本申请要求2002年5月31日申请的美国临时申请序列号60/384857的权益,其全部内容都引入本文,供作参考。
                      发明背景
1.发明领域
本发明总体上涉及制造涂敷制品的方法,例如(但不限于)桌面、浴室门、隔板、和汽车透明体,还涉及由此制成的制品。
2.技术现状
在今天的汽车市场上,主要重点放在车辆式样中。对于车辆销售来说,车辆外观与车辆的机械可靠性或安全特性同样重要。因此,汽车制造商尽一切所能来提高车辆式样。这些式样改进包括向顾客提供更多的颜色选择和提供具有金属薄片的颜色以使车辆具有“多色效果”。
尽管这些式样改进通常都已经被消费者充分接受,但是,到目前为止,仍然存在着这样一个问题,即使有新的车辆油漆罩面层,汽车透明体(例如(但不限于)挡风玻璃、侧窗、后窗、月光篷顶和遮阳篷顶)依旧通常是灰色或中性颜色的。除了提供防阳光性能,这些常规透明体对于车辆式样没有改进。
在非汽车领域,业已知道提供其中颜色由基材和涂层之间的干涉效应产生的涂敷制品。如本领域技术人员所知道的,术语“干涉效应”是指电磁波振幅随着距离或时间的变化,它是由电磁辐射(例如可见光)波的叠加而引起的。这些电磁波可以是在光学薄膜涂层中的一个或多个层的界面处的反射或透射的结果。例如,US6164777公开了具有由交替的不同折射率材料制成的干涉涂层的塑料接触镜。US5923471公开了用于加热灯的具有交替的氧化锆和氧化硅层的“热镜”。美国专利公开文本US2003/0031842A1公开了一种具有图案外观(由一个或多个普通透明薄膜涂层之间的肉眼可观察到的反差提供)的制品。干涉涂层和涂敷制品的其它实例公开在美国专利US5619059、US4902581、US5112693、和瑞士专利339575之中。
尽管这些公开的涂层适合于它们的预期目的,但是在试图将干涉涂层结合到汽车透明体之中时仍需要考虑许多其它问题。例如,在美国,政府法规要求所有挡风玻璃都必须具有至少70%的光线的(可见的)透光率(Lta)。在欧洲,要求的最小Lta是75%。由于干涉涂层的存在,将会对透明体的透光率产生不利的影响。
提供一种制造美学上是令人愉快的且能用来改进汽车式样的汽车透明体的方法将是受人欢迎的。提供一种能够使透明体的颜色与汽车油漆颜色相符或相匹配成为可能的汽车透明体也将是受人欢迎的。如果这类透明体还能符合对于汽车透明体政府要求的规格,则将是更加受人欢迎的。
                         发明概述
本发明的制品如汽车透明体,包括第一基材和至少一种沉积在所述基材至少一部分之上的美观涂层。所述至少一种美观涂层可为所述制品提供由-10≤a*≤0和/或-15≤b*≤5所限定的颜色和/或在8-50%范围的可见光反射率。例如,制品可具有的a*值在-5至0范围之内,如-4至-1,如-4至-1.5。制品可具有的b*值在-10至+4范围之内,如-8至+3。制品可具有的反射率在8-25%范围之内,如8-20%,如16-20%,如9-18%。本发明制品可为层压制品或整体制品。在一种特定实施方式中,对于汽车透明体来说,所述可见光反射率可在8-30%范围之内。
在一种非限制性实施方式中,所述制品具有银色外观,且所述美观涂层提供的a*值是在-4至0范围之内,其b*值是在-10至-6范围之内。在另一种非限制性实施方式中,所述制品具有白镴(pewter)外观,且所述美观涂层提供的a*值是在-5至-1范围之内,其b*值是在-3至+3范围之内。
一种制造制品如具有至少一种美观涂层的汽车透明体的方法,包括沉积至少一种美观涂层在第一基材的至少一部分上的步骤。所述至少一种美观涂层沉积的厚度足以为第一基材提供由-5≤a*≤0和/或-15≤b*≤5所限定的颜色和/或在8-50%例如8-30%范围的可见光反射率。

