Abstract
本发明提供在基油中配合芳烷基化二苯基胺和分子量为340以上的酚类化合物而成的即使在高温下也不易分解、挥发，氧化寿命长，长期维持润滑特性的润滑组合物，特别是提供润滑脂组合物和润滑油组合物。
Description
技术领域
本发明涉及润滑组合物，特别是涉及在汽车、电气设备、建设机械、机床等各种机械装置或轴承的润滑中使用的高温用润滑脂(grease)组合物以及高温下在液压、压缩、真空泵、轴承、齿轮等中长期使用的润滑油组合物。
背景技术
润滑组合物广泛用于汽车、电气设备、建设机械、机床等各种机械中，但是逐年谋求机械的小型化、高输出功率化、轻量化、保守简化，润滑组合物的润滑条件形成日益苛刻的状况。机械的小型化、高输出功率化意味着同一输出功率下、尺寸形状变小，但是若尺寸形状变小则由于从机械表面释放的热量降低，导致润滑部分的温度上升。此外，轻量化由于使用非金属等难以传导热的材料，结果助长温度更加上升。此外，保守的简化意味着使用寿命的延长，因此延长氧化寿命的同时也必须延长润滑特性。由此，期待氧化寿命长、长期维持润滑特性的润滑组合物，特别是高滴点的高温用润滑脂和高温用润滑油组合物。
迄今提出了各种高滴点的高温用润滑脂。例如，专利文献1中公开了含有羟基脂肪酸的锂盐、脂肪族二羧酸的二锂盐或脂肪族单羧酸的锂盐、以及塑料用金属钝化剂的润滑脂。此外，专利文献2中公开了含有合成润滑油构成的基油、脲化合物构成的增稠剂、(a)芳胺类化合物和(b)受阻酯类化合物，进一步含有(c)选自酞酰亚胺类化合物和分子中具有芳环的磷酸酯类化合物中的1种以上化合物的润滑脂组合物。
此外，专利文献3中公开了在基油中配合增稠剂、抗氧化剂和芳族二元酸或芳族二元酸金属盐(但是对苯二甲酸锂除外)而成的润滑脂组合物。
而专利文献4中公开了将含有分子中具有1个以上羟基的碳原子数为12～24的脂肪酸和碳原子数为2～12的脂肪族二羧酸的锂盐的增稠剂配合在以40℃下的运动粘度为300～500mm2/s的矿物油和40℃下的运动粘度为20～300mm2/s的合成烃油为必须成分且其40℃下的运动粘度为60～200mm2/s的基油中而得到的润滑脂组合物。
进一步地，专利文献5中公开了含有(a)异氰酸酯基的含量为6～10重量％的氨酯预聚物、(b)选自金属皂型润滑脂和非金属皂型润滑脂中的润滑脂、和(c)胺类固化剂，固化后的硬度以国际橡胶硬度单位(1RHD)计为60～85的滚动轴承用润滑组合物。
上述发明都是谋求高温下长寿命化的发明，但是仍然不能充分地适于最近苛刻的条件。
此外，专利文献6中，作为润滑组合物用抗氧化剂提出了苯乙烯化二苯基胺、特别是4，4’-二(α-甲基苄基)二苯基胺。但是，未考虑与其它的抗氧化剂的并用。
进一步地，专利文献7中，以耐磨损性和提高氧化稳定性为目的，提出了在基油中含有非离子类表面活性剂或防磨损剂的同时，还含有烷基化二苯基胺或受阻酚类作为抗氧化剂而得到的耐磨损性轴承油组合物。但是未提示谋求高温下的长寿命化而并用胺类抗氧化剂和酚类。
因此实际情况是：为了提高润滑油在高温时的防氧化老化性，胺类抗氧化剂和酚类抗氧化剂的有利的组合的开发还不充分。

发明内容
本发明是为了解决上述问题而提出的，其目的在于，提供即使在高温下也不易分解、挥发，氧化寿命长，长期维持润滑特性的润滑组合物，特别是润滑脂组合物和润滑油组合物。
