Abstract
本发明涉及用于制备二异氰酸酯的三聚物和/或低聚物的方法。
Description
技术领域
聚氨酯是涂料-、粘合剂-、密封剂-和塑料工业的有价值的原材料。它们大都由多异氰酸酯和醇组分的反应制得。为了确保足够的稳定性,使用具有≥2的官能度的多异氰酸酯是有利的。为此目的,特别经常使用由二异氰酸酯的三聚化和低聚化产生的异氰脲酸酯。此外,通过这样的反应降低了易挥发并因此有毒理学危险的二异氰酸酯的比例。然而,迄今为止,在这种三聚化步骤之后,需要对过量的单体二异氰酸酯进行昂贵且复杂的蒸馏除去。
背景技术
已经记载有混合的三聚化。例如,在DE 1954093中,使HDI和TDI一起三聚,并且借助于短程或薄层蒸馏除去过量的单体。在EP0696606中,该方法可如下改进,即,即使没有蒸馏,也可以通过高含量的脂族NCO基团将芳族残余单体的比例降低至低于0.5重量%。然而,两者的共同之处在于,一方面使用非UV-稳定的芳族异氰酸酯,而另一方面,高比例的低沸点单体异氰酸酯保留在最终产物中。中国专利CN103450443A(芳族和脂族混合的异氰脲酸酯固化剂的制备方法)中也显得非常类似。
DE19642324中涉及环己基二异氰酸酯和芳族二异氰酸酯的混合三聚化。这里不需要蒸馏除去单体,但是这里非光稳定的芳族组分也保留在最终产物中。
在US258482中,使HDI和H12MDI的混合物在事先加入一元醇后三聚,因为它起到必要的助催化剂的作用。三聚化之后,必须用抑制剂使三聚催化剂失活。蒸馏除去单体二异氰酸酯后,相应的最终产物具有比相应的对比产物更低的粘度。醇的使用(降低官能度和NCO含量)和添加抑制剂的需要都限制了这种教导的工业可用性。
在DE19627825中,将环己基二异氰酸酯与其他二异氰酸酯(例如HDI、IPDI)的混合物混合三聚。随后,蒸馏除去残余单体含量。
在"Synthesis of HDI/IPDI hybrid isocyanurate and its application inpolyurethane coating",Progress in Organic Coatings 78(2015)225-233中,将HDI和IPDI混合三聚,以在应用中获得优点,例如较高的TG 或者更好的DOI。
过去也付出了许多努力去降低原料或配制剂中低沸点单体二异氰酸酯的比例。这通常借助于蒸馏方法来完成,但这意味着额外的设备耗费以及温度负荷,这又会导致产品的改变,例如变色。
在低浓度下,异氰酸酯已经显示出对人的急性和慢性作用。因此,根据TRGS 900,二异氰酸酯的工作场所极限值为0.02至0.05 mg/m3。除了物质特有的毒理作用外,二异氰酸酯的蒸气压和沸点也不同。例如,在相同的起始条件下,取决于蒸气压和沸点,不同大小的二异氰酸酯量会释放到环境空气中,这意味着允许的限值将更早、更晚达到或永远达不到。在这方面,在工作场所卫生的意义上,尽可能避免具有高蒸气压或低沸点的二异氰酸酯显得是有利的。下文中仅指出了沸点,因为它一方面与蒸气压密切相关,而另一方面可以从文献或计算中更可靠得多地获悉。
为了更简单的评估,应将二异氰酸酯根据它们的沸点分成三类,因为随着更高的沸点,挥发性和因此危险性下降。应将具有<250℃沸点的二异氰酸酯称为易挥发的,将具有250-350℃沸点的二异氰酸酯称为中等挥发性的二异氰酸酯,并且将具有高于350℃的沸点的二异氰酸酯称为难挥发的。
如果尝试通过尽可能完全的三聚化/低聚化来制备具有低二异氰酸酯单体含量的异氰脲酸酯,则观察到两种不希望的效果。一方面,随着反应的进程(转化度),粘度急剧增加(低聚度或平均摩尔质量增加)。另一方面,在NCO基团的最小浓度下,该反应越来越强烈下降,因此即使在溶剂中也不能实现进一步转化。因此,在反应后,在最终产物中保留了不希望的单体二异氰酸酯部分。必须通过蒸馏将这些单体从最终产物中除去。
发明内容
因此,本发明的目的是,由易挥发和/或中等挥发性的二异氰酸酯制备异氰脲酸酯,该异氰脲酸酯具有低的易挥发和/或中等挥发性的二异氰酸酯的单体含量,而不必求助于复杂且增加负荷的蒸馏除去步骤。
已经令人惊讶地发现,沸点高于350℃的二异氰酸酯,例如H12MDI,可以用作溶剂,以使其中的易挥发和/或中等挥发性的二异氰酸酯如此三聚,以至于可以省略易挥发和/或中等挥发性的单体二异氰酸酯的蒸馏除去。

