一种汽车液压制动系统润滑脂
技术领域
本发明涉及润滑油技术领域，特别涉及一种汽车液压制动系统润滑脂。
背景技术
润滑脂(lubricating grease)，稠厚的油脂状半固体。用于机械的摩擦部分，起润滑和密封作用。也用于金属表面，起填充空隙和防锈作用。润滑脂主要由矿物油和稠化剂调制而成。绝大多数润滑脂用于润滑，称为减摩润滑脂。减摩润滑脂主要起降低机械摩擦，防止机械磨损的作用。同时还兼起防止金属腐蚀的保护及密封防尘作用。润滑脂的工作原理是稠化剂将油保持在需要润滑的位置上，有负载时，稠化剂将油释放出来，从而起到润滑作用。
一般的汽车液压制动系统主要由制动踏板、真空助力泵、制动总泵、制动液、制动油管、ABS泵总成、制动分泵和车轮制动器组成，为确保制动系统的稳定运转，系统皮碗与金属间的润滑效果起着很大的影响。
针对市场需求，需要一种可具有优良的高低温性能、润滑性、胶体安定性、氧化安定性，与橡胶相容性良好，可适用于汽车液压制动系统皮碗与金属间的润滑的汽车液压制动系统润滑脂。
发明内容

本发明中一种汽车液压制动系统润滑脂，以该润滑脂总重量为基准，包含如下组分：82～90.6％的合成基础油、9～16％的皂基稠化剂、0.2～1.0％的抗氧剂及0.2～2.0％的金属减活剂。
进一步的，所述合成基础油为聚醚基础油与癸二酸二辛酯的混合物。
进一步的，所述的聚醚基础油可为环氧乙烷、环氧丙烷的均聚物，或任意比例环氧乙烷与环氧丙烷的共聚物中的一种或多种混合物。
进一步的，所述聚醚基础油在40℃运动粘度为100～260mm2/s。
进一步的，所述皂基稠化剂为硬脂酸锂皂、12-羟基硬脂酸锂皂中的一种或两种混合物。
进一步的，所述抗氧剂为二异辛基二苯胺、丁辛基二苯胺、N-苯基-α-萘胺、防老剂RD中的一种或多种混合物。
进一步的，所述金属减活剂为苯骈三氮唑、噻二唑衍生物中的一种或两种混合物。
