Abstract
Description
(1)前記(B)成分における官能基が、カルボキシル基、エステル基、無水カルボキシル基、水酸基、グリシジル基、及びアミノ基から選ばれる。
(2)前記官能基が水酸基である。
(3)(C)リン系摩耗防止剤及びリン系極圧剤から選ばれる少なくとも1種をさらに含む。
(4)前記(C)リン系摩耗防止剤が、ジアルキルジチオリン酸亜鉛である。
(5)前記(C)リン系極圧剤が、リン酸エステル、亜リン酸エステル、チオリン酸エステル、チオ亜リン酸エステル、酸性リン酸エステル、酸性亜リン酸エステル、チオ酸性リン酸エステル、チオ酸性亜リン酸エステル及びこれらのアミン塩よりなる群から選択される少なくとも1種である。
(6)さらに(D)硫黄系極圧剤を含む。
(7)さらに(E)無灰分散剤を含む。
(8)(A)潤滑油基油が100℃での動粘度1〜4mm2/sを有する。
(9)自動車用ギヤ油である。
(10)自動車用変速機油である。
(11)ハイブリッド自動車用変速機油である。
本発明における潤滑油基油は従来公知の潤滑油基油であればよく、鉱油、合成油、あるいはこれらの混合油がある。潤滑油基油の動粘度は限定的ではないが、100℃での動粘度1〜4mm2/sを有するのが好ましい。
(B)成分は、ポリジエンの分子鎖の少なくとも1の末端が官能基の導入により変性されたものである(以下、末端変性ポリジエンということがある)。ポリジエンとは、単量体ジエンを(共)重合して得られたものであり、飽和ポリジエンとは、前記のようにして得られたポリジエンの炭素−炭素二重結合が水素化により飽和された水素化物である。本発明の潤滑油組成物は該末端変性ポリジエンを含むことを特徴とする。当該末端変性ポリジエンは、末端変性不飽和ポリジエンであってもよいし、末端変性飽和ポリジエンであってもよい。なお、潤滑油基油への溶解性の観点からは、末端変性飽和ポリジエンを使用することが好ましい。官能性基を有するポリジエンは、摺動面に吸着し、部分的に組成物を高粘度化させて、潤滑油組成物の油膜厚さを厚くする。これにより、低粘度化した潤滑油組成物における、ギア歯面やベアリングの金属疲労や摩耗を抑制し、部品保護性能を向上することができる。
上記末端変性飽和ポリジエンは、市場において適合するものを選択し、入手することができる。
本発明の潤滑油組成物は、好ましくは、リン系摩耗防止剤及びリン系極圧剤から選択される少なくとも1種(以下、リン系添加剤ということがある)を含有する。該(C)成分の量は、好ましくは、潤滑油組成物全体の質量に対するリン原子の合計含有量が50〜500質量ppmとなる量であるのがよく、より好ましくは80〜450質量ppmとなる量、さらに好ましくは100〜400質量ppmとなる量、特に好ましくは120〜400質量ppmとなる量であるのがよい。リン系添加剤の量を上記範囲とすることにより、得られる潤滑油組成物は、低粘度化しても、優れた金属疲労寿命、耐摩耗性、及び電気絶縁性の維持をより確実にすることができる。
本発明の潤滑油組成物は、任意で、硫黄系極圧剤をさらに含んでいてよい。硫黄系極圧剤は公知のものであればよいが、好ましくは、硫化オレフィンに代表されるスルフィド化合物、硫化油脂に代表される硫化エステルから選ばれる少なくとも1種である。特には硫化オレフィンが好ましい。
硫化オレフィンとしては、例えば、ポリイソブチレン類及びテルペン類などのオレフィン類を、硫黄または他の硫化剤で硫化して得られるものが挙げられる。
