Description

玻璃板
技术领域
本发明涉及玻璃板，并且具体但不排它地涉及日光控制和/或低发射率的玻璃板和/或在向玻璃基底施加涂层叠层形式的滤光片之后可经受热处理的玻璃板。本发明更具体地涉及通过真空沉积技术，例如通过溅射或磁控溅射将涂层叠层施加到玻璃上的情况。
背景技术
当设计用于玻璃应用的涂层叠层时，必须考虑多种因素。这些因素不仅包括涂覆的玻璃板的所希望光-能量性能，而且还包括例如涂层叠层的耐磨性(以便于处理、运输和加工)、涂层叠层的稳定性和化学耐久性(以便于在各种条件下储存)以及制造工艺控制的容差(以促进可接受的生产率和产品批次之间的一致性)。
尤其是在试图增加涂层叠层的耐磨性和/或化学耐久性时，已知会施加顶涂层到涂层叠层上。GB2,293,179涉及用于提高涂覆的基底的化学和机械耐久性同时使光学性质的任何相应变化最小化的保护性附加层。这种保护性层由硅的氧化物或氧氮化物形成，或者由硅的氧化物、氮化物和氧氮化物中的一种或多种的混合物形成，并且具有10～100的厚度。
但是我们已经发现，如GB2,293,179中所述的这种保护性附加层，当沉积在某些涂层叠层上时，例如沉积在“基本上由至少一种选自钛、氧化钛和氮化钛的材料组成的基础抗反射层/红外反射层/顶部抗反射层/顶涂层”类型的涂层叠层上时，在运输过程中并不总是提供良好的耐性，并且在涂层的表面可能出现划痕。当涂覆的玻璃板在其运输后进行热处理时，划痕变得更多和更明显。“运输”在本文中是指例如通过卡车成堆地或成箱地从例如涂布机传送到批发商或变换器(transformer)或钢化炉。
发明内容
本发明提供如独立权利要求所定义的玻璃板、制造玻璃板的方法和顶涂层的用途。从属权利要求中限定了优选的实施方式。
本发明可提供良好的机械耐性(尤其是在运输过程中良好的耐刮擦性)、可热处理性、化学耐久性、防潮性和制造参数稳定性的有利组合。
顶涂层可有利地为至少两个子层的组合：第一顶涂层子层被认为尤其提供在热处理玻璃板时有用的“保留区(reserve)”，以保证在热处理过程中对涂层叠层的其它部分的热保护；并且第二顶涂层子层被认为尤其提供对涂覆的玻璃板的机械保护。
已经发现有利的是，顶涂层包括第一顶涂层子层，其在第二顶涂层子层的下面，基本上由至少一种选自钛、氧化钛和氮化钛的材料组成。本发明的第一顶涂层子层的一个优点是：它可为玻璃板提供在储存过程中(例如在热处理和/或装配之前)特别好的化学耐久性，便于控制制造容差和生产工艺。这可与在热处理过程中为涂层叠层的其它部分提供热保护的能力相结合。优选地，第一和第二顶涂层子层彼此直接接触，但在其它实施方式中，它们之间可存在另外的子层。仍然优选地，顶涂层由两个顶涂层子层组成。但是，在一些实施方式中，顶涂层可包括另外的子层，例如在第一顶涂层子层之下。
第一顶涂层子层可包括除上述那些材料以外的材料，例如它可由以下材料组成、包括以下材料或基于以下材料：
■Ti、Zr、Hf、V、Nb、Ta、Cr或它们的混合物或这些金属中的至少一种与A1和/或B的混合物或者
■Ti、Zr、Hf、V、Nb、Ta、Cr的氧化物、亚化学计量氧化物、氮化物或氧氮化物，或它们的混合物，或者为这些金属中的至少一种与A1和/或B的混合物的氧化物、亚化学计量氧化物、氮化物或氧氮化物。
第一顶涂层子层可具有

的几何厚度，优选

或

Figure S05841250920070604D000026
。至少
Figure S05841250920070604D000027
的厚度可避免当热处理玻璃板时的损害，不大于，优选或
Figure S05841250920070604D000033
的厚度可避免涂覆的玻璃板的透光率的过大下降。
