Abstract
本发明涉及一种裸露板材或镀锌钢板，在其至少一面上还用含有0.15－1重量％的聚合物的单层锌或锌合金对其进行涂层，所述聚合物由6－150个相同或不同的以下通式的单元组成：－(CH2－C(R)(CONH2))－，其中R＝H或CH3，且所述聚合物任选包含聚烯丙基单元，以及通过在硫酸盐浴中的电镀制备所述板材的方法。
Description
本发明涉及一种涂覆有包含聚合物的锌或锌合金的涂层的裸露钢板或镀锌钢，并涉及一种通过电镀制造所述板材的方法。所述板材更特别用于制造汽车。
在汽车车身的封闭区域或弯曲区域中，可能发生加速腐蚀现象。汽车制造商可单独或结合采用多种方案避免这种现象。一种方案是使用覆盖有通过电镀或通过镀锌沉积的锌层的钢板，所述锌层本身覆盖有通过涂覆工艺沉积的薄有机涂层。
按照惯例，当需要采用有机涂层(不论是薄有机涂层或涂料层)涂覆金属表面时，进行预先的表面处理，其主要目的是确保有机涂层粘着到金属表面上。在最通用的表面处理中，可提及的是铬酸盐处理、磷酸盐处理、基于硅烷的处理或基于钛的处理。表面处理的选择取决于随后的有机涂层的化学性质。
如果要求随后的涂层适当粘着，这些处理是必要的，但它们的使用也引起许多问题。因此，它们的沉积作用要求存在用于实施处理的专用设备，如在磷酸盐处理的情况下，产生的废水的处理可能是昂贵的；并且特别是在铬酸盐处理的情况下，所使用的一些产品在环境上是有毒的。
在基于钛的处理的具体情况下，由于产生令人满意的性能的涂层用量范围窄，因而还必须确保精确控制涂层用量。
关于基于硅烷的处理，这相对较难以处理，并且特别是在主要涂料层的阳离子电泳沉积之前有被汽车制造商所使用的除油和磷化溶液降解的危险。
因此，本发明的目的是通过提供一种使得薄膜有机涂层直接随后粘着的涂覆板材克服现有技术的缺点，而对环境没有损害并提高了生产率。
为此，本发明的第一个主题是一种裸露板材或镀锌钢板，其特征在于所述板材在至少一个面上涂覆有含有0.15-1重量％的聚合物的单层锌或锌合金，所述聚合物包含6-150个具有以下通式的相同或不同的单元，优选至多80个相同或不同的单元，且有利的是20-30个相同或不同的单元：
-(CH2-C(R)CONH2))-
其中，R＝H或CH3；并且所述聚合物任选包含聚烯丙基单元。
在第一个优选的实施方案中，根据本发明的板材依次包括：
-钢层；然后
-含有所述聚合物的单层锌或锌合金；并且然后
-基于环氧树脂的涂层，可任选向其中加入聚氨酯树脂，所述基于环氧树脂的涂层任选包含导电颗粒，如锌颗粒和/或磷化铁。
在该实施方案中，板材还可另外包括夹在钢层与含有聚合物的单层锌或锌合金之间的锌层。
在另一个优选的实施方案中，根据本发明的板材依次包括：
-钢层；然后
-含有所述聚合物的单层锌或锌合金；并且然后
-基于聚氨酯的涂层，其任选包含导电颗粒，如锌颗粒和/或磷化铁。
在该实施方案中，板材还可另外包括夹在钢层与含有聚合物的单层锌或锌合金之间的锌层。
如在其各种实施方案中所定义，根据本发明的板材另外可以是含有聚合物的单层锌或锌合金又覆盖有选自聚氨酯、环氧树脂、聚酯及其共混物形成的有机涂层的板材，此外所述有机涂层可以包含导电颗粒。
其涂层的聚合物含量为0.15-1重量％，优选0.15-0.60重量％。
本发明的第二个主题是制造根据本发明的板材的方法，其中使裸露钢板或镀锌钢板穿过电镀浴，并且使近似恒定的平均电流密度为60-160A/dm2的电镀电流在所述板材和置于所述电镀浴中的至少一个阳极之间通过。所述电镀浴包含硫酸锌、至少一种载体盐、0.8-1.2克/升的聚合物，所述聚合物含有6-150个R＝H或CH3的通式-(CH2-C(R)CONH2))-的相同或不同的单元，且优选至多80个相同或不同的单元；并且所述聚合物任选包含聚烯丙基单元。所述电镀浴具有的pH为0-3。
此外，根据本发明的方法可单独或组合具有以下特征：
-电镀浴中的聚合物浓度为0.9-1.1克/升；
-使裸露钢板或镀锌钢板以速度为50-150m/min穿过电镀浴；
-电镀浴中的Zn2+离子浓度为40-100克/升；
-电镀浴的温度为30-70℃；和
