一种乙醇发动机润滑油组合物
摘要：
本发明涉及一种乙醇发动机润滑油组合物，包括下列组分：A)复合抗氧剂，至少包括以下组分：(1)烷基化二苯胺抗氧剂；(2)硫代酚酯型抗氧剂；(3)非必要的硫醚酚型抗氧剂；B)聚异丁烯丁二酰亚胺；C)磺酸钙和磺酸钠的混合物；D)二烷基二硫代磷酸锌；E)二烷基二硫代氨基甲酸酯；F)金属减活剂；G)主要量的润滑油基础油。本发明发挥添加剂之间的协同效应，能够满足乙醇发动机润滑油所要求的高温抗氧化性能，同时又能提供优异的活塞清净性、高低温抗磨性能和优异的控制粘度增长能力。
摘要（英）：

The invention discloses a lubricant composition for an ethanol engine. The lubricant composition comprises A) a composite antioxidant comprising at least components of 1, an alkylated diphenylamine antioxidant, 2, a thiophenolic ester antioxidant and 3, an unessential phenolic thioether antioxidant, B) polyisobutylene succinimide, C) a mixture of calcium sulfonate and sodium sulfonate, D) at least one zinc dialkyl dithiophosphate, E) one or more dialkyl dithiocarbamates, F) one or more metal deactivators, and G) a main amount of lubricating base oil. The lubricant composition has a synergistic effect of the additives, can satisfy high-temperature antioxidation requirements of lubricating oil for an ethanol engine, and has excellent piston cleanliness, high/low-temperature wear resistance and a good viscosity increasing control capacity.
