Description

用于液压流体和润滑组合物的磷酸酯基添加剂
本发明涉及改进的液压流休和润滑组合物。更具休地说，本发明提供了使液压流体和齿轮润滑组合物具有改进性能的新的添加剂组合物。
液压流体是用来在各种各样的工业机器中传递力和运动。它们在液压系统中使用，在液压系统中流体是在压力下，并与运动零件接触。这些运动零件通常有精密的配合公差，各种冶金学和在高容积高效率及高压下操作。液压流体特别要求的特征是优良的耐氧化、磨损、抗锈蚀和腐蚀。由不适宜的氧化抑制而产生的液压流体的变质将对液压油和其有效地传递功率及润滑液压系统的能力都有不利的影响。
如果油被水污染，那么液压油的过滤性也会受到不利的影响。与水接触的液压油的差过滤性将阻止液压系统将力传递给液压马达。
液压油也必须具有与水分离的能力。虽然少量的水可以允许，但是大量的水会产生锈蚀、氧化，降低润滑能力和使泵的作用不稳定。
由于液压油的多功能特性，工业上可接受的液压流体组合物必须满足用于所有临界特征所建立的工业标准。
特别有用的是抗磨液压油，它具有润滑油的磨损特性和许多工作特性。过去，抗磨液压油是用锌化合物例如二硫代磷酸盐等配制的。
除锌化合物外，抗磨液压油还含有必须防止设备磨损和变坏，同时该油还可传递所要求的功率和运动的补充的其它添加剂。使用锌基抗磨添加剂的润滑组事物含有需适于特殊用途的润滑功能的其它的功能添加剂。因此，现有技术介绍了两种不同锌基组合物，一种是指定专门用作液压流体，另一种是指定专门用作润滑剂。
美国专利4383931号介绍了含硫化油和亚甲基双(二烃基二硫代氨基甲酸酯)和二烃基二硫代磷酸锌一起组合的润滑组合物。
美国专利3876550号公开了以亚甲基双(二烃基二硫代氨基甲酸酯)和琥珀酸型的锈蚀抑制剂一起为基础的相似的多功能组合物。美国专利3359203号介绍了应用二烃基二硫代磷酸和马来酸或富马酸的脂族酯和酚型抗氧化剂一起的加合物。
美国专利4880551号公开了含1-[二(4-辛基苯基)氨基甲基]甲苯三唑、亚甲基双(二-正丁基二硫代氨基甲酸酯)和酚抗氧化剂组成的抗氧化剂协合剂的润滑组合物。
美国专利4130494号介绍了通过添加磷酸酯的有机胺盐和有机磺酸铵盐的组合物来提高合成润滑剂的载荷能力。
美国专利4225450号公开了用二硫代氨基甲酸羟苄酯和其它的润滑抗氧化剂例如芳族胺、位阻酚、硫代二丙酸酯、二硫代磷酸盐、腐蚀抑制剂例如苯并三唑、有机胺、磷酸部分酯的胺盐、二壬基萘基磺酸盐等稳定的润滑剂。
上述参考文献的润滑组合物中没有一种具有液压功能。
美国专利3658706号公开了由硫代磷酸酯和二烃基硫代链烷酸酯组成的用于润滑和功能流体的抗氧化剂。
液压油含金属腐蚀抑制剂和锈蚀抑制剂。美国专利2971912号公开了苯并三唑型金属腐蚀抑制剂。已知把磺酸盐型锈蚀抑制剂加到含锌的液压油，就像美国专利3843542号、3923669号和3791976号所描述的那样。
由于重金属锌的毒性而影响环境问题，所以有人提出了含锌的液压油是不符合要求的。不利的是，目前可得到的不含或含少量锌的抗磨液压油已禁止工业应用。这些所谓无灰抗磨液压油不能够满足所有测试标准，也就是说，它们不具有抗磨液压油所要求的变化和补偿性能。
令人意外的是，已经发现某些磷酸酯和磺酸酯与其它功能添加剂一起的协合组合物，这些组合物向液压油提供了所需的补偿的标准性能，即使在没有锌的存在下，这些组合物也能使液压油完成所需的液压功能。
