Description
技术领域
本发明涉及储存稳定的有机硅化合物组合物,其包括含有氨基的化合物,并涉及稳定有机硅化合物的方法。
背景技术
有机硅化合物,例如:基于硅烷及有机硅烷的组合物、聚硅氧烷及有机聚硅氧烷,其用途甚广,例如:作为粘着促进剂、聚合物中的交联剂、作为松脱剂、作为油漆及涂料的添加剂、用于表面的疏水化作用、包括用于纺织品、皮革及尤其建筑物及门面的保护、书籍及文物的保藏、表面性质的特殊改性,例如:玻璃纤维的涂覆、填料及颜料的硅烷化作用,以及聚合物分散液及乳液流变性能的改良。
制备具有羟基和/或烃氧基(例如:键结至硅原子的烷氧基)的硅烷和/或有机硅烷,通常使用卤代硅烷,尤其氯硅烷。由卤代硅烷与醇反应以制得烷氧基硅烷是本领域技术人员已知的且称作酯化作用。卤代硅烷、其部分烷氧基化物和/或其烷氧基硅烷在水性或酸性介质中的水解形成聚硅氧烷或有机聚硅氧烷。在三卤代硅烷与醇的反应中,由第一至第三步骤的平衡常数递减。此意谓:第三个烷氧基的引进甚为困难,或已引进的第三个烷氧基极易与卤化氢反应而形成卤代硅烷和/或卤代硅氧烷结构。这些结构是反应性的而且在加工或储存过程中实质上凝结成溶液或乳液。即使产品实施蒸馏纯化之后,残余的卤素含量,即酸性或可水解的卤化物仍留存在硅烷、有机硅烷、聚硅氧烷或有机取硅氧烷内。
例如,在储存时间内,此卤化物(Si-Hal)与硅醇基团Si-OH、大气中的水分、残余的微量水或醇反应而生成卤化氢,该卤化氢作为缩合作用催化剂可导致硅烷或聚硅氧烷的粘度增加至聚硅氧烷的凝胶化。
再者,若是具有键结至硅原子的羟基和/或烷氧基的硅烷及有机硅氧烷,缩合作用诸步骤释放出水和/或醇。若是烷氧基硅烷,微量水分即可导致不希望的硅氧烷的形成。如此则增加自由醇的不希望的挥发性有机物的比例。
目前,正致力于制备卤化物含量极低的有机硅化合物及包括有机硅化合物的产品以及以有机化合物为主要成分的组合物。尤其需要卤化物含量极低的产品。
GB 594154描述了:借助于0.05至5重量%的有机胺以稳定有机硅氧烷以防氧及热的作用。该大量胺具有缩短含有羟基和/或烃氧基的有机硅氧烷储存稳定性的效果,因为在室温下该大量胺促进这些有机硅烷的凝胶化。
EP 197540描述了:通过添加有机胺,来稳定直链型有机硅氧烷油及硫官能有机硅氧烷以防止热及(也许)高岭土的作用。
发明内容
本发明的目的是提供一种改进有机硅化合物(尤其可缩合成树脂的树脂型硅氧烷及硅烷)储存稳定性的廉价及工业上容易实施的方法,这些有机硅化合物具有键结至硅原子的羟基和/或烃氧基,
本发明提供储存稳定的有机硅化合物组合物,其包括:

(B)以有机硅化合物(A)为基准,1至499ppm重量(百万分之重量比)的含氨基化合物。
本发明是基于一项认知:在0至100℃(优选5至70℃)常用储存温度下的有机硅化合物(A),一定限量的含伯、仲或叔氨基的化合物(B)显著增加储存稳定性。若超过此量,储存稳定性再度恶化。
因此,储存期间逐渐转化为卤化氢的有机硅化合物内残余量的卤化物(Si-Hal)可用化合物(B)加以中和。含氨基化合物(B)的使用量以5至250ppm重量为佳,尤以10至150ppm重量更佳(以有机硅化合物(A)为基准)。化合物(B)的最佳数量可利用已知萃取法通过移除化合物(B)及由其形成的卤化物盐并将其加以分析而决定的。

含氨基的伯、仲和/或叔化合物(B)在氨基上具有1、2或3个有机基。例如,这些有机基可(任选)是:卤基-、三有机甲硅烷基-或氰基-取代的C1-C30烃基,其中一个或多个非相邻的亚甲基单元可由-O-、-CO-、-COO-或-OCOO-、-S-或-NH-基替代,而且其中一个或多个不相邻的次甲基单元可由-N=、-N=N-或-P=基替代。
