Description
本发明涉及低辐射绝缘装配玻璃,其装备有包括薄“功能”层(目前为基于氮化钛)的堆叠,也就是说,基本上通过反射和/或吸收近红外(太阳)或远红外(热)辐射而作用于太阳辐射和/或热辐射。本发明更具体针对的应用是首先车辆装配玻璃,例如侧窗、天窗或后窗。在不背离本发明上下文的情况下,本装配玻璃还可以用于建筑工业领域,作为阳光控制装配玻璃。
“功能”或“活性”层在本专利申请的含义内应理解为表示堆叠的层,所述层赋予堆叠其大部分的热绝缘性质。通常,装配在装配玻璃上的由薄层制成的堆叠非常基本地通过所述活性层的固有性质赋予所述装配玻璃显著改善的绝缘性质。与其它层相比,所述层作用于穿过所述装配玻璃的热红外辐射流,所述其它层通常由介电材料制成,并且通常主要具有所述功能层的化学或机械保护功能。介电材料被理解为是指以下材料,其无大量杂质的形式表现出高电阻率,例如25℃下大于1010欧姆·米(Ω·m)的电阻率。
这种装备有薄层的堆叠的装配玻璃基本上通过由一个或多个功能层吸收入射辐射或基本上通过由这些相同的层反射而作用于入射的太阳辐射。
它们在阳光控制装配玻璃的名称下被集中在一起。它们是可商购的并且基本上用于:
-为客厢(机动车辆)或住宅提供基本保护以免受太阳辐射并防止其过热,这种装配玻璃在工业中被描述为遮阳装配玻璃(solar protection glazing),
-或基本提供住宅的热绝缘并防止热损失,这些玻璃被描述为绝缘玻璃。
热绝缘装配玻璃应理解为表示一种装配玻璃,该装配玻璃配备有赋予其减少的能量损失的至少一个功能层,所述层表现出5至50微米的反射IR辐射的性质。用于该功能的功能层表现出高IR辐射反射系数,并且被称为低辐射(或低-e)。在应用中,例如在机动车辆工业中,经常希望限制进入车辆的客厢的热量,也就是说限制太阳辐射通过装配玻璃的能量传输。在本领域中用于评价这种能力的常规参数是装配玻璃的法向辐射率,如在标准ISO 10292 (1994),Annex A中计算的。
通常,本说明书中所给出的所有光和热特性是根据国际标准ISO 9050 (2003)和ISO 10292 (1994)中所述的原理和方法获得的,分别涉及建筑工业用玻璃中所用装配玻璃的光和能量特性的测定。
目前特别探寻另外提供改善的视觉舒适性的装配玻璃,特别是在机动车辆领域(作为侧窗、后窗或也作为天窗)。为了满足这种需求,本发明的目的之一是提供合适的装配玻璃,其允许车辆的乘客或建筑物的居住者在日间光下不可或几乎不可从外部被看到,但能够在他们所位于的侧看到外部环境而没有任何麻烦。这种装配玻璃从外部起包括第一玻璃基材,优选以其本体着色(tinted in its bulk),通过中间热塑性片材粘结到第二基材上,所述中间热塑性片材特别由PVB制成,其也可以着色,所述第二基材优选由透明玻璃制成,并且装备有所述层的堆叠,所述层的堆叠优选位于其朝向车厢内部暴露的面上。根据这一要求,目前市场需要由涂有本层的堆叠的透明玻璃制成的构造制品的光透射率包括20至40%,以得到光透射率低于10%的最终层合装配玻璃。此外,还需要由涂有本层的堆叠的透明玻璃制成的构造制品的低光反射率,特别是在沉积所述堆叠的制品侧上测量时,低于10%,优选约或低于5%。
装配玻璃的另一个基本特性是其承受热处理,并且更特别是弯曲的能力,更特别是在车辆装配玻璃领域中。
这种能力通常首先通过在这种处理之后出现(更确切地说不存在)物理损坏来测量,所述物理损坏例如出现在涂层中并且对于车辆乘客高度可见的裂纹。
另一个标准也是已经经历所述热处理的装配玻璃保持(或甚至改进)其绝热性质的能力,如通过上述法向辐射率所测量的。
目前出售的解决前述复杂问题的最有效的堆叠通常通过磁控溅射技术沉积,并结合银型金属层,该银型金属层基本上以反射大部分入射IR (红外)辐射的模式操作。因此,这些堆叠主要用作低辐射(或低-e)类型的装配玻璃,用于建筑物以及车辆的热绝缘。然而,这些层对湿气非常敏感,其说明它们几乎不可以用于单个装配玻璃上,并且因此主要用于双层装配玻璃或层合装配玻璃在其面2或3上,以便防止湿气。根据本发明的堆叠不包括这种银型的层,或者实际上不包括金或铂型的层或实际上不包括铜型的层。更一般而言,根据本发明的堆叠不含有这种贵金属,或者以非常可忽略量含有,特别是以不可避免的杂质形式。
已经提出了基于堆叠的其它绝缘装配玻璃,其中氮化钛或氮氧化钛作为一个或多个功能层,使用氮化硅作为在所述功能层之上和之间的上述介电层,例如在公开WO2019/002737或US10294147B2中。然而,如下文报道的,由申请人进行的实验显示,当这种装配玻璃的涂层在其经历如弯曲的热处理(如目前在本申请的技术领域中操作的)时,其表现出裂纹。
于是,鉴于某些特定的应用或安排,使得开发新颖的且适合的堆叠成为必要。
根据申请人公司获得的结果,上述问题已经通过现在描述的玻璃制品和装配玻璃解决。
根据第一方面,本发明涉及具有阳光控制性质的玻璃制品,更特别地可用于制造车辆装配玻璃例如汽车车顶或用于制造建筑物的建筑装配玻璃,其包括至少一个装备有层的堆叠的玻璃基材,其中所述堆叠从所述基材的表面依次包括:

更特别地,本发明涉及一种玻璃制品,特别是具有阳光控制性质的车辆或建筑物装配玻璃,其包括至少一个装备有层的堆叠的玻璃基材,其中所述堆叠从所述基材的表面依次包括:

其中第三模块M3包括包含氧化硅或氮氧化硅的层,其厚度大于10 nm,优选大于20nm,和
其中,钛、铝、硅、这些元素中至少两种的合金、或镍铬合金的中间层IL沉积在所述第二层TiN2和所述第三模块M3之间,所述中间层IL的厚度为0.5 nm至7 nm,优选1 nm至6nm。

根据本发明的氮化钛不必是化学计量的(Ti/N原子比为1),而可以是过化学计量或亚化学计量的。根据一个有利的实施方案,N/Ti比为1至1.2。此外,根据本发明的氮化钛可以包含少量的氧,例如1摩尔%至10摩尔%的氧,特别是1摩尔%至5摩尔%的氧。
根据特别优选的形式,根据本发明的氮化钛层对应于通式TiNxOy,其中1.00<x<1.20且其中0.01<y<0.10。

根据本发明的装配玻璃可以是包含(可能以其本体着色,tinted in its mass)单一玻璃基材的单一装配玻璃,其中薄层的堆叠位于单一装配玻璃的面2上,基材的面从其所装备的建筑物或客厢的外部向内部编号。