本发明人为了达成上述目的而进行精心研究，结果发现，通过在基油中配合芳烷基化二苯基胺和特定的酚类化合物，可以达成该目的。基于该发现完成本发明。
即，本发明是在基油中配合芳烷基化二苯基胺和分子量为340以上的酚类化合物而得到的润滑组合物。
具体实施方式
作为本发明的润滑组合物中所使用的基油，不特别限定，可以使用以往公知的矿物油、合成油的任意一种，例如，除了石蜡类、中间基类(中間基系)或环烷类等矿物油或对这些矿物油进行溶剂脱沥青、溶剂萃取、氢化分解、溶剂脱蜡、氢化脱蜡或氢化纯化得到的纯化矿物油，将蜡异构化得到的矿物油，或聚-α-烯烃等烃类合成油、油脂类之外，还可以使用合成酯类、合成醚等。其中优选为纯化矿物油或合成油。更具体地说，为闪点180℃以上、优选200℃以上的基油。若闪点为180℃以上则适合用作高温用润滑脂组合物。此外，基油的％CA优选为1以下，进一步优选为0.5以下。其中，CA是指n-d-M环分析(ASTM D 3238)中的芳族成分，基油的％CA是指基油的CA的质量％。进一步地，基油中所含有的硫成分优选为20ppm以下，特别优选为10ppm以下。
此外，作为本发明中用作基油的聚-α-烯烃，可以使用各种聚-α-烯烃，通常是碳原子数为6～18的α-烯烃的聚合物且具有润滑粘度的聚-α-烯烃。其中，作为优选的聚-α-烯烃，从热稳定性、密封性、润滑性等方面考虑可以举出1-十二碳烯、1-癸烯或1-辛烯的聚合物。而且，本发明中，作为聚-α-烯烃，从热稳定性方面考虑特别是优选使用其氢化处理物。这些聚-α-烯烃可以单独使用或混合使用。
对基油的运动粘度不特别限定，但是通常优选从40℃下2～600mm2/s，进一步优选从10～400mm2/s中适当选择。
其次，作为本发明的润滑组合物中所使用的芳烷基化二苯基胺，优选为下述化学式(1)所示的化合物。
上述化学式(1)中，R1和R4优选各自独立地是碳原子数为0～24的烷基，R2和R3优选各自独立地是碳原子数为1～5的亚烷基，进一步优选碳原子数为1～3的亚烷基。其中，碳原子数为0指的是不存在R1和R4。
作为芳烷基化二苯基胺的具体例子，可以举出4，4’-二(α，α-二甲基苄基)二苯基胺、4，4’-二苄基二苯基胺、4，4’-二苯乙基二苯基胺、4，4’-二(α-甲基苄基)二苯基胺等，从延长氧化寿命方面考虑，优选为4，4’-二(α，α-二甲基苄基)二苯基胺。
作为芳烷基化二苯基胺的用量，以润滑组合物为基准，优选为0.01～10质量％，进一步优选为0.1～5质量％，特别优选为0.1～2质量％。这是由于若为0.01质量％以上则发挥防止氧化老化的效果、若为10质量％以下则在经济上有利。
此外，作为本发明中所使用的分子量为340以上、优选为350以上的酚类化合物的优选例子，可以举出下述化学式(2)所示的酚类化合物。
上述化学式(2)中，R5优选是碳原子数为1～18的烷基，R6优选是碳原子数为1～5的亚烷基，特别优选是碳原子数为1～3的亚烷基，R7优选是碳原子数为1～24的烷基，n为1或2。
作为上述化学式(2)的化合物的具体例子，可以举出十八烷基-3-(3，5-二叔丁基-4-羟基苯基)丙酸酯(分子量：520.89)。
