必要に応じて、本発明の組成物中に他の抗酸化剤を用いてもよい。典型的な抗酸化剤は、ヒンダードフェノール抗酸化剤、硫化フェノール抗酸化剤、油可溶性の銅化合物、リン含有の抗酸化剤、有機硫化物、二硫化物および多硫化物、ならびにメチレンビス(ジブチルジチオカルバミン酸)などのジアルキルジチオカルバミン酸化合物、およびジアルキルジチオカルバミン酸銅、ジアルキルジチオカルバミン酸亜鉛、ジアルキルジチオカルバミン酸ビスマスおよびジアルキルジチオカルバミン酸アンチモンなどの金属錯体が挙げられる。
摩擦調整剤は、当業者にも周知である。摩擦調整剤の有用なリストが、参照により本明細書に取り込まれる米国特許第4792410号に含まれている。米国特許第5110488号は、脂肪酸の金属塩、特に亜鉛塩を開示しており、参照により本明細書に取り込まれる。有用な摩擦調整剤としては、脂肪性ホスファイト、脂肪酸アミド、脂肪性のエポキシド、ホウ酸化した脂肪性のエポキサイド、脂肪性アミン、脂肪酸の金属塩、硫化オレフィン、脂肪性イミゾリン、モリブデンジチオカルバメート(例えば、参照により本明細書に取り込まれる米国特許第4259254号)、モリブデン酸エステル(例えば、いずれも参照により本明細書に取り込まれる米国特許第5137647号および米国特許第4889647号)、硫黄供与体を有するモリブデン酸アミン(例えば、参照により本明細書に取り込まれる米国特許第4164473号)、およびその混合物が挙げられる。
潤滑組成物はまた、硫黄を含有する類似体を含めた、少なくとも1種のリン酸、リン酸塩、リン酸エステルまたはその誘導体を、好ましくは0.002〜1.0重量%の量で含むことが好ましい。リン酸、リン酸塩、リン酸エステルまたはその誘導体は、リン酸エステルまたはその塩、ホスファイト、リン含有アミド、リン含有カルボン酸またはカルボン酸エステル、リン含有エーテルおよびその混合物から選択される化合物を含む。
粘度調整剤および分散粘度調整剤は、周知である。粘度調整剤および分散粘度調整剤の例は、ポリメタクリル酸、ポリアクリレート、ポリオレフィン、スチレン−マレイン酸エステルコポリマー、およびホモポリマー、コポリマーおよびグラフト共重合体を含めた類似の重合体材料である。以下は、市販の粘度調整剤、分散粘度調整剤およびそれらのケミカルタイプの例の一覧である。分散粘度調整剤は、その数の後に(D)と明記してある。代表的な市販の粘度調整剤は、以下の表1に挙げている。
このような成分は、潤滑油の低温特性を改善するのに特に有用である。好ましい流動点降下剤は、アルキルナフタレンである。流動点降下剤は、参照により本明細書に取り込まれる米国特許第4880553号および米国特許第4753745号で開示されている。流動点降下剤は一般に、低温および低剪断速度で測定する粘度を低下させるために潤滑組成物に通用される。流動点降下剤は、0.1〜5重量%の範囲で用いるのが好ましい。潤滑液の低温、低剪断速度での流動性を入手するために使用される試験の例としては、ASTM D97(流動点)、ASTM D2983(Brookfield粘度)、D4684(Mini−rotary粘度計)、およびD5133(Scanning Brookfield)が挙げられる。
多くの場合、潤滑組成物は、清浄剤も含むことが好ましい。清浄剤は、本明細書で使用する場合、有機酸の金属塩を含むことが好ましい。清浄剤の有機酸の部分は、スルホン酸、カルボン酸、石炭酸、またはサリチル酸が好ましい。清浄剤の金属部分は、アルカリまたはアルカリ土類金属が好ましい。好ましい金属は、ナトリウム、カルシウム、カリウム、およびマグネシウムである。清浄剤は、過塩基性であるのが好ましく、中性金属塩を形成するのに必要な量を超えて化学量論的に過剰な金属が存在することを意味する。
消泡剤は、当分野でケイ素樹脂組成物またはフルオロケイ素樹脂組成物として周知である。そのような消泡剤は、Dow Corning Chemical CorporationおよびUnion Carbide Corporationから入手可能である。好ましいフルオロケイ素樹脂消泡剤製品は、Dow FS−1265である。好ましいケイ素樹脂消泡剤製品は、Dow Corning DC−200およびUnion Carbide UC−L45である。該組成物に単独または混合のいずれかで含み得る他の消泡剤は、PC−1244として知られている、Nitro、West VirginiaのMonsanto Polymer Products Co.から入手可能なポリアクリレート消泡剤である。Farmington Hills, MichiganのOSI Specialities, Incから入手可能なシロキサンポリエーテルコポリマー消泡剤もまた挙げられる。そのような一物質は、SILWET−L−7220として販売されている。消泡剤製品は、好ましくは本発明の組成物に、油を含まない基準の活性成分として5〜80P.P.M.の濃度で含まれる。
