Description
技术领域
本发明涉及烷氧基硅烷官能化的、含有脲基甲酸酯的涂覆剂、其制备方法及其用途。
现有技术
数十年来,聚氨酯被证明是漆料、胶粘剂、密封剂和塑料体系的高品质组分。在此,额外的烷氧基硅烷基团可以起到重要作用,例如在网络密度、耐化学品性和耐刮擦性方面,这里主要是通过形成硅氧烷和聚硅氧烷的结构。
既具有烷氧基硅烷基团又具有异氰酸酯基团的分子实现了通过一种组分引入作为反应产物得到的官能度、硅氧烷和聚氨酯基团。长期以来一直使用这样的物质,例如以异氰酸根合烷基三烷氧基硅烷的形式。
由异氰酸根合烷基三烷氧基硅烷和醇制得的烷氧基硅烷封端的聚氨酯同样是已知的并且例如用于制备高度交联的、硬质涂覆剂 (例如EP 2676982 A1)。然而,在EP2676982 A1中描述的含有烷氧基硅烷的涂覆剂是不利的,因为它们仅具有短的可使用时间(Topfzeiten)。
含有脲基甲酸酯的粘合剂是长久已知的。烷氧基硅烷官能化的脲基甲酸酯也是已知的。这里区分为下面描述的不同类型,但是它们在结构和应用方面都不对应于在本发明的烷氧基硅烷官能化的、含有脲基甲酸酯的涂覆剂中包含的烷氧基硅烷官能化的脲基甲酸酯。
例如,在WO 2008/043722 A1中描述的脲基甲酸酯 III (1) 通过NCO封端的含有脲基甲酸酯的聚氨酯 I (1) 与对异氰酸酯呈反应性的烷氧基硅烷 II (1) (例如氨基烷基三烷氧基硅烷) 的反应而获得。由此,脲基甲酸酯基团位于聚氨酯链的中心和烷氧基硅烷官能团通过末端的异氰酸酯基团连接到脲官能团的结构中 (结构 III (1),反应式1)。
DE102005041953 A1 描述了平均分子量为3000-20000 g/mol 的多元醇 I (2)与过量的异氰酸根合丙基三甲氧基硅烷II (2) 的反应,从而在形成聚氨酯 III (2) 之后形成每个脲基甲酸酯单元具有两个烷氧基硅烷官能团的脲基甲酸酯 IV (2)。
在DE102005041954 A1中,将聚氨酯 I (3) 与异氰酸根合丙基三甲氧基硅烷II(3) 混合并且加热直至形成脲基甲酸酯结构。在这种情况下,将烷氧基硅烷基团结合到脲基甲酸酯基团 III (3) 的末端氮上 (反应式3)。
J. Kozakiewicz等人在Progress in Organic Coatings 72 (2011) 120–130中公开了异氰酸根合丙基三甲氧基硅烷I (4) 与甲醇反应得到相应的氨基甲酸酯 II (4)和随后与六亚甲基二异氰酸酯三聚体 III (4)反应。在由此获得的高粘度脲基甲酸酯 IV(4) 中,烷氧基硅烷官能团挂接到脲基甲酸酯基团的中心叔胺上 (反应式4)。
在所述的应用中,脲基甲酸酯官能团用作六亚甲基二异氰酸酯三聚体的阻隔剂,而六亚甲基二异氰酸酯三聚体用作羟基官能化的聚酯多元醇的交联剂。
即使如今仍然需要新型的、具有特定性质的、含硅烷的涂覆剂。
在EP 2676982 A1中描述的含有烷氧基硅烷的粘合剂是不利的,因为它们仅具有短的可使用时间。
发明内容

VI (对比例) | 2.0 |
从表2给出的可使用时间可以看出,本发明的烷氧基硅烷官能化的、含有脲基甲酸酯的粘合剂 I-II 相比于对比例 III – VI 具有明显更长的可使用时间。从现有技术 (对比例 IV – VI) 不会期望,在使用本发明的烷氧基硅烷官能化的、含有脲基甲酸酯的粘合剂 I-II的情况下,可使用时间延长四倍。
为了测定机械表征数据,将所有漆料以120 µm刮涂到磷化钢板 (ChemetallGardobond 26S/60/OC) 上,并且在160℃下固化22分钟。
表3:在160℃ (22 min)下固化之后的组合物I-III的漆料性能
包含本发明的烷氧基硅烷官能化的、含有脲基甲酸酯的粘合剂组分 1和2 的涂层I和II的漆料性能显现出大约相同的摆锤硬度和MEK耐受性,但比对比例III改进的粘合性(交叉线)。特别是在包含三倍官能化的对比例3的配方III的情况下,由于更高的交联度而会期望相比于包含本发明的烷氧基硅烷官能化的、含有脲基甲酸酯的粘合剂组分 1和2 的涂料I和II的更高的硬度。
