Abstract
具有涂层叠层的玻璃板，该涂层叠层依次至少包括底部抗反射层，红外反射层，顶部抗反射层和包含至少一种选自如下材料的顶涂层：周期表IVb，Vb和VIb族元素的氮化物，氧氮化物，碳化物，氧碳化物和碳氮化物。
Description
本发明涉及玻璃板且特别地，但并非专门涉及日光控制和/或低辐射率的玻璃板，计划在向玻璃基底实施涂层叠层形式的滤光片之后对该玻璃板进行热处理。
本发明更具体涉及通过真空沉积技术将涂层叠层用于玻璃的情况，真空沉积技术例如溅射或磁控溅射。
设计用于玻璃应用的涂层叠层时，必须考虑多种因素。这些不但包括涂覆玻璃板期望的光-能量特性，而且包括例如涂层叠层的耐磨性(以便处理和加工)，涂层叠层的稳定性和化学耐久性(以便在各种条件下存贮)和加工过程的控制公差(以促进容许的生产率和制品批次之间的一致性)。
已知向涂层叠层上实施顶涂层特别是为了提高该涂层叠层的耐磨性和/或化学耐久性。在这方面已提出使用金属层(例如铬，镍铬或锌)或电介质层(例如氧化钛，氧化硅，氧化锌，氮化硅，氮化铝)。然而，许多已知的非金属顶涂层会受到不足的化学耐久性的影响，同时已知的金属顶涂层可能具有许多缺点。
本发明提供了玻璃板，制造玻璃板的方法和顶涂层的用途，如在独立权利要求中所限定的。从属权利要求中说明了优选的实施方案。
本发明可以提供以下良好性质的有利组合：
化学耐久性，特别是顶涂层包含氮化物或氧氮化物时
防潮性能，特别是当顶涂层包含氮化钛时
加工参数的稳定性
可热处理性
顶涂层优选是涂层叠层最外部的暴露层。
优选通过真空沉积技术，特别是磁控溅射沉积该涂层。
本发明的顶涂层的一个优点可能是存贮期间例如热处理和/或安装之前特别良好的化学耐久性与便于控制制造公差和生产工艺的组合。与此结合的，还能够在热处理期间向涂层叠层的其它部分提供热防护。对于已知的金属顶涂层：
金属顶涂层厚度的微小变化会显著影响热处理涂层玻璃板的性质和/或必须使用的热处理条件，特别是如果在热处理期间该金属相对难于氧化。
如果使用高活性的金属，这时在玻璃板热处理之前的存贮期间该金属会在空气中部分氧化。由于氧化取决于环境温度，湿度和其它存贮条件，甚至取决于玻璃板在真空镀膜线出口处首次进入大气时玻璃板的温度(对于较厚的基底玻璃板的温度通常较低)，因此氧化的程度可能难于控制。
因此，可能难于控制所得的待热处理中间涂覆玻璃板的制造公差和精确状态。热处理之前和之后金属顶涂层在折射率和/或消光系数上的显著差异还可能使得厚度和热处理条件的控制变得重要以便避免热处理玻璃板性质无法接受的变化，例如透光率，能量透过滤和颜色。
本发明顶涂层厚度的制造公差的精细调节和控制对玻璃板性质的变化可能不大重要；这有利于更高的生产量和/或处理量.此外，当本发明的顶涂层的折射率和/或消光系数在热处理之前和之后相当近似时(例如由于热处理造成的550nm的折射率的变化小于1，0.8，0.6，0.5，0.4，0.3或0.2和/或由于热处理造成的550nm的消光系数的变化小于1.5，1.4，1.3，1.2，1，0.8，0.6，0.5，0.4，0.3或0.2)，作为制造公差和热处理之前的存贮时间和中间制品状态的函数，一个或多个性质例如透光率，能量透过率，光反射，反射光颜色，透射光颜色的容许误差可能不易发生显著变化.本发明还有利于在不同厚度(例如2mm，4mm，6mm，8mm的玻璃片)的玻璃基底上使用基本相同的涂层叠层，这些玻璃基底的适当热处理需要不同的条件.
