Abstract

本发明涉及聚氨酯涂料,它按照浇铸或分布涂覆工艺,用反应组分施加到诸如纤维或皮革的弹性基材上。

Description

聚氨酯涂料
本发明涉及聚氨酯涂料,可通过将基于含异氰酸酯化合物和多元醇的反应性组合物(反应性粘合剂)用浇铸或刮涂方法加到诸如纺织品或皮革的弹性基材上进行制备。
用于制备弹性基材上的聚氨酯涂料的基于NCO预聚物的无溶剂和低溶剂的反应性组合物是已知的。例如,EP-A 0 490 158揭示了制备聚氨酯涂料的方法,其特征是高反应性。就其高反应性而言,这类方法由于其贮存期极短,故仅适合喷洒施加,而不可使用浇铸或刮涂工艺。另一方面,基于封端的多异氰酸酯(blocked polyisocyanates)的系统,如封端的NCO预聚物和脂环族二胺的组合,则适合这类涂覆工艺。此时,基于芳族多异氰酸酯的酮肟封端的NCO预聚物与作为链增量剂的二胺混合,然后通过热处理使酮肟裂解而固化,并任选地蒸发溶剂。在DE-A 2 902 090中揭示了这类用于涂覆弹性基材的反应性组合物。当所述的系统固化时,酮肟发生裂解,即使系统不含溶剂时,也需要处理废气。
另一方面,EP-A 0 825 209揭示了没有裂解产物的反应性粘合剂,这些产品就其有利的反应动力学和极佳的机械膜性质来说很适合用于涂覆纺织品和其它平坦的基材。不利之处在于,单体含量低的反应性粘合剂的制备在技术上更为复杂(由薄膜蒸馏分离单体)。
因此,本发明的目的是提供可从单体含量低、且无需单体分离即可制备的反应性粘合剂得到的聚氨酯涂料。
令人惊奇的是,通过使含有脲基二酮(uretidione)或噁二嗪三酮的特定多异氰酸酯预聚物和特定的二醇链增量剂的组合,可以得到具有良好机械性能的涂料,它能满足弹性基材,例如纺织品的涂覆,因此达到了该目的。
因此,本发明提供了聚氨酯涂料,其特征在于,它们可通过使脂族的含异氰酸酯的预聚物A)与多元醇组分B)反应得到,其中
预聚物A)中:
以固体为基,含有1-8重量%NCO,其游离单体二异氰酸酯含量低于2%,每1000克预聚物含有0.1-1.5摩尔脂族连接的脲基二酮(I)和/或噁二嗪三酮基团(II):

和其中A的游离NCO基团与B的NCO-反应性基团的当量比为0.90到1.50,任选地使用常规的辅剂和添加剂,本发明还提供其用来涂覆诸如纺织品或皮革的弹性基材的用途,和用于例如通过浇铸或刮涂来涂覆所述基材,然后热处理的方法,并提供涂覆的基材本身。

含有脲基二酮基团的工业上可得的脂族多异氰酸酯a)通常是含有异氰脲酸酯、亚氨基噁二嗪二酮、脲基甲酸酯或缩二脲结构的混合物。这类产品的一个例子是DesmodurN 3400(Bayer AG.德国),一种基于六亚甲基二异氰酸酯的多异氰酸酯,除了脲基二酮基团外,主要含有异氰脲酸酯基团,因此平均NCO官能度为约2.5。宜使用基于六亚甲基二异氰酸酯的含脲基二酮基团的多异氰酸酯。

