Abstract
本发明公开了功能流体用腐蚀保护剂,其包含5-80重量%的基于具有10-20个碳原子的饱和或不饱和脂肪酸的至少一种脂肪酸烷醇酰胺、5-80重量%的具有2-14个碳原子的至少一种醇、和5-80重量%的具有10-12个碳原子的至少一种芳族单羧酸或脂族二羧酸,其中这些组分的总和为100重量%,和所述重量%相对于所述腐蚀保护剂的重量;水基功能流体用的含有所述腐蚀保护剂的水溶性浓缩物;以及其用于制备金属成形和金属切削用的冷却/润滑剂、研磨剂、液压油和润滑剂的用途。
Description
本发明包括功能流体用腐蚀保护剂、用于含水功能流体的包含该腐蚀保护剂的水溶性浓缩物、以及其用途。
含水功能流体由于其低可燃性和低环境风险而受到增大的关注。这些功能流体是用作金属成形和金属切削用冷却/润滑剂、研磨剂、润滑剂的流体,以及特别地用作压力流体,即液压油(Hydraulikflüssigkeiten)。这些含水功能流体也称为HFA流体或HFA液压油。该HFA液压油特别地用于矿业中的液压工作面支护系统。它们通过混合1-20重量%的包含必要有效成分之一的含水浓缩物和辅助的99-80重量%的水而现场制成。所述浓缩物可包含作为润滑剂的合成制品或基于矿物油的制品。取决于所述水溶性浓缩物的组成,HFA液压油为包括微乳液在内的与矿物油或合成油的乳液(HFAE)或者溶液(HFAS)。该HFA液压油具有水的粘度,并可用于+5℃至+55℃的温度范围内。
当该类型含水功能流体或HFA液压油不能提供充分的防腐作用时,这会导致与所述功能流体相接触的表面即液压系统的腐蚀。特别地,该腐蚀可引起剥蚀、空穴、凹坑形成,以及甚至引起结垢腐蚀产物的沉淀。由于当将HFA液压油用于大型液压系统如矿业中的工作面支护时,必须不惜任何代价来避免该类腐蚀,因而这些含水功能流体包含腐蚀保护剂及其它添加剂,如动物油、植物油、矿物油和/或合成油、脂肪、或者油组分或脂肪组分作为润滑剂、脂肪醇、杀生物剂、杀菌剂、络合剂、重金属抑制剂、非离子或阴离子乳化剂、分散剂和消泡剂。
从EP 1175489 A1中,我们得知用于制备包含油相、水相、杀细菌剂或杀真菌剂和高压组分的含水切削液的方法。这些切削液可包含有机酸如癸二酸。
从DE 19833894 A1中,我们得知包含天然或合成矿物油、乳化剂、溶剂、防腐剂、金属抑制剂及其它典型添加剂和具有小于7.7的pH以确保皮肤耐受性的水溶性冷却-润滑浓缩物。作为腐蚀保护剂,该浓缩物可包含硼酸与伯或叔烷醇胺、乙氧基化或丙氧基化脂肪酸或脂肪酸烷醇酰胺、磷酸酯、三唑或噻二唑中的单独一种或相互组合的反应产物。尽管该文献提及可使用具有pH值接近中性的该浓缩物制备含水冷却/润滑剂,以及提及没有导致用所述冷却/润滑剂的水溶液处理的金属部件的腐蚀,但是由其制成的这些浓缩物和所述功能流体并不具有令人满意的腐蚀保护效果。特别地,当这些含水冷却/润滑剂与金属表面长时间接触时它们会导致被暴露的金属表面的腐蚀,如在液压系统中的情况,即通过不希望的结垢沉淀和剥蚀。
因此本发明的目的是提供功能流体用腐蚀保护剂,其中在不降低该流体的根据其他要求的性能的情况下所述HFA流体(即用于液压系统的HFA液压油)的腐蚀保护性能得以改进,因此其可以用于大体积的极其昂贵的液压系统中,如用于矿业中。
令人惊讶地,已经发现通过本身分别已知的至少三种不同腐蚀保护添加剂的组合,将所述HFA液压油的腐蚀保护性能提高至出乎意料的高水平,因此不但可以防止剥蚀、空穴和凹坑形成,而且可以完全避免结垢腐蚀产物的沉淀,这可以在根据DSK Norm N 762830的缝隙腐蚀测试中使用典型HFA流体而观察到,如下文所述。
因此本发明的目的是根据主权利要求的腐蚀保护剂。从属权利要求涉及本发明该目的的优选实施方式、包含该腐蚀保护剂的水溶性浓缩物和其用于制备金属成形和切削用的含水的冷却/润滑剂、研磨剂、液压油或润滑剂的用途。
因此本发明的一个实施方式是功能流体用腐蚀保护剂,其包含5-80重量%的基于具有10-20个碳原子的饱和或不饱和脂肪酸的至少一种脂肪酸烷醇酰胺、5-80重量%的具有2-14个碳原子的至少一种醇和5-80重量%的具有10-12个碳原子的至少一种芳族单羧酸或脂族二羧酸,其中这些组分的总和为100重量%,以及所述重量百分数相对于所述腐蚀保护剂的重量。
