Abstract
Description
の基油;並びに、添加剤パッケージ、消泡剤及び粘度調整剤を更に含む流体を含むトラクション流体を提供する。
式I、II、III、IV、V、VI、VII又は式I、II、III、IV、V、VI及びVIIの組合せは、最終的な完全配合されたトラクション流体のための基油又はベースストックに対する補足剤として役立ち得る。トラクション流体は、他のベースストックと、式I、II、III IV、V、VI及びVIIとの様々な比での組合せをも含み得る。
トラクション流体は、粘度調整剤又は粘度調整剤の組合せを含んでいてもよい。潤滑剤産業において使用される粘度向上剤は、本発明において油剤媒体として使用することができ、油剤媒体には、オレフィンコポリマー(OCP)、ポリメタクリラート(PMA)、水素化スチレンジエン(STD)及びスチレンポリエステル(STPE)ポリマーが含まれる。オレフィンコポリマーは、エチレン及びプロピレンの混合物からバナジウム系のZiegler-Natta触媒によって調製されたゴム状物質である。スチレンジエンポリマーは、スチレン、ブタジエン又はイソプレンの陰イオン重合によって製造される。ポリメタクリラートは、アルキルメタクリラートのフリーラジカル重合によって製造される。スチレンポリエステルポリマーは、まずスチレン及び無水マレイン酸を共重合し、次いで、アルコールの混合物を使用して中間体をエステル化することによって調製される。
添加剤パッケージ中に存在し得る任意の脱泡剤又は消泡剤に加えて、少なくとも1種の更なる消泡剤がトラクション流体に添加されてもよい。好ましくは、少なくとも2種の消泡剤がトラクション流体に添加される。2種を超える消泡剤もトラクション流体に添加されてもよい。トラクション流体は、有機酸エステル、シロキサン、シリコーン系流体又はこれらの化合物の任意の組合せである消泡剤を含んでもよい。1つの消泡剤は、有機酸エステル及びシロキサン等の化合物の混合物、例えば、市販されているNalco 2301等を含んでもよい。1つの消泡剤は、例えば市販されているChemaloy F-655等のシリコーン系であってもよい。
トラクション流体は、少なくとも1種の性能添加剤パッケージを含んでもよい。性能添加剤パッケージは、一般に、酸化防止剤、抗摩耗剤、極圧剤、洗剤、分散剤、消泡剤、抗さび剤、摩擦調整剤、腐食防止剤及び流動点降下剤を含む、完全配合された組成物である。性能添加剤パッケージは、DIパッケージ等として市販され、製造業者によって指示される通りに使用することができる。色素又は染料等の添加剤を、トラクション流体に添加してもよい。
を有する化合物を含んでいてよい。
式II及び式VIの一般構造は、以下のように要約することができる:
ここで図1Aを参照すると、純粋なトラクション流体及び配合したトラクション流体を用いた実験データが示される。データは、図1Bにグラフにより表される。純粋な材料として、式II及びVIは、ブレンド-1(参照流体)と比較して、Brookfield粘度(BF)において-30℃でそれぞれ78.24%及び90.57%の改善を、それぞれ7.96%及び5.2%のトラクション損失とともに示す。10質量%の式IIを含む図1Aのブレンド2等のブレンドは、トラクション係数をほとんど同じに保ちつつ、17.94%のBF粘度改善を示した。式IIを45.4%含むブレンド3は、50.38%のBF粘度改善を、5.94%のトラクション損失とともに有していた。式VIを20%含むブレンド8は、35.3%のBF粘度改善を有し、トラクション損失は1.48%のみであった。(参照:図1A)。
