具体实施方式
在本文中所披露的范围的端点和任何值都不限于该精确的范围或值，这些范围或值应当理解为包含接近这些范围或值的值。对于数值范围来说，各个范围的端点值之间、各个范围的端点值和单独的点值之间，以及单独的点值之间可以彼此组合而得到一个或多个新的数值范围，这些数值范围应被视为在本文中具体公开。
第一方面，本公开提供了一种3D玻璃金属复合体，如图1和图2所示，该3D玻璃金属复合体包括3D玻璃盖板10、塑胶框体20和金属边框30，所述金属边框30的上表面和所述3D玻璃盖板10的边面相对设置，所述塑胶框体20的至少一部分形成在所述3D玻璃盖板10的边面和金属边框30上表面(朝向所述3D玻璃盖板的一侧表面)之间，且所述3D玻璃盖板10、所述塑胶框体20和所述金属边框30的外周沿所述3D玻璃盖板的曲度无台阶平滑过渡。
本公开的3D玻璃金属复合体中，本领域技术人员应该理解的是：3D玻璃盖板的边面是指3D玻璃热弯前平面玻璃的(外周)侧表面，也可以成为平面玻璃的厚度面；所述塑胶框体(固化的、硬的塑胶框体)形成在所述3D玻璃盖板的边面和金属边框的上表面之间，即所述3D玻璃盖板、所述塑胶框体、所述金属边框按顺序依次设置，且三者的外周(相对于3D玻璃向外突出的一侧)沿所述3D玻璃盖板的曲度(玻璃弯曲后的延伸方向)无台阶平滑过渡。
所述平滑过渡至少应该理解为所述塑胶框体、所述金属边框和所述3D玻璃盖板的外周面位于同一曲面上，也就是说所述塑胶框体和所述金属边框的外周面沿3D玻璃盖板的外周面延伸。
本公开的3D玻璃金属复合体中，所述金属边框30包括一体成型的外框31和内框32，所述外框31的上表面与所述3D玻璃盖板10的边面相对设置，所述内框32形成在所述外框31的内部。在这种结构中，外框31主要起到壳体的作用，而内框32可以用于与内部构件结构匹配，可以在内框32上形成卡扣结构，以固定内部构件的位置，该内框32和外框31的下表面还可以配合形成与其他框体相连的适配结构。为了进一步增加3D玻璃盖板10与金属边框30之间的结合力，如图3所示，根据本发明的一个实施例，所述塑胶框体20的外周与所述外框31的外周相对应、塑胶框体20的内周与所述内框32的内周相对应的形成在所述3D玻璃盖板10与所述金属边框30之间。在这种情况下，增加了塑胶框体20与3D玻璃盖板10、以及与金属边框30之间的结合面积，进而有利于增加3D玻璃盖板10与 金属边框30之间的结合强度。
本公开的3D玻璃金属复合体中，为了进一步增加3D玻璃盖板10与金属边框30之间的结合力，如图3所示，优选情况下，所述内框32的上表面高于所述外框31的上表面；优选所述内框32的上表面与所述外框31的上表面弧形过渡连接。此时外框31的上表面的宽度(垂直于外框中边的延伸方向的长度)大于3D玻璃盖板10的边面的宽度，以预留有所述塑胶框体20的填充空间。在这种结构中，增加了塑胶框体20与金属边框30之间的结合面积，进而有利于增加3D玻璃盖板10与金属边框30之间的结合强度。
本公开的3D玻璃金属复合体中，对于3D玻璃盖板10、塑胶框体20、以及金属边框30的厚度可以没有特殊要求，可以根据实际需求进行相应设计，例如玻璃盖板10的厚度(即边面的宽度)可以为0.3-2mm，此时塑胶框体20位于玻璃盖板10的边面与金属框体30中外框31之间的厚度为0.5-1mm，金属边框30中外框31的上表面的宽度比玻璃盖板10中边面的宽度大0.5-2mm，金属边框30中内框32的宽度为1-2mm，内框32的上表面比外框31的上表面高0.1-2.5mm。
本公开的3D玻璃金属复合体中，3D玻璃盖板10可以为单曲玻璃盖板(一组相对设置的边缘弯曲形成)，也可以为双曲玻璃盖板(两组相对设置的边缘同时弯曲形成)。优选情况下，所述3D玻璃盖板为双曲玻璃盖板，该双曲玻璃盖板与金属边框的结构力更为均匀、稳定。
