Description
技术领域
本申请描述的实施方案涉及特殊的油溶性金属添加剂和在润滑油配方中利用该金属添加剂改善配方的抗磨性能。
背景技术
下一代范畴的轿车发动机油和重型柴油发动机油将要求等效的抗磨性能,但配方中磷和硫的含量要低,以便降低更严格的控制污染装置的沾污。众所周知,含硫和磷的添加剂会使成品油具有抗磨性能,但也会抑制或者降低控制污染装置的效力。
二烷基二硫代磷酸锌(“Zn DDPs”)已在润滑油中使用多年。Zn DDPs也具有良好的抗磨性能并被用来通过凸轮磨损试验,例如SeqIVA和TU3磨损试验。很多专利涉及Zn DDPs的制造和应用,包括美国专利4,904,401、4,957,649和6,114,288,它们都全文并入本发明中作为参考。
含硫的抗磨损剂也是公知的,包括二烃基多硫化物,硫化烯烃,硫化的天然和合成来源的脂肪酸酯,三硫酮,硫化的噻吩基衍生物,硫化萜烯,硫化多烯,硫化的Diels-Alder加成物等。具体的实例包括硫化异丁烯,硫化二异丁烯,硫化三异丁烯,二环己基多硫化物,二苯基多硫化物,二苄基多硫化物,二壬基多硫化物,以及二叔丁基多硫化物的混合物,例如二叔丁基三硫化物、二叔丁基四硫化物和二叔丁基五硫化物的混合物。在上述化合物中,硫化烯烃被用于许多用途。在美国专利2,995,569、3,673,090、3,703,504、3,703,505、3,796,661和3,873,454中描述了制备硫化烯烃的方法。也可以使用美国专利4,654,156中描述的硫化烯烃衍生物。在美国专利4,857,214、5,242,613和6,096,691中描述了其它的含硫抗磨剂。
需要一种润滑添加剂,它具有优异的抗磨性能,并且与汽车和柴油发动机中使用的控制污染装置相容得更好。

应该清楚,前面的一般说明和下面的详述都只是示例和解释,用来对所公开并提出权利要求的实施方案作进一步的说明。
具体实施方案
在一项实施方案中展示了一种可作为润滑油组合物申的组分使用的新颖组合物。该组合物含有一种烃溶性钛化合物,它可以作为常规的含磷和硫的抗磨添加剂的补充物或部分替代物使用。
供润滑剂组合物使用的这种添加剂和浓缩物的主要成分是一种烃溶性钛化合物。“烃溶性”一词意味着通过活性钛化合物与烃类物质的反应或络合作用,该化合物基本上悬浮或溶解于烃类物质中。这里所说的“烃”是指其中含有以各种方式结合的碳、氢和/或氧的许多种化合物中的任何一种。
适合用于本发明的钛化合物的实例包括但不限于由酸、醇和二醇衍生的钛化合物,例如钛的羧酸盐、酚盐、醇盐、磺酸盐等。此类化合物在其烃基组分中可以含约5-200个或更多的碳原子。
术语“烃基”是指有一碳原子与分子其余部分直接连结的基团,而且该基团主要具有烃类特点。烃基的实例包括:
(1)烃取代基,即,脂族(例如烷基或链烯基)、脂环族(例如环烷基、环烯基)取代基,和芳基-、脂基-及脂环基取代的芳族取代基,以及环形取代基,其中该环通过分子的另一部分完成(例如,两个取代基合起来形成一个脂环基);
(2)取代的烃基取代基,即,含非烃基团的取代基,该非烃基团就本发明的内容而言不会改变占支配地位的烃取代基(例如卤素(尤其是氯和氟)、羟基、烷氧基、巯基、烷基巯基、硝基、亚硝基和亚硫酰基);
(3)杂取代基,即,取代基在本发明的意义上具有占支配地位的烃类特点,但在其余皆由碳原子组成的环或碳中含有非碳原子。杂原子包括硫、氧、氮,这包括诸如吡啶基、呋喃基、噻吩基和咪唑基等取代基。一般,在该烃基中每10个碳原子中存在的非烃取代基不超过2个,优选不超过1个;通常,在烃基中不含非烃取代基。
