Abstract
Description
本発明は、エンジン潤滑剤、ならびに内燃エンジンのクランク室の潤滑剤および運搬用車両でのその他の潤滑用途における燃費の向上を目的とした特定の官能基化ポリマーの使用に関する。
したがって、本発明は、内燃エンジンを潤滑するのに適した組成物であって、(a)潤滑粘度(lubricating viscosity)の油;(b)アミノ官能基化されたアクリル含有またはメタクリル含有ポリマーであって、エステル結合、アミド結合、もしくはイミド結合またはこのような結合の組み合わせを介して該ポリマーに結合した、2重量パーセント〜8重量パーセントの三級アミノ基含有アミン部分を含む、ポリマー;および(c)分散剤を含む、組成物を提供する。
種々の好ましい特徴および実施形態を、以下の非限定的な例によって説明する。
(HR1 aX)a−R2−(NR3R4)b
ここで、R2はa+b価のヒドロカルビル基であり、一般的には1〜8個の炭素原子を含み(例えば、エチレン基、プロピレン基、またはブチレン基);aは少なくとも1であり、一般的には1であり;bは少なくとも1(1または2など)であり、一般的には1であり;XはOまたはNである。XがOである場合、nは0であり、XがNである場合、nは1である。R1は水素あるいはヒドロカルビル基(メチルまたはエチルなどの短いアルキル基)である。R3およびR4はそれぞれ独立して、1〜8個の炭素原子の低級アルキル基(メチル基、エチル基、またはプロピル基など)などのヒドロカルビル基である。特定の実施形態において、R3およびR4はそれぞれメチル基である。特定の実施形態において、R1はHであり、R2はエチレンまたはプロピレンであり、R3およびR4はそれぞれメチルである。
[(R8O)(R9O)P(=S)−S]n−M
ここで、R8およびR9は独立して3〜30個の炭素原子を含むヒドロカルビル基である)。反応してR8およびR9基をもたらすアルコールは、アルコールの混合物、例えば、イソプロパノールと4−メチル−2−ペンタノールの混合物であってよく、実施形態によっては、二級アルコールと一級アルコール(イソプロパノールと2−エチルヘキサノールなど)の混合物であってよい。得られた酸は、塩基性金属化合物と反応して塩を形成し得る。原子価nの金属Mは一般的に、アルミニウム、鉛、スズ、マンガン、コバルト、ニッケル、亜鉛、または銅であり、多くの場合、ジアルキルジチオリン酸亜鉛を形成する亜鉛である。このような物質はよく知られており、潤滑剤配合物を当業者が容易に入手できるものである。
炭化水素置換基、すなわち、脂肪族(例えば、アルキルまたはアルケニル)置換基、脂環式(例えば、シクロアルキル、シクロアルケニル)置換基、および芳香族置換、脂肪族置換、および脂環式置換の芳香族置換基、ならびに環状置換基(ここで、環は分子の別の部分を介して完成している(例えば、2個の置換基が一緒になって環を形成する));
置換炭化水素置換基、すなわち、本発明との関連では、置換基の主な炭化水素性(hydrocarbon nature)を変えない非炭化水素基(例えば、ハロ(特にクロロおよびフルオロ)、ヒドロキシ、アルコキシ、メルカプト、アルキルメルカプト、ニトロ、ニトロソ、およびスルホキシ)を含む置換基;
ヘテロ置換基、すなわち、主として炭化水素の性質を有するが、本発明との関連では、(普通は炭素原子でできている)環または鎖の中に炭素以外のものを含む置換基。ヘテロ原子としては、硫黄、酸素、窒素があり、ヘテロ原子はピリジル、フリル、チエニルおよびイミダゾリルのような置換基を包含する。一般的に、2個以下、好ましくは1個以下の非炭化水素置換基が、ヒドロカルビル基中の炭素原子10個ごとに存在し、一般的には、ヒドロカルビル基中に非炭化水素置換基はない。
第A部 マレイン酸無水物含有PMA: 3.8L(1ガロン)のガラスジャーに、メタクリル酸2−エチルヘキシル239.6g、メタクリル酸ラウリル544.8g、TotalTM 85N油342g、Trigonox−21TM開始剤0.4gおよびn−ドデシルメルカプタン0.4gを仕込み、30分間攪拌する。オーバーヘッド撹拌機、還流冷却器、温度計、および水中窒素ガス送込管を取り付けた3Lの四つ口フラスコに、上記の混合物のおよそ1/3を仕込み、35℃まで加熱し、その温度で、アセトン80gに溶かしたマレイン酸無水物28.76gもさらに仕込む。その混合物を攪拌しながら110℃まで加熱し、その時点で形成時発熱化合物が生じ、それによって温度は116℃になる。その形成時発熱化合物が最大量に達したなら、モノマー混合物の残りの2/3を90分間かけて添加する。その間に温度は110℃に下がり、その温度に保持される。この添加の後、反応フラスコにディーン・スターク・トラップを取り付けて、アセトンおよび他の揮発分を回収する。次いで反応器にTrigonox−21TM開始剤0.6gを仕込み、さらに1時間110℃に保持する。そのときに、TotalTM 85N油の残りの858gを加える。次いで反応混合物を130℃および2.7kPa(20mmHg)で1時間かけてストリッピングしてから、Fax−5TM濾過助剤50gを利用し、布パッドを通過させて濾過する。
潤滑剤配合物は、以下の表に示すようにして製造する。
実施例2の配合物と似た配合物を製造するが、但し、これは実施例1におけるようにして製造したポリマー(しかし、マレイン酸無水物モノマーおよびDMAPAを約2分の1の量しか含まないもの)を含む。したがって、これは約1.8%のDMAPAしか含まないものになる。上記の試験における摩擦性能は、実施例2ほど良好ではない。
3.8L(1ガロン)のガラスジャーに、メタクリル酸2−エチルヘキシル574.0g、C12〜15のアルキルメタクリレート1674.5g、希釈油1602g、Trigonox−21TM開始剤1.62gおよびn−ドデシルメルカプタン1.62gを仕込み、30分間攪拌する。オーバーヘッド撹拌機、還流冷却器、温度計、および水中窒素ガス送込管を取り付けた12Lの四つ口フラスコに、上記の混合物のおよそ1/3を仕込み、35℃まで加熱し、その温度で、N,N−ジメチルアミノプロピルメタクリルアミド143.5gもさらに仕込む。その混合物を攪拌しながら、17L/時間(0.6ft3/時間)の窒素流のもとで110℃まで加熱すると、そのときに形成時発熱化合物が生じて温度が126℃になる。形成時発熱化合物が最大量に達したら、モノマー混合物の残りの2/3を90分間かけて110℃にて添加する。この添加の後、14L/時間(0.5ft3/時間)の窒素流のもとで1時間にわたり110℃にて攪拌を続ける。追加分のTrigonox−21TM開始剤1.2gを加え、110℃にて1時間攪拌を続ける。Trigonox−21TMの追加および攪拌をさらに3回繰り返し、それぞれ1.2gを合計で4回段階的に追加して増量する。内容物を1時間の間、攪拌しながら28L/時間(1ft3/時間)の窒素流のもとで130℃まで加熱し、その後、混合物を130℃および2.7kPaの圧力(20mmHg)で真空ストリッピングする。希釈油1990gもさらに加え、得られた混合物を100℃にてFax−5TM濾過助剤50gを利用して布パッドを通過させて濾過し、所望の分散剤ポリマーを得る。場合により、希釈油1331gを追加でさらに加えてもよい。
