The invention is in the field of lubricating oils and the imparting of anti-corrosion properties thereto. Lubricating oil formulations, e.g. lubricating oil formulated for use in an engine crankcase, having improved anti-corrosion properties may be produced by the incorporation in the formulations of a minor amount of the combination of (a) a block-oxyalkylated trimethylol alkane containing an initial hydrophobic block of propyleneoxy and optionally random ethyleneoxy units and a terminal hydrophilic block of ethyleneoxy and optionally random propyleneoxy units and (b) an oxyethylated alkylphenol.
本发明涉及润滑油及其防腐性能领域。润滑油配方,例如用于发动机曲轴箱的润滑油配方,可通过在配方中加入少量以下物质的组合来生产具有更好防腐蚀性能的润滑油配方:(a) 嵌段烷氧基化的三羟甲基烷,该烷烃含有由丙烯氧基单元和可选的无规乙烯氧基单元组成的初始疏水嵌段,以及由乙烯氧基单元和可选的无规丙烯氧基单元组成的末端亲水嵌段;(b) 氧乙基化的烷基酚。