根据本发明的某些实施方案，使用氮化物或氧氮化物顶涂层可能有利于沉积的控制；当用于制造玻璃板的真空镀膜机与大气接触以进行维护并且必须清除空气和/或水蒸气污染时特别如此。如果空气是约80％的氮气，空气污染对这些材料的沉积可能破坏较小。对于含活性氮气和/或氧气气氛中的沉积，空气和水蒸汽污染的影响不如用于沉积金属层的惰性气体(例如氩气)溅射气氛中的相当的杂质显著，在后一情形中，该杂质是存在于沉积气氛中的唯一活性物质。
当玻璃板承载具有单一银金属层或其它反射红外线的金属层并具有例如下列结构的涂层叠层时：
玻璃
底部抗反射电介质层
可选的成核或阻挡层
红外反射金属层
可选的阻挡层
顶部抗反射电介质层
顶涂层
该底部抗反射电介质层优选具有50nm至80nm的光学厚度，同时顶部抗反射电介质层和顶涂层的组合优选具有50nm至100nm的光学厚度。
当玻璃板承载的涂层叠层具有双重银金属层或其它反射红外线的金属层并且具有例如下列结构时：
玻璃
底部抗反射电介质层
可选的成核或阻挡层
红外反射金属层
可选的阻挡层
中间抗反射电介质层
可选的成核或阻挡层
红外反射金属层
可选的阻挡层
顶部抗反射电介质层
顶涂层
该底部抗反射电介质层优选具有35nm至80nm的光学厚度，中间抗反射电介质层优选具有130nm至180nm的光学厚度并且顶部抗反射电介质层和顶涂层的组合优选具有40nm至80nm的光学厚度.
该顶涂层可以具有大于或等于或的几何厚度；它可以具有小于或等于或的几何厚度。该顶涂层优选具有15至
的几何厚度，特别地，当它包含钛的氮化物或氧氮化物时更优选为20至这样的厚度可以最好地提供所需的耐腐蚀性同时所提供的该顶涂层在热处理之后可提供需要的特性，例如折射率和/或消光系数。
如本领域中所已知的，该过滤叠层可以包含一个或多个在红外反射层之上和/或之下阻挡层。这一个或多个阻挡层可以使用下列一种或多种材料，例如：Ti，Zn，Cr，“不锈钢”，Zr，Nb，Ni，NiCr，NiTi，ZnTi和ZnAl。可以以金属层或低氧化物(即部分氧化的层)沉积这种阻挡层。或者，也可以使用氮化的阻挡层。每个阻挡层可以由单层组成或者可以包含两个或多个亚层，这些亚层共同形成该阻挡层。该阻挡层可以包含主要为金属形式的第一个阻挡层，例如包含镍和铬，以及与第一个阻挡层组成不同的上部第二个阻挡层(例如包含钛)，第二个阻挡层可以是选自如下的形式：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。
每一个抗反射电介质层可以由单层组成或者可以包含两个或多个亚层，这些亚层共同形成该抗反射电介质层。顶部抗反射电介质层，或至少部分与顶涂层接触的顶部抗反射电介质层可以是不同于氮化硅和/或不同于氮化铝的材料；它可以包含氧化物，例如包含锌和锡和/或锌和铝的氧化物。
本发明对于如下的玻璃板具有特别的效用，
该玻璃板热处理后反射光带有颜色，使得：
a*在+2和-10之间，优选在0和-7之间；且
b*在+2和-15之间，优选在0和-10之间；
或者该玻璃板
当热处理或者与透明玻璃片组装成双层玻璃单元，并且涂层位于双层玻璃单元内侧的位置2(外玻璃片的内表面)或位置3(内玻璃片的内表面)时，将使从外部观察的反射光带有颜色，使得：
a*在0和-7之间，优选在0和-4之间；且
b*在+2和-10之间，优选在0和-7之间。
优选地，当进行热处理并以单片玻璃的形式和/或以组合双层玻璃单元的形式存在时，该玻璃板可提供基本为中性色的反射。
对于可热处理和热处理的玻璃板，通过本发明提供的特性组合具有特殊的优点。然而，对于未进行热处理的玻璃也可以使用本发明。这里所使用的术语“可热处理的玻璃板”是指载有涂层叠层且适合于进行弯曲和/或热钢化和/或热硬化操作同时如此处理的玻璃板的雾度不超过0.5，且优选不超过0.3的玻璃板。这里使用的术语“基本无雾度热处理玻璃板”是指已经弯曲和/或热钢化和/或热硬化并且雾度度不超过0.5且优选不超过0.3的玻璃板。该热处理可能涉及将玻璃板的温度提高到超过400℃，450℃，500℃，550℃，600℃，650℃或700℃的温度。
