Description
(2)前記基油10〜90重量%、前記ニオブ化合物を1〜40質量%、銅化合物を1〜40質量%、並びにフッ素樹脂を1〜20質量%及び/又は炭素粉末を1〜30質量%含有してなること、
(3)前記アミド化合物、尿素化合物、及び金属石けんの中から選ばれる1種以上の化合物により半固体化されていること、
(4)前記基油に、更にモリブデン化合物、リン酸化合物、及びカルシウム系清浄剤の中から選ばれる1種以上を合計で1〜20質量%配合してなることも好ましい。なお、ここで、半固体とは、極圧潤滑剤組成物が塑性体でも液体でもないグリース状であることを指す。
また、上記基油の配合量は、10〜90質量%の範囲であり、好ましくは25〜75質量%の範囲である。極圧潤滑剤組成物中の基油の配合量が10質量%より少ないと、増ちょう剤の配合により半固体状の潤滑剤組成物とするのが難しく、一方、基油の配合量が90質量%を超えると、添加剤の配合量が少なくなるため潤滑性が不充分となる。なお、上記基油の引火点は、安全面から高いほど良く、200℃以上が好ましく、250℃以上がより好ましい。
次に示す基油、増ちょう剤、添加剤を用い、表1、2の配合に従って、実施例、比較例の潤滑剤組成物を調製した。なお、比較例6としては、市販の潤滑剤であるモリペーストAS[住鉱潤滑剤(株)製]を用いた。
・焼付き荷重:ASTM D3233を参考に、Vブロックに実施例、比較例の試料を塗布し、回転数100rpm、常温、大気中で荷重を上げ、焼付き荷重(Lbf)を測定した。
・摩耗量:ASTM D2670を参考に、Vブロックに実施例、比較例の試料を塗布し、回転数100rpm、荷重500Lbf、常温、大気中で30分摩擦させた後のピンの摩耗量(質量減、mg)を測定した。
JIS K2246(6.35中性塩水噴霧試験方法)により、実施例及び比較例の試料をJIS G3141規定の試験片(鋼板)に塗布し、温度35℃で5質量%塩水を噴霧し、90時間後の試験片(3枚)の錆発生度(平均値)を求めた。
Claims (5)
- 40℃における動粘度が32〜1000mm2/sの基油10〜90重量%、炭化ニオブであるニオブ化合物1〜40質量%、並びにアミド化合物、尿素化合物、及び金属石けんの中から選ばれる1種以上の化合物1〜50質量%を含有する油性の極圧潤滑剤組成物。
- 前記基油を10〜90重量%、前記ニオブ化合物を1〜40質量%、銅化合物を1〜40質量%、並びにフッ素樹脂を1〜20質量%及び/又は炭素粉末を1〜30質量%含有する請求項1に記載の極圧潤滑剤組成物。
- 前記アミド化合物、尿素化合物、及び金属石けんの中から選ばれる1種以上の化合物により半固体化された、請求項1又は2に記載の極圧潤滑剤組成物。
- 更にモリブデン化合物、リン酸化合物、及びカルシウム系清浄剤の中から選ばれる1種以上を合計で1〜20質量%含有する請求項1〜3のいずれかに記載の極圧潤滑剤組成物。
- 油井管ねじ継ぎ手用である、請求項1〜4のいずれかに記載の極圧潤滑剤組成物。
