This invention relates to lubricant compositions containing both zinc O,O′-dialkyldithiophosphates and ashless O,O′-diaryldithiophosphates obtained by reacting an O,O′-diaryldithiophosphoric acid with a diolefin. These lubricant compositions give improved anti-wear performance.
本发明涉及含有 O,O′-二烷基二硫代磷酸锌和通过 O,O′-二烷基二硫代磷酸与二烯烃反应获得的无灰分 O,O′-二烷基二硫代磷酸的润滑剂组合物。这些润滑剂组合物具有更好的抗磨损性能。