通过使含有脲基二酮和/或噁二嗪三酮的多异氰酸酯a)与多羟基组分c)在约40℃到100℃下反应来制备组分A),NCO/OH比为1.5∶1到5∶1,优选的是1.7∶1到4∶1。
若使用其它多异氰酸酯b),对于双官能团类型,它们可用于初步延伸多羟基化合物c)。优选地使较高官能度类型与a)混合,或随后加入。为了得到最佳的加工粘度20,000到40,000mPa(20℃),组分A)可与,以NCO预聚物为基,最高达30重量%,优选的是最高达20重量%的有机溶剂,如乙酸甲氧基丙酯或乙酸丁酯,混合。
组分B)优选地由(基于对异氰酸酯为反应性的基团)大于80当量%,优选的是100当量%的式III化合物组成。优选的化合物III是在低于50℃温度下不溶于预聚物A的化合物。特别优选的化合物III包括,例如,1,2-双(2-羟基乙氧基)苯、1,3-双(2-羟基乙氧基)苯、双-1,4-(羟甲基)苯、反-1,4-双(羟甲基)环己烷、1,2-双(4-羟基环己基)乙烷、双(4-羟基环己基)甲烷、丁-2-炔1,4-二醇。特别优选的化合物III是1,4-双(2-羟基乙氧基)苯。
化合物B)可直接与预聚物混合,以制备反应粘合剂。但是,为了改进计量,业已证明使通常为固态的化合物III混合入液体组分中是有利的。这类混合物优选地由20-90重量%,最好是30-70重量%化合物III,10-80重量%,最好是30-70%液体组分和0-10重量%,最好是0.1-5重量%其它添加剂,如分散剂,抗沉积剂,催化剂等等组成。液体组分可为上述高分子量多元醇之一和/或不与异氰酸酯反应的增塑剂,和/或任何溶剂。这类溶剂的例子是常规的油漆溶剂:诸如乙酸丁酯的酯,诸如乙酸甲氧基丙酯的醚酯,诸如丙酮和2-丁酮的酮类,诸如二甲苯、甲苯的芳烃类或工业上的芳族或脂族混合物或诸如N-甲基吡咯烷酮、N,N-二甲基乙酰胺、N,N-二甲基甲酰胺和二甲亚砜的极性溶剂或各种溶剂的混合物。
优选溶剂作为液体组分。毒性低于临界的脂族酯或醚酯,如乙酸甲氧基丙酯或乙酸丁酯是最为适宜的。
为了保证膜的良好的表面结构,若固体化合物III以细分散状态存在证明是有利的。优选的粒径分布为d90=1-80微米,d99=5-120微米,优选的d90=3-40微米,d99=5-60微米。化合物III然后通常用溶解器掺入液体组分,但是,它也可通过重结晶将化合物III的超饱和溶液转化为所需的分散液或从熔体分散化合物III。也可以在涂料工业常用的珍珠磨中进行制备。
通过特殊的添加剂,如氢化蓖麻油、聚脲衍生物或特殊的硅石可有利地影响流变性质和沉积行为(参见J.Beilman,“Lackadditive”,Wiley-VCH-Verlag GmbH,1998)。特别是,聚合物添加剂适合用作分散剂。它们优选地由化学上不同的链段组成,根据结构,可与被分分散的颗粒表面相互作用,或作为溶剂化链对空间稳定化起作用。能与本发明的颜料或填料颗粒或与交联剂组分B中的结晶化合物III相互作用的官能团例子是羰基、氨基、硫酸酯或磷酸酯基团。能稳定化颗粒的聚合物链段的例子是聚醚、聚酯或聚丙烯酸酯。
根据本发明使用的催化剂可用作组分B的成分或作为任何溶剂里的催化剂溶液,其用量占组分A+组分B总重量的0.001-2,优选的是0.005-0.5重量%。本发明中最好的催化剂是二辛基锡-IV-双(2-乙基己基巯基乙酸酯)、二丁基锡-IV-双(2-乙基己基巯基乙酸酯)和二甲基锡-IV-双(2-乙基己基巯基乙酸酯)和如US-A 4 788 083中揭示的锡或铋化合物和巯基化合物的潜在的催化剂。
本发明中,NCO预聚物A通常与链增量剂组分B以大致相当重量的比例混合,但在一些场合下欠固化是有利的,结果NCO和OH的当量比一般是0.90-1.50,优选的是1.0-1.3。
可加入诸如颜料、UV稳定剂、均化剂、抗氧化剂、填料或发泡剂的添加剂来制备备用的反应性组合物。
可使用如J.Beilman,“Lackadditive”,Wiley-VCH-Verlag GmbH,1998中揭示的涂料辅剂种类。更具体的是,均化剂和分散剂和流变添加剂适合用来制备本发明的组合物。例如,基于二硅氧烷的添加剂可用来改进表面性质。特别是,基于聚丙烯酸酯的添加剂适合用来改进流动性。诸如氢化蓖麻油、聚脲衍生物或特殊硅石的特殊添加剂对含有填料和颜料的组合物的流变性质和沉积行为产生有利的影响。
可加入本发明组合物的涂料添加剂的用量为0.01-0.5重量%,优选的是0.05-3重量%。
此外,阻燃添加剂可加入本发明组合物中。该术语表示固体或液体物质,其被加入后会改善固化的聚合物膜的防火性能。这些试剂在Journal ofCoated Fabrics 1996,第25卷,224ff中有所阐述。特别适合用于本发明组合物的是无卤和无锑的阻燃剂,如磷酸或硼酸衍生物、碳酸钙、氢氧化铝、氢氧化镁或蜜胺和蜜胺衍生物。蜜胺和其衍生物,如硼酸蜜胺或蜜胺异氰脲酸酯最为适宜。加入本发明组合物中阻燃剂的用量占组分A+B总量的2-70重量%,优选的是5-35重量%。
本发明的反应性组合物优选地通过直接刮涂(分布涂覆)方法或反转辊涂覆来加工。
本发明组合物的固化时间是2-18分钟,优选的是6-12分钟。固化时间短使高速涂覆成为可能。很自然,可以通过调节每种情况下NCO预聚物的特定化学结构产生具有不同性质的膜,如结合涂层、泡沫涂层、中间涂层或面涂层。
用下列方法可制备,如反转辊涂层:将面涂的反应性组合物以约30-100克/米2的量最初施加在合适的中间载体,如剥离纸上,组合物在烘道中干燥,用于结合涂层的反应性组合物同样以30-100克/米2的量施加于干燥的面涂层上,将基材层压其上,再在约120-190℃(较佳140-170℃)的烘道中固化涂层,将涂覆的基材从剥离载体中移下。当然,也可以用该涂覆方法,并使用其它现有技术中的涂覆系统仅生产面涂层,中间涂层或结合层。
如前所述,该反应性组合物也可通过直接分散涂覆方法立即施加在纺织品基材上。在该情况下,本发明反应性组合物的无裂解产物和低溶剂的特性在制备厚的平涂层中是很有利的。用该方法,仅仅施加一次100-200克/米2即可得到约0.4毫米厚度的工业涂层。
若用本发明的反应性组合物制备泡沫层,可向其加入鼓泡剂和泡沫稳定剂。DE-A 1 794 006和US-A 3 262 805中揭示了合适的添加剂。