由下述讨论将会理解,本发明所述美观涂层可用于制造层压或非层压的制品中,例如单层制品。将首先对本发明示例性整体制品进行说明,接着,将对本发明的示例性层压制品进行说明。至于“整体”是表示具有单一结构基材或主要层(ply),例如玻璃层。所述示例性制品(无论层压制品或整体制品)是以汽车侧窗进行说明的。但是,本发明不局限于汽车侧窗,它可用于任意制品,例如(但不限于)绝缘玻璃元件、住宅或商用层压窗(如天窗)、浴室门、隔板、桌面、或用于陆地、空中、空间、水上和水下运载工具的透明体如汽车挡风玻璃、后窗、遮阳篷顶、月光篷顶等。
图1图示说明了结合本发明特征的示例性涂敷制品10。所述制品10包括一个基材12,它具有第一主表面14和第二主表面16。本发明至少一种美观涂层20提供在至少一个所述主表面14、16的至少一部分之上。在图1所示的示例性实施方式中,所述至少一种美观涂层20,提供在全部或基本全部的第一表面14之上。至于“沉积在基本全部的第一表面之上”表示所述至少一种美观涂层20覆盖了所述表面的大部分,而不是在离散的区域中形成。在一种实施方式中,所述至少一种美观涂层20可被提供在除了邻近或沿着第一表面14的周边边缘的非涂敷区域之外的全部第一表面14之上。在另一种实施方式中,当美观涂层妨碍所需的电磁辐射透过率时,一个或多个更小区域的所述涂层可被消去或被除去(或在涂敷之前被掩蔽),如对于天线和“Easy-Pass”涂敷。如下将作更详细的描述,任选的功能性涂层22,可沉积在一个或多个所述主表面14、16的至少一部分之上,例如,在所述至少一种美观涂层20和所述基材12之间,或者沉积在所述美观涂层20之上,或者,所述美观涂层20可结合到所述功能性涂层的涂层叠层之中。如下所述,任选的保护涂层24可提供在所述至少一种美观涂层20的至少一部分之上。任选的涂层30如陶瓷涂层或遮光条带,也可沉积在第二主表面16的至少一部分之上。
在本发明的广泛应用中,所述基材12不限于本发明,可为任意具有任何所需特征的材料,如对于可见光不透明、半透明或透明的材料。至于“透明”是表示具有大于0-100%的通过所述基材的透光率。或者,所述基材可以是半透明或不透明的。至于“半透明”是表示能够允许电磁能(如可见光)透过所述基材,但散射这种能量,使得在基材与观察者相对一侧的物体不能清楚地可见。至于“不透明”是表示具有0%的可见光透光率。合适的基材实例包括(但不限于)塑料基材(如丙烯酸类聚合物,如聚丙烯酸酯;聚烷基甲基丙烯酸酯,如聚甲基丙烯酸甲酯、聚甲基丙烯酸乙酯、聚甲基丙烯酸丙酯等;聚氨酯;聚碳酸酯;聚烷基对苯二甲酸酯,如聚对苯二甲酸乙二醇酯(PET)、聚对苯二甲酸丙二醇酯、聚对苯二甲酸丁二醇酯等;含聚硅氧烷聚合物;或任意用于制备这些聚合物的单体或其任意混合物的共聚物);金属基材,例如(但不限于)镀锌钢、不锈钢、和铝;陶瓷基材;砖基材;玻璃基材;或任意上述物质的混合物或组合。例如,所述基材可为常规的无色钠钙玻璃,即“透明玻璃”,或者可为带色彩的或着色玻璃、硼硅酸盐玻璃、含铅玻璃、回火的、非回火的、退火的、或热强化玻璃。所述玻璃可为任意类型,如常规的浮法玻璃或平板玻璃,且可为任意具有任意光学性能的组成,例如,任意数值的可见光辐射透射、紫外线辐射透射、红外线辐射透射、和/或总的阳光能量透射。典型汽车类玻璃可具有如蓝色、绿色、青铜色、灰色,这些玻璃的非排他性实例包括可自PPG Industries,Inc.of Pittsburgh,Pennsylvania购买得到的玻璃,商品名称为Solex玻璃、Solargreen玻璃、Solextra玻璃、和VistaGrayTM玻璃。这些玻璃可为未回火的、热处理的、或热强化玻璃。本文所述术语“热处理的”表示加热到足以弯曲或退火或回火所述玻璃的温度。所述术语“热强化的”表示退火的、回火的、或至少部分回火的。虽然不限制于本发明,适合于所述基材12的实例,公开在US4746347、US4792536、US5240886、US5385872、和US5393593之中。所述基材12可为任意所需的尺寸,例如长度、宽度、形状、或厚度。对于常规汽车透明体来说,所述基材12典型地可达10mm厚,如1-10mm厚,如低于10mm厚,如1-5mm厚,如1.5-2.5mm,如1.6-2.3mm。所述基材12可为平板基材,或者可为成形的、弯曲的、或曲面的。至于术语“平板基材”是表示基本以单一几何平面放置的基材,例如,由常规浮法玻璃方法制得的玻璃。而“成形的”或“弯曲的”是表示不是平板的基材。