本公开的3D玻璃金属复合体中，塑胶框体20的材料可以为热塑性塑料，也可以为热固性树脂。所述热塑性树脂可以选自PC、PA、PPS和PBT等，所述热固性树脂可以选自酚醛树脂、环氧树脂、邻苯二甲酸二烯丙酯等。为了明显提高3D玻璃盖板与金属边框间的结合力，且明显降低碎屏风险，如本公开的一个实施例，塑胶框体的材料为聚酰胺(PA)、玻璃纤维(GF)、聚碳酸酯(PC)和聚苯硫醚(PPS)中的至少一种；如本公开的另一个实施例，塑胶框体的材料为聚酰胺、聚碳酸酯和聚苯硫醚中的至少一种与玻璃纤维的混合物；如本公开的再一个实施例，塑胶框体的材料为聚酰胺和玻璃纤维的混合物。
在本公开的一个实施例中，在塑胶框体中，聚酰胺、聚碳酸酯和聚苯硫醚中的至少一种的总重量与玻璃纤维的重量的比值为(0.5-5)：1。进一步在本公开的另一个实施例中该比例为(1-3)：1。本领域技术人员应该理解的是，塑胶框体中含有聚酰胺、聚碳酸酯和聚苯硫醚中的一种时，聚酰胺、聚碳酸酯和聚苯硫醚中的至少一种的总重量为该一种的重量，塑胶框体中含有聚酰胺、聚碳酸酯和聚苯硫醚中的两种以上时，聚酰胺、聚碳酸酯和聚苯 硫醚中的至少一种的总重量为该两种以上的重量和。本公开中，聚酰胺、玻璃纤维、聚碳酸酯和聚苯硫醚可通过商购获得。
本公开的3D玻璃金属复合体中，对于金属基材没有特别的限定，可以为本领域常用的各种金属基材，在本公开的一个实施例中，金属基材为不锈钢基材或铝合金基材。
本公开的3D玻璃金属复合体中，为了进一步提高3D玻璃盖板10与金属基材间的结合力，且明显降低碎屏风险，在本公开的一个实施例中，金属边框的表面形成有阳极氧化膜层，且在该阳极氧化膜层的外表层进一步形成有微孔。前述金属边框可以通过包括如下处理步骤的方法制备得到：将不锈钢或铝合金依次进行加工成型、打磨、化学抛光、喷砂处理、阳极氧化处理、微孔处理和贴膜处理。具体的步骤详见后述相应内容。
第二方面，本公开提供了一种3D玻璃金属复合体的制备方法，所述方法包括：(1)提供3D玻璃盖板10(如图4所示)，并在所述3D玻璃盖板10的边面上涂布活化剂，烘干；(2)提供金属边框预制体30ˊ(如图5所示)，所述金属边框预制体30ˊ相对于金属边框30的最终结构预留有沿所述金属边框30的外周向外延伸的预留部分33；(3)将步骤(1)得到的3D玻璃盖板10与所述金属边框预制体30ˊ置于注塑模具中，在3D玻璃盖板10的边面与所述金属边框预制体30的上表面之间填充注塑料，通过注塑得到3D玻璃金属复合预制体(如图6所示)；(4)对所述3D玻璃金属复合预制体进行切削处理，去除金属边框预制体30ˊ中预留部分33，得到所述3D玻璃金属复合体。
本公开的发明人在对玻璃与金属的结合力进行研究的过程中发现，通过注塑(填充注塑料)的方式能够提高玻璃和金属之间结合力，然而3D玻璃与平面玻璃不同，鉴于3D玻璃的特殊结构，以及3D玻璃盖板和金属框架在加工过程中所存在的加工公差，很难使得3D玻璃盖板与金属框架的尺寸完全匹配，往往在注塑后，3D金属盖板、塑胶框体和金属框架的外周还是会存在明显的缝隙和台阶，影响产品的外观及密封性。基于这一问题的存在，本公开的发明人再次对方法进行了改进，提出了在注塑过程中采用金属边框预制体的方案。该金属边框预制体相对于金属边框的最终结构预留有沿所述金属边框的外周向外延伸的预留部分，在注塑的过程中，预留部分能够对向外溢流的注塑料起到一定的阻挡作用，进而使得注塑料能够更紧密的固化在3D玻璃基板与金属框架之间，形成稳定密封的结构；而在注塑后，对3D玻璃金属复合预制体进行切削处理(即进行CNC加工)，去除金属边框预制体中预留部分(同时去除塑胶边框中多余的部分)，有利于美化所制备的3D玻璃金属复合体的美观性。
本公开的方法中，根据本公开的一个实施例，所述金属边框30包括一体成型的外框31和内框32，所述外框31与所述3D玻璃盖板10的边面相对设置，所述内框32形成在所述外框31的内部，所述预留部分33形成在所述外框31的外周。根据本公开的一个实施例，所述内框32的上表面高于所述外框31的上表面，所述内框32的上表面与所述外框31的上表面弧形过渡连接。此时外框31(不包括预留部分)的上表面的宽度(垂直于外框中边的延伸方向的长度)大于3D玻璃盖板边面的宽度，以预留有所述塑胶框体20的填充空间。