-平均电流密度少于120A/dm2。
本发明在于将锌涂层沉积到裸露钢板或镀锌钢板上，所述锌涂层在锌涂层的表面上和/或厚度中结合有特定的有机分子。
关于随后的有机涂层，如此涂覆的板材显示出优异的粘着性，而不需要进行在环境上有毒的预处理。
从实用的立场考虑，可通过任一种适合的方法沉积复合(锌/有机聚合物)涂层。具体地说，可在真正的电镀操作之前将有机分子加入到电镀浴中。然后用于电镀金属涂层的常规条件下使涂层沉积。将存在于电镀浴中的有机分子结合到金属涂层的厚度中和/或表面上，从而引起复合(锌+有机分子)涂层的形成。但是，发明人已证明，当电镀浴中的聚合物浓度不足，即少于0.8克/升时，聚合物结合到复合涂层中不足。在高于1.2克/升的聚合物的情况下，复合(锌/聚合物)涂层的外观劣化。电镀浴中的聚合物浓度优选为0.9-1.1克/升。可将涂层仅沉积到钢板的一面或沉积到两面。
可用于实施根据本发明的方法的电镀浴基于硫酸盐并包括，具体地说，硫酸锌、和至少一种载体盐以及根据本发明的有机分子。
如果必要，其pH可通过加入适当的酸进行调节。如上所述，pH必须为0-3。这是因为在pH高于3的情况下，由于电镀浴具有不足的导电性，因而不能使复合(锌/聚合物)涂层沉积。发明人已证明，复合(锌/聚合物)涂层在基材上的沉积仅在平均电流密度高于60A/dm2时开始。但是，为了抑制复合涂层与随后的有机涂层的粘着性降低，电流密度必须保持在160A/dm2以下。由于在160A/dm2以上到达复合(锌/聚合物)涂层的烧伤极限，产生暗淡和树枝状外观的涂层。电流密度优选少于120A/dm2，因为发明人已证明，高于该值有机涂层的粘着性开始降低并且，为了避免这种降低，还必须同时提高钢板穿过电镀浴的速度。
当钢板的运动速度高于150m/min时，复合(锌/聚合物)涂层的沉积不足以使随后的有机涂层的粘着性充足。如果运动速度少于50m/min，由于降低了在其以上开始发生复合涂层的烧伤的临界电流密度，有机涂层的粘着性不足。
电镀浴的Zn2+离子浓度必须少于100克/升，因为发明人已证明，在高于100克/升的情况下有机涂层的粘着性不足。为了避免复合涂层的烧伤问题，该浓度必须高于40克/升。
除非必须，由于工业上在温度高于70℃下操作是不可想象的，电镀浴的温度为30-70℃。此外，在低于30℃下，电镀浴的导电性不足以将复合涂层适当沉积到板材上。
在另一个实施方法中，还可以再次通过电镀沉积双层(锌/(锌+有机分子))涂层。在这种情况下，必须具有两种不同的电镀浴，即标准电镀锌浴和已向其中加入有机分子的电镀锌浴。然后在生产线的第一电解槽上使用纯锌浴以便沉积第一层锌层，而在生产线末端的电解槽上使用富含有有机分子的电镀锌浴以便沉积第二层锌/有机分子层。
在不希望受一种理论束缚的前提下，本发明人相信，存在于锌涂层表面上的有机官能团可用作调节有机涂层的基底，从而确保在无任一种事先表面处理的情况下将其粘着到金属涂层上。
在本发明的范围内所使用的分子为含有6-150个以下通式的相同或不同的单元，优选最多80个相同或不同的单元，且有利的是20-30个相同或不同的单元的聚合物：
-(CH2-C(R)(CONH2))-
其中R＝H或CH3，
且所述聚合物任选包含聚烯丙基单元。
更特别优选诸如聚丙烯酰胺或聚甲基丙烯酰胺以及聚丙烯酰胺/聚烯丙基共聚物的聚合物。
下述实施例解释说明本发明，但不对其进行限定。
实施例1
制备具有如下组成的电镀浴：
-ZnSO4·7H2O： 287.5克/升，
即，65克/升的Zn2+
-H2SO4： 85克/升；
-聚丙烯酰胺，由M4表示，
作为50wt％的水溶液 1克/升
水溶液(M4：其中R基团为H、1500g分子量、含有约25个单元的聚丙烯酰胺)。
电镀浴的pH为约0，且电镀浴的温度维持在40-60℃。
将钢板沉积在阴极上。将阴极面对不溶性阳极放置。使预先制备的载体盐以接近100m/min的速度流入阴极与阳极之间的间隙(阴极与阳极之间的间隙的宽度为10mm)。然后使约100A/dm2的电流流过直至获得涂层厚度为7.5μm。如此沉积的Zn/M4复合涂层具有极均匀的外观。
