背景技术
在适用于液压系统、循环油或其他工业流体的润滑组合物中使用诸如二烷基二硫代硫酸锌之类的含金属的抗磨剂是众所周知的。然而，二烷基二硫代磷酸锌在液压系统中会形成诸如树脂、油泥和漆膜之类的沉积物。这些沉积物会造成阀门粘着和控制失灵而影响液压系统的性能。此外，这些系统的清洁也是很困难的，因为没有机械摩擦，这些沉积物是很难除去的。
国际公开WO 96/035765披露了一种润滑组合物，其具有减少锈蚀或避免锈蚀的量的0.1-3wt％的合成芳基磺酸金属盐和0.01-2wt％的脂族琥珀酸或酸酐。此外，排除了使用取代的聚异丁烯琥珀酸或酸酐衍生物的多元醇酯或多胺，因为含所述添加剂的润滑组合物未显示出具有可接受的抗锈蚀特性。
美国专利4,419,251和4,419,252披露了具有水包油特性的水性润滑剂，其含有分散剂/乳化剂体系和抗磨/防锈包。
美国专利5,262,073披露了一种润滑组合物，其含有锌分散剂、0.3-1wt％的合成壬基联萘磺酸钙清净剂和0.09-0.85wt％的烷基酚钙。
美国专利6,677,281披露了一种润滑组合物，其含有金属磺酸盐、无灰烯基琥珀酰亚胺和硼酸化聚烯烃分散剂。
美国专利4,466,894披露了一种组合物，其含有金属的磷硫醇盐、硫化酚盐和苯并三唑。
国际公开WO 93/03121披露了与脂族羧酸或其酸酐组合的至少一种磺酸盐、羧酸盐和酚盐的金属盐。
对于润滑组合物来说，期望其提供可接受的抗磨性能，同时降低或避免形成沉积物。本发明提供了一种润滑组合物，其具有可接受的抗磨性能，同时降低或避免形成沉积物。

本文使用的术语“基本不含”是指润滑组合物含有不超过污染量的水，如水占润滑组合物的量小于约2wt％，优选小于约1wt％，或甚至约0.5wt％或更少。
然而，应注意，在润滑组合物用于工业流体、液压液、汽轮机油、循环油或其组合期间，可向系统中加入外来水。外来水并不包括在上述污染量的水中。
在一种实施方案中，润滑组合物基本不含水，至不存在水。在一种实施方案中，润滑组合物不是水包油乳液。

实施例
按下表所示制备润滑组合物(实施例A至C)。
＊添加剂包括清净剂、抗氧化剂、破乳剂、消泡剂、缓蚀剂、和聚异丁烯琥珀酸酐中的一种或多种。
对实施例A至C进行了一系列的测试，以测定润滑组合物对液压系统的有效性。
测试1是依据M-2950-S进行的Modified Eaton Vickers 35VQ25泵测试，但测试时间是1000小时。测试结束时，油箱或系统其它部件中没有发现漆膜。
测试2是根据Parker Hannifin A-TP-30533进行的T6H20C混合泵测试。
测试3测定了润滑组合物产生降低量的油泥的性能。测试采用Cincinnati Lamb Landis程序‘A’热稳定性测试。生成油泥的量约是1.8mg。对于当前流体技术，这种油泥水平被视为非常低的。
测试4是DIN 51 354 FZG擦伤测试。实施例A至C在载荷级12失败。
测试5和测试6分别测试了实施例A至C的水解稳定性(依据ASTMD2619)和破乳化能力(依据ASTM D1401)。所得结果表明实施例水解稳定，且破乳化性能好。
测试7依据ASTM D943汽轮机油稳定性测试评价使用寿命。所得实施例A至C的结果比市场上可以购得的含二烷基二硫代磷酸锌的对比例相比得以改进。市场上可购得产品的寿命约为2000小时，而本发明润滑组合物的寿命超过了3500小时。
数据表明，本发明润滑组合物使工业流体、液压液、汽轮机油、循环油或其组合具有降低的或得以避免的树脂形成、油泥形成和漆膜形成中的至少一种性能。润滑组合物也提供了可接受的抗磨性和清洁性中的至少一种。
本说明书中，本文使用的术语“烃基取代基”或“烃基”，以本领域技术人员所熟知的一般含义使用。特别地，其是指主要由碳和氢原子组成，并通过碳原子结合于分子的其余部分的基团，并不排除其它原子或基团以不足以影响分子具有的主要的烃特性的量存在。通常，在烃基中，每10个碳原子存在的非烃取代基不超过2个，优选不超过1个；典型地，烃基中没有非烃取代基。术语“烃基取代基”或“烃基”更详细的定义描述在美国专利6,583,092中。
已结合优选实施方案对本发明进行了说明，通过阅读本说明书，各种改进对本领域技术人员而言是显而易见的。因此，可以理解在此公开的发明覆盖落在所附权利要求范围之内的所有改进。
