Abstract
用于后处理阳极化铝及铝合金的组合物和使用所述的组合物提高阳极化铝及其合金耐腐蚀性、磨损和粘合性能的方法。该组合物包含pH约为2.5至4.5的酸性水溶液，该溶液含有有效量的三价铬盐、碱金属六氟锆酸盐，一种碱金属氟化合物例如氟硼酸盐和/或氟硅酸盐，以及有效量的水溶性增稠剂及表面活性剂。
Description
发明背景
发明领域
本发明涉及一种后处理阳极化铝的方法，以及涉及一种用于处理阳极化铝以提高粘合、耐磨损和耐腐蚀性能的组合物。更具体而言，本发明涉及一种新型组合物和涉及使用该组合物密封或者后处理阳极化铝和阳极化铝合金的方法。三价铬后处理(TCP)组合物包含酸性水溶液，该溶液含有有效量的至少一种水溶性三价铬盐、碱金属六氟锆酸盐，至少一种碱金属四氟硼酸盐和/或六氟硅酸盐，以及有效量的水溶性增稠剂和/或水溶性表面活性剂。
现有技术描述
阳极化铝在阳极化之后，通常由采用各种密封组合物的方法密封或后处理。目前阳极化铝的高性能的后处理或密封剂是以六价铬化学为基础的。六价铬具有剧毒并且是一种已知的致癌物质。作为结果，用于使这些保护性涂层沉积的溶液和涂层本身是有毒的。但是，这些薄膜产生对阳极化铝有显著的涂料粘合力、耐磨损和耐腐蚀性。典型地，在升高的温度下，密封涂层被沉积在阳极化涂层上并且通常通过浸渍或喷淋方法涂布。后处理通常通过军用的或商用的规范完成，所述的规范控制每一种被处理的涂层。如此，不存在像对于“转化涂层”铝一样，对所有的阳极化铝没有唯一的“后处理”规范。
此外，环境法、行政法规和地方职业、安全和健康(OSH)法规正推进军事和商业用户寻找无六价铬的后处理。在阳极化铝的情况下，阳极化薄膜和基质金属是相对无毒的。由于需要的六价铬后处理的加入，这些涂层变得有毒性。其他的后处理，如乙酸镍，和各种氟化物化合物不含有铬酸盐，但是它们的技术性能低于铬酸盐基涂层。此外，铬酸盐后处理的使用因为法规严格正变得更加昂贵。由于未来美国EPA强加的约束，费用可能是非常昂贵的。因而，虽然现有的铬酸盐后处理在它们的技术性能方面是显著的，原因在于它们在低应用成本下提供了增强的防腐蚀和粘合如涂料和其他涂层，但从生命周期费用、环境和OSH方面考虑，六价铬涂层对人和环境是有害的。
发明概述
本发明涉及一种新型组合物和涉及在环境温度或更高，例如高达约200°F的温度下，将所述组合物用于后处理或密封阳极化铝及其合金的方法。更具体而言，本发明涉及一种用于后处理阳极化铝及其合金以提高耐腐蚀性和粘合性能如涂料粘合力等的组合物。三价铬后处理(TCP)组合物包括一种pH约2.5至4.5，并且优选为3.7至4.0的酸性水溶液，并且每升所述的溶液，含有约0.01至22克的水溶性三价铬盐，约0.01至12克的碱金属六氟锆酸盐，约0.01至12克的至少一种选自碱金属四氟硼酸盐、碱金属六氟硅酸盐及其各种组合中的氟化合物，约0至10克且优选为0至2.0克至少一种水溶性增稠剂，和0至10并且优选为0至10克至少一种水溶性非离子、阳离子或阴离子的表面活性剂。
因此，本发明的一个目的在于提供一种用于后处理阳极化铝及其合金以提高粘合力、耐磨损和耐腐蚀的特性的水溶液，所述的水溶液包含三价铬盐、碱金属六氟锆酸盐和四氟硼酸盐和/或六氟硅酸盐。
本发明的另一个目的在于提供一种用于处理或密封阳极化铝及其阳极化合金的pH约为2.5至4.5、含有三价铬盐的稳定酸性水溶液。
本发明的再一个目的在于提供一种在约室温下，用于处理或密封阳极化铝及其合金的pH约为3.7至4.0、含有三价铬的稳定酸性水溶液，其中所述的溶液基本上不含六阶铬。
通过结合附图1-6(照片)时参考发明详述，本发明的这些和其他目的变得更明显。

发明详述