使用辊式涂覆机，将购自Henkel的Granocoat LC型的含有磷化铁的基于聚氨酯树脂的有机层施涂到涂有Zn/M4的面上。涂层具有的厚度为6-8μm。如此涂覆的板材A符合本发明。
为了比较，还制备了根据现有技术涂覆的两种钢板：
-覆盖有7.5μm的纯锌层，然后直接覆盖有Granocoat LC层的钢板B；
和
-覆盖有7.5μm的纯锌层，然后使用由Henkel所售的Granodine 1456溶液(基于钛)获得转换表面处理，然后覆盖有Granocoat LC层的钢板C。
纯锌涂层在现有技术(电镀浴中无M4)的条件下生产。使用辊式涂布机施涂Granodine 1456并且沉积的涂层重量在供应商所推荐的范围内(即，8-12mg/m2沉积的钛)。
接着，使用以下操作方法进行Granocoat LC有机涂层粘合到三种金属基材上的试验：
·通过变形从未涂覆的一面生产两个深度为8mm的Erichsen杯；
·将标准化的3M胶带施于两个杯子之一的涂覆的表面上；和
·将胶带撕下并根据以下参数评价有机涂层的撕裂：
-0：没有撕裂
-5：完全撕裂
·接着，将如此变形的板材浸在汽车制造商使用的常规除油和磷化浴中；
·将标准化3M胶带再次施于第二个杯子的涂覆的表面上；和
·将胶带撕下并根据相同的参数评价有机涂层的撕裂。
因此获得有机涂层粘合的两个参数：一个是在将板材通过除油和磷化浴之前；且另一个是在通过所述浴液之后。
以上试验的结果列于下表中：
| 除油和磷化之前的粘着性 | 除油和磷化之后的粘着性 | |
| 根据本发明的板材A | 0 | 0 |
| 比较板材B | 5 | 5 |
| 比较板材C | 0 | 0 |
所得到的结果表明，直接施涂到Zn/M4涂层的有机涂层的粘着性优异并且与锌+预处理+有机涂层形式的粘着性具有相同的性能水平。
但是，根据现有技术直接将有机涂层粘合到纯锌基材上导致就粘着性而言不能接受的结果。
实施例2
如实施例1中进行的试验中所述，制备在相同条件下获得的涂覆有Zn/M4层的钢板。
使用辊式涂覆机，将Bonazinc 3005型(由PPG所售)的含有锌微球体的基于环氧树脂的涂层施涂到涂有Zn/M4的一面。涂层具有的厚度为5-6μm。如此涂覆的板材D符合本发明。
为了比较，还制备了根据现有技术涂覆的两种钢板：
-覆盖有7.5μm的纯锌层，然后直接覆盖有Bonazinc 3005层的钢板E；
和
-覆盖有7.5μm的纯锌层，然后覆盖有Nupal型(由PPG所售)的基于硅烷的预处理层，然后覆盖有Bonazinc 3005层的钢板F。
纯锌涂层在现有技术(电镀浴中无M4)的条件下生产。使用辊式涂布机施涂Nupal，沉积的涂层重量在供应商所推荐的范围内(即，80-120mg/m2固体)。
试验结果列于下表中：
| 除油和磷化之前的粘着性 | 除油和磷化之后的粘着性 | |
| 根据本发明的板材D | 0 | 0 |
| 比较板材E | 5 | 5 |
| 比较板材F | 0 | 0 |
这些结果表明，直接施涂到Zn/M4涂层的环氧树脂型有机涂层的粘着性优异并且与锌+基于硅烷的预处理+环氧树脂形式的粘着性具有相同的性能水平。
但是，根据现有技术直接将有机涂层粘合到纯锌基材上再次导致就粘着性而言不能接受的结果。
实施例3
制备各种钢板(G-U)，这些钢板涂覆有锌/聚丙烯酰胺层，所述涂层通过在下表中所给出的浓度(克/升)、pH、温度T、载体盐速度V和电流密度CD的条件下，在含有硫酸锌(ZnSO4·7H2O)、硫酸(H2SO4)和其R基团为H、具有可变分子量MW、具有50wt％的水溶液的聚丙烯酰胺(PAC)的电镀浴中电镀获得：

| 板材J | 373.6 | 20 | 1 | 1 | 1500 | 150 | 100 | 30 |
| 板材K | 373.6 | 20 | 1 | 1 | 1500 | 100 | 100 | 60 |
| 板材L | 373.6 | 20 | 1 | 1 | 1500 | 30 | 100 | 60 |
| 板材M | 373.6 | 20 | 1 | 1 | 1500 | 150 | 100 | 60 |
