然而, 对玻璃材质采用上述工艺处理时, 由于上述处理工艺同质化严重, 这样造成玻璃 材质产品的外观没有新的突破, 比较单一, 即玻璃材质应用到手机等终端产品上时, 终端产 品的外观质量没有得到提升, 从而造成产品的外观缺乏竞争力。

其中,本实施例中,镀膜层 20的反射光谱曲线具体为不同波长与反射率构成的光谱曲线, 其中, 反射光谱曲线中横坐标为波长, 纵坐标为反射率, 反射率斜率为反射光谱曲线中两个 位置之间的连线对应的倾斜程度, 所以, 本实施例中, 镀膜层 20的反射光谱曲线中具有两个 以上反射率斜率大于阈值的区域,即表明镀膜层 20的反射光谱曲线中有两个以上的区域的反 射率斜率大于阈值,这样使得镀膜层 20的反射光谱曲线中具有两个以上的反射率斜率较大的 区域, 其中, 本实施例中, 阈值具体为倾斜角度为 30° 时对应的斜率值。
其中, 本实施例中, 镀膜层 20的反射光谱曲线中可以具有三个反射率斜率较大(即大于 阈值)的区域, 或者镀膜层 20的反射光谱曲线中可以具有四个反射率斜率较大的区域, 在实 际应用中,为了实现变色,镀膜层 20的反射光谱曲线中往往具有三个反射率斜率较大的区域, 这样使得镀膜层 20在反射过程中会出现两种不同的颜色。
其中, 本实施例中, 镀膜层 20包括三层结构时, 分别为第一层、 第二层和第三层, 第二 层位于第一层和第三层之间, 此时, 第二层厚度大于其他两层的厚度, 其中, 镀膜层 20还可 以包括 5层结构, 分别为第一层、 第二层、 第三层、 第四层、 第五层, 其中, 中间层为第二 层、 第三层、 第四层, 这样, 第二层、 第三层、 第四层中的任一一层厚度大于第一层、 第二 层、 第三层、 第四层、 第五层中的其他任一一层厚度, 例如, 第二层厚度大于第一层厚度, 或者, 第二层大于第三层厚度。
其中, 本实施例中, 需要说明的是, 镀膜层 20包括的至少三层结构均为功能层, 即本实 施例中, 镀膜层 20的功能层层数为至少三层, 其中, 功能层具体为镀膜层 20中的有效层, 在实际应用中,镀膜层 20的功能层外设可以有两层连接层(即功能层位于两个连接层之间), 连接层为无效层, 连接层为了保证镀层和油墨 (衬底往往为油墨层) 附着力, 连接层的镀膜 材料往往为氧化硅, 其中, 功能层的镀膜材料具体为氧化硅、 氧化铌、 金属铟、 氧化钦等。
本申请提供的功能膜片 100, 通过将至少三层结构的中间任一一层厚度大于至少三层结 构的其他任 -层厚度, 同时, 至少三层结构中的各层厚度严重不均匀, 以使镀膜层 20的反 射光谱曲线中具有两个以上反射率斜率大于阈值的区域, 这样以不同角度观察镀膜层时, 镀 膜层的反射光谱曲线左移, 使得光谱特性发生变化, 最终使得不同角度观察镀膜层时观察到 两种不同的颜色, 功能膜片即可实现变色, 而且在角度越大时变色越明显, 即功能膜片 100 实现了大角度变色, 这样人眼对设有功能膜片 100观察时, 观察角度不同所观察的颜色也不 同, 从而使得设有功能膜片 100的产品光影和颜色效果更加丰富、 更炫亮, 大大提升了产品 的外观竞争力, 因此, 本实施例提供的功能膜片 100实现了大角度变色, 从而使得玻璃材质 产品的颜色和光影层次更加丰富, 提升了玻璃产品的外观美观性, 解决了现有玻璃材质由于 处理工艺同质化严重而造成玻璃材质产品的外观质量没有得到提升的问题。
