度指数は特に制限されないが、80以上が好ましく、より好ましくは100以上、更に好ましくは120以上、最も好ましくは130以上である。粘度指数が高いほど高温での粘度が高いため、高温での油膜強度が強く、チェーンに貼り付きやすい。また粘度指数が高い合成油は、低温粘度が低く、滴下給油性に優れている。
さらに基油の流動点も任意であるが、滴下給油性等の点から、通常、その流動点は、好ましくは−5℃以下、より好ましくは−15℃以下である。
これら基油の中でも、より粘度指数が高い点から合成油を用いることが好ましい。合成油の中でも、着色が少なく、酸化安定性に優れたポリα−オレフィン(エチレンープロピレン共重合体、ポリブテン、1−オクテンオリゴマー、およびこれらの水素化物等)、アルキルベンゼン、アルキルナフタレンなどの炭化水素系合成油が好ましい。
R2で表される炭素数1〜18のアルキル基としては、具体的には、メチル基、エチル基、プロピル基、ブチル基、ペンチル基、ヘキシル基、ヘプチル基、オクチル基、ノニル基、デシル基、デシル基、ウンデシル基、ドデシル基、トリデシル基、テトラデシル基、ペンタデシル基、ヘキサデシル基、ヘプタデシル基、及びオクタデシル基等(これらアルキル基は直鎖状でも分枝状でもよい)等が例示できる。
