在本申请的一个方面,本申请提出了一种制备曲面玻璃板材的方法。根据本申请的实施例,参考图1,该方法包括:
S100:第一湿法刻蚀处理
根据本申请的实施例,在该步骤中,对平面玻璃板进行第一湿法刻蚀处理,以便在平面玻璃板上形成第一纹理面。根据本申请的实施例,平面玻璃板的形状、大小和厚度不受特别限制,本领域技术人员可以根据需要进行选择。例如,根据本申请的实施例,可以在对 平面玻璃板进行第一处理之前,进一步包括对平面玻璃板裁料的工序。根据本申请的具体实施例,在该工序中,可以采用数控机床并采用金刚石刀具对平面玻璃板进行裁切,以得到预定尺寸的平面玻璃板。根据本申请的实施例,可以在平面玻璃板的至少一部分表面进行第一处理,以便在平面玻璃板的至少一部分表面形成第一纹理面。
具体的,在该步骤中,可以采用刻蚀液对平面玻璃板进行刻蚀,即将平面玻璃板浸泡在蚀刻液内进行蚀刻。根据本申请的实施例,参考图2,湿法刻蚀可以包括以下步骤:
S10:在平面玻璃板表面设置掩膜
在该步骤中,在平面玻璃板表面设置掩膜。根据本申请的实施例,设置掩膜的具体方式不受特别限制,例如,可以在平面玻璃板表面印刷感光油墨,利用感光油墨形成掩膜,用来遮蔽不需要进行蚀刻的平面玻璃板区域。具体的,可以首先根据设计的纹理或图案制作相应的菲林片,然后通过菲林片曝光显影固化,来形成对对应纹理或图案的遮蔽。
S20:将平面玻璃板设置有掩膜的一侧置于刻蚀液中
在该步骤中,将平面玻璃板设置有掩膜的一侧置于刻蚀液中,进行刻蚀。根据本申请的实施例,刻蚀液的种类和具体的刻蚀方式不受特别限制,只要能够在平面玻璃板上形成刻蚀纹理即可,例如,根据本申请的具体实施例,可以将印刷好遮蔽油墨的平面玻璃板浸入以氢氟酸为主的蚀刻溶液中进行蚀刻。
S30:去除掩膜
在该步骤中,去除掩膜,以便形成蚀刻后的第一纹理面。根据本申请的实施例,可以采用特定的弱碱性(浓度:1-5%)溶液去除遮蔽的油墨,由此,油墨遮蔽区域的平面玻璃板不被蚀刻,为通透光泽效果,经过蚀刻的平面玻璃板区域形成了第一纹理面,为雾面哑光效果。由此,第一纹理面和未刻蚀的平面玻璃板区域组成了第一层深度上及视觉上的纹理图案效果。
根据本申请的具体实施例,该步骤形成的第一纹理面的光泽度可以为25-65,粗糙度可以为0.1-0.2,雾度可以为10%-20%,透过率可以不低于70%,反射率可以不小于10%,如可以为10%~98%。本领域技术人员可以根据想到达到的纹理效果来进行选择。例如,具体的,第一纹理面的光泽度可以为35~65,粗糙度可以为0.1-0.15,雾度可以为10%-15%,透过率可不低于85%,反射率不小于10%。根据本申请的实施例,第一纹理面的厚度可以为5微米~200微米。由此,所形成的第一纹理面具有精美的纹理效果,并且蚀刻后的平面玻璃板依然具有良好的机械强度。
需要说明的是,在该步骤中,所采用的湿法刻蚀的刻蚀液成分不受特别限制,本领域技术人员可以根据实际情况进行选择。例如,刻蚀液可以为含有氢氟酸、硝酸、磷酸以及醋酸的混酸水溶液。由此,可以简便地实现对平面玻璃板的刻蚀,且刻蚀后不会显著影响该 平面玻璃板的整体机械强度。例如,根据本申请的具体实施例,基于刻蚀液的总质量,该刻蚀液可以包括:25~55wt%的氢氟酸、6~25wt%的硝酸、15~45wt%的磷酸、0~25wt%的醋酸以及0~25wt%的硫酸。更具体地,该刻蚀液可以包括25~45wt%的氢氟酸,6~25wt%的硝酸,15~35wt%的磷酸;以及5~25wt%的醋酸。
第一湿法刻蚀处理具体参数可以根据需要形成的第一纹理面的物理参数进行调节。例如,根据本申请的实施例,第一湿法刻蚀处理的刻蚀温度可以为25~40摄氏度,刻蚀速度可以为5~8微米/分钟,刻蚀时间为3~6分钟,刻蚀深度为15~30微米。由此,可以简便地形成外观较佳的第一纹理面,且不会由于刻蚀过度,影响该平面玻璃板的整体机械强度。
S200:形成第二纹理面
