Description

用于冷轧铝的冷却润滑剂
技术领域
本发明涉及一种用于冷轧铝的冷却润滑剂(轧制油)，一种用于生产铝产品的方法，该铝产品没有由脂肪酸引起的视觉上可见的缺陷图案，以及涉及冷却润滑剂用于轧制铝的应用。
背景技术
在用于生产铝带和铝箔的方法中，轧制乳液和轧制油被用作冷却润滑剂，其对生产的经济可行性和产品的质量有很大影响。在轧制过程中，工作辊和被轧物品之间的摩擦值不应过高或过低。低的摩擦值可以改善轧制间隙的润滑，从而减少轧制过程中的能源消耗、摩擦热和轧辊磨损。
铝带和铝箔一般在两级轧制方法中通过轧制生产。为了生产铝带或铝箔，首先将铝锭在所谓的热轧机架中在多次过程(道次)中轧制成板坯或带材。随后再将其冷轧成更薄的带材或箔材。此外，带材或箔材还可以经过进一步的已知处理方法(退火、热或化学脱脂)。
在热轧过程中，通常使用轧制乳液(O/W)作为冷却润滑剂，而在冷轧过程中使用轧制油作为冷却润滑剂。在热轧的方法步骤中，铝锭被大幅成型以形成铝带。在冷轧机架中，烃基轧制油被用作冷却润滑剂。润滑添加剂可以被添加到这些轧制油中。典型的润滑添加剂例如是脂肪醇、脂肪酸和脂肪酸酯。
使用脂肪酸的缺点是，通常使用的脂肪酸，如月桂酸、肉豆蔻酸、棕榈酸或硬脂酸，在温度低于40℃时以固体形式存在，只有在温度明显高于300℃时才会蒸发。因此，在挥发性较强的轧制油蒸发后，在没有被轧制油持续冲洗的辊轧机架部件上会出现脂肪酸的固体或糊状沉淀物以及由此形成的金属皂。当这些固体或糊状沉淀物从辊轧机架或管道上脱落并到达铝带或铝箔上时，在轧制物上就会出现视觉上可见的缺陷图案，这些缺陷无法再通过后续工艺步骤(进一步的轧制道次、辊式切割、热或化学脱脂)去除。
脂肪酸作为润滑添加剂的另一个缺点是，它可以与轧制物的成分发生反应，尤其是与成型过程中形成的轧制磨料发生反应。在这种情况下，会形成金属皂，主要是铝皂。脂肪醇在醇氧化形成酸之后也能与铝磨料反应形成铝皂。
由所使用的脂肪酸和铝磨料形成的铝皂在冷轧油中只有有限的低溶解度。此外，它们与铝磨料颗粒形成团块。这些溶解性差的金属皂和金属皂/金属磨料结块会沉积在冷轧机架的部件上，并会在管道和油箱中形成上述沉积物。
如果这种金属皂或金属皂/金属磨料结块从轧机、冷轧机的部件或从管壁上脱落，并到达铝带或铝箔上，在轧制物上也会出现视觉上可见的缺陷图案，这些缺陷无法再通过随后的制造铝带或铝箔的工艺步骤来去除。为了避免这种表面缺陷，已知的是，通过过滤或蒸馏方法将金属皂和金属磨料从冷轧油中分离。为此，可以使用过滤器，如水平压板过滤器和助滤剂，如硅藻土、珍珠岩和漂白土。通过增加使用漂白土助滤剂，可以抑制轧制油中不断增加的皂含量。然而，由此缩短了过滤的时间，并且所需的助滤剂量和产生的过滤废物量都增加了。
EP 3 124 583 A1说明了一种水溶性金属加工液，其包含具有硫化物结构的二羧酸、聚亚烷基二醇、多元醇/聚亚烷基氧化物加合物和单羧酸。因此，说明了一种水溶性的、而不是基于矿物油的组合物。
EP 0 484 542 A1说明了一种用于金属加工的润滑剂，其除了矿物油和直链烯烃之外，还含有脂肪醇或脂肪酸。此外，其中所述的润滑剂中还可能含有乙二醇。该文献的示例组合物中不含乙二醇。润滑剂中的烯烃的缺点是，在铝带退火后，它们会导致铝板上的高退火残留。
EP 3 124 583 A1说明了一种水溶性金属处理剂，其除了脂肪酸和脂肪醇之外，还可以含有聚亚烷基二醇。
因此，需要有新的润滑添加剂，其不会与铝磨料形成反应产物，也不会与轧制油的其他成分发生反应。
发明内容
本发明的目的在于提供一种冷却润滑剂，通过这种冷却润滑剂可以避免在铝带或铝箔上出现常常在冷轧方法中由脂肪酸和/或脂肪醇引起的视觉上可见的缺陷图案，而不会损害轧制油的润滑效果和摩擦学活性。
这一目的通过一种用于冷轧铝的矿物油基冷却润滑剂(轧制油)
实现。其含有
-矿物油基的或合成的基础油，
