Description
本发明涉及具有低粘度的烷氧基硅烷官能化的异氰酸酯基材料,其制备方法及其用途。
通过水分(通过硅烷缩聚)交联的烷氧基硅烷封端的聚氨酯越来越多地用作建筑和汽车工业中的弹性体涂料,密封和粘合剂组合物。
烷氧基硅烷封端的聚氨酯通常通过使含有聚氨酯预聚物的异氰酸酯与氨基官能性的烷氧基硅烷反应来制备(参见例如DE 102008038399;US 2003/232942;US 6492482)。
这些产品通常具有高粘度,并且因此难以处理。所述高粘度与氢键键合直接相关(由于脲基和氨基甲酸酯基的存在)。因此降低粘度的解决方案已经集中于降低/消除氨基甲酸酯/脲在这些硅烷封端的聚氨酯结构中的含量。
一种降低氢键密度,并且因此降低粘度的这样的方法公开于EP 0372561,其中使用超长链的聚醚多元醇。该方法要求聚醚多元醇具有高官能度和低水平的不饱和性及多分散性。该方法只在为低模数粘合剂而设计的超长链的预聚物的例子中具有显著的效果,并且尽管那样也只可能降低而非消除氢键密度。
降低氢键密度的另外的方法是如US 4345053所公开的,通过使OH-官能性的预聚物与异氰酸酯官能性的烷氧基硅烷反应,得到无脲结构。使用异氰酸酯官能性的烷氧基硅烷的缺点是异氰酸根合硅烷(isocyanatosilanes)数量有限,昂贵并且此外,从毒理学的观点来看,这些硅烷是不能采用的。
US 2007/0055010教导了用于降低脲/氨基甲酸酯密度的另一种可能性,即通过氨基甲酸酯/脲基团与单异氰酸酯的部分或完全的脲基甲酸酯化(allophanatization)和/或缩二脲(biuretization)作用,其空间上阻碍氢键形成。这种末端缩二脲应该与分枝的和链伸长的缩二脲不同。然而该方法需要在制备硅烷封端的聚氨酯之后的另外的合成步骤。此外,单异氰酸酯还具有环境、健康和安全问题。
如US 5539045中所公开的,其它降低粘度的解决方案是使用硅烷封端的聚氨酯结构的混合物,该混合物具有小于组分硅烷化聚氨酯的平均粘度的粘度。
现在已经发现了降低粘度的备选方法。
现在已经发现,在氨基官能性的烷氧基硅烷的N-取代基上利用吸电子基团使不希望的链伸长缩二脲形成(不希望是因为其增加粘度)最小化,得到低粘度的硅烷封端的材料。本发明能够制备无缩二脲的烷氧基硅烷官能化的异氰酸酯基材料。
根据本发明,烷氧基硅烷官能化的异氰酸酯基材料通过多异氰酸酯与异氰酸酯反应性化合物及式I的氨基官能性的烷氧基硅烷以任何可能的添加顺序反应而制备
R-HN-R1-Si-(OR2)3-x(R3)x (I)
其中R代表具有吸电子性能的基团,R1是直链或支链亚烷基或亚芳基,R2和R3相同或不同并且各自代表亚烷基或亚芳基,且x是0、1或2。
多异氰酸酯可以与异氰酸酯反应性化合物预反应以形成所谓的异氰酸酯官能性的预聚物。
根据反应式II,所述多异氰酸酯和/或所述异氰酸酯官能化的预聚物与式I的氨基官能性的烷氧基硅烷的反应得到取代的脲基。
[预聚物]-NCO + R-HN-R1-Si-(OR2)3-x(R3)x →
[预聚物]-NH-CO-N(R)-R1-Si-(OR2)3-x(R3)x (II)。 。
在根据本发明的方法中,在脲键上的不希望的副反应(其通过缩二脲形成产生额外的链伸长)被有效地抑制。根据反应式III,可以通过烷氧基硅烷官能化的异氰酸酯和/或其预聚物与多异氰酸酯和/或异氰酸酯官能化的预聚物反应来形成缩二脲基。
[预聚物]-NH-CO-N(R)-R1-Si-(OR2)3-x(R3)x + [预聚物]-NCO →
[预聚物]-N(CO-NH-[预聚物])-CO-N(R)-R1-Si-(OR2)3-x(R3)x (III)。
令人惊讶地,已经发现选择适当的R基团使其吸电子可以抑制反应III。
优选地,γ-苯基氨基丙基三甲氧基硅烷用作氨基官能性的烷氧基硅烷,其充分抑制缩二脲形成,得到具有较低粘度的材料,该粘度显著低于基于不含有吸电子基团的R基团的类似材料的粘度。

制备本发明的硅烷封端的聚氨酯的一种可能的方法是通过用氨基官能性的烷氧基硅烷完全封端预聚多异氰酸酯。
有机预聚多异氰酸酯和氨基官能性的烷氧基硅烷根据本领域技术人员熟知的方法反应,通常不经稀释(neat)或在溶液中。反应温度通常为-50℃至200℃,优选0℃至125℃,更优选25℃至100℃和最优选25℃至85℃。
可以向反应混合物中添加催化剂。而且,可以向反应混合物中添加水清除剂,例如有机官能性的烷氧基硅烷,优选乙烯基三甲氧基硅烷或乙烯基三乙氧基硅烷。

在本发明硅烷封端的聚氨酯反应产物中的缩二脲含量可以通过13C-NMR分析测定并且可以表示为缩二脲羰基强度对脲羰基强度(来自多异氰酸酯和氨基硅烷的反应)的比例。根据本发明,缩二脲-脲比例通常小于0.5,优选小于0.3和更优选小于0.2。在最优选的实施方案中,缩二脲-脲比例为零(在缩二脲不能被检测的情况下),表明是无缩二脲材料。
相比于在完全相同的条件下合成但用具有非吸电子取代基的氨基硅烷制备的材料,使用本发明中所述的方法可以实现反应产物的显著的粘度降低;获得的粘度降低通常为至少5 %,优选至少10 %,更优选至少20 %和最优选至少50 %。
根据本发明的烷氧基硅烷封端的聚氨酯通常在室温下具有1至500 Pa.s,优选5至200 Pa.s和更优选10至150 Pa.s的粘度。
使用苯基型取代的二级氨基硅烷,缩二脲副反应几乎可以被完全地阻止,由此提供具有最低可能粘度的烷氧基硅烷封端的聚氨酯。此外这些反应产物对由于水分污染而引起的外源性固化较不敏感,因此具有较高的贮存期限。
不与其它组分例如任何分子量的其它异氰酸酯官能化的预聚物/低聚物(无论是否通过预混多元醇或通过分别预聚然后混合而原位产生)、其它硅烷化聚合物或硅酮混合,也可获得低的粘度。
反应产物不是泡沫材料(不添加发泡剂)并且也不是水性乳剂。
本发明的材料非常适用于生产,例如但不限于,应用于建筑部门的聚氨酯密封剂。另外,其适于生产粘合剂,底漆和涂料。
为了制备这种密封剂或粘合剂,这些低缩二脲烷氧基封端的聚氨酯可以与已知添加剂例如增塑剂、填料、颜料、干燥剂、光稳定剂、抗氧化剂、触变剂、催化剂和粘合增进剂通过已知的生产方法配制。
