Description

液压用液体
本发明涉及一种液压用液体。
发明背景
WO93/03121涉及液压用液体，当该油暴露于水时，其具有改进的过滤性和具有增加的抗锌损失性。这些组合物包括(A)选自磺酸盐、酚盐、羧酸盐及其混合物的金属盐的组合，(B)脂肪族羧酸或酸酐、或其含有羧酸基团的衍生物，其中该脂肪族基团含有至少20个碳原子，以及任选的(C)至少一种有机磷酸的(C)(I)的金属盐或至少一种有机磷酸的(C)(I)和至少一个羧酸基团(C)(II)的混合物，以及任选的(D)三唑。在一个实施方案中，(A)的羧酸为芳香族羧酸。这些芳香族羧酸、特别是水杨酸的锌、钙和镁盐是优选的。虽然水杨酸镁和二硫代磷酸锌本身都被提到过，但没有关于将这些化合物组合使用的教导。
WO 89/04358涉及组合物，该组合物包括(A)酸性有机化合物的中性或碱性金属盐，(B)金属减活化剂、优选为非必须取代的苯并三唑，以及(C)选自(C-1)含磷酰胺、(C-2)含磷酯、(C-3)硫连结的二硫代氨基甲酸盐、(C-4)根据式(I)的含硫化合物的含硫和/或含磷化合物。特别优选的盐(A)为钠盐、镁盐、钙盐或其两种或多种的混合物。在可能出现的进一步列出的其它化合物中，提到的有二烷基二硫代磷酸锌。虽然水杨酸镁和二硫代磷酸锌本身都被提到过，但没有关于将这些化合物组合使用的教导。
EP-A-604 218描述了包括大量具有润滑粘度的油、至少一种二硫代磷酸金属盐、水杨酸锌盐、和锈抑制剂的功能化液体，该液体含有小于约1％wt的分散剂和小于约1％wt的碱性磺酸盐。该二硫代磷酸是最普通的二烃基二硫代磷酸；该金属最优选为锌。该文件的教导被限制在水杨酸锌的使用上。
在US-A-4,627,928中，描述了一种用于制备碱性水杨酸镁的方法，其特征在于镁含量为基于出现的总酸量的镁的化学计量当量的至少150％至高至500％。获得的镁盐被描述为适合用作通常的添加剂、更特别是作为各种润滑油和例如汽油和柴油燃料的燃料的添加剂。其提到这些特殊的水杨酸镁可与其它化合物在宽范围内组合使用。没有公开和教导在液压用液体中使用二硫代磷酸锌和水杨酸镁的组合。
液压用液体需要满足如润滑和传递压力二者的特殊要求。为满足这些要求，液压用液体包含有添加剂。通常，液压用液体包含有抗磨/极度压力的添加剂。对液压用液体而言，在叶片泵中的条件是特别困难的，在此叶片尖端在重负荷和高温下以高速抵靠汽缸滑动。此外，现代液压设备的增加的高操作温度要求液体热稳定以避免沉积物和淤渣的形成和抗铁和非铁金属二者的腐蚀。对含有抗磨添加剂的液压用液体中的良好热稳定性的要求意味着这些添加剂常常与清净剂组合使用。然而，通常使用的烷基苯磺酸的钙盐、烷基萘磺酸的钙盐、石油磺酸的钙盐、烷基酚的钙盐、烷基硫化酚的钙盐或烷基水杨酸的钙盐会使磨损增加。在叶片泵中、更尤其是在低负荷条件下，该磨损的增加特别明显。实际上，当泵停止时会产生低负荷状态。
发明概要
目前人们已惊讶地发现含有水杨酸镁和二硫代磷酸锌组合的液压用液体与含有水杨酸钙组合的液压用液体相比，能改进低负荷下的性能。此外，发现这种组合也提供了更好的热稳定性。当对本发明的液压用液体进行Cincinnati Milacron热稳定性试验时，形成的淤渣和沉积物较少。
本发明提供了一种液压用液体，其包括一润滑基础油、及与之组合的(a)0.001-5％wt的水杨酸镁、(b)0.01-8％wt的二硫代磷酸锌，它们的量以液压用液体的总重量为基础。
本发明还提供了如下组合物在液压用液体中于低负荷下改进耐磨性能的应用，该组合物包括润滑基础油和与之组合的
(a)0.001-5％wt的水杨酸镁，
(b)0.01-8％wt的二硫代磷酸锌。
发明的详细描述