按照本发明，提供了用于基础油的协合抗氧化剂组合物，该组合物含有(1)烷基磷酸的胺盐，其中胺选自氨、伯和仲烷基胺，和(2)石油或芳族磺酸的乙二胺、铵或金属盐，其中金属选自碱或碱土金属，芳族取代基选自具有1-4个烷基、每个烷基有8-20个碳原子的烷基化苯和烷基化萘，并且其中磷酸盐与磺酸盐用量的临界比为约14∶1-1∶2.75。
本发明的一个目的是提供润滑组合物，所述的润滑组合物包括主要量的和抑制氧化量的上述协合抗氧化剂组合物。
本发明的另一个目的是提供液压油组合物，所述的液压油组合物包括：
(a)主要量的基础油；
(b)抑制氧化量的协合抗氧化剂组合物，所述协合抗氧化组合物由下列组分组成：(1)烷基磷酸的胺盐，其中胺选自氨、伯和仲烷基胺，和(2)石油或芳族磺酸的乙二胺、铵或金属盐，其中金属选自碱或碱土金属，芳族取代基选自具有1-4个烷基、且每个烷基有8-20个碳原子的烷基化苯和烷基化萘，其中磷酸盐与磺酸盐是以临界比存在；

结构式为(i)的二烷基二硫代磷酸琥珀酸酯，其中R和R1独立地选自3-8个碳原子的烷基，
结构式为(ii)的羧酸的二硫代磷酸酯，
Figure A9810010000072
其中R2是3-8个碳原子的烷基，R3是2-8个碳原子的烷基，和
结构式为(iii)的三苯基硫代磷酸酯，
Figure A9810010000081
其中n＝1-2，m＝2-3，R3是1-20个碳原子的烷基，R4和R5是H或烷基；
(d)亚甲基双(二烷基二硫代氨基甲酸酯)，其中烷基含4-8个碳原子；
(e)金属钝化量的组合物，其选自：
(i)三唑化合物，其选自1-(苯基氨基甲基)甲苯三唑和1-(苯基氨基甲基)苯并三唑，其中苯基可有1-3个取代基，所述取代基选自烷基或芳烷基和它们的混合物，
(ii)由苯并三唑和二苯胺组成的组合物，其中二苯胺被1-3个烷基或芳烷基或它们的混合物取代，且其中苯并三唑与二苯胺的摩尔比为1∶1，和
(iii)由甲苯三唑和二苯胺组成的组合物，其中二苯胺被1-3个烷基或芳烷基或它们的混合物取代，且其中甲苯三唑与二苯胺的摩尔比为1∶1；
(f)位阻酚抗氧化剂，其选自具有至少两个烷基取代基，且每个取代基有1-4个碳原子的烷基化酚；和任选的
(g)酸式磷酸烷基酯、烷基芳基磺酸或它们的混合物。
本发明的稳定组合物是由协合地用作抗氧化剂的市售组分与在抗磨液压油和齿轮润滑油中产生所要求特性的其它功能添加剂组成。
烷基磷酸的协合胺盐是由已知的方法制备，例如美国专利4130494号中所述的方法制备。适宜的磷酸单或二酯或它们的混合物用胺中和。当使用单酯时，将需2摩尔的胺，而使用二酯时，将要求1摩尔的胺。总之，所需要的胺量可以通过监测总酸值基本上等于总碱值的反应的中和点来控制。另外，氨或乙二胺之类的中和剂可以加到反应中。
优选的磷酸酯是脂族酯，尤其是2-乙基己基、正辛基和己基单或二酯。胺类可选自伯胺或仲胺。特别优选的是10-24个碳原子的叔烷基胺。这些胺是市售的，例如由罗姆和哈斯公司制造的Primene81R。
协合磺酸盐是本领域已知的，并且是市售的。可以用于制备本发明协合剂的芳族磺酸的代表是有1-4个烷基的、每个烷基有8-20个碳原子的烷基化苯磺酸和烷基化萘磺酸。特别优9-18个碳原子(每个烷基)的烷基取代的萘磺酸盐，例如二壬基萘磺酸盐。