根据本公开的一个实施例，所述注塑模具包括阴模和阳模，所述阴模的内部具有与所述3D玻璃盖板的外表面结构匹配的内表面；所述阳模包括侧壁结构与所述金属边框预制体的内壁相匹配的柱状镶块，所述金属边框预制体可以灵活地套设在所述柱状镶块上，且所述柱状镶块的上表面与所述3D玻璃盖板的内表面结构匹配。所述阳模还包括能够套设在所述柱状镶块上、并能够相对所述柱状镶块上下移动的环形镶块，所述环形镶块套设在柱状镶块上时形成有能够与所述金属边框预制体结构匹配的环形槽。
本公开方法中，所述步骤(3)中注塑得到3D玻璃金属复合预制体包括：将所述步骤(1)得到的3D玻璃盖板10置于所述阴模中；将所述环形镶块套设在柱形镶块上形成相应阳模，将所述金属边框预制体30ˊ置于所述阳模中；推动环形镶块沿柱形镶块移动至所述阴模与阳模合模状态，在3D玻璃盖板与所述金属边框预制体之间的空隙处(包括由3D玻璃盖板内壁、柱形镶块外币与金属边框预制体之间的空间处)填充注塑料，并注塑得到3D玻璃金属复合预制体。
本公开的方法中，沿垂直于所述金属边框外边缘并向外延伸的方向，所述预留部分33的宽度为1-5mm。
本公开的方法中，在所述填充注塑料的过程中，所述注塑料充满3D玻璃盖板10与所述金属边框预制体30ˊ之间的空隙，优选使得注塑料的外部边缘突出于所述3D玻璃盖板10的外表面、位于所述金属边框预制体30ˊ的外边缘之间。通过增加注塑料的用量，有利于使得所制备的塑胶框体的密实度，优化密封效果。
本公开的方法中，为了进一步增加3D玻璃盖板10与塑料框体20之间结合力，在玻璃盖板10的弯曲部分的内侧、或者侧边的内侧还形成有凸棱，在填充注塑料的过程中，使得塑料包覆在该凸棱的外周，以增加玻璃盖板10余塑料边框20之间的结合面积，增加结合力。
本公开的方法中，如本公开的一个实施例，该方法还包括：步骤(1)中，在所述3D 玻璃盖板的边面上涂布活化剂的步骤之前，至少在玻璃盖板的边面上涂布油墨，固化。其中，可以根据3D玻璃金属复合体的应用情况来确定在3D玻璃盖板的哪些部位上涂布油墨，例如，如果3D玻璃金属复合体被用作前屏盖板壳体时，仅仅在3D玻璃盖板的边缘上涂布油墨，主要起遮蔽ITO电路的作用；如果3D玻璃金属复合体被用作后屏壳体时，在3D玻璃盖板的内表面(包括内表面的边缘)上涂布油墨，主要起显示后屏盖板3D玻璃金属复合体颜色的作用。
本公开的方法中，步骤(1)中，为了提高玻璃盖板与金属基材间的结合力，且降低碎屏风险，对3D玻璃盖板为边面进行了粗糙化处理的3D玻璃盖板，以增加其表面粗糙度。粗糙化处理为本领域技术人员所熟知，在此不再赘述。
本公开的方法中，步骤(1)中，对于油墨没有特别的限定，可以为本领域常用的各种油墨，如本公开的一个实施例油墨为UV油墨或热固油墨。对于涂布油墨的方式没有特别的限定，可以为能够涂布的任何方式。为了方便生产，根据本公开的一个实施例，涂布油墨的方式为丝印，丝印的油墨的厚度为5-15μm。具体丝印的方法为本领域技术人员所熟知，在此不再赘述。对于涂布油墨后进行的固化的条件没有特别的限定，可以根据油墨的种类进行选择，均为本领域常用的各种条件，其中，油墨为UV油墨时，固化的方式为曝光，曝光条件包括：功率为500-1200kW，时间为1-5min；油墨为热固油墨时，固化的方式为烘干，烘干的条件包括：温度为80-90℃，时间为50-100min。

本公开的方法中，步骤(2)中，对于金属边框的基材没有特别的限定，可以为本领域常用的各种金属基材，根据本公开的一个实施例，金属基材为不锈钢基材或铝合金基材。
