公开了一种含大量烃油和足以改进工作液性能的少量新型添加剂的多功能工作液。其中添加剂包含一种钙盐络合物、一种II族金属的二硫代磷酸盐、一种含硼环氧化物和一种羧酸增溶剂,在工作液中一般含有象粘度改进剂和消泡剂一类的其它组分。所得工作液具有改进的低温流动性和过滤性,改进的耐极端压力/抗磨性能、优良的摩擦改进性质和抗震动能力,以及能够通过液压/传动试验、动力转向和制动器能力的试验。改进的容水性可在不损害改进的耐极端压力性能的同时得到保持。

Description

工作液是包含包括拖拉机工作液、自动传动液、手动传动液、液压液、动力转向液、用于动力系统部件的工作液和能以各种不同功率发挥作用的工作在内而又不限于这些的各种工作液的一种术语。应该注意,上述工作液的每种,例如,自动传动液,就有各种不同类型的自动传动液,因为不同的传动方式具有不同的设计,由此,导致需要工作特性明显不同的传动液。有一种工作液通称为拖拉机工作液,可用于各种类型的拖拉机设备,以保证拖拉机的传动装置、齿轮系统、轴承、液压系统、动力转化装置、机械动力输出装置和油浸制动器的操作。
包含在象拖拉机工作液之类的工作液内的组分,必须仔细加以择选,以便使最终所得的工作液组成可以提供所要求的全部必要的特性,并通过各种不同类型的试验。总之,拖拉机工作液必须起润滑剂、动力传递工具和传热工具的作用。
拖拉机工作液具有许多重要的特性,以保证在拖拉机设备内工作。这些特性包括:能为防止油浸制动器的湿制动器震动提供适当的摩擦性能,同时能推动湿制动器和提供动力输出离合器工作性能。拖拉机液压液必须提供足够的耐磨和耐极端压力性质,以及容水性能/过滤性能。
拖拉机工作液的耐极端压力性质,可以由其通过螺旋伞齿轮试验和直齿正齿轮试验的能力而显示出来。拖拉机工作液必须通过湿制动震动试验,并当用在由青铜、石墨组合物和石棉构成的油浸盘式制动器中时,提供适当的湿制动器能力。拖拉机工作液必须对诸如包括石墨和青铜离合器之类的功率变换传动离合器显示其提供摩擦保留的能力。
第4,410,438号美国专利公开了一种润滑剂和液态燃料的组合物。该组合物包括含硼环氧化物,后者可由其能用在热交换液,传动液和液压液等类工作液中得到说明。
第3,933,659号美国专利公开了一种用于润滑油组合物的工作液,该组合物由大量润滑粘度的油和有效量的添加剂组成。添加剂包括:有效量的碱性琥珀酰亚胺、二烃基二硫代磷酸的第Ⅱ族金属盐、碱性硫化碱土金属烷基酚盐和脂肪酸酯、脂肪酸酰胺或脂肪酸胺、或其混合物的组分。该专利中指出,该润滑组合物可在需要液体离合器,液压液和(或)相对运动部件的润滑等系统中用作工作液。该润滑组合物可用在自动传动装置中,特别是用在客车的自动传动装置中。
第4,116,877号美国专利公开了一种与弹料相容的密封溶胀添加剂。这种添加剂可与自动传动、动力传动液和液压转向液连用。这种工作液是含有油溶性二烃基亚磷酸酯和油溶性烃基取代酚的矿物润滑基础油,其中亚磷酸酯和酚的比重比保持一定。该专利指出,按特别公布的比加入这些特别的添加剂化合物,可给工作液提供强化的弹料相容性。
1984年7月11日公布的公开欧洲专利申请第113,199号中公开了一种拖拉机液压液,该液压液含有拖拉机抗摩液压液中的亚磷酸油基酯以及含琥珀酸十八烯基酯的拖拉机液压液。
申请日为1976年10月13日的英国专利1,452,513号公开了用于拖拉机湿制动系统的含脂肪酸和脂肪酸酰胺的润滑剂组合物。发现这类组合物可以用来降低大温度范围内的噪声量。
1,440,261号英国专利公开了一种用于降低拖拉机湿制动系统噪声的组合物。这种工作液由一种润滑油和一种混有硬脂酸的洗涤剂或分散剂组成。据说这种组合物还包含有亚烷基聚胺分散剂、钙和钡的磺酸盐和酚盐、抗磨-抗氧化剂和油酸。
