本发明涉及硅氧烷漆体系的不挥发的紫外稳定混合物，该混合物的紫外稳定活性结构为羟基苯并三唑，所以它们尤其适合热塑性塑料，特别是芳族聚碳酸酯的紫外稳定作用。
Description
本发明涉及硅氧烷漆体系的不挥发的紫外稳定混合物，该混合物的紫外稳定活性结构为羟基苯并三唑，所以它们尤其适合热塑性塑料，特别是芳族聚碳酸酯的紫外稳定作用。
经常要材料为提供一个保护表面以保护它们免受有害的环境影响。硅氧烷基漆已被证明特别适合于这种目的，尤其是为材料提供一种抗刮性表面。
这些漆可含有所谓的紫外稳定物质以保护漆本身和底层材料，即基体免受有害的紫外辐射。除了提供长期的紫外保护外，对这些物质的一个特别要求是它们是不挥发的，以便它们能够均匀地分布在漆层中，并且无论在固化时还是随后的使用中不会从漆层中逸出。紫外稳定物质还必须不会快速地分解，必须经久地与漆均匀相混，并且含有紫外稳定物质的漆应该是透明的。
US-A-4278804和US-A-4051161涉及了紫外稳定活性物质和含有它们的漆。但是其中公开的物质存在一些缺点，它们提供的紫外保护是不充足的，它们分解太快和/或含有该稳定剂的硅氧烷体系带有浅黄色。
US-A-5438142还公开了紫外稳定活性物质，1-(3’-(苯并三唑-2”-基)-4’-羟苯基)-1，1-双(4-羟苯基)乙烷。但是这个活性物质的缺点是不能经久地与硅氧烷基漆相混。
所以本发明的目的是提供一种不具有上述缺点的紫外稳定剂体系。
本发明通过提供含有下面通式(1)的羟基苯并三唑和可水解的含环氧基的硅烷的紫外稳定混合物达到这个目的。
R1：H、C1-C18烷基、C5-C6环烷基或C6-C12芳基，
R2：H、卤素，优选Cl、或C1-C12烷基，
R3：H、C1-C12烷基、卤素，优选Cl或Br、或C6-C12芳基，
R4：H、C1-C18烷基或C6-C18芳基。
本发明还提供紫外稳定混合物，该混合物中硅烷的环氧基与通式(1)的羟基苯并三唑的摩尔比大于2.5，优选大于4，特别优选大于16。
但是硅烷的环氧基与通式(1)的羟基苯并三唑的摩尔比不应超过200∶1。
本发明的混合物适合于硅氧烷体系，特别是抗刮和抗磨的硅氧烷涂料的紫外稳定。这种紫外稳定的涂料，优选为漆，可用作所有类制品，如木类、织物类、纸类、石类制品的涂料，但是优选作为塑料、金属、玻璃和陶瓷类制品的涂料，特别优选用于涂敷热塑性塑料类且非常特别优选用于涂敷聚碳酸酯类。
用于本发明的不挥发紫外稳定混合物的羟基苯并三唑是通式(1)的化合物。
但是优选使用1-(3’-(苯并三唑-2”-基)-4’-羟苯基)-1，1-双(4-羟苯基)乙烷(下文缩写为THPE-BZT)。THPE-BZT的生产方法详述于US-A-5438142，其中通用的合成路线公开于所述专利的图式1。该产物有Hoechst/Celanese公司的市售品。
含有环氧基团的硅烷通常是指这样的化合物，一方面它们具有至少一个环氧环同时含有在水解条件下形成硅醇结构的基团。
本发明优选采用的环氧硅烷为例如US-A-2946701所述者。它们是通式(2)或(3)的化合物：
R5是具有最多9个碳原子的二价烃基或具有最多9个碳原子的由C、H和O原子组成的二价基团，其中O原子作为醚键基团存在。R5优选-CH2OCH2CH2CH2-。
R6是具有最多4个碳原子的脂族烃基、具有最多4个碳原子的酰基或式(CH2CH2O)nZ的基团，其中n至少为1且Z为具有最多4个碳原子的脂族烃基；
m是0或1。
这些环氧硅烷的制备也描述于US-A-2946701中。所以所述专利列于此作为参考。特别优选的环氧硅烷是其中R6是甲基或乙基的那些化合物。它们都是市售品，特别是来自Union Carbide公司和HlsAG公司的产品如：
A-187或Dynasilan Glymo 3-缩水甘油基氧丙基三甲氧基硅烷
A-186 2-(3，4环氧环己基)乙基三甲氧基硅烷
紫外稳定混合物的制备
紫外稳定混合物是通过将通式(1)的羟基苯并三唑与可水解的含环氧基的硅烷均匀地混合，并加热这些混合物而制备的。加热应该在至少90℃进行至少30分钟。加热时的温度应该优选高于120℃。
已经证明采用这样的混合比是特别有利的，在这个混合比环氧基要比通式(1)的羟基苯并三唑两个自由酚羟基的等化学计量更多，所述两个酚羟基是通式(1)的羟基苯并三唑的紫外稳定作用不需要的。所以，硅烷的环氧单元与通式(1)的羟基苯并三唑的摩尔比应该大于2.5，优选大于4，特别优选大于16。