进一步地，作为本发明中所使用的分子量为340以上的酚类化合物的其它优选例子，可以举出双酚化合物。作为其具体例子，可以举出2，2’-亚甲基二(4-甲基-6-叔丁基苯酚)(分子量：340.51)、2，2’-亚甲基二(4-乙基-6-叔丁基苯酚)(分子量：368.54)、4，4’-硫基(thio)-(3-甲基-6-叔丁基苯酚)(分子量：358.55)、4，4’-亚丁基二(3-甲基-6-叔丁基苯酚)(分子量：382.59)、4，4’-亚甲基二(2，6-二叔丁基苯酚)(分子量：424.68)、3，9-二[1，1-二甲基-2-[β-(3-叔丁基-4-羟基-5-甲基苯基)丙酰氧基]乙基]2，4，8，10-四氧杂螺[5，5]十一烷(分子量：740.98)等。
而且，作为本发明中所使用的分子量为340以上的酚类化合物的另外其它的优选例子，可以举出双酚类化合物以外的其它多酚化合物。可以举出例如，1，1，3-三(2-甲基-4-羟基-5-叔丁基苯基)丁烷(分子量：544.83)、1，3，5-三甲基-2，4，6-三(3，5-二叔丁基-4-羟基苄基)苯(分子量：775.21)、四-[亚甲基-3-(3’，5’-二叔丁基-4’-羟基苯基)丙酸酯]甲烷(分子量：1177.66)、二[3，3’-二-(4’-羟基-3’-叔丁基苯基)丁酸]乙二醇酯(分子量：794.42)、1，3，5-三(3’，5’-二叔丁基-4’-羟基苄基)-S-三嗪-2，4，6-(1H，3H，5H)三酮(分子量：784.09)。
此外，作为本发明中所使用的分子量为340以上的酚类化合物的其它的优选例子，也使用生育酚(分子量：430.71)及其衍生物。
若上述酚类化合物的分子量为340以上则防氧化老化的效果显著，若为350以上则更显著而更优选。此外，若分子量为1500以下则不会出现在基油中的溶解性差而优选。
以上举出的例子中，作为分子量为340以上的酚类化合物，十八烷基-3-(3，5-二-叔丁基-4-羟基苯基)丙酸酯(分子量：520.89)或2，2’-亚甲基二(4-乙基-6-叔丁基苯酚)(分子量：368.54)从提高防氧化老化效果的方面考虑特别优选。
作为分子量为340以上的酚类化合物的用量，以润滑组合物为基准，优选为0.01～10质量％、更优选为0.1～5质量％、特别优选为0.1～3质量％。这是由于若为0.01质量％以上则发挥防氧化老化效果、若为10质量％以下则在经济上有利。
其次，作为本发明中所使用的增稠剂，不特别限定，可以使用皂类、非皂类的任意一种。优选润滑脂组合物的滴点为230℃以上的增稠剂。这是由于若润滑脂组合物的滴点为230℃以上则抑制产生润滑上的问题，例如高温下的软化或随之的泄漏、烧粘等的可能性。
作为皂类，可以举出用碱金属或碱土金属等金属氢氧化物将羧酸或其酯皂化得到的金属皂。作为金属，可以举出钠、钙、锂、铝等，作为羧酸，可以举出油脂或将其水解除去甘油得到的粗制脂肪酸，硬脂酸等单羧酸，12-羟基硬脂酸等单羟基羧酸，壬二酸等二元酸，对苯二甲酸、水杨酸、苯甲酸等芳族羧酸。它们可以单独使用或复合使用。具体地说，优选为使用12-羟基硬脂酸的锂皂。配合该皂类的增稠剂时，也可以在基油中投入羧酸和上述金属氢氧化物、在基油中皂化。
此外，作为其它的皂类增稠剂，可以举出各种复合皂。
