Description
背景技术
用于容纳食品和饮料的金属容器通常具有一层或多层涂层以防止所填充的产品与金属之间的接触。这是为了防止或尽量减少由产品对金属的腐蚀和对产品质量的任何不利影响。为了制造这种类型的容器，例如镀锡或镀铬钢或铝罐，所用的金属片材在它们成型(例如用于三件套罐产品)或变形(例如深拉处理)之前，已涂覆适当的涂料组合物。在制造食品和饮料用罐时，要求所用涂料需具有非常好的柔韧性和低毒性。此外，装满食品的罐通常采用高至135℃来消毒。因此，涂层在那些温度下必须足够稳定并必须能够附着于金属的表面。
环氧酚醛型涂料已经被用作涂覆于金属罐原料(例如，用于三件套罐)上的漆，经烘干以赋予涂料对侵蚀性的填充产品的良好抵抗性、机械性能和金属粘合性(metal adhesion)。但是，许多这类涂料含有2，2’-双(4-羟基苯基)丙烷-双(2，3-环氧丙基)-醚(或其同系物)，或者称为双酚A-二缩水甘油基醚或“BADGE”(双酚A-二缩水甘油基醚(Bisphenol-A-Di-Glycidyl-Ether))。
使用含有BADGE的配方是食品法方面所禁止的。
目前可得到的聚酯型涂料，例如那些由氨基型或异氰酸酯型树脂所交联的，被用作三件套罐的外涂料，但当与食品接触时其不耐加工，或不符合食品法，因而也还不能提供一种可供选择的涂料配方。
WO 00/55265描述了不含BADGE的组合物，然而，其是在聚酯树脂结合双酚A(BPA)的基础上生产的。以PVC与双酚A交联为基础的有机溶胶作为可选择的聚酯树脂。因此双酚A被优选用于具有消毒耐受性、不含环氧的罐用涂料。但是，已被发现的是双酚A以雌激素类似的方式作用于人体，这可能导致生殖障碍。
聚氯乙烯型的交联的涂料组合物在商业上是可买到的。但是，所有已知的抗病毒的涂料组合物含有BADGE和/或BPA。在本发明的上下文中使用的术语“交联”，是指以共价键连接一聚合物链至另一聚合物链，而术语“交联剂”是指单体或聚合物能够与将其连在一起的聚合物链反应或共反应以形成硬质塑性(duroplastic)网络。
许多已知的用于金属罐的涂料组合物还含有金属稳定剂，如铅基或锡基稳定剂。这些金属稳定剂用于食品和饮料的罐中是不合乎要求的且不符合食品法。
此外，在许多已知的涂料组合物中，在涂覆涂料组合物之前，需要首先在金属表面上涂覆底漆组合物。因为需要更多的、高费用的处理步骤，以及因为许多底漆组合物不符合食品法，这是不利的。
考虑到克服现有技术的不足，需要一种基本不含BADGE和BPA的新的罐用涂料。
发明内容
为克服现有技术的缺点，本发明提供一种用于生产用于金属片材基材例如金属罐或金属罐原料的涂料的组合物，该组合物基本上不含BADGE和BPA。
本发明更进一步地提供可用于生产用于金属片材基材，例如金属罐或金属罐原料的涂料的组合物，且该组合物用于直接在金属表面上应用。
根据更进一步地方面，本发明提供用于生产用于金属片材基材，例如金属罐或金属罐原料的涂料的组合物，该组合物基本上不含金属稳定剂，如铅基或锡基稳定剂。
当将其与食品相接触处理时，依照本发明的组合物提供的金属罐涂料具有适合的柔韧性、抗擦伤性(scratch resistance)、耐用性和抗病菌性。该涂料适合用于三件套罐以及深拉金属罐。比较而言，由于其非凡的柔韧性和抗病菌性，他们尤其适合用于将被拉开的盖子。依照本发明的组合物在高至135℃的高温下是足够稳定的，且当在该温度下处理的时间持续达60分钟时同样是足够稳定的。令人惊讶地是，为达到这种抗处理性不需颜料。
依照本发明的组合物更进一步地用于直接应用于金属表面上而无需涂覆底漆组合物。
该目的通过一组合物来完成，其可用于生产用于储存和/或运输食品或饮料的金属罐或它们的盖子的金属片材基材的涂料，该组合物包括如下组分：