紫外稳定组分不必分开制备，以便可随后加到要被稳定的硅氧烷体系中，但也可以在合成硅氧烷体系/硅氧烷涂料时，作为一个辅助步骤被就地合成。
硅氧烷体系/硅氧烷涂料
硅氧烷体系基本上是热固化体系，它优选通过编合反应产生-Si-O-Si-链接而交联。其他的交联历程可以平行地进行。这种体系描述于例如
US-A 3 790 527，3 865 755，3 887 514，4 243 720，4 278 804，4 680232，4 006 271，4 476 281，DE-A 4 011 045，4 122 743，4 020 316，3 917 535，3706 714，3 407 087，3 836 815，2 914 427，3 135 241，3 134 777，3 100 532，3 151350，DE-A 3 005 541，3 014 411，2 834 606，2 947 879，3 016 021，2 914 427和4 338 361，并且应该认为是本公开内容的一部分。
本发明也提供根据本发明的紫外稳定的硅氧烷体系。
优选使用的硅氧烷体系是那些含有颗粒材料的体系，所述颗粒材料选自Si、Al、Sb和B以及过渡金属，优选Ti、Ce、Fe和Zr的氧化物、氧化水合物、氮化物和碳化物，并且粒度为1-100nm，优选2-50nm。
本发明的紫外稳定混合物加到硅氧烷体系中的量，相对于硅氧烷体系的固含量，应该是这样的，即相对于硅氧烷体系的固含量，羟基苯并三唑的比例为0.3-20，优选3-15，特别优选为5-10％(重量)。
有关硅氧烷基抗刮涂料体系的制备方法及其组分可以参考DE-A-2914427和DE-A-4338361，这些文献因而是本说明书的一部分。
基体，材料
含有本发明的紫外稳定混合物的硅氧烷体系可以用作本体材料和用作涂敷材料。对于选择要涂敷的基体材料没有限制。这些紫外稳定的涂料优选适合于涂敷木类、织物类、纸类、石类制品、金属、玻璃、陶瓷和塑料且特别优选用于涂敷热塑性塑料类，见述于Becker/Braun Kunststoffhandbuch，Carl Hanser Verlag，Munich，Vienna，1992。它们非常特别适合于涂敷透明的热塑性塑料，优选聚碳酸酯。
可以采用常规的涂敷方法进行涂敷，例如浸涂、溢涂、倾涂、旋涂、喷涂或刷涂。
施涂膜厚例如为2-200μm，优选2-30μm，特别优选5-15μm。基体在涂敷涂料之前可以任选用偶联剂或底涂打底。
漆优选在＞90℃温度下固化。
对本发明来说，热塑性的芳族聚碳酸酯包括均聚碳酸酯和共聚碳酸酯两者；该聚碳酸酯按已知的方式可以是线性的或支化的。
在适合的聚碳酸酯中，一部分，最多80％(摩尔)，优选20-50％(摩尔)，碳酸酯基团可被芳族二羧酸酯基所代替。这种聚碳酸酯，其中含有进入分子链的碳酸的酸根和芳族二羧酸的酸根两者，更精确地应称为聚酯碳酸酯。它们包含在术语“热塑性、芳族聚碳酸酯”的总概念中。
在过去约40年内，详细描述聚碳酸酯制备的专利已有几百篇。仅作为例子，可以参考的文献有：“Schnell，聚碳酸酯的化学和物理”，Polymer Reviews，第9卷，Interscience出版社，纽约，伦敦，悉尼1964；D.C.Prevosek，B.T.Debona ＆ Y.Kesten，企业研究中心，联合化学公司，Morristown，New Jersey07960，“聚(酯碳酸酯)共聚物的合成”发表在Journal of Polymer Science，PolymerChemistry edition，第19卷，75-90(1980)；D.Freitag，U.Grigo，P.R.Muller，N.Nouvertne’，拜尔公司，“聚碳酸酯”，聚合物科学和工程大全，第11卷，第2版1988，648-718页；最后U.Grigo博士，K.Kircher博士和P.R.Muller博士，“聚碳酸酯”，见Becker/Braun Kunststoff-Handbuch，volume3/1，聚碳酸酯，聚缩醛，聚酯，纤维素酯，Carl Hanser Verlag，Munich，Vienna，1992，117-299页。
热塑性聚碳酸酯的平均分子量
(通过测定25℃在CH2Cl2中的相对粘度确定，浓度为每100ml CH2Cl2 0.5g聚合物)为12000-400000，优选18000-80000，特别是22000-60000。
所以本发明也提供涂敷的材料，优选为聚碳酸酯且特别优选为具有抗刮涂层的聚碳酸酯。