本发明公开了由大量烃油和足以改进工作液特性(例如润滑剂性能、 动力传递剂性能和热传递剂性能)的少量添加剂组成的工作液,特别是拖拉机工作液。其中添加剂包含四种主要组分,各组分的含量都足以改进上述特性,并可能含有强化上述特性或给工作液提供更合乎需要的特性的其它组分。该添加剂必须包含一种钙盐、一种二硫代磷酸锌盐形式的耐极端压力-抗磨添加剂、一种含硼环氧化物和一种羧酸增溶剂。该羧酸增溶剂最好是含有一种具有12~500左右碳原子取代烃基-碱取代基的酰化剂的胺反应产物。关于添加剂和四种主要组分的特定用量和范围将叙述如下。可是由于许多不同类型的工作液都可以用这种添加剂,所以这些量可能有变化,而且由于其它组分及其用量,这些量也可能稍有变化。
本发明人发现,虽然有关这四种必要的主要组分每种的量和上面按种属描述的这四种组分的每个的准确定义,有某种灵活性,但是,如果完全不顾量的限制,或者任意地用其它组分代替这四种主要组分,那么就不能获得有用的工作液。
本发明的主要目的是提供一种具有各种不同工作特性的工作液,特别是当这种工作液用作拖拉机工作液的时候。
本发明的另一个目的是提供一种能够通过关于诸如耐极端压力/抗磨特性、容水性、制动器能力和震动以及过滤性之类特性的各种不同试验的工作液。
本发明的再一个目的是在不损害其他方面的工作性能的情况下,对已改进的低温流动性/过滤性、极压/抗磨性、摩擦改进性、湿制动器震动抑制性和有关推动液压、传动、动力转向和制动的能力等方面,同时提供改进的工作性能。
还有另外一个目的,是在对腐蚀试验和传动性能无不良影响的情况下,增进有关耐极端压力/抗磨特性的工作性能。
再一个目的,是在不限制耐极端压力性能的情况下,通过加入表面活性剂使溶水性得到改进。
本发明的其他目的包括提供一种工作液,该工作液能够通过有关摩擦性、低温流动性、密封溶胀性、抗泡沫性、抗氧化性、以及用螺旋伞齿轮和直齿正齿轮试验所显示的极端压力保护性等特性的许多不同试验。
另一个目的,是在提供足够的动力转向性能的同时,提供足够的以涡轮液压传动氧化试验法(Turbo    Hudra-matic    oxidation    testing)[通用汽车公司试验法(General    Motor    Corp.test)]所显示的传动性能。
另一个目的是提供一种工作液,该工作液可为动力变换传动离合器提供足够的摩擦保留,并提供腐蚀抑制,特别是有关黄色金属(即铜、黄铜、青铜)腐蚀,同时提供改进的耐极端压力性能,为湿制动震动器震动抑制提供适宜的摩擦性能,并同时提供湿制动器能力和动力输出离合器工作性能。
本发明的一个主要目的是提供一种工作液,该工作液包含它的一些主要组分,这样工作液就可同时提供各种所希望的特性。
熟悉本业务的人在阅读本说明之后,就会明白本发明的各种目的。
本发明可以工作液最终产品的形式生产和销售,它可以用于如拖拉机之类的各种机械设备。但是,本发明一般是以浓缩物的形式生产,然后将浓缩物稀释在大量的烃油中,配成最终的工作液。浓缩物本身是由各种组分制成的,各种组分本身往往是含在某些类型的油中,即稀释剂或“稀”油中。必须记住,工作液中所含各组分的重量百分数。上述含在工作液中各组分的重量百分数,是指有效化学物质的重量百分数,而不是可能与其“稀”油一起加入的那种组分。
本发明的工作液的四种主要组分是:(1)钙盐,(2)二硫代磷酸的Ⅱ族金属盐形成的抗磨添加剂,(3)含硼环氧化物,(4)羧酸增溶剂。现在详细介绍这四种组分的每一组分以及最好存在于本发明的工作液中的其它组分。应该指出,这些组分本身没有那一种本质上是新化合物。但是这些 化合物相互结合地存在,确可提供一种新的工作液,它提供了前所未有的改进性能。
过去曾公开过各种不同类型的金属盐,并指出由于其洗涤或分散性质,和能够中和在装有润滑油的发动机或设备的操作过程中在润滑油中生成的不良酸性物而特别有价值。这类金属盐,一般是具有高分子量脂肪羧酸、磺酸、酐、酯、酰胺、酰亚胺或盐的过碱化和(或)中性络合物的形式。这些过碱化络合物可用作润滑油、汽油或其它有机材料的添加剂。
