上記R3、R5及びR6の数平均分子量が500未満であると、基油への溶解性が低下し、3,000を超えると、清浄性が低下し、目的の性能が得られないおそれがある。また、上記rは、好ましくは2〜5、より好ましくは3〜4である。rが1未満であると、清浄性が悪化し、rが10を上回ると、基油に対する溶解性が悪くなる。
一般式(III)において、sは好ましくは1〜4、より好ましくは2〜3である。sが0であると、清浄性が悪化し、sが10を上回ると、基油に対する溶解性が悪くなる。アルケニル基としては、ポリブテニル基、ポリイソブテニル基、エチレン−プロピレン共重合体を挙げることができ、アルキル基としてはこれらを水添したものである。
好適なアルケニル基の代表例としては、ポリブテニル基又はポリイソブテニル基が挙げられる。ポリブテニル基は、1−ブテンとイソブテンの混合物あるいは高純度のイソブテンを重合させたものとして得られる。また、好適なアルキル基の代表例としては、ポリブテニル基又はポリイソブテニル基を水添したものである。
上記のモノタイプのコハク酸イミド化合物及びビスタイプのコハク酸イミド化合物は、アルケニルコハク酸無水物若しくはアルキルコハク酸無水物とポリアミンとの反応比率を変えることによって製造することができる。
上記ポリオレフィンを形成するオレフィン単量体としては、炭素数2〜8のα−オレフィンの一種又は二種以上を混合して用いることができるが、イソブテンとブテン−1の混合物を好適に用いることができる。
一方、ポリアミンとしては、エチレンジアミン,プロピレンジアミン,ブチレンジアミン,ペンチレンジアミン等の単一ジアミン、ジエチレントリアミン,トリエチレンテトラミン,テトラエチレンペンタミン,ペンタエチレンヘキサミン、ジ(メチルエチレン)トリアミン、ジブチレントリアミン、トリブチレンテトラミン、ペンタペンチレンヘキサミン等のポリアルキレンポリアミン、アミノエチルピペラジン等のピペラジン誘導体を挙げることができる。
例えば、上記のポリオレフィンを無水マレイン酸と反応させてアルケニルコハク酸無水物とした後、更に上記のポリアミンと酸化ホウ素、ハロゲン化ホウ素、ホウ酸、ホウ酸無水物、ホウ酸エステル、ホウ素酸のアンモニウム塩等のホウ素化合物を反応させて得られる中間体と反応させてイミド化させることによって得られる。
このホウ素誘導体中のホウ素含有量には特に制限はないが、ホウ素として、通常0.05〜5質量%、好ましくは0.1〜3質量%である。
これら粘度指数向上剤の配合量は、配合効果の点から、潤滑油組成物全量基準で、通常0.5〜15質量%程度であり、好ましくは1〜10質量%である。
本発明において金属系清浄剤としては、上記の中性塩、塩基性塩、過塩基性塩及びこれらの混合物等を用いることができ、特に過塩基性サリチレート、過塩基性フェネート、過塩基性スルフォネートの1種以上と中性スルフォネートとの混合が清浄性、耐摩耗性において好ましい。
6価のモリブデン化合物と反応させるアミン化合物としては特に制限されないが、具体的には、モノアミン、ジアミン、ポリアミン及びアルカノールアミンが挙げられる。より具体的には、メチルアミン、エチルアミン、ジメチルアミン、ジエチルアミン、メチルエチルアミン、メチルプロピルアミン等の炭素数1〜30のアルキル基(これらのアルキル基は直鎖状でも分枝状でもよい)を有するアルキルアミン;エテニルアミン、プロペニルアミン、ブテニルアミン、オクテニルアミン、及びオレイルアミン等の炭素数2〜30のアルケニル基(これらのアルケニル基は直鎖状でも分枝状でもよい)を有するアルケニルアミン;メタノールアミン、エタノールアミン、メタノールエタノールアミン、メタノールプロパノールアミン等の炭素数1〜30のアルカノール基(これらのアルカノール基は直鎖状でも分枝状でもよい)を有するアルカノールアミン;メチレンジアミン、エチレンジアミン、プロピレンジアミン、及びブチレンジアミン等の炭素数1〜30のアルキレン基を有するアルキレンジアミン;ジエチレントリアミン、トリエチレンテトラミン、テトラエチレンペンタミン、ペンタエチレンヘキサミン等のポリアミン;ウンデシルジエチルアミン、ウンデシルジエタノールアミン、ドデシルジプロパノールアミン、オレイルジエタノールアミン、オレイルプロピレンジアミン、ステアリルテトラエチレンペンタミン等の上記モノアミン、ジアミン、ポリアミンに炭素数8〜20のアルキル基又はアルケニル基を有する化合物やイミダゾリン等の複素環化合物;これらの化合物のアルキレンオキシド付加物;及びこれらの混合物等が例示できる。また、特公平3−22438号公報及び特開2004−2866公報に記載されているコハク酸イミドの硫黄含有モリブデン錯体等が例示できる。