-聚亚烷基二醇或含有聚亚烷基氧化物结构的化合物，其中
-该冷却润滑剂基本上不含脂肪酸和脂肪醇。
本发明进一步涉及一种用于生产铝制品(铝带或铝箔)的方法，其中上述冷却润滑剂被用于冷轧铝带。
最后，本发明还涉及上述冷却润滑剂用于将铝带冷轧成比尚未冷轧的铝带更薄的铝带或铝箔(铝制品)的应用。
得到的铝制品没有由脂肪酸和脂肪醇引起的视觉上可见的缺陷图案。令人惊讶地，其对水和N-甲基-2-吡咯烷酮(NMP)具有高润湿性。此外，如果希望铝箔表面具有高的表面能，该铝制品不需要任何电晕处理。
根据本发明的冷却润滑剂是油溶性的；它不能与水混溶。根据本发明的冷却润滑剂不含直链烯烃，尤其是不含具有6至40个碳原子的α-烯烃。
在本发明的意义中，基本不含脂肪酸是指脂肪酸作为润滑添加剂，基于冷却润滑剂的质量以最高0.2重量％，优选最高0.1重量％的比例包含在其中。在本发明的意义中，基本不含脂肪醇是指脂肪醇作为润滑添加剂，基于冷却润滑剂的质量以最高0.4重量％，优选最高0.3重量％的比例包含在其中。如果根据本发明的润滑剂中的脂肪酸含量和/或脂肪醇含量高于上述规定的最大值，则用其轧制的铝制品的润湿性能会变差。
本发明意义上的铝制品是指经过冷轧的铝板、铝带和铝箔。例如，铝箔可以有4至100μm的厚度，或者比100μm更厚。在本发明的意义中，铝这一概念包括铝和铝合金。
根据本发明待使用的聚亚烷基二醇包括常见的聚亚烷基二醇和具有聚亚烷基二醇结构的化合物，如聚氧乙烯脂肪醇醚(乙氧基化脂肪醇)。聚亚烷基二醇或聚亚烷基氧化物中的亚烷基可以是乙烯、丙烯或丁烯(聚乙二醇、聚丙二醇、聚丁二醇)。脂肪醇可以包括8至20个碳原子。脂肪醇基例如可以是癸醇、月桂醇、肉豆蔻醇、十六烷醇或硬脂醇。这些化合物在铝的冷轧过程中具有润滑和冷却特性。下面使用的术语聚亚烷基二醇包括聚亚烷基二醇和具有聚亚烷基二醇结构的化合物。
根据本发明使用的聚亚烷基二醇在40℃时可以具有5mm2/s至250mm2/s，优选10mm2/s至200mm2/s的运动粘度。根据本发明使用的聚亚烷基二醇在5℃以上以液体形式存在，因此易于计量进料。它们可以不溶于水或可以溶于水。
特别优选的是，使用乙氧基化脂肪醇，例如四乙二醇单十二烷基醚，作为聚亚烷基二醇或含有聚亚烷基氧化物的化合物。相应的聚亚烷基二醇可以在市场上买到。
聚亚烷基二醇在根据本发明的轧制油中的比例最高为10重量％，尤其0.01至8重量％，特别优选0.1至5重量％，分别基于轧制油的质量。因此，聚亚烷基二醇取代了通常存在于冷轧润滑剂中的添加剂脂肪酸和脂肪醇。根据本发明的冷却润滑剂具有良好的润滑效果或摩擦学效果，而没有前述脂肪酸和脂肪醇的不利影响。
根据本发明的冷却润滑剂基于烃基础油，其沸点在180℃至300℃范围内，根据DINEN ISO 3405测量。该基础油含有直链烃和支链烃。该基础油可以包括烃混合物。基于基础油的质量而言，其中的芳烃比例优选低于1重量％。基础油可以是矿物油或合成油。它可以含有天然的和/或合成的正石蜡和/或天然的和/或合成的异石蜡。
这种低芳烃混合物的运动粘度在20℃时可以为1.5至3.6mm2/s。这种运动粘度提供了在冷轧机架中良好的流动特性，并能实现均匀润滑和冷却。基础油在根据本发明的冷却润滑剂中基于冷却润滑剂质量的比例可以占到90重量％及以上。基础油的比例例如可以占冷却润滑剂质量的90重量％至99重量％。
根据本发明的冷却润滑剂可以包括用于提高高压润滑性能的常见添加剂、抗氧化剂和传导性改进剂。
用于提高高压润滑性能的添加剂包括直链饱和C10-14羧酸的酯。例如，这些包括硬脂酸丁酯和十二酸甲酯。十二酸甲酯是特别优选的。基于冷却润滑剂的质量，这些物质的含量可最高达10重量％，优选是1至8重量％。