所述至少一种美观涂层20,可为干涉涂层,用来为所述涂敷制品10提供美观特征,但它不会或仅会轻微地影响所述涂敷制品10的防阳光性能。本文所用术语“干涉涂层”是指由于干涉效应(如前所述)能够产生颜色(例如在透射或反射中)的涂层。在一种实施方式中,所述美观涂层20包括一层或多层的涂层材料,具有足以能够为所述涂敷制品10提供可见光反射率在8-50%范围的厚度,例如反射率为8-30%,例如8-25%,例如8-20%,例如16-20%,例如9-18%。所述美观涂层20可提供在由-10≤a*≤0限定的色空间之内的反射颜色,例如在-8至0范围之内,例如在-6至0,例如-5至0,例如-4至-1,例如-4至-1.5。所述美观涂层20可提供范围在-15≤b*≤5的b*值,例如-10至+4,例如-8至+3。
如本领域技术人员所知,物体(特别是玻璃)的颜色,是高度主观性的。观察到的颜色将依赖于照明条件和观察者的喜好。为了在定量的基准上评价,业已经开发了多种色级体系。一种被国际照明协会(CIE)采用的确定颜色的方法,是使用主波长(DW)和色纯度(Pe)。对于一种给定颜色的这两种技术标准的数值,可通过计算来自所谓颜色的三色值X、Y、Z的颜色坐标x和y而确定。所述颜色坐标标绘在1931 CIE色度图上,并与CIE标准光源C的坐标进行数量对比,后者标记在CIE出版号No.15.2中。这种比较可在所述色度图上提供色空间,以确定所述玻璃颜色的色纯度和主波长。
在另一种色级体系中,颜色是以色调和明度来进行规定的。这种体系通常称作CIELAB颜色体系。色调区分颜色如红色、黄色、绿和蓝色等颜色。明度或数值区分明或暗的程度。这些特征的数值(它们标记为L*、a*和b*),是由三色值(X、Y、Z)计算得到的。L*指示颜色的明度或暗度,并表示该颜色处于的明度平面。a*指示在红(+a*)绿(-a*)坐标轴上该颜色的位置。b*指示在黄(+b*)蓝(-b*)坐标轴上该颜色的位置。当所述CIELAB体系的直角坐标转换为柱面极坐标时,所得到的颜色体系被称作CIELCH颜色体系,它以明度(L*)、和色调角(H°)和色度(C*)来确定颜色。L*指示在所述CIELAB体系中颜色的明度或暗度。色度(或饱和度或强度)区分颜色的强度或清晰度(即明亮相对于晦暗),它是从该色空间中心到所测量的矢量距离。颜色的色度越低,即其强度越小,则该颜色越接近于所谓的中性颜色。对于所述CIELAB体系来说,C*=(a*2+b*2)1/2。色调角区分颜色如红色、黄色、绿和蓝色,它是从所述红(+a*)轴逆时针方向测得的经过所述CIELCH色空间中心的自所述a*、b*坐标延伸矢量的角度数值。
能够理解,颜色可以以任意的这些颜色体系进行表征,本领域技术人员可以从观察玻璃或复合透明体的透光率曲线计算出等价的DW和Pe数值;L*、a*、b*数值;和L*、C*、H°数值。颜色计算的详细讨论公开在US5792559中。在该文献中,颜色是通过使用所述CIELAB体系(L*a*b*)计算得到。但是,也应该明白,这仅是为了讨论的方便,所公开的颜色可由任意常规体系来确定,如上述的那些体系。
在一种实施方式中,所述美观涂层20包括一层或多层金属氧化物涂层材料,所具有的厚度足以产生由-10≤a*≤0和-15≤b*≤5限定的干涉效应颜色且反射率在8-50%范围内如8-30%。可用于本发明的示例性材料包括(但不限于)氧化硅、氧化铝、氧化锌、氧化锡、氧化铌、氧化钽、氧化锆、氧化钛、碳(本领域人员常称作“类金刚石碳”或DLC)、氧化铝、锌和锡材料(例如(但不限于)锡酸锌)和金属的氧化物、氮化物、或氮氧化物如氮氧化硅、或含有任意一种或多种上述材料的任意混合物。