适用的钛的醇盐的实例包括但不限于C1-C20钛酸烷基酯,例如辛二醇钛酸酯、钛酸丁酯、聚钛酸丁酯、钛酸四异丙酯、钛酸四壬酯和钛酸异辛酯。也可以使用钛的芳基酯和芳烷基酯,例如钛酸四苯酯、钛酸四苄酯、钛酸二乙基二苯基酯等。合适的钛酸酯的实例可以在美国专利2,160,273、2,960,469和6,074,444中查到。
钛的羧酸盐可以通过有机酸的碱金属盐水溶液、有机酸的胺盐水溶液和/或有机酸的铵盐水溶液与四氯化钛水溶液反应,随后将反应产物氧化制得。钛的羧酸盐的实例包括但不限于甲酸、乙酸、丙酸、丁酸、戊酸、己酸、辛酸、月桂酸、肉豆蔻酸、棕榈酸、硬脂酸、油酸、亚油酸、亚麻酸、环己烷羧酸、苯基乙酸、苯甲酸、新癸酸等的钛盐。
可以使用的其它的钛有机化合物包括但不限于:钛的酚盐,水杨酸盐,磷酸盐和硫化的钛的酚盐,其中各芳族基团均有一个或多个脂族基团以赋予烃溶性;上述任何酚或硫化酚的碱式盐(经常称作“高碱性”酚盐或者“高碱性硫化酚盐”);以及钛的磺酸盐,其中各磺酸部分与一个芳香环连接,该芳香环本身常含有一个或多个脂族取代基以赋予烃溶性;任何上述磺酸盐的高碱性盐(常称作“高碱性磺酸盐”)。上述的磺酸盐、水杨酸盐、磷酸盐和酚盐可以包含钠、钾、钙和/或镁磺酸盐和酚盐与该钛的磺酸盐、水杨酸盐、磷酸盐和酚盐相结合。
本发明所述的实施方案的烃溶性钛化合物被有利地掺合到润滑剂组合物中。该钛化合物可以直接加到润滑油组合物中。然而,在一项实施方案中,用基本上惰性的、通常为液态的有机稀释剂例如矿物油、合成油(即二羧酸的酯)、石脑油、烷基化(例如C10-C13烷基)苯、甲苯或二甲苯,将其稀释成添加剂浓缩物。该钛添加剂浓缩物通常含约0-99%重量的稀释油。
在制备润滑油制剂时,通常的作法是以在烃油,例如矿物油或其它合适溶剂中的1-99%重量活性成分浓缩物的形式加入添加剂。通常这些浓缩物可以按照每份重量添加剂包装物加0.05-10份重量润滑油配制成成品润滑剂,例如齿轮箱机油。浓缩物的目的当然是减少各种材料处理时的困难和不方便,并促进在最终掺混物中的溶解和分散。
用上述的烃溶性钛添加剂制成的润滑剂组合物可用于多种用途。对于压缩点火发动机和火花点火发动机,优选润滑剂组合物符合或超过分布的GF-4或API-CI-4标准。符合上述的GF-4或API-CI-4标准的润滑剂组合物包含一种基油和油添加剂包装物以形成配制好的润滑剂。用于本发明润滑剂的基油是一种具有润滑粘度的润,选自天然润滑油、合成润滑油及其混合物。这类基油包括通常作为火花点火和压缩点火的内燃机(例如汽车和卡车发动机、船只和火车柴油发动机)的曲轴箱润滑油使用的油。
天然油包括动物油和植物油(例如蓖麻油、猪油)、煤油以及石蜡、环烷和石蜡-环烷混合型的氢化精制的、溶剂处理的或酸处理的矿物润滑油。由煤或油页岩衍生形成的具有润滑粘度的油也是适用的基油。本发明中使用的合成润滑油包括通常使用的合成烃油中的任何一种,这包括但不限于:聚α-烯烃,烷基化芳烃,氧化烯聚合物、互聚物、共聚物及其末端羟基通过酯化、醚化等被改性的衍生物,二羧酸的酯和硅油。
全配方的润滑剂通常包括一个添加剂包装物,这里称作分散剂/抑制剂包装物或DI包装物,它们将为制剂提供所需的特性。在例如美国专利5,204,012和6,034,040中描述了合适的DI包装物。在添加剂包装物中所包含的各类添加剂中,有洗涤剂、分散剂、摩擦调节剂、密封溶胀剂、抗氧化剂、抑泡剂、润滑剂、防锈剂、腐蚀抑制剂、破乳剂、粘度指数改进剂等。这些组分中有些是本领域技术人员熟知的,优选以常规数量与所述的添加剂和组合物一起使用。
