Description

具有改进的粘度性质的动力传动液
技术领域
本发明涉及新型共聚物，其可用在动力传动液中以提供改进的粘度性质。
背景技术
各种车辆动力传动系统，例如自动变速、手动变速、无极变速等，是本领域中公知的。始终在设计新的动力传动系统，且传统动力传动系统不断被重新设计，以提供改进的车辆可操作性、可靠性和燃料经济性。
通常，新的或重新设计的动力传动系统需要专门配制的动力传动液，以符合其性能规格。该传动液必须符合车辆制造商设定的标准。例如，通用汽车(General Motors)在配备Hydra-Matic变速箱的2006年出厂轿车和卡车中引入自动传动液的Dexron-VI规格。该Dexron-VI规格逐步提高性能要求，以适应传动设计变化以及汽车制造商推进传动液维持更长时间和更好发挥作用的努力。该Dexron-VI规格要求动力传动液表现出小于或等于15,000厘泊(cP)的在-40℃的流体粘度。
为了提供能达到必要性能要求的动力传动液，必须以特定比例将一种或多种下列添加剂组分与基油混合：粘度改进剂、润滑油流动性改进剂(“LOFIs”)、摩擦改进剂、分散剂、金属清净剂、抗磨剂、粘度改进剂(VM)等。一般而言，这些类型的组分是本领域中公知的，但不断地发明各种组分的具体化学组成。
本发明提供了具有LOFI和VH特性的新型共聚物，其可用在动力传动液中以提供改进的粘度性质。该共聚物包含在侧链中的平均碳原子数为大于8至小于12(使用特定公式计算)的醇的混合物。该共聚物可以表现出0.10至1.00的增稠率(“TE”)。
发明概要
在非限制性实施方案中，本发明是用于动力传动液的共聚物，其包含具有平均碳数(Cn)为大于8至小于12的侧链的醇的混合物，该平均碳数通过下式确定：
C n = Σ i = j i = z X i Cn i Σ i = j i = z X i
其中Xi是醇(i)的摩尔份数；Cni代表醇(i)中的碳原子数；j是该共聚物中的醇中的最低碳数并且必须为至少6；z是醇中的最高碳数。
在另一非限制性实施方案中，本发明是动力传动液组合物，其包含：(a)基油，其包含第II类基础油料、第III类基础油料和/或第IV类基础油料及其混合物；和(b)共聚物，其包含具有平均碳数(Cn)为大于8至小于12的侧链的醇的混合物，该平均碳数通过下式确定：
C n = Σ i = j i = z X i Cn i Σ i = j i = z X i
其中Xi是醇(i)的摩尔份数；Cni代表醇(i)中的碳原子数；j是该共聚物中的醇中的最低碳数并且必须为至少6；z是醇中的最高碳数。
发明详述
除非另行指明，说明书和权利要求中所用的表示成分量、反应条件、尺寸、物理特性、加工参数等的所有数字被理解为在所有情况下都用术语“大约”修饰。相应地，除非作出相反的指示，下列说明书和权利要求中所列的数值可以根据试图通过本发明获得的所需性质而变。至少地且不是企图限制对权利要求的范围适用等同原则，各数值应至少根据所报道的有效位数和通过应用普通舍入技术来解释。此外，本文公开的所有范围被理解为包括开端和末端范围值以及其中包含的任何和所有子范围。例如，“1至10”的所述范围应该被认为包括在最小值1和最大值10之间(包括端点)的任何和所有子范围；即，以最小值1或更大值开始并以最大值10或更小值结束的所有子范围，例如5.5至10。在下列说明书中在任何时候提到美国专利或专利文献或参考文献时，也将该文献经此引用并入本文，并且被理解为全文并入。
本说明书通篇使用各种术语。下面提供其中一些术语的定义。
根据American Petroleum Institute(API)出版物“Engine Oil Licensingand Certification System”，Industry Services Department，第14版，1996年12月，附录1，1998年12月中提供的定义规定术语“基础油料”。根据使用指定试验测得的下述指定标准，将基础油料分类为第I类、第II类、第III类、第IV类或第V类。
第I类基础油料含有少于90％的饱和物和/或多于0.03％的硫，并具有大于或等于80且小于120的粘度指数。
第II类基础油料含有大于或等于90％的饱和物和小于或等于0.03％的硫，并具有大于或等于80且小于120的粘度指数。
第III类基础油料含有大于或等于90％的饱和物和小于或等于0.03％的硫，并具有大于或等于120的粘度指数。
第IV类基础油料是聚α烯烃(PAO)，其是合成基础油料。
第V类基础油料包括不能被归类为第I、II、III或IV类基础油料的所有其它基础油料。
术语“增稠率”(TE)描述了聚合物每单位质量将油增稠的能力，并被规定为：
Figure G2009102636129D00031
其中c是聚合物浓度(聚合物克数/100克溶液)，kv油+聚合物是该聚合物在参比油中的动粘度，kv油是参比油的动粘度。
术语“分子量”(Mw)是指重均分子量。在本文中，基于聚苯乙烯校准，使用凝胶渗透色谱法测定Mw值。
本发明是用于润滑剂组合物的新型共聚物。该共聚物包含具有平均碳原子数(Cn)为大于8至小于12的侧链的醇的混合物，该平均碳原子数通过下式确定：
C n = Σ i = j i = z X i Cn i Σ i = j i = z X i
其中Xi是醇(i)的摩尔份数；Cni代表醇(i)中的碳原子数；j是该共聚物中的醇中的最低碳数并且必须为至少6；z是醇中的最高碳数。
下面提供如何计算Cn的实例。假设有包含下述醇的混合物的共聚物：0.2摩尔份数的带有四(4)碳侧链的醇；0.2摩尔份数的带有八(8)碳侧链的醇；0.3摩尔份数的带有十(10)碳侧链的醇；和0.3摩尔份数的带有十二(12)碳侧链的醇。该共聚物具有醇的混合物，其中醇侧链的平均碳原子数等于(0.2×8+0.3×10+0.3×12)/(0.2+0.3+0.3)＝10.25。需要指出，在计算中不包括在其侧链中具有少于6个碳原子的醇，例如0.2摩尔份数的带有四(4)碳侧链的醇。
对构成该共聚物的各种醇而言，侧链中的平均碳原子数是重要的，因为其决定该共聚物的结晶温度。该共聚物的结晶温度影响该共聚物如何与润滑剂组合物中的蜡相互作用。
本发明的共聚物可以包含各种单体。在本发明的一个非限制性实施方案中，该共聚物包含第一单体，即，不饱和二羧酸与具有大约C6至大约C24碳原子的烷基的酯，其中醇的侧链中的平均碳原子数为大于8至小于12。
在本发明的另一非限制性实施方案中，该共聚物包含富马酸酯-乙酸乙烯酯(“FVA”)共聚物。该FVA共聚物可以如本领域公知的那样由二羧酸酯制备。其它合适的二羧酸酯可以由下述通式表示：
Figure G2009102636129D00051
式I
其中R是C6至C18直链烷基，R1选自由氢和COOR组成的组，且R2是氢或C1至C4烷基，例如甲基。
Figure G2009102636129D00052
式II
其中R是C6至C18直链烷基，R1选自由氢和COOR组成的组，且R2是氢或C1至C4烷基，例如甲基。
上述二羧酸酯的实例包括富马酸酯和马来酸酯，例如富马酸二癸基酯、富马酸癸基-十二烷基酯、富马酸二(十二烷基)酯、富马酸十二烷基-十六烷基酯、马来酸十二烷基酯等等。
在本发明的该实施方案中，该FVA聚合物可以含有40至60摩尔％的富马酸酯和60至40摩尔％的乙酸乙烯酯。富马酸二烷基酯的烷基中50至100重量％可以为C6至C24。
在本发明的又一非限制性实施方案中，该共聚物包含马来酸酯乙酸乙烯酯(“MVA”)共聚物。在本发明的另一实施方案中，该共聚物包含FVA共聚物和MVA共聚物的组合。
本发明的共聚物可以通过本领域公知的各种方法形成。在本发明的一个非限制性实施方案中，该共聚物通过含有0.5摩尔份数的具有十(10)个碳原子的醇和0.5摩尔份数的具有十二(12)个碳原子的醇的二羧酸酯的自由基聚合形成。
在本发明的另一非限制性实施方案中，该共聚物通过如本领域公知的那样使富马酸二烷基酯(DAF)和乙酸乙烯酯(VA)聚合来形成。
在本发明的一个非限制性实施方案中，该共聚物表现出0.10至1.00的增稠率(“TE”)。