(a)30-90重量％的聚氯乙烯-(PVC)-聚合物，
(b)7-25重量％的丙烯酸树脂，
(c)3-40重量％的交联剂，其由苯酚、对-叔丁基苯酚、二甲苯酚或它们的混合物，以及甲醛生产，
(d)0-8重量％的添加剂，
(e)0-50重量％的颜料，和
(f)溶剂组分，
其中所有重量百分比基于涂料组合物(不含溶剂)的总的干重，该组合物基本不含双酚A-二缩水甘油基醚(“BADGE”)且同样基本不含双酚A树脂。
在本申请上下文中所用的术语“基本上不含”，是指本发明的涂料组合物不含BADGE组分，或BPA，或至少不超过这些组分的最低含量，例如，低于总重的0.01重量％，优选低于总重的0.001％。更进一步地，依照本发明的涂料组合物优选基本不含“BADGE型”组分，例如双酚F-二缩水甘油基醚和酚醛清漆-二缩水甘油基醚。最后，依照本发明的涂料组合物优选同样基本不含其它的环氧基团。
本发明的更进一步地优点和特性在下文中进行讨论。
具体实施方式
此处所提供的所有重量百分比基于涂料组合物的不包括溶剂在内的总的干重。
PVC聚合物(polyer)(a)优选PVC均聚物。优选的PVC聚合物为，例如可从PolyOne购得的商品名为
的170和190系列或购自Vinnolit Kunststoff GmbH的商品名为
P70。PVC聚合物的用量为30-90重量％，优选55-80重量％。
丙烯酸树脂组分(b)优选衍生自丙烯酸或甲基丙烯酸型单体的聚合物。此外，可以使用衍生自丙烯酸或甲基丙烯酸型单体的共聚物或聚合物的混合物。优选的是丙烯酸、甲基丙烯酸酯、乙基丙烯酸酯、丙基丙烯酸酯、丁基丙烯酸酯、戊基丙烯酸酯、己基丙烯酸酯、甲基丙烯酸、甲基丙烯酸甲酯、甲基丙烯酸乙酯、甲基丙烯酸丙酯、甲基丙烯酸丁酯、甲基丙烯酸戊酯、甲基丙烯酸己酯树脂，这些组分的共聚物树脂或它们的混合物。丙烯酸树脂组分的平均分子量优选大于25000g/mol，更优选从35000至100000g/mol，特别优选40000至70000g/mol。丙烯酸树脂组分的玻璃态转变温度优选高于50℃，更优选在55和75℃之间。酸值应优选低于20，更优选低于15。丙烯酸树脂组分的用量为7-25重量％，优选7-18重量％。
交联组分(c)可被表征为缩合产物，其由苯酚或苯酚的同系物(苯酚、丁基苯酚、甲酚、二甲苯酚)和甲醛制得。优选地，交联组分包括苯酚、对-叔丁基苯酚，二甲苯酚或它们的混合物以及甲醛。可商购的且适用于依照本发明的交联剂，是可从Vianova Resins(德国)购得的商品名为
作为选择，可以使用基于尿素、三聚氰胺、六甲氧基三聚氰胺或苯并三聚氰二胺(benzguanamine)和甲醛的氨基树脂。交联组分可以被完全烷基化、部分烷基化或不被烷基化。
交联组分的用量为3-40重量％，优选8-25重量％。
此外，添加剂如控制交联反应速度的促进剂、润滑剂、表面活性剂、粘合助剂(adhesion promoters)、稳定剂、消泡剂、软化剂及类似物可以被加至涂料组合物。
典型的可使用的促进剂为磷酸及其酯和烷基苯磺酸，例如十二烷基苯磺酸，及其酯。它们的用量，例如为0-3重量％，优选0.05-1.0重量％(基于活性物质)。
优选地，涂料组合物进一步地包含润滑剂，其以固态存在并分散在溶剂中或被溶剂化。润滑剂可存在的量为0.1-3重量％，更优选0.1-2重量％。示例的润滑剂可包括聚乙烯(PE)、聚丙烯(PP)、PTFE、羊毛脂、棕榈蜡和矿脂并优选具有小于25μm的粒径。
树脂可以在溶剂或溶剂混合物中被溶剂化。例如，芳香烃如二甲苯，乙二醇或丙二醇醚，醋酸酯，醇如正丁醇，酮或其它可用于罐用涂料的常规溶剂。优选地可用于溶剂化丙烯酸树脂和交联组分的溶剂包括芳香烃(例如，芳香(aromatic)100或芳香150)，乙二醇醚/乙二醇醚乙酸酯(例如，甲氧基丙醇，