磺酸盐以氨、乙二胺、碱金属或碱土金属的中性盐的形式使用。特别优选的是碱式钙盐和碱式锂盐。碱式盐是与酸有关的金属氩氧化物分子的形式。
协合组合物用作抗氧化剂，减少了基础油变质，氧化产物的生成，如渣和金属零件上的沉积物。因此，油润滑和保护完整的液压系统的能力不能得到兼顾。
协合抗磨组合物特别适宜于二硫代磷酸酯型无灰分抗磨剂。一类化合物是O，O-二烷基二硫代磷酸酯和马来酸或富马酸的酯的加合物。该化合物可以通过美国专利3359203号描述的已知方法制备，例如O，O-二(2-乙基己基)S-(1，2-二羰基丁氧基乙基)二硫代磷酸酯。
用于本发明的另一类化合物是羧酸酯的二硫化磷酸酯。优选2-8个碳原子的烷基酯，例如3-{[双(1-甲基乙氧基)硫膦基]硫代}丙酸乙酯。本发明的第三类无灰二硫代磷酸酯是三苯基硫代磷酸酯，其中苯基可以被多达两个烷基取代。尤其是，这类的一个实例是可市售的三苯基-硫代磷酸酯，商品名为IRGALUBETPPT(由Ciba-Geigy制造)。
亚甲基双(二烷基二硫代氨基甲酸酯)化合物是市售的。例如，亚甲基双(二丁基二硫代氨基甲酸酯)是由R.T.Vanderbilt Company，Inc.制造，商品名为VANLUBE7723。
通过添加剂1-[二(4-辛基苯基)氨基甲基]甲基三唑和位阻酚化合物进一步提高液压油的抗氧化性和金属钝化作用，它们都如美国专利4880551号所述。
位阻酚可选自2，6-烷基取代的酚，可带多达四个烷基。特别优选的是2，6-二叔丁基酚、2，6-二-叔丁基-4-仲丁基酚、2，6-二-叔丁基-4-甲基酚和丁基化的酚的混合物。
令人惊奇的是，通过将酸或磷酸烷基酯和芳族磺酸或其混合物加到油组合物中可以提高油的过滤性。酸式磷酸烷基酯可以是酸式磷酸的二或单烷基酯，或其混合物。在可以是直链或支链，含6-12个碳原子。芳族磺酸可以选自烷基化的芳基磺酸。特别优选的是被1-4个烷基(每个烷基有8-20个碳原子)取代的苯磺酸和萘磺酸。
根据特殊的应用和所采用的设备，油组合物可包含已知的腐蚀抑制剂、锈蚀抑制剂和金属钝化剂。例如，腐蚀抑制剂例如甲苯三唑和2-烷基-1H-咪唑-1-乙醇，其中含7-17个碳原子的烷基是适合于液压流体的添加剂。
液压流体的基础油可以选自石油润滑油和矿物油的基础油原料。高粘度的高级矿物油对在许多液压体系中的应用是特别适合的液压流体。
齿轮润滑油的基础油可以是润滑粘度的矿物油或石油润滑油的基础油原料，例如环石蜡原料油和石蜡原料油。润滑油也可以由合成物质配制，例如以有机酯、聚乙二醇和烯烃低聚物为基础配制。润滑油组合物可以含粘度指数改进剂和分散剂。
向液压油提供所需的性能特性所要求的协合组合物的量可以是总油配方重量的约0.01-5％。优选的范围是总油配方重量的约0.05-0.20％。虽然协合组合物的单个组分是本领域内已知的，但是，必须以较高量添加添加剂。令人惊奇地发现，通过添加较低量的协合组合物满足了抗磨液压油的工业标准。这种实事表明，由于协合组合物与成品液压油配方的其它组分的适合的相互反应，提高了功能活性。润滑组合物可以含约0.1-10％的协合组合物，这取决于润滑剂的应用。
给出的下述实施例是用于进一步说明本发明，除非另有说明，所有的百分数和份数均以重量计。