所述至少一种美观涂层20还包括一种或多种添加剂或掺杂剂,以影响所述至少一种美观涂层20的性能,如折射率、光催化活性、和本领域技术人员已知的其它性质。掺杂剂的实例包括(但不限于)钠、镍、过渡金属、和含有任意一种或多种前述物质的混合物。
所述至少一种美观涂层20可为任意厚度,以获得如上所述所需的颜色和反射率。本领域技术人员将会理解,所述至少一种美观涂层20的具体厚度可根据选用的材料而变化,以获得所述所需的颜色和反射率。所述至少一种美观涂层20具有的最小厚度大于0。在一种非限制性实施方式中,所述至少一种美观涂层20的最大厚度为20000,例如15000,例如10000。对于大于约1.5微米的光学厚度来说,所述至少一种美观涂层20可表现出厚膜性态(例如,其定义见“Optics ofThin Films”,A.Vasicek,North Holland Publishing Company,Amsterdam,Interscience Publishers Inc.New York,NY,1960,pg.139)。例如,折射率约1.5的氧化硅,可在物理厚度约9167(或约1微米)时表现出厚膜性态,折射率约2.5的氧化钛在约5500(约0.5微米)时表现出厚膜性态。在一种非限制性实施方式中,所述美观涂层20可具有的厚度在大于0-20000 范围内,例如大于0-10000,大于0-5000,例如大于0-1000,例如100-500。另外,所述至少一种美观涂层20,当它进行沉积时,在整个表面上没有必要是均匀厚度。例如,所述至少一种美观涂层20可以是非均匀的或变动的厚度(例如,具有较高或较低的厚度区域),以便在所述涂敷表面上提供能够感觉到的色差,例如彩虹效果。
除了上述的a*、b*尺寸之外,所述涂敷制品10还具有足以能够为所述涂敷制品10提供所需水平的明度以获得美学上令人愉快外观的L*值。在一种非限制性实施方式中,所述涂敷制品10具有的L*值在45-55范围之内。
对用于向前的汽车透明体(例如挡风玻璃和前侧窗)来说,所述涂敷制品10可具有的Lta值大于或等于70%,例如大于或等于75%。对于非向前的视觉面板(例如“隐避玻璃”)来说,所述Lta值可小于75%,例如小于70%。
为了为所述涂敷制品10(特别是层压汽车透明体)提供美学上受人欢迎的光泽或光彩,所述涂敷(层压)制品10可具有范围在8-50%的可见光反射率,例如8-30%,例如8-25%,例如8-20%,例如15-25%,例如16-20%,例如9-19%。本领域技术人员将会理解,对于层压制品来说,所述反射率通常采用所述层压制品的外部反射率来限定。所述“外部反射率”表示具有美观涂层提供在一个内部表面如2号表面或3号表面上的该外部表面(1号表面)的反射率。
所述至少一种美观涂层20可为具有两层或多层的具有不同折射率的涂层材料的多层涂层叠层。例如,所述至少一种美观涂层20可包括至少一种具有第一(低的)折射率的第一层和至少一种提供在第一层之上的具有第二(高的)折射率的其它层。一种替代方案是,所述至少一种美观涂层可具有第一(低的)折射率层、第二(高的)折射率层、和第三(中等)折射率层,第一、第二和第三层可以任意所需的顺序进行沉积。例如,第二(高的)折射率层可提供在第一(低的)折射率层之上,而第三(中等)折射率层沉积在第二(高的)折射率层之上。一种替代方案是,所述美观涂层可包括第一(中等)折射率层、提供在第一层之上的第二(低的)折射率层、和提供在第二层之上的第三(高的)折射率层。