在第3,714,042号美国专利中,已一般地公开了过碱化络合物。为了公开可能与本发明有关的钙盐和钙盐络合物,将此专利引用在这里作参考。本发明人发现,虽然许多其它类型的金属盐和金属盐络合物,一般都可用于本工艺,但是只有钙盐和钙盐络合物可以为本发明的工作液提供理想的特性。此外,现在还发现,最好包括以过碱化和(或)中性钙的磺酸盐、过碱化和(或)中性钙的磺酸盐-羧酸盐和过碱化钙的羧酸盐等形式的过碱化和(或)中性钙的络合物。
用在本发明工作液中的过碱化碳酸钙络合物的混合物,可以通过使油溶性磺酸(例如,组成石油磺酸酯和磺化烷基苯等类型的磺酸)单独或与钙的烷基酚盐、低级混合醇和过量的石灰合起来碳酸化制得。使用石灰使这种油可溶性磺酸或酚和钙的烷基酚盐过碱化,此时,过碱化碳酸钙络合物即可生成。本发明可以使用这种络合物。但是可能满意的是,使用经石灰过碱化,然后用聚异丁烯取代琥珀酸酐对络合物作后处理使其稳定的溶液。用在本发明中的过碱化钙络合物,可以与其它类似的化合物(例如,包括与钙酚盐结合的磺酸钙)结合使用。本发明的这种组分可能是含有中性和过碱化盐络合物的混合物。
所用“络合物”这一术语,是指金属含量超过中性或一般金属盐的金属含量的碱性金属盐。因此,表示络合物特性的“金属比”是,总金属当量与中性和一般金属盐中金属当量之比。络合物的“碱值”,是滴定法测 得的相当于一克络合物的KOH的毫克数。
本发明所用钙络合物的“碱值”变动于0到大约500TBN范围内。当这种络合物含在稀释油中时,钙络合物的碱值,较好的是在从200左右到400左右的范围内,更好的是300左右。
在本发明中,金属盐络合物必须包含一些钙金属盐络合物。但是,也能存在其他金属盐络合物以及可能存在未“过碱化”的钙盐。
本发明所用的有用钙络合物,可按下述方法制备:
取50克聚异丁烯(分子量1000)取代琥珀酸酐,加入950克的、碱性烷基苯磺酸(平均分子量为385)的碳酸钙盐的矿物油(碱值约为300,钙含量约为12.0%,硫含量约为1.4%)溶液,在25℃下后处理(皂化值为100)。混合物在55~57℃搅拌0.65小时,然后在152~153℃下0.5小时,在150℃下过滤。滤液的碱值约为300,含53%的矿物油。
适宜于用在本发明中的钙盐络合物,能有效地使分散性和防锈性等方面的性质得到改进,当用于拖拉机液压液时,其用量为液体重量的0.5~5.5%左右。
用在本发明中的耐极端压力-抗磨添加剂是二硫代磷酸锌的形式。虽然有极大量各种类型的抗磨添加剂可用于此类工作液,但是,本发明人发现,二硫代磷酸锌型抗磨添加剂,与其它组分合在一起,对得到所希望的性质起着特别好的作用。在第4,263,150号美国专利中,公开了特别有效的二硫代磷酸锌抗磨损添加剂,为了公开最佳的二硫代磷酸锌盐起见,将此专利引用在这里作参考。
据发现,经亚磷酸盐和(或)烯烃处理的二烷基二硫代磷酸盐,在本发明中,可以起特别好的作用。更具体地说,用亚磷酸三芳基酯,特别是用亚磷酸三苯基酯,处理这类盐或其酸的母体,得到的结果是这些盐使本发明的工作液,特别是拖拉机工作液,起到特别好的作用。这些锌盐或其 酸母体在经亚磷酸三芳基酯化合物处理之后,处理过的锌盐具有减轻沾污和腐蚀与本发明同时使用的金属部件的倾向。具体地说,这类处理过的锌盐或酸的母体不大可能沾污或腐蚀铜质部件。
众所周知,二烷基二硫代磷酸盐,用在润滑组合物中时,对它们的抗磨性是有用的。但是用在本发明中的抗磨添加剂已通过某些方法消除了这类锌盐的硫活性。一种除去硫活性的方法涉及用亚磷酸盐处理盐或其酸的母体。例如,对本发明有效的抗磨添加剂可按下法制备:
将二烷基二硫代磷酸锌或二烷基二硫代磷酸和羧酸的混合锌盐与亚磷酸三苯基酯一起加热。用在制备锌盐中的二烷基二硫代磷酸本身,是通过至少一种醇与含有超过化学计算量的硫的五硫代二磷反应而制得的。按足以改进工作液抗磨性的用量加入本发明的二硫代磷酸锌组分,当用于拖拉机工作液时,其量占工作液重量的1%左右到4%(重量)左右。
大家知道,各种含硼化合物对工作液是有用的。现已发现,含硼的环氧化物与上述其它组分结合,可发挥特别好的作用,从而提供具有改进特性的工作液。这类含硼的环氧化物,可通过使结构式如下的环氧化物:
Figure 87100657_IMG1
其中,R,R′,R2和R3为氢或C8~30的烃基,其中至少有一个是烃基,与硼酸,硼的氧化物或结构式为(RO)xB(OH)y的硼酸烷基酯(式中,x为1到3,y为0到2,x和y的和为3,R为含1到6个碳原子的烷基)反应而得,在第4,410,438号美国专利中公开了这类 含硼的环氧化合物,为了说明用在本工作液中含硼的环氧化物组分,引用此专利在这里作参考。
通过硼酸与具有约含16碳原子的环氧化物的1,2-环氧化物混合物反应,可获得一种最佳的含硼环氧化物。
将1,2-环氧化物十六烷与硼酸合在一起,可以制得对本发明有用的含硼环氧化物。在有水和甲苯存在下,将混合物加热到180℃左右。反应可以在有稀释油存在下进行。所得的产物是对本发明工作液有用的含硼环氧化合物。
含硼环氧化物的用量应足以使工作液能通过有关的工作液的试验,对于拖拉机工作液而言,其用量占工作液重量的0.1%(重量)左右到1.5%(重量)左右。
本工作液的第四个主要组分是羧酸增溶剂。这种组分能够以一种可提供微水粒乳状液的方式与其它组分相互作用,从而使容水性和过滤性得到改进。羧酸增溶剂组分的用量应足以使上述特性,即容水性和过滤性得到改进,对于拖拉机工作液而言,其用量占工作液重量的0.1%(重量)左右到1%(重量)左右。在第4,435,297号美国专利中公开了这类羧酸增溶剂的一些最佳例子,为了说明对本工作液有用的羧酸增溶剂,将其引用在这里作参考。
用在本工作液中的羧酸增溶剂是含氮的无磷羧酸衍生物。这类衍生物是通过酰化剂与链烷醇叔单胺的反应制得的。现已发现,有些特殊助溶剂在工作液中起特别好的作用,尤其是用作拖拉机工作液时。本发明人发现的最佳的羧酸增溶剂,是聚丁烯琥珀酸酐与N,N-二乙醇胺在摩尔比为1∶2下的反应产物。所得产物主要是酯盐,并含有少量的二酯。此外,此产物可能含有少量游离的未反应的聚丁烯和微量的与N,N-二乙醇胺起反应的马来酸酐。
最适用于本发明的羧酸增溶剂,是含氮无磷的羧酸衍生物,该衍生物 是羧酸酰化剂(A)与链烷醇叔单胺(B)在30℃左右到使一个或更多反应组分分解的温度范围内的反应而获得的。酰化剂(A)至少有一个含有20左右到500左右碳原子的烃取代基;单胺(B)有一个羟基和总数约达40的碳原子。
除上述四种主要组分之外,本发明的工作液最好还含一些粘度改进剂和消泡剂。各组分的类型和数量,根据诸如操作温度、所要求的粘度、液体经受搅拌的程度和所允许的泡沫量之类的因素予以调节。由于工作液可能要在宽温度范围下的设备中使用,所以非常需要加入粘度改进剂,以有助于工作液的粘度调节。粘度改进剂的含量一般占工作液重量的0.5%(重量)左右到8%(重量)左右。此外,由于此工作液一般要经受大量的机械搅拌和压力,所以非常希望包含一种消泡剂,以便降低和(或)消除起泡。起泡可能引起使用本发明工作液的设备的机械操作问题。消泡剂含量一般占工作液重量的0.005份左右(重量)到0.08份左右(重量)。
某些有用的粘度指数改进剂包括众所周知的聚甲基丙烯酸酯化合物、氢化苯乙烯-丁二烯粘度改进剂和苯乙烯-malan共聚物。一种有用的消泡剂包括90%(重量)左右煤油和10%(重量)左右硅氧烷剂(扩散常数200,25℃粘度30000c    St)两者的混合物。