在一种可能的实施方式中, 本实施例中, 由于至少三层结构的中间任一一层厚度大于至 少三层结构的其他任一一层厚度时,若中间的一层与其他某一层之间的厚度差较小或较大时, 镀膜层 20可以实现变色, 但是变色不是彳艮明显, 即颜色变化开始缩小, 因此, 本实施例中, 为了确保镀膜层 20变色较大, 颜色变化更明显, 具体将至少三层结构的中间任一一层厚度为 至少三层结构的其他任—层厚度的 2〜 3倍,即镀膜层 20的中间某一层为其他层中的某一层 厚度的 2〜 3倍,举例来说,镀膜层 20包括三层结构,分别为第一层、第二层和第三层,此时, 第二层厚度为其他两层的 2倍或 3倍, 在实际应用中, 当镀膜层 20包括三层结构时, 中间的 第二层为其他两层的 3倍, 本实施例中, 至少三层结构的中间任一一层厚度设置为至少三层 结构的其他任—层厚度的 2〜 3倍时,镀膜层 20在可见光谱内会产生两至三个反射率斜率较 大的区域,这样膜片变色更大,这样在不同角度观察膜片时,膜片在大角度时的变色更明显, 这样呈现出显眼的不同颜色。
其中, 本实施例中, 需要说明的是, 至少三层结构的中间任一一层厚度为至少三层结构 的其他任一一层厚度的 2〜 3倍时, 镀膜层 20的变色较大, 但是若至少三层结构的中间任一一 层厚度为至少三层结构的其他任—层厚度的 2〜 3倍左右时,例如为 1.5倍或 3.5倍时,此时, 镀膜层 20的颜色变化开始缩小, 即变色不明显。 其中, 本实施例中, 至少三层结构的中间任 —层厚度为至少三层结构的其他任—层厚度的 2.5-3倍时变色最大, 颜色变化最明显。
其中, 本实施例中, 举例来说, 若镀膜层 20包括 4层结构, 若第三层为厚度为 120nm, 则其余三层中的某一层厚度厚度为 40-60nm,例如第一层为 40-60nm,或者第二层为 40-60nm, 或者第四层厚度为 40-60nm。 这样第三层与其中一层厚度满足 2〜 3倍, 这样镀膜层 20可以实 现大角度变色。
其中, 功能膜片 100的反射光谱曲线随着角度变化(0。、 5。、 30。、 45。、 60。、 75。) 时, 反射光谱曲线左移(光谱色从长波颜色往短波颜色变化), 同时曲线形态产生变化(颜色的亮 度, 饱和度都产生变化), 在 30度以内颜色变化不明显, 45度到 75度颜色变化非常大。
本实施例提供的功能膜片 100, 通过至少三层结构的中间任—层厚度为至少三层结构 的其他任一一层厚度的 2〜 3倍时,使得镀膜层 20的反射光谱曲线中具有两个以上的反射率斜 率较大的区域, 以不同角度观察镀膜层时, 镀膜层 20的反射光谱曲线左移, 使得光谱特性发 生变化, 最终使得不同角度观察镀膜层时观察到至少两种不同的颜色, 这样人眼对设有功能 膜片 100观察时, 观察角度不同所观察的颜色也会不同, 尤其在大角度时, 功能膜片 100变 色, 即功能膜片 100实现了大角度变色的目的, 这样使得设有功能膜片 100的产品光影和颜 色效果更加丰富、 更炫亮, 大大提升了产品的外观竞争力, 因此, 本实施例提供的功能膜片 100 实现了大角度变色的目的, 这样使得玻璃材质产品的颜色和光影层次更加丰富, 从而提 升了玻璃产品的外观美观性, 解决了现有玻璃材质由于处理工艺同质化严重而造成玻璃材质 产品的外观质量没有得到提升的问题。
在一种可能的实施方式中,镀膜层 20的中间最厚一层厚度介于 100-300nm, 即镀膜层 20 的功能层中的最厚的一层大于 100nm, 且小于 300nm。
在一种可能的实施方式中,由于镀膜层 20在光滑的材料和物体表面上呈现的颜色变化谷丈 弱, 大角度变色不明显, 为了在大角度时变色比较明显, 本实施例中, 如图 3所示, 基底 10 与镀膜层 20之间具有胶层 40, 胶层 40朝向镀膜层 20的一面上具有沟槽纹理, 且镀膜层 20 的表面与沟槽纹理相匹配, 这样镀膜层 20附在纹理沟槽表面, 光线形成漫反射, 漫反射后的 颜色随着角度变化比较明显, 这样旋转产品角度有明显变色的炫光变幻效果, 因此, 本实施 例中, 在大角度变色的基础上设置沟槽纹理使得功能膜片 100的变色效果更加明显, 从而使 得应用该功能膜片 100的产品有明显变色的炫光变幻效果, 产品外观更加炫亮。