第二顶涂层子层可基本上由氧化硅、氮化硅、氧氮化硅、碳化硅、碳氮化硅、氧碳化硅或氧碳氮化硅组成。优选地，该层通过真空沉积技术，尤其是磁控溅射来沉积。如本领域中众所周知的，用来沉积这种层的靶可由纯Si或掺杂有例如A1(例如Si靶中8％的Al)、Zr、Ti、NiCr、Ni、B或Sb中的一种或多种的Si制成。因此第二顶涂层子层可结合相对少量的这种掺杂剂而不偏离本发明。也可使用SiC靶，如Carborundum公司的靶FG90。
第二顶涂层子层的几何厚度有利地为

，优选
Figure S05841250920070604D000035
还更优选
Figure S05841250920070604D000036
。当小于
Figure S05841250920070604D000037
时，第二顶涂层子层不能足够厚以保护涂层叠层例如在运输过程中不被刮擦。而且，当涂覆的玻璃板在其形成之后或在其形成和运输之后被热处理时，我们发现，大于
Figure S05841250920070604D000038
的第二顶涂层子层的厚度会导致不能接受的划痕。在涂覆的玻璃板热处理后出现的这些最后的划痕看起来实际上是“枝状晶体”，从而显示出当进行热处理时涂层中的脆性区域，即涂层本身的薄弱之处。这种枝状晶体看起来沿着在热处理之前已经进行机械接触的路径形成，在宏观上显示为“划痕”，这使得玻璃板不可用。当第一顶涂层子层由Ti或其上述化合物之一组成，包括或基于Ti或其上述化合物之一时，第二顶涂层子层的几何厚度有利地为
Figure S05841250920070604D000039
，优选
Figure S05841250920070604D0000310
优选地，当第二顶涂层子层基本上由氧化硅组成时，这种氧化物被完全氧化；这可给涂层叠层提供光学优点，完全氧化的氧化硅的层对例如整个涂层叠层的颜色具有较小影响。可选择地，第二顶涂层子层可基本上由亚化学计量氧化硅组成。
优选地，第二顶涂层子层暴露于空气中，也就是说，其为涂层叠层的最外层。这可在机械耐性和可热处理性方面提供特别良好的结果。
还可以在没有第一顶涂层子层的情况下使用第二顶涂层子层。
在优选实施方式中，顶涂层包括基本上由氮化钛组成的几何厚度为20～40
Figure 2005800412509100002S05841250920070604D00001142139QIETU
的第一顶涂层子层，以及基本上由氧化硅组成的几何厚度为
Figure S05841250920070604D000041
的第二顶涂层子层。
可由本发明提供的性质的组合具有与可热处理的和热处理过的玻璃板相关的特定优点。不过，本发明也可用于不被热处理的玻璃。这里所用的术语“可热处理的玻璃板”指的是：带有涂层叠层的玻璃板适合于进行弯曲和/或热钢化和/或热硬化操作和/或其它热处理工艺，而这样处理过的玻璃板的雾度不超过0.5，优选雾度不超过0.3。这种热处理工艺可涉及到在大气中将带有涂层叠层的玻璃加热到或暴露于大于约560℃的温度，例如560℃～700℃。其它的这种热处理工艺可以是陶瓷或搪瓷材料的烧结、双玻璃单元的真空密封和湿涂覆的低反射性涂层或防闪光涂层的煅烧。该热处理工艺，尤其当其为弯曲和/或热钢化和/或热硬化操作时，可以在至少600℃的温度下进行至少10分钟、12分钟或15分钟，至少620℃下进行至少10分钟、12分钟或15分钟，或者至少640℃下进行至少10分钟、12分钟或15分钟。
涂层优选通过真空沉积技术，尤其是磁控溅射来沉积。
本发明的玻璃板可包括一个或多个红外反射层。可由例如银制成的这些层用来反射入射的红外辐射。夹住红外反射层的介电抗反射层用来减少光谱可见光部分的反射，否则银层会引起这种反射。
每个抗反射介电层可由单层组成，或者可包括两个或多个子层，这些子层一起形成抗反射介电层。抗反射介电层或者至少部分抗反射介电层可包括氧化物，例如包括锌和锡和/或锌和铝的氧化物。
