Abstract
本发明涉及一种生产由有机基氧基封端的有机聚硅氧烷的方法,其中,(A)羟基封端的有机聚硅氧烷与(B)具有至少两个烷氧基及含有至少一个通过二价C1-C12烃基连接到硅原子上的仲或叔氨基的基团的烷氧基硅烷,在有(C)布朗斯台德酸或路易斯酸存在的情况下进行反应,还涉及包含该反应产物并以带有有机基氧基端基的有机聚硅氧烷作为主要成分的的烷氧基室温硫化-1材料。
Description
技术领域
本发明涉及通过含有羟端基的有机聚硅氧烷与一种含仲或叔氨基的烷氧基硅烷在酸存在的情况下反应而制备含有有机基氧基的有机聚硅氧烷的方法,并涉及该反应产物作为烷氧基室温硫化-1组合物的用途。
背景技术
在本发明的正文中,有机聚硅氧烷一词包含二聚、低聚及多聚硅氧烷。
长久以来,已公知,能在无水分条件下储存的有机聚硅氧烷组合物,当有水分浸入其中时,在室温下去醇交联以得到所谓的烷氧基室温硫化-1-组合物。它们主要包含一种带有有机基氧端基的有机聚硅氧烷,和作为其它组分的带有至少三个可水解基团的交联剂、催化剂和选择性地含有添加剂。这些室温硫化-1烷氧基体系的优势是,在交联过程中,它们提供无味、中性的、生态醇作为解离产物。
带有有机基氧端基的有机聚硅氧烷是通过带有羟端基的有机聚硅氧烷与烷氧基硅烷反应而制得的。这已经在例如US-A-4942211中提及。这种方法的缺点在于该反应在室温下需几小时。该反应时间在升高温度下明显缩短,但仍是太长以致于必须等到烷氧基室温硫化-1组合物能够用所制得的具有有机基氧基端基的有机聚硅氧烷和其它组分制得。
带HO端基的有机聚硅氧烷与烷氧基硅烷在各种催化剂存在下的反应是公知的。例如在US-A-5196497中,该反应在碱金属氢氧化物存在的情况下实施。然而,该催化剂的去活化作用需要其它的反应步骤。
发明内容
本发明是用尽可能简单的方法制备室温硫化-1烷氧基组合物为目的。
本发明涉及带有有机基氧基端基的有机聚硅氧烷的制备方法,其中,
(A)带有端羟基的有机聚硅氧烷与
(B)具有至少两个烷氧基及含有至少一个通过二价C1-C2烃基连接到硅原子上的仲或叔氨基的基团的烷氧基硅烷,在有
(C)通式(IV)的酸式磷酸酯存在的情况下进行反应
(HO)aOP(-O-R7)(3-a) (IV)
其中,R7具有通式(V)
[(CR8 2)b-O]c[(CR9 2)d]0-L-M (V)
其中,R8及R9为一氢基、甲基或羟基,
b及6为2或3,
c为1至15的整数,
o为0或1,
L是一个选自由-O-、-COO-、-OOC-、-CONR2-及-CO-组成的组的基团,
M是一个非强制地由羟基、氟、氯、溴、C1-C10烷氧基烷基或氰基取代的单价C1-C20烃基,但在任一碳原子上仅有一个R8和R9基可以是一羟基,且
a表示1或2的值。
该方法即使在室温下也选择性地以极高的反应速率进行,以致于组分(A)、(B)和(C)刚混合后,就立即得到带有有机基氧基端基的有机聚硅氧烷,选择性地混入其它组分后,其就可用作烷氧基室温硫化-1组合物。
本方法的另一个优点在于没有副反应发生,例如,在线型有机聚硅氧烷上没有发现有T和Q单元形成。所生成的氨盐不必从反应产物中除去,因为它们在烷氧基室温硫-1组合物中不会引起麻烦且甚至对硫化速率有加速作用。多余的布朗斯台德或路易斯酸(C)在所制得的带有有机基氧基端基的有机聚硅氧烷中或在烷氧基室温硫化-1组合物中均不会引起麻烦。
本发明还涉及含有由上述方法制备的反应产物的烷氧基室温硫化-1组合物,其包含有作为主要成分的带有有机基氧基端基的有机聚硅氧烷。

特别优选的布朗斯台德酸(C)是通式(IV)的酸式磷酸酯
(HO)aOP(-O-R7)(3-a) (IV)
其中,R7表示C3-C50的单价烃基,该单价烃基可选择性由羟基、氟、氯、溴、C1-C10烷氧基烷基或氰基取代并能被一种基团中断、该基团能够从两边键接到碳原子上并选自由-O-,-COO-,-OOC-,-CONR2-,-NR2CO-和-CO-组成的组,且a表示1或2的值。
该通式(IV)的酸式磷酸酯的反应产物对所制得的带有机基氧基端基的有机聚硅氧烷和由它制备的烷氧基室温硫化组合物在储存期间起稳定作用。更具体地说,该烷氧基室温硫化-1组合物的皮膜形成时间实际上保持恒稳定并且抑制了脱色作用。通式(IV)的酸式磷酸酯优选具有表面活性。
C优选为1至10的整数值。L优选为-O-基。
M优选表示选择性地由C1-C10烷氧基烷基取代的C1-C20烃基。