本发明的工作液可以具有诸如液压/传动液、制动器液、动力转向液和拖拉机工作液之类的各种专门类型工作液的形式。这些工作液的精确组成可能稍有不同。熟悉此专业的人员,在阅读了本说明并考虑到工作液特性受所述各组分及其数量范围影响之后,就可以拟定出此类工作液的精确组成。为了得到本发明的最终产物,必须将四种主要成分加入烃油内。四种主要成分以有效化学物的形式存在于烃油中,其含量占本发明工作液总重量的0.5%(重量)左右到19.5%(重量)左右。因此,烃油的用量占工作液总重量的81.5%(重量)左右到99.5%(重量)左右。
本发明的四种主要组分可以是组分本身,或与其它组分在一起的浓缩物。浓缩物可以含1%(重量)左右到99%(重量)左右的有效化合物,其余为烃油。
当配制拖拉机工作液时,烃油的含量范围一般为81.5%(重量)左右到99.5%(重量)左右。拖拉机工作液各主要组分的含量如下:钙盐含量为0.5%(重量)左右到5.5%(重量)左右;耐极端压力/抗磨添加剂的含量为1%(重量)左右到4%(重量)左右;含硼环氧化物的含量为0.1%(重量)左右到1.5%(重量)左右;羧酸增溶剂的含量为0.1%(重量)左右到1%(重量)左右。上述所有的重量含量都是以在全部拖拉机工作液内的有效化合物的重量份为基础。
在本发明的一个最佳实施方案中,钙盐含量约为1.41%(重量),或带稀释油时约为3%。耐极端压力/抗磨添加剂的含量约为1.7%(重量);含硼环氧化物的含量约为0.5%(重量);羧酸增溶剂的含量约为0.25%(重量)。以上是按拖拉机工作液总量计算的有效化合物的量。
实例Ⅰ
一种溶于烃油的配方。该配方包含:2.82%(重量)的过碱化磺酸钙盐络合物;3.38%(重量)的二硫代磷酸锌;1%(重量)的含硼环氧化物;0.5%(重量)的羧酸增溶剂;1.93%(重量)的苯乙烯/马来酸酐粘度指数(Ⅵ)改进剂和0.02%(重量)的硅氧烷消泡剂。
实例Ⅱ
一种溶于烃油的配方。该配方包含:1.76%(重量)的过碱化磺酸钙盐络合物;2.14%(重量)的用亚磷酸三苯基酯处理过的二硫代磷酸锌;0.63%(重量)的含硼环氧化合物;0.31%(重量)的羧酸助溶剂作为基本组分,并包括1.93%(重量)的苯乙烯/马来酸酐粘度指数改进 剂和0.02%(重量)的硅氧烷消泡剂。
实例Ⅲ
一种溶于烃油的配方。该配方包含:1.41%(重量)的过碱化磺酸钙盐络合物、1.71%(重量)的烯烃处理过的二硫代磷酸锌、0.5%(重量)的含硼环氧化合物和0.25%(重量)羧酸助溶剂作为主要组分,并包括1.93%(重量)的苯乙烯/马来酸酐粘度指数改进剂和0.02%(重量)的硅氧烷消泡剂。
上述实例的每个例子的实际组分可能有些变化。例如,对于所用的过碱化磺酸钙盐络合物,实际采用的组分可以是一种用钙化合物过碱化,然后又经过分子量为700左右到5,000左右的聚丁烯琥珀酸或酐处理的磺酸钙盐络合物。对于二硫代磷酸锌,这种组分可以是用亚磷酸三苯酯处理过的二(2-乙基己基)二硫代磷酸锌盐和2-乙基己基羧酸的混合物。这种盐最好是混入超过化学计算量的锌,即这种盐是过锌化的,含有1.2左右到1.4左右的化学计算当量的锌。含硼环氧化物可以是通过硼酸与含16个碳原子1,2-环氧化物反应所得的产物。羧酸增溶剂可以是通过聚丁烯琥珀酸酐与N,N-二乙醇胺在摩尔比约为1∶2下反应所得的产物。此外,这些配方按照其所希望的最终用途可以包括其它组分。熟悉本专业的人,将根据准备要生产的工作液的具体要求,选择用作主要组分的每种实际专用化合物,其用量以及其它额外的有效化合物。一般熟悉本专业的人员,在考虑了它们的需要和阅读了本说明之后,就可以推断出化学组分的用量和实际特殊类型方面的变化。
本文已公开并描述了据认为是最佳的具体方案。不过考虑到了,熟悉本专业的人在阅读了本说明之后,便可识别某些被认为是包含在本发明范围之内的变化。