更具体而言，本方面涉及pH约为2.5至4.5，并且优选约为3.7至4.0的酸性水溶液，并且涉及所述的溶液在后处理或密封阳极化铝及其合金以提高阳极化铝的粘合和耐腐蚀性能中的应用。本发明的新型组合物包含：按每升溶液计，约0.01至22克且优选约4.0至8.0克例如6.0克的至少一种水溶性三价铬盐例如硫酸铬，约0.01至12克且优选约6至10克例如8.0克的至少一种碱金属六氟锆酸盐，约0.01至12克且优选约0.12至1.2克例如0.24至0.36克的至少一种选自碱金属四氟硼酸盐、碱金属六氟硅酸盐及其各种混合物或组合中的氟化合物。
在某些方法中，根据阳极化铝的物理特性，例如阳极化基材的实际尺寸，唯一的特征在于向溶液中加入增稠剂，其通过减缓溶液的蒸发而有助于在喷淋和擦抹涂布(wipe-on)期间形成最适宜的薄膜。它还减轻降低涂料粘合力的粉末状沉积物的形成。此外，增稠剂的加入有助于在大面积涂布过程中形成适宜的薄膜，并且减轻在由前面的步骤加工期间在基材上残留的漂洗水的稀释作用。此特征得到没有条纹缺陷并且更好着色和防腐蚀的薄膜。
在酸性水溶液中存在水溶性增稠剂如纤维素化合物，每升水溶液其量约为0至10克，优选为0至2.0克，且更优选为0.5至1.5克，例如约1.0克。根据阳极化铝的特性，可以向酸性水溶液中加入有效但少量的至少一种水溶性表面活性剂，每升酸性溶液其量约为0至10克，优选为0至2.0克，且更优选为0.5至1.5克，例如约1.0克。这些表面活性剂在现有技术中是已知的，并且选自非离子、阳离子和阴离子表面活性剂。
三价铬是作为水溶性三价铬化合物，优选作为三价铬盐加入的。具体而言，在配制本发明的酸性水溶液中，可以方便地向溶液中以其水溶性形式加入铬盐，其中铬的化合价为正3价。将优选的铬化合物以Cr2(SO4)3，(NH4)Cr(SO4)2或KCr(SO4)2和这些化合物的任何混合物的形式结合于溶液中。铝基材是纯的阳极化铝或含有60重量％以上的铝的阳极化铝合金。优选三价铬的浓度在每升水溶液中约4至8克或6.0克的范围内。已经发现当三价铬化合物以该优选范围存在于溶液中时，对于这些方法得到特别好的结果。优选以每升溶液约6至10克或8.0克的量向溶液中加入优选的金属氟锆酸盐。可以在包括溶液的温度例如温度高达约200°F或在环境温度的低温下进行阳极化铝的后处理。优选室温，原因在于它取消了加热装置的必要性。通过本领域已知的任何方法，例如烘炉干燥，强制通风干燥，红外灯照射等方法空气干燥涂层。对本发明而言，术语阳极化铝和阳极化铝合金包括由本领域已知的方法阳极化的铝及其合金。
下面的实施例举例说明本发明的酸性溶液和使用所述的溶液后处理或密封阳极化铝和铝合金的方法。
实施例1
用于后处理阳极化铝和铝合金以提高耐腐蚀性和粘合力的pH约为3.7至4.0的酸性水溶液包含：每升溶液约6.0克的三价铬硫酸盐，每升溶液约8.0克的六氟锆酸钾，每升约0.01克的四氟硼酸钾和每升约1.0克的纤维素增稠剂及每升溶液约1.0克的水溶性非离子表面活性剂。
实施例2
用于后处理铝及其合金以提高粘合力和耐腐蚀性的pH为3.7至4.0的酸性水溶液，其包含：按每升溶液计，约0.01至22克的三价铬硫酸盐，约0.01至12克的六氟锆酸钾，约0.01至12克的四氟硼酸钾和约0.5至1.5克的甲基纤维素增稠剂。
实施例3
用于后处理阳极化铝及其合金以提高粘合力和耐腐蚀性的pH为3.7至4.0的酸性水溶液，其包含：按每升溶液计，约4.0至8.0克的三价的钾-铬硫酸盐(KCr(SO4)2)，约6至10克的六氟锆酸钾，约0.01至12克的六氟硅酸钾和约0.5至1.5克的甲基纤维素增稠剂。
实施例4