相反,烷氧基硅烷(B)优选以相对于化学计量比过量的量添加至带有端羟基的有机聚硅氧烷(A)中。为了使带有端羟基的有机聚硅氧烷(A)与烷氧基硅烷(C)的反应进行得尽可能地完全,相对于每500重量份带有端羟基的有机聚硅氧烷(A)可优选使用1-50重量份烷氧基硅烷(B)。反应中没有反应掉的过量烷氧基硅烷(B)并不是带有机基氧基端基的有机聚硅氧烷和烷氧基室温硫化-1组合物的不利因素,所以可以保留在反应产物中。过量的烷氧基硅烷(B)能够在烷氧基室温硫化-1组合物中作为粘结促进剂。
该反应优选在20-50℃的温度下,更优选在室温下进行。根据使用的烷氧基硅烷(B),反应时间是1-10分钟。
在反应过程中反应速率一方面依赖于所用烷氧基硅烷(B)的反应活性,且另一方面依赖于酸式磷酸酯(C)的酸度。
室温下特别优选的反应时间是1-5分钟,这对于以单罐法制备室温硫化-1组合物是特别有利的。
本发明也涉及包含有由上述方法制备的反应产物并以带有有机基氧端基的有机聚硅氧烷为主要成分的室温硫化-1组合物。本发明具体地涉及包含使用通式(IV)的酸式磷酸酯制备的反应产物的烷氧基室温硫化-1组合物。
为了使最终组合物达到改善的储存稳定性,带有有机基氧基端基的有机聚硅氧烷和由其制备的烷氧基室温硫化-1组合物能够被支化羧酸的金属盐稳定,如US-A-4942211中所述。
除了上述的组分外,该烷氧基室温硫化-1组合物还能够包含其它公知组分。
其它能够在烷氧基室温硫化-1组合物的制备过程中优选一同使用的物质是通式(VI)的硅烷或它们的部分水解产物,

其中,R10和R11表示选择性地由氟、氯、溴、C1-C4烷氧基烷基或氰基取代的C1-C13单价烃基,且u为0,1或2。
R10和R11的优选含义与上面R相同。
通式(VI)的硅烷的部分水解产物是,例如六甲氧基二硅氧烷和六乙氧基二硅氧烷。
能够在烷氧基室温硫化-1组合物的制备过程中优选一同使用的其它物质是双(三烷氧基硅基)C1-C13烷烃,其中烷氧基具有与OR11相同的含义,例如双(三乙氧基硅基)乙烷。
在制备烷氧基室温硫化-1组合物时,亦可使用缩合催化剂、增强型填料、非增强型填料、颜料、可溶性染料、香料、增塑剂例如以三甲基硅氧烷基封端的在室温下呈液态的聚二甲基硅氧烷或磷酸酯、杀菌剂、树脂状有机聚硅氧烷类(包含由(CH3)3SiO1/2单元及SiO4/2单元组成者),纯有机树脂,例如:丙烯腈、苯乙烯、氯乙烯或丙烯的均聚物或共聚物(其中此类纯有机树脂,尤其是苯乙烯与丙烯酸正丁基酯的共聚物,可在每个终端单元具有与Si-键结羟基的二有机聚硅氧烷存在的情况下,通过上述单体的自由基聚合作用以制得),防腐剂、聚乙二醇(可以是已被酯化或醚化)、抗氧剂、热稳定剂、溶剂、影响电学性能的品剂(例如:导电性炭黑)、阻燃剂、光稳定剂及皮膜形成时间延长剂(例如:具有SiC-键结氢硫基烷基硅烷),以及发泡剂(例如:偶氮二甲酰胺)。其他可添加的物质是:粘结促进剂,优选氨基官能硅烷。
优选使用缩合催化剂。根据本发明,该烷氧基室温硫化-1组合物可能包括任何所需的缩合催化剂,目前凡除水后即可长期储存且于室温下遇水即实施交联生成弹性体的组合物中均含有缩合催化剂。
此类缩合催化剂的实例是:锡、锌、锆、钛或铝的有机化合物。在该缩合催化剂中,优选的是:钛酸丁基酯及有机锡化合物,如二乙酸二正丁基锡、二月桂酸正丁基锡、二有机锡二有机酸盐(酯)或它们的低聚物与一种硅烷的反应产物,该硅烷的每个分子具有至少两个可水解的单价烃基,该烃基经由氧与硅键结,且必要时由烷氧基取代,该反应产物内锡原子的价位,由≡SiOSn≡基中的氧原子及/或SnC-键结的单价有机基中获得满足。
该烷氧基室温硫化-1组合物优选包含有填料。填料的实例是:非增强型填料,亦即BET表面积最高为50m2/g的填料,例如:石英、硅藻土、硅酸钙、硅酸锆、沸石、金属氧化物粉末,例如:氧化铝、氧化钛、氧化铁或氧化锌及/或该氧化物的混合物,硫酸钡、碳酸钙、石膏、氮化硅、碳化硅、氮化硼、玻璃粉及塑料粉,例如:聚丙烯腈粉;增强型填料,亦即BET表现积超过50m2/g的填料,例如:热解二氧化硅、沉淀二氧化硅、碳黑,例如:炉黑或乙炔黑,及高BET表面积的硅铝混合氧化物;及纤维型填料,例如:石棉及合成聚合物纤维。
上述填料可经疏水化处理,例如:用有机硅烷及/或硅氧烷或用硬脂酸加以处理,或将羟基加以醚化生成烷氧基。可使用单独一种填料或至少两种填料的混合物。
空气中通常含有的水分即足以使烷氧基室温硫化-1组合物实施交联作用。必要时交联作用亦可在低于或高于室温的温度下实施,例如:-5至10℃,或30至50℃。
所以本发明的烷氧基室温硫化-1组合物极适宜用作例如接缝(包含垂直接缝)、或用作类似狭缝例如建筑物、车辆、船舶或飞机等宽达10至40毫米的内部间隙的密封组合物,或例如在建造门窗、制造展示橱柜中用作粘结剂或油灰,以及用以制造保护性涂料、橡胶弹性异型制品,电机或电子设备的绝缘材料。