在更低的温度下更容易起动并因此改进发动机在那些环境温度下的启动性)，US-A-5558802描述到可同时避免使用这些盐或以在每100g润滑剂中不超过0.0007摩尔的钙盐的量来使用这些盐。
WO-A-96/37582描述了用于内燃机、自动传递齿轮箱、减震器、动力转向装置等的润滑油组合物。
在WO-A-96/37582中描述的润滑油包括具有特定烷基的次硫酸钼(sulfoxymolybdenum)二硫代氨基甲酸酯、具有特定烷基的二烷基二硫代磷酸锌、特定的烷基水杨酸盐，并且如果需要可包括含硼的琥珀酰亚胺，它们各自以基于润滑油基本油料的预定量存在。
US-A-4462918描述了一种润滑油组合物，其包括主要比例的润滑油和各自较小比例的第II族金属的二硫代磷酸盐和由下式表示的组分：R1O.CO.CR2(NR3R4).CR6R7.CO.OR5，在此R1、R2、R3、R4、R5、R6和R7为氢或包含1-30个碳原子的烃基、并且在此R3、R4独立选自氢、包含1-30个碳原子的烃、和包含1-30个碳原子的酰基。
发明概要
目前人们已惊讶地发现含有水杨酸镁和二硫代磷酸锌组合的液压用液体与含有水杨酸钙组合的液压用液体相比，能改进低负荷下的性能。此外，发现这种组合也提供了更好的热稳定性。当对本发明的液压用液体进行Cincinnati Milacron热稳定性试验时，形成的淤渣和沉积物较少。
本发明提供了一种液压用液体，其包括一润滑基础油、及与之组合的(a)0.001-5％wt的水杨酸镁、(b)0.01-8％wt的二硫代磷酸锌，它们的量以液压用液体的总重量为基础。
发明的详细描述
用于本发明的水杨酸镁可以是中性或高碱性的。术语“高碱性”等效于“碱性”、“超碱性”(superbased)、“过碱性”(hyperbased)和“高金属含量盐”(high-metal containing salts)。水杨酸镁含有过量的金属，该过量是指与按照金属和与该金属反应的水杨酸的化学计量应存在的金属量相比而言。这种中性和碱性金属盐的制备方法是本领域公知的。中性盐可通过将酸性有机化合物的矿物油溶液和与化学计量当量的如金属氧化物、氢氧化物、碳酸盐、碳酸氢盐或硫化物的金属中和剂一起在50℃以上的温度下加热，并过滤得到的物质而制备。碱性盐除使用过量于化学计量的金属外，采用类似的方法制备。
优选使用高碱性的水杨酸镁。这些组合物以它们的总碱值(TBN)来表征。该总碱值优选至少为100mg KOH/g。更优选为至少200mgKOH/g，最优选为至少300mg KOH/g。该总碱值优选最多为600mgKOH/g。另一表征高碱性水杨酸镁的方法是以相对于基于出现的总酸量的化学计量镁当量的镁含量来表征的。本发明使用的高碱性水杨酸镁优选具有大于基于出现的总酸量的化学计量镁当量的500％的镁含量，更优选至少550％。
所述水杨酸盐或被取代或不被取代。适合的取代基包括含有1-40个碳原子和任选含有一个或多个氧和/或氮原子的脂肪族基团、以及羟基基团。优选的取代基为含有6-30个碳原子、优选含有12-20个碳原子的烷基。优选的取代基为线形。该水杨酸盐可含有1-4个、优选1-3个、最优选1-2个取代基。最优选的是该水杨酸盐被一个含有14-18个碳原子的线形烷基所取代。
通常，单-烷基水杨酸是通过酚烷基化和接下来的羧基化而制备的。因此，在单-烷基水杨酸盐中可能出现少量(通常为最多20％mol)的二烷基水杨酸盐和未取代的水杨酸盐。
用于本发明的水杨酸镁是在商业上可得到的。一种适合的商业产品是SAP 007(出自Infineum)。该水杨酸镁通常与矿物油组合使用。在该文献中提到的用量与化合物本身有关，而与矿物油无关。
在US-A-4,627,928中已描述了一种可用于制备适合的水杨酸镁的方法。
二硫代磷酸锌是本领域公知的。用于本发明的优选二硫代磷酸盐由下式表示：