| 板材N | 373.6 | 20 | 1 | 1 | 1500 | 100 | 60 | 60 |
| 板材O | 373.6 | 20 | 1 | 1 | 1500 | 100 | 120 | 60 |
| 板材P | 373.6 | 20 | 1 | 1 | 1500 | 100 | 140 | 60 |
| 板材Q | 527.5 | 20 | 1 | 1 | 1500 | 100 | 100 | 60 |
| 板材R | 373.6 | 0.2 | 3 | 1 | 1500 | 100 | 100 | 60 |
| 板材S | 373.6 | 2.2 | 2 | 1 | 1500 | 100 | 100 | 60 |
| 板材T | 373.6 | 2.2 | 2 | 1 | 1500 | 100 | 60 | 60 |
| 板材U | 373.6 | 20 | 1 | 0.15 | 10000 | 100 | 100 | 60 |
当ZnSO4·7H2O浓度分别为373.6克/升和527.5克/升时，Zn2+的浓度分别为85克/升和119克/升。10000分子量的聚丙烯酰胺含有约166个单元。
为此，将钢板沉积在阴极上。将阴极面对不溶性阳极放置。使预先制备的载体盐以速度V流入阴极与阳极之间的间隙(阴极与阳极之间的间隙的宽度为10mm)。然后以电流密度CD使电流流过直至获得涂层厚度为7.5μm。如此沉积的Zn/聚丙烯酰胺复合涂层具有极均匀的外观。
使用辊式涂覆机，将Granocoat ZE型(由Henkel所售)的含有锌珠的包含基于环氧/聚氨酯的树脂的涂层施涂到涂有Zn/聚丙烯酰胺一面。
为了比较，还制备了根据现有技术涂覆的两种钢板：
-覆盖有7.5μm的纯锌层，然后直接覆盖有Granocoat ZE的钢板V；
-覆盖有7.5μm的纯锌层，然后覆盖有使用由Henkel所售的Granodine1457溶液(基于钛)获得的转换表面处理物，然后覆盖有厚度为4μm的Granocoat ZE层的钢板W。
纯锌涂层在现有技术(电镀浴中无聚丙烯酰胺)的条件下生产。使用辊式涂布机施涂Granodine 1457，沉积的涂层重量在供应商所推荐的范围内(即，8mg/m2钛)。
接着，在实施例1中进行的试验中所述的操作条件下，在十七种钢板上进行Granocoat ZE有机涂层的粘着性试验。
根据以下参数评价有机涂层的撕裂：
0：没有撕裂
1：非常轻微的撕裂
2：轻微撕裂
3：中等撕裂：刚刚可接收的限度
4：大量撕裂
5：完全撕裂
粘着性试验的结果列于下表：
| 除油和磷化之前的粘着性 | 除油和磷化之后的粘着性 | |
| 比较板材G | 0 | 5 |
| 比较板材H | 0 | 5 |
| 根据本发明的板材I | 0 | 1 |

结果显示，直接施涂到复合(锌/聚合物)涂层上的基于环氧/聚氨酯树脂型的有机涂层的粘着性与锌+基于钛的预处理+环氧/基于环氧/聚氨酯树脂形式的粘着性具有相同的性能水平，条件是：
-聚丙烯酰胺的浓度为0.8-1.2克/升，且优选为0.9-1.1克/升。这是因为，
当聚丙烯酰胺的浓度为0.2或0.5克/升(板材G和H)时，不足以获得有机涂层的良好的粘着性。
-根据本发明，聚丙烯酰胺的单元数不超过150个。这是因为，当使用含有约166个单元的根据本发明的通式的聚丙烯酰胺(板材U)时，有机涂层的粘着性不足。如本发明人所发现，10000分子量的PAC的浓度大大降低，当其浓度为1克/升，则复合涂层的外观大大劣化，而这是不可接受的。因此，当聚丙烯酰胺链的长度增加，并且特别是在长度方面高于150个单元时，根据本发明在保持电解浴中聚合物浓度在1克/升使涂层的外观劣化，或在降低电解浴中聚合物的浓度的同时获得有机涂层的不足的粘着性；和
-当电流密度为120-160A/dm2时，通过提高电流密度调节速度以便避免复合(锌+聚合物)涂层烧伤的现象。采用相同的方法，当板材的速度(或在根据本发明的试验中的电解液的速度)降低时，还必须确保使电流密度降低以便避免复合(锌+聚合物)涂层烧伤的现象。