作为该复合皂，使用锂复合皂、铝复合皂、钙复合皂等。其中，锂复合皂通过使硬脂酸、油酸、软脂酸等脂肪酸和/或分子中具有1个以上羟基的碳原子数为12～24的羟基脂肪酸，和芳族羧酸和/或碳原子数为2～12(更优选碳原子数为4～9)的脂肪族二羧酸与诸如氢氧化锂等锂化合物反应来得到，与锂皂相比，其耐热性优异，所以作为增稠剂更优选。作为上述碳原子数为12～24的羟基脂肪酸，最优选为12-羟基硬脂酸，但是也可以使用所有其它的羟基脂肪酸。作为其它的可以使用的羟基脂肪酸，可以举出例如12-羟基月桂酸、16-羟基软脂酸等。而且，作为芳族羧酸，可以举出苯甲酸、邻苯二甲酸、间苯二甲酸、对苯二甲酸、偏苯三酸、均苯四甲酸、水杨酸、对羟基苯甲酸等。此外，作为上述碳原子数为2～12的脂肪族二羧酸，最优选为壬二酸，但是也可以使用所有其它的脂肪族二羧酸。作为其它的可以使用的脂肪族二羧酸，可以举出例如，癸二酸、草酸、丙二酸、琥珀酸、己二酸、庚二酸、辛二酸、十一烷二酸、十二烷二酸等。其中，在脂肪酸和/或分子中具有1个以上羟基的碳原子数为12～24的羟基脂肪酸、以及芳族羧酸和/或碳原子数为2～12的脂肪族二羧酸的总质量中，优选芳族羧酸和/或碳原子数为2～12的脂肪族二羧酸为20～90质量％。若在20～90质量％的范围内则得到对热稳定的增稠剂，对于润滑脂组合物在高温下实现长寿命化是有利的。
此外，作为非皂类，使用脲化合物或经过有机处理的膨润土等。
其中，作为用作增稠剂的脲化合物，可以举出二脲化合物、三脲化合物、四脲化合物，此外，也包括脲-氨基甲酸酯化合物。
脲化合物由于耐热性、耐水性都优异，特别是高温下的稳定性优异，适合用于高温部位。
作为上述二脲化合物，可以举出例如R8NHCONHR9NHCONHR8所示的化合物(式中，R8表示碳原子数为6～24的直链状或支链状的饱和或不饱和的烃基，R9表示碳原子数为6～15的2价芳烃基。)，作为代表性的二脲化合物，为二异氰酸酯与单胺反应得到的二脲化合物，作为二异氰酸酯，可以举出二苯基甲烷二异氰酸酯、亚苯基二异氰酸酯、二苯基二异氰酸酯、苯基二异氰酸酯、亚苄基二异氰酸酯等，作为单胺，可以举出辛胺、十二烷胺、十六烷胺、环己胺、苯胺、甲苯胺、十八烷胺、油胺等，但是也可以使用以往公知的脲类增稠剂的任意一种。
上述各种增稠剂中，优选为各种复合皂或脲化合物，上述各种复合皂和脲化合物可以并用2种以上。
上述各种增稠剂在润滑脂组合物中的配合量若在得到润滑脂性状的范围内则不特别限定，以润滑脂组合物为基准，优选为10～30质量％、更优选为10～20质量％。
本发明的润滑脂组合物中所使用的增稠剂用于赋予稠度，若配合量过少则得不到所期望的稠度，另一方面若配合量过多则润滑脂的润滑性降低。
对于本发明的润滑脂组合物，为了长期维持高温时的润滑特性，优选在闪点为180℃以上的基油中配合芳烷基化二苯基胺和分子量为340以上的酚类化合物，进一步配合增稠剂。
在本发明的润滑脂组合物和润滑油组合物中，除了上述试剂之外，还可以加入任意的防锈剂、极压添加剂、金属钝化剂、金属类洗涤剂、非金属类洗涤剂、消泡剂、增粘剂、着色剂、防水剂等添加剂。
作为防锈剂，可以举出金属类磺酸盐、琥珀酸酯等。作为金属类洗涤剂，可以举出金属磺酸盐、金属水杨酸盐、金属フイネ一ト等。作为非金属类洗涤剂，可以举出琥珀酰亚胺等。作为金属钝化剂，可以举出苯并三唑、噻二唑等。作为消泡剂，可以举出甲基硅酮、二甲基硅酮、氟硅酮、聚丙烯酸酯等。
通过本发明，可以提供即使在高温下也不易分解、挥发，氧化寿命长，长期维持润滑特性的润滑组合物，特别是润滑脂组合物和润滑油组合物。