例如,无灰分散剂包括一个油溶性聚合烃主链,该主链上带有能与要分散的粒子结合的官能团。通常,分散剂包含常通过桥基与聚合物主链连结的胺、醇、酰胺或酯极性部分。该无灰分散剂可以选自例如长链烃取代的单和二羧酸或其酸酐的油溶性盐、酯、氨基酯、酰胺、酰亚胺和噁唑啉,长链烃的硫代羧酸酯衍生物;有多胺与其直接连接的长链脂族烃;以及由长链取代的酚和甲醛及聚亚烷基多胺缩合形成的Mannich缩合产物。
粘度调节剂(VM)的作用是使润滑油具有高温和低温可操作性。使用的VM可以具有单一功能,也可以有多重功能。
同时起分散剂作用的多功能粘度调节剂也是已知的。合适的粘度调节剂是聚异丁烯,乙和丙烯及高级α-烯烃的共聚物,聚甲基丙烯酸酯类,聚甲基丙烯酸烷基酯,甲基丙烯酸酯共聚物,不饱和的二羧酸和乙烯基化合物的共聚物,苯乙烯和丙烯酸酯的共聚物,苯乙烯/异戊二烯、苯乙烯/丁二烯和异戊二烯/丁二烯的部分氛化的共聚物,以及丁二烯和异戊二烯及异戊二烯/二乙烯基苯的部分氢化的均聚物。
氧化抑制剂或抗氧化剂降低基础油料在使用期间变质的趋势,这种变质的证据是氧化产物(例如金属表面上的淤渣和积炭状沉积物)和粘度升高。氧化抑制剂包括位阻酚、最好有C5-C12烷基支链的烷基酚硫酯的金属盐,壬基酚硫化钙,无灰的油溶性酚盐和硫化酚盐,磷硫化或硫化的烃,磷酯,金属的硫代氨基甲酸盐,以及如美国专利4,867,890中所述的油溶性铜化合物。
可使用选自非离子型的聚氧化烯多元醇及其酯,聚氧化烯酚,及阴离子型烷基磺酸的防锈剂。
可以使用少量的破乳组分。EP 330,522中描述了一种优选的破乳组分。该组分通过氧化烯与用双环氧化物和多元醇反应得到的加合物反应制得。破乳剂的用量应不超过活性成分质量的0.1%。处理率为活性成分的0.001-0.05%质量是合适的。
倾点下降剂,或者称为润滑油流动改善剂,能降低流体开始流动或可以倾倒的最低温度。此类添加剂是众所周知的。改善流体的低温流动性的典型的此类添加剂是C8-C18二烷基富马酸酯/乙酸乙烯酯共聚物,聚甲基丙烯酸烷基酯等。
泡沫控制剂可由很多种化合物提供,包括聚硅氧烷型消泡剂,例如硅油或聚二甲基硅氧烷。
如美国专利3,794,081和4,029,587中所述的密封溶胀剂也可以使用。
上述各添加剂,在使用时,均以功能有效数量使用以使润滑剂具有所要求的性能。例如,如果添加剂是一种腐蚀抑制剂,此腐蚀抑制剂的功能有效量应是足以使润滑剂具有所要求的抑制腐蚀特性的数量。一般,这些添加剂在使用时其浓度最高为润滑油组合物重量的约20%,在一项实施方案中为约0.001-20%重量,而在一实施方案中为润滑油组合物重量的约0.01-10%。
钛化合物添加剂可以直接加到润滑油组合物中。但在一项实施方案中,将它们用基本上惰性的、通常呈液态的有机稀释剂稀释,例如用矿物油、合成油、石脑油、烷基化(例如C10-C13烷基)苯、甲苯或二甲苯稀释,形成添加剂浓缩物。这些浓缩物通常含约1-100%重量的钛化合物,在一项实施方案中含约10-90%重量的钛化合物。
适合用来配制本发明所述的组合物、添加剂和浓缩物的基油可以选自任何合成油或天然油或其混合物。合成的基油包括二羧酸烷基酯,聚乙二醇和醇,聚α-烯烃(包括聚丁烯),烷基苯,磷酸的有机酯以及聚硅氧烷油。天然的基油包括矿物润滑油,其来源可以各式各样,例如石蜡型、环烷型或石蜡-环烷混合型。基油通常在100℃的粘度值为约2.5-15厘沲,优选约2.5-11厘沲。
因此,可使用的基油可以选自美国石油学会(API)基油互换性指南中规定的I-V组基油的任何一种。这些组基油列出如下:
1I-III组是矿物油基本油料。
用来配制本发明所述的组合物的添加剂可以各自掺混到基油中或以各种次级组合物的形式掺入。但最好是利用添加剂浓缩物(即,添加剂加上稀释剂,例如烃溶剂)同时掺入所有组分。使用添加剂浓缩物的好处是各组分在以添加剂浓缩物形式组合时的彼此相容性。另外,使用浓缩物减少了掺混时间和发生掺混错误的可能性。
这些实施方案提供了用于内燃机的润滑油,其中所加的烃溶性钛化合物的浓度相对较低,按元素钛计算,在油中形成约50-500ppm的钛。在一项实施方案中,钛化合物在润滑油组合物中的数量足以提供约100-200ppm的钛金属,在另一实施方案中,则提供约120-180ppm的钛金属。
给出以下实施例用来示例说明这些实施方案的各个方面,而不是以任何方式加以限制。
实施例
制备13种全配方的润滑剂组合物,根据欧洲试验规范IP-239用四球磨损试验比较这些组合物的抗磨性质。每种润滑组合物含一份常规的DI包装物,构成润滑剂组合物重量的11%。该DI包装物中包含常规数量的洗涤剂、分散剂、抗磨添加剂、摩擦调节剂、消泡剂和抗氧化剂。配方中还含有约0.1%重量的倾点降低剂,约11.5%重量的烯烃共聚物粘度指数改进剂,约62-63%重量的150号溶剂中性油,约14.5%重量的600号溶剂中性油。样品1不含钛化合物。样品2-13含有数量足以提供约80-200ppm钛金属的钛化合物。在室温下用四球磨损试验在润滑制剂中试验这些样品,采用40kg的重量在1475rpm下试验60分钟。下表中列出了配方和结果。
在上表中使用以下图表符号:
Ti-TEN CEN是OM Group,Inc.(Newark,New Jersey)的一种新癸酸钛,含有约6.7%重量的钛金属。
Ti-2-EHO是2-己基己氧基钛,含约8.7%重量的钛金属。
KR-TTS是得自Kenrich Petrochemicals,Inc.(Bayonne,NewJersey)的三(异十八烷酸根合-O-)-2-丙氧基钛(IV),含约5.5%钛金属。
LICA-01是得自Kenrich Petrochemicals,Inc.的三(新癸酸根合-O-)-2,2-(二2-丙烯氧基甲基)丁氧基钛(IV),含约5.8%钛金属。
KR-12是得自Kenrich Petrochemicals,Inc.的三[(二辛基)磷酸根合-O-]-2-丙氧基钛(IV),含约3.1%钛金属。
KR-9S是得自Kenrich Petrochemicals,Inc.的三(十二烷基苯磺酸根合-O-)-2-丙氧基钛(IV),含约3.5%钛金属。
如上述结果所说明的,样品2-13含有烃溶性钛化合物形式的约80-200ppm钛金属,其性能远优于不含钛金属的常规润滑剂组合物。不含钛金属的样品1有一个直径约0.65mm的磨痕,而含钛的其它样品的磨痕直径为约0.35-0.47mm。可以预料,含有约50-500ppm烃溶性钛化合物形式的钛金属的配方将可以减少常规的含磷和含硫抗磨剂,从而改善车辆上控制污染装置的性能,同时达到类似的抗磨性能或效益。
在本说明书的许多地方提到了很多美国专利。所有这些被引用的文献,如同在本发明中充分阐明的一样,都特地全文并入本发明中。
以上实施方案在实施时容易作很大的变动。因此,实施方案并不想局限于上面提到的具体的实施方案。不如说,以上实施方案是在所附权利要求的精神和范围之内,根据法律还包括其可利用的等价物。
本专利权所有人无意向公众奉献所公开的任何实施方案,而且就所公开的任何修改或变动可能字面上不在权利要求范围之内而言,它们根据等同论都被认为是本发明的一部分。