热处理可以引起玻璃板透光率(TL)的提高.TL的这种提高可有利于确保TL足够高以便在高透光玻璃中使用该玻璃板，例如用于车辆挡风玻璃或建筑应用中，其中希望单层涂覆的玻璃板具有大于约55％，60％，65％，70％，75％，80％，85％或90％的TL，或者用于双层玻璃单元中，其中希望该双层玻璃单元具大于约55％，60％，65％，70％，75％，80％或85％的TL.在热处理期间TL的绝对值(absolute term)的增加可以大于例如约2.5％，约3％，约4％，约5％，约8％或约10％。
本发明的玻璃板的涂层叠层可以是这样的，如果实施到4mm的透明玻璃片上，它可以提供大于约55％，60％，65％，70％，75％，80％，85％或90％的以透明度C度量的TL和/或大于约35％，40％，50％，55％或60％的能量透过率(TE)(System Moon 2)。该涂层叠层可能造成该玻璃板的TL降低10至20％。该玻璃板的能量透过率(System Moon 2)可以大于40％，45％，50％，55％，60％或65％。当希望将该玻璃板用于低辐射率用途时，这样的性质或性质组合可能特别有用。
本发明的玻璃板的涂层叠层可以是这样的，如果实施到4mm的透明玻璃片，它可以提供这样的以透明度C度量的TL和(TE)(SystemMoon 2)组合：
TL大于或等于70％且TE小于或等于50％；或者
TL大于或等于60％且TE小于或等于42％；或者
TL大于或等于50％且TE小于或等于35％；或者
TL大于或等于40％且TE小于或等于30％。
当希望将玻璃板用于日光控制用途时，这样的性质组合可能有用。
在空气中存贮时，例如在预定的热处理之前，本发明的顶涂层可能发生某些变化或氧化，例如，当初始以氮化钛或氧氮化钛的形式沉积顶涂层时，与空气接触的顶涂层的至少表面部分在存贮期间可能氧化成氧化钛。本发明的其它顶涂层可能发生类似的效果。
现在将参照图1和图2描述本发明的实施例，该图是弯曲和钢化处理之前玻璃板的横截面(为了便于说明，未按比例显示玻璃板和涂层的相对厚度)。
实施例1
图1显示了单一Ag层，可热处理，通过磁控溅射沉积在玻璃基底上的涂层，并且该涂层具有如下顺序的结构：
在这种类型的结构中，Ag层起到反射入射红外辐射的作用并且为了实现这个作用必须保持为银金属而非氧化银并且不能被相邻的层污染。中间夹有Ag层的介电抗反射层用于减少Ag层可能另外引起的可见光的反射。热处理阻挡层用于在玻璃板热处理期间防止Ag层退化(degradation)的作用；该过程中它通常会至少部分氧化。沉积阻挡层用于在上层介电抗反射层溅射期间防止该热处理阻挡层在氧化气氛中的氧化；在这个过程中该阻挡层会被至少部分氧化。
热处理加工之前和之后玻璃板的性质：
| 性质 | 热处理之前<sup>参见下注1</sup> | 热处理之后<sup>参见下注2</sup> |
| TL(透明度C) | 77％ | 87％ |
| TE(System Moon 2) | 57.5％ | 67％ |
| 雾度 | 0.08 | 0.16 |
| a<sup>*</sup>反射系数 | -4(涂层侧) | -3(涂层侧) |
| b<sup>*</sup>反射系数 | -17(涂层侧) | -12(涂层侧) |
| RE(System Moon 2) | 20％(涂层侧) | 22％(涂层侧) |
注1：对具有涂层的单层玻璃板在热处理之前进行测量
注2：在680℃(炉温)下钢化热处理8分钟后进行测量。热处理优选使氮化钛顶涂层基本上完全氧化。
由于它们提供了中性的反射外观，实施例的色彩坐标(coordinate)特别适合于建筑双层玻璃单元。
在钢化之前，对依照实施例1的试样进行耐ClevelandCondensation试验和Climatic Chamber试验(耐循环凝结测试)
Cleveland试验包括在恒温下使涂覆玻璃与饱和水汽气氛接触。在试样上不断形成凝结，正是这种凝结可能引起表面的退化。测试箱(cleveland)置于环境温度为23℃±3的房间中。谨慎操作以便确保气流和太阳辐照不干扰测试箱。将试样安置到构成测试箱顶部的支架中。测试箱的底部充当水量的容器。仅通过使用热偶控制的加热电阻加热底部的软化水来调整测试箱，保持50℃±2的水温。对试样进行测试24小时。