术语“低的”、“中等”、和“高的”可以是针对所述涂层叠层材料的相对术语。例如,在涂层叠层中,“中等”折射率材料可为任意的具有折射率大于所述“低的”折射率材料(即所述叠层材料中具有最低相对折射率数值的材料)折射率的材料,“高的”折射率材料可为任意的具有折射率大于所述中等折射率材料折射率的材料。在一种实施方式中,所述材料可以是在最接近所述基材(例如玻璃)上沉积“中等”折射率材料,所述“低的”折射率材料沉积在所述中等折射率材料之上,所述“高的”折射率材料沉积在所述低的折射率材料之上。一种用来说明这种结构的示例性涂层叠层是:氧化铝层沉积在基材上,氧化硅层沉积在所述氧化铝层上,氧化钛层沉积在所述氧化硅层上。在一种特定实施方式中,所述“低的折射率”材料可具有低于1.7的折射率。所述“高的折射率”材料可具有大于2.1的折射率。所述“中等折射率”材料可具有范围在1.7-2.1之间的折射率。在这种实施方式中,氧化硅和氧化铝是低的折射率材料的实例。氧化钛将是高的折射率材料的实例。锡酸锌和氧化锆是中等折射率材料的实例。在一种示例性的两层体系中,第一涂层层可含有锡酸锌,第二涂层层可含有氧化钛。在一种实施方式中,所述锡酸锌层可具有的厚度在100-300范围之内,例如200,所述氧化钛层具有的厚度在100-300范围之内,例如200。
所述至少一种美观涂层20可包括单一层,例如(但不限于)氧化锆。在一种实施方式中,所述单一氧化锆层可具有的厚度是在70-700范围之内。在另一种实施方式中,所述美观涂层20可包括一种或多种分级(graded)的层。“分级的”是表示这样一种涂层,在从所述层的一个表面或界面向相对表面或界面移动时,其一种或多种成分的分数提高,而一种或多种其它成分的分数降低。例如,在一种实施方式中,所述美观涂层20可包括分级的氧化硅-氧化锆层(即这样的层,其组成从一个表面上的0wt%氧化锆和100wt%氧化硅变化到相对表面上的100wt%氧化锆和0wt%氧化硅),任选的氧化锆层沉积在所述分级层之上。在另一种实施方式中,所述分级的层可具有的厚度为2000,所述任选氧化锆层可具有的厚度为10000。在另一方面所述分级的层可从一种类型材料如氧化物变化为另一种类型材料如氮化物。例如,所述分级层可从氧化硅变化为氮化硅。
所述至少一种美观涂层20可以任意常规方法进行沉积,例如(但不限于)磁控管溅射汽相沉积(MSVD)、热解沉积如化学汽相沉积(CVD)、喷雾热解、大气压力CVD(APCVD)、低压CVD(LPCVD)、等离子体增强CVD(PEVCD)、等离子体辅助CVD(PACVD)、或电阻或电子束加热的热蒸发、阴极电弧沉积、等离子体喷雾沉积、湿法化学沉积(例如溶胶-凝胶、镜面镀银等)、或任意其它理想的方法。在一种实施方式中,所述至少一种美观涂层20可通过MSVD法进行沉积。MSVD涂敷装置和方法的实例,对于本领域技术人员来说是已知的,例如,公开在US4379040、US4861669、US4898789、US4898790、US4900633、US4920006、US4938857、US5328768、和US5492750之中。在所述MSVD法中,金属或金属合金的氧化物可通过在含氧气氛中溅射含金属或金属合金的阴极以沉积金属氧化物或金属合金氧化物膜到所述基材表面上而实现沉积。在一种实施方式中,所述美观涂层20沉积在全部或基本全部所述表面14上,即不沉积形成离散的涂敷区域。所述至少一种美观涂层20可沉积在平板基材之上,接着所述基材以任意常规方法进行弯曲或成形。一种替代方案是,所述至少一种美观涂层20可沉积在弯曲表面上,例如,业已被弯曲或成形的基材上。
在如图1所示的整体实施方式中,任选功能性涂层22可沉积在一个或多个所述表面14、16之上,如位于所述基材12和所述至少一种美观涂层20之间,沉积在所述美观涂层20之上,或者所述美观涂层20可结合到所述性涂层22的涂层叠层之中。所述功能性涂层22可为任意所需的类型。本文所用的术语“功能性涂层”是指这样一种涂层,它能够改进其沉积于其上的所述基材的一种或多种物理性质,例如,光学、热学、化学、机械性能,而且在随后加工过程中它不易于完全地从所述基材上除去。所述功能性涂层22可以具有一种或多种由相同或不同组成或功能的功能性涂层薄膜或层。