其中，现有技术的金属边框一般通过包括如下处理步骤的方法制备得到：将不锈钢或铝合金依次进行加工成型、打磨、化学抛光、喷砂处理、阳极氧化处理和贴膜处理，为了进一步提高玻璃盖板与金属基材间的结合力，且进一步降低碎屏风险，根据本公开的一个实施例，金属边框通过包括如下处理步骤的方法制备得到：将不锈钢或铝合金依次进行加工成型、打磨、化学抛光、喷砂处理、阳极氧化处理、微孔处理和贴膜处理(在金属边框上贴膜是为了防止阳极氧化膜被划伤)。其中，在阳极氧化处理后增加微孔前处理，使得阳极氧化膜层的外表层进一步形成微米级的大的腐蚀孔，通过这种腐蚀再造孔，在后续的成型过程中，塑胶材料在注塑过程中会更容易直接进入基材表面孔中，从而在形成塑胶框体后与基材形成良好的结合，能够进一步提高玻璃盖板与金属基材间的结合力。
根据本公开的一个实施例，微孔处理的方式为：将阳极氧化处理得到的基材浸泡到刻蚀液中，在阳极氧化膜层外表层形成孔径为200nm-2000nm的腐蚀孔。其中，刻蚀液可以为将阳极氧化膜膜层腐蚀的溶液，例如，一般用能溶解氧化铝的溶液调节浓度即可，可以为酸/碱刻蚀液，例如可以选自pH为10-13的溶液。根据本公开的一个实施例，刻蚀液为pH为10-13的单一碱性溶液或复合缓冲溶液，pH为10-13的单一碱性溶液可以为Na 2CO 3、NaHCO 3、NaOH、K 2CO 3、KHCO 3、KOH等的水溶液。根据本公开的一个实施例，刻蚀液为Na 2CO 3和/或NaHCO 3水溶液，能够使腐蚀孔在基材表面均匀分布，并且孔径均匀，能够使玻璃盖板与基材的结合性能更佳。上述刻蚀液的固含量可以为0.1-15重量％。复合缓冲溶液可以为可溶性磷酸氢盐和可溶性碱的混合溶液，例如磷酸二氢钠和氢氧化钠的水溶液，磷酸二氢钠和氢氧化钠的水溶液的固含量可以为0.1-15重量％，也可以为K 3PO 4和K 2HPO 4的水溶液，复合缓冲溶液还可以为氨水溶液、肼水溶液、肼衍生物水溶液、水溶性胺系化合物水溶液、NH 3-NH 4Cl水溶液等。将阳极氧化处理得到的基材浸泡到刻蚀液中包括将基材反复多次浸入 刻蚀液中，每次浸渍的时间可以为1-60min，每次浸渍后用去离子水洗净，浸入的次数可以为2到10次。洗净可以是放入水洗槽中清洗1到5min，或者放入水洗槽中放置1到5min。
其中，对于加工成型、打磨、化学抛光、喷砂处理、阳极氧化处理和贴膜处理的方法没有特别限定，可以为本领域常用的各种方法，此均为本领域技术人员所熟知，例如，喷砂处理的条件可以包括：喷砂压强为0.23-0.25MPa，往复2-4次，走速为12-22Hz，其中，可以使用205陶瓷砂，摇摆频率可以为33Hz(机台固定频率)。阳极氧化处理的条件可以包括：电解液中硫酸浓度为10-30重量％，铝离子浓度为10-30g/L；温度为15-25℃，电流密度为0.6-3A/dm 2，电压为10-20V，氧化时间为30min-50min。
本公开的方法中，为了进一步提高3D玻璃盖板与金属基材间的结合力，且进一步降低碎屏风险，根据本公开的一个实施例，该方法还包括：步骤(2)中，在所提供的金属边框预制体的上表面上涂布活化剂，烘干。其中所采用的活化剂、活化剂的涂布方式，以及烘干条件参见前述描述。
本公开的方法中，根据本公开的一个实施例，步骤(3)中，注塑的方式为常温注塑，进一步地，注塑的条件包括：注塑宽度(注塑后玻璃盖板10的边面与金属框体30的外框31的上表面之间的厚度)为0.5-1mm，模具温度为15-35℃，注塑料温度为200-300℃。
本公开的方法中，为了明显提高玻璃盖板与金属基材间的结合力，且明显降低碎屏风险，根据本公开的一个实施例，注塑料为聚酰胺、玻璃纤维、聚碳酸酯和聚苯硫醚中的至少一种，进一步为聚酰胺、聚碳酸酯和聚苯硫醚中的至少一种与玻璃纤维的混合物，更进一步为聚酰胺和玻璃纤维的混合物。
其中，根据本公开的一个实施例，聚酰胺、聚碳酸酯和聚苯硫醚中的至少一种的总重量与玻璃纤维的重量的比值为(0.5-5)：1，进一步为(1-3)：1。本领域技术人员应该理解的是，注塑料中含有聚酰胺、聚碳酸酯和聚苯硫醚中的一种时，聚酰胺、聚碳酸酯和聚苯硫醚中的至少一种的总重量为该一种的重量，注塑料中含有聚酰胺、聚碳酸酯和聚苯硫醚中的两种以上时，聚酰胺、聚碳酸酯和聚苯硫醚中的至少一种的总重量为该两种以上的重量和。