原则上,适用于三聚化的二异氰酸酯可以按照不同种类的方法来制备(Annalender Chemie 562(1949),第75页及其以后几页)。技术上特别得到证明的是通过将有机多胺光气化成相应的聚氨基甲酰氯(Polycarbaminsäurechloriden)及其热裂解成有机多异氰酸酯和氯化氢来制备。或者,也可以不使用光气,即按照无光气的方法来制备有机多异氰酸酯。根据EP-A-126 299(USP4,596,678),EP-A-126300(USP4,596,679)和EP-A-355,443(USP5,087,739)的说明,例如可以通过作为基础的(环)脂族二胺与脲和醇的反应得到(环)脂族二氨基甲酰酯(Biscarbaminsäureestern)并将其热裂解成相应的二异氰酸酯和醇来得到(环)脂族二异氰酸酯如1-异氰酸根合-3-异氰酸根合甲基-3,5,5-三甲基环己烷(异佛尔酮二异氰酸酯或IPDI)。

本发明非常特别优选的主题是由二异氰酸酯构成的三聚物和/或低聚物和单体二异氰酸酯的组合物,
其可通过
I.5-94.999重量%的
B)异佛尔酮二异氰酸酯 (IPDI)

合适的三聚催化剂例如是叔胺(US 3,996,223),羧酸的碱金属盐(CA 2113890;EP 56159),季铵盐(EP 798299; EP 524501; US 4,186,255; US 5,258,482; US 4,503,226; US 5,221,743),氨基硅烷(EP 197864; US 4,697,014)和季羟烷基铵盐(EP 17998;US 4,324,879)和/或季鏻盐。取决于催化剂,也可以使用各种助催化剂,例如OH官能化的化合物或由仲胺和醛或酮形成的曼尼希碱。
为了进行该反应,在催化剂存在下,任选地使用溶剂和/或助剂,使二异氰酸酯反应,直到达到所希望的转化率。此后,可以通过使催化剂失活来中止反应。这通过添加催化剂抑制剂来进行。在以工业规模三聚化二异氰酸酯方面,特别优选的是使用季羟烷基铵羧酸盐作为催化剂。这种催化剂类型是热不稳定的并且允许有针对性的热失活,因此不需要在达到期望的转化率时通过计量添加潜在降低品质的抑制剂来停止三聚化。
作为催化剂,优选使用季铵盐,单独地或以混合物的形式,特别优选四烷基铵盐和/或季鏻盐,用卤素、氢氧根、醇盐或者有机或无机酸阴离子作为抗衡离子。对此的实例是:

根据本发明,所述三聚化可以分批或连续进行。优选分批方法。在分批方法中,通常在搅拌反应器中在环境压力(常压,1013毫巴)下运行,但其他压力也是可行的。在此提供94.999-5重量%的C)和5-94.999重量%的另外的易挥发二异氰酸酯A)和/或中等挥发性的二异氰酸酯B)的混合物。首先将所述二异氰酸酯的混合物预热至0-140℃,优选55-90℃,特别优选65-75℃的温度,然后将催化剂以0.001至5重量%的量计量加入,该三聚化是放热的。首先将催化剂以这样的量计量加入,以至于反应混合物的温度的明显上升5-15℃变得可识别。由于催化剂在反应过程中失活,因此反应混合物的温度在反应进程中又下降,并且可以重新进行催化剂的计量添加。重复该过程,直至达到所希望的转化率。通过分份补充加入催化剂使催化剂失活和再引发三聚的顺序允许在任何时候在转化率方面和反应的温度曲线(Temperaturprofil)方面进行最佳的工艺控制。
催化剂可以以纯的形式来使用。然而,为了更精确地计量添加和最佳混合催化剂,将催化剂溶解在合适的溶剂中是有利的。原则上,合适的是这样的溶剂,在该溶剂中催化剂具有好的溶解性,例如水、低分子量醇如甲醇或乙二醇,或低分子量有机酸例如乙酸或己酸。
连续三聚化可以在搅拌釜级联中进行。还可以想到的是搅拌釜级联和管式反应器的组合。
为了限制对于所希望的转化率而需要的催化剂量,应如此设定本发明方法的温度曲线,使得反应溶液尽可能不超过95℃的温度。
在三聚反应之后,可任选地加入催化剂毒药,但这大都是不需要的。
所产生的根据本发明的组合物除了残余单体以外还包含所使用的二异氰酸酯A)和/或B)和C)的纯的和混合的三聚物和低聚物。该混合物可以如其本身或以混合物形式作为涂料、粘合剂、密封剂或塑料配制品中的NCO组分来使用。
所述三聚化持续进行到这样的程度,以至于基于整个混合物A)+ B)+ C)计,在反应后,单体A)和/或单体B)在该混合物中的含量按绝对值计算不大于 20重量%,并且基于所使用的易挥发或中等挥发性的二异氰酸酯A)和/或B)的用量计按相对值计算不大于40重量%。
优选<10重量%的绝对值和相对<20重量%。特别优选按绝对值计算<3重量%的值和相对<6重量%。