其中, 本实施例中, 沟槽纹理具体通过纹理磨具在胶层 40上进行压印形成, 其中, 由于 镀膜层 20通过光学镀膜方式形成, 所以在胶层 40上镀膜时,镀膜层 20首先填充在沟槽纹理 中, 最终形成的镀膜层 20的表面与沟槽纹理相匹配(如图 3所示), 这样在镀膜层 20上设置 衬底 30时, 衬底 30需将镀膜层 20填平, 所以如图 3所示, 衬底 30朝向镀膜层 20的一面与 沟槽纹理也是相匹配的。
其中, 本实施例中, 胶层 40具体为 UV胶层, 通过将胶层 40设置为 UV胶层, 这样 UV 胶层耐镀膜层 20应力产生的影响, 从而可以减少镀膜层 20在 UV胶层上镀膜后 UV胶层的 断裂, 进而减少了膜片表面出现不良的风险。
其中, 本实施例中, UV胶层的厚度具体可以为 13 。
其中, 本实施例中, 在胶层 40上形成沟槽纹理时, 具体的, 沟槽纹理为微纳纹理, 即沟 槽纹理为微米级或纳米级的纹理。
其中, 本实施例中, 沟槽纹理的截面呈凹凸起伏状, 如图 3所示, 沟槽纹理的截面呈波 浪状, 在实际应用中, 沟槽纹理的截面还可以为其他彳敖纳波纹。
在一种可能的实施方式中, 镀膜层 20的厚度介于 250腿-800腿, 例如, 镀膜层 20的厚 度可以为 400nm, 或者也可以为 500nm等, 具体的厚度根据实际需求进行设置。
在一种可能的实施方式中, 镀膜层 20包括 7层结构, 具体如图 2所示, 镀膜层 20的 7 层结构具体为: 第一氧化硅层 21a、 金属铟层 22a、 第二氧化硅层 23a、 第一氧化铌层 24a、 第三氧化硅层 25a、 第二氧化铌层 26a和第四氧化硅层 27a, 其中, 第一氧化娃层 21a、 金属 铟层 22a、 第一氧化铌层 24a、 第二氧化硅层 23a、 第二氧化铌层 26a、 第三氧化硅层 25a和 第四氧化硅层 27a从下到上依次叠加设置, 其中, 如图 2所示, 第一氧化硅层 21a厚度为 10-20nm、 金属铟层 22a的厚度为 21nm、 第二氧化硅层 23a厚度为 53nm、 第一氧化铌层 24a 厚度为 69nm、 第三氧化硅层 25a厚度为 81nm、 第二氧化铌层 26a厚度为 126nm和第四氧化 娃层 27a厚度为 10-20nm。此时,将包括该镀膜层 20的功能膜片 100贴合到玻璃上进行观察, 具体的:
观察角度分别为垂直产品, 即入射角 0度(如图 4a所示), 倾斜法线 15度, 即入射角 15度(如图 4b所示), 倾斜法线 30度, 即入射角 30度(如图 4c所示), 倾斜法线 45度, 即入射角 45度(如图 4d所示),倾斜法线 60度, 即入射角 60度(如图 4e所示),观察发现, 入射角 0度时, 观察的颜色为如图 4a所示的蓝色, 入射角 15度时, 观察的颜色为如图 4b所 示的深蓝色, 入射角 30度时, 观察的颜色为如图 4e所示的深蓝绿, 入射角 45度时, 观察的 颜色为如图 4d所示的绿色, 入射角 60度时, 观察的颜色为如图 4e所示的紫色, 所以, 本实 施例中, 入射角 0度至入射角 30度之间时, 观察的颜色变化微弱不明显, 随着角度的增大, 颜色变化急剧明显, 45度观察到的颜色可能变化到 0度时颜色的临界色(光谱色内相邻的颜 色), 观察角度到 60时颜色甚至会变化到一个间隔邻近色 (光谱上近相邻的颜色), 例如在 0 度时是绿色时, 45度到 60度时已变成紫红色, 或者在 0度时是蓝色时, 45度变为绿色, 到 60度时已变成紫色, 即本实施例的功能膜片 100在大角度时实现变色, 由一种颜色直接变为 另一种颜色。
因此, 本实施例提供的功能膜片 100通过将至少三层结构的中间任—层厚度为至少三 层结构的其他任一一层厚度的 2〜3倍时, 实现了在大角度发生变色的目的。
需要说明的是, 包括 7层结构的镀膜层 20中, 还可以将中间层中的金属铟层 22a、 第二 氧化硅层 23a、第一氧化铌层 24a或第三氧化硅层 25a的厚度设置为其他人一层厚度的 2-3倍。