实施例
通过下列非限制性实施例例证本发明。以下述方式形成本发明的共聚物。首先合成C10-C12富马酸酯单体。在装配用于迪安斯塔克酯化的2升RB烧瓶中合并表1中所示的反应物。将反应物在搅拌下加热至130℃达9小时。
使烧瓶冷却，并将该溶液用两(2)份500毫升5％NaOH(水)溶液洗涤，然后用三(3)份500毫升蒸馏水洗涤。形成甲苯层。用无水MgSO4干燥甲苯层，过滤并在100℃/0毫巴旋转蒸发90分钟。上述步骤产生了821.20克富马酸酯单体。

然后，由单体合成C10-C12富马酸酯-乙酸乙烯酯共聚物。将如上制成的富马酸酯单体装入高压釜反应器。将该反应器的内容物加热至60℃以使富马酸酯单体熔融，然后用氮吹扫反应器以除氧。然后，向反应器中加入22.85克脱气的乙酸乙烯酯和32.05克环己烷。将高压釜密封，加热至117℃，并用氮调节压力至4.2巴。
在使反应器稳定后，使用标准高效液相色谱泵经110分钟以恒定速率向该高压釜中加入在环己烷中包含5.78重量％过氧过新戊酸叔丁酯的引发剂溶液。使反应器内容物静置15分钟，然后排空到500毫升圆底烧瓶中。在旋转蒸发器上将所得溶液在100℃和20毫巴真空汽提90分钟。上述步骤产生了146.33克共聚物。
对该共聚物进行数项分析试验。在40℃在甲苯中2重量％/体积％测量该共聚物的比粘度。测得的比粘度为0.23。使用凝胶渗透色谱法(GPC)测量该共聚物的Mw。测得的Mw为大约30,000道尔顿。
