Abstract
【解決手段】本発明に係る潤滑油組成物は、100℃の動粘度が3〜6mm2/Sの基油に、前記基油のDSCにより計測される結晶化開始温度に対して、DSCにより計測されるピークトップ温度が13℃以上低い流動性向上剤が添加されたもので、100℃動粘度が9.3〜12.5mm2/s、粘度指数が200以上、流動点が−40℃以下、引火点が200℃以上である。
【選択図】 なし
Description
使用装置:DSC6200(商品名:SII社製)
雰囲気:パージガス無し
試料量:8mg〜10mg
温度条件(熱履歴除去):50℃で2分保持した後、−60℃で2分保持し、更にその後50℃で5分保持
温度条件(評価):50℃から−60℃まで20℃/分で降温
試料容器:密封式アルミパン
比較試料:α‐酸化アルミナ
温度校正試料:Sn、In、n‐Tridecan
上記グループ1〜5の何れの基油を採用してもよいが、特にグループ1、グループ2及びグループ3基油が好ましい。
API基油カテゴリーの各基油の分類を表1に示す。
ただし、基油に対する適正な組み合わせがあり、その組み合わせを誤ると所望の効果を得られない場合がある。表2は、後述表3の基油1と基油2の混合油に、異なる流動性向上剤(後述のポリマ2、ポリマ3と同じもので、表2においてはそれぞれ流動性向上剤A、流動性向上剤Bとする)を添加した場合に得られる流動点を、流動性向上剤の添加量を変えて示したものである。表2に示すように、流動性向上剤Bを添加した場合の流動点は、添加量によらずほぼ同じとなるのに対し、流動性向上剤Aを添加した場合の流動点は、添加量の増加に伴い上がってしまう挙動が認められた。このように、流動性向上剤と組み合せる基油によっては、相乗効果や、逆の阻害効果の発現することがわかる。従って、基油に対し適切な流動性向上剤を選択する必要があり、具体的には、DSCにより計測されるピークトップ温度が、基油のDSCにより計測される結晶化開始温度に対して13℃以上低いことが必要である。
また、本発明に用いられる流動性向上剤の結晶化開始温度は−23℃以下が良く、−25℃以下がより好ましく、−27℃以下が特に好ましい。
更に、ピークトップ温度は−35℃以下が良く、−40℃以下がより好ましく、−45℃以下が特に好ましい。質量平均分子量は55,000以下が良く、54,000以下がより好ましく、53,000以下が特に好ましい。
<動粘度(@40℃)、動粘度(@100℃)>