Climatic Chamber试验包括将试样与相对湿度维持在98％的气氛接触，并进行连续循环a)一小时内将温度从45℃提高到55℃和b)随后在一小时内将温度从55℃降低到45℃。重复进行该循环三天。可以在500升的Weiss室中进行该试验。
对进行了每项测试的试样进行检查：a)针状小缺陷(直径＜0.5mm)，有限密度的该缺陷是可接受的；b)大缺陷例如直径为数mm的腐蚀点，该缺陷是不可接受的；c)涂层的溶解，这是不可接受的。
得到如下结果：
| 试验 | 实施例1 | 没有实施例1的顶涂层的对照实施例 |
| Cleveland | 无变化 | 多于每dm<sup>2</sup>20个点，其中一些的直径大于1mm |
| Climatic Chamber | 直径小于0.5mm的点少于每dm<sup>2</sup>3个 | 多于每dm<sup>2</sup>20个点，其中一些的直径大于1mm |
| 适于长期存贮 | 是 | 边界 |
据期望实施例1的变化在Cleveland和Climatic Chamber试验中将具有相似的性能，其中顶涂层材料选自权利要求所定义的方案。
也可以将实施例1中所用的涂层叠层用于厚度为4mm，6mm和8mm的其它玻璃薄片。在进行钢化之前这些薄片被存贮在不同条件中并且持续时间也不同(6mm的试样持续1个月，4mm的试样持续3个月，8mm的试样持续5个月)然后组装成双层玻璃单元。这些玻璃的典型性能为：
| 玻璃厚度 | TL(M) | L(M) | a(M) | b(M) | R(M) | L(DV) | a(DV) | b(DV) |
| 4mm | 88.0 | 24.4 | -1.6 | -8.6 | 3.5 | 34.8 | -1.4 | -4.0 |
| 6mm | 87.8 | 23.1 | -1.3 | -8.9 | 3.7 | 34.0 | -1.2 | -4.2 |
| 8mm | 86.4 | 23.3 | -1.6 | -9.4 | 3.6 | 34.0 | -1.2 | -4.0 |
其中L，a和b是Hunter坐标上的色彩坐标，R是每平方的电阻，(M)代表从涂层侧即位置1处涂层测得的钢化的单层玻璃的性质，而(DV)代表从位置3处具有涂层的双层玻璃单元外侧测得的双层玻璃单元的性质，该双层玻璃单元包括具有4mm透明玻璃的钢化，涂覆玻璃板。
这证实了这些性质相对于玻璃厚度和存贮条件的稳定性。
实施例2
图2显示了双重Ag层，可热处理，通过磁控溅射沉积在玻璃基底上的涂层，并且该涂层具有如下的顺序结构：
其中ZnAlOx是包含Zn和Al的混合氧化物，在这个实施例中在氧气存在的情况下通过反应溅射靶材沉积，该靶材是Zn和Al的合金或混合物。ZnAl阻挡层是以相似的方法在基本惰性，不含氧气的气氛中通过溅射靶材沉积的，该靶材是Zn和Al的合金或混合物。
在沉积其上面的氧化物层期间，至少部分上部阻挡层15，18被氧化。然而，这些阻挡层的一部分优选保持金属形式，或者至少是未完全氧化的氧化物形式以便提供随后玻璃板热处理的阻挡层。
热处理加工之前和之后玻璃板的性质：
| 性质 | 热处理之前<sup>参见下注1</sup> | 热处理之后<sup>参见下注2</sup> |
| TL(透明度A) | 55％ | 76％ |
| TE(System Moon 2) | 43％ | |
| 雾度 | 0.07 | 0.35(包括pvb雾度) |
| a<sup>*</sup> | -9(玻璃侧) | -7(玻璃侧) |
| b<sup>*</sup> | +4(玻璃侧) | -6(玻璃侧) |
| RE(System Moon 2) | 34％(玻璃侧) |
注1：对具有涂层的单层玻璃板在热处理之前进行测量
注2：在650℃(炉温)下钢化热处理10分钟并与0.76mm的pvb和2mm的透明玻璃片层压后进行测量。
热处理优选引起氮化钛顶涂层基本完全的氧化。
热处理之前，实施例2的涂层叠层在Cleveland和ClimaticChamber试验中也表现良好。
在不背离本发明的情况下，如果需要可以在薄膜叠层排列的上部，下部或中间引入其它的层。