上述玻璃制品可以非常明显地被回火和/或弯曲。
根据本发明的制品/装配玻璃的制造方法包括例如至少以下阶段:
-将玻璃基材引入阴极溅射装置中,
-在第一隔室中,沉积至少一个介电材料的底层,
-在随后的隔室中,通过由含氮气体产生的等离子体溅射钛靶,
-在随后的隔室中,沉积介电材料的至少一个中间层,
-在随后的隔室中,通过由含氮气体产生的等离子体溅射钛靶,
-在随后的隔室中,沉积介电材料的至少一个覆盖层。
此外,当在堆叠内适当时,在中间隔室中,通过由氩气产生的等离子体溅射由钛、铝、硅、这些元素中的至少两种的合金或镍铬合金制成的金属靶,用于沉积上述IL中间层。
在本说明书中,术语“底层”和“覆盖层”是指所述层相对于堆叠中的一个或多个功能层的相应位置,所述堆叠由玻璃基材支撑。特别地,当堆叠含有单个底层和单个覆盖层时,底层是与玻璃基材接触的层,并且覆盖层是堆叠的最外层,背向基材。
术语“中间层”表示位于分别设置在其下和其上的两个相关层之间的一个或多个层,该相关层之一通常为包含氮化钛的层。
在本发明的含义内,层的厚度应理解为意指层的真实几何厚度,如可以具体地通过常规电子显微镜技术或类似技术测量的。
根据本发明的涂层通常通过待沉积材料或材料前体的阴极的磁场辅助真空溅射类型的沉积技术来沉积,所述沉积技术在本领域中通常称为磁控溅射技术。这种技术目前被广泛使用并且是公知的,特别是当待沉积的涂层由厚度为几纳米或几十纳米的连续层的更复杂的堆叠组成时。根据本发明的一个或多个金属中间层(IL)通过在惰性气体(通常为氩气)的中性气氛中溅射由相应金属制成的靶而沉积。例如,通过在100%氩气氛中溅射钛靶来沉积Ti制成的中间层。然而,主张可能在热处理过程中,例如在最终装配玻璃的弯曲或回火中,该中间层的一部分可以部分氧化或氮化。
下面通过非限制性实施例更详细地描述本发明及其优点,所述实施例是根据本发明的和对比的。在所有的实施例和说明书中,除非另有说明,给出的厚度是几何厚度。
实施例的所有基材由Saint-Gobain Glass France出售的Planiclear型厚度为2mm的透明玻璃制成。所有层都以已知的方式通过磁场辅助阴极溅射来沉积,通常称为如上所述的磁控阴极溅射。
以公知的方式,在阴极溅射装置的连续隔室中沉积不同的连续层,每个隔室在适当气氛中装备有由Si (掺杂有铝)或Ti制成的特定金属靶,如选择用于沉积堆叠的特定层。
更具体地说,在含有与氩气混合的氮气的反应性气氛中,由金属硅靶(掺杂有8重量%的铝)在设备的隔室中沉积氮化硅层。因此,氮化硅层也含有铝。
更具体地说,在含有与氩气混合的氧气的反应性气氛中,由相同的金属硅靶(掺杂有8重量%的铝)在设备的隔室中沉积氧化硅层。因此,氧化硅层也含有铝。
因此,本领域技术人员将理解,在本发明的含义内,这些层被认为是基于氮化硅或氧化硅的。
在仅含有氮气和氩气的反应性气氛中,由纯金属钛靶在设备的其它隔室中沉积氮化钛层。
在仅含有氩气的气氛中,从相同的纯金属钛靶在装置的隔室中沉积钛中间层。
用于磁控沉积这些层的条件在技术上是本领域公知的。
在随后的实施例中,玻璃基材因此连续地被包括两个由氮化钛(为了方便,随后表示为TiN,即使层的实际化学计量并非必须如此)制成的功能层的层的堆叠覆盖。对于所有的实施例,置于玻璃表面和第一功能层TiN1之间的第一模块M1由氮化硅(为了方便,随后表示为Si3N4,即使层的实际化学计量并非必须如此)制成。使用氮化硅或氧化硅(为了方便,随后表示为SiO2,即使层的实际化学计量并非必须如此)对第二模块M2和第三模块M3的不同构造进行实验,以检查所得到的堆叠在提供热绝缘性质的同时经受住诸如弯曲工艺的加热方法的能力,随着所使用材料的变化而变化。
根据用于磁控沉积的常规技术调节沉积条件,以便获得不同的堆叠,其层序列及其厚度(以纳米nm计)在下表1中给出,从玻璃表面开始:

A-装配玻璃特性的测量
根据以下原理和标准测量由此获得的玻璃制品的热和光学特性:
1°)光学性质:
根据欧洲标准ISO 9050 (2003)进行测量。更具体而言,根据光源D65,在380和780nm之间测量堆叠RLc侧上的光透射率TL和光反射率。
2°)热性质:
B-结果
将根据上述实施例的单片玻璃制品获得的结果一起集中至表2,其如下:
观察到根据本发明获得的这种玻璃制品表现出低的光反射率(小于10%),然而光透射率没有过分高(约20-25%)。这种特性使得这种玻璃制品能够作为装配玻璃的一部分插入,所述装配玻璃例如市场所需的天窗,其适于令车辆乘客或装备有这种装配玻璃的建筑物的居住者可以无阻挡地观察车辆外部的用途。
根据比较例1 (根据前面引用的现有技术)的制品不能经受所施加的热处理,如观察到的非常大量的裂纹所示。然而,其能量绝缘性能是可接受的,如由低辐射率值表示的。根据比较例2和3的装配玻璃,其中若干一个或多个氮化硅层已经被一个或多个其它的氧化硅代替,具有更好的耐热处理性,但是热绝缘性质降低。
通过比较,根据本发明的实施例4至6在耐热处理性和热绝缘性能之间呈现最佳折衷。特别地,实施例5和6表现出与现有技术中的堆叠所获得的辐射率值(参见实施例1)相当的辐射率值,但在弯曲加工后没有裂纹。