リン含有量は0.12質量%以下であることが好ましい。リン含有量が0.12質量%以下であれば、排出ガスを浄化する触媒の性能低下を抑えることができ、より好ましいリン含有量は0.1質量%以下である。
また、硫酸灰分は1質量%以下であることが好ましい。硫酸灰分が1質量%以下であれば、前記と同様に、排出ガスを浄化する触媒の性能低下を抑えることができる。また、ディーゼルエンジンにおいては、DPF(ディーゼルパティキュレートフィルター)のフィルタに堆積する灰分量が少なく、該フィルタの灰分詰まりが抑制され、DPFの寿命が長くなる。なお、この硫酸灰分とは、試料を燃やして生じた炭化残留物に硫酸を加えて加熱し、恒量にした灰分をいい、通常潤滑油組成物中の金属系添加剤の大略の量を知るために用いられる。
上記の内燃機関の摺動部材は特に問われず、本発明の潤滑油組成物は、鉄、鋼、鋳鉄、ボロン鋳鉄、アルミニウム、銅、すず、鉛等の金属材料からなる摺動面やダイヤモンドライクカーボン(DLC)、窒化チタン(TiN)、窒化クロム(CrN)等の硬質皮膜を有する摺動面において適用できる。これらの摺動部材は同種の組み合わせ、または異種の組み合わせのどちらでもよいが、少なくとも一方が硬質皮膜面であることが好ましい。

〔硫酸灰分〕
JIS K2272に準拠して測定した。
本発明品の摩擦特性は往復動摩擦摩耗試験機を用いて評価した。試験板はボロン鋳鉄、を使用し、試験球は硬質クロムメッキ処理、窒化処理、窒化クロム(PVD)処理およびDLC(水素20%含有)処理のいずれかの処理を施したSUJ−2 1/2インチ球を用いた。試験温度100℃、荷重200g、振幅10mm、摺動速度1.0mm/secで試験を実施し、得られた摩擦係数を省燃費性の指標とした。
摩擦係数低減率は、摩擦調整剤無添加サンプル(比較例1)における摩擦係数を基準にして、以下の式により求めた。
摩擦係数低減率(%)=[比較例1の摩擦係数]−[実施例または比較例における摩擦係数]/[比較例1の摩擦係数]×100
ガラス製試験管に、試料120g、銅(25mm×10mm×0.5mm)、鉄(25mm×30mm×0.5mm)を加え、165.5℃にて空気(500ml/分)を吹き込み酸化劣化させた。216時間後に40℃における動粘度を測定し、粘度増加比率を求めた。また試験油中の銅量を測定した。粘度増加が少ないほど酸化安定性に優れていることを示す。また銅の溶出量が少ないほど銅に対する影響が少なく、金属材料への特性が優れていることを示す。
ガラス製試験管に、試料40g、鉛(10mm×10mm×1.0mm)を浸漬させ140℃にて腐食試験を行った。144時間後の鉛量を測定し、鉛に対する腐食の影響をみた。鉛の溶出量が少ないほど、鉛に対する影響が少なく、金属材料への特性が優れていることを示す。
また、(A)成分および(B)成分の含有量と摩擦係数低減効果の関係は、実施例1、2および比較例6から示される。実施例1、2と比べて、比較例6においてはその添加量に見合った効果が得られていない。さらに比較例6においては、潤滑油組成物の酸化劣化および鉛腐食性において高い値を示しており、(A)成分と(B)成分を加える弊害が目立つ結果となっている。
また実施例2および比較例7で示されるように、(C)ベンゾトリアゾール化合物の添加により、さらにこの酸化劣化および鉛腐食性の抑制が達成されている。
さらに実施例1〜5と比較例8を比較すると、鉛腐食試験および酸化劣化試験において比較例8は大幅に劣る結果となっている。これはイミド化合物の相違に起因するものと考えられ、(d1)数平均分子量1500以上のポリブテニル基を含有するポリブテニルコハク酸ビスイミド化合物の含有量に関する(D)コハク酸イミド化合物全量に対する規定や、(d1)成分の窒素量に関する(D)コハク酸イミド化合物の総窒素量に対する規定によって得られた効果である。
