Abstract
Description
また、鉛及び銅に対する耐食性を改善した特定のエポキシ化エステル化合物を含む潤滑油が提案され(特許文献2)、この特許文献2にはシクロアルキル基を含む各種のエポキシ化エステル化合物が列記されているが、具体的な化合物としては、エポキシ化トロール油脂肪酸2‐エチルヘキシルのみしか開示されておらず、また摩擦調整剤として有機モリブデン化合物を添加できるという通り一遍の記載はあるものの、その効果、特にエポキシ化合物と有機モリブデン化合物との相乗効果については何ら開示されていない。
また、本発明において、好ましくは、上記有機モリブデン化合物として、モリブデンジチオカーバメイト(MoDTC)を用い、上記脂環式エポキシ化合物として、エステル結合及び2個のエポキシ化シクロアルカンを有するものを用い、さらに上記潤滑油基油として、100℃における動粘度が4.5mm2/s以下のものを用いるものである。
鉱油、合成油又はこれらの混合油にしても、本発明の省燃費型エンジン油組成物に用いる場合、JIS K2283に規定する方法による100℃における動粘度が4.5mm2/s以下でかつ粘度指数が120以上のものが好ましいが、さらには、100℃における動粘度が1.0mm2/s以上、ASTM D2140に規定する方法のn‐d‐M環分析による%CPが80以上、JIS K2269に規定する方法による流動点が−10℃以下のものが、より好ましい。
有機モリブデン化合物として、具体的には、モリブデンジチオカーバメイト(MoDTC)、モリブデンジチオホスフェート(MoDTP)、Moアミンコンプレックスなどが挙げられる。この中で、MoDTCが最も好ましく、MoDTPはリンが排ガス浄化の三元触媒を被毒するため、あまり好ましくない。
本発明において、MoDTCとしては、下記一般式(1)で表されるものを好ましく使用できる。
この脂環式エポキシ化合物の含有量は有効量含有させればよく、エンジン油組成物全量基準で0.05〜2質量%の範囲で適宜選定すればよい。
アルカリ土類金属スルホネートとしては、分子量300〜1,500、特に好ましくは400〜700のアルキル芳香族スルホン酸のアルカリ土類金属塩、特にマグネシウム塩及び/又はカルシウム塩であり、カルシウム塩が好ましく用いられる。
アルカリ土類金属サリシレートとしては、炭素数1〜30、好ましくは6〜18の直鎖又は分枝のアルキル基を有するアルキルサリチル酸のアルカリ土類金属塩、特に好ましくは、マグネシウム塩及び/又はカルシウム塩が好ましく用いられる。
上記金属系清浄剤の含有量は任意であるが、省燃費型エンジン油組成物全質量に対して、金属量で0.05〜0.22質量%、好ましくは0.1〜0.2質量%含有させることが望ましい。
また、ポリブテニルコハク酸イミドの誘導体としては、上記ポリブテニルコハク酸イミドに、ホウ酸等のホウ素化合物や、アルコール、アルデヒド、ケトン、アルキルフェノール、環状カーボネート、有機酸等の含酸素有機化合物を作用させて、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又はアミド化した、いわゆる変性コハク酸イミドとして用いることができる。特に、ホウ酸等のホウ素化合物との反応で得られるホウ素含有アルケニル(もしくはアルキル)コハク酸イミドは、熱・酸化安定性の面で優れている。
この無灰分散剤の含有量は任意であるが、省燃費型エンジン油組成物全質量に対して、0.5〜15質量%含有することが好ましい。
ZnDTPとしては、炭素数1〜24の直鎖状又は分枝状のアルキル基、炭素数3〜24の直鎖状又は分枝状のアルケニル基又は直鎖状若しくは分枝状のアルキルシクロアルキル基、炭素数6〜18のアリール基又は直鎖状若しくは分枝状のアルキルアリール基を有する化合物が好ましい。なお、このアルキル基やアルケニル基は、第1級、第2級及び第3級のいずれであってもよい。
ZnDTPの含有量は、エンジン油全重量に対して、ZnDTPに含まれるリン(P)金属元素重量で0.01〜0.10質量%が好ましく、0.03〜0.08質量%がより好ましい。
基油としては、重質油の水素化分解で得られた生成油を水素化脱ロウすることで得られた鉱油系基油(動粘度:17.7mm2/s(40℃)、4.1mm2/s(100℃)、粘度指数:134、%CP:85、流動点:−20℃)を用いた。
ベンゾトリアゾール誘導体としては、N,N-ビス[(2‐エチルヘキシル)アミノメチル]‐1H‐ベンゾトリアゾール(チバスペシャリティ社製、Irgamet39)を使用した。
エポキシ化合物としては、脂環式エポキシ化合物である3,4‐エポキシシクロヘキシルメチル‐3,4‐エポキシシクロヘキサンカルボキシレートを、また比較のために、非脂環式エポキシ化合物である2‐エチルヘキシルグリシジルエーテル(エポキシ化合物1)及びネオデカン酸グリシジルエステル(エポキシ化合物2)を使用した。
粘度指数向上剤としては、ポリメタクリレート系化合物を用いた。
また、供試エンジン油の省燃費性をSRV摩擦試験(試験条件:荷重400N、振幅1.5mm、 振動数50Hz、温度100℃)で評価し、良好な場合を○とし、不良な場合を×とした。
これらの結果を表2に示す。
一方、MoDTCも脂環式エポキシも用いない比較例1では、腐食酸化安定性試験でのCuやPbの溶出は少ないものの、省燃費性が劣る。MoDTCを配合し、脂環式エポキシ化合物を配合しなかった比較例2では、省燃費性に優れるものの、腐食酸化安定性試験でのCuの著しい腐食が生じた。
また、MoDTCと共にベンゾトリアゾール誘導体を用いた比較例3、4ではベンゾトリアゾール誘導体の配合量が少ないとCuの溶出が多く、又はベンゾトリアゾール誘導体の配合量が多いとPbの溶出が多く、省燃費性に優れるものの腐食酸化安定性に劣ることが分かる。また、MoDTCと共に非脂環式エポキシ化合物を用いた比較例5、6ではCuの溶出が多く、特に脂肪酸とエポキシのエステルは、防食性が極めて低いことが分かる。
