This invention relates to compositions containing a sulfur containing antiwear/extreme pressure agent, basic nitrogen compound or a mixture thereof together with a hydrocarbyl mercaptan. The composition may additionally contain a phosphorus or boron antiwear or extreme pressure agent, a dispersant or an overbased metal salt. The invention also relates to lubricants, functional fluids, and concentrates containing the same. Seals, e.g. nitrile, polyacrylate, and fluoroelastomer, in contact with these composition have reduced deterioration. With the use of these compositions, lubricants, and functional fluids, the seals' useful life is extended.
本发明涉及含有含
硫抗磨剂/极压剂、碱性氮化合物或其混合物以及烃基
硫醇的组合物。此外,该组合物还可含有
磷或
硼抗磨剂或极压剂、分散剂或过基
金属盐。本发明还涉及润滑剂、功能性液体以及含有这些成分的浓缩物。与这些组合物接触的密封件(如
丁腈橡胶、聚
丙烯酸酯和
氟橡胶)可减少劣化。使用这些组合物、润滑剂和功能性液体可延长密封件的使用寿命。