本発明の潤滑剤組成物はさらに無灰分散剤を含有することができる。無灰分散剤は従来公知のものを使用すればよく、特に制限されるものでない。例えば、炭素数40〜400の、直鎖構造又は分枝構造を有するアルキル基又はアルケニル基を分子中に少なくとも1個有する含窒素化合物又はその誘導体、あるいはコハク酸イミド及びその変性品等が挙げられる。無灰分散剤は1種類を単独で使用しても、2種類以上を併用してもよい。また、ホウ素化無灰分散剤を使用することもできる。ホウ素化無灰分散剤は潤滑油に用いられている任意の無灰分散剤をホウ素化したものである。ホウ素化は一般に、イミド化合物にホウ酸を作用させて、残存するアミノ基及び/又はイミノ基の一部又は全部を中和することにより行われる。
モノタイプのコハク酸イミド化合物は例えば下記式(5)で表すことができる。ビスタイプのコハク酸イミド化合物は例えば下記式(6)で表すことができる。
使用する基油と添加剤は、以下のとおりである。
(A)潤滑油基油 鉱油(高度分解精製基油、100℃の動粘度;3mm2/s、粘度指数;122、グループIII基油)
(B)ポリジエン化合物
(B1)両末端水酸基含有飽和ポリブテン(数平均分子量(Mn)1000)
(B2)両末端水酸基含有飽和ポリブテン(数平均分子量(Mn)3000)
(B3)両末端カルボキシル基含有飽和ポリブテン(数平均分子量(Mn)1000)
(B4)両末端水酸基含有不飽和ポリブテン(数平均分子量(Mn)1000)
(B5)末端未変性飽和ポリブテン(数平均分子量(Mn)3000)(比較用)
(B6)両末端ウレタン基含有飽和ポリブテン(数平均分子量(Mn)1000)
(C)リン系添加剤
ジアルキルジチオリン酸亜鉛(摩耗防止剤、2級アルキル、2−エチルヘキシル基)
(D)硫黄系極圧剤:硫化エステル(硫黄含有量=10質量%)
(E)無灰分散剤:ポリブテニルコハク酸ビスイミド、ポリブテニル基分子量=3000、窒素含有量=1.0質量%、ホウ素含有量=0.5質量%
(F) その他の添加剤
酸化防止剤(ジフェニルアミン)、金属不活性化剤、消泡剤
(G)粘度指数向上剤(比較用)
ポリメタクリレート、重量平均分子量50,000、ポリマー量;50質量%
上記した各成分を表1に記載の組成及び量で混合して潤滑油組成物を調製した。
表に記載の各量について、以下に説明する。
リン系極圧剤の量は、潤滑油組成物の総量に対するリンの質量ppmである。ポリブテン、硫黄系極圧剤、分散剤、粘度指数向上剤、その他の添加剤の量は、各々、潤滑油組成物の総量に対する質量%である。基油の量は潤滑油組成物の総量100とした残部である。
(1) 動粘度(100℃)は、ATSM D445に準拠して測定した。
(2) 金属疲労特性
内径19.2mm,外径28.5mm,ニードル径2mmのスラストニードルベアリングを使用した単体試験であって、付加スラスト荷重 10.5N、回転数3000rpm、油温120℃とし、金属疲労発生までのサイクル数を計測した。
(3) 耐摩耗性は、ASTM D4172−2に準拠して測定した。
(4) 電気絶縁性(体積抵抗率)は、JIS C2101に準拠して測定した。
(5) 潤滑油基油へのポリジエン化合物の溶解性
溶液が透明である場合に○、溶液が透明ではないが物性測定には影響がない場合は△、溶液が濁っていて物性測定が不可能である場合を×とした。
なお、ポリジエン化合物の溶解性が悪い場合は、その他の物性値の測定を行わなかった。また、100℃の動粘度が5mm2/sを超えている場合も、その他の物性値の測定を行わなかった。
一方、比較例1に示す通り、所定のポリジエン化合物の添加量が十分でないと、金属疲労の面で劣る。比較例3に示す通り、末端変性が行われていないポリジエン化合物を使用すると、金属疲労及び耐摩耗性の面で劣る。このように比較例1、3の潤滑油組成物は、金属疲労特性、耐摩耗性、電気絶縁性のいずれかの特性が悪い。さらに、比較例2の潤滑油組成物は溶解性の面で問題があった。さらに、比較例4に示す通り、粘度指数向上剤を含有する潤滑油組成物は100℃の動粘度が5mm2/s超となった。比較例4の潤滑油組成物では本発明で目的とする低粘度化が達成できなかった為、その他の各物性値の測定は行っていない。