錆阻害剤の実施形態は、アルキルナフタレンスルホン酸の金属塩を含む。任意選択で加えてもよい銅腐蝕阻害剤の実施形態には、チアゾール、トリアゾール、およびチアジアゾールが挙げられる。そのような化合物の実施形態の例として、ベンゾトリアゾール、トリルトリアゾール、オクチルトリアゾール、デシルトリアゾール、ドデシルトリアゾール、2−メルカプトベンゾチアゾール、2,5−ジナルカプト−1,3,4−チアジアゾール、2−メルカプト−5−ヒドロカルビルチオ−1,3,4−チアジアゾール、2−メルカプト−5−ヒドロカルビルジチオ−1,3,4−チアジアゾール、2,5−ビス(ヒドロカルビルチオ)−1,3,4−チアジアゾール、および2,5−ビス(ヒドロカルビルジチオ)−1,3,4−チアジアゾールが挙げられる。
酸化安定度は、ASTM D 6186で記載されているように、加圧した示差走査熱量測定法(PDSC)により測定した。PDSCは、潤滑組成物の抗酸化能力が劣化し、基油が自動酸化として知られる酸化的な連鎖反応へと進むときの発熱性の放熱を検出することによって酸化安定度を測定する。実験開始から自動酸化への時間は、酸化誘導時間(OIT)として知られている。したがって、OITが長いほど、酸化的安定度および抗酸化剤能力が大きいことを示している。
以下の実施例は、表Aに記載のデータと共に、ADPA、C6〜18モノグリセリドおよびエトキシ化アミド混合物、ならびに脱ろうした、重パラフィン系石油留分の35〜50質量%溶媒中に溶解したポリエチレンアミンおよびポリイソブチレン無水コハク酸由来のモノスクシンイミド分散剤の間に存在する抗酸化剤の相乗作用を示す。1モルのやし油と約2.0モルのジエタノールアミンを反応させることによって調製した、C6〜18モノグリセリドおよびエトキシ化アミド混合物である。
以下の実施例は、表Bに記載のデータと共に、ZDDPの形態のリンの存在下、ADPA、モノスクシンイミド分散剤、およびモノグリセリド、エトキシ化アミド、またはその混合物の間に存在する抗酸化剤相乗作用を示す。データは、グリセロールカルボン酸塩、エトキシ化アミドおよびその混合物が、リン濃度が減少したときに失った抗酸化剤能力を回復するのに有用であることを示している。
以下の実施例は、表Cに記載のデータと共に、リン(ZDDPとして)の存在下で、ADPA、ポリアミン分散剤およびホウ酸化モノグリセリド/エトキシ化アミド混合物の間に存在する抗酸化剤相乗作用を示す。データは、グリセロールカルボン酸塩/エトキシ化アミド混合物が、リン濃度が減少したときに失った抗酸化剤能力を回復するのに有用であることを示すとともに、リンが排除された場合でも、満足な抗酸化剤能力を達成することを実証している。加えてデータは、分散剤を欠いたシステムと比較した(比較試験18v.試験17)場合の、3成分システムに特有の相乗作用を実証するのに役立つ。リンなしにもかかわらず、3成分システムは、81.1でのPDSC OIT結果値を示し、これは、最小許容値である約55よりも上である。
自動車エンジンオイルの堆積物形成傾向を測定するために行った試験は、TEOST MHT4(高温酸化エンジンオイルシミュレーション試験 Thermo−oxidation Engine Oil Simulation Test Moderately High Temperature)である。この試験においては、酸化触媒で処置したエンジンオイルを、事前に秤量したワイヤーを巻いたロッドの外側に持続性に循環させるが、ロッドはガラスマントル内に入っている。ロッドを抵抗的に加熱することにより、最大温度285℃を得て、油を24時間循環し、乾燥し空気をケース内のガラスマントル内を10mL/分の速度で流動させる。24時間後に、ロッドを溶媒ですすぎ、残留油を取り出し、次いで乾燥させる。ロッド上の堆積物の質量と、すすいでいる間にロッドから取れたあらゆる堆積物とを加えたものを秤量し、試験前のロッドの重量と比較する。エンジンオイルに対するILSAC GF−4規格によると、全堆積物が35mg以下でなければならない。
3つの完全に配合した5W−20エンジンオイルをPDSCおよびTEOST MHT4で検査した。エンジンオイルAは、ポリアミン分散剤をエンジンオイルに典型的に使用される濃度で、ADPAを0.5質量%で、およびZDDPを油と共にリン0.1質量%となるような量で含む。エンジンオイルBはエンジンAと同じだが、より少ない量のZDDP、つまり油のみでリンが0.05質量%となる量を含む。エンジンオイルCは、エンジンオイルBと同じだが、エンジンオイルCは、1.0質量%のVanlube 289、ホウ酸化モノグリセリド/エトキシ化アミド混合物を含む。表Dの結果は、本発明の成分が、抗酸化性および堆積物制御の特性の両方において優れている、モリブデンを含まない、低リンのエンジンオイル(P<0.08質量%)を配合するのに有用であることを証明している。