根据本申请的实施例,在该步骤中,对形成有第一纹理面的平面玻璃板进行第二湿法刻蚀处理,以便在平面玻璃板上形成第二纹理面。根据本申请的实施例,第二湿法刻蚀处理形成的第二纹理面,只要在覆盖位置、刻蚀深度、光泽度、粗糙度、雾度、反射率以及透过率的至少之一上具有差异即可。由此,可以利用玻璃板材自身所具有的透明性能,通过第一纹理面以及第二纹理面实现三维纹理的外观效果。
根据本申请的实施例,第二湿法刻蚀处理也可以采用刻蚀液对平面玻璃板进行刻蚀,即通过设置掩膜、利用刻蚀液浸泡、去除掩膜等步骤,实现第二纹理面的形成。根据本申请的实施例,第二湿法刻蚀处理所采用的刻蚀液,可以与第一湿法刻蚀处理所采用的刻蚀液相同,也可以不相同。根据本申请的具体实施例,第二湿法刻蚀处理所采用的刻蚀液可以包括40~55wt%的氢氟酸;6~25wt%的硝酸;25~45wt%的磷酸;以及6~25wt%的硫酸。形成的第二纹理面的光泽度可以为25-45,粗糙度可以为0.15-0.2,雾度可以为15%-17%,透过率可以为70~80%,反射率不小于20%。
类似地,第二湿法刻蚀处理具体参数可以根据需要形成的第二纹理面的物理参数进行调节。例如,根据本申请的实施例,第一湿法刻蚀处理的刻蚀温度可以为20~30摄氏度,刻蚀速度为3~6微米/分钟,刻蚀时间为2~5分钟,刻蚀深度为10~15微米。由此,可以简便地形成外观较佳的第二纹理面,且不会由于刻蚀过度,影响该平面玻璃板的整体机械强度。
如前所述,前面形成的第一纹理面以及第二纹理面的具体位置,不受特别限制。下面,根据本申请的具体实施例,对上述纹理面的具体位置进行详细说明:
根据本申请的实施例,参考图3~图5,第一纹理面110以及第二纹理面120在平面玻璃板100上的投影,可以完全不重合(如图3所示),可以有部分重合(如图4所示,具有重叠部20),也可以完全重合(如图5所示)。也即是说,第一纹理面110可以覆盖平面玻璃板100的部分表面,第二纹理面120覆盖平面玻璃板100未被第一纹理面110覆盖的至少 一部分区域。或者,第二纹理面120覆盖第一纹理面110的至少一部分区域。或者,第一纹理面110覆盖平面玻璃板100的部分表面,第二纹理面120覆盖第一纹理面110的至少部分区域,以及平面玻璃板上未被第一纹理面覆盖的至少部分区域。
S300:进行折弯处理
在该步骤中,对形成有第一纹理面以及第二纹理面的平面玻璃板进行弯折处理,以便在平面玻璃板上形成曲面,进而形成具有层次分明的立体纹理效果的曲面玻璃板。根据本申请的实施例,折弯处理的具体方法不受特别限制,例如,根据本申请的具体实施例,可以对平面玻璃板进行热压处理,平面玻璃板可以根据提前设计的三维曲面模具得到三维曲面效果。根据本申请的实施例,折弯处理的方向不受特别限制,第一纹理面和第二纹理面可以位于三维曲面玻璃的正面或背面。
根据本申请的实施例,参考图7,在进行折弯处理后,制备曲面玻璃板材的方法还可以进一步包括:
S400:进行光学镀膜处理
在该步骤中,对形成有曲面的平面玻璃板进行光学镀膜处理。根据本申请的实施例,可以在曲面玻璃板的背面进行光学镀膜,也即是说,在曲面玻璃远离第一纹理面等结构的一侧进行光学镀膜,以此来调整曲面玻璃板的透射率和反射率,使曲面玻璃板的通透感更强,可以实现更佳的纹理效果。根据本申请的实施例,镀膜的材料、透过率和反射率不受特别限制,本领域技术人员可以根据需要进行选择,例如,根据本申请的具体实施例,镀膜靶材可以为氧化硅、氧化钛组合的叠加镀层,光学镀膜的透射率可以为75%-95%,反射率可以为5%-20%。
S500:进行喷墨着色处理
在该步骤中,对经过光学镀膜处理的曲面玻璃板进行喷墨着色处理。根据本申请的实施例,喷墨着色处理的颜色不受特别限制,可以根据设计的图案颜色调配油墨颜色。根据本申请的实施例,可以采用喷墨方式进行有色油墨附着。喷墨着色后,前面步骤所产生的精细纹理更加明显,可以形成多层纹理交织的立体效果。