在下面实施例和对比实施例中解释的比较实验已显示只有当所述腐蚀保护剂包含所述三种必需组分,和所述芳族单羧酸或脂族二羧酸总共具有包括羧基在内的10-12个碳原子时,才能完全避免不希望的腐蚀。例如,当存在具有10个碳原子的脂族单羧酸如新癸酸时,则不能避免固体沉淀物和线状腐蚀的出现。从本领域技术人员的角度考虑,该结果无疑是令人惊讶和出乎意料的。
优选地,根据本发明的所述腐蚀保护剂包含25-60重量%的所述至少一种脂肪酸烷醇酰胺、15-25重量%的所述至少一种醇、和20-50重量%的上文定义类型的至少一种芳族单羧酸或脂族二羧酸。
在根据本发明的所述腐蚀保护剂中的所述脂肪酸烷醇酰胺优选基于具有12-18个碳原子的饱和或不饱和脂肪酸,和具有2-6个碳原子的烷醇胺,即单乙醇胺、二乙醇胺、三乙醇胺、单丙醇胺、单异丙醇胺、2-氨基-2-甲基-1-丙醇、2-氨基-2-乙基-1,3-丙二醇和/或二甘醇胺,所述二甘醇胺也称为2-氨基乙氧基乙醇或乙二醇-2-氨基乙基醚。

以下实施例用来进一步阐明本发明。
在实施例和对比实施例中,使用根据DSK norm N 762 830的缝隙腐蚀测试,测定由根据本发明的所述腐蚀保护剂而得到的腐蚀保护效果。在Glückauf 138(2002)No.5,208-212页中公开了使用所述缝隙腐蚀测试的腐蚀测试方法。所述方法包括将在纯静态条件下于95%湿度和35℃的测试温度将待测试的所述压力流体或液压油保持在规定冲压装置(活塞-汽缸)中达21天。在所述汽缸的内表面和所述活塞上的青铜部分之间形成缝隙区域。将典型密封环放于所述青铜部分上。在与处于测试中的所述流体接触21天后,拆卸所述冲压装置并检查所述汽缸的内表面上的缝隙区域的腐蚀状况。该缝隙腐蚀测试显示如果不存在足够的腐蚀保护作用,除了剥蚀和凹坑形成外,在所述汽缸表面上的缝隙区域中还沉积了鳞片状颜色相当不同的腐蚀产物。如果这些沉积物位于在所述汽缸表面上的密封环的缝隙区域中,则通常还在所述密封环表面和所述青铜表面上发现这些沉积物。小颗粒尤其聚集在密封唇上,这些小颗粒是导致围绕所述汽缸表面周边的线状腐蚀的原因。关于术语“缝隙腐蚀”的定义,参考标准DIN EN ISO8044-3.17。
实施例1-5和对比实施例A-E
首先使用列于下表1-3中的组分来制备水溶性浓缩物,然后以2重量份浓缩物与98重量份水的比例进行混合以制备HFA液压油,然后使用如上所述的缝隙腐蚀测试对其进行测试。
为了制备所述水溶性浓缩物,首先提供水,向其中加入氢氧化钾并通过搅拌使其溶解。加入在每种情况中使用的酸如癸二酸、十二烷二酸、十一烷二酸,或在对比实施例E中使用的新癸酸,并在50℃下进行搅拌直至该混合物的pH值为7。然后加入柠檬酸钠和单乙醇胺,并在搅拌下将所述混合物冷却到25℃。
在分开的容器中,加热作为润滑剂的一部分脂族烃(50%),然后在搅拌下加入脂肪酸烷醇酰胺、石油磺酸钠(Natriumpetrolsulfonat),并然后加入余下的脂族烃,随后加入其余成分。然后彻底混合和将从第一阶段得到的含水混合物在搅拌下加入到所述脂族烃混合物中。所得产物是淡褐色、澄清、略有粘性的浓缩物,然后将其与水进行混合以制备包含2重量%所述浓缩物和98重量%水的所述含水功能流体(HFA液压油)。将该HFA液压油置于用于所述缝隙腐蚀测试的冲压装置的缝隙区域中并在95%的湿度和35℃的温度下静置保存21天。在打开所述冲压装置并移出其中包含的所述HFA流体后,检查测试固定物的在外管底部上、在所述缝隙区域中和在所述青铜活塞区域中的淤积,和检查在内管和外管中进行清洁前的沉积物,和检查在所述内管和外管中进行清洁后的锈蚀,和检查在所述汽缸内表面上和在所述汽缸的缝隙区域中以及在所述青铜活塞表面上的固体沉积物。
如下表1-3中所显示,使用根据本发明的所述HFA液压油时不存在腐蚀效应,而对比实施例A和B中的产物不能通过根据DSN norm N 762 830的腐蚀测试,因为在清洁前可在汽缸上发现沉积物、以及在所述汽缸的缝隙区域中发现固体沉积物和围绕所述汽缸的缝隙区域周边发现线状腐蚀。