合适的抗氧化剂包括立体阻碍的一价、二价和三价苯酚以及多核苯酚，特别是叔丁基苯酚。该组的典型代表是亚甲基-4,4'-双-(2,6-二叔丁基苯酚)。进一步合适的抗氧化剂包括胺类，如二苯胺、苯基-α-萘胺、p,p′-四甲基二胺二苯基甲烷和N,N′-二苯基对苯二胺。上述抗氧化剂可以与进一步的抗氧化剂如硫化物和聚二硫化物以惯常的浓度结合使用。
根据本发明的冷却润滑剂可以对冷轧后得到的铝制品进行进一步加工来用于一系列的应用，而不需要进行电晕处理。然而，在铝制品的表面实现了如在电晕处理后在存在脂肪酸和脂肪醇的情况下进行冷轧的铝制品上得到的表面能。此外，铝产品的表面对水和N-甲基-2-吡咯烷酮(NMP)具有很高的润湿性。
铝制品在其表面上含有在根据本发明的冷却润滑剂中使用的聚亚烷基二醇的残留物。冷轧后铝制品上的聚亚烷基二醇的量可以达到5mg/m2或更多。在执行根据本发明的方法后，在铝制品的表面例如可以存在0.01mg/m2至5mg/m2的聚亚烷基二醇或含有聚亚烷基氧化物结构的化合物。
已经发现，通过根据本发明的润滑剂，还可以大大减少所生产的铝带或铝箔上视觉可见的缺陷图案的数量。这可能是由于轧制油成分不会在轧制物上形成难以清除的沉积物。脂肪醇的舍弃似乎会加强这种减少。根据本发明的轧制油的残留物可以很容易地以化学或热方式从轧制物表面去除，或者在热脱脂后，轧制物表面只有轻微的残留物形成。
有利的是，根据本发明的冷却润滑剂在其使用前加热到至少约40℃。这样可以降低其粘度，使其更快地流过轧辊间隙。
下面的例子用来进一步解释本发明。
具体实施方式
实施例1--各种润滑剂的摩擦系数的确定
根据本发明的冷却润滑剂的润滑性能是用PCS仪器公司的MTM2迷你牵引机在标准配置下，利用施加负载的钢球(直径19.05mm)和可在不同速度下旋转的铝制测试盘测定的。通过钢球(3/4"球轴承钢AISI 52100(100Cr6，1.3505))对测试盘的负载被设定为40N(0.5GPa接触压力)，以及在不同的滚动速度下的摩擦系数(RK)。在1到200m/min的轧制速度下测得的摩擦系数的两个平均值(MW)显示在下面的表1中。盘是由铝合金AA1XXX形成的。试验期间的滑动/滚动比率(SRR)为50％。在摩擦测试之后，测试了铝制测试盘对水的润湿性。为此，在盘上在运行轨迹旁边用去离子水进行了滴液试验，滴液量为5μl。标准化的测试程序与内部工作指示“Hydro CO
0620”一致。运动粘度是根据DIN 51562标准在40℃测量的。

***在各自情况下：聚(丙二醇)单丁醚，40℃时的运动粘度为33、57和77mm2/s
****聚丙二醇的混合物，40℃时的运动粘度为75和225mm2/s，40℃时混合物的粘度为175mm2/s。
单用基础油形成润滑膜是次优的；有金属皂形成。润滑剂试样2提供了良好的润滑膜，有更多的磨损，但盘面干净。根据本发明的润滑剂试样3提供了更好的润滑膜形成。这同样适用于试样4，而且其在球上几乎没有显示出运行轨迹。这也适用于试样5，其几乎没有出现任何磨损。试样6至12显示了良好的润滑膜形成。试样6和7有轻微的磨损，试样8几乎没有任何磨损。试样6显示出可接受的水润湿性，试样7显示出良好的水润湿性，试样8显示出非常好的水润湿性。试样10几乎没有任何磨损，球上几乎没有任何运行轨迹。试样11和12在球上的运行轨迹很轻微。
实施例2--用不同的润滑剂冷轧后的润湿角的确定
在下面的实验中，也是用AA1XXX型合金的铝箔来确定铝箔表面的润湿角。测量用水和NMP润湿时的接触角(KW)。润湿角或接触角是用德国汉堡Krüss GmbH公司的DropShape Analyzer DSA 10以5μl去离子水或NMP在滴液试验中测定的。测量结果是在铝箔试样表面的四个不同位置的单独测量的平均值。测量结果显示在下面的表2中。此外，表面能(SFE)是通过确定接触角来测定的。相应的数值在表2中给出。

**聚丙二醇单丁醚
表2中显示的结果表明，带有含聚亚烷基氧化物结构的化合物的润滑剂导致铝产品的至少针对NMP而言的接触角明显更低。这对特定应用是有帮助的。
