Abstract
本发明涉及一种无色的酮亚胺及其加合物。它们显示出卓越的色稳定性并能在可固化的涂料、浸渍剂、密封剂或粘合剂组合物中用作交联剂。这里所说的酮亚胺是一种具有伯胺基和仲胺基并在此两者之间的直链上含有至少为3个碳原子的聚胺与一种含有不多于8个碳原子并且有与羰基邻接的亚甲基的酮的加合物。本发明也涉及到制备这种酮亚胺的方法及其在可固化组合物中的应用。
Description
本发明涉及包含有一种单官能或双官能的,含一个或一个以上仲胺基的酮亚胺或其与一种能与仲胺基反应的化合物的加合物的交联剂。
这样的交联剂已为人们所熟知,并且被应用于在水分的影响下能固化的双组分组合物,例如,涂料,浸渍剂,密封剂和粘合剂中。这种组合物的主要组分是含有诸如酐基,环氧基,异氰酸酯基,乙酰乙酸酯基和α,β-烯键不饱和的羰基等官能基的树脂类。在水分影响下发生水解作用的同时释放出酮,酮从组合物中蒸发出去,而生成的伯胺基可参与到与官能树脂的交联反应。含仲胺基的酮亚胺是公知的,例如,在法国专利说明书1573546号和比利时专利说明书726331号中已作过介绍。
亦已知悉,在某些场合下使用低分子量的酮亚胺,就固化产物的毒性、炭化趋向和性能等方面来说,会引起各种问题。因而在这些场合中最好是通过使一种或多种能与仲胺基反应的化合物加到酮亚胺的仲胺基上,来提高单官能或双官能酮亚胺的分子量。这样的具有通常为300~3000的中等分子量的“低聚”酮亚胺已经,特别是在美国专利说明书3975251号、4251597号、4503174号和4504630号中已介绍过。
人们熟知的各种交联剂其颜色或者说至少其色稳定性一般均不是很令人满意的。通常,在它们的制备过程中就会发现交联剂变色,而另外一种情况是交联剂在贮存期间出现变色现象。如果上述的交联剂被用于颜色具有特殊重要性的组合物中,例如两层金属粒子层系的无色涂料,那么出现变色现象的交联剂将是不能采用的。
本发明提供的交联剂是无色的,并且显示出卓越的色稳定性。
本发明的交联剂其特征在于酮亚胺具有结构式。
其中
A代表一个饱和的、支化或非支化的、具有至多为12个碳原子而且在-NH-和-N=之间的直链中至少含有3个碳原子的二价脂族烃基
R1为具有至多为20个碳原子的烷基或环烷基,
或是-A-NH2,或是
R2为含有至多为12个碳原子的亚烷基或亚环烷基
R3为含1~4个碳原子的烷基
R4为含1~4个碳原子的烷基
n等于0,1,2,3
附有的条件是R3和R4一起不能含有多于5个的碳原子。R1最好是甲基、月桂基、十六烷基或环己基。R2的代表性例子是亚乙基、亚丙基、亚己基、亚环戊基和亚环己基或者是它们的烷基取代的衍生物。
令人吃惊的是,甚至在延长的贮存期之后,看来特选的酮亚胺不仅使其本身,也使人们乐于使用的“低聚”加合物保持无色。

适于制备本发明酮亚胺的含伯胺基和仲胺基的聚胺,在其每一伯胺基和仲胺基之间必须含有一条至少为了3个碳原子的直链。另外,也可以使用较长的和/或支化的亚烷基链。最好,伯胺基和仲胺基是通过亚丙基互连的并且在式(Ⅰ)中A代表-CH2-CH2-CH2-。可以例举的适用的聚胺有N-甲基-1,3-二氨基丙烷、N-乙基-1,3-二氨基丙烷、N-环己基-1,3-二氨基丙烷、N-甲基-1,4-二氨基丁烷、二亚丙基三胺、二(3-氨基丙烷)-1,2-二氨基乙烷和N-乙基-1,6-二氨基己烷。在式(Ⅰ)中n组R2和2组A(如果存在的话)可以是相同的或不相同的,而且均具有上述的含义。
根据本发明,在酮中的二个α-碳原子必须有二个氢原子与之相连。在式(Ⅰ)中R3和R4代表烷基,但是附有的条件是:R3和R4一起不能含有多于5个的碳原子。这样,酮的部分总共含5~8个碳原子。R3最好是代表甲基。可以例举的适用的酮有:戊酮-3、己酮-3、庚酮-3、庚酮-4、辛酮-3、辛酮-4、5-甲基庚酮-3、6-甲基庚酮-3、2-甲基庚酮-4和5,5-二甲基己酮-3。根据式(Ⅰ)双官能酮亚胺可以含有二个不同的酮亚胺基。

实施例Ⅴ
在不含颜料的无色涂料组合物中使用本发明的酮亚胺之实施例。
将化学计算量按实施例Ⅵd制备的低聚酮亚胺与含丙烯酰基树脂相混合。含丙烯酰基树脂是通过将化学计算量的丙烯酸与一种含环氧基树脂反应而制得的。含环氧基树脂的数均分子量为3500,而且它是由甲基丙烯酸缩水甘油酯、苯乙烯和丙烯酸丁酯按25∶61.5∶13.5的重量比组配而成,并且以50%(重量)的二甲苯溶液形式使用。
将此组合物敷施到钢板上形成40微米厚的涂层(在干后测得的),制得的涂层在21℃干燥一周。
其各性能指标如下:
活化期稳定性 4小时
指压干时间 30分钟
干硬时间 2小时
Persoz硬度 194秒
耐汽油性 卓越
在组合物中使用按实施例Ⅰ和实施例Ⅳa~c和实施例Ⅳe~i制备的酮亚胺来代替上文中所指的在组合物中使用按实施例Ⅳd制备的酮亚胺,也得到类似的结果。
表Ⅱ 不属于本发明的酮亚胺