一种制备酸性水溶液的优选方法包含在蒸馏水或去离子水中，混合约0.01至22克每升溶液且优选约6.0克每升的铬III的硫酸盐与约0.01至12克每升溶液且优选约8.0克每升的六氟锆酸钾。在静置24小时之后，最优选在溶液的pH上升为3.7至4.0之后，该组合物随时可以使用。对于最佳性能，使用约0.1重量百分比或约1.0克每升的Methocel F4M。四氟硼酸钾和/或六氟硅酸钾的加入量为每升0.01克直至它们的溶度极限。优选基于氟锆酸盐的重量，加入约50重量％的氟硅酸盐。基于氟锆酸盐的量，加入约1.0至10重量百分比的氟硼酸盐。更优选基于溶液中氟锆酸盐的量，加入约3.0重量百分比的四氟硼酸钾。
在本发明方法中，可以通过控制pH来使上面所述的溶液稳定。例如，将新制备的约8.0克每升的六氟锆酸钾和6.0克每升的铬III硫酸盐的溶液加入到稀硫酸中，以降低pH至约3.0。约1周后，pH上升至约3.6，此时没有进一步化学控制的条件下它稳定。可以通过酸或碱的加入调节pH，以保持组合物处于涂布沉积的最佳pH范围。
对于本发明而言，将后处理涂层如下涂布于阳极化铝基材。使用三种类型标准的阳极化方法。所有的类型由MIL-A-8625F详细说明。它们的常用名称为“第II类硫酸阳极化”、“硼酸硫酸阳极化”和“薄膜硫酸阳极化”。第II类阳极化方法通常用于各种其中疲劳性能不是关键的航空航天和其它基材上。薄膜硫酸和硼酸-硫酸方法作为备选方案用于铬酸阳极化。这些阳极化方法提供(rovide)更薄的膜并且特别用于铝基材的疲劳性能是重要的情况。
对于最佳耐腐蚀性能，所有的阳极化铝涂层要求后处理或密封剂，其典型基于用于最佳性能的六价铬。此外，这些后处理典型地作为溶液在升高的温度下，接近于水的沸点应用，以适宜地形成所需要的涂层。例如，在上面所述的薄膜硫酸和硼酸-硫酸阳极化中，在阳极化2024-T3铝合金的3″×10″×0.32″的铝面板之后，立即在去离子水中将面板完全漂洗两次。漂洗之后，在环境条件下立即将面板浸渍于实施例4所示的存放了6月的9加仑溶液中约20分钟。浸渍之后，立即进行两次去离子水漂洗。在通过ASTM B 117进行1000小时中性盐雾室试验之前，在环境条件下空气干燥面板。为了耐久试验，将该试样保持于15度的架子中。这些面板与“对比样”并排地试验，所述的对比样是由通过浸渍于200°F的重铬酸钾溶液20分钟或浸渍于200°F的沸水溶液中20分钟来进行后处理的类似阳极化铝组成。
表I，II，III和IV及照片(附图1-6)中的数据表明：下面四种后处理的性能：(1)本发明的(TCP)三价铬后处理，(2)稀铬酸盐，(3)热水后处理和(4)在ASTM-B 117中性盐雾试验曝光而板1000小时之后用热水进行TCP。如表和照片中所示，本发明的TCP后处理提供优异的耐腐蚀性能，并且保留涂层在盐雾室测试之前具有的原始彩虹色。使用2024-T3和7076-T6铝，根据实施例4制备这些测试样。此外，第四种后处理准备如下：通过将阳极化铝浸渍于根据实施例4制备的TCP溶液中来进行后处理。在TCP浸渍之后，将面板浸渍于200°F的去离子水中20分钟。代替检测这些涂层的腐蚀性能，确定涂层的耐酸性能。通过称重每块面板，根据MIL-A-8625F浸渍于铬酸和磷酸的热反提剂中，在去离子水中完全漂洗，并且在环境条件下空气干燥，进行酸溶解试验。干燥之后，再对面板进行称重。所记载的重量损失表明各种后处理耐反提剂的腐蚀性酸环境的能力。
表1所示为对于每一种后处理和阳极化涂层组合，三种不同的面板的平均重量损失。TCP后处理过的和TCP热水后处理过的体系比稀铬酸盐和热水后处理对比样显示更好的性能(更少的涂层重量损失)。对于2024-T3和7075-T6铝上的涂层体系，观察到类似的结果。

虽然本发明已经由许多具体的实施例进行了描述，但显然的是，有其他各种没有离开如后附权利要求具体阐明的本发明的精神和范围内所做出的变化和修改。