涂层叠层可包括在红外反射层之下和/或之上的一个或多个阻挡层，这是本领域众所周知的。可使用例如以下材料中的一种或多种材料的阻挡层：Ti、Zn、Cr、“不锈钢”、Zr、Nb、Ni、NiCr、NiTi、ZnTi和ZnAl。这种阻挡层可以以金属层、低价氧化物(即部分氧化的层)或完全氧化的氧化物的形式沉积。可选择地，也可使用氮化阻挡层。每个阻挡层可由单层组成，或可包括两个或多个子层，这些子层一起形成阻挡层。阻挡层可包括基本上金属形式的第一阻挡层，例如包括镍和铬，以及与第一阻挡层组成不同(例如包括钛)的位于上面的第二阻挡层，其为选自氧化物、亚化学计量氧化物、氮化物、亚化学计量氮化物、氧氮化物和亚化学计量氧氮化物的形式。
在本发明的一种实施方式中，第二顶涂层子层可具有的几何厚度，优选
Figure S05841250920070604D000052
，或者还更优选约
Figure S05841250920070604D000053
。令人惊奇地发现，这种范围的厚度可提供良好的机械性质，并且可减少或避免在玻璃板热处理之后出现划痕。但是，这种厚度会增加生产成本，并且也会必须要再检查整个涂层叠层，例如在层厚度方面，以避免例如颜色变化。
我们已经注意到，模拟涂覆的玻璃板在被运输时所经历的过程的最佳工具是Automatic Web Rub Test(AWRT)。将覆盖有棉布的活塞(标号：由ADSOL供应的CODE40700004)被放置与涂层接触，并在表面上振动。活塞带有砝码，以具有作用在17mm直径指状物上的33N的力。在一定数量的循环之后，棉布在涂覆的表面上的磨耗将损害(除去)涂层。该试验用来定义涂层脱色(除去顶层)之前和涂层中出现划痕之前的阈值。在样品上分开的距离处进行该试验10、50、100、250、500和1000次循环。在人工天空(artificial sky)下观察样品，以确定在样品上是否能看见脱色和/或划痕。AWRT分数代表不引起降级或者引起非常轻的降级(在均匀的人工天空下离样品80cm距离处用裸眼看不见)的循环次数。分别根据出现轻微划痕或者根本没有出现划痕，在AWRT分数后面标出“-”或“+”。优选地，本发明的玻璃板显示至少250的AWRT值，更优选至少500。
本发明的玻璃板的涂层叠层可以是这样的：如果施涂到4mm玻璃的透明片材上，它将给出大于约25％、30％、35％、40％、45％、55％、60％、65％、70％、75％、80％、85％或90％的用发光物C测定的TL。热处理可引起玻璃板的透光率(TL)增加。这种TL的增加在确保TL对于玻璃板足够高以用于高透光率的玻璃方面可能是有利的，例如在车辆的挡风玻璃或者建筑应用中，在这些应用中期望单一(monolithic)涂覆的玻璃板具有大于约25％、30％、35％、40％、45％、55％、60％、65％、70％、75％、80％、85％或90％的TL，或者在双玻璃单元中，其中期望双玻璃单元具有大于约55％、60％、65％、70％、75％、80％或85％的TL。在热处理过程中TL的绝对值(absolute term)可增加例如大于约2.5％、大于约3％、大于约4％、大于约6％、大于约8％或大于约10％。
本发明的玻璃板可适合于在双玻璃单元中装配。它们可适于例如在位置3(内玻璃片材的内表面)或位置2(外玻璃片材的内表面)处具有涂层叠层的双玻璃单元中装配。形成双玻璃单元的玻璃板的至少之一在其装配在双玻璃单元中之前可被热处理。
具体实施方式
下面将仅通过实施例和对比例进一步描述本发明的实施方式。
根据下面的表，涂层叠层已经通过磁控溅射沉积在玻璃基底上。涂层叠层全部被描述为是它们从磁控溅射涂布机中退出的状态。除了实施例9中玻璃厚度为2.6mm之外，对于所有实施例，玻璃厚度为6mm。在其它厚度例如4mm的玻璃上预计得到类似的结果。
在实施例1～6和11以及对比例1～11中，除了顶涂层，涂层叠层总是相同的。抗反射层包括各种比例的锌和锡的混合氧化物：Zn(50)Sn(50)Ox表示包括50％锌和50％Sn的混合氧化物，Zn(90)Sn(10)0x表示包括90％锌和10％Sn的混合氧化物。实际上，用来得到Zn(50)Sn(50)Ox层的靶的准确组成是Zn：52％Sn：48％，以这些金属在靶中的重量计。它对应于可以容易地形成锌锡酸盐的组成，本领域中已知它在热处理过程中的阻滞性质。
对比例1和2说明，包括单个TiN子层的顶涂层在AWRT试验中显示出差的结果，甚至当TiN子层的厚度较高时，涂层在小于50次循环之后变差。
对比例3～7和实施例1～3说明在TiN第一顶涂层子层上添加SiO2第二顶涂层子层，该SiO2子层显示出不同的厚度。对比例3表明，添加
Figure S05841250920070604D000061
的SiO2顶涂层子层在AWRT试验中不提供更好的结果。而实施例1～3和对比例4～7显示出类似或良好的AWRT结果，其中SiO2顶涂层子层为
Figure S05841250920070604D000062
。然而这些涂层叠层被热处理，例如被钢化的能力彼此不同，在钢化之后没有显示出划痕。对比例4～7(其中SiO2厚度为36～
Figure S05841250920070604D000071
)在钢化之后以及在运输(用AWRT试验模拟的)和钢化之后都显示出划痕。然而实施例1、2和3(其中SiO2厚度为15、25和
Figure S05841250920070604D000072
)提供对AWRT试验的良好耐性的优点，因此对运输有良好耐性，并且在钢化之后不显示划痕。因此作为本发明一部分的这些实施例是提供良好机械耐性的涂层，例如对运输的良好耐性，具有可热处理的优点。参考实施例3，注意到由于SiO2厚度较大，相比于没有SiO2子层的涂覆的玻璃板，可能会出现颜色变化。这可通过调节形成涂层叠层的其它层的厚度来修正，而不损害具有SiO2顶涂层子层的涂层叠层的良好机械耐性和可热处理性的优点。
对比例8、9和11说明TiN第一顶涂层子层确保涂覆的玻璃板的良好可热处理性和稳定性的优点。
对比例10说明在TiN第一顶涂层子层上按顺序具有SiO2第二顶涂层子层的优点。
实施例4、5和6说明本发明的其它实施方式：Ti第一顶涂层子层或SiC第二顶涂层子层。实施例4显示出在热处理之前82％的透光率，0.070的发射率和6Ω/□的电阻，在热处理之后89％的透光率，0.045的发射率和4.5Ω/□的电阻。实施例6显示出在热处理之前78％的透光率和热处理之后89％的透光率。实施例11说明Zr第一顶涂层子层。
实施例7～9说明本发明应用到双银涂层叠层，具有不同的第一顶涂层子层，即TiN、Ti、TiO2。实施例7和8是提供高选择性的可热处理的涂层；它们显示出在钢化之前74％的透光率和钢化之后81％的透光率，0.018的发射率和1.6Ω/□的每平方的电阻。实施例9的玻璃板可用于制造汽车用可加热的日光控制挡风玻璃。这种挡风玻璃显示出在发光物A下77％的透光率，44％的能量透过率和2.2Ω/□的每平方的电阻。
实施例10是本发明的玻璃板(玻璃片材带有实施例1的涂层叠层，所不同的是SiO2厚度为)和不是本发明的玻璃板(玻璃片材带有对比例2的涂层叠层)的运输试验。使所有这些玻璃片材经过以下步骤：
■将玻璃片材聚集成每个2.5T的堆，在玻璃片材之间有每m2玻璃200mg的层间粉末。
■3个月库存之后运送
■装载在卡车中，堆之间有卡纸板隔片
■在垫子中压力为4巴
■大于1000km的路程，穿过阿尔卑斯山脉，这是临界情况，因为道路弯曲并且温度急剧变化
■在聚光灯下检查玻璃片材：与没有SiO2顶涂层子层的玻璃片材相反，具有SiO2顶涂层子层的玻璃片材有良好的结果(没有划痕，没有脱色)
■返回到出发点，重新检查，具有SiO2顶涂层子层的玻璃片材总是有良好的结果
■玻璃片材被涂覆之后6个月，将如上所述已经旅行的具有SiO2顶涂层子层的玻璃片材运送到钢化炉中
■搬运、切割、加工玻璃片材
■钢化
■在炉出口，裸眼看不见机械缺陷。
